The fastest way to update your business address with the IRS

You can change your business address with the IRS by filing Form 8822-B, which takes about 10 minutes to complete and mail. The IRS processes address changes within 30 days, though you should allow extra time for mail delivery. If your business is a sole proprietorship, you may instead file Form 1040-X (amended return) or use the IRS online account portal if you have one set up.

The method you use depends on your business structure. Corporations, partnerships, and LLCs file Form 8822-B. Sole proprietors can use Form 8822-B as well, but some find it simpler to report the change on their next tax return. If you have an IRS online account through Business Services Online or the IRS e-services portal, you can update your address directly without filing a form—this is the fastest option if you already have login credentials.

Key Takeaways

  • Form 8822-B is the standard form for changing a business address and works for corporations, partnerships, LLCs, and sole proprietors.
  • If you have an IRS online account, you can update your address in the portal without mailing any paperwork.
  • Mail Form 8822-B to the IRS address listed on the form itself, which varies by state.
  • The IRS typically processes address changes within 30 days, but mail delivery can add one to two weeks.
  • Update your address with your state tax agency separately—the IRS and state systems do not automatically sync.

Filing Form 8822-B by mail

Form 8822-B is a one-page form that asks for your business name, Employer Identification Number (EIN), old address, and new address. You can read it free from IRS.gov or request a copy by calling the IRS at 1-800-829-3676. Fill in all required fields in black or blue ink, sign and date the form, and include your daytime phone number so the IRS can contact you if there are questions.

Mail the completed form to the IRS address shown on the form itself—this address changes depending on which state your business is located in. Do not mail it to the general IRS address. Include a copy of your EIN documentation (such as your EIN assignment letter) if this is your first address change with the IRS, though it is not always required. Send the form via regular mail or certified mail if you want proof of delivery. The IRS will send a confirmation letter to your new address once the change is processed.

Using your IRS online account to update your address

If you already have an IRS online account through Business Services Online or the IRS e-services portal, you can update your address without filing a form. Log in to your account, navigate to the profile or account settings section, and select the option to update your address. The change takes effect when ready in the IRS system, though it may take a few days to appear in all IRS databases.

To set up an IRS online account if you do not have one, visit IRS.gov and look for the Business Services Online registration page. You will need your EIN, business name, and the address currently on file with the IRS. Registration takes about 15 minutes and requires you to verify your identity. Once your account is active, you can update your address anytime without waiting for mail processing.

Updating your address with your state tax agency

The IRS and your state tax agency maintain separate records, so changing your address with the IRS does not automatically update it with your state. Contact your state's Department of Revenue or equivalent agency to file a separate address change. Most states allow you to file online through their tax portal, by mail, or by phone.

Some states require you to file a specific form (often called a "Change of Address" or "Notice of Change" form), while others let you submit a letter with your business name, EIN or state tax ID, old address, and new address. Check your state's website or call the business tax line to find out what they need. Processing time varies by state but typically ranges from one to three weeks.

What to do if you have an address change pending

If you have filed a return or owe taxes and your address is about to change, file Form 8822-B at least two weeks before you move. This gives the IRS time to process the change before correspondence arrives at your old address. If you move before the change is processed, the IRS may send notices to your old address, and your landlord or the new occupant may discard them.

If you have already moved and missed correspondence, contact the IRS at 1-800-829-1040 to confirm your new address over the phone. Have your EIN and business name ready. The IRS can flag your account to forward future mail to your new address, though this is temporary and you should still file Form 8822-B to make the change permanent.

Common mistakes to avoid when changing your address

The most common error is mailing Form 8822-B to the wrong IRS address. The form itself lists the correct mailing address for your state—use that address, not the general IRS address. Another mistake is forgetting to include your EIN or using an incomplete or incorrect EIN, which can delay processing by several weeks.

Do not assume the IRS will update your address automatically when you file your next tax return. Always file Form 8822-B or use your online account to make the change official. Also, remember that changing your address with the IRS does not change it with your state, your business bank, your business insurance company, or your vendors—you will need to contact each of them separately.

Timeline for address changes to take effect

If you file Form 8822-B by mail, expect the IRS to process it within 30 days of receipt. Add one to two weeks for mail delivery to the IRS, so the total time from mailing to confirmation is typically four to six weeks. If you update your address through your online IRS account, the change is when ready in the system, though it may take a few days to sync across all IRS databases and systems.

During the processing period, the IRS may still send correspondence to your old address. If you need to speed up the process, use your online account instead of mailing the form. If you do not have an online account and need the change urgently, call the IRS at 1-800-829-1040 to report the change verbally, then follow up by mailing Form 8822-B to create a permanent record.

Frequently Asked Questions

Do I need to file Form 8822-B if I am a sole proprietor?

You can file Form 8822-B, but you may also report the address change on your next tax return (Form 1040 or Schedule C). Form 8822-B is faster if you need the change processed before your next return is due. If you have an IRS online account, updating your address there is the quickest option.

What if my business moved but I am still using the old address for mail?

You should still file Form 8822-B with your actual business location. The IRS uses your address to route correspondence and notices. If you want mail sent to a different address (such as your accountant's office), you can request that separately by calling 1-800-829-1040.

How long does it take the IRS to confirm my address change?

The IRS typically processes Form 8822-B within 30 days of receipt, but mail delivery adds one to two weeks on each end. If you file through your online account, the change is when ready. You will receive a confirmation letter at your new address once the change is processed.

Can I change my address over the phone with the IRS?

You can report your address change verbally by calling 1-800-829-1040, and the IRS will update your account. However, this change is temporary. You should still file Form 8822-B or update your address through your online account to make the change permanent in the system.

Do I need to update my address with the state if I already updated it with the IRS?

Yes. The IRS and state tax agencies maintain separate records. You must contact your state's Department of Revenue or tax agency separately to update your business address with them. Check your state's website for the specific form or process they require.
