The Internal Revenue Service requires a specific W‑8 form for each type of U.S. source income. Selecting the wrong version can trigger unnecessary withholding, delay payments, or expose you to compliance risk. Understanding the distinctions ensures you claim the correct treaty rate and remain compliant.
Non‑resident aliens often receive dividends, royalties, or services payments. Each category interacts with a different W‑8 form, and the eligibility for treaty exemptions varies. By comparing the forms side by side, you can see exactly where the overlap ends and the unique requirements begin.
