Do You Need a 1099 for a Foreign Developer?

No, a US company usually does not file Form 1099 for a developer who is not a US person and performs the work outside the United States. Instead, collect Form W-8BEN for an individual or W-8BEN-E for a foreign company, keep it in your records, and document where the services were performed.

When is a 1099 not required for a developer outside the US?

A 1099 is generally a domestic information return. For software development services, the first question is not “Where did I send the payment?” It is “Who is the payee, and where was the work performed?”

The IRS sourcing rule for personal services is straightforward: compensation and business income from personal services are sourced where the services are performed, not where the client is based or where the payment is made (IRS, Nonresident aliens — sourcing of income). Publication 515 says the same thing for personal services: if the services are performed in the United States, the income is US-source; if services are split between US and non-US locations, allocation is required (IRS Publication 515).

So, if your company hires a backend developer in Brazil, Poland, India, or Nigeria, and that person performs all work from outside the US, the payment is generally foreign-source service income. In that common remote-hiring case, you normally do not issue Form 1099-NEC.

That does not mean you should have no paperwork. Ask the contractor to certify foreign status before payment:

IRS instructions say Form W-8BEN is used to establish that the payee is not a US person and that a payer may rely on a properly completed form to treat the payment as made to a foreign beneficial owner (IRS Instructions for Form W-8BEN). The same instructions say a US citizen, even one residing outside the United States, should not use W-8BEN and should use Form W-9 instead (IRS Instructions for Form W-8BEN).

What should US companies collect instead of a 1099?

For a foreign independent developer, your compliance file should usually include:

• A signed contract naming the foreign individual or foreign entity.
• A completed W-8BEN for an individual, or W-8BEN-E for an entity.
• Invoices showing the payee name, address, services, dates, and currency.
• A work-location representation, such as “services are performed outside the United States.”
• Payment records that match the invoices and contract.

Do not send Form W-8BEN to the IRS. The IRS instructions say the form is given to the withholding agent or payer before income is paid or credited, and not filed with the IRS (IRS Instructions for Form W-8BEN).

Also track expiration. IRS requester instructions say a Form W-8 is generally valid from the date signed until the last day of the third succeeding calendar year, unless a change in circumstances makes the form incorrect (IRS Instructions for the Requester of Forms W-8). Build that renewal into your vendor-management process.

If you hire through a talent platform, confirm who is the legal payee and what tax documentation the platform provides. OctogleHire, for example, supports flexible full-time, part-time, and contract engagements with vetted engineers; regardless of channel, your finance team should still retain the contract, invoices, and appropriate tax forms. For broader hiring process design, see how to hire remote developers and OctogleHire’s developer vetting process.

When could withholding or Form 1042-S apply?

The risk changes if the developer performs services while physically inside the United States. The IRS says payers generally must withhold tax at the 30 percent rate on compensation paid to a nonresident alien individual for labor or personal services performed in the US, unless the pay is exempt or subject to graduated wage withholding (IRS, Pay for personal services performed).

That can happen if a foreign contractor travels to the US for an onsite sprint, implementation, training, or consulting engagement. In that case, you may need to allocate compensation between work performed outside and inside the US. Publication 515 says allocation is generally made on a time basis when services are performed partly in and partly outside the United States (IRS Publication 515).

Treaty claims are another special case. Publication 515 notes that some treaties exempt independent personal services performed in the US only if the contractor’s temporary presence does not exceed a treaty-specific limit, often 183 days, and the contractor is a resident of the treaty country (IRS Publication 515). Independent nonresident alien contractors use Form 8233 to claim treaty-based withholding exemptions for personal services performed in the United States (IRS Publication 515).

Form 1042-S may enter the picture when you pay US-source income to a foreign person. IRS guidance on nonresident alien withholding says payments for personal services performed in the US may be reported on Form 1042 and Form 1042-S, while foreign-source income does not require Form 1042-S reporting in that context (IRS, Pay for personal services performed).

What if the developer is actually a US person?

Do not rely only on “lives outside the US.” A developer can live abroad and still be a US citizen, green-card holder, or US tax resident. In that case, ask for Form W-9, not W-8BEN.

For the 2026 tax year, IRS instructions for Form 1099-NEC say to file for each person in the course of business to whom you paid at least $2,000 for services performed by someone who is not your employee (IRS Instructions for Forms 1099-MISC and 1099-NEC). The IRS says Form 1099-NEC must be filed with the IRS by January 31 of the year following the tax year, and a copy must also be furnished to the recipient by January 31 (IRS Information Return Reporting).

That means your decision tree should be:

• If the developer is a US person: collect W-9 and evaluate 1099-NEC reporting.
• If the developer is a foreign person working entirely outside the US: collect W-8BEN or W-8BEN-E and usually do not file 1099-NEC.
• If the developer is foreign but performs any services in the US: ask a qualified tax adviser about withholding, treaty forms, allocation, and possible 1042-S reporting.

Next steps

Before paying a foreign developer, standardize a short onboarding checklist: identity of payee, tax form, work-location confirmation, contract, invoice format, IP assignment, and data-security obligations. If you are comparing countries or engagement models, pair that compliance checklist with your hiring plan; OctogleHire can help companies source vetted remote engineers, while your CPA or tax counsel confirms the filing treatment for your specific facts.
