How do you get a tax ID in Slovakia in 2026?

The Financial Administration says a DIČ (the Slovak tax identification number) is given only to a taxpayer who must register for income tax. That covers someone who gets a business permit in Slovakia, starts another independent earning activity, or lets Slovak property. It also covers an entity that must withhold tax from employees.

An ordinary employee falls outside that list. The employer is the tax payer for payroll purposes: it registers with the tax office and withholds monthly advances from your wages. Expat tax advisers confirm that foreign workers on a Slovak or foreign payroll are not required to register personally with the tax office just because they work here.

When a foreign bank or form asks for your TIN (tax identification number), the tax office points you to your Slovak birth number (rodné číslo, the national personal ID) if you hold one and have no DIČ. Ask the Foreign Police or tax office whether a birth number has been assigned to you, because it is not something you can invent from your passport number.

The route starts at the trade licensing office, which issues the trade licence (živnosť). Business residence also requires a funded business account, 20 times the monthly subsistence minimum for a sole trader, as explained in How to apply for a residence permit. Once the licence is in place, you register with the tax office responsible for your registered address. The registration deadline for becoming a tax payer is tied to the month in which the duty arises, so do not leave it for the annual return.

Letting a Slovak flat creates a duty too, even if you live abroad. A freelancer who works from Bratislava but bills foreign clients is still carrying out independent activity on Slovak soil. The tax office says foreign customers alone do not qualify for the longer six-month filing extension, which is meant for income earned abroad. The ordinary extension is three months. Remote workers should read Best for remote workers before they pick a residence route, since Slovakia has no digital nomad visa.

Employees whose tax is handled by their employer normally rely on an annual reconciliation prepared by the employer. A personal tax return, when required, is due by 31 March after the tax year, and a three-month extension is possible if you notify the tax office. A tax resident of Slovakia is usually someone with a permanent home here or who spends more than 183 days in the country. Ask the employer's payroll team which case applies to you. If the employer is a Slovak company, the process is also described in Temporary residence for employment.

A bank may ask for a certificate of tax residence; the tax office issues one on a written request. Plan your first year's cash with How expensive is Slovakia and open an account early, so that your salary and your later tax payments go through one local IBAN.
