Why the W-4 Matters for F-1 and J-1 Visa Holders

The W-4 tells your employer how much federal income tax to withhold from your pay. Get it wrong, and you either owe money later or give the government an interest-free loan.

For non-resident aliens, this form is tricky. You are likely exempt from FICA taxes (Social Security and Medicare).

But the W-4 only handles federal income tax. Don't mix them up.

Resident vs. Non-Resident Status Changes Everything

Your tax status depends on the Substantial Presence Test. Most F-1 students are non-resident aliens for their first five calendar years. J-1 scholars usually get two years.

If you are a non-resident, you cannot claim standard deductions. This changes how you fill out the form. Claiming benefits you aren't eligible for leads to penalties later.
