What's New in Flags
2.4
October 11, 2026
The UK day limit now depends on whether you're arriving or leaving. Tell Flags whether you were UK resident in any of the last 3 tax years, and it uses the matching HMRC ties table. If you're not a US citizen, Flags now applies the US substantial presence test: this year's days, plus a third of last year's and a sixth of the year before. The US screen shows all three years. Fixed: days left was one day too high. It now shows the days you can spend and still stay under the threshold. In Settings, Flags Schengen and Flags Map show their new icons, and the support, privacy, and terms links open the Flags Tax pages.
