What Is Income Tax Provision Training for Staff Accountants?

Income tax provision training develops a staff accountant’s ability to translate financial-statement income, tax-law differences, tax attributes, and tax uncertainty into current and deferred income tax expense, balance-sheet accounts, and disclosures under ASC 740.

The tax return and the tax provision are related, but they are not the same workpaper.

The return asks:

• What taxable income exists under enacted tax law?
• What tax is payable or refundable?
• What deductions, credits, carryforwards, and elections apply?

The provision asks those questions and:

• Which book-versus-tax differences reverse in future periods?
• What future taxable or deductible amounts will those reversals create?
• Will deferred tax assets be realized?
• Are any tax positions uncertain under ASC 740?
• Why does the effective tax rate differ from the statutory rate?
• Where should the tax effect be presented in the financial statements?

This capability builds naturally on C Corporation Tax Training for Staff Accountants, Tax Workpaper Training for Staff Accountants, Tax Return Review Process, Professional Skepticism Training for Junior Accountants, and Scenario-Based Training for Accountants.

Why ASC 740 Is a Judgment-Development Topic

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 development problem: staff often learn how to populate a tax-provision template before they learn what each provision balance means.

ASC 740 exposes that problem quickly.

A spreadsheet can multiply a temporary difference by 21%. It cannot prove the difference is actually temporary, determine when it reverses, decide whether a different enacted rate applies, or conclude whether the resulting deferred tax asset will be realized.

A software package can generate a rate reconciliation. It cannot explain whether the rate driver is permanent, state, foreign, credit-related, valuation-allowance-related, or simply a bad current-tax calculation.

“The tax provision template rolls” is not the capability.

“Book income, current tax, deferred tax, valuation, uncertainty, tax expense, and disclosure reconcile through source evidence” is.

What Is Current in ASC 740 in 2026?

The ASC 740 framework itself is mature, but 2026 is a meaningful implementation year because disclosure requirements and tax laws have changed while tax departments continue to operate under compressed close deadlines.

Chart: Where Income Tax Provision Judgment Concentrates

SkillAbility training heat map—not a FASB ranking. Actual complexity depends on jurisdictions, tax attributes, ownership structure, profitability history, credits, compensation, acquisitions, and tax positions.

The PROVISION READY Framework

P — Pin Down Pretax Book Income and the Taxing Jurisdictions

Every provision should start from a financial-reporting amount that is controlled.

Start with closed or clearly identified pretax book income

Staff should document:

• Entity/legal taxpayer
• financial-statement period
• pretax book income from continuing operations
• domestic vs. foreign pretax income where applicable
• discontinued operations, OCI, or equity items with tax effects
• consolidation/top-side entries affecting pretax income

A provision should not quietly start from an outdated management P&L while the financial statements have moved.

Build the jurisdiction map before the tax calculation

ASC 740 applies to domestic and foreign federal/national, state, local, and similar taxes based on income.

The provision file should identify:

• Tax-paying entities
• federal/national jurisdictions
• states/localities
• foreign jurisdictions
• consolidated/fiscal unity groups where applicable
• tax rates and enacted-rate changes

R + V — Build the Current Tax Provision From Book Income to Taxable Income

The current provision estimates taxes payable or refundable under enacted tax law for the current period.

Staff should not confuse a current tax workpaper with a completed tax return. The provision may require estimates for information that will be finalized later, but each estimate should be supportable.

Return-to-provision is a control, not cleanup

When the tax return is filed, compare the as-filed return to the prior-year current provision.

Typical RTP differences include:

• Final depreciation
• bonus/accrual deductibility
• state apportionment
• R&D credits
• meals/other permanent items
• tax-return elections
• final taxable compensation

Each RTP item should answer:

1. Was last year’s provision estimate reasonable?
2. Does the item affect current tax only, deferred tax, or both?
3. Does the item indicate a recurring process/control weakness?

Current-tax payable should reconcile to cash tax activity

At year-end:

Do not leave estimated payments, extensions, refunds, or state payments outside the provision reconciliation.

O — Permanent Differences, Temporary Differences, and Tax Attributes

Permanent differences

Permanent differences affect taxable income or book income without creating a future reversal.

Depending on applicable tax law, examples can include:

• Certain nondeductible expenses
• certain tax-exempt income
• some credits or special deductions that affect the effective tax rate differently from a temporary difference

Permanent differences typically drive the effective tax rate but do not create a DTA or DTL.

