How to pay international contractors: methods, costs, W-8BEN and 1099 rules

To pay international contractors from the US, collect Form W-8BEN before the first payment, pay against invoices by a method that converts close to the mid-market rate, and keep records. Contractors who are not US persons and work entirely outside the US generally need no Form 1099 and no US withholding.

Key takeaways

  • To pay international contractors from the US, confirm the person is genuinely independent under their own country's law, collect Form W-8BEN before the first payment, and pay against invoices by a method that converts near the mid-market rate. Contractors who are not US persons and work entirely outside the US generally need no Form 1099 and no US withholding.
  • The label in your contract doesn't decide classification. If you control how, when and where someone works, their country can treat them as your employee and claim payroll taxes, social contributions and benefits.
  • Work a foreign contractor does while physically in the US is US-source income, which generally means 30% withholding and Form 1042-S unless a tax treaty exempts it.
  • In the worked example, paying three contractors $8,000 a month by bank wire costs about $420 in fees and markups, against about $76 through a low-margin transfer service.
  • An employer of record becomes the legal employer in the worker's country and runs local payroll, which suits long-term, full-time roles you direct closely.

Paying someone abroad for work takes four decisions: whether they are really a contractor, which tax form to collect, how to move the money and in which currency. A wrong answer on the first can bring back taxes and penalties in the worker's country, and careless answers on the last two can cost several percent of every invoice. This guide takes each decision in turn for a US business, then prices a month of payments to three contractors in three countries.

Is the person a contractor or an employee?

The worker's own country decides, using its own tests, and a contract that says independent contractor doesn't settle the question.

Most countries look past the label to how the work actually happens. Canada's tax agency, for example, weighs who controls the work, who supplies the tools, whether the worker can hire helpers, who carries financial risk and whether the worker can profit from managing the job well, and it looks at the working relationship in practice rather than what the parties intended. In the EU, a 2024 directive requires member states, by December 2, 2026, to presume employment for people working through digital labour platforms when the facts show direction and control.

Signs that tend to point toward employment:

  • You set the hours, approve time off or forbid work for other clients.
  • The person works only for you, full time, with no end date.
  • They use your equipment, email domain and internal tools and appear in your org chart.
  • You pay a fixed monthly sum whatever the output, with no invoices.
  • They manage your staff or present themselves as your employee.

If a contractor is reclassified, the bill can include the employer social contributions and payroll taxes that should have been paid, mandatory benefits such as paid leave, interest and penalties. A second risk is corporate tax. Under the dependent-agent rule in most tax treaties, modeled on Article 5 of the OECD Model Tax Convention, a person who habitually concludes contracts for your company in their country can create a permanent establishment there, making part of your profit taxable locally. Sales roles carry this risk most.

Which tax forms do you need for a foreign contractor?

Collect Form W-8BEN from an individual, or Form W-8BEN-E from a company, before the first payment, and keep it on file.

The form certifies that the contractor is not a US person. It doesn't go to the IRS; it stays in your records. A W-8BEN generally remains valid until the last day of the third calendar year after the year it is signed (IRS, as of Nov 1, 2026). A change in circumstances, such as a move to the US, ends it sooner, and the contractor must tell you within 30 days.

What you report depends on who the contractor is and where the work is physically done:

ContractorWhere the work is doneUS withholdingInformation return
Nonresident individual or foreign companyEntirely outside the USNoneNone: no Form 1099-NEC or 1042-S
Nonresident individualPartly or wholly in the US30% on pay for the US days, unless a treaty exemption is claimed on Form 8233Form 1042-S for the US-source part
US citizen or green card holder living abroadAnywhereNone, with a valid Form W-9 on fileForm 1099-NEC once payments reach the threshold
A payee who won't provide a W-8 or W-9AnywhereMay be presumed a US person and face 24% backup withholdingForm 1099-NEC

Pay for services is sourced where the work is physically performed. A contractor in Manila who never sets foot in the US earns foreign-source income, which the IRS says is not subject to US withholding and need not be reported on Form 1042-S. Form 1099-NEC doesn't apply either, because it reports payments to US persons.

The picture changes if the contractor works from the US, even briefly. Pay for the days worked here is US-source income. The IRS allocates it by days, you generally withhold 30% and report it on Form 1042-S, and the contractor claims any treaty exemption on Form 8233 rather than a W-8BEN. Forms 1042-S for payments made in 2026 are due March 15, 2027.

