The US-UK tax treaty (Article 12) gives UK residents 0% withholding on royalties — Amazon KDP, YouTube AdSense, software licensing, patents, and all other royalty income. Interest is also 0%. Dividends are 15% (portfolio) or 5% (corporate). Without an ITIN and Form W-8BEN, the IRS takes 30% by default. Get your ITIN for $99 through an IRS CAA — 7–11 weeks, no passport mailing.

US-UK Tax Treaty — Full Withholding Rate Table

The US-UK income tax treaty was signed on 24 July 2001 and is one of the most comprehensive tax treaties the United States has ever negotiated. It is the only major treaty that reduces royalty withholding all the way to zero.

Income Type US Default Rate UK Treaty Rate Saving on £20,000/year
Royalties — KDP, YouTube, software, patents, copyright 30% 0% Save £6,000/year
Interest — US savings accounts, bonds 30% 0% Save £6,000/year
Dividends — portfolio investors (under 10% shareholding) 30% 15% Save £3,000/year
Dividends — companies holding ≥10% US voting stock 30% 5% Save £5,000/year
Business profits — Amazon FBA, no UK physical presence Withholding risk 0% Full exemption
FIRPTA — US property sale 15% at closing File 1040-NR to recover overpaid Recover thousands
ℹ️ Note on National Insurance Number vs ITIN Some platforms (Amazon KDP, Upwork) now accept a UK National Insurance number as your "foreign tax identification number" on Form W-8BEN. However, if you need to file Form 1040-NR (to recover over-withheld tax), deal with FIRPTA, or own a US LLC, you specifically need a US ITIN. When in doubt, get the ITIN — it works on every platform, every time.

Amazon KDP — 0% Withholding for UK Authors

The United Kingdom is Amazon KDP's second-largest market after the United States. Thousands of British self-published authors earn royalties from Amazon.com — and every one of them should be paying 0% IRS withholding, not 30%.

How Amazon KDP Handles UK Authors

Amazon requires all KDP authors to complete a US tax identity interview. You will be asked to submit Form W-8BEN confirming your UK residency and tax treaty claim. Once accepted:

💰 KDP Royalties — Before vs After ITIN

UK author earns $5,000/year in Amazon.com royalties — without ITIN Loses $1,500 to IRS (30%)
Same author with ITIN + W-8BEN treaty claim Keeps 100% — 0% withheld
UK author earns $30,000/year — without ITIN Loses $9,000/year to IRS
Same author with ITIN + W-8BEN Saves $9,000/year — every year

What if Amazon Already Withheld 30%?

If Amazon has already withheld tax from your royalties, you can recover it. File Form 1040-NR (US Non-Resident Alien Tax Return) with the IRS, which requires your ITIN. The IRS will refund the over-withheld amount, typically within 6 months of filing. ITIN Plus can get you the ITIN — you will then need a US tax professional to file the 1040-NR.

British YouTubers — 0% IRS Withholding on US AdSense

Google classifies AdSense earnings from US viewers as royalties under US tax law. Without a valid W-8BEN, Google withholds 30% from all US-source AdSense revenue. British YouTubers are entitled to 0% withholding under Article 12 of the US-UK treaty.

Steps to Set Up W-8BEN on Google AdSense

  1. Go to AdSense → Payments → Manage payment profile → US tax info
  2. Click Manage → select W-8BEN (individual)
  3. Enter your ITIN (or UK National Insurance number as foreign TIN)
  4. Under Treaty benefits: select United Kingdom → Article 12 → 0% rate on royalties
  5. Sign and submit — Google reviews within 1–5 business days
  6. Once approved, all future US AdSense payments carry 0% withholding
💡 Already had tax withheld by Google? Check your AdSense payment history for any "US withholding" deductions. If Google withheld 30% before your W-8BEN was on file, you can recover it by filing Form 1040-NR. You need an ITIN to do this. Keep all your 1042-S forms from Google — they are your evidence for the refund claim.

