We don't just do the books.
We make them clear.
Accounting and tax compliance for people who run a business in Hungary — but don't run it in Hungarian.
Sole proprietors, freelancers and companies. Everything online, everything explained.
Cortaxo is an online accounting firm in Hungary for freelancers, sole proprietors and small companies — most of them not Hungarian. We handle the filings, the deadlines and the tax office, and we explain what is happening in plain English.
For many of our clients, getting this right matters for more than money. We know that, and we treat it that way.
Chosen by entrepreneurs and freelancers building businesses in Hungary — most of them from somewhere else.
The rules exist.
The deadlines are real.
But nobody explains them to you.
Most foreign business owners in Hungary don't struggle with running their business. They struggle with a system written in a language they don't read.
→ You don't have a business problem — you have a translation problem.
Transparency
- You don't know how much you keep
- You pay, but you don't understand why
Predictability
- You don't know what's coming next month
- Surprise payments, unexpected charges
Peace of mind
- You don't know if you've missed something
- Rules you never saw, in a language you don't read
We don't just do the books.
We interpret your operations.
You see what you pay, when, why — and how much is left. We don't just record what happened. We monitor your operations.

Laci Dudás
FounderWhy I created
Cortaxo.
I spent over 10 years in corporate and consulting environments, where it was natural that decisions were backed by systems. When I started working with entrepreneurs, I saw a gap — and with foreign entrepreneurs in Hungary, a second one on top of it.
Hungarian tax rules are not unusually complicated. They are unusually inaccessible. The deadlines are real, the penalties are real, and almost none of it is written in a language my clients read.
On top of that, it is hard to reach your accountant, answers come late, or they are not practical. If you also cannot read the letter that just arrived from the tax office, that stops being an inconvenience.
"For me, finance isn't a separate field — it's the language through which a business's operations can be understood. My job is to make sure that language isn't a second barrier."
Cortaxo is the operational form of this thinking. Understand what is happening — then decide, in a language you actually think in.
What do those say

„It is hard enough to be an entrepreneur. Now try doing it in a foreign country with a very difficult language. Finding Laci has been incredibly reassuring throughout this process. He and his team are not only extremely available and kind, but they also make everything smoother and easier to understand. 100% recommended if you feel lost with your taxes in Hungary.”
„They are excellent accountants. They helped me pay taxes on some stock I received and they were really helpful and professional. I had problems finding accountants in Hungary but they have been more than I could expect for. I am incredibly happy and I will surely request their help in the future.”
„Professional, fast, reliable. Laci perfectly understands modern, online businesses and was extremely helpful in preparing the company formation. Highly recommended!”
„I'm so happy with their service! László Dudás filed my tax return, fixed my account, and made everything simple and stress-free. Communication was excellent — He speaks great English and are super easy to work with. I highly recommend them to everyone looking for reliable tax help!”
