The fix was simple, file a short form that tells the IRS exactly where to reach you. If you have moved, you need to update your “last known address” with the IRS so notices, refunds, and deadlines get to you on time. That form is IRS Form 8822.
Short form, big consequences. If the IRS sends a notice to your last known address, it counts as delivered even if you never see it. Filing Form 8822 prevents that risk.
Key takeaways
- Form 8822 updates your IRS “last known address” for individual tax matters. It is the standard way to change your home mailing address with the IRS.
- Processing usually takes about 4 to 6 weeks from IRS receipt. Plan your timing so time sensitive letters do not go to your old address.
- You must mail it. The form is a paper submission to the address in the instructions. There is no e file option for Form 8822.
- Joint filers can use one form, but both should be identified and sign, or attach a power of attorney if a representative signs.
- Businesses use Form 8822 B, not Form 8822. If the responsible party changes, businesses must report within 60 days.
- Alternatives exist, like updating your address on your next return, a signed letter, or calling the IRS after identity verification, but do not rely only on USPS forwarding.
What Form 8822 does and why it matters
Form 8822 is how you tell the IRS that your home mailing address has changed for individual returns, and for related areas like gift or estate filings that use your personal taxpayer account. When you file it, the IRS updates your “last known address,” which is the address it uses for notices, refunds, and statutory deadlines.
Here is the part many people miss. The IRS treats mail sent to your last known address as delivered. If you moved but did not update that address, the clock on a notice or an audit letter can still run. That is why a simple address update protects your response rights and your refunds.
What about USPS forwarding, or changing your address with the post office? USPS changes can sometimes flow through the postal database to the IRS, however not all post offices forward government checks, and relying on forwarding alone can still lead to missed or delayed IRS mail. The IRS itself says you should notify them directly.
If you are handling a business address change, use Form 8822 B instead. It covers business mailing address and business location, and it is also how you report a change in the entity’s responsible party within 60 days.
Who should file and when
You should file Form 8822 any time your individual mailing address changes and you want the IRS to reach you at the new address. That includes married couples filing jointly, recent graduates with new apartments, retirees who moved states, and anyone who moved and expects time sensitive mail from the IRS. You can also choose to put the new address on your next filed tax return, or send a signed letter with your identifying details, but the IRS standard method is mailing Form 8822.
Timing matters. The IRS says it can take about four to six weeks to fully process an address change. If you think a notice or refund is coming soon, file the form right away rather than waiting for your next return.
Joint filers have options. If you still share the same home, you can use one Form 8822 for both of you, include both names, both SSNs or ITINs, and both signatures. If you now live at different addresses, each spouse should file a separate change so the IRS has the correct address for each person.
Advisors and representatives can file on your behalf only with proper authority. If someone else signs for you, attach Form 2848 or another valid power of attorney that matches IRS records.
What this covers, and what it does not
- Form 8822 covers individual home mailing address changes. It does not update an employer’s or other entity’s address. For those, use 8822 B.
- If the change relates to employment tax filings, the IRS sends CP 148A to the new address and CP 148B to the old one to confirm the change. That confirmation helps you spot any incorrect updates.
- Expect no formal confirmation for an individual Form 8822. Give it the full processing window before assuming it is in place. The IRS’s general guidance is that address changes can take about four to six weeks to complete after receipt.
A quick story from the field
In our work with taxpayers and the firms that serve them, we often see year end moves create a perfect storm, new address, refund in flight, and a CP letter that lands at the old place. The fastest recoveries always start with a clean 8822 on file and proof of mailing saved with the tax documents. That one habit keeps the entire season calmer.

What you need before you start Form 8822
Gather the details the IRS uses to match your account so your update moves fast.
- Your legal name as it appears on your last return, plus any prior name.
- Your SSN or ITIN.
- Your old mailing address, exact to the unit number, the way it appeared on your last return.
- Your new mailing address in USPS format, or foreign format if you moved abroad.
- For a joint filing couple, your spouse’s name and SSN or ITIN.
- Signatures for everyone whose address is being updated, or a power of attorney if a representative signs.
