Public or commercial health insurance?
Some foreigners are not in the public health insurance system and have commercial insurance instead. This decides whether you pay health insurance advances as OSVČ. The app asks about it right at the start.

For foreigners
Running a business in Czechia, but Czech isn't your first language?
We build the app mainly for people who are still getting to know the Czech system. We use plain words and point out what works differently for foreigners.
The flat-tax regime is not for everyone
The flat tax (paušální daň) has conditions that foreigners often don't meet, such as taking part in public health insurance. The app tells you whether it's an option for you.
Czech terms explained in plain words
Záloha, přehled, paušální daň, DPH… Every term comes with an explanation and the Czech name you'll see at the offices.
When you're stuck, ask
The AI assistant answers right away, a person from support usually within 24 hours on business days.

FAQ
What people ask
Is this tax advice?
No. The app makes informational calculations and gives general information. You are responsible for filing your returns and statements correctly. For your specific situation, talk to a tax advisor.
Who is OSVČ Asistent for?
For the self-employed (OSVČ) in Czechia who want an overview of taxes and insurance without spreadsheets. Especially for new entrepreneurs and foreigners. It works for main and secondary self-employment.
Do I need an account?
You can try the calculators and the AI assistant, with a limited number of questions, without an account. The overview, income and expense records and support need an account.
Is my data safe?
The connection is encrypted, passwords are stored only as a hash, and we don't use or sell your data for advertising. You can export your data or delete your account yourself in Settings.
What happens after the beta?
After the beta the price is CZK 89 a month or CZK 839 a year, and beta users keep a discount. Nothing is charged automatically, you would have to confirm a payment yourself. Your data stays.
Which languages does the app support?
Czech, English, Ukrainian and Russian. In every language we keep the Czech official terms (zálohy, přehled, paušální daň…) with an explanation, because those are the words you will meet at the offices. The Czech versions of the legal documents are binding.
How does support work?
Write to us right in the app, in the Support section (after you register). A person answers, usually within 24 hours on business days. We help with the app and with general information; it is not tax advice.
Where do the rules and rates come from?
From the laws in force and official sources: the Financial Administration, ČSSZ and the health insurers. If you find a mistake, please tell us via Feedback.
