How this calculator works
Subtract the additional deduction from taxable income, flooring the result at zero, and compare progressive tax before and after. Enter only a deduction you are entitled to claim; the tool does not determine eligibility.
Worked example
For a single filer with $60,000 taxable income, a further $10,000 eligible deduction reduces tax from $7,912 to $5,752, saving $2,160.
What this estimate includes
A deduction reduces taxable income; a credit reduces tax. The calculation excludes credit changes, payroll and state taxes, and deduction limits.
2026 rules and sources
Rates, thresholds, standard deductions and child-credit amounts use IRS Revenue Procedure 2025-32. See the 2026 federal bracket tables for all filing statuses. Read the full assumptions and sources.
