Track your US tax days before the 183-day rule catches you off guard. ResidencyProof is a tax day tracker for nomads, expats, visa holders, remote workers, snowbirds, and part-year residents who need to know how many days they have spent in the United States and each US state. The US 183-day tax rule is not always a simple calendar-day count. The Substantial Presence Test uses a weighted 3-year formula, and state residency rules can depend on day-by-day presence, domicile evidence, and where you can prove you actually were. ResidencyProof turns your location history into a clear daily record so you can track tax residency days, monitor your Substantial Presence exposure, and keep evidence organized before a CPA, tax attorney, or state tax agency asks for it. Built for US tax day tracking: • Track days spent in the United States • Monitor the US Substantial Presence Test • Count days by state for residency and domicile planning • Track California, New York, and other state residency exposure • Review a country-by-country and state-by-state timeline • Check your count as of today or a future filing date • Get alerts before you approach a threshold • Attach proof to specific dates and locations Stop relying on a spreadsheet for something this important. One missed trip, one wrong date, or one forgotten weekend can change your residency count. ResidencyProof helps you keep a cleaner record of where you were, how many days count, and what proof supports each location. Keep your evidence ready. Add leases, boarding passes, utility bills, receipts, travel confirmations, and other records to the dates and places they support. When your CPA, tax attorney, immigration lawyer, or a state tax agency asks how you counted your days, your timeline and documents are already organized. Useful for: • US expats watching Substantial Presence exposure • Visa holders tracking US tax residency risk • Digital nomads and remote workers moving between countries • Snowbirds splitting time between states • People leaving California, New York, or another high-tax state • Frequent travelers who need a reliable record of where they were ResidencyProof also supports other physical-presence rules, including Schengen 90/180, Canada permanent resident obligation, Canada citizenship physical presence, US naturalization, UK ILR absences, Australia Resident Return Visa, and New Zealand permanent resident presence.
