Most guides about the US tax amnesty program for Americans abroad focus entirely on the submission itself — the returns, the FBARs, the non-wilfulness narrative, and the cost.
Very few explain what comes next.
The Streamlined submission resolves the historical non-compliance. It closes the gap between the years you missed and the present day. But it does not establish the ongoing compliance program that prevents a new gap from opening.
Many Americans who complete a Streamlined submission return to noncompliance within one or two years — simply because no one set up the annual filing framework before the catch-up was complete.
This guide explains exactly what post-Streamlined compliance looks like. It covers the annual forms, the filing deadlines, the ongoing cost, and the questions to ask your adviser before the submission closes.

The US tax amnesty program for Americans abroad is the informal name for the IRS Streamlined Foreign Offshore Procedures — the voluntary compliance route for non-wilful non-filers living outside the United States.
The program requires three years of US federal income tax returns and six years of FBAR filings. The taxpayer pays any additional tax and interest owed. No miscellaneous offshore penalty applies under the foreign track.
Once the submission is accepted, the historical gap is resolved. The taxpayer is current for the years covered by the submission.
But the clock keeps ticking. The following year’s return is due. The following year’s FBAR is due. And if those are not filed, a new gap opens immediately after the old one closes.
The Streamlined program is a one-time opportunity. A taxpayer who uses it to resolve historical non-compliance and then falls behind again cannot simply use it again.
The IRS treats a second period of non-compliance by a taxpayer who has already used the Streamlined program with considerably less sympathy. The non-wilful argument is much harder to make the second time around.
Establishing the annual compliance program before the Streamlined submission is complete is the single most important thing a specialist adviser can do for a post-Streamlined client.

This guide covers Americans in the UK who have completed — or are about to complete — a Streamlined submission and want to understand what their annual compliance program will look like.
It also covers those who completed a Streamlined submission years ago without establishing a proper ongoing program — and who want to know how to correct that position.
UK banks report account data for US persons to HMRC annually. HMRC passes that data to the IRS. The IRS matches it against filed US returns.
A taxpayer who filed a Streamlined submission covering years up to 2022 and then failed to file for 2023 and 2024 creates a visible gap in the IRS data within months of the submission’s completion.
The IRS has the account data. It has the prior submission. And it has no matching return for the subsequent years. That combination invites scrutiny.
Once a taxpayer has used the Streamlined program, they lose the option to use it again for subsequent non-compliance. The program is explicitly available only to those who have not previously used it for the same type of non-compliance.
Post-Streamlined non-compliance therefore carries the full penalty regime — failure-to-file penalties, failure-to-pay penalties, and potentially FBAR civil penalties — with no amnesty available.
Staying current after the Streamlined submission is not optional. It is the only path forward.
Our related guide on the adviser fees and scope of a Streamlined submission covers what the submission itself costs and includes.
The US tax year runs from 1 January to 31 December. The UK tax year runs from 6 April to 5 April. The two systems do not align, and managing both simultaneously requires a clear annual calendar.
Americans who are used to filing only a UK self-assessment — with a deadline of 31 January — often miss the US filing deadlines entirely. The US federal return deadline is 15 April, with an automatic extension to 15 October. The FBAR deadline is 15 April, with an automatic extension to 15 October.
Every US person living in the UK must file the following forms annually — regardless of whether tax is owed.
Form 1040 is the US federal income tax return. It covers worldwide income for the calendar year. Employment income, investment income, rental income, pension income, and self-employment income all appear on Form 1040. The Foreign Earned Income Exclusion or Foreign Tax Credit applies to eliminate or reduce the US tax on income already taxed in the UK.
FinCEN Form 114 — the FBAR — covers all foreign financial accounts where the aggregate balance exceeded $10,000 at any point during the calendar year. This includes UK current accounts, savings accounts, ISAs, SIPPs, and investment accounts. The FBAR deadline is 15 April with an automatic extension to 15 October. It is filed electronically through the FinCEN BSA E-Filing System.
Form 8938 — the FATCA statement — covers specified foreign financial assets above the applicable threshold. For a UK-resident single filer, the threshold is $200,000 at year-end or $300,000 at any point during the year. Form 8938 is filed with the federal return.
Form 8621 covers passive foreign investment company holdings. Every non-US fund — including UCITS funds inside an ISA or SIPP — requires Form 8621 annually. The mark-to-market or qualified electing fund election is made on this form. Missing Form 8621 leaves the statute of limitations open indefinitely on the entire US return.
The Article 17 treaty election covers UK pension funds — specifically SIPPs. This election must be made actively on each year’s US federal return. Without it, growth inside the SIPP may currently be taxable in the United States. The election is not automatic and does not persist from year to year without being made.
Form 5471 covers US persons who own 10 percent or more of a foreign corporation, including a UK limited company. A self-employed American who operates through a UK limited company must file Form 5471 annually. The $ 10,000-per-year penalty for a missing Form 5471 applies regardless of whether any tax is owed.
The US federal return deadline is 15 April. Americans abroad receive an automatic two-month extension to 15 June — simply by virtue of being outside the United States on the due date. A further extension to 15 October is available on request using Form 4868.
The FBAR deadline is 15 April, with an automatic extension to 15 October. No separate extension request is required for the FBAR — the extension is automatic.
The UK self-assessment deadline for online filing is 31 January. The specialist adviser prepares both the UK and US returns within the same filing window, ensuring the income figures are consistent across both jurisdictions.
A specialist adviser establishes the ongoing annual compliance program before the Streamlined submission is complete — not after. The scope of the annual program reflects the client’s full financial position, including income sources, investment accounts, pension structures, business interests, and PFIC holdings.
Every form required in the annual program is identified before the first post-Streamlined return is due. The adviser provides a clear list of what will be filed each year, the deadlines for each form, and the documents the client needs to provide. There are no surprises at the invoice stage.
The UK self-assessment and the US federal return cover overlapping periods — the UK tax year and the US calendar year share 10 months in common. The adviser prepares both returns simultaneously. The income figures on the UK self-assessment are the source data for the Schedule B and other income schedules on the US federal return. The UK income tax paid on the self-assessment generates the foreign tax credit on Form 1116.
This coordination is one of the most important services the adviser provides. A client who uses a UK accountant for the self-assessment and a US CPA for the federal return — without communication between them — risks inconsistent income figures across the two returns. The IRS and HMRC both receive data about the taxpayer. Inconsistencies attract attention.

