Britain does not tax your winnings. America taxes every penny

Figures relate to tax year 2025-26 (UK) · 2025 (US)

You had a good year on the horses, or the poker went your way, or a lottery line finally came in. Nobody deducted anything and nobody sent you a form.

Britain does not tax the punter, and that is genuinely the rule rather than an oversight. America takes the opposite view entirely. Gambling winnings are ordinary income to a US citizen, wherever in the world the bet was placed.

Key takeaways

• Britain taxes the operator rather than the person placing the bet.
• America taxes the gambling winnings of its citizens as ordinary income.
• No British tax paid means no foreign tax credit to offset the charge.
• Losses can be deducted, but only against winnings and only if you itemise.
• You report the gross winnings, not the net figure you walked away with.
• Records matter more here than in almost any other area.

What is the UK position on gambling winnings?

Britain taxes the operator, through duties charged on the business rather than the customer. According to HMRC guidance, a punter pays no income tax or capital gains tax on a win, and cannot claim relief for a loss either. The system deliberately leaves the individual out of it.

That applies whether you bet on a horse, a hand or a lottery line.

So a British-only taxpayer never thinks about this at all.

How does America treat gambling winnings?

As ordinary income in the year you receive them, taxed at your marginal rate alongside your salary. Per IRS guidance, the rule covers lotteries, raffles, horse races, casinos and the cash value of non-cash prizes. Nothing about the British treatment changes that answer.

There is no special rate and no holding period to help you.

So a large win in a year with a good salary can land in the top bracket.

Why is there no credit to claim?

Because a foreign tax credit relieves double taxation, and only one country is taxing you here. Britain collected nothing from you, so there is nothing to credit against the American bill and the charge stands alone.

It is the same trap that catches tax-free British reliefs generally.

Our guide to the foreign tax credit explains why an exempt gain is the worst kind.

A worked example

The figures below are illustrative and use round numbers to show the mechanics.

Ben, an American living in Leeds, wins £40,000 on an accumulator in March. Across the same year he lost about £9,000 on other bets.

Britain taxes none of it and gives no relief for the losses either. His American return shows roughly $50,000 of ordinary income from the win.

He can deduct his losses against that income, but only if he itemises and only up to the winnings. If the standard deduction suits him better overall, the losses give him nothing at all.

Can you deduct your losses?

Only against winnings, and only if you itemise your deductions. You cannot use gambling losses to reduce your salary, and you cannot carry an excess loss forward to a later year. The deduction stops at the amount you won.

Somebody taking the standard deduction gets no benefit from losses at all.

Track them as you go. Reconstructing a year of losses in April rarely produces a defensible figure.

That single restriction makes the American position considerably harsher than it first appears.

The two systems compared

Do you report gross or net?

Gross, and this catches people badly. Gambling winnings go into income at their full amount, and the losses come off separately as a deduction rather than netting against the wins. A break-even year can therefore still raise your reported income.

Higher reported income can taper other reliefs and credits.

So the headline figure matters even when the bottom line is zero.

What records should you keep?

A log of dates, venues or platforms, stakes and gambling winnings or losses, supported by account statements. Online operators usually provide an annual summary on request, and that document does most of the work for you.

Cash betting is much harder to evidence after the fact.

Without records, the losses are the part you lose first.

Does it matter if you are a professional?

It changes the American analysis considerably. Somebody genuinely in the trade of gambling reports on a business basis, which allows expenses and changes how losses behave. The threshold for that treatment is high and the facts have to support it.

Britain still generally treats even a professional punter as untaxed.

Employment alongside the betting usually weighs against business treatment.

So the gap between the two systems widens rather than narrowing.

What about spread betting?

Britain treats it as gambling and taxes the punter on nothing. America looks at the substance, and a financial spread bet can resemble a trading position rather than a wager, which pulls it towards the ordinary rules for gains.

The classification drives the rate and the loss treatment.

Contracts for difference sit closer still to ordinary trading on the American side.

Take advice before assuming it follows the same path as a football bet.

Does a non-cash prize count?

Yes, at its cash value. A car, a holiday or a hospitality package won in a draw all count as income at what they were worth when you received them, which sometimes exceeds what you would have paid for them.

