Starting a business in Czechia
The živnost licence, the 60/40 expense fiction, and a flat-tax regime that folds everything into one monthly payment.
Checked against the sources on 2026-08-30
Before anything else
Czech self-employment runs on the živnostenské oprávnění - the trade licence. One visit (or data-box filing) at any trade office registers the licence and, through the single registration form, the tax office, social security and health insurance at once. Most services and IT fall under the free trade ("volná živnost"), which needs no qualification and covers eighty listed activities under one licence.
The tax landscape is friendlier than the paperwork: OSVČ can deduct flat percentage expenses without receipts - 60% of revenue for trades, 40% for independent professions - or opt into paušální daň, a single monthly payment (from roughly CZK 8,700 in the lowest band) that settles income tax, social and health in one transfer with no annual return at all.
The legal shell
OSVČ or s.r.o.?
OSVČ (self-employed with a živnost)
The default. The flat expense percentages make modest service businesses nearly bookkeeping-free.
CZK 1,000 licence fee, once.
Minimum social and health advances are due monthly from the start (reduced in the first years), profit or not.
s.r.o.
Liability or partners. Minimum capital is CZK 1.
Notary and registrations, commonly CZK 8,000-15,000 all-in.
Real accounting from day one, and profit extraction is taxed twice (19% corporate + 15% dividend withholding).
The sequence
File the single registration at a trade office
Where: Any živnostenský úřad, or via the JRF form and a data boxCost: CZK 1,000Takes: The licence is usually active within days
Pick the free trade and tick the activity fields you might ever use - they cost nothing extra. The same form registers you for income tax and starts social (ČSSZ) and health insurance advances.
Consider paušální daň before the year starts
Where: The tax office, by the 10th of January (or on registration)
One monthly payment, no tax return, no insurance overviews - available up to CZK 2,000,000 revenue, in three bands. The catch: no expense deduction, no tax credits, and VAT registration disqualifies you.
Watch the VAT line
Registration becomes compulsory at CZK 2,000,000 of turnover in a calendar year. B2B services to other EU countries trigger the lighter "identified person" status instead - a common surprise for freelancers invoicing abroad.

This is a map, not legal or tax advice - and an honest one about how it was drawn: the Germany guide was written by a person who walked the route; most other countries were drafted with AI against the official sources and have not yet been walked by someone who did it. Laws change. Every guide carries the date it was last checked and the sources to check it yourself - and if you have been through one of these routes, your corrections are exactly what this handbook wants.
