Can I use foreign tax credit carryovers from my working years during a career break?

Only within the same category. Publication 514 allows unused foreign taxes to be carried back one year and forward ten years, but each category is computed separately. Excess UK tax on salary is general category and cannot offset US tax on passive interest and dividends. Also, UK tax on salary you excluded under the foreign earned income exclusion never creates a credit or carryover at all.

Do I need to file an FBAR if I had no income during my break?

Yes, if your foreign accounts together exceeded $10,000 at any time in the calendar year. The FBAR is based on account balances, not income. It is filed with FinCEN through the BSA E-Filing System, due 15 April with an automatic extension to 15 October. Late FBARs are filed through the same system with a reason for late filing, or within the Streamlined procedures.

Which catch-up route is best for missed US tax returns after returning to work?

It depends on the gap. One or two missing years with full information returns may suit late filing with a reasonable cause statement. Where earlier years also have omissions, the Streamlined Foreign Offshore Procedures let non-wilful taxpayers living abroad file three years of returns and six years of FBARs with no penalty, provided they meet the 330-day non-residency test and sign Form 14653.

Missed US Tax Returns During a London Career Break

Q: Do I have to file a US tax return if I only had investment income?

Yes, if your worldwide gross income reached the filing threshold for your filing status. Interest, dividends and gains from UK accounts all count. For 2025, IRS Publication 501 sets the threshold at $15,750 for a single filer under 65 and just $5 for married filing separately. Owing no US tax after foreign tax credits does not remove the obligation to file the return and its attached information returns.

Q: Does the foreign earned income exclusion cover UK dividends and interest?

No. The Form 2555 instructions state that foreign earned income does not include interest, ordinary dividends, capital gains, pensions or annuities. In a career-break year funded by investment income, the exclusion has nothing to exclude. The relief against double taxation on that income is the foreign tax credit on Form 1116, claimed in the passive category against UK tax paid on the same income.

Q: Do I need a UK Self Assessment return during a career break in London?

Usually, if you remain UK resident and live on investment income. Without PAYE salary, interest, dividends and gains are often paid gross. GOV.UK says you must tell HMRC if dividends exceed your unused Personal Allowance plus the £500 dividend allowance, and savings interest above your available allowances is taxable. Capital gains on investment sales are also reported through Self Assessment.

Missed US tax returns during a career break in London are usually caused by one assumption: no salary, no filing. That assumption is wrong. A US citizen must file whenever worldwide gross income reaches the filing threshold for their filing status, and UK interest, dividends and capital gains all count towards that test. Separately, the FBAR and, where the thresholds are met, Form 8938 remain due whatever your income was, because they are driven by account balances rather than earnings.

In the returns we prepare for American bankers, lawyers and executives in London, the sabbatical year is one of the most common gaps we find in an otherwise clean filing history. The client stepped away from a City role for twelve or eighteen months, lived on savings and a portfolio, and simply stopped sending anything to the IRS. The good news is that this gap is almost always fixable, often with little or no US tax due once UK tax is credited. The bad news is that it rarely fixes itself, and the longer it runs the more forms pile up. This guide explains what was actually due, why the usual expat reliefs behave differently in a year without earnings, what the UK expects of you while you stay resident, and how to catch up cleanly when you return to work.

Do you need to file a US tax return if you had no salary?

Yes, if your gross income met the threshold. The IRS defines gross income in Publication 501 (https://www.irs.gov/publications/p501) as all income you receive in the form of money, goods, property and services that is not exempt from tax, including income from sources outside the United States. Salary is just one component. Interest from a UK current or savings account, dividends from UK shares or funds, gains on selling investments, rental profit and consulting fees all go into the same calculation.

For the 2025 tax year, Publication 501 sets the threshold at $15,750 for a single filer under 65 and $31,500 for a married couple filing jointly where both are under 65. For married filing separately, the threshold is just $5, which catches many Americans married to British spouses, because they often file separately rather than electing to treat a non-US spouse as resident. Publication 54 (https://www.irs.gov/publications/p54) confirms that citizens abroad apply these thresholds to worldwide gross income.

For a former banker living on a portfolio of any meaningful size, that threshold is crossed quickly. A cash pile earning UK interest at prevailing rates, plus dividends and the occasional disposal to fund living costs, will typically put gross income well above the line. Gains on disposals count as gross income too, so a year of selling investments to fund the break can push you over even when you feel you have been living off capital.

Owing no US tax does not remove the obligation to file. Many of the returns we prepare for career-break years show a small or nil US liability once UK tax is credited, but the return still had to be filed, and the information returns attached to it still had to be completed.

Why do the FBAR and Form 8938 continue during a career break?

