Description
Do you know how many days you've spent in each state this year? Your tax bill depends on it.
Tax Days tracks your days against the residency rules that matter — so you always know exactly where you stand. Log your trips, and the app does the math across US states, the federal Substantial Presence Test, Schengen 90/180, UK Statutory Residence Test, and more.
HOW IT WORKS
1. Choose your jurisdictions from 315 countries, states, and regions
2. Log your trips — arrival date, departure date, and where you went
3. See your status instantly — progress bars show how close you are to each threshold
4. Get warned before you cross a line — notifications alert you at 30, 14, 7, 3, and 1 days out
FEATURES
• Real-time dashboard with rule status across all your jurisdictions
• Interactive calendar — see your entire travel year at a glance, tap dates to add trips
• US state rules: NY 184-day + abode, CA 9-month safe harbor, and all 183-day states
• Federal Substantial Presence Test with full 3-year weighted calculation
• Schengen 90/180 rolling window tracker
• UK Statutory Residence Test (April–April tax year)
• Year-over-year stats and jurisdiction breakdowns
• Search across all your trips and jurisdictions
• iCloud sync across all your devices
• Trip conflict detection — overlapping trips flagged automatically
• 100% private — no servers, no accounts, data stays on your device
WHO IS THIS FOR?
• Snowbirds splitting time between New York and Florida
• Remote workers hopping between states without realizing the tax consequences
• Frequent international travelers tracking the Substantial Presence Test
• Digital nomads watching their Schengen days
• Expats who need to know where they stand
• Anyone whose accountant said "you need to start tracking your days"
