Does Form 8822 have a filing deadline?

No. The IRS sets no due date for Form 8822 and describes its use as voluntary, other than the separate 60-day rule for reporting a change of responsible party on Form 8822-B. The practical deadline is self-imposed: file it before you order transcripts or submit a catch-up package, and allow the four to six weeks the IRS says it generally takes to process a change of address.

Can I change my IRS address by phone from the UK?

Yes in principle. Revenue Procedure 2010-16 recognises clear and concise oral notification made in person or directly by telephone to an IRS employee with access to the Service Master File, who must verify your identity and will confirm the new address will be used for all purposes. From the UK the call cost, time difference and lack of a paper trail make it a poor first choice. Form 8822 gives you a dated posting record.

Will filing a late return update my address automatically?

It will, once the return is properly processed. Revenue Procedure 2010-16 defines that as a 45-day period beginning the day after receipt, with a filing-season exception treating a Form 1040 series return received in processible form after 14 February and before 1 June as processed on 16 July. That is far too slow to rely on if you need transcripts first, which is why the address change should come before the filing, not with it.

Do I need Form 8822-B for my UK limited company?

Only if the entity has a US EIN and an IRS record to correct, which is common where a UK company has US filing obligations or a US owner. Form 8822-B updates a business mailing address, business location or responsible party, and the IRS requires responsible party changes to be reported within 60 days. It goes to Ogden, Utah for any old business address outside the United States, not to Austin.

Does telling HMRC my new address tell the IRS as well?

No. HMRC and the IRS maintain separate records and do not pass routine address changes between them. You tell HMRC through its online change of address service or the HMRC app at gov.uk, or by filing a Self Assessment return showing the new details, and you tell the IRS separately on Form 8822. Filing one does nothing for the other, and a change of country requires both.

Is an IRS notice valid if it went to an old US address I never see?

Generally yes. Revenue Procedure 2010-16 states that when a notice or document is sent to a taxpayer's last known address it is legally effective even if the taxpayer never receives it. The last known address is the address on your most recently filed and properly processed return unless you gave clear and concise notification of a different one. Non-receipt does not stop penalties and interest accruing.

Form 8822: Change Your IRS Address From the UK

If you are a US person living in the UK with missed US tax returns, the single most consequential piece of data the IRS holds about you is not an income figure, it is your address. Form 8822, Change of Address, is the IRS form an individual uses to tell the Service that a home mailing address has changed, and it is filed on its own, by post, and never attached to a return. The IRS confirms the purpose and the current revision at https://www.irs.gov/forms-pubs/about-form-8822, and the form itself, currently the February 2021 revision, is at https://www.irs.gov/pub/irs-pdf/f8822.pdf. Businesses use the parallel Form 8822-B at https://www.irs.gov/forms-pubs/about-form-8822-b. The IRS states that it generally takes four to six weeks to process a change of address. For a UK-resident taxpayer with unfiled years, that four to six weeks is not administrative noise. It is the difference between a catch-up project you control and a notice cycle that runs to conclusion in a letterbox you no longer own.

Why the address on file decides the outcome of missed US tax returns

In the returns we prepare for clients in London, Edinburgh and the Home Counties, the address problem is almost never the presenting issue. The client comes to us about six unfiled Forms 1040, a stack of unreported UK bank and platform accounts, or a UK company that needs Form 5471 disclosure. The address is discovered later, usually when transcripts arrive nowhere. By then the IRS has often been writing for years to a Manhattan apartment, a parents' house in New Jersey, or a former marital home in California.

The reason this matters is a doctrine, not a courtesy. Large parts of the Internal Revenue Code require the IRS to send a document to a taxpayer's last known address, and once it has done so the document is effective whether or not the taxpayer ever reads it. Revenue Procedure 2010-16, published at https://www.irs.gov/pub/irs-wi/rp-10-16.pdf, states the point without hedging: when a notice or document is sent to a taxpayer's last known address, it is legally effective even if the taxpayer never receives it. The same revenue procedure defines the last known address, by reference to Treasury Regulations section 301.6212-2(a), as the address on the taxpayer's most recently filed and properly processed return, unless the Service has been given clear and concise notification of a different address.

