Getting Paid by International Clients: Currency, Tax Forms and Contract Terms
Cross-border work adds currency risk, withholding paperwork and slower payments. Here is what the IRS says about Form W-8BEN, how invoice currency shifts your income, and the contract terms that prevent surprises.
International clients are one of the great advantages of freelancing. They can also produce some of its least pleasant surprises: a payment that arrives short because of a fee no one mentioned, a request for a tax form you have never heard of, or an invoice worth less than you expected because the exchange rate moved.
Most of these are avoidable with a few decisions made before you send the first invoice.
Key takeaways
- The currency you invoice in decides who carries exchange-rate risk. In our example, a 5% currency move changes a $10,000 invoice by $500 either way.
- The IRS says a foreign individual gives Form W-8BEN to a US payer to document foreign status and, where relevant, claim a treaty reduction or exemption from withholding. Without it, a payer may have to withhold at 30% or at the backup withholding rate.
- A Form W-8BEN generally stays valid from the date it is signed until the end of the third following calendar year, unless your circumstances change.
- US-based freelancers working for foreign clients still report that income. Foreign clients often do not send US tax forms, so keep your own records.
- Put currency, who pays transfer fees, the payment date and tax responsibility in the contract.
What the challenge is
The agreed rules for how, when, in which currency and by whose account a payment moves between countries, including who bears exchange-rate movement, transfer fees and any tax withholding.
The problem
A single international payment can touch two currencies, two tax systems, two banks and sometimes an intermediary. Each adds a cost, a delay or a form. New freelancers often discover these one at a time, after the money is due.
Why it is harder than it looks
- Currency moves between invoice and payment. Payment terms of 30 or 45 days give the exchange rate time to change.
- Withholding paperwork depends on who you are. A US payer will ask a non-US freelancer for a tax form. A US freelancer serving foreign clients faces different questions.
- Fees are split unpredictably. Sending banks, receiving banks and intermediaries can each take a share.
- Rules about what counts as taxable in which country vary. Where the work is done and where the client is can both matter.
- Consumer-style protections may not apply to business payments.
The gap in most advice
Most guides list payment platforms. The decisions that shape the outcome come earlier:
- Which currency to invoice in. It is a pricing decision, not just an accounting one, because it decides who takes the currency risk.
- Which tax status the payer sees. The forms a client asks for follow from your tax status and the source of the income, and giving the wrong one, or none, can lead to withholding.
- What the contract says about fees and taxes. Silence usually means you absorb whatever comes up.
What the IRS says about Form W-8BEN
The IRS explains that Form W-8BEN is used by a foreign individual who is the beneficial owner of an amount subject to withholding. It is given to the payer, called the withholding agent, to document foreign status and, if applicable, claim a reduced rate of, or exemption from, withholding under an income tax treaty. The IRS states that without proper documentation, foreign persons may be subject to US tax at a 30% rate on certain income, and that a payer that does not receive the form may have to withhold at that rate or at the backup withholding rate.
The form generally remains in effect from the date it is signed to the last day of the third succeeding calendar year, unless a change in circumstances makes information on it incorrect. If your country of residence or other details change, tell the payer and give an updated form.
Whether US withholding applies at all can depend on where the work was performed and what kind of income it is. That is a question for a tax professional, not a form-filling exercise.
The plot: how invoice currency shifts who carries risk
Suppose you invoice the equivalent of $10,000 in your client's currency, and payment arrives 45 days later. If the client's currency weakens or strengthens 5% against your home currency in that time, the value you receive changes. This is an illustration, not a forecast.
Illustrative: a 5% currency move applied to a $10,000 invoice. If you invoice in your own currency, the client carries this movement instead of you.
A 5% swing is $500 here in either direction. Over a year of invoices, movements can help or hurt, and they can erase a thin margin. If you invoice in your own currency, the client absorbs the swing and you know what you will receive. If you invoice in theirs, you take the risk and may need to price it in.
Your options for handling currency risk
| Approach | How it works | Trade-off |
|---|---|---|
| Invoice in your own currency | Client pays the amount you state | Client bears the risk; some clients prefer their own currency |
| Invoice in the client's currency | Amount fixed in their currency | You bear the risk; may win work more easily |
| Add a currency clause | Price adjusts if the rate moves beyond a set band | Fairer for long contracts; needs a clear reference rate |
| Get paid faster | Shorter terms or deposits | Less time for rates to move |
| Hold and convert later | Keep funds in the payment currency | Requires an account that can hold it; you still carry risk |
A strategy for cross-border clients
- Decide your invoice currency before quoting, and price with the risk in mind.
- Ask early what forms the client needs, and provide the correct one for your status.
- Agree who pays transfer fees, and ask the payer to send funds so you receive the full amount, if that is what you agreed.
- Shorten payment terms and use deposits on new clients.
- Record every payment, with the date, amount, rate and fees.
Step-by-step solution
- Confirm your tax status and where you live, and check with a tax professional if it is unclear.
- Choose the invoice currency, and put it in the proposal.
- Add the payment details the client needs: account details in the right currency if you have them.
- If a US client asks for a tax form, supply the correct one for your status. A foreign individual generally gives Form W-8BEN. Do not guess which form you need.
- Put these terms in the contract: currency, payment date, who pays bank and transfer fees, late fees, and who is responsible for any taxes.
- Invoice promptly and follow up on the due date. See our guide to invoicing and getting paid faster.
- Convert or hold according to your plan.
- Keep records of invoices, payments, rates and tax forms for your accountant.
- Renew your form if it expires or your circumstances change.
Common mistakes
- Invoicing in another currency without thinking about who carries the risk
- Not supplying the tax form a payer needs, then facing withholding
- Letting a form expire or ignoring a change in circumstances
- Leaving fees unmentioned in the contract
- Assuming taxes are the client's problem
- Not recording the rate and fees for each payment
- Waiting to convert money for months without a plan
Frequently asked questions
What is Form W-8BEN for?
According to the IRS, a foreign individual gives it to a withholding agent to document foreign status and, if applicable, claim a treaty reduction or exemption from withholding. Ask a tax professional whether it applies to you.
How long does a W-8BEN last?
Generally from the date signed until the end of the third following calendar year, unless something on the form changes.
Will a foreign client withhold tax from my payments?
It depends on their country's rules and your status. Ask the client what they require, and ask a tax professional how it affects you.
Should I invoice in my currency or theirs?
It decides who carries exchange-rate risk. Your own currency gives you certainty. Theirs may be easier to sell but shifts the risk to you.
Do I still report foreign income?
Generally yes. The IRS says US citizens and residents abroad report worldwide income, and the same principle applies to US-based freelancers with foreign clients. Ask a professional about your case.
