Does the Streamlined Foreign Offshore procedure cover LTIP vestings I forgot to report?

Yes. The procedure brings the most recent three years of returns and six years of FBARs into compliance, so any LTIP vesting that fell inside the three-year income window is reported as ordinary income on those returns. Vestings outside that window are not re-opened for income, but the share-plan account they sit in may still need to appear in the six-year FBAR history. The whole point of the route is to capture this kind of omitted foreign income without willful penalties.

Is my UK LTIP taxed by the US at grant or at vest?

For the common restricted-unit style of LTIP, the US generally taxes the award at vest, when the forfeiture risk lapses and the shares become deliverable, on the fair market value at that date as ordinary compensation. The grant itself is usually a conditional promise with nothing to tax. Terms vary, though, and an award structured differently can change the taxing point, so the plan rules and award agreement should be checked against your facts.

Do I have to file an FBAR for the account holding my vested LTIP shares?

If the vested shares sit in a foreign share-plan or brokerage account, that account counts toward the FBAR aggregate. You must file FinCEN Form 114 when the combined value of all your foreign financial accounts exceeds $10,000 at any point in the year, so the share-plan balance added to everyday banking can trigger the filing. The FBAR reports the maximum value of each account during the year.

Can the Foreign Tax Credit fully eliminate double tax on an LTIP vesting?

Often it can, because UK PAYE on a vesting is usually creditable against the US tax on the same foreign-source compensation, and where the UK rate is at or above the US rate the credit can remove the US liability entirely. The relief depends on sourcing the income correctly and matching the credit to the right year, which the UK and US tax-year mismatch can complicate. Excess credits can generally carry back one year and forward ten.

What is the 330-day test for Streamlined Foreign Offshore?

For a US citizen, the non-residency requirement is generally met by being physically outside the United States for at least 330 full days in at least one of the three covered years and not maintaining a US abode. Meeting it is what qualifies you for the Foreign version of the procedure, which carries no miscellaneous offshore penalty. Check your travel records carefully against the current rules, as the test is strict.

Do I owe US capital gains tax when I sell shares that already vested?

Only on the movement in value after vesting. Your cost basis equals the fair market value already taxed as ordinary income at vest, so you are not taxed twice on that amount; only the gain or loss between the vesting date and the sale date is a capital item. The holding period runs from the vesting date, and any sale inside the Streamlined covered years must be reported on those returns.

Streamlined Foreign Offshore and a UK LTIP

A US citizen who has spent years working for a British employer often collects a long-term incentive plan award without ever connecting it to a US tax return. The shares vest, they land in a UK share-plan account, PAYE takes its slice, and the matter feels closed on this side of the Atlantic. It is not. Every vesting is a US income event, and for an American who has fallen behind on filings the Streamlined Foreign Offshore procedure is usually the cleanest way back into compliance. This article walks through how a UK LTIP interacts with that route, where the timing traps sit, and what actually goes into the submission.

The core difficulty is timing. A UK LTIP and the US tax code do not always recognise income in the same moment, and when they drift apart the foreign tax credit that should prevent double taxation can land in the wrong year. Before the certification is even drafted, the vestings have to be sourced, valued and matched correctly across several years of account history. Get that right and the rest of the package tends to fall into place.

How does a UK long-term incentive plan actually work?

An LTIP is an umbrella term rather than a single instrument. In most UK listed and larger private companies it takes the form of a conditional share award or a nil-cost option: the employee is promised a number of shares that will be delivered only if they stay employed for a vesting period, typically three years, and only if performance conditions attached to the award are met. Those conditions might be total shareholder return against a comparator group, earnings growth, or a blend of financial and strategic targets. Until the conditions are tested, the employee owns nothing outright — the award is a contingent right, not a holding of shares.

When the vesting date arrives and the conditions are satisfied, the award converts into actual shares, often net of a number sold or withheld to cover the UK PAYE and National Insurance due. The remaining shares usually settle into a nominee or share-plan account run by the employer's administrator, and from that point the employee holds real, saleable stock. The structure matters for US purposes because the US cares a great deal about the moment ownership and unconditional value pass to the employee, and an LTIP is deliberately built so that moment is delayed.

Does the US tax an LTIP at grant or at vest?

For the typical restricted-unit style of LTIP, the US generally taxes the award at vest, not at grant. The grant is a mere promise subject to a substantial risk of forfeiture, so there is nothing to tax when it is made. When the forfeiture risk lapses and the shares become deliverable, the fair market value at that date is ordinary compensation income, reported on the Form 1040 for the year the vesting falls into. This mirrors how the US treats restricted stock units generally, and it is why each tranche of an LTIP has to be picked up separately rather than lumped together at the end.

