The IRS Streamlined Filing Compliance Procedures are the IRS’s primary amnesty programme for US citizens and green card holders living abroad who failed to file required US tax returns, FBARs, and other compliance forms — not out of deliberate evasion, but simply because they were unaware of their obligations. For Americans living in the UK, this is one of the most important programmes to know about.
What Are the IRS Streamlined Filing Procedures?
The Streamlined Filing Compliance Procedures were introduced by the IRS in 2012 and significantly expanded in 2014. They allow qualifying taxpayers to come into compliance by filing a limited number of back returns and FBARs with reduced or zero penalties — provided the non-compliance was non-willful.
There are two versions of the programme:
- Streamlined Foreign Offshore Procedures (SFOP): For US persons residing outside the United States. Zero penalties for qualifying offshore residents.
- Streamlined Domestic Offshore Procedures (SDOP): For US persons residing inside the United States. A 5% miscellaneous offshore penalty applies.
For US expats in the UK, the SFOP is the applicable programme — and it offers the most generous terms.

Streamlined Foreign Offshore Procedures (SFOP): Eligibility
To qualify for the SFOP, you must meet all of the following requirements:
- Non-residency test: You have not been a US resident for tax purposes (filed a US return as a resident) in any of the most recent 3 years for which the US return due date has passed. For most expats in the UK who did not know they had to file, this is easily satisfied.
- Non-willfulness certification: Your failure to file was non-willful — i.e., it resulted from negligence, inadvertence, mistake, or a good-faith misunderstanding of US tax law, not from a deliberate attempt to evade tax. You must sign a statement certifying non-willfulness under penalties of perjury.
- You have not been contacted by the IRS about the years you are submitting. If the IRS is already examining your returns or has notified you of an examination, you do not qualify.
- You have not previously been subject to civil or criminal penalties for US tax compliance failures related to the years in question.
What Must Be Filed Under the SFOP?
- 3 years of US federal income tax returns (or amended returns) — the most recent 3 years for which the return due date (including extensions) has passed
- 6 years of FBARs (FinCEN Form 114) — the most recent 6 years for which the FBAR due date has passed
- All required information returns for those years — Form 8938 (FATCA), Form 5471 (foreign corporations), Form 8865 (foreign partnerships), Form 3520 (foreign trusts), Form 8833 (treaty positions), and others as applicable
- A non-willfulness certification statement — a signed statement explaining why your non-compliance was non-willful
- Payment of all taxes and interest — you must pay any tax and interest owed on the filed returns
Penalties Under the SFOP: Zero for Qualifying Offshore Residents
The SFOP provides complete penalty relief for qualifying applicants:
- Failure-to-file penalties: Waived entirely
- Failure-to-pay penalties: Waived entirely
- FBAR penalties: Zero — even for accounts that may have been reportable for many years
- Information return penalties (Form 8938, 5471, 8865, 3520): Waived entirely
- Accuracy-related penalties: Waived entirely
You must pay the actual tax and interest owed — the programme waives penalties but not the underlying tax liability. In many cases, because the Foreign Tax Credit or FEIE eliminates US tax on UK-source income, the actual tax owed under the SFOP is zero or very small — meaning the total cost of the programme can be just the professional fees to prepare the returns.
The Non-Willfulness Certification: The Most Important Element
The certification of non-willfulness is the cornerstone of the SFOP. A poorly drafted or inadequate certification is a significant risk — it can result in the IRS rejecting the submission, or worse, treating it as an admission of willful conduct. Key points:
- The certification must be specific and credible — not merely a formulaic statement
- It should explain how you came to understand your US filing obligations and why you did not previously file
- Common grounds include: believed renouncing tax residency was sufficient; relied on incorrect advice from a non-specialist accountant; did not know the US taxed citizens on worldwide income; was unaware of FBAR/FATCA requirements
- Vague, boilerplate certifications increase scrutiny risk
Who Is the SFOP Designed For?
The SFOP is most commonly used by:
- US citizens who moved abroad and were unaware of the “US citizens must file everywhere” rule
- Accidental Americans — people born in the US who moved abroad as children and have no meaningful connection to the US beyond citizenship
- Dual nationals who only recently discovered their US citizenship creates filing obligations
- Green card holders who left the US permanently and did not know they retained US tax obligations
- Expats who filed in prior years but missed reporting foreign accounts, pensions, or entities
How Long Does the SFOP Process Take?
The IRS does not have a published processing time for SFOP submissions. In practice, straightforward submissions are typically processed without audit or response. Complex submissions — those with large account balances, significant missed taxes, or complex non-willfulness narratives — may attract IRS scrutiny. Our team prepares submissions designed to minimise audit risk while being fully accurate.
What Happens If You Are Not Eligible for the SFOP?
If you do not qualify for the SFOP (e.g., because your non-compliance may have been willful, or because the IRS is already examining your returns), there are alternative compliance options:
- Delinquent FBAR Submission Procedures: For those with no unreported income but missing FBARs only
- Delinquent International Information Return Submission Procedures: For missing Forms 5471, 8865, 3520 etc. with reasonable cause
- Voluntary Disclosure Programme (VDP): For potentially willful non-compliance — a more structured disclosure with criminal protection but higher penalty exposure
Frequently Asked Questions
Can I use the SFOP if I paid some taxes in previous years?
Yes. The SFOP is available even if you filed some returns in the past — as long as you did not report the offshore accounts or income at issue. If you partially complied but had gaps (e.g., filed returns but did not file FBARs), the SFOP can address the gap years.
What if I owe zero US tax under the SFOP?
This is common for UK-based expats. Because UK income tax rates are typically equal to or higher than US rates, the Foreign Tax Credit often eliminates the US tax liability entirely for the Streamlined years. You still need to file the returns and FBARs — but the total financial cost may be just the professional preparation fees.
Do I need to continue filing after using the SFOP?
Yes. The SFOP brings you into compliance for past years, but your ongoing US filing obligations continue every year thereafter. Once compliant, most UK expats file annually with relatively low US tax liability thanks to the Foreign Tax Credit or FEIE. Our team can handle both the one-time SFOP submission and ongoing annual compliance.
Is the SFOP still available in 2026?
Yes. As of 2026, the Streamlined Foreign Offshore Procedures remain available. The IRS has indicated these procedures are available “for the present time” without announcing any planned end date. However, as FATCA reporting data flows continue to accumulate and the IRS gains more information about non-compliant taxpayers, the window for favourable treatment may narrow over time.