https://www.irs.gov/individuals/international-taxpayers/us-citizens-and-resident-aliens-abroad
PFIC mark-to-market elections must be maintained year to year. The adviser obtains the year-end net asset value for each PFIC position from the wealth manager or investment platform and calculates the mark-to-market gain or loss annually. This data must be requested before the filing deadline — it is not automatically available from UK investment platforms in a US-compatible format.
The Article 17 treaty election for the SIPP must be made on each year’s US return. The adviser confirms the election is included in every annual return — it is one of the most commonly dropped items when a client switches advisers mid-year.

Amara is a US citizen. She has been a UK resident for nine years. She completed a Streamlined Foreign Offshore Procedures submission in 2023 — covering the three years of returns and six years of FBARs required by the program.
The submission resolved her historical non-compliance. The additional US tax and interest paid came to approximately £2,100. The adviser’s fee was £2,400. The submission was accepted without examination.
What Amara lacked was an annual compliance program for the years following the submission.
In 2024, Amara filed her UK self-assessment on time — as she always had. But she did not file a US federal return for the 2023 tax year. She did not file an FBAR for 2023. And she did not file Form 8621 for the two UCITS funds she held in her ISA.
By the time she contacted Jungle Tax in early 2025, she had missed the US return for one full year. She had also missed the 2024 FBAR. The statute of limitations on the 2023 US return remained open indefinitely because Form 8621 had not been filed.
The Streamlined program was no longer available to her for 2023 — she had already used it. Her 2023 and 2024 non-compliance carried the full penalty regime.
Jungle Tax prepared the 2023 US federal return — including Form 8621 for both PFIC positions and the Article 17 SIPP election — and filed it with a reasonable cause penalty abatement request for the late filing. The 2023 FBAR was also filed late, with a reasonable cause statement.
The 2024 return was prepared on time. An annual compliance program was established covering Form 1040, the FBAR, Form 8938, Form 8621 for two PFIC positions, and the Article 17 SIPP election — all of which were filed simultaneously with Amara’s UK self-assessment each year.
The annual cost of the ongoing program is £850. Amara now has complete visibility of what she owes, what gets filed, and when.

The most common post-Streamlined mistake is treating the submission as the end of the engagement rather than the beginning of an ongoing relationship. The adviser who prepares the Streamlined submission is the right person to establish the annual program — they already know the client’s full financial position. Waiting until after the submission closes to think about annual filing creates a gap from year one.
The Article 17 election must be made on every annual US federal return. It does not carry forward from year to year. A client who switches advisers — or who files their own return without specialist help — commonly misses this election in the first post-Streamlined year. As a result, SIPP growth becomes potentially taxable in the United States for that year.
PFIC mark-to-market elections require the year-end net asset value for each fund. UK investment platforms do not automatically provide this in the format the IRS requires. The adviser must request it from the platform or wealth manager before the filing deadline. Clients who do not know this requirement exists fail to provide the data, and the adviser cannot file Form 8621 correctly without it.
The FBAR deadline is 15 April — not 31 January. Americans accustomed to the UK self-assessment deadline assume the US filing deadline is later in the year. The automatic FBAR extension to 15 October is available — but it must be understood and used. A missed FBAR in a post-Streamlined year carries the full non-wilful penalty regime, with no amnesty available.

