Becoming an OSVČ in Czechia: trade office first, then tax and insurers

Becoming an OSVČ (osoba samostatně výdělečně činná, self-employed person) is one of the quicker ways to set up legally in Czechia. The state has built one front door, the trade licensing office, and much of what follows hangs on the registration you make there. The sequence is below, with the points where foreigners should check twice. If you are weighing it against a company, read OSVČ or s.r.o. first.

Check that you may work for yourself

Citizens of EU, EEA and Swiss states can trade in Czechia on the same footing as Czechs. Everyone else must first check whether their residence status allows business activity. Some permits allow work for one employer only, while others, permanent residence among them, allow self-employment. Registering a trade on a permit that does not cover it can put the permit at risk.

Ask the Ministry of the Interior, through its English pages or a migration adviser, before you register. It is the cheapest check in this whole process.

The trade office is the gate, but the permit decides whether you can walk through it. A foreigner on a work-linked permit who registers a trade without checking can put the permit at risk. That is the single most expensive mistake in the whole process, and it is avoidable with one email to the Ministry of the Interior.

Choose the trade

The Trade Licensing Act divides trades (živnosti) into categories. A "free" trade needs no qualification and is open to anyone meeting the general conditions of age, legal capacity and good standing. Craft and regulated trades require proof of qualification. Some professions, lawyers and doctors for instance, fall outside the Act and have their own registers.

The activity you list is not a slogan. It defines what you are authorised to do, and work that crosses categories may need more than one authorisation. Check the list of trades on the Business Portal of the Czech Republic before filing, and you avoid a second visit.

Register at the trade office

The živnostenský úřad is part of the local municipal authority. You apply on a single registration form, on paper at the office or at a Czech POINT, or electronically via the business portal with a data box or electronic identity. You give your identification, the address of your business premises (your home address can do, with the owner's consent if it is not yours) and the trade you are starting.

Foreigners may need to supply a criminal record extract from their home country, authenticated and translated, so ask the office what it needs for your nationality. A fee is charged for the registration (as of 2026; check the official source). Afterwards you receive an extract confirming your authorisation and your identification number, the IČO.

Then the tax office and the insurers

The single registration form has sections for the tax office, the social security administration and the health insurer. If you fill them in, the trade office forwards your registration and notifications; if you leave them out, the duties remain yours. Confirm with the tax office that you are registered for income tax and decide whether VAT applies. It is not automatic, since it turns on turnover and activity, and when to register for Czech VAT explains the principle.

Two insurance notifications matter. You must tell your health insurer that you have begun self-employment, within eight days of starting; your status decides whether you pay advances yourself. Self-employed third-country nationals without permanent residence are generally outside Czech public health insurance and need comprehensive commercial health insurance for foreigners instead (as of 2026; check the Ministry of the Interior and your insurer). And you must notify the district social security administration (OSSZ), part of the Czech Social Security Administration, by the eighth day of the month after you start, since a self-employed person pays pension and sickness insurance contributions under certain rules. Sickness insurance is voluntary for the self-employed. Pension insurance is compulsory when the self-employment is your main activity, or when income from it passes a set threshold.

The deadlines for these notifications are short, so check the current periods with the insurer and the social security administration, and keep proof of what the trade office forwarded for you. Contributions are paid as monthly advances and settled annually in an overview filed with each body.

How a sole trader is taxed

Business income goes into your personal income tax return. You can work out profit from actual expenses or, in many trades, from flat-rate expenses, a percentage of revenue (as of 2026; check the official source). The filing deadline is longer if a tax adviser files for you.

Small sole traders who qualify can instead use the paušální režim and pay one fixed monthly amount in place of the usual returns. Our explainer on the flat-rate regime covers who qualifies and what you give up.

Common mistakes

Newcomers stumble in predictable places. They register the trade and assume the tax office and insurers have been told everything, when some duties remain theirs. They assume sickness insurance is compulsory (it is voluntary for the self-employed) or that pension insurance is optional (it is compulsory when self-employment is the main activity, or when income passes a set threshold). They mix private and business money in one account. And they treat the trade registration as proof of residence, when the two are separate obligations.

A smaller but real trap is the description of the activity. Work that falls outside the trade you registered may need a second authorisation, and a client or an inspector can ask for it.

Records, invoices and an accountant

A sole trader keeps records of income and expenses, either full accounts or simplified tax records (daňová evidence), and retains documents for the period the law requires. Invoices must carry the details the law specifies, and VAT payers have a longer list. Open a separate bank account for the business even if the law does not demand it; mixing private and business money makes everything harder to follow.

For foreigners, the address on the trade registration does not replace residence registration, which is a separate obligation. Many self-employed foreigners hire an accountant from the start. Fees vary widely, so agree the scope and price in writing.

Before you go to the trade office, write down the exact activity, your residence permit type, the address you will use and the date you want to start. Book the office slot, and in the same week a short consultation with an accountant to plan the first year's insurance advances. Starting on a Monday is easier than on the last day of the month.

Where to check

The Business Portal of the Czech Republic, run by the state, lists the trades and the registration forms. The Financial Administration's English pages explain the tax side, and the Ministry of the Interior is the authority on whether your permit allows self-employment. If two sources disagree, the Ministry and the trade office decide.
