No Tax on Overtime

Calculates the 2025-2028 federal deduction for qualified overtime pay under the One Big Beautiful Bill Act (P.L. 119-21, IRC 225) as IRS Schedule 1-A Part III does: the $12,500 cap ($25,000 joint), then $100 off per full $1,000 of MAGI over $150,000 ($300,000 joint). Only the FLSA half-time premium qualifies, so it converts hourly rate, overtime hours and multiplier (or total overtime pay) to the qualified amount; double time does not double it. Married filing separately gets $0. Figures copied from irs.gov in Oct 2026.

Calculates the 2025-2028 federal deduction for qualified tips under the One Big Beautiful Bill Act (P.L. 119-21, IRC 224) as IRS Schedule 1-A Part II does: a $25,000 cap per return for every filing status, then $100 off per full $1,000 of MAGI over $150,000 ($300,000 joint). Self-employed tips count only up to that business's net income. Married filing separately gets $0. Figures copied from irs.gov in Oct 2026.

Estimates the federal income tax saved in 2025-2028 by the One Big Beautiful Bill Act overtime, tips and senior deductions combined. It applies each deduction's cap and phase-out, then runs taxable income through the IRS bracket tables for that year (Rev. Proc. 2024-40 for 2025, Rev. Proc. 2025-32 for 2026) before and after. 2027-2028 brackets are not published yet, so it uses 2026 and says so. Federal income tax only.