Some clients, having resolved the historical gap with a specialist, subsequently use a UK-only accountant for convenience and cost. A UK accountant without IRS Enrolled Agent or US CPA qualifications cannot prepare the US federal return correctly. Form 8621, the Article 17 election, and the foreign tax credit calculation all require specialist US tax knowledge. The cost of correcting a year of incorrectly prepared returns typically exceeds the annual savings from using a cheaper adviser.
Jungle Tax is a specialist US-UK cross-border tax advisory firm whose team includes IRS Enrolled Agents and UK-qualified tax practitioners. We establish the annual compliance program before each Streamlined submission closes — so that the first post-Streamlined return is filed on time, in full, and with all required forms included. We prepare the UK self-assessment and the US federal return simultaneously each year, with consistent income figures across both. We maintain PFIC mark-to-market elections by requesting year-end NAV data directly from the client’s investment platform. We make the Article 17 SIPP election on every annual return. We file the FBAR, Form 8938, and any applicable information returns as part of a single integrated annual filing program.

The US tax amnesty program for Americans abroad resolves the historical gap. What comes after it determines whether that resolution holds.
Three points matter most. First, the Streamlined program is a one-time opportunity. Post-Streamlined non-compliance carries the full penalty regime with no amnesty route available. Second, the annual compliance program must be established before the submission closes — not after. The adviser who knows the client’s full position is the right person to set it up. Third, the annual program is not just Form 1040 and the FBAR. Form 8621 (the Article 17 SIPP election), Form 8938, and Form 5471, here applicable, are all part of a complete post-Streamlined compliance framework.

Yes. The Streamlined submission resolves the historical gap — it does not end the annual filing obligation. Every US citizen and permanent resident must file a US federal return annually, regardless of where they live or whether any US tax is owed. The return covers worldwide income for the calendar year. Failing to file in the years following the Streamlined submission creates a new period of non-compliance — and the Streamlined program is not available a second time for the same type of non-compliance.
The core annual forms are Form 1040 (the US federal return), FinCEN Form 114 (the FBAR), and Form 8938 (FATCA), which is required when the applicable threshold is met. Additional forms depend on the client’s specific position. Form 8621 is required annually for each PFIC holding, including UCITS funds held in an ISA or SIPP. The Article 17 treaty election for a SIPP must be made on each year’s return. Form 5471 is required annually for US persons who own 10 percent or more of a foreign corporation. A specialist adviser identifies every required form before the first post-Streamlined return is due.
No. The Streamlined program is explicitly available only to taxpayers who have not previously used it for the same type of non-compliance. A taxpayer who completes a Streamlined submission and then falls behind on annual filing cannot use the program again for those subsequent years. Post-Streamlined non-compliance carries the full IRS penalty regime — failure to file, failure to pay, and FBAR civil penalties — with no amnesty route available. This is why establishing the annual compliance program before the submission closes is so important.
The Article 17 treaty election is a claim made on the US federal return that allows a UK pension — specifically a SIPP — to receive deferred US tax treatment on its growth. Without the election, growth inside the SIPP may currently be taxable in the United States. The election must be made actively on each year’s US federal return — it does not carry forward automatically from year to year. A specialist adviser includes the Article 17 election as a standard item on every annual return for clients who hold a SIPP.
The FBAR obligation continues annually. Every US person who holds foreign financial accounts with an aggregate balance exceeding $10,000 at any point during the calendar year must file FinCEN Form 114. This includes UK current accounts, savings accounts, ISAs, SIPPs, and investment accounts. The FBAR deadline is 15 April with an automatic extension to 15 October. Missing the FBAR in any post-Streamlined year carries the full non-wilful penalty regime — up to $10,000 per account per year — with no Streamlined amnesty available.
Annual costs depend on the complexity of the client’s financial position. For a straightforward UK-based American — employment income, personal accounts, no investment portfolio or pension complications — annual fees typically range from £500 to £1,200. For clients with investment portfolios, PFIC positions, a SIPP requiring the Article 17 election, and a UK limited company requiring Form 5471, annual fees typically range from £2,000 to £4,000. A specialist adviser provides a clear written scope and fixed annual fee before the first post-Streamlined return is prepared.
