Slovakia Tax Residency (183-day rule)

Key parameters
Threshold	183 days
Period / Window	Calendar year (1 Jan – 31 Dec)
Counting	Any part of a day
Alternative	Permanent address, dwelling

Slovak residence turns on where you are registered, where you keep a home, and how long you stay. Nationality plays no part, and any one of three conditions is enough:

• Permanent address — you have a permanent address registered in Slovakia.
• Dwelling — you have accommodation in Slovakia that is not merely for occasional use, and the surrounding facts, including your personal and economic ties, show you should be staying there permanently.
• Habitual stay — you are physically in Slovakia for 183 days or more in the calendar year.

A stay that is only for study or medical treatment does not make you resident on the habitual-stay condition, however long it runs. The carve-out follows the purpose of the stay, not the visa or permit you hold.

Residents are taxed on their worldwide income. Nonresidents pay Slovak tax only on Slovak-source income.

• A dwelling can make you resident on very few days. An apartment kept available to you year-round, alongside personal and economic ties, points at permanence in a way that a holiday let does not.
• A registered permanent address is a condition in its own right. It can make you a Slovak resident even in a year you spent almost entirely abroad, for as long as the registration stands.
• The study and treatment carve-out is narrow. It only rescues you from the habitual-stay condition. A student who also registers a permanent address or keeps a settled home is resident on the other route.
• A double taxation agreement can move residence. Where Slovakia and another country both treat you as resident, the agreement in force applies its tie-breaker, and Slovak domestic law defers to that outcome.
• Residence attaches to the whole year. Slovakia looks at the calendar year as a unit, so the months before you qualified are inside the same tax year rather than treated separately.

Residents are taxed on worldwide income while nonresidents pay only on Slovak-source income, so a misjudged position usually surfaces as foreign income left undeclared. Where an audit assesses additional tax, the penalty runs at three times the European Central Bank base rate a year, and 10% a year applies instead wherever that calculation falls short of it. The rate is fixed by reference to the day the assessment is delivered. Professional tax advice is strongly recommended in situations like this.

A working year over the threshold

You take a contract in Bratislava from February to October. Counting every started day, your presence passes 183 days in the calendar year, and you are a Slovak resident for that year.

An apartment that decides it

You keep a flat in Košice available all year, your partner lives there and your business income comes from Slovak clients, but you travel constantly and spend 90 days in the country. The dwelling condition makes you resident anyway.

A student who stays under the rule

You spend 10 months in Bratislava on a degree course, living in university accommodation and with no permanent address registered. The stay is for study, so it does not make you resident on the habitual-stay condition.
