The new tax deductions, calculated properly.
The One Big Beautiful Bill Act created new federal deductions for overtime premium, tips, car loan interest and changed the 1099 reporting thresholds, for tax years 2025 to 2028, all claimed on Schedule 1-A. Every calculator here follows the IRS rules line by line, including the parts most calculators get wrong: only the overtime premium counts, tips are capped per return, and each deduction phases out differently.

New here? Read the guide first
The plain-English guide to the new deductions explains all four deductions on Schedule 1-A in one place, who each one covers and where each number comes from. For quick figures, the caps and phase-outs reference puts every cap, threshold and phase-out rate in one table, and the deductions timeline shows when each rule starts, changes and ends.
These deductions run for tax years 2025 to 2028 and then sunset. They lower your taxable income, not your tax bill directly, and every result on this site is an estimate, not tax advice.
