Tax-residency day counter
Pick a destination and enter the days you have spent (and plan to spend) there this tax year. This tool compares your days against that country's headline day-count threshold — usually 183 days — and tells you whether you are likely resident, maybe resident, or probably not, adjusting if you keep a home there. It is a rough check: real residency also turns on a permanent home, family ties, centre of life and treaty tie-breakers, so it is not decisive and not tax advice.

How tax residency actually works
Most countries use a day count (typically 183 days in a tax year) as the headline trigger, but it is rarely the whole story. They also test where your permanent home is, your centre of vital interests (family, economic ties), and sometimes domicile or a multi-year look-back. A handful of countries (the Netherlands, Belgium, several others) have no fixed day count at all and decide purely on facts. If two countries both claim you, the relevant tax treaty tie-breaker decides which one wins.
That is why a day counter can only flag risk, not give an answer. Track your days carefully, keep evidence of your main home, and read the tax-residency explainer and your destination's full country profile.
Frequently asked questions
How does the tax-residency day counter work?
Pick a destination and enter how many days you have spent (and plan to spend) there in the tax year. The tool compares your days against that country's headline day-count threshold (often 183 days) and tells you whether you are likely resident, maybe resident, or probably not — adjusting if you keep a home there. It runs entirely in your browser using our committed dataset of 65 countries.
Is the day counter enough to decide my tax residency?
No. A day count is only the headline test. Most countries also look at where your permanent home is, your family and economic ties, your centre of life, and (for dual residents) treaty tie-breaker rules. Some countries have no day count at all. Use this as a directional check, then confirm with the country's tax authority and a cross-border adviser.
Why does keeping a home there change the result?
Because many residency tests are triggered by having a permanent home available to you, independently of days. If you keep a home in the destination, you can be treated as resident even below the day threshold — which is why the tool flags more caution when you answer 'yes'. Not tax advice.
