Hungary isn’t exactly the first jurisdiction that comes to mind when you think “business freedom,” but I’ve seen worse. Much worse. If you’re looking at Hungary as a base for solo operations, the country offers a straightforward sole proprietorship structure called Egyéni vállalkozó. It’s accessible, reasonably regulated, and—here’s the kicker—comes with three distinct tax regimes that can either save you a fortune or trap you in bureaucratic hell if you pick wrong.
Let me walk you through what’s available, what it costs, and where the landmines are buried.
What Is an Egyéni Vállalkozó?
The Egyéni vállalkozó translates roughly to “Individual Entrepreneur” or sole proprietor. It’s the Hungarian equivalent of what most countries call a freelancer or self-employed person. You’re not incorporating. You’re just you, doing business under your own name (or a trade name if you register one).
No partners. No shareholders. Just your liability, your income, your taxes.
Registration is handled through the Hungarian tax authority (NAV) and local business registries. The process is relatively painless compared to some of the Eastern European nightmares I’ve audited. You’ll need a local address, tax number, and basic documentation. If you’re an EU citizen, it’s even easier. Non-EU? Expect more friction, as always.
The Three Tax Regimes: Choose Wisely
Here’s where Hungary gets interesting. Most countries give you one or maybe two ways to tax a sole proprietorship. Hungary gives you three, and each has radically different economics.
1. KATA: The Flat-Fee Gamble
KATA stands for Kisadózók Tételes Adója, or “Simplified Tax for Small Taxpayers.” It’s a fixed monthly payment of HUF 50,000 (approximately $135 USD at 2026 rates). That’s it. No percentage of revenue. No profit calculations. Just a flat fee.
Sounds great, right?
It is—if you qualify. And here’s the problem: as of recent reforms, KATA is restricted to full-time entrepreneurs serving only private individuals (B2C). If you’re doing any B2B work, KATA is off the table. The government got tired of companies disguising employees as KATA contractors to dodge payroll taxes. So they nuked the loophole.
If you’re a fitness coach, photographer, or consultant working exclusively with end consumers, KATA is a steal. You pay HUF 50,000 monthly, and that covers your personal income tax and social contributions. No bookkeeping nightmares. No quarterly estimates.
But the moment you invoice a company? You’re out. And the penalties for misclassification are not polite.
2. Flat-Rate Taxation (Átalányadó): The Middle Ground
If KATA doesn’t fit, the next option is flat-rate taxation, or Átalányadó. This regime calculates your taxable income by applying a cost allowance to your revenue. You don’t need to track every expense—the state assumes a percentage of your revenue is costs.
The cost allowance varies by industry:
- 40% for most service businesses
- 80% for certain activities (e.g., some professional services)
- 90% for retail and resale
After applying the allowance, you pay:
- 15% personal income tax (PIT)
- 18.5% social security contribution
- 13% social contribution tax
Total effective rate? Around 46.5% on your calculated taxable income. That’s brutal if your actual profit margins are thin, but reasonable if you’re pulling high margins with low real costs.
Example: You earn HUF 10,000,000 ($27,000 USD) in revenue. If you get the 40% cost allowance, your taxable base is HUF 6,000,000 ($16,200 USD). Your combined tax burden is roughly HUF 2,790,000 ($7,540 USD). Not terrible. Not great.
This regime works if you’re doing B2B work and can’t use KATA, but you don’t want the administrative overhead of full bookkeeping.
3. Entrepreneurial Income Tax (Standard): The Full Monty
The third option is the standard regime. You track all income and expenses, calculate actual profit, and pay:
- 9% income tax on profit
- 15% dividend tax on withdrawals
- Social contributions (varies based on income)
This is the most flexible option. If you have significant deductible expenses—equipment, travel, subcontractors—you can reduce your taxable base considerably. But you need proper bookkeeping. And you need to stomach the idea that Hungary will tax you once on profit and again on distributions.
It’s the regime for higher earners who want optimization and are willing to pay an accountant to make it work.
The Turnover Limit
Hungary caps sole proprietorship revenue at HUF 18,000,000 annually (roughly $48,600 USD). Cross that threshold, and you’re forced to incorporate or restructure.
This is not a soft limit. It’s a hard ceiling. If you’re growing fast, plan your exit from sole proprietorship status before you hit it. The last thing you want is to breach the cap mid-year and scramble to set up a Kft (Hungarian LLC) while the tax authority breathes down your neck.
My Take
Hungary’s sole proprietorship system is functional. It’s not a tax haven, but it’s not a dystopian bureaucracy either. If you’re small, B2C, and under the turnover limit, KATA is one of the better flat-fee regimes in Europe. If you’re B2B, you’ll pay closer to Western European rates under the flat-rate or standard regimes—but at least you have options.
The real risk is picking the wrong regime. KATA looks seductive until you realize one B2B invoice disqualifies you. The standard regime looks complex until you realize it’s the only way to properly deduct costs if you’re running a capital-intensive operation.
Do your math. Model your revenue, your client mix, and your cost structure before you register. And if you’re non-EU, factor in the residency and immigration friction—Hungary is not hostile, but it’s not rolling out the red carpet either.
I update my intel on Hungary regularly. If you’ve got recent experience with NAV or official documentation that contradicts what I’ve outlined here, let me know. I’m always auditing these jurisdictions.