The qualification matters because terms vary. Section 83 of the Internal Revenue Code governs property transferred in connection with services, and a Section 83(b) election to accelerate the charge to grant is only available where actual property is transferred up front — which is usually not the case for a conditional LTIP that delivers nothing until vest. If a particular award instead transfers restricted shares at grant, or is structured as a true nil-cost option, the analysis can shift and the taxing point can move. The only safe approach is to read the specific plan rules and award agreement rather than assume the standard pattern applies to your award.

Why does the US-UK timing of an LTIP so often mismatch?

The UK normally taxes the same vesting through PAYE as employment income at the moment the shares are delivered, which looks as though it should line up neatly with the US charge at vest. The friction comes from the calendar. The UK tax year runs 6 April to 5 April; the US tax year is the calendar year. A vesting in, say, February falls into one UK tax year and a different US year, so the UK tax and the US income can be reported in periods that do not share a boundary. Add exchange-rate movement between the vesting date and the date UK tax is actually settled, and the two computations can diverge even though they describe the same event.

There is a second, deeper mismatch where residency or duty location shifts during the vesting period. The UK may apportion part of an award to the period over which it was earned, and the US sources compensation by where the services were performed. An American who moved mid-vesting, or who travelled extensively for work, can find that a single tranche is part US-source and part foreign-source. That split drives directly into the foreign tax credit calculation, so it has to be worked out before any credit is claimed rather than assumed away.

A worked example: one LTIP tranche vesting

Take a single tranche to see the mechanics. Assume 1,000 shares vest on a day the share price is £8.00, so the UK treats £8,000 as employment income and the US treats the same vesting as ordinary compensation. Assume an exchange rate of $1.27 to the pound on the vesting date, and that the UK collects income tax at a 40% marginal rate through PAYE. The figures below are illustrative only — rates, bands and exchange rates change, and your own marginal position will differ.

Shares vesting: 1,000 at £8.00 = £8,000 of employment income in the UK, and the same value as US ordinary compensation.
US income reported: £8,000 converted at $1.27 = $10,160 of ordinary income on the Form 1040 for the vesting year.
UK income tax at 40%: £3,200, which converts at $1.27 to roughly $4,064 of creditable foreign tax paid.
US tax on the vesting, assuming a 24% marginal rate: about $2,438 before any credit.
Foreign tax credit: the $4,064 of UK tax offsets the $2,438 of US tax on this foreign-source income, removing the US tax on the tranche and leaving excess credit to carry.

The headline result — no residual US tax on the vesting — is common for employees taxed at high UK rates, but the excess credit is only useful if it can be matched to other foreign-source general-category income and claimed in a period the US will accept. A credit generated in a year the income is not recognised for US purposes, or sitting in the wrong category, does not help. This is exactly where careful sourcing and year-matching earn their keep, and why the example is a starting point rather than a formula.

How does the Foreign Tax Credit relieve the double tax?

The foreign tax credit, claimed on Form 1116, is the main tool for stopping the same LTIP vesting being taxed in full twice. In broad terms it lets a US taxpayer offset US tax on foreign-source income with foreign income tax paid on that same income, up to a limit calculated by category. For LTIP compensation earned while working in the UK, the income is usually foreign-source general-category income, and UK PAYE on the vesting is the creditable foreign tax. Where the UK rate is at or above the US rate, the credit commonly wipes out the US liability on the tranche entirely.

The relief is neither automatic nor unconditional. The income and the tax have to be characterised and sourced compatibly, and the credit has to fall in a period the US recognises the income. Where the UK tax year straddles the US year, taxpayers sometimes need to track when the foreign tax accrues against when it is paid, and may consider the accrual method to align them. Excess credits can generally carry back one year and forward ten, which cushions a mismatch but does not cure a fundamental sourcing error. None of this substitutes for advice on your own dates and numbers.

Which accounts and holdings go on the FBAR and Form 8938?

Once an LTIP vests, the shares usually sit in a UK or offshore share-plan or brokerage account, and that account is a foreign financial account. If the aggregate value of all your foreign financial accounts tops $10,000 at any point in the year — counting ordinary current accounts, savings and the share-plan account together — you must file an FBAR, FinCEN Form 114, reporting each account's maximum value. Form 8938 is a separate obligation filed with the Form 1040; it reports specified foreign financial assets above thresholds that are far higher for Americans living abroad than for those in the States, and it can capture both the share-plan account and, in some cases, the underlying shares. The two forms overlap without being interchangeable, so an asset can be reportable on both. Confirm the current thresholds and the living-abroad tests on IRS.gov, because they are indexed and the definitions are detailed.

