How do I calculate the 183-day rule?
First identify the exact period and counting method used by the relevant country, then total all qualifying days in that period. Do not assume every country uses the same method.

183-Day Rule Calculator
Many countries use a 183-day test in their tax-residency rules, but there is no single EU-wide formula. EuroPlanner tracks country days as an early warning.
Reaching 183 days can indicate tax residence, but day count alone is not a reliable final answer. National law, tax treaties, your permanent home and centre of vital interests may also matter.
How to use a day count
Add every stay in a country and review the total against the period used by that country's law. Some tests use a calendar year; others can use a tax year or rolling period. Confirm the correct method before relying on a total.
- Track partial travel days consistently.
- Keep separate totals for each country.
- Record plans as well as completed stays.
- Ask a qualified adviser when two countries may claim residence.
183 days is not the Schengen rule
The Schengen 90/180 rule concerns permission for certain short stays across the Schengen Area. Tax residence concerns a person's connection to one country and can affect EU citizens and non-EU citizens alike. Complying with one does not automatically satisfy the other.
When other tests matter
A permanent home, family links, economic interests, habitual abode and nationality can affect residence under domestic law or a bilateral tax treaty. Treaty tie-breaker rules may be needed when two countries consider the same person resident.
Frequently asked questions
Is 183 days the same in every European country?
No. The threshold is common, but definitions, periods, exceptions and additional residence tests vary by country.
Does staying fewer than 183 days guarantee non-residence?
No. A country may treat you as resident under other tests, including a permanent home or centre of vital interests.
Is the 183-day rule the same as Schengen 90/180?
No. One concerns tax residence in a country; the other concerns permitted short stays across the Schengen Area.
What if two countries consider me tax resident?
A bilateral tax treaty may provide tie-breaker tests. This is a situation for professional advice based on your facts.
