Paying Chilean Contractors from a US Company: Treaty & IVA Guide

Why this guide exists

Chile has become one of the strongest engineering and product talent markets in Latin America for US companies. Santiago has a dense developer community, Chile sits in a time zone close to US Eastern time, and the country has a stable, business-friendly reputation in the region. For a US company building a nearshore team in the Americas, Chile is an easy place to start.

The compliance picture changed for the better at the end of 2023. After more than a decade in limbo, the US-Chile income tax treaty finally entered into force, so Chile is now a treaty country. The freelancer setup is standard and well documented, with the independent professional issuing a boleta de honorarios through the Servicio de Impuestos Internos. The pieces that look unfamiliar, such as the provisional retencion on professional fees, are Chilean domestic items your contractor handles, not obligations that land on you.

This guide covers what a US company needs to pay Chilean contractors. We cover the US side (W-8BEN, treaty application), the Chile side (boleta de honorarios, RUT, the SII, IVA, the retencion), and the payment rail decision. This is general information, not tax or legal advice. If you want to skip the assembly and let a platform handle it, Omnivoo Contract Management handles SOW drafting, W-8BEN collection, invoice capture, and FX settlement for a flat $49 per contract.

US side: what you need to do as the payer

Step 1. Collect a W-8BEN before the first payment

Before any invoice is paid, the Chilean contractor must complete Form W-8BEN and return it to you. The form certifies the contractor is the beneficial owner of the income, is a tax resident of Chile, and is not a US person. The IRS Form W-8BEN page has the current form and instructions.

The W-8BEN is valid for three calendar years after signature. If your contractor operates through a Chilean company (a SpA, Limitada, or similar), the form is Form W-8BEN-E, the entity equivalent, available on the IRS W-8BEN-E page. Our W-8BEN checklist walks through what to verify before the first payment.

Part II of the W-8BEN is where the contractor claims treaty benefits, citing Chile as the treaty country. This is filled in only when treaty benefits are needed on US source income.

Step 2. Confirm the work is performed in Chile

Under IRS source of income rules for personal services, services income is sourced to the place where the services are physically performed. If your Chilean contractor does the work entirely from Santiago, Valparaiso, Concepcion, or anywhere else in Chile, the income is Chilean source income from the US perspective.

Services performed outside the US by a nonresident alien are foreign source income and are not subject to US withholding or Form 1042-S reporting.

For a typical pure services engagement where the Chilean contractor never sets foot in the US, the result is: no withholding, no Form 1042-S, no 1099-NEC. The new treaty sits in the background but does not change this analysis.

If the contractor visits the US for an onsite sprint, the days physically worked inside the US are US source days. Those days have to be allocated and may trigger withholding and a 1042-S, so keep a simple onsite-days log.

Step 3. Know the treaty for the edge cases

The US-Chile income tax treaty governs the cases where your payment generates US source income. It was signed in 2010 and, after US Senate approval in 2023, entered into force on 19 December 2023 per the US Treasury announcement. Per that announcement, the treaty is effective for taxes withheld at source for amounts paid or credited on or after 1 February 2024, and for other taxes for taxable periods beginning on or after 1 January 2024. Chile now appears on the IRS list of income tax treaties A to Z.

This was the first new comprehensive US bilateral tax treaty to enter into force in over a decade, which is why many founders who hired Chilean contractors before 2024 are not aware Chile is now a treaty country. For background on how treaties work in general, see our income tax treaty glossary entry.

For services payments where US withholding does apply, the Chilean contractor files Form 8233 to claim treaty benefits on the services portion, using the IRS Form 8233. For royalty type payments, the contractor relies on Form W-8BEN with the relevant treaty article entered in Part II. The contractor’s Chilean accountant identifies the correct article. For more on this mechanic, see our Form 8233 treaty exemption guide.

For independent personal services, the treaty generally allocates taxing rights so that a Chilean resident’s service income is taxable in the US only to the extent it is attributable to a fixed base or US presence the contractor maintains in the US. For a contractor working entirely from Chile with no US presence, there is no US source income to begin with, so treaty article citations are not needed. The treaty only enters the picture when US withholding would otherwise apply.

Chile side: what your contractor handles

You as the US payer are not in scope for most Chilean taxes. The Chilean contractor is. Understanding the landscape helps you have an informed conversation about invoice format, IVA treatment, and the contractor’s setup.

The RUT, the SII, and the boleta de honorarios

Most Chilean freelancers working with international clients operate as an independent professional (trabajador independiente). They register their activity with the Servicio de Impuestos Internos (SII), use their RUT (Rol Unico Tributario, the tax number), and issue a boleta de honorarios (fee receipt) for each engagement through the SII portal.

The boleta de honorarios is the contractor’s invoice. You as the US payer do not need to know the internal mechanics. You only need to receive a valid boleta and keep it in your packet alongside the W-8BEN and services agreement.

