Immigration Status vs. Tax Residency: The IRS does NOT determine tax status by visa type. Tax residency is determined by physical presence days under 26 U.S.C. § 7701(b).
The 183-Day Weighted Presence Formula
To meet the Substantial Presence Test and become a Resident Alien, you must be present in the U.S. for at least:
- 31 days during the current calendar year, AND
- 183 days calculated over the 3-year period: 100% of current year days + 1/3 of prior year days + 1/6 of 2nd prior year days.
Exempt Individuals (F-1 & J-1 Exceptions)
"Exempt Individual" means exempt from counting physical presence days toward the Substantial Presence Test:
- F-1 / J-1 Students: Exempt for 5 calendar years. Submit annual Form 8843.
- J-1 Scholars / Researchers: Exempt for 2 calendar years. Submit annual Form 8843.
Frequently Asked Questions (FAQ)
Under 26 U.S.C. Section 7701(b), the Substantial Presence Test evaluates physical presence over a 3-year period: 100% of days present in the current year + 1/3 of days in the 1st prior year + 1/6 of days in the 2nd prior year. If the total equals 183 weighted days or more (and you spend at least 31 days in the current year), you are classified as a Resident Alien for tax purposes.
Resident Aliens (who meet the Green Card test or Substantial Presence Test) are taxed on worldwide global income and file IRS Form 1040. Nonresident Aliens are taxed ONLY on U.S.-sourced income and file IRS Form 1040-NR.
An 'Exempt Individual' is exempt from counting physical presence days toward the 183-day Substantial Presence Test. F-1/J-1 students are exempt for their first 5 calendar years; J-1 researchers/teachers are exempt for 2 calendar years. All exempt individuals must file annual IRS Form 8843.
Under Treasury Regulation § 301.7701(b)-2, an individual who meets the Substantial Presence Test but spends fewer than 183 days in the U.S. during the current calendar year can file Form 8840 to declare closer personal and economic ties to a foreign country, remaining a Nonresident Alien.
A Dual-Status alien is classified as both a Nonresident Alien and a Resident Alien in the same tax year (e.g., entering the U.S. mid-year on an H-1B visa). They file Form 1040 as their primary return with Form 1040-NR attached as an informational statement.
Yes. Once an individual becomes a Resident Alien under the Substantial Presence Test or Green Card test, their global income (foreign rental income, bank interest, capital gains) becomes subject to U.S. federal taxation, and foreign accounts are subject to FBAR (FinCEN 114) and FATCA (Form 8938) reporting.