Temporary differences

Temporary differences exist when the financial-statement carrying amount of an asset or liability differs from its tax basis and the difference is expected to create taxable or deductible amounts in future years.

Tax attributes

Tax attributes can create future tax benefits independent of a balance-sheet carrying amount.

Examples include:

• Net operating loss carryforwards
• tax-credit carryforwards
• capital-loss carryforwards

They require separate expiration, limitation, and realization analysis.

I — Build Deferred Tax Assets and Liabilities From the Balance Sheet

ASC 740 follows a balance-sheet approach to deferred taxes.

The staff accountant should begin with:

Then determine whether recovery or settlement creates future taxable or deductible amounts.

Core deferred-tax sequence

1. Identify the book carrying amount.
2. Determine tax basis.
3. Calculate temporary difference.
4. Determine taxable vs. deductible direction.
5. Determine expected reversal pattern.
6. Apply the enacted tax rate expected to apply when reversal occurs.
7. Consider valuation allowance for DTAs.

Do not create deferred tax from trial-balance labels alone

“Accrued expenses = DTA” is not always sufficient.

Ask:

• Is the liability deductible when paid?
• Is it already deductible?
• Is any portion permanently nondeductible?
• Does a limitation affect future deductibility?

Deferred taxes are noncurrent on the balance sheet

Under current U.S. GAAP, DTAs and DTLs are presented as noncurrent. For a particular tax-paying component within a particular jurisdiction, DTAs, DTLs, and related valuation allowances are offset and presented as a single noncurrent amount; amounts from different tax-paying components or jurisdictions are not simply netted together.

Reversal Patterns and Scheduling: Why “Difference × Rate” Can Be Incomplete

Many straightforward temporary differences can be measured without a complex scheduling model. Others require staff to understand when and how the difference reverses.

Scheduling matters when:

• Tax rates differ across future periods
• different character rates could apply
• NOL or credit utilization depends on timing
• valuation-allowance realization depends on future taxable income
• tax law limits deductions in particular years
• outside-basis or foreign tax considerations apply

Build the rollforward

A provision becomes easier to review when the current-year movement in deferred tax can be traced to originations, reversals, rate changes, acquisitions, valuation allowance, and other specific causes.

S — Valuation Allowance: Build Evidence, Not Optimism

ASC 740 requires a valuation allowance when, based on the weight of available evidence, it is more likely than not—more than 50% likely—that some portion or all of a DTA will not be realized.

This is one of the highest-judgment areas in the provision.

Potential sources of taxable income

The analysis can consider applicable sources such as:

• Future reversals of existing taxable temporary differences
• future taxable income exclusive of reversing temporary differences and carryforwards
• taxable income in prior carryback years if permitted
• qualifying tax-planning strategies

Positive and negative evidence

Negative evidence can include:

• Cumulative losses in recent years
• history of expiring carryforwards
• losses expected in early future periods
• material unresolved business risks

Positive evidence can include:

• Strong taxable income history
• existing taxable temporary differences that reverse in the right periods
• firm sales backlog or objectively supportable evidence of future profitability
• implemented tax-planning strategies that meet ASC 740 requirements

Objective evidence generally carries more weight

A forecast saying “next year will be profitable” is weaker evidence when the entity has a recent cumulative loss and the forecast depends on aggressive growth assumptions.

Worked valuation-allowance screen

Assume an entity has a $500,000 gross DTA related to NOLs and deductible differences.

After scheduling reversals, expiration periods, and supportable future taxable income, management concludes that only $180,000 is more likely than not to be realized.

The staff accountant’s work is not “calculate $320,000.” It is to organize the evidence so the reviewer can see why $180,000 is supportable.

I — Uncertain Tax Positions: Recognition Comes Before Measurement

ASC 740’s uncertain-tax-position model has two distinct steps.

Step 1 — Recognition

A tax benefit cannot be recognized unless it is more likely than not that the tax position would be sustained on examination based solely on technical merits, assuming the taxing authority has full knowledge of all relevant information.

Step 2 — Measurement

If the recognition threshold is met, the recognized benefit is the largest amount of benefit that is greater than 50% likely to be realized upon settlement.

Worked UTP measurement example

Assume the full tax benefit is $100,000 and the recognition threshold has been met.

