Yes, H-1B visa holders are generally required to pay Social Security (FICA) and Medicare taxes on their wages.

---

Here’s why:

• Unlike F-1 students, H-1B workers are considered resident aliens for tax purposes once they meet the Substantial Presence Test (usually after their first year in the U.S.).

• Resident aliens are subject to the same tax rules as U.S. citizens, including paying FICA taxes.

• Therefore, your employer should withhold Social Security (6.2%) and Medicare (1.45%) taxes from your paycheck.

If you notice FICA taxes not withheld while on H-1B, you should notify your employer.
