How we work

RefundTally is an independent publisher, not a tax preparer and not the Internal Revenue Service. We turn published IRS rate tables into transparent browser tools, cite every source, and keep your inputs on your device. If an IRS page and this site ever disagree, the official page wins. Part of the dollarfinch.com family — see also Year-End Moves and NewDeduct.

Frequently asked questions

Is this the official IRS refund estimator?

No. RefundTally is an independent publisher. The Internal Revenue Service publishes its own tools and Free File options at IRS.gov. If an official page and this site disagree, the official page wins.

Which tax year do these calculators cover?

Tax year 2026, which you generally file in early 2027. Amounts come from IRS Revenue Procedure 2025-32 and IRS news release IR-2025-103 (9 October 2025).

Is a calculator result tax advice or a filed return?

No. Results are educational estimates from the figures you enter and a simplified federal worksheet. They do not include every form, credit or state tax. Confirm with current IRS instructions or a qualified professional, or file for free through IRS Free File if you qualify.
