Foreign contractors who perform all their work outside the United States do not get a 1099. What controls the answer is where the services are physically performed, not where the contractor lives or where you send the money. If the work happens entirely abroad, the payment is foreign-source income and falls outside 1099 reporting altogether. If any part of the work happens on U.S. soil, you switch to a different form (Form 1042-S) and generally withhold 30 percent for federal tax.
Why the 1099 Rule Doesn’t Reach Work Done Abroad
Compensation for services is classified as U.S.-source or foreign-source based on the physical location where the work is done. A nonresident alien who does all the work in their home country is earning foreign-source income, and foreign-source income paid to a foreign person is not something the 1099-NEC system was built to capture.
A business that hires a web developer in Germany, a graphic designer in the Philippines, or a consultant in Canada — and each of them completes the work in their own country — has no 1099-NEC to file for those payments. The IRS instructions for Form 1099-NEC send payers who are dealing with nonresident aliens to Form 1042-S instead.1Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC
When Payments to a Foreign Contractor Become Reportable
The moment a foreign contractor performs any portion of the work while physically present in the United States, the compensation for that work becomes U.S.-source income. A few days of on-site consulting, an in-person training, or a conference appearance is enough to pull the payment into the reporting and withholding system.
You still do not file a 1099-NEC. You report the payment on Form 1042-S, which is the return designed for U.S.-source income paid to foreign persons.2Internal Revenue Service. Reporting Payments to Independent Contractors You also have to withhold federal tax before sending the contractor their share.
Confirming the Contractor Is Actually a Nonresident Alien
Before you rely on any of the foreign-contractor rules, confirm that the person is a nonresident alien in the first place. A foreign national who spends enough time in the U.S. can become a resident alien for tax purposes, which puts them back on the domestic side of the rules — and back on Form 1099-NEC.
The IRS uses the substantial presence test. A person is treated as a U.S. resident for tax purposes if they are physically present in the country for at least 31 days during the current year and at least 183 days across a three-year lookback period. The 183 figure is weighted: all days in the current year, one-third of the days in the prior year, and one-sixth of the days in the year before that.3Internal Revenue Service. Substantial Presence Test A contractor who meets the test is treated like a domestic taxpayer and would receive a 1099-NEC. A contractor who fails it, and who is not a citizen or green card holder, is a nonresident alien.
Collecting W-8 Forms Before You Pay
The paperwork that documents foreign status — and justifies not issuing a 1099 — is the W-8 series. Individuals sign Form W-8BEN. Foreign entities such as corporations and partnerships sign Form W-8BEN-E. These are certificates of foreign status. You keep them in your records; you do not file them with the IRS.
On the W-8BEN, the contractor gives their full legal name, permanent residence address in their home country, country of citizenship, and date of birth. If they want to claim a reduced withholding rate under a tax treaty, they also have to provide a foreign or U.S. taxpayer identification number.4Internal Revenue Service. Claiming Tax Treaty Benefits Collect the form before the first payment. Without one in your file, you may be forced to withhold at the full 30 percent rate no matter what treaty the contractor might have qualified under.
How Long the Form Stays Valid
A Form W-8BEN generally remains valid from the date the contractor signs it through the last day of the third succeeding calendar year. A form signed on June 15, 2026, stays valid through December 31, 2029. If any information on the form becomes wrong, such as a change in residence country, the contractor has to send you a new one within 30 days.5Internal Revenue Service. Instructions for Form W-8BEN
How Long to Keep It
You need to retain signed W-8 forms for as long as they are relevant to determining your withholding liability. In practice, that means keeping them through the form’s validity period and for as long as the IRS could still assess additional tax against you, which is generally three years after you file the related Form 1042.6Internal Revenue Service. Instructions for the Requester of Forms W-8BEN, W-8BEN-E, W-8ECI, W-8EXP, and W-8IMY
Withholding 30 Percent on U.S.-Source Payments
When you pay a foreign contractor for services performed in the United States, federal law requires you to withhold 30 percent of the gross payment and send it to the IRS on the contractor’s behalf.7Office of the Law Revision Counsel. 26 USC 1441 – Withholding of Tax on Nonresident Aliens Withholding applies to the total amount paid, not just profit. On a $10,000 payment, $3,000 goes to the IRS and $7,000 goes to the contractor. You deposit the withheld tax through the Electronic Federal Tax Payment System (EFTPS) on the schedule set out in the Form 1042 instructions.
