iGaming & Casino Affiliate Tax: The Bulgaria Base

Q: Do I charge VAT on affiliate commission to a gambling operator?

Gambling and betting are VAT-exempt under Article 135(1)(i) of the EU VAT Directive, but that exemption is for the operator's gaming supply — not for your marketing service. Your affiliate service is a taxable B2B supply. Under Article 44 of the VAT Directive and Article 21(2) of the Bulgarian VAT Act, the place of supply is where the operator is established: if it is in another EU state the operator accounts for the VAT under the reverse charge, and if it is outside the EU the supply is generally outside EU VAT scope. Because you are supplying cross-border B2B services, you may need a Bulgarian VAT number even below the EUR 51,130 registration threshold, so this needs checking for your exact operator mix.

Q: How do I become tax resident in Bulgaria as an affiliate?

Under Article 4 of the Personal Income Tax Act you are Bulgarian tax resident if you spend more than 183 days here in a 12-month period, or if your centre of vital interests — home, family, economic life — is in Bulgaria. For a location-independent affiliate, building a genuine centre of vital interests here is usually the substance that matters, and if you use a company, running it from Bulgaria keeps its place of effective management, and therefore its tax residence, in the country too.

If you send players to casinos and sportsbooks for a cut of the action, your commission is business income — not tax-free gambling winnings. That one sentence corrects the most expensive misunderstanding in the affiliate sector. Revenue share, CPA and hybrid deals feel like they ride the same exemption that lets a winning player keep their jackpot untaxed. They do not. Your commission is payment for a marketing and player-acquisition service, taxed by where you are resident and by the place of management of any company you use. On top of that sit two problems most affiliates underestimate: banking, because iGaming is a high-risk category that processors and banks actively de-risk, and VAT, because gambling is exempt but your marketing service is not. This guide walks through all three — the winnings myth, the banking problem and the VAT position — and how a genuine Bulgarian base (10% flat, ~7.5% as a freelancer, 15% via a company) fits. For general affiliate networks like CJ, Awin or Amazon, see our affiliate marketing tax guide; this piece is specifically about gambling affiliates.

Running a casino or betting affiliate business? The costly mistake is assuming commission is tax-free like a player's winnings, then discovering in an audit — or when a bank closes your account — that it is fully taxable service income with a VAT dimension attached. Get the classification, the banking and the VAT right at the start and the whole thing is defensible.

The Myth: "My Commission Is Tax-Free Like a Player's Winnings"

Start with the mistake that costs affiliates the most, because everything else follows from correcting it. A player who wins on a licensed casino or sportsbook keeps that win tax-free in many countries. Affiliates see that, assume the same treatment flows to them, and quietly decide their commission is untaxed too. It is not — and the reasoning is simple.

The winnings exemption is written for the winner of the bet. In Bulgaria, чл. 13, ал. 1, т. 20 ЗДДФЛ (Article 13(1)(20) of the Personal Income Tax Act) makes cash and in-kind winnings from participation in licensed games of chance — organised under the Bulgarian Gambling Act, or under the law of another EU/EEA state — non-taxable for the person who wins them. That is the player. You are not the player. You never place the bet, you never take the gaming risk, and you are not paid because a wager came in. You are paid because you delivered a marketing and player-acquisition service to the operator, and revenue share, CPA and hybrid are just different pricing models for that same service.

So your commission is ordinary business and service income, taxed by your tax residence — exactly like any other performance-marketing fee. Whether it is called revenue share off a player's lifetime losses, a fixed CPA per depositing player, or a hybrid of both makes no difference to the character of the income. It is a service fee, and it is taxable.

The audit trap: an affiliate who has treated years of commission as "tax-free winnings" is not just facing tax — they are facing tax on gross, plus interest and penalties, on income they thought was clean, with no expense position built because nothing was ever declared. The fix is cheap before you scale and painful afterwards. Classify the income correctly from day one.

If you are the person actually gambling for a living rather than the affiliate sending players, this is the wrong article for you — the tax treatment is completely different. See our companion guide for the professional poker and gambling player instead.

How iGaming Affiliate Tax Actually Works in Bulgaria

Once the income is correctly classified as business income, Bulgaria taxes it the same way it taxes any online service business — and it is one of the lowest bases in the EU:

~7.5% effective as a freelancer — a registered freelancer pays the 10% flat rate after a 25% statutory expense allowance under чл. 29 ЗДДФЛ, giving roughly 7.5% effective income tax (social security is separate). See our freelancer tax rate guide for the mechanics.
15% combined through an EOOD — 10% corporate income tax plus 5% on dividends when you distribute, if you run the affiliate business through a Bulgarian company. Our company vs freelancer comparison shows where the line falls, and for a high-risk activity like iGaming the company route often wins on bankability alone.
No wealth tax and no exit tax — the position you build is not quietly taxed year after year, and leaving later does not trigger a departure charge.

