Streamlined Filing With a UK Pension or SIPP: What Six FBAR Years Must Show

Six FBAR filings inside a streamlined submission are not six copies of a balance. Each one has to identify a single named account at a single financial institution and state its greatest value during that calendar year — not its year-end balance — converted into dollars at the Treasury rate for the last day of that year. For a UK pension the arithmetic is rarely the hard part. The hard part is deciding what counts as the account, and then making six years of answers consistent with the three tax returns filed alongside them.

This is written for an American living in Britain — the person on the Streamlined Foreign Offshore Procedure, who meets the non-residency requirement and therefore faces no miscellaneous offshore penalty. If you have moved back to the United States, the domestic track applies instead and the six years do a different job; our companion piece on an unreported UK ISA or SIPP in a domestic submission covers that case.

On the foreign track, the six FBAR years are evidence — not a penalty computation

The two streamlined tracks ask for the same documents. The IRS requires delinquent or amended returns for the most recent 3 years for which the return due date has passed, delinquent FBARs for the most recent 6 years for which the FBAR due date has passed, a signed Form 14653, and payment of the tax and interest. The non-residency requirement decides which track you are on: a US citizen or lawful permanent resident meets it if, in one or more of those three years, they had no US abode and were physically outside the United States for at least 330 full days.

What differs is what the six years are for. On the domestic track they feed a penalty base. On the foreign track there is no such penalty — the IRS's own terms are that a compliant filer "will not be subject to failure-to-file and failure-to-pay penalties, accuracy-related penalties, information return penalties, or FBAR penalties". So the six filings carry no arithmetic consequence of their own. Their job is purely evidentiary: they are the record of what you held and what it was worth, and they are the document set against which a reader will measure a certification you signed under penalties of perjury.

Two mechanical points catch people out. The FBARs go electronically through the FinCEN BSA E-Filing System, separately from the tax package; on the cover page you select "Other" as the reason for filing late and enter "Streamlined Filing Compliance Procedures" in the explanation box. The returns, by contrast, carry "Streamlined Foreign Offshore" in red at the top of the first page. The IRS page for taxpayers residing outside the United States sets out both. And one route that used to exist no longer does: the standalone Delinquent FBAR Submission Procedures have been withdrawn, taking with them the published assurance that went with filing late FBARs on their own. The IRS's current wording is simply that "Assertion of penalties depends on facts and circumstances."

First, settle this: a UK pension cannot reach the FBAR retirement exception

This is the single most common mistake in the material written about UK pensions and the FBAR, and it comes from reading one sentence without its definition.

The IRS FBAR page lists, among accounts that need not be reported, one "Held in a retirement plan of which you're a participant or beneficiary". Read alone, that appears to exempt any pension anywhere. It does not. The FinCEN line item filing instructions state the limit, and it is closed: the exception covers "a participant in or beneficiary of a retirement plan described in Internal Revenue Code section 401(a), 403(a), or 403(b)", with a separate carve-out for an IRA.

A UK self-invested personal pension is none of those four things. Neither is a UK workplace defined-contribution scheme, nor a final-salary scheme. Being a pension in Britain, and tax-favoured in Britain, does not put an arrangement on a list of plans defined by the United States Internal Revenue Code. The trigger is then the ordinary one: an FBAR is required once the aggregate value of your foreign accounts exceeds the $10,000 FBAR aggregate threshold at any time in the calendar year, and a current account you barely use and a pension you never think about can cross it between them.

Note what this does not decide. Whether US tax on growth inside the scheme is deferred under the treaty, and whether the scheme is a foreign trust requiring Forms 3520 and 3520-A, are separate questions with separate answers — both covered in our standing guide to US tax on UK pensions and SIPPs. Reportability is settled; taxability is argued.

What each of the six filings actually has to show

The FinCEN instructions set out the valuation in two steps, and the two steps use two different dates. That is not a drafting error, and copying a year-end figure across both is the commonest way a pension FBAR goes wrong.

• Step one is a value during the year. The maximum account value is "a reasonable approximation of the greatest value of currency or nonmonetary assets in the account during the calendar year". Not the December balance. For a pension invested in equities, a year with a spring peak and an autumn fall produces a maximum that the year-end statement never shows.
• Periodic statements may be relied on — conditionally. They may be used "provided that the statements fairly reflect the maximum account value during the calendar year". UK providers commonly issue annual statements to the scheme anniversary rather than to 31 December, so a single UK statement often does not fairly reflect a calendar-year maximum on its own. That is a reason to request valuations, not a reason to estimate.
• Step two converts at the year-end rate. The sterling maximum is converted using the Treasury rate for the last day of the calendar year — so a mid-year value is translated at a year-end rate. The instructions still direct filers to the retired Financial Management Service address; the rates now live with the Bureau of the Fiscal Service as the Treasury Reporting Rates of Exchange. If no Treasury rate is available, the instructions permit another verifiable rate provided you give its source.
• Round up, and never go below zero. Amounts are recorded in dollars "rounded up to the next whole dollar", and if a value comes out negative the instruction is to enter zero.
• Describe the account honestly. The account-type field offers Bank, Securities or Other; a pension is usually "Other" with a short description. The institution is the scheme administrator or provider, and the "account number or other designation" is frequently a member, policy or plan reference rather than anything that looks like a bank account number. A member number is a designation, and it belongs in the field.

