Schengen 90/180 calculator 2026: days used and your last day to leave

The Schengen limit is recalculated every single day, and that is what makes it misleading. The European Commission puts it this way: on a short stay you may usually remain for up to 90 days in any 180-day period, and you must count back 180 days from each day of your stay to check that the total does not go over 90. So there is no reset date, no quarter, and no count that restarts on 1 January. A day becomes available again only when it drops out of the window, 180 days later. This counter starts from your past stays and an entry date, then gives the last day you can stay. One point needs saying first, because this site is mainly about tax: this count is a rule on entry and stay, and keeping to it settles no question of tax residency.

Two counts that never talk to each other

It is tempting to merge them, as both are days on a calendar. But they answer different questions: one says whether you may stay, the other where you can be taxed.

Two authorities say so in their own words. The Spanish tax agency notes that you can hold a residence permit in a country without being treated as tax resident there. The UAE tax authority's guide says tax residency differs from other kinds of residency, such as for immigration, and that you can be a tax resident with no Residence Permit. It also runs the other way. Staying under 90 days gives no tax protection: Swiss federal law speaks of a stay of 30 days without significant interruption with paid work, and Switzerland is in the Schengen area. Thirty days of work there sit well inside the visa limit and can already matter for tax.

A worked case, start to finish

Take two stays: 10 January 2026 to 5 March 2026, then 20 April 2026 to 5 May 2026. You plan to enter again on 1 July 2026. The engine, which counts entry and exit days as days of stay, finds 71 days already used in the 180 days ending the day before that entry. Plain subtraction, a balance of 19 days from entry, would give 19 July 2026. The engine gives 12 September 2026 as the last possible day.

The gap comes from the January to March days, which drop out of the window while you are there. Each day that leaves frees up another, until the window has nothing left to give back. That is why the counter tests every day one by one. The Commission's own calculator does this check too, with a check mode for past and current stays and a planning mode for a future entry. If it disagrees with ours, or if you are within a few days of the limit, go by the Commission's tool.

What we do not claim about the European text

We could not open the Schengen Borders Code on EUR-Lex. This page therefore rests on the Commission's pages, and we cite no article of the regulation. Those pages do not say in so many words that entry and exit days each count as a day: our counter counts both, which is the cautious choice, and the official calculator remains the reference. Nor do we give the penalties for an overstay, because we have not read them in an official source.

Who follows this rule, and who falls outside it

The Commission sets two cases aside. If you hold an EU residence permit or a long-stay type D visa, the rule does not apply to you, and those periods do not go in the calculator. If you hold a short-stay visa whose authorised stay, printed on the sticker, is shorter than 90 days, it tells you not to use the calculator: that shorter stay is what counts for you.

The EU's Your Europe page adds that some nationalities need a visa and others are exempt for stays of 90 days or less. Either way, the limit is reasoned on the same basis. Check with the consulate of the country you are visiting what applies to your passport.

The 29 countries in the count, and the two exceptions

According to the Commission, the area has 29 countries: 25 EU Member States and 4 non-EU countries, Iceland, Norway, Switzerland and Liechtenstein. Bulgaria and Romania were the last to join, on 1 January 2025. All of them count together: ten days in Lisbon and ten in Athens make twenty days.

Two EU countries stay apart. Cyprus takes part in Schengen cooperation, but the Council has not yet lifted its internal border controls. Ireland has an opt-out and keeps its own visa and border policies. On a tax calendar this can run against instinct: days in Ireland stay out of the Schengen calculator, yet they go into the Irish count of 183 days.

Since April 2026, your passport is no longer your only trace

The Entry/Exit System (EES) now registers non-EU nationals on short stays each time they cross the external borders of the 29 countries using it. The Commission says it has replaced passport stamping since 10 April 2026 and allows overstayers to be detected automatically. It holds your name, travel document data, biometric data, and the date and place of entry and exit.

Two practical results follow. Old stamps will no longer help you find recent dates, so note them yourself as you travel. And a slip in a hand-kept count is now easier for the authorities to see than for you. This data is there for border management: its existence does not make it proof of tax residence, and we have read nothing that says otherwise.

Counting Schengen and tax from the same dates

When you live between countries, the two counts end up sharing one diary, and one trip can be harmless for the first and decisive for the second. Enter your dates here for the visa question, then reuse them in the 183-day counter or on the country page for tax. If you want one log to hold both, the Taxlag app offers a Schengen threshold for non-European passports, next to its tax thresholds.
