Slovakia's 183-Day Tax Residency Rule

At least 183 days in a calendar year is one route to Slovak tax residency. Here is exactly how the count works.

Last verified: August 2026

In short: presence of at least 183 days in a calendar year is one route to Slovak tax residency, so the line is crossed on day 183 rather than day 184. Every started day counts, however short, which means arrival and departure days both count. Registered permanent residence or a dwelling you intend to live in permanently are separate routes in, and either can make you resident with no days of presence at all.

Threshold: At least 183 days, so day 183
Counting window: Calendar year
A day counts if: You were present for any part of it
Other residence tests: Permanent residence, dwelling with intent to reside
Tax year: Calendar year
Legal basis: Act No. 595/2003 Coll., Section 2

The rule

Slovakia treats you as habitually staying in the country, and therefore as a tax resident, if you stay there at least 183 days in the relevant calendar year, whether continuously or across several periods. Three points decide most real cases:

The threshold is inclusive. The law says at least 183 days, so a year with exactly 183 qualifying days meets this test. There is no need to reach 184.
Every started day counts. Any part of a day, however short, is a day of presence. Both the arrival day and the departure day count, and so does a single-day visit.
The window is the calendar year, and only the calendar year. The Slovak tax authority states explicitly that the 183 days are measured in the relevant calendar year and not in any twelve-month period, so the count resets on 1 January.

How to count it

Slovakia counts calendar days of physical presence, not nights, so a stay of a single afternoon still adds a day to the total.

List every Slovakia trip with its arrival and departure dates.
Count every day on which you were in the country, including the arrival day and the departure day.
Add the stays together across a single calendar year. They do not need to be consecutive.
If the year total reaches 183, the day-count test is met.

Example. You spend 100 days in Slovakia between January and April, then return for another 83 days between September and November.

Neither stay comes close on its own, but the law adds them together: 100 plus 83 is 183, and 183 is enough. The test is met exactly at the line, without a single day to spare.

Beyond the day count

The day count is one of three independent routes, and it is the only one a calendar can answer. Registered permanent residence in Slovakia makes you a resident on its own, even if you have lived abroad for years, and so does a dwelling that is available to you for more than occasional use in circumstances showing you intend to live there permanently. Staying under the line therefore does not make you a non-resident. There is one narrow exception in the other direction: someone whose habitual stay in Slovakia is solely for study or medical treatment keeps limited tax liability despite the days. And if another country also claims you, a double-tax treaty decides residency through tie-breaker rules such as permanent home and centre of vital interests. One consequence worth planning around: once you reach 183 days, you are a Slovak tax resident for the whole tax period, not from the 183rd day onward.

FAQ

How many days can you stay in Slovakia without becoming a tax resident?

Up to 182 days in a calendar year under this test. Reaching 183 days is enough, because the law says at least 183 rather than more than 183.

Do arrival and departure days count in Slovakia?

Yes. Every started day of stay counts, however short, so both ends of a trip count and a same-day visit counts as a full day.

Can you be a Slovak tax resident with fewer than 183 days?

Yes. Registered permanent residence in Slovakia, or a dwelling you intend to occupy permanently, makes you a resident regardless of how many days you spend there.
