Substantial Presence Test Recordkeeping Checklist
What this page covers
Substantial Presence Test Recordkeeping Checklist
The substantial presence test is a calendar-day residency test. It looks at U.S. presence in the current year and the two prior years, so repeated short trips can still count.
Use this checklist to organize the facts that affect classification, including day counts, possible dual-status timing, green card status, and exceptions that may require a formal filing.
In brief
- Track U.S. presence for the current year and the two prior years because the test uses weighted days across all three periods.
- Check whether the current year includes at least 31 U.S. days and whether the three-year weighted total reaches 183 days.
- Keep separate notes for green card status, possible residency start and end dates, and any closer connection position that may require Form 8840.
What to do
Start with the day-count calculation. The substantial presence test generally requires at least 31 days in the current year and 183 weighted days over three years: all current-year days, one third of prior-year days, and one sixth of second-prior-year days.
Then separate physical presence from tax status. A person may be treated as a resident or nonresident depending on the green card test or the substantial presence test. In some cases, one tax year can include both resident and nonresident periods, creating a dual-status filing issue.
Finally, keep exception-related facts together. A closer connection exception is a separate procedural route when its conditions are met, including fewer than 183 actual U.S. days in the current year, a foreign tax home, a stronger connection to that foreign country, and Form 8840.
What to keep in mind
This page is most useful for people whose U.S. visits repeat across several years, especially when each trip feels short on its own. The test does not only ask whether you moved; it aggregates calendar presence under a formula.
It is also relevant when residency status may change during the year. The key issue may be not only whether someone is a resident, but which part of the year falls under which status.
This checklist is not a treaty analysis or a filing determination. If someone is classified as a nonresident and has a filing requirement, the relevant return may be Form 1040-NR, while treaty and withholding positions can involve separate forms and conditions.