Read those two sentences together and the exposure becomes obvious. A person who left the United States in, say, 2018 and has filed nothing since has a last known address frozen at whatever appeared on the final return they filed as a US resident. Every statutory notice in the list at section 3.01 of Rev. Proc. 2010-16 can validly be posted there: the notice of deficiency under section 6212(b), the notice and demand for tax under section 6303(a), the notice of intention to levy under section 6331(d)(2)(C), the notice and opportunity for hearing on a lien filing under section 6320(a)(2)(C). The clock on each runs from the date of mailing, not the date of reading.

The Taxpayer Advocate Service explains the sharpest example at https://www.taxpayeradvocate.irs.gov/notices/90-day-notice-of-deficiency/. A notice of deficiency gives 90 days to petition the United States Tax Court, extended to 150 days where the notice is addressed to a person outside the United States, and that period is prescribed by law and cannot be extended by the IRS. Note the trigger for the longer period. It attaches to a notice addressed abroad. A UK-resident taxpayer whose IRS record still shows a US street address is not obviously in that category, and it is not a point you want to be arguing about after the fact. Let the period lapse and the deficiency can be assessed without the taxpayer ever having had the chance to contest it without first paying.

What is Form 8822 and who signs it?

Form 8822 is a one-page notification that the IRS treats as clear and concise written notice of a change of home mailing address. Section 5.04 of Rev. Proc. 2010-16 names it expressly as a form that can be used for that purpose. The form instructions set out the mechanics, and several of them catch cross-border filers out.

It is not attached to a return. The form says so on its face, and it is posted separately to a service centre address that depends on your old address, not your new one.
Part I line 1 is the box an individual income tax filer checks, covering Forms 1040, 1040-SR and 1040-NR. Line 2 relates to other categories of return that are outside the scope of this article.
If your last return was a joint return and you are now establishing a residence separate from that spouse, there is a box on line 1 to say so. Check it and your spouse does not need to sign.
If your last return was a joint return and you are not separating residences, your spouse must also sign. Rev. Proc. 2010-16 adds that joint filers should provide both names, both taxpayer identification numbers and both signatures.
Lines 5a and 5b capture prior names after a marriage or divorce. The instructions also tell you to notify the Social Security Administration so its record matches the name on your return.
A representative can sign, but a copy of the power of attorney must be attached, and Form 2848 is the vehicle the instructions point to. The IRS states plainly that it will not complete an address change from an unauthorized third party.

One instruction on the form deserves quoting almost in full because it is the whole argument for filing it. The Privacy Act notice says that use of the form is voluntary, but that if you fail to provide the IRS with your current mailing address you may not receive a notice of deficiency or a notice and demand for tax, and that despite the failure to receive such notices, penalties and interest will continue to accrue on the tax deficiencies. The IRS is telling you, on the form, that non-receipt buys you nothing.

How do you enter a UK address on Form 8822?

The foreign address instruction on Form 8822 is short and easy to get wrong. Follow the country's practice for entering the postal code, and do not abbreviate the country name. In practice that means the UK postcode goes in the foreign postal code box in its normal UK format, the county or province box takes the county where you use one, and the country is written out as United Kingdom, not UK or GB. The main address line takes the flat or house number, street, and town or city. Lines 6a, 6b and 7 each have their own foreign country, foreign province or county and foreign postal code fields, so both an old foreign address and a new foreign address can be entered properly.

Two further instructions matter for UK-resident clients. A PO box should be entered instead of a street address only where the post office does not deliver to the street address, which is rarely the case in the UK. And if you receive US correspondence in care of a third party such as an accountant, the instructions tell you to enter C slash O followed by that party's name and address. Where a client is genuinely peripatetic, a stable care-of address with a professional adviser is often the more robust answer than a residential address that will change again in eighteen months.

Where do you send Form 8822 from the UK?

This is the part almost everyone gets wrong on the first attempt, because the Where To File table on page 2 of Form 8822 keys off your old home mailing address, not the UK address you are moving to. The table works as follows.

