R&D Tax Credit Training for Accountants: Teach Staff to Build Evidence Before Calculating the Credit

What Is R&D Tax Credit Training for Accountants?

R&D tax credit training develops an accountant’s ability to convert a taxpayer’s technical development activity into a substantiated Section 41 research-credit file before computing Form 6765.

The sequence matters.

Weak workflows often begin like this:

A stronger workflow begins with:

That makes this training a direct application of Tax Workpaper Training for Staff Accountants, Professional Skepticism Training for Junior Accountants, and the Workpaper Review Checklist.

Why the R&D Credit Is a Staff-Development Problem

R&D credit preparation forces staff to bridge two languages:

• Technical language: engineering problems, software architecture, formulations, prototypes, testing, defects, tolerances, performance constraints, alternatives.
• Tax language: qualified research, business components, QREs, funded research, Section 174A, Section 280C, fixed-base percentage, ASC, controlled groups, Form 6765.

An accountant can calculate the credit correctly and still have a weak claim if the activity file cannot explain why the costs qualify.

I have practiced public accounting since 1990, founded my accounting firm in 1993, and helped grow Howard, Howard and Hodges from three people to approximately 50 staff. Since 2020, I have built SkillAbility around a recurring issue: firms often hand technical work to staff without converting reviewer judgment into observable preparation steps.

R&D credit work makes that gap expensive.

“Can populate Form 6765” is not the competency.

“Can identify a business component, prove the four-part test, reconcile QREs, apply exclusions, compare computation methods, coordinate Section 174A/280C, and hand the reviewer an evidence-indexed file” is.

Current R&D Tax Credit Facts Staff Should Know in 2026

Two developments materially change the training environment.

1. Section 174A restored current deductions for domestic R&E beginning in 2025

P.L. 119-21 added Section 174A. For tax years beginning after December 31, 2024, domestic research or experimental expenditures can generally be deducted currently. Taxpayers can instead elect to capitalize domestic R&E and amortize it over at least 60 months beginning when benefits are first realized. Foreign research or experimental expenditures remain subject to separate capitalization and 15-year amortization treatment under current law.

Rev. Proc. 2025-28 provides method-change and transition procedures, including options for remaining unamortized domestic R&E from tax years beginning after 2021 and before 2025 and special retroactive options for qualifying small-business taxpayers.

2. Form 6765 is becoming more business-component specific

The current Form 6765 instructions provide:

• Section G is optional for tax years beginning before 2026.
• For tax years beginning after 2025, Section G is generally required unless an exception applies.
• Required filers generally report at least 80% of total QREs by business component, but no more than the top 50 business components.
• Remaining business components are reported in aggregate.

Current Form 6765 facts

Chart: Form 6765 Is Moving From Summary Reporting Toward Business-Component Reporting

*Subject to current exceptions, including certain qualified small businesses making the payroll tax election and certain original-return taxpayers with controlled-group QREs ≤ $1.5 million and average annual gross receipts for the prior three years ≤ $50 million.

The CREDIT READY Framework

C — Start With the Business Component, Not the Expense Account

The current Form 6765 instructions define a business component as a product, process, computer software, technique, formula, or invention held for sale, lease, or license—or used by the taxpayer in its trade or business.

The four-part test applies separately to each business component.

Examples of possible business components

• A new medical device
• A redesigned manufacturing process
• A software feature or application
• A new chemical formulation
• A production technique
• A machine or tooling design
• A new algorithm
• A reliability improvement to an existing product
• A process-control system

“Engineering department” is not a business component.

“2026 innovation” is not a business component.

“R&D project” can be too broad if it contains multiple products or processes that must be tested separately.

Use stable identifiers

The current Section G instructions specifically contemplate a business-component name or unique alphanumeric identifier that is consistent with the taxpayer’s books and records.

That gives CPA firms a practical control:

A useful master file can include:

• Business component ID
• name
• type: product, process, or other
• entity/EIN
• project owner
• start/end dates
• commercial production date
• technical objective
• uncertainty
• qualified research period
• excluded activity period
• employees
• supplies
• contractors
• QRE total

The business component creates the evidence container

Once staff know the component, they can ask the right questions.

