Where to Mail Installment Agreement Payments

If you owe a balance to the IRS and you cannot pay the full amount owed, you may be eligible for an installment agreement. This agreement allows you to make payments over time to resolve your tax debt.

Once you have set up your installment agreement, you will need to send payments to the IRS. But where do you send them? Here’s what you need to know.

Where to Mail Installment Agreement Payments

The address you should use to mail your payments will depend on where you live and the form you used to set up your installment agreement. If you used Form 9465 (Installment Agreement Request) to set up your agreement, you should mail your payments to the address listed on the form.

If you did not use Form 9465, you can find the address to use by visiting the IRS website. There, you can enter your state and zip code to find the address you should use.

You can also make your payments online or by phone if you prefer. To make payments online, visit the IRS website and use the Direct Pay or Online Payment Agreement tool. To make payments by phone, call the toll-free number listed on your installment agreement paperwork.

Tips for Mailing Installment Agreement Payments

To ensure your payments are processed correctly and on time, follow these tips:

1. Always include your name, address, and Social Security number or taxpayer identification number on your payment.

2. Make checks or money orders payable to the United States Treasury. Do not send cash.

3. Use the correct payment voucher or coupon when mailing your payment. This helps the IRS to apply your payment correctly.

4. Mail your payment early to allow time for processing. This is especially important if your payment due date falls on a weekend or holiday.

5. Consider sending your payment by certified mail or with a return receipt requested. This provides proof of mailing and delivery.