Old address in Alabama, Arkansas, Delaware, Georgia, Illinois, Indiana, Iowa, Kentucky, Maine, Massachusetts, Minnesota, Missouri, New Hampshire, New Jersey, New York, North Carolina, Oklahoma, South Carolina, Tennessee, Vermont, Virginia or Wisconsin: Department of the Treasury, Internal Revenue Service, Kansas City, MO 64999-0023.
Old address in Florida, Louisiana, Mississippi or Texas: Department of the Treasury, Internal Revenue Service, Austin, TX 73301-0023.
Old address in Alaska, Arizona, California, Colorado, Connecticut, District of Columbia, Hawaii, Idaho, Kansas, Maryland, Michigan, Montana, Nebraska, Nevada, New Mexico, North Dakota, Ohio, Oregon, Pennsylvania, Rhode Island, South Dakota, Utah, Washington, West Virginia or Wyoming: Department of the Treasury, Internal Revenue Service, Ogden, UT 84201-0023.
Old address in a foreign country, or an APO or FPO address, or where you file Form 2555 or Form 4563, or are a dual-status alien: Department of the Treasury, Internal Revenue Service, Austin, TX 73301-0023.

The rows can overlap, and that overlap is where the practical judgement sits. A client whose old home address was in New York falls in the Kansas City row on a literal reading, but if the same client claims the foreign earned income exclusion on Form 2555 they also fall in the final row, which routes to Austin. In the returns we prepare, the Austin routing is the one we use for a UK-resident client who is filing Form 2555, because it is consistent with where a Form 1040 bearing a foreign address is filed in the first place. The IRS filing address chart at https://www.irs.gov/filing/where-to-file-addresses-for-taxpayers-and-tax-professionals-filing-form-1040 directs taxpayers in a foreign country to Department of the Treasury, Internal Revenue Service, Austin, TX 73301-0215, USA, with payments enclosed going instead to Internal Revenue Service, P.O. Box 1303, Charlotte, NC 28201-1303, USA. Sending the address change to the campus that already handles your file is the lower-friction choice.

When does a UK business owner need Form 8822-B instead?

Form 8822 changes a home mailing address. It does not touch an entity record. Form 8822-B, currently the December 2019 revision at https://www.irs.gov/pub/irs-pdf/f8822b.pdf, is used to notify the IRS of a change to a business mailing address, a business location, or the identity of the responsible party. The IRS notes at https://www.irs.gov/forms-pubs/about-form-8822-b that it is for entities with an EIN application on file, and that changes in responsible party must be reported within 60 days. The form instructions tie that requirement to Regulations section 301.6109-1(d)(2)(ii), and the Privacy Act notice makes the distinction that matters: where an entity with an EIN has had a change of responsible party, use of the form is mandatory, whereas otherwise it is voluntary.

The filing addresses differ from Form 8822, which is a common trap where a client is filing both at once. Form 8822-B routes old business addresses in a first group of states to Internal Revenue Service, Kansas City, MO 64999, and the remaining states plus, in the words of the form, any place outside the United States, to Internal Revenue Service, Ogden, UT 84201-0023. So a UK-incorporated company or a US LLC managed from London sends Form 8822-B to Ogden while its owner sends Form 8822 to Austin. Two forms, two envelopes, two campuses. The form also states expressly that if you are changing both home and business addresses you need both forms.

What are the alternatives to filing Form 8822?

Form 8822 is one of several routes. IRS Tax Topic 157 at https://www.irs.gov/taxtopics/tc157 and the address change FAQ at https://www.irs.gov/faqs/irs-procedures/address-changes/address-changes set out the others, and Rev. Proc. 2010-16 supplies the technical conditions and the timing for each.

On a return. Filing a return showing the new address updates the address of record once the return is properly processed. Rev. Proc. 2010-16 defines properly processed as after a 45-day processing period beginning the day after receipt, with a filing-season exception: a Form 1040 series return received in processible form after 14 February and before 1 June is treated as properly processed on 16 July.
Written notification. A signed letter stating specifically that you want the address of record changed, giving your full name, old address, new address and taxpayer identification number, sent to the campus serving your old address. Rev. Proc. 2010-16 warns that a new address in the letterhead of correspondence will not by itself change the address of record. It also confirms that IRS correspondence returned with corrections marked on the address counts as clear and concise written notification.
Electronic notification. New address information submitted through a secure application on irs.gov that requires you to verify your identity. The revenue procedure is explicit that ordinary email to an IRS address does not qualify.
Oral notification. A statement made by the taxpayer, in person or directly by telephone, to an IRS employee with access to the Service Master File, who must verify identity and will confirm that the new address will be used for all purposes.
Postal service data. The IRS will automatically update the address of record from a new address held in the United States Postal Service National Change of Address database, under Treasury Regulations section 301.6212-2(b)(2). Rev. Proc. 2010-16 nevertheless advises taxpayers to notify the Service directly to ensure a timely and accurate update.