The largest benefit with a cumulative likelihood greater than 50% is $80,000.

Staff should not independently conclude complex technical tax positions beyond their competence. Their development goal is to know how to identify, inventory, support, roll forward, and escalate them.

O — Enacted Tax-Law and Rate Changes

ASC 740 measures deferred tax using enacted tax laws and rates expected to apply when temporary differences reverse.

The effect of a change in tax laws or rates is recognized at the date of enactment.

Staff law-change control

For every provision period, maintain:

• Jurisdiction
• law or rate change
• enactment date
• effective date
• current-tax impact
• deferred-tax remeasurement impact
• ETR impact
• disclosure impact

Do not use proposed rates because they look likely

U.S. GAAP does not use a “substantively enacted” concept for deferred-tax measurement. The tax law or rate must meet the U.S. GAAP enactment standard.

Rate changes can create discrete provision effects

If a rate changes from 21% to 24% for a DTL expected to reverse after the new rate becomes effective, the DTL is remeasured. The remeasurement effect is recognized in the period that includes enactment, subject to applicable allocation guidance.

R — Effective Tax Rate Reconciliation: Explain the Provision in One Bridge

The rate reconciliation explains why reported tax differs from expected tax at the applicable statutory rate.

Typical rate drivers

• State and local taxes, net of applicable federal effects
• foreign rate differentials
• nondeductible expenses
• tax-exempt income
• tax credits
• valuation-allowance changes
• uncertain tax positions
• enacted-law changes
• return-to-provision adjustments
• share-based compensation

Simple federal rate-reconciliation example

Pretax income: $2,000,000.

Expected tax at 21%:

Permanent differences:

• $100,000 nondeductible expense → +$21,000 tax effect
• $40,000 tax-exempt income → −$8,400 tax effect

Temporary differences affect the mix between current and deferred tax, but absent other effects they do not by themselves create a permanent ETR difference over the life of the item.

E — ASU 2023-09: Why 2026 Changes Private-Company Provision Training

ASU 2023-09 significantly increases the usefulness and granularity of annual income-tax disclosures.

For public business entities, the amendments became effective for annual periods beginning after December 15, 2024.

For entities other than public business entities, the amendments are effective for annual periods beginning after December 15, 2025.

That makes calendar-year 2026 the first required annual reporting year for many private companies.

Income taxes paid — all entities

All entities subject to the requirements disclose income taxes paid, net of refunds received, disaggregated annually by:

• Federal/national
• state
• foreign

They also separately disclose individual jurisdictions whose net income taxes paid meet the quantitative threshold of 5% of total income taxes paid, subject to materiality.

Pretax income and tax expense disaggregation — all entities

Annual disclosures also include:

• Income or loss from continuing operations before income tax expense, disaggregated between domestic and foreign
• income tax expense or benefit from continuing operations, disaggregated by federal/national, state, and foreign

Rate reconciliation — PBEs

Public business entities provide a tabular rate reconciliation using both percentages and reporting-currency amounts, with specified categories and additional disaggregation for qualifying items.

Rate reconciliation — non-PBEs

Entities other than PBEs are not required to present the same quantitative table. Instead, they qualitatively disclose the nature and effect of specified categories and individual jurisdictions that create significant differences between the statutory and effective tax rate. A non-PBE may still present a quantitative reconciliation if it provides better information.

The training implication

Do not wait until footnote drafting to ask:

• Which jurisdiction received each cash tax payment?
• Which ETR item belongs to which category?
• Which foreign jurisdiction drove a material rate difference?
• What was domestic vs. foreign pretax income?
• How was federal/state/foreign tax expense generated?

A — Intraperiod Tax Allocation: Where Does the Tax Effect Belong?

ASC 740 requires annual income tax expense or benefit to be allocated among appropriate financial-statement components.

These can include:

• Continuing operations
• discontinued operations
• other comprehensive income
• items charged or credited directly to shareholders’ equity

The allocation model is commonly described as a “with-and-without” approach and can be technically challenging.

Staff should recognize the trigger

If the current year contains:

• Discontinued operations
• AOCI/OCI activity with tax effects
• direct-to-equity items
• major valuation-allowance changes

the tax provision may require more than a single tax-expense line in continuing operations.

