If you’re at risk for an underpayment penalty next year, we'll automatically calculate quarterly estimated tax payments and prepare vouchers (Form 1040-ES) for you to print. You're not required to make estimated tax payments; we're just suggesting it based on the info in your return. If you feel they're not needed for next year's taxes, you can shred them.
If you want to add these forms to your return yourself, follow these instructions.
Mail your payment along with the corresponding 1040-ES voucher to the IRS address listed on the voucher. Quarterly payment due dates are printed on each voucher.
Additional estimated tax payment options, including direct debit, credit card, cash, and wire transfer, are available at the IRS Payment website.
You also have the option when you file your return to apply some or all of your refund to your estimated tax payments for the coming tax year.
If you want to enter estimated taxes you've already paid into your tax return, follow these instructions.
