How to send money to the IRS

The IRS does not accept payments mailed to its office addresses. Instead, you send payments to a lockbox — a secure processing center run by a bank on behalf of the IRS. The lockbox address depends on where you live and what type of payment you are making. Using the wrong address delays processing and can trigger penalties, so matching your state and payment type to the correct lockbox is the first step.

The IRS maintains a full list of lockbox addresses on its website organized by state and payment category. You can also pay electronically through the IRS website without mailing anything. Electronic payment is faster, leaves a clear record, and avoids the risk of a check getting lost in the mail.

Key Takeaways

  • The IRS does not accept payments at its office addresses; you must use a lockbox address that matches your state and payment type.
  • Electronic payment through IRS Direct Pay, the Electronic Federal Tax Payment System (EFTPS), or a credit card is faster and creates an immediate record.
  • If you mail a check, include your Social Security number or Employer Identification Number on the check itself, and allow 2 to 3 weeks for processing.
  • The correct lockbox address is listed on your tax notice, on the IRS website by state, or by calling the IRS at 1-800-829-1040.

Electronic payment methods

IRS Direct Pay is the fastest option if you have a bank account. You log in at irs.gov, enter your tax information and bank details, and the payment is deducted on the date you choose. There is no fee, and you receive a confirmation number immediately. The IRS processes the payment within one business day.

EFTPS (Electronic Federal Tax Payment System) is used mainly by businesses and self-employed people who make regular payments. You enroll once, then schedule payments online or by phone. EFTPS is free and works with checking or savings accounts. Payments must be scheduled at least one business day in advance.

Credit or debit card payments can be made through third-party processors approved by the IRS. Common processors include PayPal, Stripe, and others listed on irs.gov. These processors charge a fee — usually 1.87% to 2.35% of the payment amount — but the fee is separate from your tax payment and does not reduce what you owe.

Mailing a check or money order

If you mail a payment, write your Social Security number (or Employer Identification Number for a business) on the front of the check or money order. Do not send cash. Include a payment voucher if you have one — the Form 1040-ES for individual estimated tax, or the form that came with your tax notice.

The lockbox address depends on your state. For example, if you live in California and are paying individual income tax, the address is different from the address for someone in Texas. The IRS website lists all lockbox addresses by state at irs.gov/payments. You can also find the correct address on any tax notice the IRS sent you.

Mail takes 7 to 10 business days to reach a lockbox, and the IRS allows 2 to 3 weeks from the date you mail it to process the payment. If your payment is due on a specific date, mail it at least 3 weeks early. If you miss the deadline, the IRS will charge interest and penalties on the unpaid amount, even if your check was in transit.

What happens if you send payment to the wrong address

If you mail a check to an IRS office instead of the lockbox, the office will forward it, but this adds 2 to 4 weeks to processing time. During that delay, the IRS may record you as unpaid and begin charging interest and penalties. Once the check arrives at the correct lockbox and clears, you can request that penalties be removed, but you will still owe interest.

To avoid this, always verify the lockbox address before mailing. The safest approach is to use electronic payment, which processes the same day and leaves no room for routing errors.

Payments for specific situations

If you are paying a balance from a prior year tax return, use the lockbox address for your state and payment type. If you are paying estimated tax as a self-employed person, use the Form 1040-ES voucher and the address listed on it. If you are paying payroll taxes as a business, use EFTPS or the lockbox address for employment tax payments, which is different from the individual income tax lockbox.

If you received a notice from the IRS about a specific amount owed, that notice includes the correct lockbox address and a payment voucher. Using the voucher ensures your payment is matched to your account correctly. If you have lost the notice, call the IRS at 1-800-829-1040 to confirm the address and your account balance before sending payment.

Tracking your payment

Electronic payments can be tracked immediately. IRS Direct Pay and EFTPS give you a confirmation number on the day you schedule the payment. You can log back in to check the status or print your confirmation for your records.

For mailed checks, there is no tracking until the payment clears. The IRS typically updates your account 2 to 3 weeks after the check is received. If you need to confirm that a mailed payment was received, call the IRS at 1-800-829-1040 with your Social Security number and the check amount and date. Have your check number ready if you have it.

Frequently Asked Questions

Can I pay the IRS directly from my bank?

Yes, through EFTPS or by setting up a bill payment through your bank's online system. If you use your bank's bill pay feature, make sure you enter the correct lockbox address for your state. Electronic payment through irs.gov is simpler because the IRS provides the routing information.

What if I cannot pay the full amount I owe?

Send what you can. The IRS will charge interest on the unpaid balance, but paying something stops the interest from growing as quickly. If you owe a large amount, you can set up a payment plan through the IRS website or by calling 1-800-829-1040. A payment plan lets you pay in monthly installments.

Do I need to include a cover letter with my mailed payment?

No. The lockbox processes thousands of payments daily and does not read letters. Include only your Social Security number on the check and the payment voucher from your tax notice. If you need to explain something about your payment, call the IRS after the payment clears.

How long does it take for the IRS to show my payment on my account?

Electronic payments show within one business day. Mailed checks take 2 to 3 weeks from the date you mail them. If more than 3 weeks have passed and your account still shows unpaid, call the IRS with your check number and date to confirm receipt.