Interim Tax Provision: Annual Effective Rate Plus Discrete Items

Interim ASC 740 accounting is not simply “annual tax divided by four.”

For ordinary income or loss, entities generally estimate the annual effective tax rate expected for the full fiscal year and apply that rate to year-to-date ordinary income or loss.

Certain items are recognized discretely in the period in which they occur rather than included in the annual rate.

Examples can include specific effects of:

• Enacted tax-law changes
• certain valuation-allowance changes
• significant unusual or infrequently occurring items
• some share-based compensation tax effects

Interim provision training should be a second-stage skill after staff can prepare a sound annual provision.

N — State, Foreign, Tax Credits, and Share-Based Compensation

State provision

State income-tax accounting can require:

• Apportionment
• state-specific rates
• NOLs/credits
• separate-company vs. combined filing rules
• federal benefit of state taxes

For multistate provision work, connect the state-tax schedule to the firm’s multistate tax training and jurisdiction-specific workpapers rather than treating state tax as a single blended percentage.

Foreign provision

Foreign jurisdictions can add:

• different statutory rates
• local deferred-tax rules within the U.S. GAAP model
• foreign tax credits
• withholding taxes
• outside-basis issues
• Pillar Two / global minimum tax considerations

These areas should be escalated when outside the staff accountant’s defined competence.

Tax credits

Credits can affect current tax, deferred tax, ETR, carryforwards, and valuation allowance. The provision should distinguish a credit from a deduction and identify expiration and limitation rules.

Share-based compensation

Book compensation cost and tax deductions can differ in amount and timing. Share-based tax effects can create deferred taxes and discrete tax effects that require specific ASC 740/718 analysis.

A — Assemble the Provision Journal Entry and Balance-Sheet Presentation

A complete provision should reconcile:

• Current tax expense/benefit
• deferred tax expense/benefit
• valuation allowance
• uncertain tax positions
• income tax payable/receivable
• net deferred-tax balances by jurisdiction/tax-paying component
• tax expense allocated outside continuing operations

Conceptual provision entry

Deferred-tax balance-sheet presentation

All deferred tax assets and liabilities are classified as noncurrent. For a tax-paying component within a tax jurisdiction, DTAs, DTLs, and valuation allowance are offset; different tax-paying components and different jurisdictions are not simply netted together.

Worked Example: From Pretax Book Income to Current and Deferred Federal Tax

Assume a calendar-year C corporation has:

• Pretax book income: $2,000,000
• Nondeductible permanent expense: $100,000
• Tax-exempt permanent income: $40,000
• Tax depreciation exceeds book depreciation by $300,000
• Accrued bonus deductible next year: $150,000
• Allowance expense deductible when written off: $80,000
• Federal enacted tax rate used in the example: 21%

Step 1 — estimated current taxable income

Step 2 — current federal tax

Step 3 — ending deferred taxes

Depreciation taxable temporary difference:

Accrued bonus deductible temporary difference:

Allowance deductible temporary difference:

Assuming these are new differences and no valuation allowance or other deferred items exist, deferred tax expense is $14,700.

Step 4 — total federal tax provision

Step 5 — effective tax rate

The ETR reconciles from 21% because the $100,000 nondeductible permanent item adds $21,000 of tax expense while the $40,000 tax-exempt permanent item reduces tax expense by $8,400.

Change one fact: the $150,000 bonus is permanently nondeductible

It no longer creates a DTA. Instead, it becomes a permanent ETR item. The current taxable-income effect remains, but the deferred-tax conclusion changes.

Change one fact: the entity has loss history and cannot support realization of the $48,300 DTA

The valuation-allowance analysis becomes necessary and can increase tax expense.

Change one fact: a tax rate change is enacted before year-end

The deferred tax balances need to be remeasured using the enacted rate expected to apply when the differences reverse.

100-Point ASC 740 Provision Readiness Scorecard

Suggested readiness bands

• 90–100: Ready to own defined recurring domestic provisions with normal manager/technical review.
• 82–89: Generally review-ready; targeted coaching remains in valuation, UTP, or disclosure.
• 72–81: Controlled ownership with checkpoints before deferred tax, VA, UTP, and ETR conclusions.
• Below 72: Continue structured ASC 740 practice before independent ownership.

Override the numerical score for fabricated tax support, intentional rate manipulation, unsupported release of valuation allowance, hidden uncertain positions, use of non-enacted tax rates, or provision plugs that do not reconcile to current/deferred tax support.

