Mail Form 940 to the IRS Service Center for Your State

When you file Form 940 without a payment, you send it to the IRS Service Center that handles your state, not to the address you would use if payment were enclosed. The IRS maintains separate mailing addresses for returns with and without payment because returns without payment go through a different processing track.

The address you use depends on where your business is located. Each state has a designated IRS Service Center, and using the wrong one delays processing. The IRS publishes the complete list of addresses in the Form 940 instructions, updated annually.

You can also find your state's address on the IRS website by searching "Form 940 mailing address" plus your state name, or by calling the IRS Business and Specialty Tax Line at 800-829-4933. Have your state ready when you call.

Key Takeaways

  • Form 940 without payment goes to a different IRS Service Center address than Form 940 with payment, so check the current instructions before mailing.
  • The correct address depends on your business location state, and using the wrong address delays processing by weeks.
  • The Form 940 instructions booklet includes a table of all state mailing addresses, updated each year.
  • If you are unsure which address to use, call the IRS at 800-829-4933 rather than guessing, because correcting a misdirected return takes longer than a phone call.

How to Find Your State's Correct Mailing Address

The Form 940 instructions PDF contains a table titled "Where to File" or "Addresses for Mailing Your Return." This table lists every state and its corresponding IRS Service Center address. Download the current year's instructions from IRS.gov or request them by phone.

The address changes occasionally when the IRS consolidates or relocates service centers, so do not use an address from last year's filing. Even if your state's address has not changed, the instructions you receive with your Form 940 package will always have the current address.

If you file electronically through tax software or a tax professional, the software routes your return to the correct location automatically. Paper filers must verify the address themselves.

What Happens If You Mail to the Wrong Address

If you send Form 940 to a service center that does not handle your state, the IRS will eventually forward it to the correct location. This forwarding process adds two to four weeks to processing time. Your return will not be marked as received until it reaches the correct service center, which can cause confusion if you are tracking status.

A misdirected return may also miss internal deadlines if it arrives late in the processing cycle. The IRS does not send a notice telling you that your return was misdirected; you discover the problem only when you check your account online or call to ask about status.

To avoid this, spend two minutes confirming the address before you seal the envelope. The cost of a phone call to verify is far lower than the cost of delayed processing.

Mailing Without Payment vs. Paying Separately

You can file Form 940 without payment for several reasons: you may owe no tax, you may have already paid through deposits during the year, or you may plan to pay later. In all cases, the mailing address for a return without payment differs from the address you would use if payment were enclosed.

If you do owe tax and plan to pay it later, you can still mail the return to the no-payment address and send payment separately. Payment can be made through the IRS Direct Pay system, by credit or debit card through an approved payment processor, or by check mailed to a different address. The return and payment do not have to arrive at the same time or place.

Some businesses mail the return first and then pay within a few days. Others pay first and file the return later. The IRS processes both sequences correctly as long as the return reaches the correct service center.

Using the IRS Address Lookup Tool

The IRS website includes an interactive tool where you enter your state and filing status, and it returns the correct mailing address. This tool is updated in real time when addresses change, so it is more current than a printed instructions booklet.

To use it, go to IRS.gov, search for "Where to File," and select the result for Form 940. The tool will ask you to confirm your state and whether you are enclosing payment. Select "No" for payment, and the tool will display the address.

Print or write down the address before you prepare your envelope. Do not rely on memory or an old filing record.

Tracking Your Return After Mailing

Once you mail Form 940 without payment, you can track its receipt through your IRS online account. Create an account at IRS.gov if you do not already have one. After you file, log in and select "View Your Tax Account" to see when the IRS received and processed your return.

Processing typically takes four to six weeks from the date the IRS receives your return. If you mailed to the correct address and your return is complete, you should see it posted to your account within that window. If six weeks pass and your return does not appear, contact the IRS to confirm it arrived.

The IRS does not send a paper receipt for mailed returns. Your online account is the only confirmation that the return was received and processed.

Frequently Asked Questions

Can I mail Form 940 to the same address I use for other tax forms?

No. Form 940 has its own mailing address, which is different from the address for Form 941 (quarterly payroll tax) or Form 1040 (income tax). Each form type routes to a different processing center. Using the wrong address delays processing.

What if I mail Form 940 to the payment address by mistake?

The IRS will forward it to the correct location, but this adds two to four weeks to processing time. Your return will not show as received in your account until it reaches the correct service center. If you realize the mistake before mailing, open the envelope and use the correct address instead.

Do I need to include a cover letter or note when I mail Form 940 without payment?

No. The form itself is sufficient. Do not include a letter explaining why you are not paying, as it may slow processing. If you need to communicate something to the IRS, do so after the return is processed through your online account or by calling the Business and Specialty Tax Line.

Is there a way to confirm the address is correct before I mail?

Yes. Call the IRS Business and Specialty Tax Line at 800-829-4933 and give them your state. They will confirm the current mailing address. You can also use the IRS website lookup tool, which is updated in real time when addresses change.

What if my business operates in multiple states?

Mail Form 940 to the service center for the state where your business is incorporated or where your principal place of business is located. If you have questions about which state to use, call the IRS at 800-829-4933 before mailing.
