Quarterly Estimated Tax Calculator
Calculate quarterly estimated tax payments for self-employed individuals
About this calculator
The Quarterly Estimated Tax Calculator helps self-employed individuals, freelancers, and business owners determine how much they need to pay in quarterly estimated taxes to the IRS. Since self-employed people don't have taxes automatically withheld from paychecks, they must make these payments four times per year to avoid penalties. This calculator ensures you pay the right amount based on your expected annual income, deductions, and tax obligations, helping you stay compliant with IRS requirements and avoid underpayment penalties.
How to use
Enter your expected annual income, business deductions, and filing status into the calculator. The tool will compute your estimated annual tax liability and divide it by four to show your quarterly payment amount. Make these payments by the IRS quarterly due dates: January 15, April 15, June 15, and September 15.
