US Tax Return Preparation for Expats: Elections You Missed

If your US returns were filed years late, the tax computation is rarely what decides the outcome — the election calendar is. Some elections remain fully available on a return filed a decade behind; others closed on the original due date and can now only be bought back through a discretionary IRS private letter ruling. Knowing which is which changes the number.

That distinction sits at the centre of competent US tax return preparation for expats, and it is the single subject most generalist preparers handle badly. A US citizen in London who has not filed since 2018 does not have one problem; she has two. The first is the arithmetic of six years of income. The second — usually larger — is that six years of elections were never made, and the regulations that govern late elections were written on the assumption that the underlying return was filed on time. At Jungle Tax we see catch-up engagements where the difference between a well-sequenced election strategy and a mechanical filing runs to six figures.

Why the election calendar decides a catch-up, not the tax calculation

US international tax is not a single computation. It is a series of computations, each switched on or off by a choice the taxpayer was supposed to signal on a return by a particular date. Exclude foreign earned income or claim credits? Treat a UK fund as a qualified electing fund or ride the excess distribution regime? Treat a UK limited company as a corporation or disregard it? Defer the growth inside a UK pension under the treaty or accrue it annually?

Each of those switches has its own clock. Some clocks are set by statute. Some are set by regulation. Some run from the original due date, some from the extended due date, and some — critically — do not run at all unless a return was actually filed on time. Once you have missed several years, the population of elections still available to you is materially smaller than the population available to a compliant filer, and no amount of skilful number-crunching restores them.

This is why we build the election map before we build the returns. The order matters: an election made in the earliest open year cascades through every later year, and a poorly chosen sequence can lock a client into a position for five further years.

What actually counts as an election?

An election is a formal, affirmative choice recognised by the Code or the regulations, usually signalled by filing a specific form, attaching a specific statement, or reporting in a specific manner. It is not the same as a position, a claim, or a method. The classification matters because relief for lateness is only available on the following lines:

• Statutory elections — the deadline is fixed by the Internal Revenue Code itself. The IRS cannot extend a statutory deadline by ruling. If Congress wrote the date, the date stands (subject only to the narrow automatic six-month rule below).
• Regulatory elections — the deadline is fixed by regulation, revenue procedure, notice or announcement. These are the elections the Commissioner has discretion to extend under Reg. 301.9100-3.
• Treaty elections and positions — governed by the treaty and by the disclosure rules of section 6114, typically evidenced on Form 8833.
• Reporting positions that merely look like elections — for example, the choice between Form 1116 credit baskets, or the sourcing of a pension distribution. These are positions, and they can normally be corrected on an amended or late-filed return within the ordinary statute.

A very large share of catch-up disputes are really arguments about which of those four boxes an item belongs in.

The two automatic reliefs — and the trap for late filers

Reg. 301.9100-2 grants relief without any ruling request, in two flavours, and the second contains the trap that defines a late-filing catch-up.

• The automatic 12-month extension. Available for a closed list of specified elections — among them the section 754 partnership basis-adjustment election, the section 444 tax-year election and the section 472 LIFO election. It runs for twelve months from the due date of the return for the election year, and, importantly, it does not require that the return was filed on time. Expats rarely benefit, because the listed elections are mostly domestic and entity-level.
• The automatic 6-month extension. Far broader in principle — it reaches both statutory and regulatory elections whose deadline is the due date of the return including extensions. But it is conditioned on the taxpayer having timely filed the return for the election year. A filer who is six years behind has, by definition, no timely-filed return for any of those years. The automatic six-month route is therefore closed to almost every catch-up client, on the first page of the regulation, before any discussion of merit begins.

That single condition is the reason a delinquent filer and a compliant filer with a clerical slip face completely different economics for the same missed election. It is also the reason we treat the first return filed in a catch-up as a strategic document rather than a formality.

When you need a private letter ruling — and what it costs in reality

Where automatic relief is unavailable and the election is regulatory, the remaining path is discretionary relief under Reg. 301.9100-3: a private letter ruling request to the IRS National Office. The taxpayer must establish two things — that they acted reasonably and in good faith, and that granting relief will not prejudice the interests of the government.

