Royalties from both sides of the Atlantic: what authors actually owe, and where

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

Your novel sells in America, earns lending payments in Britain and picks up a translation deal in Germany. The royalty income arrives from four directions, and each payer applies its own rules before a penny reaches you. Getting the paperwork right at the start decides how much of it you keep.

Most of the losses we see are avoidable. So this guide covers what an American payer withholds, how the treaty stops it, what Britain taxes, and how the averaging rules help writers with uneven years.

Key takeaways

• American payers withhold 30% from royalties paid abroad unless a W-8BEN claims treaty relief.
• The US-UK treaty generally taxes royalties only in the country where the author lives.
• A British resident author reports all royalty income on Self Assessment, wherever it comes from.
• Professional writers usually count royalties as trading income, which brings Class 4 National Insurance.
• Averaging lets creators smooth a big year against quieter ones.
• Americans in Britain report the same royalties to the IRS as well, with credit for British tax.
• Agent commission, research and equipment come off royalty income before tax in both countries.

What is royalty income for tax purposes?

It is payment for the use of a right you own, such as copyright in a book, a song or a photograph. Advances, sales royalties, subsidiary rights and licence fees all fall inside it. For a working author, most of it forms part of the trade of writing rather than standing apart as investment income.

That classification matters on both sides. Trading income brings National Insurance in Britain and self-employment tax in America. Royalties from rights you inherited or bought usually sit outside the trade instead.

Why do American publishers withhold 30%?

Because US law requires tax at source on royalties paid to non-American recipients unless a treaty reduces it. The payer cannot apply the treaty rate on trust. It needs a signed W-8BEN confirming your residence and claiming the relevant treaty article.

Without that form, 30% leaves the payment before it reaches you. Recovering it later means filing an American return, which takes months and rarely feels worth the effort for modest sums.

With the form in place, the rate usually falls to nil. According to IRS guidance on withholding for foreign persons, the payer keeps the form on file and applies the reduced rate to every payment it covers.

How to complete a W-8BEN properly

The form is short, but small errors void it. The payer needs your name, address, country of residence and a taxpayer number, plus the treaty claim in Part II. Many platforms walk you through it as an online interview.

1. Confirm you are resident in Britain for the year the payments will cover.
2. Enter your British tax reference as the foreign taxpayer number.
3. Claim the royalty article of the US-UK treaty in Part II.
4. State the treaty rate, usually nil, and the type of income claimed.
5. Sign and date the form, then keep a copy with your tax records.
6. Diarise renewal, because the form generally lasts about three calendar years.
7. Tell each payer promptly if you move, because the treaty claim follows your residence.

What Britain taxes

A British resident pays tax on worldwide royalty income through Self Assessment. For a professional author, royalties form part of trading profit, taxed at income tax rates with Class 4 National Insurance on top. Allowable costs such as agent fees, research travel and equipment come off first.

Public Lending Right payments count as income too. So do distributions from collecting societies such as ALCS, which pass on money for secondary uses like photocopying. Both belong on the return even though they arrive as small, irregular sums.

What costs can authors deduct?

Costs incurred wholly and exclusively for the writing trade. Agent commission, research travel, books, software, a share of home running costs and professional memberships usually qualify. Costs that mix private and business use need a fair split, and your records should show how you reached it.

Agent commission deserves a note. Many agents deduct it before paying you, so the royalty income on your statement is already net. Report the gross figure and claim the commission, or report net consistently. Mixing the two double-counts the cost.

The American side has its own list. Schedule C allows similar costs for an American author, though the rules on home offices and travel differ in the detail.

When does writing become a trade?

When you write with a view to profit, regularly and in a businesslike way. A first novel sold after years of weekend work may still count as trading from the start. Occasional payments to someone who does not write for a living usually fall outside the trade instead.

The difference affects National Insurance and losses. Trading losses in an early year can sometimes reduce other income. Miscellaneous income losses are far more restricted.

How does averaging help writers?

It spreads a spike across two or five years. Britain lets people whose profits come mainly from creative work average them, so a large advance does not push one year into the top rates. The claim is made through Self Assessment and can be reversed if circumstances change.

