There are several different ways to pay your tax bill in TurboTax.

1. Direct debit (free)
2. Credit or debit card (convenience fee)
3. Check or money order (free except for postage)
4. IRS Installment Agreement (this may be free or have a fee, depending on your circumstance)
5. Cash (at a retail partner)

You can pay for your taxes with your credit/debit card through a third-party payment processor. The processor charges a convenience fee.

If you're e-filing, choose Charge my credit card when we ask how you want to pay your federal taxes.

If you're paper-filing, you won't see a credit/debit option, but you can do this instead:

1. In TurboTax, select Pay by check when asked how you want to pay your taxes
2. Follow the instructions to print a paper copy of your return
   • Throw out the 1040-V voucher that prints out. You won't need it
3. Go to the IRS Pay Your Taxes by Debit or Credit Card site, choose a payment processor, and pay your tax bill there