"Reasonably and in good faith" is generally satisfied where the taxpayer requested relief before the IRS discovered the failure, was prevented from acting by circumstances beyond their control, was unaware of the election despite exercising reasonable diligence, or reasonably relied on written IRS advice or on a qualified tax professional who failed to advise them. Relying on a UK-only accountant who never mentioned Form 8621 is, in our experience, a materially stronger fact pattern than relying on nobody at all.

"No prejudice to the government" is the harder test. Relief is refused where the taxpayer would end up in a better position than if the election had been timely — the IRS explicitly considers the time value of money — and it is refused where the taxpayer is using hindsight. If the years in question are now closed by the statute of limitations for the IRS but open in the taxpayer's favour, expect resistance. If markets moved in the intervening years such that the election is now obviously advantageous in a way it was not at the time, expect a hindsight objection.

Practically, a PLR is a multi-month process with a government user fee plus professional fees, and it is only worth commissioning where the arithmetic justifies it. For a HNW client with a substantial UK fund portfolio or a UK trading company, it frequently does. For a modest salary case, it almost never does.

Which elections survive a return filed years late?

Below is the map we work from. It is deliberately conservative: where an outcome depends on facts, we have said so rather than promised a result.

The section 911 ladder in detail

Because it is the election most expats assume they still have, section 911 deserves precision. The regulations create a descending ladder. The exclusion may be elected on a timely filed return including extensions; on a return amending a timely filed return; on a late-filed return filed within one year of the original due date, ignoring extensions; or on a return filed after all of those periods provided the taxpayer owes no federal income tax after the exclusion is taken into account, or owes tax but files before the IRS discovers the failure. Where a later return is used, the IRS requires a specific statement to be printed at the top of the first page of the Form 1040 referencing the relevant regulation. Miss every rung — the return is very late, tax is owed after the exclusion, and the IRS got there first — and only a private letter ruling remains. The IRS says so expressly on its guidance on choosing the foreign earned income exclusion.

Two further points that generalist pages omit. First, the "owes no tax after the exclusion" rung is where most UK-resident catch-ups actually land, because UK effective rates typically exceed US rates and foreign tax credits eliminate the residual liability anyway. Second, if the exclusion was previously revoked — for instance by claiming credits on excludable income in an earlier year — re-election is generally barred until the sixth tax year after revocation unless the IRS consents earlier. A sloppy first catch-up return can therefore silently disable section 911 for five subsequent years. See the Form 2555 instructions for the mechanics.

Why the FEIE is often the wrong election for a London filer anyway

Sophisticated clients are frequently relieved to learn that losing section 911 costs them very little. For a US citizen paying UK income tax at 45% plus the personal-allowance taper, the foreign tax credit almost always produces a better answer than the exclusion — and, unlike the exclusion, credits generate carryforwards, preserve the foreign-source income needed to absorb them, and do not disqualify the child tax credit or contaminate pension planning. The clients who genuinely need section 911 are those with low UK effective rates: individuals with substantial cross-border planning around non-UK workdays, or those whose UK liability is reduced by reliefs the US does not mirror.

How the streamlined programme interacts with missed elections

The Streamlined Foreign Offshore Procedures require three years of delinquent or amended returns and six years of FBARs, together with a signed non-willfulness certification on Form 14653. Crucially for this topic, the IRS instructions for taxpayers residing outside the United States expressly contemplate submitting the documentation required to request relief for a failure to make a timely election to defer income tax on the earnings of a foreign retirement plan under a treaty. In other words, the programme has a built-in election-repair mechanism for pensions — but only for that category, and only if the request is actually made in the submission.

Two consequences follow. First, a streamlined submission is the cheapest election-repair vehicle available to most expats, and it is wasted if the preparer files three clean returns and never raises the elections. Second, because streamlined covers only three years of returns, elections whose effect must begin in an earlier year sit outside the package and require separate handling. Sequencing the earliest streamlined year correctly is therefore load-bearing. We deal with this daily through our IRS streamlined filing practice.