Without the component, R&D interviews tend to produce broad statements such as:

• “We are always innovating.”
• “Our engineers solve difficult problems.”
• “We build custom solutions.”
• “Our software changes constantly.”

None of those statements proves qualified research.

Teach the Four-Part Test as an Evidence Test

The current Form 6765 instructions describe qualified research through four core requirements.

Do not train the four-part test as four paragraphs

A common R&D credit workpaper contains a narrative with four headings and conclusory language beneath each heading.

For example:

“The taxpayer engaged in a process of experimentation to improve the performance of its product.”

That states the test.

It does not prove the test.

A stronger workpaper answers:

• What was uncertain?
• What alternatives were considered?
• What did the team test?
• What failed?
• What changed after failure?
• What technical result was discovered?

R + E + D — Document Uncertainty, Experimentation, and Qualified Purpose

Technical uncertainty should exist at the beginning

The IRS research-credit audit guidance describes uncertainty in terms of whether available information established the capability or method for developing/improving the product—or the appropriate design.

Train staff to capture the uncertainty prospectively where possible.

Good uncertainty questions

• Could the desired performance be achieved within the physical constraints?
• Which architecture could handle the required load?
• Which formulation could produce the desired stability?
• Could the process meet the new tolerance at production speed?
• Which material would survive the temperature/pressure cycle?
• How could the system integrate incompatible data sources without unacceptable latency?

Weak uncertainty statements

• “The project was difficult.”
• “The team did not know how long it would take.”
• “The customer changed requirements.”
• “The company had never done this before.”
• “The outcome was not guaranteed.”

Business, scheduling, financial, or managerial uncertainty is not automatically technical uncertainty.

What counts as a process of experimentation?

The evidence should show evaluation of alternatives through activities such as:

• Modeling
• simulation
• systematic trial and error
• prototyping
• bench testing
• unit/integration testing
• engineering calculations
• design comparisons
• material trials
• algorithm benchmarking

Failure is valuable evidence

A failed prototype can be more persuasive than a polished year-end narrative because it shows:

• The team did not already know the answer
• An alternative was evaluated
• technical information was learned
• the next iteration responded to the result

Qualified purpose

The process of experimentation must relate to a new or improved:

• Function
• performance
• reliability
• quality

Style, taste, cosmetic, or seasonal design changes do not qualify merely because creative effort occurred.

I — Excluded Activities: Evidence Also Has to Prove What Was Removed

The current Form 6765 instructions identify several categories of excluded research.

Commercial production needs a date

Do not let the phrase “still improving the product” keep all later activity inside the credit.

The file should identify:

• Prototype/testing phase
• release/production date
• post-release bug fixes
• routine quality control
• customer support
• later discrete improvement projects

Internal-use software

The current Form 6765 instructions impose additional requirements for certain software developed primarily for internal use. Depending on the software, the higher-threshold-of-innovation test can require evidence that the software is innovative, involves significant economic risk because of technical uncertainty, and is not commercially available for the intended use without qualifying modifications.

Software classification should happen before the staff member assigns QREs.

Shrink-back is a qualification tool, not an excuse to claim everything

IRS guidance recognizes a “shrinking-back” rule.

If an entire business component does not satisfy the Section 41 requirements, the analysis can move to the most significant subset of that component until a qualifying subset is found—or the smallest element still fails.

Example:

A new manufacturing line as a whole may contain routine equipment integration plus a genuinely uncertain high-speed injection subsystem. If the whole line does not satisfy the test, the team should analyze whether the discrete subsystem does.

T — Only Build QREs After the Activities Qualify

Qualified research expenses generally include:

• In-house wages for qualified services
• supplies used in qualified research
• certain rental/lease costs of computers
• applicable percentages of contract research expenses

The order should be:

Not:

Financial statement R&D is not automatically tax QRE

Financial accounting classifications and Section 41 tax rules are different systems.

Some book R&D costs may not be QREs.