US citizens and green card holders are US persons wherever they live. Collect Form W-9 from them instead, and file Form 1099-NEC once your payments reach the threshold: $2,000 for payments made in 2026, up from $600 (IRS, as of Nov 2, 2026). If any payee won't give you a valid form, you may have to apply backup withholding at 24% and report it on Form 945.

How can you pay contractors abroad?

Most US businesses use one of five methods, and the real cost of each is the fee plus the gap between the rate you get and the mid-market rate.

MethodHow it worksMain cost driversWatch for
Bank wire (SWIFT)Your bank sends the money, often through one or more correspondent banksOutgoing fee, intermediary deductions, the bank's exchange-rate markupDeductions that leave the contractor short of the invoice
Business transfer serviceThe provider takes dollars from your account and pays out locally from its own accounts abroadA per-payment fee and an exchange-rate margin that varies by currencyMargins that rise for less common currencies
Contractor payment or payroll platformA platform collects invoices and tax forms and pays everyone in one batchMonthly fees per contractor plus exchange-rate marginsFees that add up for small, infrequent invoices
Dollars to a dollar accountYou send dollars; the contractor's bank or wallet holds or converts themYour sending fee, then the contractor's receiving and conversion costsCosts you don't see but the contractor prices in
StablecoinsYou send a dollar stablecoin to the contractor's walletSpreads when buying and selling, plus network feesLocal rules on cashing out; see stablecoin transfers

Wires come with three charge options, chosen when the wire is sent, that decide whether you or the contractor absorbs intermediary fees; our guide to international wire transfer fees explains them.

Business payments also sit outside the CFPB's Remittance Rule, which covers only transfers sent for personal, family or household purposes. You don't get its disclosures, its 30-minute cancellation right or its error procedures, so read the provider's own terms on errors and recalls. Our guide to remittance transfer rights shows what consumers get instead.

Should you pay in dollars or the contractor's currency?

Paying in the contractor's currency puts the conversion, and the exchange-rate risk, on your side; paying in dollars hands both to the contractor.

A contractor paid in dollars usually receives whatever their own bank's conversion delivers after its fees, and many price that cost into their rates. Paying in local currency lets you pick a provider with a small markup and lets the contractor invoice a fixed amount, but your dollar cost then moves with the exchange rate. Each percentage point of markup costs 1% of the payment, whichever side bears it. The table applies two markups to Philippine peso payments at the latest mid-market rate.

Check any quote against the mid-market rate in our currency converter, or on the dollar to rupee page for contractors in India. Our guide to exchange-rate markups shows how to turn a quoted rate into a percentage.

Put the currency in the contract. One middle path is to invoice in the contractor's currency and review the rate once or twice a year, accepting that your cost drifts in between. If foreign-currency costs are a large part of your budget, our guide to currency risk for small businesses covers forwards and other hedges.

What does it cost to pay three contractors abroad each month?

With the illustrative fees below, bank wires cost about 5% of the monthly invoices, against about 1% through a low-margin transfer service.

Worked example: Paying $8,000 a month to contractors in India, Mexico and the Philippines

A US startup pays a developer in India $4,000, a designer in Mexico $2,500 and a support specialist in the Philippines $1,500 each month, converted into local currency. The fees and markups are assumptions for illustration, not quotes. Costs are counted whoever ends up bearing them, the way the World Bank prices transfers.

ContractorInvoiceBank wire: $45 fee, 3% markup, $15 intermediary deductionTransfer service: $4 fee, 0.8% markup
India$4,000$45 + $120 + $15 = $180$4 + $32 = $36
Mexico$2,500$45 + $75 + $15 = $135$4 + $20 = $24
Philippines$1,500$45 + $45 + $15 = $105$4 + $12 = $16
Monthly total$8,000$420, or 5.25%$76, or 0.95%
Yearly total$96,000$5,040$912
  • Markup cost = invoice × markup, for example $4,000 × 3% = $120
  • Moving all three contractors to the transfer service saves $344 a month, or $4,128 a year
  • Flat fees hit the smallest invoice hardest: by wire, $105 is 7.0% of the $1,500 payment
  • Unless the wire is sent with all charges paid by you, the $15 intermediary deduction comes out of what the contractor receives

If you top up payments so each contractor receives the full invoice value, these costs land on you; if you don't, they land on the contractor, who will tend to raise their rates. Either way the cheaper route saves real money once payments recur every month.