IVA 19 percent and why professional fees sit outside it

Chile’s standard IVA (VAT) rate is 19 percent under Decree Law 825, confirmed on the SII IVA rate page. IVA applies to the sale of goods and a broad range of services.

For a typical independent professional billing on a boleta de honorarios, the income is taxed under Chile’s second-category income rules rather than IVA, so a normal freelance engagement is invoiced without IVA. A contractor who runs a registered company or sells goods may instead be inside the IVA system. In that case the export of services to a US customer is generally treated as outside the scope of Chilean IVA, but the exact treatment depends on the contractor’s registration and activity classification, which their accountant confirms.

The retencion on professional fees

Chile applies a provisional withholding (retencion) on professional fees paid on a boleta de honorarios. This is the mechanism that funds an independent worker’s own pension and social cover, and it is settled on the worker’s annual Chilean tax return.

Under the SII gradual-increase schedule, the retencion rate on professional fees has been rising year over year, on a path toward 17 percent later this decade. We are not stating a single fixed rate here because it changes annually and the current year’s figure should be confirmed on the SII boletas de honorarios page.

The important point for you as a US payer: the retencion is a Chilean domestic mechanism. When a Chilean company pays a boleta de honorarios, that payer withholds and remits the retencion. When you pay directly from the US, you are not a Chilean payer operating inside that system. The contractor reconciles their provisional payments on their Chilean return. Confirm with your contractor how their boletas are structured so the documentation lines up.

The payment rail decision

There are a few real options for paying a Chilean contractor from a US bank account. Chile uses the Chilean peso (CLP).

For USD-denominated invoices, a provider that lets the contractor hold a USD or multi-currency balance gives the most flexibility. For CLP payouts, choose a rail that converts USD to CLP at a fair rate into the contractor’s Chilean bank account. A SWIFT wire remains a fallback for one-off larger payments, though it loses the most to FX margin. For a deeper comparison, see our guide on FX margin in international contractor payments.

Misclassification risk in Chile

Chile, like much of Latin America, distinguishes a genuine independent contractor from a disguised employment relationship, and the labour authorities can reclassify a relationship that walks and talks like employment. The risk is highest when the contractor has only one client (your US company), works fixed hours under your direction, uses your equipment, and is integrated into your team like an employee. A reclassification can carry retroactive entitlement to severance, leave, and social contributions.

The mitigations are the same as in other markets: a properly drafted services agreement that establishes the contractor relationship in substance, a scope tied to deliverables not hours, evidence the contractor has other clients, and a documented review at six and twelve months. For more depth, see our guide on drafting an SOW for global contractors. The Omnivoo Contract Management SOW templates bake these protections in by default, including clear IP assignment and a governing law clause.

End-to-end workflow

Here is the clean version for a US company onboarding its first Chilean contractor.

1. Send the contractor a B2B services agreement that defines deliverables, payment, IP assignment, and termination, anchored by a master service agreement and a statement of work.
2. Collect a signed W-8BEN before any payment moves. Part II references Chile as the treaty country only when US source income is involved.
3. Confirm the contractor is registered with the SII, has a RUT, and can issue a boleta de honorarios for each payment.
4. Pick a payment rail (Wise, Payoneer, or another USD or CLP provider) and onboard the contractor’s payout details.
5. Pay the invoice on schedule. Keep the W-8BEN, services agreement, boleta de honorarios, and payment receipt together as a packet.
6. Review the engagement quarterly for misclassification risk and refresh the W-8BEN every three years.

If you are also comparing rails across countries, our global contractor payment methods compared 2026 guide covers the broader options, and our guide on how to pay international contractors from the US walks the general framework. If you pay contractors elsewhere in Latin America, see our guides on paying Argentine, Brazilian, Colombian, and Mexican contractors, plus our regional overview on paying Latin American contractors from the US.

When a platform pays for itself

A US founder paying one Chilean contractor can do this manually. A US team paying five or more Chilean contractors faces enough W-8BEN refreshes, boleta de honorarios confirmations, and FX margin questions that a platform pays for itself within a few months.

Omnivoo Contract Management costs a flat $49 per contract. We draft the B2B services agreement with Chile-specific IP and misclassification clauses, collect the W-8BEN, capture the boleta de honorarios on every payment, run the FX payment through a USD or CLP rail to avoid SWIFT leakage, and store the full packet for audit. Transaction fees are passed through at cost, with no FX markup and no subscription.

A simple sanity check

Three questions for every Chilean contractor relationship.

1. Is there a signed W-8BEN on file and is it less than three years old?
2. Will all the work be performed in Chile for the foreseeable future?
3. Are we paying through a rail that handles USD or CLP cleanly and captures the boleta de honorarios for every payment?

If yes to all three, you are in great shape on the US-Chile stack. The remaining work is misclassification hygiene over time.
