NerdWallet Tax Calculator review
A free web calculator for estimating federal tax or refund across two tax years.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
NerdWallet Tax Calculator is a free web tool for U.S. filers who want an estimate of their federal income tax bill or refund. It supports tax years 2025 and 2026 and lets users choose single, head of household, married filing separately, or married filing jointly. Inputs include gross income, age, deductions, tax withheld, and estimates for adjustments such as retirement contributions and tax credits. The result is an estimate based on federal tax brackets, not a state tax calculation or paycheck figure.
Its breadth of accepted income sources makes the calculator relevant beyond straightforward W-2 wages. It can account for 1099 income, tips, commission, interest, dividends, investments, rental income, retirement distributions, unemployment compensation, and Social Security benefits. Users can also enter 401(k), IRA, and other deductions, alongside tax credit estimates. That scope is useful for solo filers comparing a range of income and adjustment scenarios, while still requiring users to supply their own estimates; it is not presented as a full tax-filing service.
The main boundary is jurisdiction: the calculator explicitly excludes state income taxes, so anyone planning for total federal and state liability will need another resource for the state portion. It is a fit for a quick federal estimate across the supported filing statuses and tax years, especially when the goal is to understand a possible bill or refund. Filers seeking a state estimate, a paycheck calculation, or tax preparation rather than an estimator should choose a different tool for those needs.
