Is UK Statutory Maternity Pay taxable on a US tax return?

Yes. Statutory Maternity Pay is paid by your employer through PAYE and is treated as wages, so it is reported as foreign employment income on your US return and converted to dollars. Any UK income tax withheld on it is creditable in the United States through the foreign tax credit, which usually eliminates any US tax on the pay.

Is UK Maternity Allowance taxable in the US even though it is tax-free in the UK?

Generally yes. The United Kingdom does not tax Maternity Allowance, but the United States taxes its citizens on worldwide income and has no carve-out for a foreign maternity benefit, so it is normally includible on the US return. Because it bore no UK tax there is no foreign tax credit on it, though for a typical maternity year the standard deduction usually keeps the overall US tax at nil.

Can I use the foreign earned income exclusion for maternity pay?

SMP, as employer-paid wages, may qualify as foreign earned income that Form 2555 can exclude, but Maternity Allowance, as a state benefit, generally does not. Even for SMP the exclusion is usually the wrong choice for a new parent, because electing it removes the earned income that the refundable child tax credit is calculated from. The foreign tax credit is normally the better tool.

Can a US citizen in the UK get a refund for a new baby while owing no US tax?

Often yes. The additional child tax credit is refundable, up to 1,700 dollars per child for 2025, and can be paid even when your US tax is nil. The child needs a Social Security number by the return due date, and the refund is computed from your earned income, so you must file and should use the foreign tax credit rather than the exclusion to keep that earned income on the return.

Does my child need a Social Security number to claim the credit from abroad?

Yes. The child tax credit and its refundable portion require a qualifying child with a Social Security number issued by the due date of the return, including extensions. A baby born in the UK to a US-citizen parent is generally a US citizen; you register the birth through a Consular Report of Birth Abroad and apply for the number, which is worth starting early because it takes time.

How do I catch up on missed US tax returns after a maternity year?

The usual route for a non-willful taxpayer abroad is the Streamlined Foreign Offshore Procedures, which require the three most recent years of returns, six years of FBARs and a Form 14653 non-willful certification. You reconstruct each year from your P60s, DWP award notices, bank statements and GOV.UK Personal Tax Account. If your UK accounts exceeded 10,000 dollars in aggregate in any year, a FinCEN Form 114 is also due for that year.

Missed US Tax Returns: UK Maternity Pay Explained

Having a baby in the United Kingdom and falling behind on US filing tend to happen at the same time, for the plainest of reasons: a new parent has more pressing demands than a tax return owed to a country she no longer lives in. Missed US tax returns feel like a problem for another day, right up to the moment a bank form, a mortgage application or a letter from the IRS turns another day into today. For a US citizen who spent a maternity year on UK Statutory Maternity Pay or Maternity Allowance, the reassuring part is that the numbers are usually far gentler than the dread suggests. The awkward part is that those two kinds of maternity income are not the same thing, and the United States does not treat them the same way.

This article is written for that person: an American mother in Britain, a year or several behind, whose income for the relevant years was modest and largely a maternity payment. It explains the difference between Statutory Maternity Pay and Maternity Allowance, how each is likely to land on a US return, why the foreign earned income exclusion is often the wrong tool and the foreign tax credit the right one, and how a new child can turn a catch-up filing into a refund. The treatment below is general and fact-specific; the aim is to show how the pieces fit, not to compute anyone's return.

Why do missed US tax returns matter when the only UK income was maternity pay?

Because US citizens are taxed on their worldwide income wherever they live, and the duty to file does not switch off when you leave the country or when your income is low and foreign. The filing thresholds are low, and for a married person filing separately, a common default for an American married to a non-American, the threshold is only a few thousand dollars of gross income. A maternity year rarely falls below it. So the return is almost always required, even when, as is usual here, the final tax owed is nil.

The reason missed US tax returns deserve attention rather than panic is that an unfiled year never closes. The IRS assessment clock does not start until a return is filed, so a return due years ago is just as open today as last year's. That cuts a helpful way for a low-income maternity year: there is no tax hiding in it, so filing it correctly usually costs nothing and can unlock money instead. The exposure that does exist tends to sit in the foreign account reports, not the income tax itself.

What is the difference between Statutory Maternity Pay and Maternity Allowance?

They answer the same need, income while you are off work with a new baby, but they come from different places, and that difference drives everything on the US side. Statutory Maternity Pay, or SMP, is paid by your employer through the normal payroll. Maternity Allowance, or MA, is paid by the government through the Department for Work and Pensions to people who do not qualify for SMP, typically the self-employed, the recently employed, or those whose earnings were below the SMP threshold. GOV.UK sets out the two schemes separately.

