The deadline to file your 2025 federal income tax return is April 15, 2026. This calculator helps you estimate your tax liability or refund before that deadline so you can plan accordingly.

This calculator uses the official 2025 tax brackets, standard deductions, and credits released by the IRS, making it highly accurate for most common tax situations. However, it provides estimates only and doesn’t cover every possible tax scenario. For complex situations involving investments, business income, or special deductions, consult a tax professional.

The calculator uses the 2025 IRS tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The income ranges for each bracket vary by filing status (Single, Married Filing Jointly, etc.). You can view the specific brackets applied to your calculation in the results section.

For 2025, the standard deductions are: $15,000 for Single filers, $30,000 for Married Filing Jointly, and $22,500 for Head of Household. Additional amounts are available for taxpayers 65+ or blind. The calculator automatically applies these based on your inputs.
