Can I work cash-in-hand in Czechia?
No — and you risk more than the employer tells you. Performing illegal work is an offence on your side too, with fines up to CZK 100,000. On top you lose everything that makes employment employment: sick pay, accident insurance, pension periods and unemployment benefits — and an injury on an undeclared site leaves you with no cover and no claim. Fake self-employment (švarcsystém) is judged the same: you invoice as a freelancer while really being an employee (one client, their tools, their working hours) — worker fines up to CZK 100,000, company fines up to 10 million. Labour inspectorates target construction, gastro and warehouses. A light legal route exists: a DPP agreement or occasional income up to CZK 50,000 a year.
📋 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
- DPP and DPČ agreements: the legal alternative with minimal admin instead of working with no contract
⚠️ Penalties & fines
The worker: fines up to CZK 100,000 — illegal work is not only the company's problem. The employer: from CZK 50,000 up to CZK 10,000,000 for enabling illegal work, plus retroactive levy reassessments. Foreigners without a work permit additionally risk expulsion. The real cost, though, is invisible: with no contract you have no sick pay, no accident insurance and no pension periods, so an injury comes out of your own pocket and the years worked vanish from your pension. Unpaid wages are also hard to enforce — you hold no proof that you ever worked, or for how much.

❓ Frequently asked
What do I risk as an undeclared casual worker?
Fines up to CZK 100,000, zero protection if you are injured, and months of work that count nowhere towards your pension. Unpaid work is also hard to claim — you have neither a contract nor any record of the hours you worked.
How do I recognise fake self-employment?
You invoice a single client, on their premises, with their tools, on their instructions and their schedule. That is dependent work, not business — and the inspectorate judges by the reality on site, not by the contract's title.
Part of my pay comes cash-in-hand. Problem?
Yes — off-book pay cuts your levy base, so sick pay, unemployment benefit and your future pension all shrink. And in a dispute over wages you can only prove the paper part; the rest stays word against word.
How do I do a one-off gig legally?
Either as occasional income up to CZK 50,000 a year, or on a DPP agreement with minimal paperwork. Both take only minutes to arrange and leave you with proof that the work was legal and that it was properly paid.
Can the inspectorate check me on site?
Yes — labour-inspectorate checks target construction, gastro and warehouses, and they also follow up on anonymous tips. The inspector asks on the spot who is working and under what contract, and you must produce it there and then.