For a move to the UK we treat the postal route as no route at all. A US-to-UK relocation is not the ordinary domestic forwarding case those systems were built for, and Rev. Proc. 2010-16 itself carries the caution. Two exclusions in the revenue procedure are worth committing to memory as well. The term return, for address purposes, does not include an application for extension of time to file or a power of attorney. A new address on Form 4868 or on Form 2848 will not update the address of record. Practitioners lose clients' notices on that point every year.

The transcript trap: your IRS history posted to a house you left

Every serious catch-up project starts with transcripts. You want the account transcript to see what has been assessed, the wage and income transcript to see what third parties reported, and the verification of non-filing letter to establish which years are genuinely open. The IRS sets out the types and coverage at https://www.irs.gov/individuals/transcript-types-and-ways-to-order-them: the tax return transcript covers the current and three prior tax years, the account transcript covers the current and nine prior years online but only the current and three prior years by post or phone, the wage and income transcript covers the current and nine prior years and is capped at approximately 85 income documents, and a verification of non-filing letter for the current year is only available after 15 June.

Here is the mechanism that quietly wrecks UK catch-up projects. Transcripts ordered by post are sent to the address the IRS already holds. The IRS page at https://www.irs.gov/individuals/get-transcript states that a mailed transcript goes to the address on file, arriving in five to ten calendar days. Form 4506-T, currently the April 2025 revision at https://www.irs.gov/pub/irs-pdf/f4506t.pdf, carries a note in the body of the form: effective July 2019 the IRS will mail tax transcript requests only to your address of record, having stopped all third-party mailings of requested transcripts. So a UK filer who requests transcripts by post while the record still shows a US address has just posted their own tax history to that US address.

The IRS says the quiet part out loud in two places. The Form 4506-T instructions to line 4 note that if the addresses on lines 3 and 4 are different and you have not changed your address with the IRS, you should file Form 8822, or Form 8822-B for a business address. The transcript FAQ at https://www.irs.gov/individuals/transcript-services-for-individuals-faqs is blunter still: do not use your old address, because the transcript will not get forwarded to you, and you need to file Form 8822 before you submit Form 4506-T. Remember too that Form 4506-T must be received by the IRS within 120 days of the signature date, so a request signed while you wait out a four to six week address update can expire in the queue if you are careless about dates.

Sequencing: update the address before you order transcripts or file

Almost every published guide treats the address change as an afterthought, something you tidy up once the returns are done. That is backwards. The address change is the first task in the project, because two of the three things you do next depend on it. Here is the order we work in.

File Form 8822 first, and Form 8822-B at the same time if there is an entity, allowing for the four to six weeks the IRS states it generally takes to process a change of address.
While that runs, establish access to the IRS individual online account so that transcripts and notices can be viewed rather than posted, and reconstruct UK-side records: bank and platform statements, employer share plan documents, HMRC filings.
Order transcripts only once the address has updated, or take them online. Order the wage and income transcripts for the earliest years first, since they are the ones most likely to time out of availability.
Then build the returns. For a Streamlined Foreign Offshore submission, the requirements at https://www.irs.gov/individuals/international-taxpayers/u-s-taxpayers-residing-outside-the-united-states are three years of delinquent or amended Forms 1040 or 1040-X, six years of FBARs filed electronically through the FinCEN BSA E-Filing System, and a signed Form 14653 certifying non-willfulness and the non-residency test of no US abode and at least 330 full days outside the United States in one of the relevant years.
Post the streamlined package to Internal Revenue Service, 3651 South I-H 35, Stop 6063 AUSC, Attn: Streamlined Foreign Offshore, Austin, TX 78741, with the correct current UK address on every return in the package.

