Common Mistakes Foreign Entrepreneurs Make in Hungary

We work with foreign founders every day, and certain mistakes come up again and again. Here are the ones worth avoiding.

1. Choosing the wrong structure from the start

Picking a sole proprietorship for convenience without considering liability exposure — or setting up a Kft. before it's actually needed — both create avoidable headaches down the line.

2. Missing the real-time invoice reporting requirement

Many founders coming from countries without this requirement simply don't realize invoices must be reported to NAV electronically, often in real time. Manual invoicing without compliant software is a common source of penalties.

3. Underestimating employer costs

New employers frequently budget only for gross salary, forgetting that employer-side contributions add a meaningful amount on top — this can catch a growing business off guard.

A good habit: whenever you're planning a hire or a major expense, run the numbers with total cost in mind, not just the headline figure.

4. Missing filing deadlines

Hungary has multiple recurring deadlines — monthly payroll filings, VAT returns, annual tax returns. Missing even one can trigger penalties that compound over time.

5. Assuming home-country rules apply

Rules around invoicing, VAT, contracts, and employment differ meaningfully from country to country. What worked in your home market often doesn't translate directly to Hungary.

The easiest way to avoid these

A short conversation early on can save significant time and money later. That's exactly what we're here for — reach out before a small oversight becomes a bigger problem.
