What does this tax residency calculator estimate?
It estimates how many days of your stay fall inside 2026 for one country, then adds any earlier days you already spent there in 2026. It is a planning aid, not a legal conclusion.
Estimate how many days of a stay count toward 2026 and whether you are getting close to a common planning benchmark.
Prefilled for Czech Republic, so you can go straight from research into a day-count check.
This is a planning tool, not a legal conclusion. Tax residency can also depend on local ties, treaty position, and fact-specific rules.

Yes. It only counts the portion of the trip that falls inside 2026. If your trip starts before 2026 or ends after it, only the overlap with 2026 is included in the result.
Because day count is only one piece of tax residency analysis. Many countries use a 183-day style benchmark, but local rules, ties, treaty position, and factual circumstances can still matter.
Use the estimate to decide whether you are comfortably below a benchmark, getting close, or already in the danger zone. Then verify the current rules on official sources and, if the numbers are close, get local tax advice before making a long-stay plan.
