Standard vs Itemized Deduction Calculator
Compare two deduction paths for tax year 2026 using your eligible expenses. Results estimate regular federal income tax before credits and alternative minimum tax (AMT). They are not a complete tax return or a recommendation about how to file.
Last reviewed: — calculation, assumptions and page content.
Which situations does this comparison cover?
Use this model for a Single, Married Filing Jointly or Head of Household return when every filer is a U.S. resident, under 65, not blind, and cannot be claimed as someone else's dependent. Income is taxed at ordinary rates; there are no foreign or U.S. territory income exclusions, net operating loss carrybacks, qualified disaster-loss additions to the standard deduction, qualified business income deductions, or Schedule 1-A deductions for tips, overtime, car-loan interest or seniors.
The comparison excludes tax credits, AMT, capital-gains and qualified-dividend rates, special tax computations such as kiddie tax (Form 8615), state taxes and payroll taxes. Those can change your final tax. Cash charitable gifts must be current-year gifts to eligible public charities, with no carryovers, noncash gifts, donor-advised funds or supporting organizations. Gifts above 60% of AGI are outside this model.
Enter Your Details
Enter annual dollar amounts from $0 to $100,000,000, with up to two decimal places. Enter zero where an expense does not apply.
Annual income after above-the-line adjustments. With no foreign or U.S. territory income exclusions in this model, AGI also equals SALT modified AGI.
Your Itemizable Expenses
Enter only the deductible amount after mortgage-debt and use-of-funds limits. This model does not determine that eligibility.
Eligible property taxes plus state/local income taxes or general sales taxes, not both. The 2026 cap starts at $40,400 and phases down above $505,000 MAGI, to a $10,000 floor.
Qualified current-year cash gifts described above. The model applies the 0.5% AGI floor for itemizing and the separate $1,000/$2,000 nonitemizer limit.
Enter eligible expenses paid with after-tax funds and not reimbursed. Only the amount above 7.5% of AGI is deductible.
Amounts already eligible for Schedule A after their separate limits. Exclude amounts entered above, qualified disaster losses that increase the standard deduction, business expenses, IRA contributions and Schedule 1-A deductions.

Things to Know
Essential concepts for understanding your results
Tax FundamentalsHow does the federal tax system work?
Federal income tax uses progressive brackets: each layer of taxable income has its own rate, and the thresholds depend on filing status. Deductions lower taxable income; they are not dollar-for-dollar tax credits. The comparison calculates each path across the 2026 brackets rather than multiplying a deduction difference by one assumed rate.
Estimate ScopeHow does this differ from a full tax return?
This estimate starts with adjusted gross income, not gross wages or take-home pay. It compares regular federal income tax before credits and AMT. Withholding, payroll taxes, state taxes, capital-gain rates, qualified dividends and deductions outside the stated model can change the amount you ultimately owe or receive as a refund.
Compare CarefullyWhat should you check before choosing a deduction?
Keep records supporting eligible expenses and review both deduction paths. In 2026, eligible cash gifts can reduce taxable income even when taking the standard deduction. Itemizers face a charitable floor and, at high incomes, an overall itemized-deduction limitation. A larger raw expense total does not necessarily produce lower tax after those rules. Use the IRS worksheets for a full eligibility review.
2026 Standard Deduction Amounts
| Single | $16,100 |
| Married Filing Jointly | $32,200 |
| Head of Household | $24,150 |
2026 deduction limits
The SALT limit for the supported filing statuses starts at $40,400, falls by 30% of modified AGI above $505,000, and has a $10,000 floor. Eligible medical expenses must exceed 7.5% of AGI. Eligible itemized charitable gifts must exceed 0.5% of AGI.
After those limits, the overall itemized deduction can be reduced by the exact statutory fraction 2/37. Its income threshold is applied before subtracting itemized deductions. Calculations keep full precision; displayed amounts round to cents. This estimate uses rate schedules, so it can differ from return tax tables and final-return rounding.
Compare the Two Deduction Paths
Compare your own eligible amounts and tax results, using the same income and filing status.
| Component | Standard path | Itemized path |
|---|---|---|
| Base deduction | Filing-status standard deduction | Eligible Schedule A expenses |
| Eligible cash gifts | Separate $1,000 limit; $2,000 for MFJ | Amount above 0.5% of AGI, within supported limits |
| High-income itemized limit | Does not reduce the base standard deduction | Applied after expense-specific limits |