The FBAR is an account-balance report, not an income report. FinCEN Form 114 is required if the aggregate value of your foreign financial accounts exceeded $10,000 at any time during the calendar year. The IRS comparison page (https://www.irs.gov/businesses/comparison-of-form-8938-and-fbar-requirements) confirms it is due on 15 April with an automatic extension to 15 October and is filed electronically through FinCEN's BSA E-Filing System at https://bsaefiling.fincen.treas.gov, not with your tax return. Someone living on savings almost by definition has large foreign balances, so the FBAR is very rarely optional in a career-break year.

Form 8938 is the IRS's own foreign asset statement, attached to Form 1040. For taxpayers living abroad, the thresholds are more than $200,000 at year-end or more than $300,000 at any time for single filers and married filing separately, and more than $400,000 at year-end or more than $600,000 at any time for joint filers. Form 8938 is not required if you have no income tax return obligation, but that exception rarely helps the people we see, because the investment income that funds the break usually creates the filing obligation anyway.

FBAR: required if all foreign accounts together exceeded $10,000 at any point in the calendar year, regardless of income.
Form 8938: required with your Form 1040 if specified foreign financial assets exceed the abroad thresholds and you have a filing obligation.
Accounts that count typically include UK current and savings accounts, brokerage and ISA accounts, and cash held on investment platforms.
Joint accounts with a spouse are generally reported at their full value by each US owner, which often surprises couples where only one partner is American.

Does the foreign earned income exclusion help in a year without earnings?

No. The foreign earned income exclusion, claimed on Form 2555, is limited to earned income: wages, salaries, professional fees and other pay for personal services performed abroad. The Form 2555 instructions (https://www.irs.gov/instructions/i2555) state expressly that foreign earned income does not include interest, ordinary dividends, capital gains, pensions or annuities. In a year funded by investment income, the exclusion has nothing to exclude.

This is the single biggest misunderstanding we see in career-break files. A client who claimed the exclusion for years while working in London assumes the same mechanism shields them during the break. It does not. Every pound of UK interest and dividends is fully within the US tax base, and the only relief against double taxation is the foreign tax credit, discussed below.

There is also a timing interaction to watch. Once chosen, the exclusion remains in effect for that year and all later years unless you revoke it, according to the IRS page on choosing the exclusion (https://www.irs.gov/individuals/international-taxpayers/choosing-the-foreign-earned-income-exclusion). The Form 2555 instructions explain that revocation is made by attaching a statement to the return for the first year you do not want the exclusion, and that if you revoke, you cannot claim it again for your next five tax years without IRS approval. The same IRS page warns that taking a credit or deduction for foreign taxes on income you excluded revokes the election from that year. For someone returning to a London salary after the break, those rules decide whether the exclusion or the foreign tax credit is the better long-term structure, so the choice deserves care before the first catch-up return is filed.

How does the foreign tax credit work when your income is mainly passive?

The foreign tax credit, claimed on Form 1116, lets you offset UK income tax and capital gains tax paid on foreign-source income against the US tax on the same income. The key concept for a career-break year is the separate limitation category. The Form 1116 instructions (https://www.irs.gov/instructions/i1116) define passive category income as dividends, interest, rents, royalties, annuities and gains from property that produces that type of income. Salary, by contrast, falls in the general category. The credit is computed separately for each category.

Publication 514 (https://www.irs.gov/publications/p514) sets the carryover rule: unused foreign taxes are first carried back one year and then forward for the ten years after the year in which they arose. Carryovers stay within their category. That creates a gap almost nobody explains: excess UK tax from your high-earning salary years is general category, and it cannot be used against US tax on passive interest and dividends in your career-break year. Clients are often surprised to find that a large carryover on their last working return does nothing for the sabbatical.

Two further points matter. First, Publication 514 states that you cannot take a credit for foreign taxes paid on income you excluded under the foreign earned income exclusion, so if you used the exclusion in your working years, the UK tax on that excluded salary never generated a carryover in the first place. Second, passive income taxed at UK higher or additional rates usually generates enough UK tax to cover the US liability on the same income, but the timing differences between the UK tax year (6 April to 5 April) and the US calendar year, and differences in how each country computes gains, can leave residual US tax in individual years. The de minimis election, which lets you claim the credit without Form 1116 when all foreign income is passive and creditable taxes are no more than $300 ($600 joint), is rarely available at the income levels we see.

What about severance, garden leave and deferred bonuses?

