In most cases, you must pay estimated tax for 2026 if both of the following apply.
You expect to owe at least $1,000 (checked November 8, 2026) in tax for 2026, after subtracting your withholding and refundable credits.
You expect your withholding and refundable credits to be less than the smaller of: 90% of the tax to be shown on your 2026 tax return, or 100% of the tax shown on your 2025 tax return. Your 2025 tax return must cover all 12 months.
These percentages may be different if you have income from farming or fishing or are a higher income taxpayer.
You don't have to pay estimated tax for 2026 if you were a U.S. citizen or resident alien for all of 2025 and you had no tax liability for the full 12-month 2025 tax year. You had no tax liability for 2025 if your total tax was zero or you didn't have to file an income tax return.
What to bring and attach to Form 1040-ES
Complete and send in the voucher only if you are making a payment by check or money order.
If you choose to mail in your payment, there is a separate estimated tax payment voucher for each due date. The due date is shown in the upper-right corner.
Make your check or money order payable to “United States Treasury.” Don't send cash.
To help process your payment accurately, enter the amount on the right side of the check like this: $ XXX.XX. Don't use dashes or lines (for example, don't enter “$ XXX-” or “$ XXX xx/100”).
Enter “2026 Form 1040-ES” and your SSN on your check or money order. If you are filing a joint estimated tax payment voucher, enter the SSN that you will show first on your joint return.
Enclose, but don't staple or attach, your payment with the estimated tax payment voucher.