Some qualified research costs may sit outside a book “R&D” department.

The accountant’s job is to reconcile—not equate—the systems.

Qualified Wages: What Did the Employee Actually Do?

The IRS audit guidance describes employee wage analysis as one of the most important phases of research-credit examination.

The key question is activity, not title.

Qualified services can include

• Conducting qualified research — directly performing the experimentation.
• Direct supervision — immediate, first-line supervision of qualified research.
• Direct support — directly supporting qualified research.

Higher-level management is not automatically direct supervision

The current Form 6765 Section G instructions expressly distinguish first-line direct supervision from higher-level management to whom first-line managers report.

Evidence for wage QREs

• Payroll records
• time tracking
• project-management records
• engineering tickets
• code commits
• lab notebooks
• calendars
• project meeting records
• technical deliverables
• employee interviews corroborated by contemporaneous records

The employee 80% “substantially all” wage rule

Under the qualified-services wage rules, if at least 80% of an employee’s services for the year are qualified services, the “substantially all” rule can allow all of that employee’s services to be treated as qualified services for this purpose. If the ratio is below 80%, use the actual qualified portion.

Officer wages deserve specific review

Current Form 6765 Section E asks for officer wages included in qualified wages.

That makes broad executive percentages especially visible.

A CEO who attends occasional product meetings is not automatically performing qualified research.

A founder who actively designs, codes, tests, or directly supervises technical experimentation can have qualifying services—but the file should prove the activity.

Supplies, Computer Rental, and Contract Research

Supplies

Current Form 6765 instructions include supplies used in the conduct of qualified research as a QRE category.

Staff should not assume every prototype or test item is a qualified supply.

The file should ask:

• Was the item used in qualified research?
• Is the item property of a character subject to depreciation?
• Was it consumed or incorporated during experimentation?
• Does the invoice tie to the business component?
• Did part of the cost relate to routine production?

Computer rental / lease

Form 6765 includes certain rental or lease costs of computers used in qualified research, subject to the detailed rules. The current instructions state that the computers must be located off the taxpayer’s premises and the taxpayer must not be the operator or primary user.

Cloud and hosted computing arrangements can require careful classification rather than assuming every technology invoice is a QRE.

Contract research

The current Form 6765 instructions generally include:

• 65% of qualifying payments to another person for qualified research
• 75% for certain qualified research consortium payments
• 100% for certain qualified energy research performed by specified eligible small businesses, universities, or federal laboratories

Those percentages apply only after the underlying research and contractual arrangement qualify.

Prepaid research

The current instructions state that prepaid contract research is treated as paid in the year the research is actually performed for this purpose.

Funded Research: Read the Contract Before Claiming the Credit

Research funded by another person or governmental entity is excluded from qualified research under Section 41.

For research performed for a customer, staff should identify:

• Who bears economic risk if the research fails?
• Is payment contingent on successful research?
• Does the taxpayer retain substantial rights to use or exploit the research results?
• What does the master services agreement say?
• Do statements of work change the risk allocation?
• Are milestone payments contingent or fixed?

IRS legal guidance has repeatedly focused on contractual risk and substantial rights when determining whether research performed for another party is funded.

Build a contract matrix

Do not let the project manager answer the tax-contract question alone

Technical staff can explain the research.

They may not know the legal allocation of risk and rights in the contract.

The accountant should reconcile the technical interview to the written agreement.

R — Coordinate Section 41 With Section 174A

The research credit and research-expenditure deduction are related, but they are not interchangeable.

Beginning with tax years after 2024, Section 174A generally allows current deductions for domestic research or experimental expenditures paid or incurred in the taxpayer’s trade or business.

A taxpayer can instead elect to capitalize and amortize qualifying domestic R&E over at least 60 months, beginning with the month benefits are first realized. Other elections can also affect timing.

Foreign R&E remains subject to separate mandatory capitalization and 15-year amortization under current law.

Why staff need a Section 41 ↔ Section 174A bridge

The current Form 6765 definition of qualified research incorporates domestic research or experimental expenditures under Section 174A as part of the four-part test.

