IRS STREAMLINED FILING EXPERTS – PENALTY-FREE US TAX COMPLIANCE FOR EXPATS
Missed years of US tax returns while living in the UK? The IRS Streamlined Filing Compliance Procedures offer a legitimate, penalty-free route back to compliance for non-wilful filers. Our specialist US–UK tax advisors guide you through every step — from assessing your eligibility to final IRS submission.
Missed Years of US Tax Returns? There's a Penalty-Free Way Back.
Thousands of US citizens and Green Card holders living abroad have missed years of IRS tax filings — often without knowing they were required to file. If this sounds like you, the IRS Streamlined Filing Compliance Procedures offer a legitimate, penalty-free pathway to get back on track before the IRS finds you first.
The Streamlined Programme was created specifically for non-wilful non-compliance — meaning you genuinely didn't know you had to file, rather than deliberately avoiding your obligations. It allows you to submit overdue returns, pay any tax owed, and walk away without the life-altering penalties that would otherwise apply.
Our specialist US–UK tax advisors have guided hundreds of expats, dual citizens, and returning Americans through this process. We handle every aspect — from assessing your eligibility to preparing and submitting your returns — so you can resolve years of non-compliance with confidence.

The Procedures
Which Streamlined Procedure Applies to You?
There are three distinct routes under the IRS Streamlined Filing Programme. Your eligibility depends on where you live, your filing history, and the nature of your non-compliance.
Streamlined Foreign Offshore Procedure (SFOP)
Designed for US citizens and Green Card holders who have lived outside the US for at least one of the last three years. This is the most advantageous route — qualifying expats pay zero offshore penalties on previously undisclosed foreign assets and income.
Eligibility Criteria
0% Offshore Penalty
Full penalty waiver for qualifying expats
Streamlined Domestic Offshore Procedure (SDOP)
For US residents who failed to report foreign income or financial accounts held outside the United States. Rather than face the full suite of FBAR and FATCA penalties — which can reach hundreds of thousands of dollars — eligible filers pay a single miscellaneous 5% offshore penalty.
Eligibility Criteria
5% Miscellaneous Penalty
Instead of penalties up to $100K+ per violation
FBAR Delinquency Procedures
If you held foreign bank accounts exceeding $10,000 at any point and failed to file FBARs (FinCEN Form 114), you face penalties of up to $10,000 per account per year — or worse, criminal charges for wilful violations. The FBAR Delinquency Procedures allow eligible filers to catch up on six years of overdue FBAR filings without penalties.
Eligibility Criteria
No FBAR Penalty
For eligible non-wilful filers catching up on 6 years
Eligibility
Do You Qualify for the Streamlined Programme?
The key test is non-wilfulness. The IRS distinguishes between taxpayers who deliberately hid income or assets versus those who simply didn't know the rules. If your failure to file was an honest mistake, you are very likely eligible.
US Citizens & Green Card Holders Abroad
Americans living in the UK, Europe, or anywhere outside the US who didn't realise they had to keep filing US returns.
Dual Citizens Who Never Filed
People born with US citizenship (even if they've never lived there) who were unaware of the filing obligation.
Expats with Unreported Foreign Accounts
Those with UK or other foreign bank accounts, ISAs, or investments who didn't know FBAR or FATCA reporting was required.
Recently Discovered Obligations
People who recently learned (through an accountant, bank letter, or FATCA notice) that they needed to file US returns.
Who Cannot Use Streamlined?
The programme is not available to everyone. If the IRS is already investigating you, or if your non-compliance was deliberate, alternative voluntary disclosure programmes may be required.
If you're unsure whether your case qualifies, speak to us first. We assess every situation individually before recommending a route.
What Counts as Non-Wilful?
The IRS considers a failure non-wilful if it resulted from negligence, inadvertence, mistake, or a good-faith misunderstanding of the law. Common examples include:
Our Process
How We Get You Compliant
A structured, four-stage process — from initial assessment to full IRS resolution.
Eligibility Assessment
We start with a confidential consultation to understand your filing history, residency status, and the nature of your non-compliance. We determine which Streamlined procedure applies to you and outline what's required.
No commitment. No judgment. Just clarity.
Non-Willfulness Certification
The most critical element of a Streamlined submission is a signed certification explaining why your non-compliance was non-wilful. We draft this carefully, using precise IRS language, to clearly articulate your circumstances and protect your position.
A poorly drafted certification can jeopardise the entire submission.
Multi-Year Return Preparation
We prepare three years of overdue US tax returns (Form 1040) and six years of FBAR filings (FinCEN 114) where applicable. This includes all required schedules — foreign income, foreign tax credits, FATCA (Form 8938), and any relevant treaty positions.
Typically covers 3 years of returns and 6 years of FBARs.
Submission & IRS Liaison
We submit your complete Streamlined package directly to the IRS under the correct procedure. We handle all correspondence with the IRS and FinCEN on your behalf and remain your point of contact throughout the process until full resolution is confirmed.
You don't deal with the IRS. We do.

