Should You Contribute to a 401(k) After Moving to the US from India? A First-Timer’s Guide

"I'm on an H-1B and might move back to India in a few years. Is a 401(k) even worth it for me?"

This is the question we hear most from new arrivals. The short answer is usually yes, at least up to your employer's match. The full answer depends on your visa, your timeline, and where you plan to retire. Here is how to think it through.

Does your immigration status matter?

Less than you'd expect. H-1B, L-1, O-1, TN or green card, the plan generally doesn't ask. If your employer offers a 401(k) and you're an eligible employee, you can join.

Your status does affect how you're taxed. Once you meet the IRS substantial presence test, roughly a weighted count of 183 days in the US over three years, you're a US tax resident. That means US tax on your worldwide income, so your Indian accounts matter too. (IRS Publication 519 covers this in detail.)

Think about your timeline first

If you might leave the US: the 401(k) is not a trap, but cashing out early is expensive. Withdrawals before age 59½ are taxed as ordinary income, plus a 10% additional tax unless an exception applies. Moving abroad is not an exception. Plans also typically withhold about 20% for federal tax on cash-outs.

The better option is often to leave the money invested and withdraw it in retirement, wherever you live then. Many plans allow this once your balance is large enough.

Don't count on Social Security as a backup. You generally need 40 credits, about ten years of work, to qualify. The US has "totalization agreements" with some countries that let workers combine credits, but India is not on the SSA's list. If you leave before ten years, your Social Security taxes may buy no benefit. That makes the employer match more valuable.

Key features to know

• Automatic payroll deductions. The 2026 employee limit is $24,500.
• Employer match. Many employers add money when you contribute, often a percentage of your salary. This is the closest thing to free money in personal finance.
• Vesting. Your own contributions are always yours. Employer contributions may vest over several years, so check the schedule before a job change.
• Tax-deferred growth. You pay no tax on gains inside the account each year.
• Payroll taxes still apply. Contributions reduce income tax, not Social Security or Medicare tax.

How is it taxed?

With a traditional 401(k), contributions go in pre-tax, which lowers your federal taxable income now. Withdrawals are taxed as ordinary income later. State treatment varies.

Plan for two layers. The US taxes your withdrawals however you live. If you move back to India, how India treats the account depends on your residency status and the India-US tax treaty. Get cross-border advice before you withdraw anything.

Plan menu vs. self-directed

Most 401(k)s offer a plan menu, a curated list of funds chosen by your employer, usually including target-date funds that adjust automatically as you age. If you make no choice, your money often goes into one of these. It's simple and low-maintenance.

Some plans also offer a self-directed brokerage window, which lets you buy individual stocks, ETFs and a wider range of funds. You get more choice, but also more room for costly mistakes, and sometimes extra fees. For most new arrivals, the plan menu is plenty. Whichever you use, compare the expense ratios, the annual fund fees, because they compound over decades.

Roth or traditional?

Many plans offer a Roth 401(k). You contribute after-tax dollars, and qualified withdrawals (generally after age 59½ with the account open at least five years) come out tax-free. Unlike a Roth IRA, the IRS notes a Roth 401(k) has no income limit. You can also split contributions between Roth and traditional.

A rough rule: if your tax bracket is likely higher in retirement than today, Roth tends to win. If it's higher now, traditional often wins. Many new arrivals are early in their US careers with rising incomes, which is a point for Roth.

There is one cross-border caveat. The US tax-free treatment of a Roth may not be mirrored in India if you return. Confirm this with a professional before you build a large Roth balance you plan to carry back.

A simple starting plan

1. Contribute at least enough to get the full employer match.
2. Check the vesting schedule.
3. Choose a target-date fund or low-cost index funds.
4. Pick traditional, Roth or a split, based on your bracket and timeline.
5. Revisit everything when your status changes, such as a green card, a job change or a decision to return.
