Terms of use

By using this site you agree to these terms. If you do not, please do not use it.

General information, not advice

This site is general information, not tax advice. Figures are estimates and may not reflect the final IRS guidance for the tax year. Confirm your situation with a qualified tax professional or the IRS before filing.

Nothing here creates a professional relationship of any kind. The site does not know your full circumstances, and the calculators only see the figures you give them.

Estimates

Every figure the calculators produce is an estimate. They cover federal income tax only; they do not compute your tax liability, and they do not account for state tax, credits, other deductions or anything else on your return. Tax law and IRS guidance change, and a figure that was right when it was checked can be overtaken. Each tool shows when its figures were last verified and links the source.

You are responsible for what you put on your return. Confirm any figure against the official IRS forms and instructions, or with a qualified tax professional, before you rely on it.

No warranty

The site is provided “as is” and “as available”, without warranties of any kind, express or implied, including accuracy, completeness, fitness for a particular purpose and uninterrupted availability.

Limitation of liability

To the fullest extent the law allows, OBBBA Deductions is not liable for any loss or damage arising from your use of, or reliance on, this site — including tax, interest or penalties assessed on a return.

Acceptable use

Use the site for its purpose. Do not try to disrupt it, overload it, or get around its security.

Content

The text and design of this site belong to OBBBA Deductions. You are welcome to quote short passages with a link back. Figures taken from statutes and IRS publications are public information.

Links to the IRS and other sites are provided for reference. Those sites are not under this site's control.

Changes