What should you check before the first payment?

Screen the contractor against US sanctions lists, confirm their bank details through a second channel and make sure the paperwork matches the working arrangement.

  • Sanctions. US persons may not deal with anyone on OFAC's sanctions lists and, generally, with anyone in a region under comprehensive sanctions, which OFAC lists as Cuba, Iran, North Korea and the Crimea, Donetsk and Luhansk regions of Ukraine. Syria's comprehensive program ended on July 1, 2025, though sanctions on listed people remain. Providers will freeze or reject a payment that matches a list.
  • Bank details. Take them from the contractor's signed onboarding form, then confirm them by phone or video call. Treat any later change that arrives by email as suspect until confirmed the same way; it is the opening move of business email compromise.
  • Name match. Pay an account in the contractor's own name or their company's name, as shown on the contract and the tax form.
  • Where the work happens. Ask the contractor to tell you before any working trip to the US, because those days change the withholding rules.

Records to keep for every contractor

Keep a written contract, an invoice for every payment, proof of each transfer and the contractor's tax form, so you can show what you paid and why.

The contractor file

  • A contract covering deliverables, fees, currency, payment timing, who bears transfer fees, assignment of intellectual property, confidentiality, termination and the governing law
  • The W-8BEN, W-8BEN-E or W-9, with the date you received it and a reminder to renew it
  • An invoice for each payment in the contractor's or their company's name, with their address and the period covered
  • The transfer confirmation showing the amount sent, the exchange rate, the fees and the reference number
  • The dollar value of each payment on the day you paid it, for your books
  • The sanctions screening result for the contractor's name and country
  • Any days the contractor worked inside the US

Pay only against an invoice and only to details already in this file. A clean file is also your best evidence that the relationship is a business-to-business one if a tax authority ever asks.

When does an employer of record make more sense?

An employer of record suits a long-term, full-time role you direct closely, where contractor status would be hard to defend.

An employer of record, or EOR, is a company that already has a legal entity in the worker's country. It becomes the worker's legal employer: it signs a local employment contract, runs payroll, withholds income tax, pays social contributions and provides statutory benefits such as paid leave. You direct the day-to-day work, and each month the EOR invoices you for the salary, the employer costs and its own fee. Setting up your own subsidiary gives full control instead, but brings local registration, accounting and payroll duties of your own.

Legal employerNone; the worker runs a businessThe EORYour subsidiary
Monthly costThe invoice plus transfer costsSalary, employer contributions and the EOR feeSalary, contributions and the cost of running the entity
Who carries employment-law dutiesThe worker, if the arrangement is genuineThe EOR, as legal employerYour subsidiary
Fits bestProject or part-time work for several clientsOne or a few employees in a countryA team large enough to justify an entity

Before signing with an EOR, ask how it handles termination, which local law may restrict, and confirm that work product and intellectual property pass to your company, since the employment contract sits between the EOR and the worker.

Frequently asked questions

Do you send a 1099 to a foreign contractor?+

Not if the contractor is a nonresident who did all the work outside the US. That pay is foreign-source income, so neither Form 1099-NEC nor Form 1042-S is required. US citizens living abroad are different and get a 1099-NEC like any US contractor.

Does a foreign contractor send Form W-8BEN to the IRS?+

No. The contractor gives the signed form to you, the payer, and you keep it on file. It stays valid until the end of the third calendar year after signing unless the contractor's circumstances change, such as a move to the US.

Can you pay international contractors in stablecoins?+

Yes, if the contractor agrees and can legally cash out where they live. The same tax forms and records apply, and the IRS treats paying for services with digital assets as a disposal, so you record a gain or loss, usually close to zero for a dollar stablecoin.

Who pays the wire fees on a payment to a contractor abroad?+

It depends on the charge option chosen when the wire is sent. Under the common shared option you pay your bank's fee and the contractor absorbs any intermediary or receiving-bank deductions, so say in the contract who covers transfer costs.

Do you need to check sanctions before paying a contractor abroad?+

Yes. US persons may not deal with people on OFAC's sanctions lists or, generally, with anyone in a comprehensively embargoed region such as Cuba, Iran, North Korea or Crimea. Screen the contractor's name before the first payment and whenever details change.
