TaxCaster review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

TaxCaster is a free, browser-based calculator from TurboTax for individuals who want a quick estimate of a federal income tax refund or balance due. It supports the 2025 tax year and asks for filing status and dependent information, along with income, deductions, credits, and taxes already paid. The available filing statuses include Single, Married Filing Jointly, Married Filing Separately, Qualifying Surviving Spouse, and Head of Household. Its focus is a federal estimate rather than preparing or filing a return.

The calculator accounts for income categories associated with W-2, 1099, and other income statements, and includes both federal income tax withheld and estimated tax payments. Deductions and credits also feed into the estimate, making it useful for a preliminary view of how these inputs affect a possible refund or balance due. TaxCaster is web-based and free, which suits someone who wants to check an estimate without choosing a paid plan or downloading an app.

Its narrow scope is the main trade-off: results cover federal income tax only, not state refunds or state tax owed. The result is for planning and is neither a filed tax return nor an official IRS determination, so it should not be treated as a final filing result. TaxCaster is a fit for solo U.S. filers who need a fast federal estimate; someone seeking a state calculation or a broader tax-preparation process should look elsewhere. The TaxCaster mobile app is no longer available for download.