If You Don’t Have Documentation
No signed W-8, no reduced rate. You must withhold at the full 30 percent. A withholding agent who has reason to know that a claim of foreign status or a reduced treaty rate is unreliable also has to withhold at the full 30 percent.8eCFR. 26 CFR 1.1441-7 – General Provisions Relating to Withholding Agents
If you cannot even determine whether the payee is a foreign person or a U.S. person, the IRS presumption rules generally require you to treat the payee as a U.S. person subject to backup withholding at 24 percent.9Internal Revenue Service. Tax Withholding Types Failing to collect documentation before paying creates liability for your business. You become personally responsible for tax you should have withheld but didn’t.
Reduced Rates Under a Tax Treaty
The United States has income tax treaties with dozens of countries that may reduce the 30 percent rate or eliminate it entirely for certain kinds of income. To claim a treaty benefit, the contractor has to give you a U.S. or foreign taxpayer identification number on their W-8BEN. Without any TIN, they cannot receive a reduced rate.4Internal Revenue Service. Claiming Tax Treaty Benefits
For independent personal services (contract labor, professional fees, consulting fees, and similar compensation) the contractor may also need to file Form 8233 with you to claim a treaty exemption. Form 8233 is the specific form nonresident alien independent contractors use to claim that their service compensation is exempt from withholding under a treaty.10Internal Revenue Service. Instructions for Form 8233 Review the applicable treaty and confirm eligibility before applying any reduced rate. If you apply a treaty benefit incorrectly, you are liable for the difference.
Filing Form 1042-S and Form 1042
Form 1042-S is the information return you file with the IRS to report U.S.-source income paid to foreign persons, including nonresident alien contractors. You file a separate 1042-S for each contractor and give a copy to the contractor for their own tax filings.11Internal Revenue Service. Discussion of Form 1042, Form 1042-S and Form 1042-T The form shows the total paid, the tax withheld, and the withholding rate applied.
Alongside the individual 1042-S forms, you file Form 1042, the annual withholding tax return that summarizes all tax withheld on payments to foreign persons during the year. Form 1042-S reports each payment; Form 1042 reconciles the year’s withholding with the deposits you made. You must file Form 1042 whenever you have to file a Form 1042-S.2Internal Revenue Service. Reporting Payments to Independent Contractors
Both are due on March 15 of the year following payment. If March 15 falls on a weekend or legal holiday, the deadline moves to the next business day. You can request an extension to file Form 1042-S using Form 8809, and an extension to file Form 1042 using Form 7004. An extension of time to file does not extend the time to pay.
If you file 10 or more information returns in total during the year — 1099s, W-2s, and 1042-S forms combined — you must file electronically.12Internal Revenue Service. Electronic Reporting
What Non-Compliance Costs
Penalties for mishandling foreign contractor payments come from more than one direction: late filing, incorrect filing, failure to furnish forms to the contractor, and failure to withhold.
For late or incorrect filing of Form 1042-S, the amount rises the longer you wait:
- Filed within 30 days of the due date: $60 per form, up to $698,500 per year ($244,500 for small businesses).
- Filed after 30 days but by August 1: $130 per form, up to $2,095,500 per year ($698,500 for small businesses).
- Filed after August 1 or not filed at all: $340 per form, up to $4,191,500 per year ($1,397,000 for small businesses).
- Intentional disregard: the greater of $690 per form or 10 percent of the total amount required to be reported, with no maximum cap.
A separate penalty of up to $340 per form applies for failing to furnish a copy of Form 1042-S to the contractor by the deadline.13Internal Revenue Service. Instructions for Form 1042-S
If you fail to withhold, you become personally liable for the full amount that should have been withheld, plus interest and additional penalties. The contractor’s tax obligation effectively becomes yours. Four steps keep this straightforward: collect a W-8 before the first payment, apply the right withholding rate to any U.S.-performed work, deposit the tax on schedule, and file Forms 1042-S and 1042 by March 15.