A 30/60/90-Day Income Tax Provision Training Plan

15 Realistic Income Tax Provision Training Scenarios

1. The temporary difference that is actually permanent

Staff creates a DTA for an accrued expense that tax law will never allow as a deduction. The learner reclassifies the item as a permanent difference and updates the ETR.

2. The return-to-provision difference ignored in the current year

The filed return differs materially from last year’s provision. Staff identifies whether the true-up changes current tax, deferred tax, or both.

3. The 21% rate used after an enacted future-rate change

A future enacted rate applies when a temporary difference will reverse. Staff remeasures deferred tax rather than leaving the old rate because the current-year return still uses it.

4. The DTA supported only by an optimistic forecast

The company has recent cumulative losses, but management’s forecast shows a rapid turnaround. Staff organizes objective negative evidence before relying on subjective positive evidence.

5. The NOL that expires before income arrives

Future taxable income is projected, but the NOL expires too early. Staff schedules expiration rather than treating all future profit as realization support.

6. The DTL that is ignored in the VA analysis

A taxable temporary difference reverses in a way that may provide a source of taxable income for DTA realization. Staff incorporates the relevant reversal pattern.

7. The uncertain position that “has always been filed this way”

Staff learns that historical filing practice does not replace technical-merit analysis under ASC 740.

8. The UTP measured using the single most likely outcome

The learner applies the largest-benefit-greater-than-50%-likely measurement model instead of a “best estimate” approach.

9. The state tax provision built with last year’s apportionment

Operations shifted materially among states. Staff refreshes the state provision rather than rolling old percentages forward.

10. The effective rate that jumps with no explanation

Staff builds an ETR bridge and discovers a mix of state tax, permanent compensation, RTP, and valuation-allowance changes.

11. The tax effect placed entirely in continuing operations

The year includes OCI and a discontinued operation. Staff identifies the intraperiod allocation issue for review.

12. The private company using last year’s tax footnote

For a calendar-year 2026 non-PBE, staff identifies the ASU 2023-09 disclosure changes and captures taxes-paid jurisdiction data.

13. The jurisdictional tax payments nobody tracked

Cash taxes are in one GL account without federal/state/foreign detail. Staff reconstructs the data and designs a next-year control.

14. The interim provision calculated as one-fourth of annual tax

Staff replaces the shortcut with estimated annual effective-rate logic plus discrete items.

15. The tax expense plug

The current provision and deferred rollforward produce one total while the P&L target says another. Staff resolves the difference instead of adjusting “other tax expense.”

Common Income Tax Provision Training Mistakes

Mistake 1: Start from taxable income instead of book income

The provision loses the bridge to the financial statements and ETR.

Mistake 2: Treat every book-tax difference as temporary

Permanent items get DTAs/DTLs that should not exist.

Mistake 3: Build deferred taxes from prior-year labels

The tax basis, deductibility, or enacted rate may have changed.

Mistake 4: Treat valuation allowance as a forecast exercise only

Objective negative and positive evidence is not properly weighted.

Mistake 5: Use probability of audit in UTP recognition

ASC 740 assumes the position is examined with full knowledge of the relevant facts.

Mistake 6: Measure a UTP using the most likely single outcome

The ASC 740 measurement model uses the largest benefit that is greater than 50% likely to be realized.

Mistake 7: Update deferred tax for proposed legislation

U.S. GAAP requires enacted-law treatment.

Mistake 8: Force the ETR to a target

The rate reconciliation should explain tax expense, not determine it.

Mistake 9: Build the tax disclosure after the provision is done

ASU 2023-09 requires data that should be controlled throughout the provision process.

Mistake 10: Put every difficult tax item into “other”

Aggregation hides the economics and weakens both review and disclosure.

Frequently Asked Questions About Income Tax Provision Training

What is ASC 740?

ASC 740 is the U.S. GAAP Topic governing accounting for income taxes, including current income taxes, deferred taxes, uncertain tax positions, valuation allowances, intraperiod allocation, interim reporting, presentation, and disclosure.

What is an income tax provision?

An income tax provision is the financial-statement accounting for current and deferred income taxes for a reporting period, including applicable valuation, uncertainty, allocation, and disclosure requirements.

What is the difference between current and deferred tax expense?