Career breaks in financial services seldom start cleanly. Garden leave is still employment: you remain on payroll, the pay is UK employment income taxed through PAYE, and for US purposes it is earned income in the year paid. We cover the detail in our separate guide to garden leave for US citizens in London. Severance and termination payments raise their own sourcing and characterisation questions on both sides of the Atlantic. Deferred bonuses that vest during the break are the trap: the Form 2555 instructions exclude from foreign earned income any amount received after the end of the tax year following the year in which the services were performed. A deferred award from work done several years earlier that vests in your break year is therefore taxable earned income in the US but cannot be excluded, and it may need to be sourced across the years and places the work was performed. These items often mean a career-break year still has a substantial wages figure, which in turn makes the missing return more costly to leave unaddressed.

Do you need to pay estimated tax on investment income?

Possibly. When salary stops, so does UK withholding, and nothing is withheld for US purposes on UK investment income. If a US liability remains after the foreign tax credit, the IRS expects it to be paid during the year through quarterly estimated payments on Form 1040-ES (https://www.irs.gov/forms-pubs/about-form-1040-es), and underpayment can attract an addition to tax. Publication 54 notes that citizens abroad receive an automatic two-month extension to file, but interest on unpaid tax still runs from the original due date. In practice, most career-break clients we see owe little or nothing after credits, but a large gain or a vested bonus can change that.

What if you did consulting work during the break?

Many senior professionals take on a board seat, a short consulting project or an interim mandate during a break. Net self-employment earnings of $400 or more create a US filing requirement on their own, per Publication 501. That income is earned income, so the foreign earned income exclusion may apply to it, and US self-employment tax must be considered. The US-UK totalisation agreement (https://www.ssa.gov/international/Agreement_Pages/uk.html) generally assigns social security coverage to one country, and for a self-employed person living in the UK that is normally the UK, but you need the correct coverage certificate to rely on it. In the UK, consulting income above the trading allowance needs to go on a Self Assessment return.

Does UK tax residence continue during a career break in London?

Almost always, yes. If you stay in London during your break, you will remain UK resident under the Statutory Residence Test, which is described in HMRC's guidance RDR3 (https://www.gov.uk/government/publications/rdr3-statutory-residence-test-srt). Residence depends on days spent in the UK, your ties and your home, not on whether you are working. A UK resident is taxed on worldwide income and gains. Only those who leave for an extended period abroad, for example a year of travel, need to look at whether split-year treatment or non-residence could apply, and that is a fact-heavy test we would always run properly rather than assume.

Do you need a UK Self Assessment return for investment income?

Often, yes. While you were employed, PAYE handled most of your UK tax and you may never have filed a Self Assessment return. Once salary stops, investment income becomes your main income and much of it is paid gross. GOV.UK (https://www.gov.uk/tax-on-dividends) says you must tell HMRC if your dividends exceed your unused Personal Allowance plus the £500 dividend allowance. Savings interest is covered by the Personal Allowance of £12,570, the starting rate for savings of up to £5,000 where other income is below £17,570, and the Personal Savings Allowance of £1,000 for basic rate, £500 for higher rate and nothing for additional rate taxpayers, as set out at https://www.gov.uk/apply-tax-free-interest-on-savings/how-much-is-tax-free. A wealthy client living on a portfolio will usually exceed these allowances comfortably.

Capital gains on selling investments to fund the break are reported through Self Assessment as well. If you have not filed before, you register for Self Assessment through https://www.gov.uk/register-for-self-assessment. A career break can also lower your total income enough to change which UK allowances you receive, because the Personal Allowance is withdrawn at higher income levels and the savings allowance depends on your rate band, so the UK computation for the break year can look quite different from your working years.

One UK point has a direct US consequence. UK-domiciled collective funds, whether held inside or outside an ISA, are commonly treated as passive foreign investment companies for US purposes, which can bring Form 8621 and unfavourable US treatment of gains. ISAs are tax-free in the UK but carry no protection for US purposes. A career break funded by selling fund holdings can therefore generate US reporting that the client has never had to deal with before.

Worked scenario: missed US tax returns after an 18-month break

Illustration only. All figures below are assumed for the example, and an exchange rate of $1.30 to £1 is assumed throughout.

Daniel is a US citizen, single, who has lived in London for nine years. He was a managing director at a London investment bank until March 2024, served three months of garden leave, then took a career break until he joined a new firm in September 2025. He filed US returns, claiming the foreign earned income exclusion and a foreign tax credit on the excess, every year up to and including 2023. He did not file for 2024 or 2025 because, in his words, he had no salary for most of that time. He did keep filing UK Self Assessment returns.

2024: salary and garden leave pay of £95,000 (about $123,500), plus a deferred bonus tranche of £60,000 (about $78,000) from work performed in 2020 that vested in June.
2024 investment income: UK interest of £21,000 (about $27,300) and dividends of £14,000 (about $18,200).
2025: no salary until September, then £70,000 (about $91,000) of new salary; interest of £18,000 (about $23,400) and a gain of £40,000 (about $52,000) on selling UK funds to pay living costs.
Accounts: combined UK balances of roughly £1.4 million throughout, so the FBAR and Form 8938 abroad thresholds were exceeded in both years.

