401(k), IRA and HSA: America's Three Wealth Machines, Explained
7 min read · Updated July 12, 2026
These three account types are how American salaries quietly become wealth — and visa holders can use all of them fully. What newcomers need beyond the basics: the employer-match math, the visa-specific questions, and what happens to these accounts if you ever leave America.
What each account is
401(k): the employer-sponsored retirement plan. Contributions come from payroll pre-tax (traditional) or post-tax (Roth 401(k)); annual limits are set by the IRS and published each year. The headline feature is the employer match — free compensation contingent only on your contributing; note the vesting schedule that determines when matched money becomes irrevocably yours.
IRA: the retirement account you open yourself at any brokerage — traditional (deduction rules depend on income and workplace-plan coverage) or Roth (direct contributions phase out at higher incomes; growth and qualified withdrawals are tax-free). Its power for immigrants: it follows you across employers without paperwork.
HSA: available only alongside a qualifying high-deductible health plan, and uniquely triple-advantaged — deductible going in, growth untaxed, and untaxed coming out for qualified medical expenses, with no use-it-or-lose-it (that's the FSA). After 65 it behaves like a retirement account for any purpose.
Visa-holder specifics
Eligibility: immigration status is irrelevant to participation — taxable US compensation plus an employer plan (or any earned income, for IRAs) is what matters. H-1B, L-1, F-1 on OPT: all routinely participate and receive matches.
The Roth question has an emigrant's angle: traditional contributions bet your future tax rate will be lower; Roth bets it will be higher or that you value tax-free flexibility. Expected years in the US, green-card odds and India-return plans all feed this — it's a personal-model question, not a universal answer, and the honest move is running both scenarios.
If you leave America
The accounts remain yours from India — brokerages have non-resident procedures (some restrict trading; none confiscate). Options: leave invested until retirement age, roll a 401(k) into an IRA for control, or withdraw — early withdrawal generally costs income tax plus a 10% penalty, and as a nonresident, US withholding and treaty rules apply on distributions.
The India side adds a layer: Indian taxation of foreign retirement accounts has its own provisions (including a section allowing deferral alignment for notified countries, the US among them). This intersection — US distribution rules, treaty articles, Indian residency phase-in — is precisely where one cross-border CPA consultation before repatriating pays for itself many times over.