Current tax expense reflects taxes payable or refundable for the current period under tax law. Deferred tax expense or benefit reflects changes in the future tax consequences of temporary differences and tax attributes, subject to valuation and other ASC 740 rules.

What is a permanent difference?

A permanent difference affects book income and taxable income differently without reversing in a future period. It generally affects the effective tax rate but does not create a deferred tax asset or liability.

What is a temporary difference?

A temporary difference is a difference between a financial-statement carrying amount and tax basis that will create taxable or deductible amounts when the related asset is recovered or liability is settled.

What is a deferred tax asset?

A DTA represents a future tax benefit from deductible temporary differences, loss carryforwards, credit carryforwards, or similar items, subject to the ASC 740 realization/valuation-allowance assessment.

What is a deferred tax liability?

A DTL represents future taxable amounts expected from taxable temporary differences.

Are deferred tax assets and liabilities current or noncurrent?

Under U.S. GAAP, deferred tax assets and liabilities are classified as noncurrent.

When is a valuation allowance required?

A valuation allowance is required when, based on the weight of available evidence, it is more likely than not that some portion or all of a DTA will not be realized.

What does “more likely than not” mean for valuation allowance?

ASC 740 describes it as a likelihood greater than 50%.

What is an uncertain tax position?

An uncertain tax position is a tax position for which the recognition and/or measurement of the tax benefit requires analysis under ASC 740’s uncertainty model.

What is the recognition threshold for an uncertain tax position?

The benefit can be recognized only if it is more likely than not that the position will be sustained on examination based solely on technical merits, assuming the taxing authority has full knowledge of all relevant information.

How is a recognized uncertain tax position measured?

The recognized amount is the largest tax benefit that is greater than 50% likely to be realized upon settlement.

When are tax-law changes recognized under ASC 740?

The effect of a change in tax law or tax rate is recognized at the date of enactment under U.S. GAAP.

What is the effective tax rate?

The effective tax rate is generally income tax expense or benefit from continuing operations divided by pretax income or loss from continuing operations, subject to the entity’s reporting facts.

What does the rate reconciliation explain?

It explains why reported income tax expense or benefit differs from the tax expected at the applicable statutory rate.

What changed under ASU 2023-09?

ASU 2023-09 enhances annual income-tax disclosures, including the rate reconciliation, income taxes paid by federal/state/foreign and significant individual jurisdictions, and disaggregation of domestic/foreign pretax income and federal/state/foreign tax expense.

When does ASU 2023-09 apply to private companies?

For entities other than public business entities, the amendments are effective for annual periods beginning after December 15, 2025. Therefore, calendar-year 2026 is a key first-adoption year for many private entities.

What is intraperiod tax allocation?

Intraperiod allocation is the process of allocating total tax expense or benefit among continuing operations and other financial-statement components such as discontinued operations, OCI, and items charged or credited directly to equity.

How does interim tax provision accounting differ from annual provision accounting?

Interim reporting generally applies an estimated annual effective tax rate to year-to-date ordinary income or loss, while specified discrete items are recognized in the period in which they occur.

What is return-to-provision?

Return-to-provision compares the prior-year provision estimate with the filed tax return and records the accounting effect of differences while identifying recurring estimation or process issues.

How do you know when a staff accountant is review-ready for ASC 740?

A review-ready staff accountant can reconcile pretax book income to current tax, build and roll deferred taxes, distinguish permanent/temporary/attribute items, support valuation-allowance evidence, identify uncertain positions for escalation, explain the ETR, prepare the tax journal entry, and produce disclosure support without unexplained plugs.

The Bottom Line

Income tax provision training should not produce staff who can only make tax expense equal a target rate.

It should produce accountants who can defend every layer of the provision.

Pin down pretax book income.

Reconcile current taxable income.

Separate permanent, temporary, and tax-attribute items.

Build current tax from enacted law.

Build deferred tax from book and tax basis.

Understand reversals.

Evaluate DTA realization from evidence.

Identify uncertain tax positions.

Track enacted tax-law changes.

Explain the effective tax rate.

Allocate tax to the right financial-statement category.

Build disclosure data into the provision process.

Reconcile the journal entry to the balance sheet and footnote.

That is PROVISION READY.

Protect Knowledge. Develop People. Scale the Firm.

To staff who can explain the tax provision before review has to reconstruct it,
