6 IRS forms and publications reviewed
2 source-of-income outcomes compared

Key Takeaways
- Reporting depends on the payee's status as a US person or a nonresident alien, and on where the services are performed.
- Payments to a US-person contractor of $600 or more generally go on Form 1099-NEC; a completed Form W-9 supplies the taxpayer identification number.
- A nonresident alien who performs services entirely outside the United States generally earns foreign-source income, so the payment is usually not reported on a 1099 or subject to US withholding.
- When a payment is US-source and subject to chapter 3 withholding, Form 1042-S and Form 1042 can come into play, and a treaty claim uses Form W-8BEN.
- The worker-classification question sits underneath all of this: if a US business treats a worker as an employee, payroll withholding and reporting rules apply instead.

Paying an overseas virtual assistant
Paying an overseas virtual assistant raises a question that a domestic engagement does not: which United States information-reporting and withholding rules apply to money sent across a border. The answer turns on two facts that founders often conflate. The first is the status of the worker: is the assistant a US citizen, a resident alien, or a nonresident alien? The second is the source of the payment: were the services performed inside the United States or entirely outside it? This review explains what the Internal Revenue Service publications and forms actually establish, distinguishes those statements from practical inference, and identifies the records a business can keep to support its position.
Start with status, not with the platform
A US business does not report all contractor payments the same way. For a payee who is a US person, the familiar path is Form 1099-NEC, which reports nonemployee compensation of $600 or more paid in the course of a trade or business. Before issuing it, the business collects Form W-9 from the payee to obtain the correct name and taxpayer identification number. If the payee does not provide a taxpayer identification number, the IRS backup withholding rules can require the payer to withhold a percentage of the payment, and the business can become liable for the amount it should have withheld.
For a payee who is a nonresident alien, the analysis changes. A resident alien is treated like a US person for these purposes and is generally subject to the same reporting as a citizen. A nonresident alien is a different category, and the W-8 series of forms, rather than the W-9, documents that status. Form W-8BEN is the form an individual provides to certify foreign status and, when applicable, to claim a reduced rate under a tax treaty. A business that asks every overseas assistant for a W-9 is asking the wrong question, and a business that treats every overseas assistant as automatically exempt is guessing.
Why the place of performance matters
Under the source-of-income rules described in IRS Publication 515, compensation for personal services generally has its source where the services are performed. This is the detail that surprises founders. If a nonresident alien virtual assistant performs all work from another country, the compensation is generally foreign-source income, and the United States generally does not withhold on it. A payment can be made to a foreign account without triggering chapter 3 withholding simply because the payee is foreign, as long as the services are foreign-source.
If the same assistant travels to the United States and performs services there, the portion of the compensation attributable to US-performed services can be US-source, and different rules apply. Some categories of income, including certain payments that are not for personal services, are US-source under different tests. The practical consequence is that a business should document where the work was performed, not only who performed it.
When withholding and 1042-S reporting apply
When a payment is foreign-source personal services income to a nonresident alien, the usual outcome is that the business does not issue Form 1099-NEC and does not withhold. When a payment is US-source and is the kind of income subject to chapter 3 withholding, the business may have to withhold at the statutory rate or at a treaty rate the payee has claimed, report the payment on Form 1042-S, and file an annual Form 1042 return. A properly completed Form W-8BEN supports a treaty claim, but only for the benefits the treaty actually provides and only for a payee who is a resident of the treaty country under the treaty's own rules.
This is why a single habit helps: collect the right form before the first payment, keep it current, and re-verify when the facts change. A form on file that no longer matches the relationship is not protection.
The classification question underneath
None of the reporting analysis resolves whether the worker is an employee or an independent contractor. That question is governed by the IRS common-law test and, for wage and hour purposes, the Department of Labor economic realities test. If a US business treats an overseas worker as an employee, employment tax withholding and reporting rules apply, and the analysis is materially different from the contractor path. Our companion review of virtual assistant classification explains those tests, and our cost comparison in the virtual assistant cost review frames the all-in economics that often drive the decision.
There is also a state layer. Even when federal reporting is straightforward, a US business may have state income tax withholding obligations or registration requirements when a worker performs services in a state, and state rules do not always follow the federal source analysis. Founders should check the states where the business operates and where work is performed.
Records a business should keep
The IRS publications point to a consistent set of records. Keep a completed W-9 or the appropriate W-8 form for every payee, with the certification date and the payee's status. Keep the contract or statement of work that describes the services and where they are performed. Keep payment records that show amounts, dates, and the method of payment. Keep any treaty claim and the analysis behind it. If a third-party payment platform is used, recognize that the platform may issue its own information return and that the payer's obligations can depend on the platform's role; the reporting landscape for platform payments has changed in recent years, so confirm current guidance rather than relying on an old threshold. And keep these records long enough to support the returns on which they are reflected.
Common misunderstandings
Several beliefs recur. One is that any payment to a foreign person is tax-free. The source rules, not the destination account, determine withholding. Another is that a W-8BEN alone eliminates tax. It supports a status or treaty claim, but the underlying facts still have to qualify. A third is that using a payment platform transfers all responsibility. Platforms can change who files what, but the business still owns its classification and record-keeping decisions. A fourth is that a contractor agreement settles the worker's status. As with classification generally, the facts of the relationship control.
Methodology and limits
This review examined primary IRS guidance, including the instructions and descriptions for Form W-9, Form 1099-NEC, Form W-8BEN, Form 1042-S, Form 1042, Publication 515, and the IRS page on independent contractor status, along with the Small Business Administration's hiring guidance. Each source was checked on September 22, 2026. The review summarizes the federal framework at a general level; it does not provide tax advice, does not analyze a specific treaty, payment, or payee, and does not cover every state or local requirement. Tax law and administrative guidance change, and platform reporting thresholds in particular have been adjusted in recent years, so a business should confirm current rules with a qualified tax professional before relying on this synthesis.
Frequently asked questions
Do I send a 1099-NEC to an overseas virtual assistant? Generally not if the assistant is a nonresident alien and the services are performed outside the United States, because the payment is foreign-source. Use the W-8 series to document foreign status.
What form do I collect from an overseas contractor? Form W-8BEN for an individual, which certifies foreign status and can claim a treaty benefit where one applies.
Is a foreign assistant always exempt from US tax? No. If services are performed in the United States, the compensation can be US-source and subject to withholding or reporting.
What if the assistant is a US citizen living abroad? A US citizen is a US person. The usual 1099-NEC and W-9 rules generally apply even if the person works from another country.