But the Section 174A cost pool and the Section 41 QRE pool are not necessarily the same amount.

Transition amounts from 2022–2024

P.L. 119-21 and Rev. Proc. 2025-28 provide transition options for remaining unamortized domestic R&E amounts from tax years beginning after 2021 and before 2025.

Certain qualifying small-business taxpayers can also have retroactive options under the new law.

These are accounting-method and transition issues. Staff should identify the historical layers, but entity-specific elections and method changes should be manager/tax-method reviewed.

E — Section 280C: Control the Reduced-Credit Election Before the Return Is Filed

The current Form 6765 asks at the top of the form whether the taxpayer is electing the reduced credit under Section 280C.

The election must generally be made on the original timely filed return, including extensions, and cannot simply be changed later on an amended return for that year.

If the taxpayer makes the reduced-credit election

For the regular credit, the current Form 6765 uses 15.8% instead of the unreduced 20% multiplier for the applicable incremental amount.

For the ASC, the current form reduces the computed credit by multiplying it by 79%.

If the taxpayer does not elect the reduced credit

The current instructions require the taxpayer to reduce domestic Section 174A R&E expenditures otherwise taken as a deduction or charged to capital account by the research credit amount, with a supporting statement identifying the affected tax-return lines.

E — Regular Research Credit vs. Alternative Simplified Credit

After activities and QREs are supported, staff can calculate the credit.

Regular credit

The regular method generally applies a 20% credit rate to the qualifying incremental amount, subject to the fixed-base percentage, gross-receipts base, and the statutory minimum-base limitation. Under the reduced-credit election, the current form uses 15.8% instead.

Alternative Simplified Credit (ASC)

The ASC generally compares current-year QREs with 50% of the average QREs for the prior three years.

On the current Form 6765:

If the taxpayer had no QREs in any one of the prior three years, the form uses a 6% calculation on current QREs under the applicable rule.

Simplified ASC example

Assume:

• Current QREs: $1,000,000
• Prior-year QREs: $600,000
• Prior-year QREs: $700,000
• Prior-year QREs: $800,000

Prior-three-year average = $700,000.

50% of average = $350,000.

If the taxpayer makes the current reduced-credit election:

Calculate both methods where appropriate

The current Form 6765 instructions explicitly note that a taxpayer may want to calculate both methods for which it is eligible to determine the larger allowable credit.

But method selection should not distract from substantiation.

A — Form 6765 Section G: Business-Component Reporting Becomes a Filing Control

For tax years beginning after 2025, Section G is generally required unless a current exception applies.

Current exceptions include

• A qualified small business under Section 41(h)(3) that checks the box to claim the payroll tax credit; or
• An original-return taxpayer whose total QREs at the controlled-group level are $1.5 million or less and whose average annual gross receipts for the prior three tax years are $50 million or less.

80% / Top 50 reporting

If Section G is required, the current instructions generally require component-level reporting for:

• At least 80% of total QREs
• but no more than 50 business components
• listed in descending order by QRE amount

Remaining business components are reported in aggregate.

Section G asks for more than a project name

Current fields include information such as:

• EIN of the entity conducting research
• principal business activity code
• business-component name or unique identifier
• component type
• software type when applicable
• qualified wages by conduct / direct supervision / direct support
• supplies
• computer rental
• contract research

For amended research-credit refund claims, the current form also uses Section G to capture claim-related activity information.

Build the Section G file during the year

Waiting until tax preparation to identify the top QRE business components creates avoidable risk.

A better process:

Qualified Small Business Payroll Tax Credit

A qualified small business can elect to apply a portion of its research credit against qualifying payroll tax liability.

Current Form 6765 instructions define a qualified small business for this election generally as a corporation or partnership with:

• Gross receipts of less than $5 million for the tax year; and
• No gross receipts for any tax year before the five-tax-year period ending with the current tax year.

Other persons can qualify under the detailed aggregation rules.

Maximum election

The current maximum annual research credit that can be elected as a payroll tax credit is $500,000, subject to the detailed limits.