There is no special gambling-affiliate tax. Your commission is taxed like any marketing or consulting fee, so the whole business follows your residence. Move your genuine tax residence to Bulgaria and the commission is taxed at these rates, wherever the operators and players sit.

The Banking Problem — Why Casino Affiliate Structuring Is Half the Value

This is the part of casino affiliate life in Bulgaria and everywhere else that catches operators off guard, and it is where good structuring earns its keep. iGaming sits in a high-risk merchant category. Banks and payment processors carry heavier anti-money-laundering, chargeback and reputational exposure on gambling-linked money, so many of them de-risk: they decline the account, freeze it, or close it — sometimes with little notice and sometimes mid-cycle. Chargeback rates in gambling run far above ordinary e-commerce, the sector spans a patchwork of licensing regimes, and compliance teams flag anything with a gambling scent. An affiliate is a step removed from the operator, but the association is enough to trigger the same scrutiny.

The practical consequence is that a clean structure is not cosmetic — it is what keeps you banked. The affiliate who invoices licensed operators through a properly documented EU company, with honest activity descriptions, clear contracts and transparent flows, is a materially easier account to open and to keep than someone running large gambling-linked receipts through a personal account with a vague description. The elements that matter:

A real EU company — an EOOD gives the business a legal identity separate from you, which banks and processors underwrite far more comfortably than a private individual receiving gambling-linked funds.
Clean contracts and invoicing — written affiliate agreements with each licensed operator, and invoices that describe a marketing service, so the money has a documented, legitimate source.
Honest activity codes and descriptions — the company's registered activity and its account application should reflect what it does; a mismatch is exactly what triggers de-risking later.
Transparent, explicable flows — being able to show where money comes from and why is the single best defence against a freeze or a closure.

None of this makes iGaming a low-risk category in a bank's eyes — nothing does. But it moves you from the "close on sight" pile to the "documented, licensed-counterparty, bankable business" pile, which is the difference between a stable operation and one that loses its processor at the worst moment. Because Bulgarian banking has its own onboarding hurdles for foreigners, it pays to read our note on why Bulgarian banks reject foreigners before you apply.

Why we treat banking as part of the tax job: for most affiliates the structuring that makes you bankable and the structuring that makes you tax-efficient are the same structuring — a genuine Bulgarian EOOD with substance, clean contracts and correct VAT handling. Solve them together and you get a business that is both low-taxed and actually able to receive its money.

VAT on Affiliate Marketing Services — the Piece Nobody Explains

Here is the counter-intuitive part. Gambling and betting are VAT-exempt — under Art. 135(1)(i) of the EU VAT Directive (2006/112/EC) the operator's gaming supply carries no VAT. Affiliates see "gambling is VAT-exempt" and assume it covers them too. It does not. The exemption is for the operator's gaming activity, not for the marketing service you sell to the operator. Your affiliate service is a normal taxable B2B supply, and it has its own place-of-supply rules.

For business-to-business services the place of supply is where the customer — the operator — is established, under Art. 44 of the VAT Directive and чл. 21, ал. 2 ЗДДС. What that means in practice:

Operator in another EU state — the place of supply is that state, and the operator accounts for the VAT itself under the reverse charge. You invoice without Bulgarian VAT but with the correct reverse-charge reference, and you report it as an intra-EU service.
Operator outside the EU — the supply is generally outside the scope of EU VAT, so no EU VAT applies. This is the common case with operators licensed in offshore or non-EU jurisdictions, but it needs checking operator by operator, because establishment and fixed-establishment questions can move the answer.
Operator in Bulgaria — a domestic taxable supply on which Bulgarian VAT applies in the normal way.

The registration angle is where affiliates trip. Bulgaria's mandatory VAT registration threshold is EUR 51,130 of taxable turnover under чл. 96, ал. 1 ЗДДС — but that domestic threshold is not the whole story for cross-border services. Supplying B2B services to operators in other EU states can require a Bulgarian VAT number regardless of turnover, so you may need to register even while small. Because your operator mix — EU, non-EU, and the odd Bulgarian counterparty — decides the whole picture, this is the one area to confirm precisely rather than assume; our Bulgaria VAT registration guide covers the mechanics and the thresholds.

The honest caveat: VAT on cross-border affiliate services is genuinely fact-specific — the operator's exact place of establishment, whether it has an EU fixed establishment, and your own registration status all move the outcome. The framework above is the right map, but the registration and invoicing rules for your specific set of operators should be pinned down before you issue invoices, not after.

