Paying Hungarian Contractors from a US Company: Terminated Treaty & AFA Guide

Why this guide exists

Hungary is one of the strongest engineering talent markets in Central Europe for US companies. Budapest has a dense developer community, Hungarian engineers have strong English and EU-trained STEM backgrounds, and rates often beat Western Europe. For a US company building a nearshore-to-EU team, Hungary is an easy place to start.

The compliance picture for Hungary changed in an unusual direction. After more than four decades, the United States terminated its income tax treaty with Hungary, so Hungary is no longer a treaty country. This sounds alarming, and many founders assume it means they now have to withhold tax on every payment to a Hungarian contractor. For the typical remote contractor, that is not the case. The reason is that the analysis for pure services performed in Hungary never depended on the treaty in the first place. We explain exactly why below, and where the termination does bite.

This guide covers what a US company needs to pay Hungarian contractors. We cover the US side (W-8BEN, the terminated treaty, the source-of-income rule), the Hungary side (the freelancer setup, AFA, social contributions), 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 Hungarian 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 Hungary, and is not a US person. The IRS Form W-8BEN page has the current form and instructions.

The W-8BEN matters just as much now as it did when a treaty existed. It is the document that supports treating the contractor’s Hungary-performed services as foreign source income with no withholding. The W-8BEN is valid for three calendar years after signature. If your contractor operates through a Hungarian company (a Kft. or similar), the form is Form W-8BEN-E, the entity equivalent, available on the IRS W-8BEN-E page. Use the free W-8BEN collection checklist to confirm you have the right form and fields.

The one change from a treaty country is Part II of the W-8BEN. Part II is where a contractor would normally claim treaty benefits, citing the treaty country. Because there is no US-Hungary treaty, the contractor leaves Part II blank. There is no treaty article to cite and no reduced rate to claim.

Step 2. Confirm the work is performed in Hungary

Under IRS source of income rules for personal services, services income is sourced to the place where the services are physically performed, regardless of where the contract was made, the place of payment, or the residence of the payer. If your Hungarian contractor does the work entirely from Budapest, Debrecen, Szeged, or anywhere else in Hungary, the income is foreign 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. This rule turns on where the work happens, not on whether a treaty exists.

For a typical pure services engagement where the Hungarian contractor never sets foot in the US, the result is: no withholding, no Form 1042-S, no 1099-NEC. The treaty termination does not change this analysis, because the analysis was never based on the treaty. This is the single most important point in the guide, and it is why the practical answer for most contractors is unchanged.

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 this is where the termination now bites, as the next section explains. Keep a simple onsite-days log.

Step 3. The treaty was terminated, so know what changed

The treaty status here is the headline, so be precise. There is no US-Hungary income tax treaty in force in 2026.

The United States gave notice of termination of the 1979 US-Hungary tax convention on 8 July 2022. Per the IRS Hungary tax treaty documents page, “termination was effective on January 8, 2023. However, as specified in the Convention, with respect to taxes withheld at source, the Convention ceased to have effect on January 1, 2024.” The same page notes that withholding agents may not accept treaty claims for payments made on or after that date. The US Treasury announcement of the notification of termination records the 8 July 2022 notice. Hungary now appears on the IRS list of income tax treaties A to Z with a “CAUTION Treaty Terminated” note rather than as a treaty in force.

What this means in plain terms: without a treaty, US source income paid to a Hungarian person can face the default 30 percent nonresident alien (NRA) withholding rate, with no treaty reduction available. There is no treaty article to lower the rate, and no Form 8233 treaty exemption to file, because Form 8233 claims treaty benefits and there is no treaty to claim under. For background on how treaties work in general, and what their absence means, see our income tax treaty glossary entry.

Here is the part that surprises founders, and it is the reason this is not a crisis for most relationships. The 30 percent NRA withholding applies to US source income. For a Hungarian contractor performing all of their work in Hungary, there is no US source income to begin with, because services are sourced to where they are performed. So the typical remote contractor faces no US withholding, treaty or not. The termination only changes the result for amounts that are US source, such as:

• Days a Hungarian contractor physically works inside the United States during an onsite visit. Those US source service days, which previously might have been sheltered by the independent personal services article of the treaty, are now exposed to 30 percent NRA withholding with no treaty relief.
• Certain US source royalties or other US source FDAP income, which now face 30 percent withholding instead of a reduced treaty rate.

If your engagement involves any of those, the cost of the termination is real and you should budget for it or restructure where the work happens. For a pure remote services engagement, the practical answer is unchanged. We are deliberately not overstating the impact, because the most common mistake is assuming termination means withholding on everything, when in fact it means withholding only on US source amounts that were never the bulk of a normal contractor relationship.