Statutory Maternity Pay (SMP): paid by the employer via PAYE for up to 39 weeks, broadly 90 per cent of average weekly earnings for the first six weeks, then the lower of a flat statutory weekly rate or 90 per cent of earnings for up to a further 33 weeks.
Maternity Allowance (MA): paid by the government rather than an employer, for up to 39 weeks at the lower of a flat statutory weekly rate or 90 per cent of average weekly earnings, aimed at those who cannot get SMP.
UK tax: SMP is treated as earnings and is subject to UK income tax and National Insurance through payroll; Maternity Allowance is a state benefit and is not taxable in the UK.
The US question: SMP looks like wages and Maternity Allowance looks like a government benefit, and those two descriptions lead to different answers on a Form 1040.

How does a US return treat Statutory Maternity Pay?

As wages, in substance. SMP is paid by your employer, runs through PAYE alongside any ordinary salary, and appears on your UK payroll records as part of your pay. On the US return it is reported as foreign employment income, the same line your salary would use, and converted from pounds to dollars at a reasonable exchange rate for the year. Nothing about SMP being a statutory entitlement changes its character as pay from an employer for US purposes.

That matters for two reasons. First, SMP is generally foreign earned income, which keeps the full menu of reliefs available: both the exclusion and the foreign tax credit are on the table. Second, because SMP went through PAYE it will usually have borne some UK income tax, and that UK tax is creditable in the United States. Whether SMP counts as earned income in a given year is ultimately fact-specific, because the exclusion rests on compensation for services, but employer-paid maternity pay is conventionally treated as a continuation of wages rather than a detached benefit.

How does a US return treat UK Maternity Allowance?

Differently, and this is the nuance that trips people up. Maternity Allowance is not paid by an employer and is not compensation for work performed; it is a benefit paid by the state, and the United Kingdom does not tax it. But the United States taxes the worldwide income of its citizens, and no US provision carves out a foreign maternity benefit. The default position, therefore, is that Maternity Allowance is includible in gross income even though it was tax-free in Britain. That mismatch, tax-free in the UK but reportable in the US, is exactly what a domestic-only preparer misses.

The consequence is twofold. Because Maternity Allowance is not compensation for services, it is generally not foreign earned income, so the foreign earned income exclusion cannot reach it. And because the UK levied no tax on it, there is no UK tax to credit against any US tax it generates. In isolation that could produce a small US liability on the Maternity Allowance slice, but for a typical maternity year the standard deduction usually absorbs it, so the practical result is often still nil tax, just reached by a different route than SMP. The treatment can turn on the specific facts, so it is worth confirming rather than assuming.

Does maternity pay count as earned income for the FEIE?

This is the question that decides which tool you reach for. The foreign earned income exclusion, claimed on Form 2555, only works on foreign earned income, meaning compensation for personal services performed abroad. Statutory Maternity Pay, as employer-paid wages, may qualify. Maternity Allowance, as a pure state benefit, generally does not. So a mother whose maternity income was entirely Maternity Allowance has nothing for Form 2555 to exclude, and reaching for it out of habit achieves nothing while causing harm elsewhere.

Even where SMP would qualify, the exclusion is rarely the right choice for this profile, and the reason is the child, not the income. Electing the exclusion on Form 2555 removes the excluded pay from your earned income, and, as the next sections show, that is exactly the figure the refundable child credit is built on. Exclude the income and you can erase the very refund a new parent is entitled to. For a maternity year the foreign tax credit almost always does more work.

Why is the foreign tax credit usually the better tool here?

The foreign tax credit, claimed on Form 1116, credits the UK tax you paid against the US tax on the same income, dollar for dollar, rather than removing the income from the return. For a maternity year that has a decisive advantage: it leaves your earned income on the return, where it can support a refundable child credit, while still wiping out any US tax through the UK tax already paid on SMP. It is also the only tool that does anything for Maternity Allowance, though, since MA bore no UK tax, the credit on that slice is zero.

It preserves earned income: the credit does not strip SMP out of the return, so that pay still counts toward the refundable additional child tax credit.
It uses tax you already paid: UK income tax withheld through PAYE on SMP credits against US tax on the same pay, usually eliminating any US liability for the year.
It keeps the refund available: filing Form 2555 to claim the exclusion disallows the additional child tax credit, a point IRS Publication 54 makes explicitly; the credit route avoids that trap.
It carries forward: any UK tax not needed in a given year carries back one year and forward ten, rather than being wasted.
It needs no lock-in: the credit is claimed annually with no continuing election and no multi-year revocation penalty, unlike the exclusion.

Can a new baby in the UK produce a US refund?

Yes, and this is the part that turns catching up from a grudging exercise into a worthwhile one. A child born in the UK to a US-citizen parent is generally a US citizen, and once that child has a Social Security number, the parent can claim the child tax credit. The credit is worth up to 2,000 dollars per qualifying child, and part of it, the additional child tax credit, up to 1,700 dollars per child for 2025, is refundable, meaning it can be paid to you even when you owe no US tax. For a mother whose US tax is already nil, that refundable slice is real money.

