The calculators
- No tax on tips calculator — your qualified tips, the $25,000 cap, the MAGI phase-out, and your estimated tax saved (2025–2028, IRC §224)
- No tax on overtime calculator — only the FLSA premium “half” counts; see your deduction up to $12,500 / $25,000 joint (IRC §225)
- Self-employment tax calculator — the 15.3% broken down, the deductible half, and a quarterly estimated-payment schedule with due dates
- Paycheck calculator — salary or hourly pay → federal withholding estimate, Social Security, Medicare, and take-home per pay period
Why these exist: the One Big Beautiful Bill Act created the tips and overtime deductions for tax years 2025 through 2028, and most summaries get the fine print wrong — the cap is per return, only the overtime premium qualifies, and the deduction shrinks $100 for every $1,000 of income over $150,000 ($300,000 joint). These tools run the actual rules, with the phase-out math shown step by step.
How every tool on this page is built
Each calculator states its sources on the page: IRS Revenue Procedure 2025-32 for 2026 brackets and standard deductions, Revenue Procedure 2024-40 as increased by the new law for 2025, the SSA's 2026 COLA Fact Sheet for the wage base, and Internal Revenue Code §§224, 225, 1401 and 1402 for the deduction and self-employment rules. Each page shows a worked example you can check by hand, and each carries the same honest limit: these are estimators, not tax advice — your return has facts no four-input calculator can see.
