Find the Right IRS Address for Your Payment Voucher
Use the Check or Money Order Mailing Address Based on Your State
When you pay by check or money order, the destination address depends on where you live and which IRS service center serves your area. The IRS directs taxpayers to one of two regional addresses based on state residency to streamline processing.
Each voucher or coupon on your estimated tax voucher must include the correct address, your name, SSN or EIN, tax year, and the payment amount so your payment can be applied accurately without delays.
Using the wrong address can redirect your payment, increasing processing time and raising the risk of underpayment penalties, so verify the line for your state before you mail.
How to Pay Electronically for Accuracy and Speed
Direct Pay and EFW for Real-Time Confirmation
Direct Pay through IRS.gov lets you pay directly from your bank account on the payment due date, while Electronic Funds Withdrawal allows you to schedule a withdrawal when you e-file Form 1040-ES. Both options provide immediate confirmation, reducing the need to mail vouchers and lowering lost payment risk.
Electronic options create a digital record, including payment confirmation numbers and timestamps, which helps you resolve disputes quickly if the IRS system shows a delay. For taxpayers who miss the postmark deadline, electronic payment is the safest way to prove timely filing.
EFTPS for Scheduling and Managing Multiple Payments
The Electronic Federal Tax Payment System is ideal if you want to schedule payments in advance, track all federal tax payments in one dashboard, and receive alerts before each quarterly due date. You can schedule checks or electronic withdrawals so you do not have to remember each deadline manually.
Key Steps to Mail Your Federal Estimated Tax Payment Correctly
Prepare, Address, Send, and Confirm
- Complete the correct estimated tax voucher with the tax year, your SSN or EIN, and the exact amount.

Plan and Protect Your Estimated Tax Payments
Choosing the right mailing address and payment method helps you avoid penalties, confirm delivery, and keep clear records for audits. Combine electronic options for most payments with careful mail handling only when necessary.

- Verify the IRS address for your state each tax year using official instructions.
- Always send checks via certified mail and retain proof of delivery.
- Match all details on your voucher, including name, SSN or EIN, and tax year.

FAQ
Reader questions
Which address should I use if I live in California and am mailing my voucher with a check?
If you are a California resident mailing a voucher with a check or money order, send it to the IRS address designated for California residents listed in the current year’s Form 1040-ES instructions to ensure proper routing and faster processing.
Can I mail a credit card payment with a voucher, and which address should I use?
Do not mail credit card numbers on your voucher. Use an online or phone payment option authorized by the IRS, or pay electronically through Direct Pay or EFW. If you must mail a check for another reason, use the check-only address for your state, not a general P.O. Box.
What should I do if the IRS address has changed or the online tools show a different mailing address?
Always check the current address on the official IRS.gov Payment Options page or the latest Form 1040-ES instructions before mailing, because the IRS updates addresses for efficiency and may retire old service center locations.
How can I prove I mailed my payment on time if the IRS says they did not receive it?
Use certified or registered mail with a delivery confirmation receipt, keep a copy of the voucher and check, and send your payment at least five business days before the due date so you have verifiable proof of timely mailing.