UK Investors Selling US Property — FIRPTA & Your ITIN

The UK is consistently one of the top 5 foreign buyers of US real estate. When a UK resident sells US property, the IRS requires the buyer's solicitor to withhold 15% of the gross sale price under FIRPTA (Foreign Investment in Real Property Tax Act) — regardless of whether you made a profit.

Example: Selling a Florida Condo

A British investor sells a Miami condo for $500,000. FIRPTA withholding = $75,000 (15%). Their actual US capital gains tax liability after allowable deductions might be only $30,000. The difference — $45,000 — is refunded by the IRS after filing Form 1040-NR. That filing requires an ITIN.

FIRPTA Withholding Certificate (Form 8288-B)

If you apply for a FIRPTA withholding certificate before closing, you can reduce the amount withheld at the time of sale to match your actual estimated tax liability. This avoids tying up $75,000 in an IRS refund queue. The certificate application (Form 8288-B) requires your ITIN and must be submitted well before the closing date.

Selling US Property? You Need an ITIN.

FIRPTA withholding is 15% of the sale price. Recover the overpayment with Form 1040-NR — which requires a US ITIN. Apply now before your closing date.

Primary IRS & Treaty Sources

Frequently Asked Questions — ITIN for UK Residents

Do UK residents need a US ITIN?
Yes — if you earn US-source income from royalties (Amazon KDP, YouTube, Merch), own US property, invest in US stocks, sell on Amazon, or own a US LLC. An ITIN allows you to claim the US-UK treaty's 0% rate on royalties and 0% on interest via Form W-8BEN.
What is the US-UK tax treaty rate on royalties?
0%. Under Article 12 of the US-UK income tax treaty, royalties paid to UK residents carry zero IRS withholding. This covers Amazon KDP book royalties, YouTube AdSense from US viewers, Merch by Amazon royalties, software licensing, patents, and other intellectual property income from US sources. This is the most generous royalty rate in any US tax treaty.
Can I use my National Insurance number instead of an ITIN on W-8BEN?
Sometimes. Amazon KDP and some other platforms now accept a UK National Insurance number as the foreign TIN on Form W-8BEN. However, an ITIN is required to file Form 1040-NR (to recover over-withheld tax), for FIRPTA compliance, for US LLC Form 5472 filings, and on platforms that specifically require a US tax ID. If you have any of these needs, get the ITIN.
How long does it take to get a US ITIN from the UK?
7–11 weeks. Applying through an IRS Certified Acceptance Agent like ITIN Plus is the fastest route — your application goes directly to the IRS and you never queue at a US Embassy or post your original passport internationally.
Do British YouTubers need a US ITIN?
Yes. Submit Form W-8BEN with your ITIN (or National Insurance number) to Google AdSense. Claim the UK treaty under Article 12 for 0% withholding on royalties. Without a valid W-8BEN, Google withholds 30% from all US-source AdSense revenue.
What is FIRPTA and why do UK property investors need an ITIN?
FIRPTA (Foreign Investment in Real Property Tax Act) requires the buyer to withhold 15% of the gross sale price when a foreign person sells US real estate. UK sellers need an ITIN to file Form 1040-NR and recover any over-withheld FIRPTA amounts. They can also apply for a FIRPTA withholding certificate (Form 8288-B) before closing to reduce the amount withheld at the time of sale.
How much does an ITIN cost for UK residents?
ITIN Plus charges $99 — the lowest available price for a full IRS Certified Acceptance Agent service. This includes CAA certification, Form W-7 preparation, and IRS submission. No passport mailing. No hidden fees. Competitors and UK accountants charge £200–£500+.
Can UK Amazon FBA sellers get an ITIN?
Yes. UK Amazon FBA sellers need to complete Amazon's tax identity interview (Form W-8BEN). Business profits from selling on Amazon with no US office or employees are generally 0% under the treaty's business profits article. An ITIN makes this documentation clean and permanent.