Doing it in this order also fixes the address twice. The address change updates the record now, and the returns you file carry the same address forward, so the address of record is consistent whichever route the IRS uses to derive it. The eligibility conditions and the general framework for the streamlined route are at https://www.irs.gov/individuals/international-taxpayers/streamlined-filing-compliance-procedures, which also confirms that streamlined returns are processed like any other return.

A worked scenario

The following is an illustration and not a client matter. Assume an investment banker, a US citizen, who moved from New York to London in 2019 and last filed a Form 1040 for 2018 showing a Manhattan address. She has not filed since. Her UK employment income is substantial, she holds a UK current account, a stocks and shares account on a UK platform, and vested shares under an employer plan, with aggregate balances comfortably over the FBAR reporting threshold of 10,000 US dollars at some point in each year. Any dollar figures used here are illustrative only.

Her last known address is the Manhattan apartment, which she sublet and then gave up. Under the IRS FBAR guidance at https://www.irs.gov/businesses/small-businesses-self-employed/report-of-foreign-bank-and-financial-accounts-fbar she has six unfiled FinCEN Forms 114 as well as the unfiled income tax returns. When she engages us, the first thing we ask for is not her P60s, it is confirmation of what address the IRS holds. She does not know. Nobody does, which is itself the finding.

If in the meantime the IRS had issued a CP59, the notice described at https://www.irs.gov/individuals/understanding-your-cp59-notice as telling a taxpayer the IRS has no record of a prior year return, it went to Manhattan. If the matter had escalated to a notice of deficiency, that too went to Manhattan, and it was legally effective on posting. The response window would have run and closed while she was in Canary Wharf, unaware. At that point the manageable problem, three years of returns and six FBARs under a streamlined submission, has become an assessed liability she must first pay in order to contest. Nothing about her facts changed. Only the address did, and only because she never told the IRS.

Handled the other way round, the sequence is unremarkable. Form 8822 goes to Austin with United Kingdom written out in full and the postcode in UK format. Four to six weeks later transcripts are ordered and arrive in London. The wage and income transcripts confirm what the IRS actually holds for her, the account transcripts confirm no substitute assessments have been made, and a streamlined package is prepared on facts rather than on guesses.

What Form 8822 does not do

It does not update FinCEN. The FBAR is filed with FinCEN through the BSA E-Filing System, not with your income tax return, and it carries its own filer address fields on FinCEN Form 114. Form 8822 has no effect there.
It does not update HMRC. The two authorities do not share address changes. HMRC is told separately through the online service or the HMRC app described at https://www.gov.uk/tell-hmrc-change-of-details/change-of-address, or through a Self Assessment return.
It does not update the Social Security Administration, which is why the Form 8822 instructions tell you separately to notify the SSA of a name change.
It does not update your address on a power of attorney or an extension application, and neither of those updates the IRS address of record either.
It does not oblige the IRS to keep writing to an address indefinitely. Rev. Proc. 2010-16 provides that, other than for notices required by law to go to the last known address, the Service is not required to continue sending notices to an address once a delivery attempt shows the taxpayer cannot be contacted there.

The failure modes we see most often

Using a US relative's address as a convenience. It works until the relative moves, dies or stops opening the post, and it puts a US address on your record while you argue elsewhere that you are resident abroad.
Abbreviating the country. The instruction is not to abbreviate the country name. UK, GB and Great Britain are all avoidable friction on a form that is keyed by hand.
Sending Form 8822 to the campus serving the new address. The table is keyed to the old address and the special categories, not the destination.
Filing only Form 8822 when there is also a US LLC or a corporation with an EIN, leaving the entity record pointing at a defunct US address while the individual record is current.
Ordering transcripts first and the address change second, then waiting for post that has already been delivered three thousand miles away.
Assuming a spouse's signature is not needed. If the last return filed was joint and you are not establishing a separate residence, the instructions require both signatures.

None of this is difficult. It is a one-page form and a stamp. What makes it worth writing about is the asymmetry: the cost of filing it is trivial and the cost of not filing it is an assessment you never had the chance to contest. For a UK-resident US person with unfiled years, updating the address is not the last item on the checklist. It is the first.