How Affiliate Commission Is Taxed — Personal vs EOOD, and the Winnings Myth

Gambling affiliate commission in Bulgaria — the routes, and what it is not — as of 2026
Treatment	Effective tax	What it is
"Tax-free gambling winnings"	N/A — wrong	The myth. The чл. 13(1)(20) exemption is the player's, not the affiliate's — never available to commission
Freelancer (registered)	~7.5% effective	10% flat after 25% statutory expense allowance (чл. 29 ЗДДФЛ); social security separate
EOOD company	15% combined	10% corporate (ЗКПО) + 5% on dividends; best bankability for high-risk iGaming
Commission paid in crypto	~9% on later gain	Income on receipt at market value; disposal gain taxed on net profit after 10% (чл. 33(3) ЗДДФЛ)
Your VAT on the service	Reverse charge / out of scope	EU operator accounts for VAT; non-EU operator generally outside EU scope (чл. 21(2) ЗДДС)
Wealth / exit tax	None	Bulgaria levies neither — the base stays clean over time

The top row is the point of the whole article: the treatment affiliates most often reach for is the one that does not exist for them. Everything below it is the real, low-tax reality once the income is classified honestly.

If an Operator Pays You in Crypto

Some operators, especially crypto-native casinos and sportsbooks, settle affiliate commission in stablecoins or tokens. That does not change the analysis — it just adds a step. Receiving crypto as payment for your service is business income valued at its market price on the day you receive it. When you later sell or convert it, that is a separate taxable event: under чл. 33, ал. 3 ЗДДФЛ the gain on crypto and other financial assets is taxed on the net annual profit after a 10% expense allowance — roughly 9% effective — with the character confirmed by the 2026 amendment that expressly brings crypto into that provision. The practical takeaway is that crypto commission is neither invisible nor tax-free; it simply carries a valuation and record-keeping obligation you have to meet. For the full picture see our Bulgaria crypto taxation guide.

Doing It Properly — Residence and Substance, Not a Mailbox

The low rates belong to a genuine resident and a genuine company. Both turn on real facts, not paperwork:

Genuine Bulgarian residence — under чл. 4 ЗДДФЛ you are Bulgarian tax resident if you spend more than 183 days here in a 12-month period, or if your centre of vital interests is in Bulgaria. For a location-independent affiliate, building a real centre of vital interests here — the 183-day and centre-of-interests tests — is usually the substance that matters.
A company with real substance — if you use an EOOD, its tax residence depends on its place of effective management under чл. 3 ЗКПО. Run it from Bulgaria — an office, a director exercising authority here, an active bank account — so its management, and therefore its residence, is genuinely Bulgarian. Our note on EOOD substance requirements sets out what "real" looks like.
Documented flows — contracts with licensed operators, clean invoicing and filed returns, so the position is evidenced if the authorities or a bank ever ask.

These rates only protect you if the residence and the company behind them are real. If you are still weighing where to base yourself at all, our country-selection framework is the companion piece.

A Word on Advertising Law — Separate From Tax

One honest caveat that has nothing to do with tax but matters to your business: gambling advertising is restricted or licensed in many countries, and the rules vary sharply by market. Some jurisdictions ban gambling promotion outright, some allow it only for locally licensed operators, and many limit the channels, the audiences and the messaging you can use. Where you can lawfully promote, and to whom, is an advertising-law and compliance question that sits alongside your tax structure, not inside it. A clean Bulgarian base gives you a low-tax, bankable home for the income; it does not by itself make promotion lawful in every market you send players from. Treat the two as separate workstreams — get the tax and banking right here, and check the advertising rules for each market you target.

Common questions before booking:

Is my commission really taxable? Yes — it is service income, not the player's tax-free winnings. There is no version of revenue share or CPA that rides the gambling exemption.

Freelancer or EOOD? Freelancer at ~7.5% is simplest for a solo affiliate; an EOOD at 15% combined usually wins as you scale, and banks a high-risk activity far more credibly.

Do I charge VAT to operators? Your service is taxable, but for EU operators it is reverse-charged and for non-EU operators it is generally outside EU scope — confirm per operator.

What about crypto commission? Taxable as income on receipt, with a ~9% charge on any later gain under чл. 33(3) ЗДДФЛ. Not invisible, not tax-free.