If you are moving outside the United States, write the address as used locally, include province or state and postal code, and spell the country in English. If your post office does not deliver to your street, a PO box is acceptable. For mail sent to a third party, use “c o” with that person’s name and address. These formatting points help the IRS route mail correctly.
Step by step, how to complete and mail Form 8822
- Fill in your identifying information Enter your full legal name and SSN or ITIN the same way they appear on your last filed return. If you filed jointly, enter both taxpayers and both numbers.
- Tell the IRS which accounts to update Check the boxes for the return types that apply, for most individuals this is the Form 1040 series. Gift or estate filers can also use 8822 for those account types.
- Enter the old address exactly as the IRS has it Copy it the same way you used it on the last return, include any apartment, suite, or unit number. This is how the IRS ties the new address to the right account.
- Enter the new mailing address Use standard USPS formatting for a U.S. address or the full foreign format. Add “c o” if a representative will receive mail for you.
- Sign and date Sign where indicated. For a joint filing couple, include both signatures. If a representative signs, attach Form 2848 or other valid authorization.
- Mail it to the IRS address in the instructions Print and mail the signed form to the IRS service center listed for your state. Do not attach it to a tax return. Keep a copy and proof of mailing with your records.
Tip, use a trackable mail option and save that receipt with your tax file. If a notice goes astray during the 4 to 6 week processing window, your receipt shows when you asked the IRS to update your address.
Joint filers, dependents, and special cases
Joint return, same address
If you still share one home, you can file one Form 8822 that lists both names, both SSNs or ITINs, and the new joint address. Signatures for both spouses are recommended so the IRS can update both accounts tied to that joint return.
Joint filers now at different addresses
When a married couple no longer shares a home, each person should file a separate address change so the IRS has the correct address for each taxpayer. This applies even if you still plan to file a joint return.
Dependents who file their own returns
If a dependent files a return under their own SSN or ITIN, submit a separate Form 8822 for that person when their mailing address changes. A parent or guardian can sign only with proper authority, attach the power of attorney if required.
Using nontraditional or foreign addresses
Use a PO box only if USPS does not deliver to your street address. For overseas moves, write the address in local format, include the postal code, and spell the country in English. APO and FPO addresses are valid when they are your regular mailing address.
Alternatives to filing Form 8822
If filing the form is not convenient, you still have ways to update the IRS, each with tradeoffs.
| Method | How it works | When it helps most |
| Next filed return | Put your new address on your next return and the IRS updates when it processes that return | Good when you are about to file and do not expect time sensitive mail before processing |
| Signed written statement | Mail a signed letter with your full name, SSN or ITIN, old and new addresses, and signature to the address where you filed your last return | Useful if you cannot print the form but want the update started now |
| By phone or in person | Tell the IRS after identity verification, have your SSN or ITIN and both addresses ready | Helpful if you need to confirm an update or cannot mail a form |
| Business changes | Use Form 8822 B for business address or responsible party updates | Required for entities and for responsible party changes within 60 days |
These options come from the IRS’s address change guidance and procedures. Even so, the IRS cautions that USPS forwarding is not enough by itself, since not all post offices forward government checks. Directly notifying the IRS is still best.
Processing timelines, proof of mailing, and what to expect
- The IRS says a change of address request can take about 4 to 6 weeks to fully process after receipt. Plan for that window, especially near filing season when paper volumes spike.
- You usually will not receive a confirmation letter for an individual change. Give it the full window, then check the next piece of IRS mail or call to confirm after identity verification.
- For employment tax related business address changes, the IRS issues CP 148A and CP 148B to confirm the update at both the new and old addresses.
Keep a copy of the signed form and a mailing receipt. If something time sensitive is misrouted during that window, your proof shows you acted quickly.
Common mistakes that slow things down
- Leaving off an apartment or unit number so the old address does not match IRS records.
- Forgetting the second signature on a joint filing update.
- Mailing to the wrong IRS service center for your state.
- Assuming USPS forwarding alone will cover refunds and notices. The IRS wants direct notice.
- Using Form 8822 for a business. Entities must use 8822 B, and responsible party changes have a 60 day rule.
