How to Update Your Address with the IRS (Form 8822 Walkthrough)

USPS will forward your mail for twelve months, but it does not tell the IRS you moved. The IRS keeps writing to whatever address is on your last return - and the IRS doesn't email or call. Everything important comes through the mail.

If a notice, refund check, or deficiency letter goes to your old address and you never see it, the IRS treats you as if you received it. Penalties keep accruing. Deadlines pass. That's the real reason to update your address before tax season rolls around, not just because it feels tidy.

Download Form 8822 from irs.gov/form8822. It's one page (plus an instructions page) and free. At the top, Part I is labeled 'Complete This Part To Change Your Home Mailing Address'.

Almost everyone checks box 1 - that covers individual income tax returns (Forms 1040, 1040-SR, 1040-NR). Check box 2 only if your move also affects gift tax, estate tax, or generation-skipping transfer tax returns (Forms 706, 709, and the like). If you filed a joint return last year and you're now setting up a separate residence from your spouse, check the small box on the right side of line 1 too - that tells the IRS your address is changing but your spouse's may not be.

Line 3a is your name (first, middle initial, last). Line 3b is your Social Security number. If you file jointly, line 4a is your spouse's name and 4b is their SSN.

Lines 5a and 5b are for any prior names you've had - most commonly a maiden name after a marriage or a name change after a divorce. If you changed your name, make sure the Social Security Administration knows too (Form SS-5), or the IRS may have trouble matching your return to your earnings record.

Line 6a is your old home mailing address - the one that was on your last tax return. Write it the way it appeared on that return, even if there were minor formatting differences from what you'd write today.

Use line 6b only if your spouse's old address was different from yours (for instance, if you got married mid-year and filed jointly using two different addresses). For foreign filers, the form has dedicated rows for foreign country, province or county, and postal code below each address.

Line 7 is the new address - the one you actually want the IRS to start using. Include the street number, street name, apartment or suite number if any, city or town, state, and ZIP code.

If you use a P.O. box, the rule is narrower: use the box number only if your post office does not deliver mail to your street address. If your street address gets mail and you just prefer the P.O. box, use the street address here so refund checks and IRS notices don't get lost between two destinations.

Below the address section, Part II Signature is the legal part. The daytime telephone number at the top of Part II is optional - it gives an IRS agent someone to call if there's a question, which can shave weeks off a stuck form.

Sign on the line marked 'Your signature' and date it. For joint filers with a still-shared address, both spouses sign. If a power-of-attorney representative is signing on your behalf, they sign in the right-hand column and you'll need to attach a copy of Form 2848 (Power of Attorney) - the IRS won't process an address change from an unauthorized third party.

Page 2 of the form has a Where To File table. The IRS service center you mail to depends on the state in your old address - the one you're changing from. There are about a dozen possible addresses.

One shortcut: if you checked box 2 (gift/estate/GST tax), the form always goes to the same address - Department of the Treasury, Internal Revenue Service, Kansas City, MO 64999-0023 - regardless of the state you used to live in. For everyone else, find your old state in the IF/THEN table and use the matching address. Drop it in the mail. There's no fee.

Form 8822 covers your personal address. If you also run a business - even as a sole proprietor filing a Schedule C or business return - the business address change goes on a separate form, Form 8822-B, Change of Address or Responsible Party - Business. File one of each if both addresses are changing.

Same rule for kids. If a dependent child files their own return, they need their own Form 8822 for their personal address - it isn't covered by yours. After you mail the form, give it 4 to 6 weeks to process. The IRS does not send a confirmation. The clearest signal it worked is that your next IRS notice or refund check arrives at the new address.