When Bulgaria Is Not the Right Base

You will not actually relocate. The 10% belongs to a genuine resident. A paper move with your life still elsewhere creates risk without the saving.
You are a US citizen. US citizens are taxed on worldwide income regardless of residence — Bulgaria still helps, but the US overlay needs separate advice.
Your model depends on promoting where it is unlawful. If the business only works by advertising gambling into markets that prohibit it, the problem is the model and its compliance, not the tax base.
You want to pay nothing anywhere. Bulgaria is low and EU-compliant, not zero. A plan built on paying nothing is an exposure, not a plan.

Frequently Asked Questions

Is my casino or betting affiliate commission tax-free gambling winnings? +

No. This is the single most expensive myth in the sector. The gambling-winnings exemption applies to the player who wins on a licensed game — in Bulgaria, cash and in-kind winnings from licensed games of chance are non-taxable for the winner under чл. 13, ал. 1, т. 20 ЗДДФЛ (Article 13(1)(20) of the Personal Income Tax Act). Your affiliate commission is something completely different: it is payment for a marketing and player-acquisition service, so it is ordinary business and service income taxed by your tax residence. Treating revenue share or CPA as tax-free winnings is a mistake that catches affiliates in audit.

How is iGaming affiliate income taxed in Bulgaria? +

As ordinary business income. As a Bulgarian tax resident you can run it as a registered freelancer at the 10% flat rate after a 25% statutory expense allowance — roughly 7.5% effective under чл. 29 ЗДДФЛ — or through an EOOD company at 15% combined (10% corporate under ЗКПО plus 5% on dividends). There is no special gambling-affiliate tax; commission is taxed like any other service income, and Bulgaria has no wealth tax and no exit tax.

Why do banks and processors keep closing iGaming affiliate accounts? +

Because iGaming sits in a high-risk merchant category. Banks and payment processors face heavier anti-money-laundering, chargeback and reputational exposure on gambling-linked flows, so many de-risk — declining, freezing or closing accounts, sometimes with little notice. An affiliate is a step removed from the operator, but the gambling association still triggers scrutiny. A clean, properly documented EU company with clear contracts and invoicing to licensed operators, honest activity descriptions and transparent flows is materially easier to bank and to keep banked than an opaque personal setup.

Do I charge VAT on affiliate commission to a gambling operator? +

Gambling and betting are VAT-exempt under Art. 135(1)(i) of the EU VAT Directive, but that exemption is for the operator's gaming supply — not for your marketing service. Your affiliate service is a taxable B2B supply. Under Art. 44 of the VAT Directive and чл. 21, ал. 2 ЗДДС, the place of supply is where the operator is established: if it is in another EU state the operator accounts for the VAT under the reverse charge, and if it is outside the EU the supply is generally outside EU VAT scope. Because you supply cross-border B2B services, you may need a Bulgarian VAT number even below the EUR 51,130 threshold under чл. 96, ал. 1 ЗДДС, so this needs checking for your exact operator mix.

Freelancer or EOOD for a gambling affiliate business? +

A solo affiliate often starts as a registered freelancer at roughly 7.5% effective — simple and cheap. As the business scales — larger revenue share, multiple operators, retained profit, staff or media spend, or a portfolio of sites worth protecting — an EOOD at 15% combined usually wins, because it separates the business from you personally, banks more credibly for a high-risk activity, retains profit at 10% and taxes distributions at 5%. Many affiliates begin as freelancers and convert to an EOOD as commission grows.

What if a casino operator pays my commission in crypto? +

It is still taxable. Receiving crypto as payment for your affiliate service is business income valued at the market price on receipt, and a later disposal or conversion is a separate taxable event. Under чл. 33, ал. 3 ЗДДФЛ, gains on crypto and other financial assets are taxed on the net annual profit after a 10% expense allowance — roughly 9% effective. Crypto payment does not make the income invisible or tax-free; it simply adds a valuation and record-keeping layer that has to be handled properly.

How do I become tax resident in Bulgaria as an affiliate? +

Under чл. 4 ЗДДФЛ you are Bulgarian tax resident if you spend more than 183 days here in a 12-month period, or if your centre of vital interests — home, family, economic life — is in Bulgaria. For a location-independent affiliate, building a genuine centre of vital interests here is usually the substance that matters, and if you use a company, running it from Bulgaria keeps its place of effective management under чл. 3 ЗКПО, and therefore its tax residence, in the country too.

Is promoting gambling even legal where my players are? +

That is a separate question from tax, and it matters. Gambling advertising is restricted or licensed in many countries, and the rules differ sharply by market — some ban it, some require the operator to be locally licensed, some limit channels and messaging. Where you can lawfully promote, and to whom, is an advertising-law and compliance question that sits alongside the tax structure, not inside it. A clean Bulgarian base handles the tax; it does not by itself make promotion lawful in every jurisdiction you target.