The election is made on the original timely filed income-tax return, including extensions.

The payroll tax credit is then claimed through Form 8974 with the applicable employment tax return.

Do not confuse “qualified small business” definitions

The research-credit payroll-tax QSB definition is different from other “small business” thresholds in the tax law, including the Section 174A transition small-business rules and eligible-small-business rules used for other credit limitations.

D — Amended Research Credit Claims Require a Stronger Business-Component File

Research credit claims for refund on amended returns have specific IRS validity requirements.

For claims filed after June 18, 2024, current IRS guidance requires the taxpayer to provide, at filing:

• All business components to which the Section 41 refund claim relates
• All research activities performed for each business component
• Total qualified employee wage expenses
• Total qualified supply expenses
• Total qualified contract research expenses

The IRS previously required names/titles of individuals and information each sought to discover at filing; as of June 18, 2024, those two filing items were waived, although the IRS may request that information during examination.

45-day perfection transition

The IRS has extended the transition period during which a deficient research-credit refund claim can receive a 45-day opportunity to perfect missing information through January 10, 2027.

That is procedural relief—not a documentation strategy.

BBA partnerships

BBA partnerships generally use an Administrative Adjustment Request rather than a normal amended partnership return, and current research-credit claim procedures coordinate with Forms 8985 and 8986.

Pass-through refund claims deserve entity-specific review.

Retrospective studies are harder than year-round evidence

When a firm tries to claim a missed credit two years later, it may have:

• Employees who left
• project systems that changed
• deleted test environments
• unclear project names
• no contemporaneous uncertainty statements
• contracts that are difficult to locate
• time percentages based on memory

That is exactly why staff training should move evidence capture into the operating year.

The R&D Credit Evidence Stack

The best evidence file is not the one with the most pages.

It is the one that lets a reviewer connect:

Layer 1 — project inception

• Project authorization
• technical objective
• initial requirements
• known constraints
• uncertainty statement
• alternative approaches
• business-component ID

Layer 2 — experimentation

• Design iterations
• prototype records
• engineering drawings
• lab notebooks
• test plans
• test results
• failed trials
• code commits
• issue/ticket history
• simulation outputs
• architecture decisions
• technical meeting notes

Layer 3 — people and qualified services

• Employee roster
• role by component
• conduct / direct supervision / direct support classification
• time records
• project assignments
• technical deliverables
• corroborating interviews

Layer 4 — cost support

• Payroll ledger
• W-2 wage reconciliation
• GL detail
• supply invoices
• contractor invoices
• contracts / statements of work
• computer-rental records
• allocation methodology

Layer 5 — tax reconciliation

• Section 174A pool
• Section 41 QRE bridge
• foreign R&E exclusion
• Section 280C election
• regular credit calculation
• ASC calculation
• controlled-group allocation
• acquisition/disposition adjustments
• base-year consistency workpaper

Layer 6 — return and defense

• Form 6765
• Section E questions
• Section F QRE summary
• Section G component detail
• Form 3800
• Form 8974 if applicable
• supporting statements
• e-file attachments
• permanent carryforward file

Controlled Groups, Acquisitions, and Consistency: The Credit Is Not Always Entity-by-Entity

Section 41 contains aggregation rules for controlled groups of corporations and businesses under common control.

Current Form 6765 instructions require controlled-group information and coordinated method/election treatment.

Staff should identify before calculation

• Parent/subsidiary relationships
• brother-sister ownership
• commonly controlled trades/businesses
• acquisitions during the year
• dispositions
• new expense categories
• changes in QRE characterization

Current Section E asks whether QREs relate to an acquisition/disposition and whether new categories of expenses were included.

If current-year expense categories are treated differently from base years, the base-year computation may need corresponding adjustments to preserve consistency.

Statistical Sampling and ASC 730: Advanced Tools Do Not Eliminate Documentation

Statistical sampling

Current Form 6765 instructions recognize statistical sampling when permitted and compliant with Rev. Proc. 2011-42.

