NRI Tax Status Checker
Run the actual IRS Substantial Presence Test on your day counts to see whether you're a resident or nonresident alien for US tax purposes.
Weighted day count (IRS formula)
Educational estimate of the Substantial Presence Test only — not a full filing-status determination. Dual-status years (the year you cross from nonresident to resident), treaty tie-breaker elections, and first-year choice can change the outcome; confirm with a CPA experienced in cross-border filings before you file.
