What is the Substantial Presence Test and How Does It Affect You?

Definition & Meaning

The substantial presence test is a method established by the Internal Revenue Service (IRS) to determine if a foreign national qualifies as a resident alien for tax purposes in the United States. To meet this test, an individual must be physically present in the U.S. for a minimum of:

  • 31 days during the current year, and
  • 183 days during a three-year period that includes the current year and the two preceding years.

When calculating the 183 days, all days present in the current year are counted, along with:

  • One-third of the days present in the first year before the current year, and
  • One-sixth of the days present in the second year before the current year.

Real-world examples

Here are a couple of examples of abatement:

(Hypothetical example) A foreign national spends 40 days in the U.S. in 2023, 90 days in 2022, and 60 days in 2021. To determine their residency status:

  • Days in 2023: 40 days counted.
  • Days in 2022: 30 days counted (90 days x 1/3).
  • Days in 2021: 10 days counted (60 days x 1/6).

Total: 40 + 30 + 10 = 80 days. This individual does not meet the substantial presence test.