But the IRS expressly notes that filing Form 6765 does not mean the Service accepted the sample as adequate substantiation.

Required Section G reporting still applies under the current instructions when Section G is otherwise required.

ASC 730 Directive

Certain large taxpayers with qualifying certified audited financial statements can use the IRS ASC 730 Directive framework.

The current Form 6765 instructions generally limit this directive to taxpayers with at least $10 million in assets that follow U.S. GAAP and use the same certified financial statements in Schedule M-3 reconciliation.

Even under the directive, taxpayers must retain underlying books and records supporting the computation.

100-Point R&D Tax Credit Preparer Readiness Scorecard

Suggested readiness bands

• 90–100: Ready to own defined recurring research-credit preparation with normal manager/specialist review.
• 82–89: Generally review-ready; targeted coaching remains in contract, software, base, or Section 174A areas.
• 72–81: Controlled preparation with checkpoints before qualification and method/election decisions are finalized.
• Below 72: Continue structured R&D-credit practice before independent ownership.

Override the numerical score for fabricated retrospective evidence, unsupported across-the-board wage percentages, materially incomplete business components, unreviewed funded-research contracts, foreign research treated as qualified, accidental Section 280C/election treatment, or a refund claim filed without the required component/activity information.

A 30/60/90-Day R&D Tax Credit Training Plan

Days 1–30: Teach qualification without dollar pressure

Give staff technical records for:

• One manufacturing process improvement
• one software feature
• one routine customer customization that should be excluded

Do not provide payroll until the staff member finishes the activity analysis.

Days 31–60: Add the cost bridge

Add:

• Employee-by-project records
• officer wages
• supplies
• two contractor agreements
• domestic/foreign research split
• Section 174A reconciliation
• regular and ASC computations

Days 61–90: Make the evidence imperfect

Add:

• One missing time record
• customer-funded development contract
• internal-use software
• controlled group
• acquired business component
• amended-return claim
• prior-year QRE inconsistency

Use Scenario-Based Training for Accountants so staff learn to say “this cost is not yet supportable” before a live credit is filed.

15 Realistic R&D Tax Credit Training Scenarios

1. The engineering department percentage

The CFO says all 14 engineers spend 80% of their time on R&D. Staff must test actual activities employee by employee instead of importing one executive estimate.

2. The successful project with no visible testing

A new product launched successfully, but the project file contains only final drawings. The learner must locate evidence of alternatives and experimentation rather than infer qualification from success.

3. The failed prototype

A prototype consumed $90,000 of material and was abandoned. Staff recognizes that failure can support experimentation but still tests whether the material cost is a qualified supply rather than depreciable property.

4. The custom customer request

A software company modifies an existing application for one customer’s reporting format. The learner distinguishes routine adaptation from a discrete technically uncertain improvement.

5. Shrink back to the qualifying subsystem

A manufacturing line contains mostly standard equipment but one new process-control subsystem required genuine experimentation. Staff applies shrink-back instead of claiming the entire line or rejecting the entire project.

6. The executive “research manager”

The CTO oversees five engineering managers but does not directly supervise individual experiments. Staff challenges whether all CTO wages are direct-supervision QREs.

7. The contractor owns the IP

A client pays a developer under a fixed-price agreement and gives the developer no meaningful rights in the resulting research. Staff identifies funded-research risk before taking 65% of the invoices.

8. The foreign development team

U.S. product managers work with programmers in Europe. Staff separates domestic qualified services from foreign research and also coordinates the foreign Section 174 treatment.

9. The book R&D account

The controller gives staff a $3 million R&D GL total. It includes patents, depreciation, market studies, foreign engineering, and product-launch costs. Staff builds a tax reconciliation rather than calling the GL account QREs.

10. The 80% confusion

A preparer believes that because Section G requires 80% of QREs by component, every employee with any research time can be treated as 100% qualified. The learner distinguishes the two separate 80% rules.

11. Section 280C discovered after filing

The tax team calculates a large credit but never discusses the reduced-credit election until after the original return is filed. Staff learns why election control belongs in the pre-filing checklist.

