I have completed my tax return and I have a balance due. How do I pay the tax liability

To pay your tax liability, the IRS offers several payment options:

1. Electronic Funds Withdrawal (EFW): You can authorize a direct debit from your bank account when you e-file your return. This option allows you to schedule the payment for a future date up to the due date of the return.
2. Electronic Federal Tax Payment System (EFTPS): You can use EFTPS to pay your taxes online or by phone. You need to enroll in EFTPS, which can be done online or by calling 800-555-4477.
3. Debit or Credit Card: You can pay your tax bill using a debit or credit card through an approved payment processor. This can be done online, by phone, or by mobile device. Note that there may be a convenience fee charged by the payment processor.
4. Check or Money Order: You can mail a check or money order made payable to the "United States Treasury." Include your name, address, daytime phone number, Social Security number (SSN), the tax year, and the form number on the check or money order. Mail it to the address listed in the instructions for your tax return.
5. Cash: You may be able to pay your taxes in cash at a participating retail store. Visit the IRS website for more information on this option.
6. Same-Day Wire Transfer: You can make a same-day wire transfer from your financial institution. Contact your financial institution for availability, cost, and cutoff times.

For more information on these payment options, visit the IRS website at IRS.gov/Payments.
