Paying Greek Contractors from a US Company: Treaty & FPA Guide

Why this guide exists

Greece has a growing pool of software, design, and operations talent that US companies tap into for nearshore-to-Europe work. Athens and Thessaloniki have active developer and creative communities, English is widely spoken in professional settings, and the time zone overlaps a full European working day. For a US company building a European team without a local entity, Greece is a practical place to hire.

The compliance picture is clean. Greece appears on the IRS list of income tax treaties, so it is a treaty country. The freelancer setup is standard, with the independent professional registering an AFM tax number with the AADE and reporting through myDATA. The items that look unfamiliar, such as the e-EFKA social contributions and the myDATA reporting, are Greek domestic obligations your contractor handles, not obligations that land on you.

This guide covers what a US company needs to pay Greek contractors. We cover the US side (W-8BEN, treaty application), the Greece side (AFM, the AADE, FPA, myDATA, e-EFKA), 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 Greek 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 Greece, 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 Greek company (an IKE, EPE, 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 Greece 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 Greece

Under IRS source of income rules for personal services, the place where the 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. If your Greek contractor does the work entirely from Athens, Thessaloniki, Patras, or anywhere else in Greece, the income is Greek 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 Greek contractor never sets foot in the US, the result is: no withholding, no Form 1042-S, no 1099-NEC. The 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

Greece appears on the IRS list of income tax treaties A to Z, so there is a US-Greece income tax treaty. The IRS Greece tax treaty documents page lists an income tax treaty dated 1950. The treaty governs the cases where your payment generates US source income. For background on how treaties work in general, see our income tax treaty glossary entry.

For services payments where US withholding does apply, the Greek contractor files Form 8233 to claim treaty benefits on the services portion, using the IRS Form 8233. For other income types, the contractor relies on Form W-8BEN with the relevant treaty article entered in Part II. The contractor’s Greek accountant identifies the correct article. We are not citing specific article numbers or rates here because the cases that need them are rare and the contractor’s accountant pins down the correct provision. For more on this mechanic, see our Form 8233 treaty exemption guide.

For a contractor working entirely from Greece 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.

Greece side: what your contractor handles

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

The AFM, the AADE, and the invoice

Most Greek freelancers working with international clients operate as a registered self-employed professional. They register their activity with the AADE (Independent Authority for Public Revenue), receive an AFM (Arithmos Forologikou Mitroou, the tax registration number), and issue invoices to clients. They also register with e-EFKA, the Greek social security agency, as a self-employed contributor.

The invoice the contractor issues is your document for the engagement. You as the US payer do not need to know the internal mechanics. You only need to receive a valid invoice and keep it in your packet alongside the W-8BEN and services agreement.

FPA (VAT) and why B2B export sits outside it

Greece’s standard FPA (Foros Prostithemenis Axias, the Greek VAT) rate is 24 percent according to the AADE basic VAT rates page. FPA applies to the supply of goods and a broad range of services within Greece.

For services supplied to a US business customer, the place of supply under the EU VAT rules that Greece follows is generally where the customer is established, which puts the supply outside the scope of Greek FPA. In practice the contractor issues an invoice marked as outside scope or reverse charge, and you do not pay Greek VAT on it. The exact treatment depends on the contractor’s registration and activity classification, which their accountant confirms.

myDATA reporting and e-EFKA contributions

myDATA is the AADE digital platform Greek businesses use to report invoice and accounting data, and Greece has been extending structured electronic invoicing obligations for domestic transactions. This is a domestic reporting mechanism that the contractor handles for their own records. As a foreign customer you do not file anything in myDATA, and a cross-border invoice to your US company sits outside the domestic e-invoicing flow. Your contractor still issues you a normal invoice. Confirm the format with the contractor’s accountant.

Self-employed people in Greece pay social contributions to e-EFKA on their own income. This is the contractor’s own obligation. You as the US client do not pay or contribute to e-EFKA and have no Greek social security reporting obligation for an independent contractor.

The payment rail decision

There are a few real options for paying a Greek contractor from a US bank account. Greece is in the euro area, so contractors typically hold euro accounts.

Greece is part of SEPA (Single Euro Payments Area), so EUR-denominated transfers from any EUR-supporting provider land in the contractor’s Greek bank account quickly and cheaply. For USD-denominated invoices, a provider that lets the contractor hold a USD or multi-currency balance, or converts USD to EUR at a fair rate, gives the most flexibility. 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 Greece

Greece, like the rest of the EU, distinguishes a genuine independent contractor from a disguised employment relationship, and the labour authorities can reclassify a relationship that looks like employment in substance. 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 leave, notice, 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 Greek 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 Greece as the treaty country only when US source income is involved.
3. Confirm the contractor is registered with the AADE, has an AFM, and can issue a valid invoice for each payment.
4. Pick a payment rail (Wise, Payoneer, or a SEPA-aware EUR provider) and onboard the contractor’s payout details (Greek IBAN).
5. Pay the invoice on schedule. Keep the W-8BEN, services agreement, invoice, 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 Europe, see our guides on paying Italian, Spanish, Portuguese, and Romanian contractors.

When a platform pays for itself

A US founder paying one Greek contractor can do this manually. A US team paying five or more Greek contractors faces enough W-8BEN refreshes, invoice 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 Greece-specific IP and misclassification clauses, collect the W-8BEN, capture the invoice on every payment, run the FX payment through a SEPA or USD-to-EUR 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 Greek 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 Greece for the foreseeable future?
3. Are we paying through a rail that handles EUR via SEPA or USD-to-EUR cleanly and captures the invoice for every payment?

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