The analysis: both years were well above the filing threshold. The deferred bonus could not be excluded, because it was received long after the year following the year the work was done, so it was taxable earned income relying on the foreign tax credit for the UK tax paid on it. The interest, dividends and fund gain were passive category income, and Daniel's large general category carryover from his banking years could not touch them. His UK funds turned out to be passive foreign investment companies, so the 2025 gain needed Form 8621 analysis. Because the UK charged tax on the interest at higher and additional rates, the passive category credit covered most of the US tax on that income, leaving a modest residual liability.

Daniel was outside the United States for well over 330 full days in each of the past three years and had no US abode, so he met the non-residency condition for the Streamlined Foreign Offshore Procedures. His failures were non-wilful. The route he chose is covered in the catch-up section below.

How do you catch up on missed US tax returns when you return to work?

Returning to an employer often triggers the review, because onboarding or a new payroll provider asks for your US filing position. There are two main routes, and the right one depends on the size of the gap and whether every year is otherwise compliant.

Late filing with a reasonable cause statement. Where only one or two years are missing, the FBARs can be filed late through the BSA E-Filing System with an explanation for the late filing, and the missing Forms 1040 filed with all information returns. The failure-to-file penalty is calculated by reference to unpaid tax, as the IRS explains at https://www.irs.gov/payments/failure-to-file-penalty, so where the foreign tax credit reduces the liability to nil, that penalty may be small or nil. The information return penalties on forms such as 8938 and 8621 are the larger exposure, and they are not tied to tax due.

The Streamlined Foreign Offshore Procedures. The IRS page at https://www.irs.gov/individuals/international-taxpayers/us-taxpayers-residing-outside-the-united-states describes the route: file delinquent or amended returns for the most recent three years with all required information returns, file the most recent six years of FBARs, pay any tax and interest, and sign Form 14653 certifying that the failures were non-wilful. Taxpayers who complete it are not subject to failure-to-file, failure-to-pay, accuracy-related, information return or FBAR penalties. The Streamlined Foreign Offshore Procedures carry no penalty; the 5% miscellaneous offshore penalty applies only to the Streamlined Domestic Offshore Procedures. Note that the IRS withdrew its separate Delinquent FBAR Submission Procedures page around 1 July 2026, so it should not be treated as a live route.

In Daniel's case, the 2023 return had omitted the PFIC reporting on funds he held then, so Streamlined Foreign Offshore was the cleaner choice: it let him amend 2023, file 2024 and 2025, and file six years of FBARs, with penalty protection across the information returns. We then structured his ongoing filings around the foreign tax credit, having confirmed that he had not revoked his exclusion election and modelled whether revoking it would be worthwhile given the five-year re-election restriction.

Career break US and UK filing checklist

Total your worldwide gross income for each calendar year of the break, including interest, dividends, gains and any consulting fees.
Compare it with the Publication 501 threshold for your filing status, remembering the $5 threshold for married filing separately.
List every foreign account and its maximum balance for each year to confirm FBAR and Form 8938 obligations.
Identify any garden leave pay, severance and deferred bonus vesting in the break years, and the years the related work was performed.
Review your Form 1116 carryovers by category; separate general category carryovers from passive category ones.
Check whether your foreign earned income exclusion election is still in force and whether revocation makes sense before returning to salary.
Check UK fund holdings, including inside ISAs, for PFIC status and Form 8621 requirements.
Confirm UK residence, register for Self Assessment if needed, and report interest, dividends and gains.
Decide on late filing with reasonable cause or the Streamlined Foreign Offshore Procedures before you file anything.

What are the common failure modes?

Assuming the foreign earned income exclusion covers interest and dividends. It never does.
Treating a large general category carryover as protection for passive income in the break year.
Forgetting the FBAR because there was no income, when the account balances alone required it.
Filing only the most recent year and hoping the earlier gap goes unnoticed, which leaves information return exposure open.
Claiming a foreign tax credit on excluded income, which revokes the exclusion election and triggers the five-year restriction.
Ignoring PFIC reporting on UK funds sold to finance the break.
Filing piecemeal late returns first and then discovering Streamlined eligibility, when a coordinated submission would have been cleaner.

A career break is a deliberate choice; the US filing gap that follows it rarely is. If your break years are missing from your IRS record, the fix is usually straightforward once the income, accounts and elections are mapped properly across both tax systems. Our team prepares the US returns, FBARs, Form 8938, Form 8621 and UK Self Assessment returns together, so the two sides reconcile and the catch-up is filed once, correctly.
