The rules around tax residency are complex and vary significantly by country. These guides cut through the jargon so you know exactly where you stand — before you talk to an accountant, and before you file.
Most countries use some version of a day-count threshold to determine tax residency. Understand how the rule works, where countries differ, and what happens if you cross the line.
The IRS uses a weighted three-year formula, not a simple 183-day count. Learn the exact math, which days don't count, the Closer Connection Exception, and treaty tiebreakers.
Spreadsheets fail audits. Tax authorities want an audit trail with timestamps, not just a final count. Here's what a compliant tracking system actually needs.
DayTrace automatically counts your days, alerts you before thresholds, and generates the audit trail your accountant needs.
