Where to Mail Your IRS Payment and What to Include
Mail your IRS payment to the address printed on your tax notice or bill, not to the IRS office in your city
The IRS uses different mailing addresses depending on what you owe and where you live. The correct address appears on any notice or bill the IRS sent you — that is the safest place to look first. If you do not have a notice, the IRS publishes a list of payment addresses by state on its website, and you can also call the IRS at 1-800-829-1040 to confirm the right address before you mail anything.
Do not send payment to a local IRS office or a tax preparation business. Money sent to the wrong address delays processing, creates confusion about which tax year or account the payment covers, and can result in penalties or interest charges while the IRS sorts it out. Using the official address takes the same amount of time to mail but protects your record.
Key Takeaways
- The mailing address for your IRS payment is printed on any notice or bill the IRS sent you — use that address first.
- If you do not have a notice, the IRS publishes state-by-state payment addresses on IRS.gov, or you can call 1-800-829-1040 to confirm.
- Include your name, address, Social Security number or employer identification number, tax year, and form type on the check or money order itself.
- Mail payments at least one week before the due date to account for postal delays, and keep a copy of what you sent for your records.
- If you cannot pay in full, the IRS offers payment plans and other options that may reduce penalties and interest.
How to prepare your payment for mailing
Write a check or money order payable to "United States Treasury." On the front of the check or money order, write your Social Security number or employer identification number (EIN), the tax year, and the form type — for example, "2023 Form 1040" or "2024 Form 1120-S." This information tells the IRS which account and tax year the payment belongs to.
Include a payment voucher if you have one. If the IRS sent you a bill or notice, it usually includes a voucher designed to be mailed with your payment. The voucher has your account number and tax information already printed on it, which speeds up processing. If you do not have a voucher, write the information directly on the check or money order instead — the IRS will still process it, but it may take longer.
Do not send cash, and do not send a personal check from a business account unless you are the sole proprietor. If you are paying on behalf of a business, use a business check or money order and include the EIN on the payment itself.
Payment addresses by region
The IRS maintains separate mailing addresses for different states and types of returns. The address you need depends on where you live and what form you filed. For example, if you live in California and filed Form 1040, your address is different from someone in Texas who filed the same form.
The fastest way to find your address is to look at any notice or bill the IRS sent you — the return address is printed at the top. If you do not have a notice, visit IRS.gov and search for "where to file" or "payment addresses," or call 1-800-829-1040 and have your Social Security number or EIN ready. The IRS representative can give you the exact address in seconds and confirm it is current.
Do not rely on addresses you find through a search engine or a tax software company, because addresses change and outdated information can cause delays. The IRS website and the phone line are the official sources.
Timing and proof of payment
Mail your payment at least one week before the due date. The IRS processes payments based on the postmark date, not the date it arrives, so a payment postmarked before the deadline is on time even if it arrives after. However, postal delays happen, and mailing early protects you if your envelope is delayed.
Keep a copy of the check or money order number, the amount, the date you mailed it, and the address you sent it to. If the IRS later says it did not receive your payment, you will have proof of what you sent and when. You can also request a return receipt from the post office when you mail the payment — this costs a few dollars but gives you a signed record that the envelope was delivered.
If you pay by check, do not stop payment on the check after you mail it. The IRS may process it weeks or months later, and stopping payment will create a problem with your account.
When to use payment plans instead of mailing a lump sum
If you cannot pay the full amount by the due date, do not skip the payment and hope the IRS forgets. Instead, contact the IRS before the deadline to set up a payment plan. The IRS offers short-term plans (up to 180 days) and long-term installment agreements that let you pay over months or years.
A payment plan stops or reduces the failure-to-pay penalty and can lower interest charges compared to paying late with no plan in place. You can request a plan by phone at 1-800-829-1040, through your IRS online account, or by mail. If you set up a plan before the deadline, the IRS is more likely to approve it quickly and with fewer fees.
Even if you have a payment plan, you still need to file your tax return on time. The plan covers the balance you owe, not the filing deadline.
Electronic payment as an alternative to mailing
If you want to avoid mailing altogether, the IRS accepts electronic payments through its website. You can pay by bank transfer (ACH), debit card, or credit card. Electronic payments are processed faster than mailed checks, and you get a confirmation number immediately.
To pay electronically, visit IRS.gov and look for "payment options" or "pay now." You will need your Social Security number or EIN, the amount you owe, and your bank account or card information. The IRS does not charge a fee for ACH transfers, but credit card and debit card payments include a processing fee charged by a third-party payment processor — typically 1 to 2 percent of the amount you pay.
Electronic payment is especially useful if you are close to the deadline or if you want a same-day confirmation that the IRS received your payment. If you mail a check, you will not know for certain that it arrived until the IRS posts it to your account, which can take weeks.
What happens if you mail to the wrong address
If your payment reaches the wrong IRS office or a non-IRS address, it will either be returned to you or forwarded to the correct location. Either way, processing is delayed. During that delay, interest and penalties continue to accrue on your account.
If you realize you mailed to the wrong address before the IRS processes it, call 1-800-829-1040 immediately and explain the situation. The IRS may be able to intercept the payment or adjust your account to reflect the payment date you intended. If the payment has already been processed to the wrong account, the IRS can transfer it, but this takes time and requires documentation.
To avoid this problem, always double-check the address on your notice or bill before you seal the envelope, and use the IRS website or phone line if you are unsure.
Frequently Asked Questions
Can I send my payment to a tax professional or accountant instead of the IRS?
No. Your tax professional can prepare your return and advise you on payment options, but they cannot receive your IRS payment on your behalf. Money sent to a tax office will not reach the IRS and will not be credited to your account. Always mail directly to the IRS address on your notice or bill.
What if I do not know my Social Security number or EIN to write on the check?
Your Social Security number is on your tax return and any notice the IRS sent you. If you cannot find it, call the IRS at 1-800-829-1040 and they can confirm it. Do not mail a payment without this information — the IRS will not know which account to credit it to, and processing will be delayed.
Is it safe to mail a check to the IRS?
Mailing a check is a standard and safe way to pay the IRS. The check is made out to "United States Treasury," not to an individual, so it cannot be cashed by someone else. Write your account information on the check itself so the IRS can match it to your account even if the envelope is damaged. If you are concerned about mail theft, use a payment plan or electronic payment instead.
How long does it take the IRS to process a mailed payment?
The IRS typically posts a mailed payment to your account within two to four weeks of receiving it. During this time, interest continues to accrue on the unpaid balance. If you need faster processing, use electronic payment through IRS.gov, which is posted the same day or the next business day.
What if the address on my notice is different from the address on the IRS website?
Use the address on your notice. The notice is specific to your account and tax situation, so it is more accurate than a general address list. If you have questions about why the addresses differ, call 1-800-829-1040 before you mail.