Averaging suits authors with lumpy income. A £90,000 year followed by two £15,000 years produces far less tax once smoothed. Our clients who write for a living usually benefit from at least looking at it.

America has no direct equivalent for authors. An American writer in Britain may therefore show smooth profits here and a spike on the American return, with the credit rules evening things out imperfectly.

What about Americans living in Britain?

They report the same royalty income twice. Britain taxes it as the country of residence. America taxes it as the country of citizenship, then gives credit for British tax paid on the same income.

Self-employment tax is the trap. A working author's royalties count as self-employment income in America, and the 15.3% charge applies unless a certificate of coverage shows British National Insurance covers you instead.

Our guide to the self-employed American in Britain covers the wider return, including how profits and costs line up across the two systems.

A worked example

The figures below are illustrative. Take an example: a British author living in Norwich earns $40,000 from an American publisher, £18,000 from a British one, and £1,200 from lending and collecting society payments in 2025-26.

Without a W-8BEN, the American publisher withholds $12,000. With the form in place, it withholds nothing, and the full $40,000 arrives. That single form is worth more than every other step in this guide combined.

In Britain, all three streams go on the Self Assessment return as trading income. After agent fees and costs, the author pays income tax and Class 4 on the combined profit. Had the $12,000 been withheld, reclaiming it would have meant an American return and a long wait.

Do audiobook and film rights work the same way?

Broadly, yes. Audiobook deals, film options and merchandise licences all count as royalty income for tax purposes. The payer may differ, and so may the withholding, but the Self Assessment treatment follows the same pattern as book royalties.

Film options need care on timing. An option fee can arrive years before any film, and it stays taxable when received even if the film never gets made.

Check the contract for who holds the rights afterwards. An outright sale of rights can be a capital disposal rather than income, which changes the tax completely.

Other countries and translation rights

Foreign publishers often deduct their own tax too. Treaties with most countries reduce it, though each has its own forms and its own timing. Where tax still comes off, Britain usually gives credit against the British tax on the same royalty income.

Keep every remittance advice showing tax deducted. Without it, the credit is hard to claim, and the money is effectively lost.

Translation deals often run through your agent or your original publisher. Ask who deducted what, and when, because the paperwork can sit two steps away from you.

Currency and timing

Royalties paid in dollars must be converted into pounds for the British return. Use the rate on the date of receipt, or a consistent average method, and apply it every year. Mixing methods between years makes the figures hard to defend.

Royalty statements often arrive months after the sales they cover. Tax follows the date you receive the money, not the date of the sales, so statements and bank credits need matching.

Keep the dollar amount alongside the sterling figure. If you ever need to reclaim American tax, the IRS will want the original currency.

What records should authors keep?

Every royalty statement, every remittance advice, and every W-8BEN you have signed. Keep bank statements showing each payment arriving, and a simple spreadsheet matching the two. Add receipts for costs, plus notes explaining any split between private and business use.

Keep them for at least six years. Royalty income can run for decades, and a question about one payment can reach back further than you expect.

Mistakes and penalties we see with royalties

• Never filing a W-8BEN, then losing 30% of every American payment at source.
• Letting the form lapse after three years without noticing the withholding restart.
• Leaving Public Lending Right and collecting society income off the return.
• Treating an advance as a loan rather than income in the year it arrives.
• Missing averaging in a year with an unusually large advance.
• Paying American self-employment tax on royalties without checking social security coverage.

Late or missing Self Assessment returns bring automatic penalties in Britain, even where no tax is due. And withholding lost at source for lack of a form is rarely worth the cost of recovering.

Most of these slips cost little to prevent. A diary note for each form and a folder for each year covers nearly all of them.

What if you work through a company?

Some authors assign their rights to a limited company. The company then receives the royalty income, pays corporation tax and distributes profit as salary or dividends. That can help at higher incomes, but it adds cost and paperwork.

The company needs its own W-8BEN-E rather than a personal W-8BEN. For an American author, the company also raises reporting questions on the American side, so take advice before assigning any rights.
