The tax provision (also called the income tax provision or ASC 740 provision) is the intersection of tax law and financial reporting. It's one of the most complex areas of accounting, requiring expertise in both taxation and financial reporting standards.
What Is a Tax Provision?
The tax provision determines:
- Current tax expense: Tax owed on this year's taxable income
- Deferred tax expense: Tax effects of temporary differences between book and tax
- Total income tax expense: Reported on the income statement
- Effective tax rate: Total tax expense ÷ pre-tax income
Components
Current Tax
- Calculate taxable income (book income ± permanent and temporary differences)
- Apply applicable tax rates (federal, state, international)
- Consider credits, NOLs, and other adjustments
- Result: Current tax payable on the balance sheet
Deferred Tax
- Identify temporary differences between book and tax basis of assets/liabilities
- Classify as deferred tax assets (DTA) or deferred tax liabilities (DTL)
- Evaluate need for valuation allowance on DTAs
- Result: Net deferred tax asset or liability on the balance sheet
Common Temporary Differences
| Item | Book vs. Tax | Creates |
|---|---|---|
| Depreciation | Accelerated tax depreciation | DTL |
| Bad debt reserve | Accrual vs. direct write-off | DTA |
| Revenue recognition | Different timing | DTA or DTL |
| Compensation accruals | Accrued vs. paid | DTA |
| Net operating losses | Carryforward benefit | DTA |
| Inventory reserves | Book reserves not deductible until realized | DTA |
Tax Provision Process
Quarterly (Interim Provisions)
- Estimate annual effective tax rate (AETR)
- Apply AETR to year-to-date pre-tax income
- Adjust for discrete items
- Calculate interim tax expense
Annual (Year-End Provision)
- Calculate actual taxable income
- Prepare detailed current and deferred tax computations
- Assess uncertain tax positions (ASC 740-10)
- Evaluate valuation allowances
- Prepare rate reconciliation
- Draft financial statement disclosures
ASC 740-10: Uncertain Tax Positions
For positions taken on tax returns that may not be sustained:
- Recognition threshold: "More likely than not" standard (>50%)
- Measurement: Largest amount with >50% likelihood of being sustained
- Disclosure: Nature and amount of uncertain positions
- Interest and penalties: Accrued as appropriate