There is also a record you must be able to produce afterwards: the name the account is held in, its number or designation, the institution's name and address, the type of account and the maximum value for each reporting period — kept for 5 years from April 15 of the year following the calendar year reported, or the date filed if later. For a six-year catch-up that matters more than it sounds, because the earliest years are precisely the ones a UK provider is slowest to evidence.

Is the SIPP one account, or one per fund?

One account. But the reason matters, because the same funds are treated differently a few lines later.

FinCEN's definition of a financial account expressly includes "shares in a mutual fund or similar pooled fund". So a UK open-ended investment company or unit trust held directly, in your own name, is itself a reportable account. Held inside a pension, it is not: the account is the one maintained with the SIPP administrator, and the funds are assets within it. The instruction on valuation points the same way — "if the filer had a financial interest in more than one account, each account must be valued separately" is a rule about accounts, not about holdings.

The practical consequences:

• Two SIPPs with two providers are two accounts. Three dormant workplace pots from three former employers are three more. Each gets its own entry and its own maximum value.
• A single SIPP holding thirty funds is one entry at one maximum value — the value of the whole account.
• Listing those thirty fund lines as thirty accounts is not merely untidy. Counting that way can push a filer past the 25-account point, at which the form stops asking for the account-by-account detail and takes a count instead. A filer who gets there by miscounting ends up disclosing less, inside a submission whose entire purpose is to look complete.

The funds then reappear elsewhere. Where a self-invested pension holds UK funds, the passive foreign investment company analysis may reach them individually on Form 8621 even though the FBAR treated the pension as one account. The two forms are asking different questions, and a file that is consistent on the FBAR can still be incomplete on the return.

When there is no balance to report

A final-salary promise has no account balance. There may be a transfer value or a cash equivalent on request, and there may be nothing at all until benefits come into payment.

The form provides for this: the "amount unknown" box exists, and its instruction is exact — check it "if the value of the account cannot be determined". Read that strictly. It is for a value that cannot be determined, not for one that is inconvenient to obtain. If the administrator will issue a cash equivalent transfer value on request, the value is determinable and the box is the wrong answer. If no figure exists for that year on any basis, the box is the right answer and a guess is the wrong one.

Whether a defined-benefit entitlement is a reportable account at all, in the years before anything is payable, turns on the scheme's own structure. That question is decided from the scheme rules before the six filings are drafted — not reverse-engineered afterwards to match what was filed.

How the six FBAR years have to line up with the three tax years

This is the reconciliation almost nobody writes down, and it is where a streamlined package is either coherent or visibly not.

Only three of the six FBAR years sit behind a tax return. In those overlapping years, the pension appears in up to three places: a maximum value on the FBAR, a value on Form 8938, and income on the Form 1040 if the position taken is that growth was currently taxable. Those are three statements about one asset, and they will be read together. A pension shown at a substantial value on the FBAR and at nil on Form 8938 for the same year is a contradiction that has to be either corrected or explained.

They will also, legitimately, be different numbers. The FBAR asks for a maximum during the year; other reporting commonly looks at a year-end figure. The same account can therefore carry two different values for the same year without either being wrong. Say so in the working papers. An unexplained difference looks like an error; an explained one looks like care.

The three older FBAR-only years work differently. There is no return behind them, so the FBAR is the only document you produce for that year and its maximum value is the entire record of the account's existence. Those years deserve more attention than they usually get, not less, because nothing else in the package corroborates them.

Form 14653 then certifies, under penalties of perjury, that all required FBARs have now been filed. Six reports built from whatever the provider happened to send, with a maximum value that is really a year-end balance and an "unknown" box papering over a gap, is not a set anyone should want to put their name to.

The order to do this in

1. List the accounts before valuing anything — every SIPP, every dormant workplace pot, every bank and building society account — and establish the legal form of each from the scheme documents.
2. Request calendar-year valuations, not anniversary statements, for all six years. Start early; this is the step that sets the timetable.
3. Value each account separately in sterling, then convert at the year-end Treasury rate for that year.
4. Settle the treaty and trust-form positions, and the fund-level PFIC analysis, before the returns are drafted.
5. Reconcile the six FBAR years against the three return years, document every difference, and draft the certification last.

Where we fit

We prepare these submissions end to end — the six FBARs account by account and year by year, the returns and the information returns that travel with them, the treaty and trust-form positions, and the Form 14653 narrative — with UK scheme documents read as UK documents rather than guessed at. Every filing is reviewed and signed off by a licensed professional: an IRS Enrolled Agent who is also ACCA-qualified, so the US filings and the UK position are looked at by one person rather than by two who never speak.

You can see what this work costs on our pricing page, model the numbers first with our calculators, or book a consultation to scope your own years. We do not file on your behalf: you sign and submit, once a licensed professional has reviewed what you are signing.
