Czechia taxes sex work but still won’t license it — what the courts just settled

What the Constitutional Court decided

On 20 October 2026 the Czech News Agency (ČTK) reported two rulings from the Constitutional Court (Ústavní soud) that close a dispute running for more than a decade. The court rejected two complaints by a woman whom the tax authorities had retroactively assessed for the years 2013 and 2014. The assessment exceeded CZK 900,000 for each year.

The tax office had noticed that she regularly exchanged large sums of euros into crowns and deposited them in her bank accounts without ever filing a tax return. She did not dispute where the money came from: it was income from prostitution, which she argued was not taxable at all.

The court disagreed on every point. Its reasoning, in the words of judge-rapporteur Jiří Přibáň, is that tax law rests on economic substance: what is taxed is the real gain and the increase in wealth, not the legal or moral purity of the title under which it was obtained. Taxation, the court wrote, is neither moral approval nor state accreditation of the activity.

Two further arguments failed. The complainant said that if the state collects tax on prostitution it becomes a pimp, in conflict with the criminal ban on procuring (§ 189 of the Criminal Code). The court answered that the state is not enriching itself on someone else’s work; it is distributing the tax burden fairly and regulating a market. It added that treating income from voluntary sex work as legitimate, and therefore taxable, can only strengthen the social standing of the people earning it in the long run.

The second ruling, with judge-rapporteur Veronika Křesťanová, dealt with legitimate expectation. The complainant pointed to repeated statements by politicians that prostitution is not taxed, and to the fact that the authorities had not taxed such income before. The court found no evidence of a legally protected expectation of exemption. Political statements do not create one, and an authority addressing a question for the first time is not acting unconstitutionally by doing so.

The 2025 judgment it confirms

The Constitutional Court did not create a new rule. It confirmed the Supreme Administrative Court (Nejvyšší správní soud, NSS), whose judgment 22 Afs 24/2025-48 of October 2025 was the first time a Czech top court said plainly that income from voluntary prostitution is taxable like any other income from self-employment.

The NSS had to deal with the same objections and set them aside one by one. The Income Tax Act neither explicitly excludes nor exempts income from prostitution, so the general rule applies. International conventions against trafficking and the exploitation of prostitution do not stand in the way, because they target exploitation by third parties, not an adult’s own voluntary work. And the criminal ban on procuring does not make the activity itself a crime; under current Czech law, voluntary prostitution by an adult is not an offence.

What the NSS left open, and the Constitutional Court did not need to answer, is the technical question of which income category applies: business income under § 7 of the Income Tax Act, or “other income” under § 10. That distinction decides the deductions available and the social and health insurance consequences. In practice the income is usually declared under § 10, but that is established practice, not an explicit rule.

Taxable, but not licensable

This is where Czechia is unusual. The same state that now taxes sex work as self-employment still refuses to license it as a trade. The Trade Licensing Act (zákon č. 455/1991 Sb.) excludes prostitution from its scope outright, in § 3(3)(p). A provider cannot obtain a živnostenský list for what she does, cannot register the activity, and has no regulator to deal with.

What exists instead is a patchwork:

• No licensing path. Providers who want a formal footing register a related free trade (personal services, modelling, social companionship), or declare the income as “other income” under § 10. Neither describes the work.
• No national regulation. The 1922 Act on combating venereal diseases, the last statute that said anything about prostitution as such, was repealed as of 1 January 2024. Nothing replaced it.
• Municipal ordinances only. Towns can ban the offering of sexual services in public spaces by ordinance, and dozens have; Prague and Brno cover their whole territory. These target the street, not discreet advertising or private meetings, and carry fines of up to CZK 100,000.
• Health insurance regardless. Everyone in Czechia is insured. A provider who is not an employee, a registered self-employed person or a state-insured category is an “osoba bez zdanitelných příjmů” (OBZP) and pays the minimum premium herself, roughly CZK 3,000 a month in 2026.

Germany went the other way in 2017: the Prostitute Protection Act (ProstSchG) created a mandatory registration, a health-counselling certificate and, with it, a clear tax status. Whatever one thinks of that law, it is at least internally consistent. Czechia now has the tax half of a regulatory framework without the regulatory half. Our German guide explains the ProstSchG mechanics for comparison: Das ProstSchG erklärt.

What it means for providers in Czechia

For anyone working in Czechia, the practical consequences are now settled, and they are not new. The courts have spelled out what the tax office has assumed since at least 2013:

• Declare the income. The “it isn’t taxable” argument has been tried at every level and lost. Retroactive assessments reach back years and come with interest and penalties; the case that just ended concerned tax years more than a decade old.
• Bank records are the trigger. The assessment in this case started with regular currency exchanges and deposits. Cash that becomes a bank balance without a declared source is exactly what the Financial Administration looks for.
• Politicians’ assurances are worth nothing. The legitimate-expectation argument was the complainant’s strongest, and the court rejected it for lack of any evidence that the state had promised an exemption.
• Get the form right once. § 7 or § 10, a related free trade or none, OSVČ or OBZP for insurance: an accountant who knows the situation settles this in a single consultation. Fixing it after an audit is always more expensive.

Regulation by tax office

The Constitutional Court said something that goes beyond this one case. By calling the income legitimate and arguing that taxing it strengthens the social standing of the people who earn it, the court has effectively taken a position on a question parliament has avoided for twenty years. Bills to regulate prostitution have been proposed repeatedly since the mid-2000s; none has passed.

The result is regulation by tax office. The one state body with a settled view of sex work in Czechia is the Financial Administration, and its view is that the work is ordinary self-employment. Every other institution, from the trade licensing offices to the health system, still treats it as something that does not formally exist. A provider can be audited for income from an activity she is not allowed to register.

That gap matters for the debate elsewhere in Europe. Advocates of the Nordic model argue that the state should never treat sex work as work; the Czech courts have now said, in the narrow context of tax, that it must. Advocates of the German model point to registration as the price of legitimacy; Czechia shows legitimacy can arrive through the tax code first, with the rights and protections of a recognised trade still missing.

Our view

EscortFox is a classifieds directory. Providers in Czechia advertise their own services on it directly, at no commission, because that is the only model Czech law allows: a platform that took a cut would be procuring. We have no stake in whether sex work is taxed. We do have a stake in providers not being ambushed by rules nobody wrote down.

The courts have done their part. Income from voluntary sex work is taxable, and the reasoning is sound: economic substance over moral judgement. The missing piece is the one the courts cannot supply. If the state taxes the activity as self-employment, it should let people register it as one, with the insurance status, the deductions and the legal certainty that every other self-employed person in the country takes for granted. Until parliament does that, the tax office will remain the only regulator sex workers in Czechia have.
