Moved Back from the UK? Streamlined Procedures After Moving Back to the US

Streamlined procedures after moving back to the US: an introduction

The streamlined procedures after moving back to the US still work, but your route depends on where you lived in the last three tax years. If one of those years was spent in the UK without a US home, the Foreign Offshore route may still be open. If not, you usually need the Domestic Offshore route, which carries a 5% penalty.

This article is for Americans who lived in Britain, have now returned, and know their past filings were incomplete. It explains how the streamlined procedures after moving back to the US differ from filing while abroad. Our full guide to IRS Streamlined Filing from the UK covers the procedures in depth.

Why streamlined procedures after moving back to the US need a fresh look

The Streamlined Filing Compliance Procedures are an IRS programme for taxpayers whose failures were not wilful. The IRS defines non-wilful conduct on its Streamlined Filing Compliance Procedures page as conduct due to negligence, inadvertence or mistake. A good-faith misunderstanding of the law also counts. However, your move home changes which version fits. The test looks backwards, so a year in London can still help you today.

Who this applies to

This applies to US citizens and green card holders who missed FBARs, left UK income off their returns, or never filed while abroad. For example, many people only learn about ISAs, UK pensions or FBARs after they return. Furthermore, US banks and employers ask fewer questions about UK accounts, so problems stay hidden for years.

Can you still use the Foreign Offshore route after moving back?

Yes, if you meet the non-residency test in at least one of the three most recent years. For streamlined procedures after moving back to the US, that year can be one you spent in the UK before your move.

The exact non-residency wording

The IRS page for US taxpayers residing outside the United States sets the test. You qualify if, in any one or more of the most recent three years for which the return due date has passed, you had no US abode. In that same year, you must also have been physically outside the United States for at least 330 full days. The due date includes a properly applied for extended due date. Therefore, your current address does not decide the matter.

What a US abode means

An abode is, broadly, the place where your economic, family and personal ties sit. The IRS page says temporary US visits do not necessarily put your abode in the US. Similarly, keeping a US house does not by itself mean your abode is there. The page points to IRS Publication 54 for the meaning of abode. In our experience, a full year living and working in the UK usually meets both parts, provided your US visits were short.

Joint returns need both spouses to qualify

For joint filers, the IRS page says both spouses must meet the non-residency requirement under the Foreign route. As a result, a couple where one spouse moved back early may not qualify jointly. In that case, the Domestic route may fit instead, or the two spouses may need separate thinking. We work this out before any return is prepared.

How does the three-year window move once you are home?

Under the streamlined procedures after moving back to the US, the window rolls forward each time a new return due date passes. Consequently, each year you spend at home pushes your UK years further out of reach.

Which years count today

Today is 19 October 2026. The 2025 return was due on 15 April 2026, or 15 October 2026 with an extension. So the three most recent years are now 2023, 2024 and 2025. If you lived in the UK for all of 2023, that year may carry you into the Foreign Offshore route. Additionally, the FBAR period covers the six most recent years, which today means 2020 to 2025.

When the window shifts next

The 2026 return is due on 15 April 2027. Once that date passes, the window becomes 2024, 2025 and 2026. Some practitioners argue that a properly extended 2026 return delays the shift to 15 October 2027. However, that reading is not settled. Therefore, we treat 15 April 2027 as the cautious date for anyone relying on 2023.

Why timing matters

A part year in the UK rarely gives 330 full days outside the US. For example, someone who left London in August 2024 spent about seven months abroad that year. So 2024 fails the day count. Once 2023 drops out of the window, that person usually loses the Foreign route for good. In short, the streamlined procedures after moving back to the US reward acting early.

When does the Domestic Offshore route apply instead?

The Domestic Offshore route applies when you fail the non-residency test in all three years. However, for streamlined procedures after moving back to the US, it is only open if you filed original returns for those years.

Original returns must already have been filed

The IRS page for US taxpayers residing in the United States sets two key conditions. First, you must fail the non-residency requirement. Second, you must have filed a US return, if one was required, for each of the three most recent years. The page also says you may not file delinquent income tax returns under these procedures. Consequently, the Domestic route fixes returns that were filed but wrong, not returns that were never filed.

The 5% miscellaneous offshore penalty

The miscellaneous offshore penalty is a one-off Title 26 penalty charged under the Domestic route. The IRS page sets it at 5% of the highest aggregate balance or value of your covered foreign financial assets. You add up the year-end balances for each year and take the highest total. By contrast, the Foreign route carries no such penalty. Accordingly, a qualifying UK year can be worth a great deal.

What counts towards the penalty base

The base includes assets that should have been on an FBAR or Form 8938 but were not. It also includes assets that were reported but whose income was left off a return. Examples include UK bank accounts, ISAs, foreign shares and UK funds. Moreover, the IRS says the penalty replaces accuracy-related, information return and FBAR penalties for eligible taxpayers. Our article on Streamlined Foreign versus Domestic Offshore compares the two in more detail.

What do you file under each route?

Both routes need three years of returns, six years of FBARs and a signed certification. The details of streamlined procedures after moving back to the US differ in ways that matter.

Returns and information returns

Under the Foreign route, you file delinquent or amended returns for the three years, with all required information returns. You use Form 1040 for a year never filed and Form 1040-X for a year already filed. Under the Domestic route, you file amended returns only. In both, you include forms such as Form 8938 where they were required. You also pay the tax and interest due, plus the 5% penalty under the Domestic route.