The UK mirror: claims and elections HMRC will and won't accept late

The UK does not use the language of "9100 relief", but it has its own architecture of deadlines, and cross-border clients routinely trip both systems in the same year. The most common failure is assuming that because a US position can still be fixed, the UK one can too — or vice versa.

HMRC's own guidance is unusually candid about where the line falls: late claims are refused where the delay was caused by oversight, negligence or an agent's absence, and admitted where illness or comparable circumstances prevented the person both from claiming and from seeking help. The relevant manual page is SACM10040 in HMRC's Self Assessment Claims Manual. Note the asymmetry with the US test: the IRS will accept reliance on a professional who failed to advise; HMRC will generally not accept the absence or failure of an agent as a reason.

UK-side elections that most often go missing in a cross-border catch-up

• The four-year foreign income and gains claim for newly UK-resident individuals under the post-2025 regime, which must be claimed in the return for the year — a US-connected arrival who filed nothing has a genuine problem, not merely a computational one.
• Overseas workday relief, which depends on both eligibility and the mechanics being reflected correctly and in time.
• Elections affecting UK treatment of US retirement accounts, where the practical UK position on a Roth or a 401(k) can turn on how and when the position was taken.
• Capital gains elections such as main residence nominations, which have their own short statutory windows and no general late-relief mechanism.

The cross-border point is sharper than either side alone: an election made late in one country can create a mismatch that destroys foreign tax credit relief in the other, because credits depend on the two systems taxing the same income in overlapping periods. Repairing the US side in isolation is how clients end up with a technically compliant filing and double taxation.

A worked sequence for a US filer in London six years behind

1. Establish the filing posture first. Determine whether the facts genuinely support non-willfulness and therefore streamlined, or whether a different disclosure route is required. Every election decision downstream depends on this.
2. Map the elections year by year before drafting anything. Identify the earliest year in which each election must take effect, and check whether that year falls inside or outside the three streamlined years.
3. Fix the FEIE-versus-credit posture for the earliest open year. Because a revocation locks you out for five further years, this choice is effectively irreversible for the whole catch-up.
4. Deal with funds before pensions. PFIC exposure from UK unit trusts, OEICs and investment trusts is the most expensive and least forgiving area; establish whether a retroactive QEF route exists or whether the excess distribution regime and a purging election are the realistic outcome.
5. Make the pension treaty request inside the streamlined submission, with the supporting documentation, rather than assuming deferral was automatic.
6. Address entity classification. If there is a UK limited company, check the three-year-and-75-day window under Rev. Proc. 2009-41 before it closes, and model the section 962 alternative.
7. Only then price a private letter ruling for whatever remains. In most engagements one or two items survive to this stage, not ten.
8. Align the UK side in parallel, checking the four-year overpayment relief backstop and any late-claim discretion before those windows close.

The five mistakes we see most often

• Filing the returns first and thinking about elections afterwards. Once the returns are lodged, several routes — including the "before the IRS discovers it" rung of the section 911 ladder — are consumed.
• Assuming automatic relief applies. The six-month automatic extension requires a timely filed return; a delinquent filer does not have one.
• Claiming credits on excludable income in the first catch-up year and inadvertently revoking section 911 for the following five.
• Treating a UK pension's deferral as automatic. The treaty position exists, but it needs disclosing, and where the election was missed the streamlined route to repair it must be actively invoked.
• Ignoring the UK four-year wall. US relief that arrives in year five is worth much less if the corresponding UK overpayment relief claim expired in year four.

What this is worth

For a high-net-worth household with UK funds, a UK company and a pension, the gap between a mechanically prepared catch-up and an election-led one is not marginal. Retroactive QEF treatment can convert punitive excess-distribution tax and interest charges into ordinary income taxed once. Correct entity classification can eliminate years of Subpart F and GILTI inclusions. A properly invoked pension deferral request can remove annual accrual on a pension that was never distributed. None of that appears in the arithmetic — it appears in the calendar. Our wider library of cross-border guides covers the individual forms in detail.

If your US returns are years behind, the elections you did not make are almost certainly worth more than the income you did not report.
