How to interpret this estimate
Federal regular income tax on taxable income after deductions.
Enter the amount in the currency shown and check the stated tax year. Use the input basis named on the form. Where the field calls for taxable income after deductions, establish those deductions separately. This calculator does not establish eligibility for a relief or credit.
Choose Single, Married filing jointly, Married filing separately or Head of household to use that status's implemented federal brackets. Filing status changes the brackets; it does not decide whether you qualify to file in that status. For the current 2026 tool, an example from the existing audit: 100,000 of taxable income with Married filing jointly gives 11,504 federal regular income tax before excluded items.
Excludes credits, alternative minimum tax, preferential capital-gain/dividend rates and other special rules.
