The Revenue Code uses an aggregate of at least 180 days in the tax year. This is a residence indicator, not a calculation of taxable foreign income or remittance treatment.
The rule
The counter indicates the statutory day threshold only. It does not determine which income is taxable, how remittances are treated, or the effect of a tax treaty.
Counting the days
Combines recorded visits, including arrival and departure dates.
- Choose the date through which you want to count, then add your recorded visits.
- Use the counting convention above. Overlapping recorded dates in the relevant region are counted only once.
- Read the result alongside the conditions. Missing records and other eligibility requirements are not inferred from a total.
Examples
These examples demonstrate the counter's arithmetic, using a count-through date of 30 October 2026. They do not determine legal status or eligibility.

Common misconceptions
“A count below the day threshold settles tax residence.”
A recorded-day total is one component. Review the separate conditions and exceptions described on this page.
“The window follows the latest twelve months.”
This counter uses the calendar year. A rolling window and a calendar year can produce different totals.