Frequently Asked Questions
Common Questions About the Streamlined Programme

You May Have More Options Than You Think
Many US citizens living in the UK discover their filing obligation years — sometimes decades — after moving abroad. The requirement to file US tax returns regardless of where you live is one of the most misunderstood aspects of US tax law, and the consequences of non-compliance can be severe.
The good news is that the IRS created the Streamlined Filing Compliance Procedures specifically for situations like yours. If your failure to file was genuinely unintentional, you can come forward now, submit your overdue returns, and resolve your position without the life-changing penalties that would otherwise apply.
Our specialist team works exclusively in US–UK cross-border taxation. We have guided hundreds of clients through the Streamlined Programme — from dual citizens who never knew they had to file, to expats who were simply given the wrong advice by a generalist accountant.

Streamlined Foreign Offshore Procedures (SFOP) →IRS Streamlined Filing — Frequently Asked Questions
What are the IRS Streamlined Filing Compliance Procedures?
They are an IRS programme that lets taxpayers whose failure to file was non-willful get back into compliance without the usual penalties. It is designed for people who did not know they had to file US returns while living abroad. You submit overdue returns and reports and certify that the non-compliance was not deliberate.
How many years of returns and FBARs do I need to file?
Under the Streamlined Foreign Offshore Procedures, you file amended or delinquent US tax returns for the most recent 3 years for which the due date has passed, and FBARs (FinCEN 114) for the most recent 6 years. You also submit a certification explaining that your prior non-compliance was non-willful.
Who qualifies as non-willful?
Non-willful conduct is behaviour due to negligence, inadvertence, mistake, or a good-faith misunderstanding of the law — not a deliberate attempt to evade tax. Many US citizens abroad genuinely never knew they had to file. Eligibility is fact-specific, so we assess your history honestly before recommending the streamlined route.
What is the difference between the Foreign and Domestic Offshore Procedures?
The Streamlined Foreign Offshore Procedures (SFOP) are for taxpayers who meet a non-residency test — broadly, US citizens who lived outside the US — and carry no offshore penalty for those who qualify. The Streamlined Domestic Offshore Procedures (SDOP) apply to US residents and include a miscellaneous offshore penalty. Most UK-based expats use the foreign procedure.
Will I have to pay penalties under the streamlined programme?
For those who qualify under the Foreign Offshore Procedures, the offshore penalties that would otherwise apply — including FBAR and information-return penalties — are waived, so you generally pay only any actual tax due plus interest. This is a major benefit compared with coming forward outside the programme or being discovered by the IRS.
What if the IRS has already contacted me about my returns?
The streamlined procedures are only available if the IRS has not already initiated an examination or investigation of your returns. If you have received IRS contact, different options may apply and timing is critical. Speak to a specialist before responding, so you preserve the best route back into compliance.
