Czech developers, designers and consultants usually work as an OSVČ (self-employed person) with a trade licence, known as a živnostník. Many of them pay a single monthly flat tax that covers income tax, pension and health insurance, and a foreign client withholds nothing. The catch is švarcsystém: a živnostník who in substance works as your employee is doing illegal work, and the fines are sized for companies.
The živnostník and the flat tax
Registration is a trade licence. Software development, IT consulting, hosting and web portals are field 56 of the volná živnost (free trade) (mpo.gov.cz, checked 2026-09-29). The contractor then invoices under their company ID (IČO), which you can check in ARES.
Most small contractors choose the paušální daň (flat tax regime). It replaces the income tax return and the separate social and health filings with one advance paid by the 20th of each month. Conditions: not a VAT payer, annual income up to CZK 2 million, no employment income beyond withholding-taxed amounts, not in insolvency (financnisprava.gov.cz, checked 2026-09-29). An identified person for VAT, which a contractor serving EU businesses becomes, can still use it (financnisprava.gov.cz, checked 2026-09-29).
| Band | Monthly advance 2026 | Of which income tax | Income ceiling |
|---|---|---|---|
| I | CZK 9,162 (CZK 9,984 until June) | CZK 100 | CZK 1m any income; CZK 1.5m if 75%+ is 80%/60% lump-sum income; CZK 2m if 75%+ is 80% income |
| II | CZK 16,745 | CZK 4,963 | CZK 1.5m any income; CZK 2m if 75%+ is 80%/60% lump-sum income |
| III | CZK 27,139 | CZK 9,320 | CZK 2m any income |
Band I fell by CZK 822 a month from July 2026 after a law cut self-employed pension contributions back to 1 January, leaving band I payers with a CZK 4,932 overpayment for January–June (financnisprava.gov.cz; bands and ceilings from financnisprava.gov.cz, checked 2026-09-29). None of this changes what you pay; the band is the contractor’s choice.
Expense lump sums outside the flat tax
A živnostník not in the flat tax files an annual return and may deduct a percentage of income instead of actual costs (Income Tax Act §7(7), checked 2026-09-29):
| Income type | Lump sum | Maximum deduction |
|---|---|---|
| Crafts, agriculture | 80% | CZK 1,600,000 |
| Other trade licences, incl. software | 60% | CZK 1,200,000 |
| Other self-employment (liberal professions, copyright) | 40% | CZK 800,000 |
| Rental of business assets | 30% | CZK 600,000 |
Income tax is 15%, and 23% on the part of the tax base above CZK 1,762,812 in 2026 (EY, checked 2026-09-29), with social and health contributions paid separately.
VAT. Registration is due once Czech turnover passes CZK 2,000,000 in a calendar year, or from the next day above CZK 2,536,500, under rules in force since 2025 (financnisprava.gov.cz, checked 2026-09-29). Services to businesses abroad do not count (jakpodnikat.cz, checked 2026-09-29). Invoices to EU businesses carry the reverse-charge note “daň odvede zákazník”.
Švarcsystém: where the arrangement breaks
The Labour Code defines dependent work as work done in a relationship of superiority and subordination, in the employer’s name, on its instructions and personally (§2, checked 2026-09-29). Performed outside an employment contract, it is illegal work. The party enabling it can be fined up to CZK 10 million, with a minimum of CZK 50,000, and the worker up to CZK 100,000 (suip.gov.cz; elegal.cz, checked 2026-09-29).
IT is not exempt. On 16 March 2026 the Supreme Administrative Court (7 Ads 52/2025) upheld a finding that a Brno IT company let three programmers do dependent work outside employment, looking at how the relationship worked in fact rather than at the contract’s label; the fine was CZK 85,000 after appeal (epravo.cz, checked 2026-09-29).
The definition may change. A bill approved by the government on 31 August 2026 would count work as dependent only when the client organises it, supervises it, gives instructions and sets working time, all together, from 1 January 2027 if Parliament passes it (advokatnidenik.cz, checked 2026-09-29). Until then, the current test applies.
Low-risk markers: deliverables rather than hours, the contractor’s own schedule and equipment, other clients, the right to use substitutes. High-risk: full-time for you alone, your manager assigning daily tasks, fixed hours, company email and title.
Contract and IP
- A written services agreement with the živnostník, scoped to deliverables, rate and currency, with the independence markers above.
- Software. Under the Copyright Act, economic rights cannot be transferred (§26), but computer programs and databases created on commission are treated as employee works: the commissioning client exercises the economic rights in its own name, and §61 on commissioned works does not apply (§58(7)). Say in the contract that the software is made to your order.
- Everything else (designs, copy, documentation): take an exclusive, worldwide licence in writing, including the right to modify and sublicense. Moral rights stay with the author.
Taxes and paperwork
The contractor’s side. Trade licence, flat tax or annual return, VAT registration as an identified person if serving EU businesses.
The client’s side. Pay gross against invoices; there is no Czech withholding for a foreign client. US payers collect a W-8BEN (W-8BEN-E from an s.r.o.) and file no 1099. Article 14 of the US–Czech treaty taxes a Czech resident’s independent services only in the Czech Republic unless the contractor has a US fixed base or spends more than 183 days in the US in twelve months (checked 2026-09-29).
How to pay contractors in the Czech Republic
| Method | What the contractor sees | Notes |
|---|---|---|
| Local CZK transfer | Koruna in a Czech account | Via a provider with local payout; CERTIS instant payments run 24/7 up to CZK 2.5m (cnb.cz) |
| SEPA transfer (EUR) | Euros in a EUR account | Cheapest if the contract is in EUR and you hold euros |
| SWIFT (USD) | Converted at the receiving bank’s rate | Receiving fees, e.g. CZK 100 at Fio banka (fio.cz) |
There are no currency controls. Rails, costs, failure points and platforms are compared in how to pay contractors in the Czech Republic.
Contractor of Record in the Czech Republic
A Contractor of Record signs with the živnostník in your place, which reduces misclassification risk where an engagement sits close to the §2 line. 4dev acts as Contractor of Record — the contracting party for each contractor — which reduces reclassification risk. Deel, Rivermate, Native Teams and Mellow also sell the model; what moves to the provider is set by the liability clause in its COR contract, not by the product name. Where the work is really a job, use an EOR. Compare providers in our COR rating.
