How to Invoice International Clients as a US Freelancer

You landed a client in London, Berlin, or Singapore. Now comes the part nobody prepares you for: actually getting paid. Knowing how to invoice international clients correctly — which currency to use, how the money moves, what the IRS expects — separates the freelancers who get paid cleanly from those who chase wire transfers for weeks. None of it is complicated once you know the rules.

USD or Foreign Currency? Pick One — and Make It USD

The answer is simple: invoice in USD. Full stop. Your expenses are in USD. Your tax return is in USD. Introducing a foreign currency creates FX risk, extra bookkeeping, and an IRS headache on every payment.

Larger European or Asian companies sometimes push for local currency. Don't absorb the loss. Build a 3–5% FX buffer into your rate. Whatever currency you settle on, state it explicitly on the invoice — "All amounts in USD" — so there's no dispute when payment clears at a slightly different rate two weeks later.

Here's the IRS wrinkle: if you're paid in euros or pounds, you must convert to USD at the spot rate on the date you received payment — not the invoice date. Manual rate lookups, IRS.gov tables, extra math. Invoice in USD and you skip all of it.

How to Actually Get Paid: Wire, Wise, or PayPal

Invoicing in the right currency only matters if the money arrives. These three payment rails are not equal.

"Put your Wise account details or SWIFT code directly on the invoice. Every extra email asking 'how do I pay you?' costs you a day."

Include payment details on the invoice itself — routing number, SWIFT/BIC code, or Wise account info. Don't make the client ask. If you're unsure which fields belong, the guide on what to put on an invoice covers the full list.

For wire transfers, add a wire fee line item — "International wire fee: $35" — or build it into your rate. Don't silently absorb it. Freelancers who bill regularly will find the full billing setup covered in the guide on how to invoice as an independent contractor.

The IRS Doesn't Care Where Your Client Is

The US taxes on citizenship and residency — not on where the money originates. Every dollar from a UK agency, a German startup, or a Canadian brand is fully taxable on your Schedule C. No exceptions.

Four things that matter on the tax side:

1. No 1099 from foreign clients. Self-report all foreign income on Schedule C.
2. Currency conversion. Paid in a foreign currency? Convert to USD at the spot rate on the date received — IRS.gov publishes annual averages, or use xe.com for exact dates.
3. No US VAT obligation. US freelancers providing services to foreign B2B clients generally don't charge VAT. The client's country handles it via reverse-charge rules.
4. Foreign tax withholding. If a client withholds local taxes, you may qualify for a Foreign Tax Credit via Form 1116 — a dollar-for-dollar credit. Flag it with a CPA.

This is not tax advice. If you operate as an LLC or S-corp, your situation differs. Consult a tax professional.

What Goes on an International Invoice (Checklist)

A UX designer we'll call James spent two weeks chasing payment from a Berlin client because he forgot his SWIFT code. Professional invoice. Stalled accounts payable team. Two weeks of follow-up emails. Don't be James.

Start with your standard invoice — as detailed in the guide on what to put on an invoice — then add these international fields:

Also include clear invoice payment terms (Net 15 or Net 30 travels well internationally) and a late fee clause. International payment chains have more moving parts. Late fees create urgency without awkward follow-up emails.

Frequently Asked Questions

Should I invoice international clients in USD or their local currency?

Invoice in USD whenever possible. It protects you from exchange-rate swings and simplifies IRS reporting. If a client insists on their local currency, add a 3–5% FX buffer to your rate — don't absorb the loss silently.

Do I owe taxes on income from foreign clients?

Yes. The IRS taxes US freelancers on worldwide income regardless of where the client is located. Foreign clients won't issue a 1099, so self-report all foreign income on Schedule C. Convert any foreign currency payments to USD at the spot rate on the date received.

What's the cheapest way to receive international payments?

Wise — fees run roughly 0.5–1% at the mid-market rate. Wire transfers are reliable but cost $25–$50 per transfer. PayPal is the most expensive at 4–5% plus a poor exchange rate; reserve it for one-off invoices under $500.

What if an EU client asks for my VAT number?

You don't have one — and that's fine. Add to your invoice: "VAT not applicable — US-based service provider." EU B2B clients apply reverse-charge VAT on their end. It's not your registration to manage.

Cross-border invoicing isn't complicated once the setup is right. Lock in USD, put your payment details upfront, and keep clean records for tax season.
