United States Tax Calculators

Free, localized tax planning tools updated for the 2026 financial year in United States.

The 2026 tax year is the first full year of the One Big Beautiful Bill Act's new personal deductions, and that is exactly what these tools price: tip income and overtime premium deductions, the $6,000 senior bonus, US-built auto loan interest, and the combined effect of claiming several at once. Alongside them sit the two calculators for when things go wrong or get logged, the automatic penalty waiver under FS-2026-12 and the rare split-year mileage rates of 72.5 and 76 cents. Every tool runs the actual 2026 IRS brackets and phase-outs, so the answers move the way your Form 1040 will.