How is a later sale of the vested shares taxed?

When the vested shares are eventually sold, the US treats the sale as a capital gain or loss measured against a cost basis equal to the fair market value already taxed as income at vest — so the amount picked up as ordinary compensation becomes your basis, only the price movement between vesting and sale is taxed again, and the holding period runs from the vesting date. The UK runs its own capital gains computation on the same disposal, with its own base cost and in sterling, so currency movement alone can produce a US gain and a UK gain of different sizes on one sale. Where both countries tax the gain, a further foreign tax credit analysis applies. For a Streamlined submission the narrower point is this: any sale that happened inside the covered years has to be reported on the amended or delinquent returns, not just the vestings themselves.

How does the Streamlined Foreign Offshore procedure capture the vestings?

The Streamlined Foreign Offshore procedure is built for exactly this situation: a US person living abroad whose failure to report foreign income and accounts was non-willful. It requires three years of tax returns — the most recent three for which the filing deadline has passed — filed or amended to include the omitted income, together with six years of FBARs. For an LTIP that vests in tranches, that means every vesting falling inside the three-year return window is picked up as income, and every year the share-plan account pushed total foreign accounts over $10,000 is reported across the six-year FBAR window. Because the vestings are staggered, the two windows rarely line up tidily: a tranche that vested four years ago sits outside the income window, yet its account balance may still belong in the FBAR history.

Eligibility turns on the non-residency test. For a US citizen that generally means being physically outside the United States for at least 330 full days in at least one of the three covered years and not having a US abode. You must also not already be under IRS examination, and the failure must genuinely be non-willful. The reward for meeting the foreign test is significant — the procedure carries no miscellaneous offshore penalty — which is a large part of why it is the preferred route back into compliance for Americans abroad. Mapping each vesting date, account balance and sale against the two timelines is the real work, and it is far easier to do once, properly, than to unpick after the package is filed.

What does the non-willful certification have to say?

The certification is made on Form 14653, and it is the heart of the submission. You must state, under penalty of perjury, the specific facts explaining why the LTIP income and accounts went unreported and why that failure was non-willful — inadvertence, a genuine misunderstanding of the rules, or reasonable reliance on advice that proved wrong. Generic language does not persuade; a strong certification for an equity-comp case explains the employee's assumption that PAYE on the vesting settled everything, the absence of any US adviser during the relevant years, and the moment the US obligation came to light. It must be consistent with the returns and FBARs filed alongside it, because a narrative that contradicts the numbers invites exactly the scrutiny the procedure is meant to avoid. Since the statement is signed under penalty of perjury and the willfulness line is fact-sensitive, this is where professional input matters most.

Your Streamlined Foreign Offshore equity-comp checklist

Before assembling the submission, work methodically through the moving parts. The checklist below is a starting framework, not a substitute for advice tailored to your award terms and residency history.

Collect every LTIP award agreement and plan rule, and record each grant and vesting date.
Value each vested tranche at its vesting-date fair market value and convert to US dollars at the appropriate rate.
Confirm whether each vesting is foreign-source or split-source based on where you worked during the vesting period.
Gather UK PAYE and payslip records showing the tax withheld on each vesting, for the foreign tax credit.
List every foreign financial account, including the share-plan and nominee account, with maximum values for each of the six FBAR years.
Identify any sales of vested shares inside the covered years and compute the capital gain or loss against vest-date basis.
Check the non-residency and 330-day test against your travel records for the three covered years.
Draft the Form 14653 narrative so that it matches the income and account figures exactly.

A UK long-term incentive plan is one of the most common reasons an otherwise diligent American in Britain ends up behind on US filings. The award feels local, the tax feels paid, and the US dimension stays invisible until something — a mortgage application, a new adviser, a letter from the bank about FATCA — surfaces it. The Streamlined Foreign Offshore procedure exists precisely so that this kind of honest oversight can be corrected without the penalties reserved for willful conduct.

The work that makes or breaks the submission is done before the forms are signed: dating and valuing each vesting, sourcing it correctly, matching the foreign tax credit to the right year, and tracing the share-plan account across six years of FBARs. Do that carefully and the Streamlined Foreign Offshore filing becomes a clean, defensible record rather than a source of further questions. Because the timing and willfulness analysis is so fact-specific, confirm the current rules on IRS.gov and take advice from a cross-border specialist before you file.