Two conditions do the heavy lifting. The child must have a Social Security number issued by the due date of the return, which for a baby born abroad usually means registering the birth through a Consular Report of Birth Abroad and applying for the number, worth starting early because it takes time. And the refundable amount is calculated from your earned income, broadly 15 per cent of earned income above 2,500 dollars, capped at the per-child limit. This is where SMP and Maternity Allowance part company again: SMP, as earned income, builds that base; Maternity Allowance, as a benefit, does not. Had you excluded the SMP on Form 2555, there would be no earned income left to compute the refund from.

A worked example: SMP, Maternity Allowance and a refundable credit

The following uses a fictional taxpayer and rounded, illustrative figures; it is not a computation for any real person. Emily Carr is a US citizen who has lived in London for several years, is UK tax resident, and last filed a US return before her move. She and her UK-citizen partner had a daughter during the year in question, and the daughter now has a Social Security number. Emily has not filed US returns for the three years now in question. An illustrative rate of 1.27 dollars to the pound keeps one set of numbers on the page.

Take the year she was employed. Emily earned roughly £8,000 of salary before going on leave and then received about £12,000 of Statutory Maternity Pay, a total of £20,000, around 25,400 dollars, all run through PAYE with some UK income tax withheld. On the US return she reports the full amount as wages and claims the foreign tax credit for the UK tax paid, which covers the modest US tax the income would otherwise attract and leaves nil US tax. Because she did not exclude the pay, her earned income is about 25,400 dollars. The refundable additional child tax credit, computed as 15 per cent of earned income over 2,500 dollars, comfortably exceeds the per-child cap, so Emily claims the full refundable amount, up to 1,700 dollars, despite owing no US tax.

Now change one fact. Suppose Emily had not qualified for SMP and instead received Maternity Allowance, say £8,000 of earlier salary and £7,000 of Maternity Allowance. The Maternity Allowance was tax-free in the UK, but it is includible on her US return, and because it is not earned income it neither feeds the exclusion nor counts toward the refundable credit. Only the £8,000 of salary, about 10,160 dollars, builds her earned-income base, so her refundable credit is smaller, roughly 15 per cent of 7,660 dollars, or about 1,149 dollars. The Maternity Allowance bore no UK tax, so there is nothing to credit on it, though the standard deduction still keeps her overall US tax at nil. Same mother, same baby, two maternity schemes, and a measurably different refund, which is why the SMP versus MA distinction is worth getting right.

How do you reconstruct the figures and catch up through Streamlined?

The figures are more recoverable than most people fear. SMP shows up on your UK payroll records and on the P60 your employer issues after each tax year; Maternity Allowance is evidenced by the DWP award notice and your bank statements. Your Personal Tax Account on GOV.UK holds pay and tax details, and HMRC can supply records for years you no longer have paperwork for. With pay, UK tax withheld and the dates of your maternity period in hand, each year can be rebuilt and converted to dollars at a reasonable annual rate without guesswork.

For a non-willful taxpayer living abroad, the usual route back is the Streamlined Foreign Offshore Procedures. As set out on IRS.gov, they require filed or amended returns for the most recent three years for which the due date has passed, FBARs for the most recent six years, and a Form 14653 certification that the failures were non-willful. A US citizen also has to meet the non-residency test, meaning no US abode and physical presence outside the United States for at least 330 full days in one of the three years, which a mother settled in the UK generally meets easily. Qualifying submissions carry no failure-to-file, failure-to-pay, accuracy or FBAR penalties. Separately, if your UK accounts together topped 10,000 dollars at any point in a year, a FinCEN Form 114 is due.

Confirm whether your maternity income was SMP (employer, via PAYE) or Maternity Allowance (a government benefit), because the answer changes the US treatment.
Get your child a Social Security number through a Consular Report of Birth Abroad, and start early, because the refundable credit depends on it.
Choose the foreign tax credit over the foreign earned income exclusion so your SMP stays in the earned-income figure the refund is built on.
Pull your P60s, DWP award notices, bank statements and GOV.UK Personal Tax Account to reconstruct pay and UK tax for each open year.
Check whether your UK accounts exceeded 10,000 dollars in aggregate at any point in a year, which triggers an FBAR for that year.
File the three most recent years, with six years of FBARs and a non-willful certification, under the Streamlined Foreign Offshore Procedures.

For most new parents in this position, missed US tax returns turn out to be a formality with a silver lining rather than a liability. A maternity year built on Statutory Maternity Pay, filed with the foreign tax credit rather than the exclusion, usually produces no US tax and a refundable credit for the new child; a year built on Maternity Allowance is includible but still rarely taxable, and simply yields a smaller refund. The mistakes that cost money here are not about owing tax. They are about reaching for Form 2555 out of habit and excluding away the refund, or leaving the years unfiled until the IRS or a lender forces the issue. Reconstruct the figures, pick the right tool, claim the child, and the catch-up becomes something you can close off for good.
