Not professional tax advice

The Service provides tax calculation software and does not constitute tax, legal, accounting, or financial advice. USA Taxes is not a Certified Public Accountant (CPA) firm, Enrolled Agent (EA), or law firm. Information provided by the Service should not be used as a substitute for advice from a qualified tax professional.

For complex tax situations, IRS audits, tax planning, or legal questions, please consult a licensed tax professional. Self-Employed plan users receive optional CPA review as part of the service; this review is performed by independent licensed CPAs and is not a guarantee of accuracy.

Calculation accuracy

USA Taxes uses tax brackets and rules from the IRS Revenue Procedure 2024-40 (federal) and official state tax tables for tax year 2025. State tax calculations for the following states use approximated formulas and should be reviewed by a CPA: AL, AR, CT, DE, IA, KS, LA, MO, MS, NE, NM, ND, OH, OK, RI, VT, WV. All state calculations are estimates only.

Federal calculations are performed using exact IRS bracket logic but do not handle every edge case (e.g. Alternative Minimum Tax for high-income filers, certain investment scenarios, foreign earned income exclusion). If you have a complex tax situation, please verify your return with a licensed professional.
