Calculate your quarterly estimated tax payments and avoid underpayment penalties — for any income type.

Step 1 of 3

Step 1: Filing Info & W-2 Income

Enter your filing status and any W-2 wage income with withholding. This is your baseline.

Filing Status

W-2 wages (annual, all jobs combined)

Federal income tax withheld (full year, all W-2s) ?Check your pay stub for federal tax withheld per period, multiply by total pay periods in the year.

Last year's total tax liability (Form 1040, Line 24) ?Used for the 100%/110% safe harbor calculation. If last year's AGI was over $150K ($75K MFS), the safe harbor is 110%.

Step 2: Non-Wage Income

Income not subject to W-2 withholding

Enter all income sources that don't have taxes automatically withheld. This is what creates the need for estimated payments.

Self-employment / freelance income (net profit)

Interest & dividends

Capital gains (net)

Rental income (net) ?Rental income minus expenses. Enter 0 if you have a net loss (losses may be limited by passive activity rules).

Retirement distributions (pensions, IRA, 401k) ?Taxable portion only. If withholding was taken from distributions, include that in Step 1's withholding field.

Other taxable income

Step 3: Deductions & Credits

These reduce your total tax liability and affect your quarterly payment amount.

Estimated itemized deductions (if more than standard) ?Only enter if you plan to itemize AND your total exceeds the standard deduction. Otherwise leave at 0.

Number of children under 17 (Child Tax Credit)

Other tax credits (education, energy, etc.)

Estimated payments already made this year
