No more KATA. No more guessing your tax.

The switch isn't hard, it's just different from KATA
Which tax regime should I pick now?
Whether átalányadó or vállalkozói szja works out better depends on your actual revenue and costs, not a one-size-fits-all rule.
I never had to track costs before
KATA's flat monthly fee meant the ratio of revenue to cost never mattered. Under átalányadó or vállalkozói szja it does, and it's the part most people underestimate at first.
What is this szocho? KATA never had that
The flat monthly KATA tax covered everything. Under átalányadó or vállalkozói szja, social contribution tax is due separately, generally on at least the minimum wage, even in a month you withdrew less.
Hungarian tax, tracked as you go
Your átalányadó revenue ceiling, tax-free allowance, and VAT exemption threshold all show up on the Dashboard at once, with a projection for when you'd cross any of them.
Hungarian Tax & NAV Integration →Income & expenses
Log your entries where you used to just pay a flat monthly fee, so the app, not you, works out what you actually owe.
Income & Expenses →Receipt scanning
Photograph a receipt and the app fills in the expense details for you, using on-device AI, with nothing sent to the cloud.
Receipt Scanning →Insights
A running tax estimate, broken down by quarter, so what you owe is never a surprise now that it tracks your actual revenue instead of a flat KATA fee.
Insights →Built for the rules that actually apply to you
This doesn't replace reading the specifics: the exact rules, with the exceptions, are in the full guides.
Since the 2022 reform, KATA can generally only be chosen by a main-occupation sole proprietor who works exclusively for private individuals, not for businesses, organizations, or foreign payers.
Outside KATA, social contribution tax must be established and paid separately, generally on at least the minimum wage for a main-occupation proprietor, even in a month you withdrew less.
Whether átalányadó or vállalkozói szja works out better depends on your actual cost ratio, so it's worth comparing the two using your own numbers.
Quick answers
