Which streamlined route fits you - if any?
The streamlined procedures are the IRS's main road back for people who fell behind on US filings while living ordinary lives abroad or holding ordinary foreign accounts at home. There are two routes with very different price tags, and eligibility turns on a handful of questions: whether your conduct was non-willful, whether an examination has already started, where you lived, and what you previously filed. This checker asks those questions in the same order a professional would, then names the likely route.
Two routes, two very different price tags
The Streamlined Foreign Offshore route serves people who meet a non-residency test: for citizens and green card holders, at least one of the last three years with no US home and 330 or more full days outside the United States. Eligible filers who complete the package properly face no failure-to-file, failure-to-pay, accuracy-related, information return, or FBAR penalties. That is the best deal in the whole compliance landscape, which is why eligibility for it gets checked first.
The Streamlined Domestic Offshore route covers non-willful filers who do not meet that test. It requires previously filed returns for each of the last three years, and it carries a real cost: a miscellaneous offshore penalty of 5% of the highest aggregate year-end value of the relevant foreign accounts. Calling both routes penalty-free is the single most common error we hear, and the word streamlined does a lot of misleading work in it.
What both routes have in common
Each package contains the same three elements: three years of returns, original or amended as the route requires, six years of FBARs, and a signed certification that the failures were non-willful. Non-willful means conduct due to negligence, inadvertence, or mistake, or a good-faith misunderstanding of the law. The certification is the heart of the submission, because it is where your story gets told once, in writing, under penalty of perjury.
Both routes also share a hard gate: they close once the IRS has begun a civil examination of any of your years. That is why timing dominates this whole area. The routes reward the person who moves before the letter arrives, and the checker above treats an open examination as the first question for exactly that reason.
What the checker cannot see
Six questions cannot weigh how your facts read: what the accounts were for, what advice you had, what the paper trail shows. Nor can they compute the Domestic route's 5% base, which needs year-end values across the covered period for every relevant account. Treat the result here as the shape of the answer, not the answer itself.
If the result points at either route, the next step is a scoping conversation, not a filing. The wrong route, or a thin certification, spends the best facts you have on the wrong submission. This page is general information, not personal tax advice; take advice on your own position from a qualified US-UK adviser before acting on it.
Which streamlined route fits you - if any?
Any open IRS examination, for any year, closes the streamlined routes.
Streamlined is only for non-willful conduct. Deliberate concealment needs different advice.
This is the non-residency test for the Foreign route, for citizens and green card holders.
Likely route
Streamlined Foreign Offshore
File 3 years of returns and 6 years of FBARs with a non-willfulness certification. Eligible filers who follow the instructions face no failure-to-file, accuracy, information return, or FBAR penalties.
Remember
This is a first-pass estimate, not advice
Eligibility turns on facts a six-question tool cannot see. Confirm the route before filing anything.
Assumptions
- Answers describe your last three tax years and current facts; older years can change the analysis.
- The non-residency test shown applies to US citizens and green card holders; different tests apply to others.
- The Domestic route's 5% penalty base is the highest aggregate year-end value of the relevant foreign accounts and assets.
- No IRS contact beyond routine notices is assumed; an open examination changes everything.
- This tool classifies routes only - it does not compute tax, interest or the penalty amount itself.

Only the Foreign route. Eligible non-willful filers on the Streamlined Foreign Offshore route face no failure-to-file, accuracy, information return, or FBAR penalties. The Domestic route charges 5% of the highest aggregate year-end value of the relevant foreign accounts. The route, not the word streamlined, decides the cost.
The IRS defines it as conduct due to negligence, inadvertence, or mistake, or conduct resulting from a good-faith misunderstanding of the law's requirements. Most people who simply never knew about FBARs or foreign income rules fit comfortably. Deliberate concealment, moved money and ignored advice point the other way.
As a citizen or green card holder, you need at least one year among the last three with no US abode and 330 or more full days physically outside the United States. A settled life in the UK usually clears it, but count the travel days properly before relying on that.
A routine notice is not necessarily fatal, but an opened civil examination of any year closes both routes. That line matters enormously, so if anything from the IRS has arrived, get the letter read by an adviser before deciding your route or filing anything in response.
Three years of tax returns, six years of FBARs, and a certification on the applicable form explaining the non-willful failures, submitted together as one package with any tax and interest due. The Domestic route adds the 5% penalty computation. Completeness and consistency across the package matter as much as any single form.
Broadly yes: green card holders use the same non-residency test as citizens for the Foreign route, and the same non-willfulness standard throughout. Their positions often carry extra angles, such as treaty residence claims, so the route analysis deserves particular care before anything is filed.
