While US employees use Form W-4 to control withholding on wages, foreign individuals use W-8BEN to avoid excessive withholding on US-source income like dividends, interest, royalties, and sometimes wages.

W-8BEN vs. W-4: Which form should you use?
If you're starting your first job in the US on a work visa, you might be confused about whether to file W-8BEN or W-4 with your employer. The answer depends on your tax residency status, not your visa status.
Use Form W-4 if you're a "resident alien" for tax purposes:
Use Form W-8BEN if you're a "nonresident alien" and qualify for treaty benefits:
Example: First-year H-1B worker from India
Raj starts his first US job in January 2026 on H-1B, earning $85,000. Since he just arrived, he's a nonresident alien for tax purposes.
Option 1: No treaty claim
Option 2: Files W-8BEN claiming US-India tax treaty
Important: W-8BEN doesn't always help with wages
Many new workers think W-8BEN will reduce their paycheck withholding like W-4 does. This isn't always true:
When you'll transition from W-8BEN to W-4
Most entry-level workers eventually become resident aliens and switch to W-4:
Year 1: Nonresident alien, may use W-8BEN for applicable income
Year 2-3: Likely becomes resident alien, switches to W-4
Result: Significantly lower withholding and higher take-home pay
Track your days in the US carefully – this transition can save you thousands in overwithholding.
Key takeaway: Most entry-level workers on visas will eventually use W-4 instead of W-8BEN once they become resident aliens, typically resulting in lower withholding and higher take-home pay.
Key Takeaway: Entry-level visa workers typically transition from W-8BEN to W-4 after 1-2 years, often reducing withholding by thousands annually.
