Can I work cash-in-hand in Czechia?
No — and you risk more than the employer admits. Performing illegal work is an offence on your side too: fines up to CZK 100,000. On top you lose everything that makes employment employment: sick pay, accident insurance, pension periods, unemployment benefits — and an injury on an undeclared site leaves you unprotected. Fake self-employment (švarcsystém) is judged the same: invoicing as a freelancer while really working as an employee (one client, their tools, their hours) — worker fines up to 100,000, company fines in the millions. Labour inspectorates target construction, gastronomy and warehouses, with higher rates and shared data since 2024. The legal light-weight route exists: DPP agreements with minimal paperwork.
📋 The rules
- Illegal work: the worker's offence — fines to CZK 100,000
- No contract = no sick pay, accident cover, pension periods or benefits
- Fake self-employment: same sanctions, millions for the company
- Inspectorate checks: construction, gastro, warehouses — also on tips
- Legal alternative: DPP/DPČ agreements with minimal admin
🔓 Exceptions
- Neighbourly help and occasional one-off favours (no dependent work) — see the 50k occasional-income rule
- Unpaid family help in the household/business: outside illegal work
⚠️ Penalties & fines
Worker: fines up to CZK 100,000. Employer: CZK 50,000–10,000,000 for enabling illegal work plus levy reassessments. Foreigners without permits additionally risk expulsion.

❓ Frequently asked
What do I risk as an undeclared casual worker?
Fines up to CZK 100,000, zero protection after an injury, and unpaid wages you can't enforce through the standard route.
How do I recognise fake self-employment?
You invoice a single "client", on their premises, with their tools, on their schedule — that's dependent work, not business.
Part of my pay comes cash-in-hand. Problem?
Yes — off-book pay cuts your insurance and pension base, and in a dispute only the paper part is provable.
How do I do a one-off gig legally?
Occasional income up to CZK 50,000 a year, or a DPP agreement — both with minimal admin.