12. The ASC looks easy

The company has current QREs of $1 million, but prior-year QRE data was prepared under inconsistent definitions. Staff repairs the historical consistency before relying on the ASC calculation.

13. Section G top components do not match project records

The tax software has “Project 1, Project 2, Project 3,” while engineering uses product feature names. Staff creates stable component IDs and a crosswalk before filing.

14. The missed credit from two years ago

A company wants an amended refund claim but cannot identify business components or research activities beyond a consulting study percentage. The learner rebuilds required claim information and clearly identifies unsupported areas.

15. The startup payroll tax election

A young company has less than $5 million of current gross receipts but had predecessor gross receipts six years earlier. Staff tests the actual Section 41(h)(3) QSB definition rather than assuming startup status.

What CPA Firms Should Measure

Connect these measures to the firm’s Staff Accountant Competency Checklist, Accounting Onboarding KPIs, and Accounting Employee Development Plan.

Common R&D Tax Credit Training Mistakes

Mistake 1: Start with payroll

Staff calculate a potential benefit before proving qualified activity.

Mistake 2: Use one company-wide R&D narrative

The four-part test belongs at the business-component level.

Mistake 3: Confuse difficulty with technical uncertainty

A hard project is not automatically qualified research.

Mistake 4: Describe experimentation without alternatives

Boilerplate replaces actual tests, failures, and design changes.

Mistake 5: Claim all engineer wages

Job title is substituted for qualified services.

Mistake 6: Assume book R&D equals tax QREs

Financial accounting and Section 41 populations are different.

Mistake 7: Ignore the contract

Funded-research risk is missed.

Mistake 8: Ignore Section 174A

The credit and deduction/capitalization positions do not reconcile.

Mistake 9: Optimize ASC without fixing historical consistency

The calculation looks precise but the base data is not comparable.

Mistake 10: Reconstruct evidence after the IRS asks

Retrospective interviews are asked to replace records that should have been retained during the work.

Frequently Asked Questions About R&D Tax Credit Training

What is R&D tax credit training for accountants?

It is structured training that teaches accountants to identify qualified research by business component, document the four-part test and experimentation, identify exclusions, build qualified research expenses, reconcile Section 174A and Section 41, calculate Form 6765, and preserve evidence for review or examination.

What is Form 6765?

Form 6765 is used to calculate and claim the federal credit for increasing research activities, make the Section 280C reduced-credit election, and make the qualified-small-business payroll tax credit election.

What is the four-part test for the R&D tax credit?

Qualified research generally must satisfy the Section 174A/R&E foundation, be technological in nature, be intended to develop or improve a business component, and involve a process of experimentation relating to function, performance, reliability, or quality.

What is a business component?

A business component can be a product, process, computer software, technique, formula, or invention held for sale, lease, license, or use in the taxpayer’s trade or business.

Is Form 6765 Section G required in 2026?

For tax years beginning after 2025, current Form 6765 instructions generally require Section G unless an exception applies. Required filers generally report component information for at least 80% of total QREs, capped at the top 50 components.

What are the current Section G exceptions?

Current instructions include an exception for a Section 41(h)(3) qualified small business making the payroll tax credit election and an exception for certain original-return taxpayers with controlled-group QREs of $1.5 million or less and prior-three-year average annual gross receipts of $50 million or less.

What are qualified research expenses?

QREs generally include qualified in-house wages, supplies used in qualified research, certain computer rental/lease costs, and applicable percentages of contract research expenses.

Do all engineer wages qualify?

No. Qualification depends on what the employee actually did. Qualified services generally include conducting qualified research, directly supervising it at the first-line level, and directly supporting it.

What is the employee 80% rule?

If at least 80% of an employee’s services for the year are qualified services, the substantially-all wage rule can treat all services as qualified for this purpose. If less than 80%, the actual qualified portion is generally used.

Is the employee 80% rule the same as Section G’s 80% rule?

No. Section G’s 80%/Top 50 rule concerns how required filers report QREs by business component. The employee 80% rule concerns an individual’s qualified services.

