How the count works Each stay counts the arrival day and the departure day as full days, and each calendar day is counted once even if two stays overlap. In calendar mode only days inside the chosen tax year count. In rolling mode the tool finds the 365-day window with the most days in it. Reaching 183 days is a common test for tax residency, but it is only one test. Many countries also look at your home, family, work and where your life is centred, and some count partial days or transit days differently. Tax treaties can change the result. Estimate only. Tax residency rules vary by country. Check with the tax authority of the country, or a qualified tax adviser, before you rely on this. pc-result pc-label pc-input pc-label pc-input pc-btn-secondary pc-btn-sm Every stay needs a valid arrival and departure date.
