International payees

Paying foreign contractors: when U.S. withholding and reporting apply

Where the contractor performs the services generally determines whether the compensation is U.S. source or foreign source (https://www.irs.gov/individuals/international-taxpayers/source-of-income-personal-service-income). Services performed entirely outside the United States are generally foreign source and normally fall outside chapter 3 withholding and Form 1042-S reporting (https://www.irs.gov/instructions/iw8 and https://www.irs.gov/instructions/i1042s). Services performed in the United States create U.S. source compensation that requires a withholding and reporting review (https://www.irs.gov/individuals/international-taxpayers/pay-for-personal-services-performed). Mixed-location work requires an accurate allocation, usually on a time basis (https://www.irs.gov/individuals/international-taxpayers/source-of-income-personal-service-income).

This page explains the rules for firm review workflows. It is not tax or legal advice.

Who this page is for

This page is for accounting and bookkeeping firms whose clients pay non-U.S. contractors for services, including developers, designers, consultants, translators, and similar independent providers. It covers the payer-side chapter 3 decision for independent contractor payments. Employee payroll, immigration status, the contractor's home-country taxes, and client-specific conclusions belong with a qualified tax professional.

Two questions decide the file

First, determine whether the payee is a U.S. person or a foreign person. Form W-9 is for U.S. persons, including resident aliens, and the requester instructions route foreign persons to the Form W-8 series or Form 8233; the deeper form-routing analysis belongs in W-8BEN vs W-9 (https://www.irs.gov/pub/irs-pdf/iw9.pdf).

Next, determine where the services are performed. That fact controls the source of personal-services income and drives the chapter 3 withholding and reporting review (https://www.irs.gov/individuals/international-taxpayers/source-of-income-personal-service-income).

Source follows the place of performance

The place where personal services are performed generally determines the source of the income, regardless of where the contract was made, the place of payment, or the residence of the payer (https://www.irs.gov/individuals/international-taxpayers/source-of-income-personal-service-income). A U.S. client, a U.S. bank account, and a contract signed in the United States do not independently make the compensation U.S. source. The engagement file should record where the contractor performed the work through contract terms, statements of work, invoices, and other contemporaneous records. Publication 515 covers the source rules for withholding agents (https://www.irs.gov/publications/p515).

Work performed entirely outside the United States

When the services are performed entirely outside the United States, the compensation is foreign source under the personal-services source rule (https://www.irs.gov/individuals/international-taxpayers/source-of-income-personal-service-income). For a nonresident alien individual, the IRS states that foreign source income is normally outside chapter 3 withholding under section 1441(a) and normally does not require an information return (https://www.irs.gov/individuals/international-taxpayers/foreign-source-income-form-1042-s-reporting-not-required).

Documentation has two separate jobs. Valid foreign-status documentation supports the payee's exemption from Form 1099 reporting and backup withholding (https://www.irs.gov/individuals/international-taxpayers/withholding-and-reporting-obligations). Work-location records support the source determination (https://www.irs.gov/individuals/international-taxpayers/source-of-income-personal-service-income). If a withholding agent cannot reliably associate an amount subject to chapter 3 with valid documentation, the chapter 3 instructions generally require withholding at 30 percent (https://www.irs.gov/instructions/iw8).

Work performed in the United States

Compensation paid to a nonresident alien individual for labor or personal services performed in the United States is generally subject to withholding at 30 percent unless the payment is exempt from NRA withholding or subject to graduated withholding. The rule applies regardless of the payer's residence, where the contract was made, or the place of payment (https://www.irs.gov/individuals/international-taxpayers/pay-for-personal-services-performed).

U.S. source compensation for independent personal services paid to a foreign person is generally reportable on Form 1042-S under the current instructions (https://www.irs.gov/instructions/i1042s). Form 1042-S orientation covers that form; this page stops at the routing decision. The filer-side mechanics are covered in the Form 1042-S instructions.

A treaty or another exception may change the withholding result, and any claim requires current documentation reviewed by the client's tax professional (https://www.irs.gov/publications/p515). U.S.-performed services can also raise an effectively connected income analysis when the activities are considerable, continuous, and regular; ECI is taxed at graduated rates on a net basis (https://www.irs.gov/individuals/international-taxpayers/effectively-connected-income-eci). Chapter 4, commonly called FATCA, can affect certain foreign-entity payments and belongs with the client's tax professional (https://www.irs.gov/publications/p515).

Work performed partly in and partly outside the United States

If personal services are performed partly in the United States and partly outside it, the payer must make an accurate allocation of the compensation. In most cases, the allocation uses time: total compensation multiplied by the fraction of service days worked in the United States (https://www.irs.gov/individuals/international-taxpayers/source-of-income-personal-service-income). The client's tax professional should determine the allocation and resulting withholding treatment. The firm should preserve the underlying days, locations, and deliverables while the engagement is active.

The firm workflow for a vendor list with foreign payees

Step	Firm action
1. Identify	Review each client's vendor list for likely foreign payees before year-end work begins.
2. Confirm location	Ask where the services were performed and whether any service days occurred in the United States.
3. Preserve evidence	Keep contracts, statements of work, invoices, service dates, and work-location records with the vendor file.
4. Route U.S. and mixed cases	Send every U.S.-performed or mixed-location engagement to the client's tax professional before further payments when practical.
5. Clean the 1099 workflow	Keep a foreign payee out of the Form 1099 preparation pipeline only after the file contains reliable foreign-status documentation and the service-location review is complete (https://www.irs.gov/individuals/international-taxpayers/withholding-and-reporting-obligations).

Keep the U.S. person side ready for review

W9Finder supports private W-9 request links, tracked reminders, record flags, and review handoffs for the U.S. person side of the vendor file. When the firm identifies a likely foreign payee, route that record outside W9Finder to the client's tax professional for international documentation, withholding, and reporting decisions. W-8 collection and storage remain outside W9Finder. Explore W9Finder.

FAQ

Do foreign contractors get a Form 1099-NEC?

A foreign person with reliable foreign-status documentation is exempt from Form 1099 reporting and backup withholding (https://www.irs.gov/individuals/international-taxpayers/withholding-and-reporting-obligations). The firm must then determine where the services were performed. U.S. source compensation paid to a foreign person can enter the chapter 3 and Form 1042-S process, while foreign source compensation normally falls outside that reporting path (https://www.irs.gov/individuals/international-taxpayers/source-of-income-personal-service-income and https://www.irs.gov/instructions/i1042s).

Does paying in U.S. dollars or from a U.S. bank account make the income U.S. source?

The place where the services are performed generally determines the source, regardless of where the contract was made, the place of payment, or the residence of the payer (https://www.irs.gov/individuals/international-taxpayers/source-of-income-personal-service-income). A U.S. client paying from a U.S. account for services performed entirely abroad is generally paying foreign source compensation.

What if the contractor works partly in and partly outside the United States?

The compensation requires an accurate allocation between the U.S. and foreign service periods. In most cases, the IRS source rule uses a time basis based on service days worked in each location (https://www.irs.gov/individuals/international-taxpayers/source-of-income-personal-service-income). The client's tax professional should determine the allocation and resulting withholding treatment.

What records should the firm keep?

Keep the engagement agreement, statements of work, invoices, service dates, work locations, foreign-status documentation, and the professional's withholding and reporting determination. The source rule depends on where the services were performed, so the file should preserve that fact while the engagement is active (https://www.irs.gov/individuals/international-taxpayers/source-of-income-personal-service-income).
