Terms of use and disclaimer

Not tax advice

The calculators and guides on Ballpark Tax give estimates and general information about US federal tax rules. They are not legal, tax or financial advice, and they do not take your full situation into account. State and local taxes are not included. Before you file a return or make a payment that matters, confirm the figures with a CPA or an enrolled agent.

Accuracy

Figures are taken from IRS publications for the tax year shown and the calculations are covered by automated tests, but tax rules change and mistakes are possible. Ballpark Tax makes no guarantee that any estimate is complete or correct for you, and is not liable for decisions made using it. If you find an error, please report it.
