How much federal tax will I owe?

Enter annual wages, filing status, and deductions for an estimate based on 2026 US federal brackets. The result shows total tax, effective rate, and marginal bracket on taxable income — useful for planning, not for filing a return. State and local taxes are not included.

Standard vs itemized?

The calculator uses the larger of your standard deduction or itemized total when estimating taxable income. Itemizing helps when mortgage interest, charitable gifts, and other eligible deductions exceed the standard amount for your filing status, tax year, and country rules.

Enter traditional 401(k) or IRA contributions to reduce taxable income in the estimate. Roth contributions do not reduce current taxable income. Pre-tax retirement savings can shift you into a lower marginal bracket depending on income, filing status, and other deductions.

No — this is an illustrative estimate only. Credits, AMT, NIIT, and state taxes may be omitted or simplified. IRS rules change by year. Consult a CPA or qualified tax professional before filing or making decisions based on these numbers.
