Introduction

401(k) plans are one of the most powerful retirement savings tools in the U.S. However, for non-U.S. individuals—such as foreign workers, international students, or expatriates—the rules and benefits can be quite complex. Whether you're a non-resident alien earning income in the U.S. or a green card holder, understanding the details of 401(k) plans can help you secure your financial future.


This guide from Learn with Manika simplifies the 401(k) landscape for non-U.S. citizens. Let’s get started!


1. What is a 401(k) Plan?

A 401(k) is a retirement savings plan sponsored by an employer. It lets employees save a portion of their salary pre-tax or after-tax (Roth), and often includes employer matching contributions.


Key Features:

  • Tax-deferred growth

  • Employer contributions

  • Contribution limits

  • Withdrawal rules


2. Are Non-U.S. Citizens Eligible for 401(k)?

Yes, non-U.S. citizens can participate in a 401(k) if they:

  • Work for a U.S. employer offering a 401(k)

  • Have a valid Social Security Number (SSN) or Taxpayer Identification Number (TIN)

  • Receive W-2 wages from the employer


Exceptions:

  • Independent contractors and F1 visa holders may not qualify

  • Non-resident aliens not paying U.S. taxes are often ineligible


3. Types of 401(k) Plans

TypeDescription
Traditional 401(k)Contributions are made pre-tax, reducing current taxable income
Roth 401(k)Contributions made with after-tax income; withdrawals are tax-free
Solo 401(k)For self-employed individuals with no full-time employees
Safe Harbor 401(k)Designed to pass IRS non-discrimination tests easily


4. Contributions, Limits & Employer Matching

2025 Contribution Limits:

CategoryAnnual Limit
Employee$23,000
Catch-up (50+)Additional $7,500
Employer + Employee Total$69,000


Employer Matching:

  • Usually 50% of the first 6% you contribute

  • Varies by employer


Example: If you earn $100,000 and contribute 6%, employer matches 3% → $9,000 total annually


5. Tax Implications for Non-U.S. Individuals


Tax Benefits:

  • Traditional 401(k): Reduces taxable U.S. income

  • Roth 401(k): Withdrawals are tax-free if rules are followed


Double Taxation Issues:

  • May face tax in both the U.S. and your home country

  • Tax treaties (India, UK, Canada, etc.) may reduce double taxation


Key Tip:

File IRS Form W-8BEN if you’re a non-resident to claim treaty benefits.


6. Withdrawals, Penalties & Rollovers

Withdrawal Rules:

  • Allowed after age 59½

  • Early withdrawals taxed + 10% penalty


Exceptions:

  • Disability

  • Substantially equal periodic payments

  • Qualified hardships


Rollovers:

  • Can rollover to IRA

  • Must complete within 60 days to avoid taxes


Example: You move back to India and want to withdraw $50,000 before age 59½. Expect 30% U.S. withholding + Indian tax (unless treated as income exempt by treaty).


7. Managing 401(k) After Leaving U.S.

Options:

  1. Keep it in the U.S. (if allowed)

  2. Roll over to an IRA

  3. Withdraw (watch out for taxes)


Practical Tips:

  • Use a U.S. bank account to manage payouts

  • Monitor currency exchange rates

  • Consult a cross-border tax advisor


8. Practical Examples

Example 1: Raj, H1-B Visa Holder

Raj works at Google on an H1-B visa. He contributes 10% to his 401(k) and receives a 4% employer match. He saves ~$14,000/year. When he returns to India after 5 years, he rolls over his $70,000 to a U.S. IRA to defer taxes.


Example 2: Lisa, Non-Resident Alien

Lisa worked 2 years in the U.S. under L1 visa, and contributed to a Roth 401(k). Upon returning to Germany, she kept the funds in her U.S. account and will withdraw them post-retirement, avoiding taxes due to the U.S.-Germany tax treaty.


10. FAQs

Q1: Can I contribute to a 401(k) if I’m on an F-1 visa?
A: Generally no, unless you become a resident alien for tax purposes.

Q2: What happens to my 401(k) if I leave the U.S.?
A: You can leave it, roll it over to an IRA, or withdraw with tax implications.

Q3: Is my 401(k) taxable in my home country?
A: Depends on tax treaties. Consult a tax professional.

Q4: Can I open a 401(k) on my own?
A: Only if you are self-employed (Solo 401(k)).

Q5: Do I need a U.S. bank account to access my 401(k)?
A: Highly recommended for easier management and payouts.


Conclusion

401(k) plans offer an excellent way for non-U.S. citizens working in America to save for retirement. However, understanding the tax rules, contribution limits, and withdrawal guidelines is essential to maximize benefits and avoid penalties.


Whether you're temporarily in the U.S. or planning to settle long-term, planning early is the key to securing your financial future.