One related concept worth flagging for finance teams is permanent establishment. A contractor working from Hungary does not, on their own, create a US permanent establishment for your company, and a properly structured services engagement keeps that line clean. The risk runs the other way too: if your company starts directing a Hungarian contractor like an employee, with a fixed place of business and authority to bind the company, you can drift toward creating a Hungarian taxable presence. Keeping the relationship to deliverables, not management control, protects both sides.

Hungary side: what your contractor handles

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

The freelancer setup and the tax number

Most Hungarian freelancers working B2B with international clients operate either as a registered sole trader (egyeni vallalkozo) or through a small limited company (a Kft.). They register with the National Tax and Customs Administration of Hungary (NAV), receive a Hungarian tax number, and issue invoices for each engagement. Some sole traders historically used the simplified KATA flat-tax regime, though KATA was significantly narrowed in 2022 and now generally cannot be used for invoicing other businesses, so most contractors with corporate clients sit on the standard sole-trader or company regime.

You as the US payer do not need to know which form the contractor uses. You only need to ensure they can issue you a valid invoice with the correct VAT treatment.

AFA 27 percent and the place-of-supply rule

Hungary’s standard VAT is called AFA (altalanos forgalmi ado). The standard AFA rate is 27 percent, the highest in the European Union, with reduced rates of 18 percent and 5 percent for specific categories. You can confirm the current rate on the European Commission VAT rates page.

Hungarian AFA follows the EU VAT system, which means for B2B services the place of supply is generally where the customer is established. When your Hungarian contractor invoices your US company for services, the place of supply is the United States, outside the scope of EU VAT. The contractor issues an invoice marked as out of scope of Hungarian AFA, or as reverse charge, and you do not pay VAT on it.

If the contractor is below the Hungarian VAT registration threshold and is not voluntarily VAT-registered, the invoice is issued without AFA and the same out-of-scope treatment applies. The exact wording on the invoice depends on the contractor’s registration and activity classification, which their accountant confirms.

Hungarian social contributions and income tax

A Hungarian sole trader or company owner pays Hungarian personal income tax and social contributions on their own income, settled through NAV. These are the contractor’s own obligation on their own income. You as the US client do not pay them, do not contribute to them, and have no Hungarian social security reporting obligation.

There is no US-Hungary social security totalization agreement to coordinate cross-border coverage, which is consistent with the broader cooling in the tax relationship between the two countries. For a pure contractor engagement where the contractor pays their own Hungarian contributions, this has no effect on you.

The payment rail decision

There are a few real options for paying a Hungarian contractor from a US bank account. Hungary is in the EU but uses the Hungarian forint (HUF), not the euro, while still participating in SEPA for euro-denominated transfers.

For USD-denominated invoices, a provider that converts USD to HUF at a fair rate into the contractor’s Hungarian bank account is typically the cleanest. If the contractor holds a EUR account, a EUR transfer over SEPA lands quickly and cheaply, and the contractor converts to forint on their side. 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 Hungary

Hungary, like the rest of the EU, distinguishes a genuine independent contractor from disguised employment, and the labour and tax authorities can reclassify a relationship that walks and talks like employment. Hungarian rules look at substance over the label on the contract: whether the worker is subordinate, follows fixed hours, uses the engaging company’s premises and equipment, and is integrated into the company’s hierarchy. A reclassification can carry retroactive entitlement to employment protections and contributions.

The reclassification 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. 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 Hungarian 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. Leave Part II blank, because there is no US-Hungary treaty to cite.
3. Confirm the contractor is registered with NAV, has a Hungarian tax number, and can issue a valid invoice, and check whether they are VAT-registered since the invoice format differs slightly.
4. Pick a payment rail (a USD-to-HUF or SEPA-aware EUR provider) and onboard the contractor’s payout details (Hungarian IBAN).
5. Pay the invoice on schedule. Keep the W-8BEN, services agreement, invoice, and payment receipt together as a packet.
6. If the contractor ever works onsite in the US, log those US source days, because they now face 30 percent NRA withholding with no treaty relief.
7. 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 Romania, Czech, and Poland contractors.

When a platform pays for itself

A US founder paying one Hungarian contractor can do this manually. A US team paying five or more Hungarian contractors faces enough W-8BEN refreshes, AFA treatment confirmations, onsite-day tracking, 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 Hungary-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-HUF 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 Hungarian contractor relationship.

1. Is there a signed W-8BEN on file (with Part II left blank) and is it less than three years old?
2. Will all the work be performed in Hungary for the foreseeable future, with any US onsite days logged separately?
3. Are we paying through a rail that handles SEPA or USD-to-HUF cleanly and captures the invoice for every payment?

If yes to all three, you are in great shape on the US-Hungary stack even without a treaty, because pure Hungary-performed services were never subject to US withholding. The remaining work is misclassification hygiene over time and watching any US source days that now carry the full 30 percent NRA rate.