How much contract research can qualify?

Current Form 6765 instructions generally use 65% for qualifying research performed by another person, 75% for certain qualified research consortium payments, and 100% for certain qualified energy research payments to specified organizations.

What is funded research?

Research can be excluded when another party funds it. Contract terms regarding payment risk and the taxpayer’s rights in the research are important to the analysis.

What changed with Section 174A?

P.L. 119-21 added Section 174A, generally allowing current deductions for domestic R&E expenditures paid or incurred in tax years beginning after 2024, with alternative capitalization/amortization options. Foreign R&E remains subject to separate 15-year amortization rules.

Are Section 174A expenses the same as Section 41 QREs?

No. The rules overlap, but the populations are not automatically identical. A reconciliation should bridge domestic R&E tax treatment to the narrower Section 41 QRE categories and qualification rules.

What is the Section 280C reduced-credit election?

It is an election that reduces the research credit and avoids the normal deduction/capital-account reduction mechanism. Under the current Form 6765, the regular-credit multiplier is 15.8% rather than 20%, and the ASC is multiplied by 79% when the reduced-credit election applies.

What is the Alternative Simplified Credit?

The ASC generally equals 14% of current QREs exceeding 50% of the average QREs for the prior three years. If the taxpayer had no QREs in any one of those prior years, the current form provides a 6% alternative computation.

What is the R&D payroll tax credit?

A qualifying small business can elect up to $500,000 of its research credit against qualifying payroll tax liability, subject to the Section 41(h) gross-receipts, age, controlled-group, timing, and other rules.

What information is required for an amended R&D credit refund claim?

Current IRS procedures require identification of the business components, research activities performed for each component, and total qualified wage, supply, and contract research expenses for the claim year. Additional details can be requested on examination.

What is the 45-day R&D refund-claim perfection period?

The IRS transition period currently gives taxpayers 45 days to perfect certain deficient research-credit refund claims before final rejection, and the IRS has extended that transition through January 10, 2027.

What documentation should support an R&D credit?

Useful support can include project authorizations, technical requirements, uncertainty statements, engineering drawings, test plans/results, prototypes, code records, project-management data, employee time/activity records, payroll, supply invoices, contracts, GL reconciliations, and Form 6765 workpapers.

How do you know when an accountant is review-ready for R&D credits?

A review-ready preparer can qualify activity by business component, explain the technical uncertainty and experimentation, identify excluded/funded/foreign research, trace QREs to qualified services and books, coordinate Section 174A/280C, calculate the available methods, complete Form 6765/Section G, and hand the reviewer an evidence-indexed file.

The Bottom Line

R&D tax credit training should not produce staff who know how to multiply a QRE total by a credit rate.

It should produce preparers who can prove why the QRE total exists.

Catalog the business component.

Record the technical uncertainty.

Evidence the experimentation.

Document the qualified purpose.

Identify exclusions.

Tie qualified activities to QREs.

Reconcile Section 174A and the books.

Evaluate the method and base.

Assemble Form 6765 and Section G.

Defend the file.

Capture evidence during the year.

That is CREDIT READY.

The staff accountant should know why an engineering payroll report is not an R&D credit study.

They should know why “we did not know if it would work” is weaker than a documented capability, method, or design uncertainty.

They should know why a failed prototype can strengthen the evidence file.

They should know why routine customer adaptation can be excluded even when engineers did the work.

They should know why an employee’s title does not qualify the wages.

They should know why two different 80% rules exist.

They should know why Section 174A deductions and Section 41 QREs need a bridge.

They should know why the Section 280C election belongs in the original-return workflow.

They should know why the 2026 Section G reporting architecture makes business-component discipline more important.

And they should know when contracts, internal-use software, controlled groups, foreign research, accounting methods, amended refund claims, or weak evidence make the issue too important to guess.

Qualify the activity.
Capture the evidence.
Tie the cost.
Then calculate the credit.

Protect Knowledge. Develop People. Scale the Firm.

To preparers who build the evidence before the benefit,
