Some numbers first. In the last five years, the number of self employed people in Czechia grew by more than 127,000. By the end of 2025, there were over 1.17 million OSVČ in the country. That is a lot of people figuring out social security on their own.
So on July 27, 2026, the Czech Social Security Administration, ČSSZ, published a new official guide aimed at people just starting self employment. It is called Průvodce sociálním zabezpečením pro OSVČ, and it walks through the basics of pension and sickness insurance for freelancers.
Why this matters
Honestly, this is a good sign. It means the state finally noticed that a huge and growing chunk of the workforce needs clearer information, not just a wall of legal text. The guide covers things like when your insurance obligations start, how to calculate your advance payments, how the annual income and expense overview works, how the flat tax regime interacts with social security, and how sickness insurance works if you choose to opt in.
If you are Czech, work in Czech, and only deal with Czech authorities, this guide is a genuinely solid starting point.
Where it falls short for you as an expat
Here is the catch. The guide is written in Czech, for a Czech audience, assuming a Czech context. It does not touch the situations that actually apply to foreigners, like different document requirements when you register your trade license as a non-EU national, which health insurance rules apply to you based on your citizenship and residence status, how cross-border invoicing changes your VAT obligations, or the fact that you need to be a Czech tax resident to even qualify for the flat tax regime.
Those are not small details. They are usually the exact things that turn into expensive mistakes six months down the road.
This is precisely why our Freelancer Starter Kit exists
Everything ČSSZ just explained in their new guide, we already cover in the Czech Freelancer Starter Kit, in plain English, written specifically for people navigating this system as foreigners. Registration, deadlines, social security, sickness insurance, the flat tax decision, all of it, but built around the questions expats actually ask us in real consultations.
You can find the Kit here.
