Disclaimer

The calculators and guides explain federal tax rules in general terms. They do not know your situation. Nothing here is tax, legal, accounting, or investment advice, and reading it does not create a professional relationship with anyone.

The calculators use 2026 federal figures and simplified state rules. They do not model every credit, phase-out, or state provision, and they cannot account for anything unusual in your return. Treat every result as a rough estimate. Your real tax can be higher or lower, sometimes by a lot.

Figures are for the 2026 tax year and come from IRS releases. Congress and the IRS change the rules, sometimes late in the year and sometimes retroactively, and this site may lag behind.

Before you contribute, convert, sell, or claim anything based on what you read here, run it past a CPA, enrolled agent, or tax attorney who knows your situation. You are responsible for your own return.

Some pages link to outside sites, such as the IRS, for reference. We do not control those sites and are not responsible for their content.
