Formula
Taxable income = max(0, ordinary income − verified adjustments − eligible deductions). Apply each marginal rate to its income band. Subtract eligible nonrefundable credits up to modeled income tax; subtract entered refundable credits and payments for a modeled balance.
Worked example
For a single U.S. resident in 2026 with 60,000 ordinary income, the basic 16,100 standard deduction, and no other adjustments or credits, taxable income is 43,900. Regular federal income tax is 1,240 + 31,500 × 12% = 5,020, excluding other taxes.
What the result means
The U.S. preset covers 2026 regular federal ordinary-income tax. Other countries require your verified marginal bands. Eligibility, phaseouts, AMT, capital-gains rates, self-employment tax, NIIT, and automatic state/local rules are outside this estimate.