Britain still asks nothing, so there is no British valuation to lean on.

Selling the prize afterwards is a separate transaction with its own gain or loss.

Keep the operator's own stated value where they publish one.

What about prize draws and raffles?

They sit in the same category. A charity raffle, a workplace draw and a supermarket competition all produce reportable income for an American winner, however informal the event felt at the time.

Small amounts still count, even though nobody issues paperwork.

Most people never think of a raffle as gambling at all.

Does it affect your state position?

Only where a state still claims you as a resident. Some states tax this income and give no relief for losses at all, which makes the position worse than the federal one.

Our guide to US state tax for expats covers breaking the connection.

Check it before assuming the federal answer is the whole story.

How to report it

1. Total your gross winnings for the calendar year, not the British tax year.
2. Convert each amount to dollars at the rate on the day you received it.
3. Total your losses separately, with evidence for each.
4. Report the gross winnings as other income on your return.
5. Compare itemising against the standard deduction before claiming losses.
6. Keep the operator statements with your tax papers.
7. Check whether the win pushes you into estimated payment territory.

What if you win in America?

Then the position reverses for a British resident. American casinos and lotteries withhold tax from large payouts to non-residents at source, and a British winner may be able to reclaim some of it under the treaty.

That reclaim needs an American tax reference number and a return.

The reclaim window runs for several years, so an old win may still be recoverable.

Plenty of British holidaymakers never claim it back at all.

Does a big win affect your payments on account?

In America it can, because ordinary income arriving without withholding often creates an underpayment charge. Britain asks nothing, so your self assessment position is unchanged, but the American side may need a payment during the year.

Our guide to estimated tax payments from the UK covers the timing.

A single quarterly payment usually removes the charge entirely.

Deal with it in the quarter you win, not the following April.

What about a lottery syndicate?

Each member reports their own share of the gambling winnings, so the American in a workplace syndicate reports their slice rather than the whole prize. Keep the syndicate agreement and evidence of the split, because without it the organiser can appear to have received everything.

Sharing a prize after the event can look like a gift instead.

Name every member in writing before the draw. A list written afterwards carries far less weight.

That distinction is worth getting right before the money moves.

Does an online account abroad need reporting?

It can. A betting or exchange account holding a balance counts as a foreign financial account for reporting purposes, and it feeds into the annual threshold alongside your ordinary bank and savings accounts rather than sitting separately.

Peak balance during the year is the test, not the closing one.

Our guide to FBAR deadlines and penalties covers the mechanics.

What if the win arrives in instalments?

You report each payment in the year you receive it. Annuity-style lottery prizes therefore spread across several returns rather than landing in one, which can keep you out of the top bracket.

A lump sum option brings the whole amount into a single year.

Where you have a choice, the American position is worth modelling first.

Does the treaty help at all here?

Not for an American living in Britain. The saving clause lets America tax its own citizens as though the treaty were absent, and no exception covers gambling income for a citizen.

It does help a British resident who wins in America, by reducing or removing the withholding.

So the treaty works in one direction only on this.

Is a betting exchange treated differently?

Not in Britain, where laying and backing both sit outside the tax net. America looks at the activity rather than the platform, so regular trading on an exchange can start to look like a business.

Volume, consistency and intent all feed that judgement.

Somebody doing it full time should take advice rather than assume.

Mistakes and penalties we see with gambling winnings

The first is assuming gambling winnings that are tax free in Britain stay invisible in America. It is the single most common misunderstanding here.

The second is netting losses against wins before reporting. The two go in separate places.

The third is claiming losses while taking the standard deduction. That claim simply does not work.

The fourth is keeping no records. Winnings are easy to evidence and losses are not.

How US UK Tax Accountants helps

We work out the dollar figures from your operator statements, test whether itemising beats the standard deduction once the losses are in, and check whether a payment during the year keeps a charge away. Then we prepare the return.

Where an American payout was withheld at source, we handle the reclaim. Our US federal return service covers the filing.

If you have had a good year, get in touch before the return is due. The planning that helps here happens while the year is still open.
