How to Invoice US Clients from the UK: 2026 Guide
Transatlantic contracting between the United Kingdom and the United States represents one of the largest professional service corridors in the world. Whether you operate as a UK sole trader or through a limited company (PSC), you must handle HMRC VAT rules correctly and ensure your US client does not deduct 30% IRS withholding tax. Here is the complete playbook.
2,200,000+ Independent Professionals
Form W-8BEN (Individuals) or W-8BEN-E (Limited Companies)
Outside the Scope of UK VAT (Place of Supply of Services Rules)
How Much Money Do You Lose on a $10,000 Payment?
Traditional payment middlemen take advantage of foreign exchange spreads and international transfer fees. Here is the reality:
£20 outgoing + £12 incoming + 2.5% FX spread
Loss: $350 - $450
2.9% + 1.5% international + 2.0% currency fee (~6.4%)
Loss: $640
0% app fee + 0.35% mid-market conversion
Loss: $35
4-Step Compliance Playbook: United Kingdom to US
Follow these essential tax and banking steps to ensure legitimate payment and 0% US withholding tax:
1. Determine UK VAT Treatment ('Outside the Scope')
Under HMRC's 'Place of Supply of Services' rules for Business-to-Business (B2B) transactions (HMRC Notice 741A), the place of supply of services to a US business customer is where the customer belongs—the United States. Therefore, the supply is 'outside the scope' of UK VAT.
2. Submit Form W-8BEN or W-8BEN-E
If you operate as a sole trader, submit Form W-8BEN with your UK National Insurance Number (NINO) or Unique Taxpayer Reference (UTR) in Box 6a. If you invoice via a UK Limited Company, submit Form W-8BEN-E with your company UTR. Claim Treaty Article 7 (Business Profits) to secure 0% US withholding tax.
3. Open a Wise Business Multi-Currency USD Account
Do not ask US clients to send expensive international wires to your UK bank's IBAN. A Wise Business account provides local US ACH routing details (ABA routing and account number). Your client pays via domestic ACH with zero friction, and you convert to GBP at genuine mid-market rates.
4. Maintain Evidence of Overseas Business Customer Status
To defend your 'outside the scope' VAT treatment during an HMRC audit, you must maintain commercial evidence that your customer is a genuine US business (e.g. client corporate address, contract, or state corporate registry record).

Frequently Asked Questions: United Kingdom to US Invoicing
Do I charge UK VAT to US business clients?
No. For B2B professional services, the place of supply is deemed to be where the customer belongs (the United States). Therefore, the transaction is outside the scope of UK VAT and you should apply 0% VAT to your invoice.
What is the difference between Form W-8BEN and W-8BEN-E?
Form W-8BEN is for individuals (sole traders / freelancers). Form W-8BEN-E is for corporate entities (UK Limited Companies). Both certify non-US status and claim treaty relief under the US-UK Double Tax Treaty.
Should I invoice in USD or GBP?
Invoicing in USD ($) is standard practice when working with American companies and eliminates billing hesitation. Use a multi-currency account (like Wise Business) so you receive USD with no forced conversion fees and exchange into GBP when currency rates are favorable.
Does export revenue count towards the UK VAT registration threshold?
Yes. Even though export services are zero-rated / outside the scope of UK VAT, supplies that would be taxable if made in the UK generally count towards your £90,000 VAT registration threshold. Check with your accountant if your turnover is approaching the threshold.
