Tax Simulations

Practice real tax situations step by step. Build a tax return and watch the actual math, all from the same verified tax tables our calculators use. For learning, not tax advice.

Every number comes from the same verified 2026 federal tax tables that power our calculators, so what you see is exactly right. Nothing you type is stored, and there is never a sign-up.

These are for learning and are not tax advice. For your own return, talk to an IRS registered tax preparer.

Looking for something faster? Try the tax games or test yourself with a tax quiz.

For general education only, not tax advice. Covers federal income tax and leaves out some items (state tax, some phase-outs) to stay clear. Rules and figures can change.
