How the Substantial Presence Test Works
The IRS uses the Substantial Presence Test to determine whether a foreign national living in the US is taxed as a resident alien (worldwide income, Form 1040) or a non-resident alien (US-source income only, Form 1040-NR). Meeting the SPT creates resident alien status.
The Formula
Step 1: Were you present โฅ 31 days in the current year? If no โ NRA (stop).
Step 2: Weighted total = Days(current year) ร 1
+ Days(prior year) ร 1/3
+ Days(two-prior year) ร 1/6
If weighted total โฅ 183 โ SPT MET โ Resident Alien (unless exempt or Closer Connection)
Exempt individuals (F-1 students within 5 years, J-1 teachers within 2 years, etc.):
Their US days do NOT count at all during the exempt period โ Always NRA.
Step 2: Weighted total = Days(current year) ร 1
+ Days(prior year) ร 1/3
+ Days(two-prior year) ร 1/6
If weighted total โฅ 183 โ SPT MET โ Resident Alien (unless exempt or Closer Connection)
Exempt individuals (F-1 students within 5 years, J-1 teachers within 2 years, etc.):
Their US days do NOT count at all during the exempt period โ Always NRA.

Important: The Closer Connection Exception cannot be claimed if you have applied for or taken any steps to change your status to that of a permanent resident. Even if you meet all other requirements, a pending green card application disqualifies the exception.
Frequently Asked Questions
What is the Substantial Presence Test (SPT) formula?
The SPT is met if you were present in the US for at least 31 days in the current year AND the weighted total is 183 or more days. The weighted total = all days in the current year (multiplied by 1) PLUS 1/3 of days present in the prior year PLUS 1/6 of days present in the year before that. For example: 150 days current year + 120 days prior year (ร1/3 = 40) + 90 days two-prior year (ร1/6 = 15) = 205 weighted days. That exceeds 183, so the SPT is met even though current-year days are only 150.
Which visa holders are exempt from counting days toward the SPT?
Several categories of individuals are "exempt" from counting their days toward the SPT: (1) F, J, M, or Q visa students during their first 5 calendar years; (2) J-1 teachers and researchers during their first 2 calendar years; (3) foreign government officials (A or G visa); (4) individuals with a medical condition that arose while in the US and prevented timely departure. These individuals' US presence days simply do not count toward the SPT during their exempt period โ they remain NRAs regardless of physical time in the country.
What is the Closer Connection Exception (Form 8840)?
Even if you meet the 183-day weighted SPT test, you can avoid US residency if: (1) you were present fewer than 183 actual days in the current year, AND (2) you have a closer connection to a foreign country than to the US (permanent home, family, business, licenses, bank accounts, etc. are all there). You claim this by timely filing Form 8840 (Closer Connection Exception Statement). Note: this exception is NOT available if you have applied for a green card (immigrant visa).
What is the Treaty Tie-Breaker rule for dual residents?
If you are treated as a US resident under the SPT AND also a tax resident of a country with a US tax treaty, you may be a "dual resident." Most US tax treaties include a tie-breaker provision (typically Article 4) that determines your single country of residence based on: permanent home โ center of vital interests โ habitual abode โ nationality โ mutual agreement. If the treaty makes you a resident of the other country, you still file a US return (1040) but claim non-resident treaty benefits and attach Form 8833 to disclose the treaty position.
What is the First-Year Election for a partial-year resident?
If you do not meet the SPT in the current year but you meet it in the following year, you can elect to be treated as a US resident for the last portion of the current year โ starting from the first day you were present for at least 31 consecutive days. This is called the First-Year Choice (Form 1040 with a statement). It can be beneficial if it lets you use the larger standard deduction and lower marginal rates on US income earned in the current year.