Six years of FBARs

The FBAR is FinCEN Form 114, the annual report of foreign financial accounts. Both routes need FBARs for the six most recent years whose FBAR due date has passed. You file them through FinCEN's BSA E-Filing System. The IRS tells you to choose "Other" as the late-filing reason and enter "Streamlined Filing Compliance Procedures". For UK accounts, our article on FBARs for Americans in the UK explains what to include.

Certification forms 14653 and 14654

Each route has its own certification. The Foreign route uses Form 14653, the certification by a US person residing outside the US. The Domestic route uses Form 14654, the certification by a US person residing in the US. In it, you certify that your failures resulted from non-wilful conduct. In our experience, a specific and honest account of what happened is far stronger than stock wording.

Paper returns, marked in red

Both IRS pages say the returns go on paper, and electronic submissions are not accepted. You write "Streamlined Foreign Offshore" or "Streamlined Domestic Offshore" in red at the top of each return. The FBARs are the exception, because they must be filed electronically. Notably, streamlined returns are not audited automatically, but they can still be selected for examination.

What about state returns and UK accounts you kept open?

Streamlined procedures after moving back to the US deal only with federal filings. Your state may want a return from the date you moved in. Meanwhile, UK accounts you kept open still need US reporting every year.

Part-year state returns

A part-year resident is someone who lived in a state for only part of the tax year. Most states with an income tax ask for a part-year return in the year you arrive. For instance, the California Franchise Tax Board says part-year residents pay tax on worldwide income while resident. Similarly, New York explains its rules in its nonresident and part-year resident FAQs. Importantly, the federal streamlined procedures after moving back to the US do not cover state returns. So amended federal returns may also mean amended state returns.

FBARs and Form 8938 for UK accounts

Your UK current account, savings and ISA still count after you leave. The FBAR applies when your foreign accounts together exceed $10,000 at any time in the year. However, Form 8938 thresholds fall once you live in the US. The IRS comparison of Form 8938 and FBAR requirements sets them at over $50,000 at year end or $75,000 at any time, for a single filer in the US. For joint filers in the US, the figures are $100,000 and $150,000. UK funds may also be PFICs, as our article on PFICs and UK funds explains.

The UK side: final return, split year and P85

Split year treatment is a UK rule that divides your year of departure into a UK part and an overseas part. HMRC's manual on split year treatment lists three cases for leaving. One is ceasing to have a home in the UK. If you file Self Assessment, GOV.UK's page on telling HMRC you are leaving says to complete the residence pages, form SA109. Otherwise, you use form P85, which is not needed if you send a Self Assessment return.

What if neither streamlined route fits?

If you never filed and have no qualifying UK year, the streamlined procedures after moving back to the US are closed to you. The same applies if your conduct was wilful. Other routes exist, but none is penalty-free.

No original returns and no qualifying year

This is the hardest gap. The Domestic route bars delinquent returns, and the Foreign route needs a non-residency year. As a result, you may need to file late returns in the normal way, with a reasonable cause statement where it helps. The IRS page of options for undisclosed foreign assets also lists the delinquent international information return procedures. However, the IRS says penalties may still be assessed under them. Practice here varies, so we take the cautious approach and assume penalty risk.

Wilful conduct and late FBARs

If your failure was wilful, the streamlined certification is not open to you. Instead, the IRS points to its Criminal Investigation Voluntary Disclosure Practice, where you should take legal advice. Separately, the IRS removed its Delinquent FBAR Submission Procedures page in July 2026. Therefore, a late FBAR filed on its own is not a penalty-free route. It may still be the right step, but it carries the risk of a penalty.

An example: Sarah returns to Boston

Consider a typical case, which is an illustration rather than a real client. Sarah is a US citizen who lived in London from 2018 until August 2024. She filed US returns every year using the foreign earned income exclusion. However, she never filed FBARs and left her cash ISA interest off each return. She moved to Boston, kept her UK accounts open and learned of the problem this autumn.

In 2023, Sarah lived in London all year and visited the US for two weeks. So she had no US abode and spent well over 330 full days abroad. Accordingly, 2023 meets the non-residency test, and the Foreign route is open today. She files amended returns for 2023 to 2025, FBARs for 2020 to 2025, and Form 14653. Crucially, she aims to submit before 15 April 2027, when 2023 drops out.

When the answer changes

Suppose Sarah waits until summer 2027. Then her window is 2024 to 2026, and none of those years passes the day count. Because she filed original returns, the Domestic route would still be open. However, she would then pay 5% of her highest year-end UK balances. If she had never filed at all, even that route would be closed. Our article on the Streamlined Domestic Offshore Procedures covers that route in detail.

How US UK Tax Experts can help

We prepare streamlined submissions for Americans who lived in the UK, including those who have now moved back. First, we map each year to where you lived and count the days. Next, we work out which route you qualify for and model both ways where both are open. Then we prepare the returns, FBARs and certification together, so your streamlined procedures after moving back to the US form one consistent package.

Our streamlined filing service covers the whole submission. We also prepare your final UK return from the same file, so the US and UK figures agree.

Conclusion

In summary, the streamlined procedures after moving back to the US depend on a rolling three-year window. One full year in the UK with no US abode can keep the Foreign route open, with no 5% penalty. Once that year drops out, the Domestic route needs original returns and charges 5%. Above all, act before the next return due date moves your UK years out of reach.
