Short answer
IRS Form 8822-B is the one-page form a business files to tell the IRS about a changed business mailing address, business location, or responsible party. It is free, filed on paper rather than online, and usually takes about four to six weeks to process.
Key takeaways
- Form 8822-B is the IRS form a business uses to report a new mailing address, business location, or responsible party, and it is free and one page.
- As of 2026 there is no online option for Form 8822-B, so it is completed on paper and mailed to the IRS service center for your state.
- A change of business address or responsible party does not require a new EIN, and processing usually takes about four to six weeks.
Before you start
- Have your EIN and both the old and the new business address ready before you fill out the form.
- If the responsible party is changing, have that person's SSN, ITIN, or EIN, since the IRS asks for it within a set window.
Who this is for
- Business owners who moved and need to update the address on their EIN.
- Anyone changing the responsible party on file with the IRS.
- Owners lining up their IRS address with their state and bank records.
Form 8822-B is the form the IRS uses to keep a business's address and responsible party current, and it tends to come up right after a move or an ownership change. It is short and free, but a few details about who files it and how trip people up.
This guide covers what Form 8822-B is for, who has to file it and by when, how to fill it out, where to mail it, and the common questions about EINs and processing time.
What Form 8822-B Is For
Form 8822-B is a one-page form that notifies the IRS when certain business details change. It covers more than just a mailing address, which is part of why it has its own form separate from the individual change-of-address form.
- A change to the business mailing address the IRS has on file.
- A change to the business location, if it differs from the mailing address.
- A change to the responsible party, the person the IRS treats as controlling the entity.
Who Has to File It, and By When
Any business with an EIN (Employer Identification Number) can use Form 8822-B to update its address. The timing is where the two situations differ, so it helps to know which one applies to you.
- For a change of responsible party, the IRS instructions ask you to report it within 60 days of the change.
- For a change of address only, there is no fixed statutory deadline, but filing promptly keeps IRS mail reaching you.
- If you have not yet been assigned an EIN, you would handle the address as part of that application instead.

Form 8822-B vs Form 8822
The two forms look similar and get mixed up often. Form 8822 is for an individual or a household changing a personal address, while Form 8822-B is the business version that also handles the business location and responsible party.
If you are updating where the IRS sends your company's mail, Form 8822-B is the one. Using the individual form for a business change is a common reason an update does not land where you expect.
How to Fill It Out, Box by Box
The form is short, and most of it is straightforward once you have your details ready. Because the IRS updates form layouts over time, confirm the current line labels on the form itself as you go.
- Check the boxes for what is changing, such as the business mailing address or the responsible party.
- Enter your business name and EIN exactly as the IRS has them.
- Provide the old address and the new address, including any suite number.
- If the responsible party is changing, enter the new party's name and their SSN, ITIN, or EIN.
- Sign and date the form, since an unsigned form is a common reason one is sent back.
Where to Mail It, and Why There Is No Online Option
A lot of searches ask how to file Form 8822-B online, and the honest answer is that, as of 2026, the IRS does not offer an online filing option for it. The form is mailed on paper to the IRS service center for your state.
Because that service center depends on your state and is updated from time to time, the current mailing address is on the IRS instructions for Form 8822-B. It is worth confirming it there rather than reusing an address from an older guide.
Does Changing Your Address Need a New EIN?
No. Changing your business address or your responsible party does not require a new EIN. The EIN stays with the business, and Form 8822-B simply updates the details the IRS keeps alongside it.
A new EIN generally comes up only with a change in entity structure or ownership type, not a move. If you are relocating across state lines, our guide on moving an LLC to another state covers the wider picture.
Processing Time and Confirmation
The Form 8822-B instructions say it generally takes about four to six weeks to process an address or responsible party change. For an address change, the IRS typically mails confirmation notices — CP148A to your new address and CP148B to your old one — so if the details shown are correct, there is nothing more to do. Those notices, and every notice after them, only reach you if the address you filed is one you actually receive mail at.
That makes the reliability of the new address matter. If mail to it is missed, you may not notice the change did not take, which is why the address you put on the form is worth getting right before you file.
Get the New Address Right Before You File
Since the whole point of Form 8822-B is to route IRS mail to the right place, it helps to confirm the new address is a real, deliverable street address before you submit it. You can check how an address is classified and whether it is deliverable with our free Address Checker.
If you are still setting up the new address, you can establish a real US business address in one of several cities through save office onboarding, usually within about a day, and then keep it consistent across your IRS, state, and bank records. The full multi-channel update is covered in our guide on changing an LLC business address.
Form 8822-B is the short, free form that keeps your business address and responsible party current with the IRS: report a responsible-party change within 60 days, file the address change promptly, and mail the paper form to the service center for your state, since there is no online option.
Confirm the new address is deliverable before you file, keep it consistent across your IRS, state, and bank records, and a business move stops being something that quietly loses your IRS mail.
