Slice of incomeRateTax on this slice

Tax is figured in slices. Each slice of your income is taxed at its own rate — moving over a line never raises the tax on the dollars below it.

This is an estimate of federal income tax only. It uses the IRS figures for 2026 (Revenue Procedure 2025-32). It does not include state tax, payroll tax, or any credits beyond the deductions you entered, and it is not a promise of a refund or an amount owed. Your actual return can differ.
