IRS Substantial Presence Test

What is the test for U.S. residency?

The IRS Substantial Presence Test considers you to be a U.S. resident for tax purposes if you have been physically present in the U.S.:

for 31 days during the current year, and
for 183 days in the three years that include the current year and the two preceding years, on a weighted average basis.

Even if you meet the Substantial Presence Test, you may still qualify for an exemption from being considered a U.S. resident for tax purposes.

What are “Included Days”?

For the Substantial Presence test calculation, The IRS requires you to include:

All days spent in the U.S. in the current calendar year
1/3 of the days spent in the U.S. in the preceding calendar year
1/6 of the days spent in the U.S. in the calendar year prior to the preceding calendar year

In addition, be sure to use calendar days, not 24 hour periods. For example, if you enter the U.S. at 11:00 pm on a Thursday and leave at 1:00 am the following day, it would count as 2 days, even though you were only in the U.S. for 2 hours.
