Roth IRA vs 401k for H1B Holders — Which One First in 2026?

Watch the full video

Even if you eventually return to India, a Roth IRA keeps growing tax-free for life. Most H1Bs ignore it because the 401k match is shiny. Here's the right priority order.

Key takeaways

• Priority order: 401k match → HSA → Roth IRA → 401k max → taxable brokerage
• Roth IRA direct contributions phase out above an IRS income (MAGI) threshold — most H1Bs on typical salaries still qualify; check the current thresholds on irs.gov
• Backdoor Roth available if you earn over the limit
• If you return to India: Roth IRA continues growing tax-free, US won't tax withdrawal at 59.5+
• Open at a major broker (Fidelity, Schwab, Vanguard) — all support H1B holders; if you may leave the US later, confirm the broker's non-resident policy first

The H1B retirement priority order

For most H1Bs earning $80K-$200K, fund accounts in this exact order:

1. 401k up to employer match. Free money. Always max the match first.
2. HSA if you have a high-deductible health plan. Triple tax advantage.
3. Roth IRA — $7,500/year (2026 limit). Tax-free growth forever.
4. 401k beyond match up to the $24,500 employee limit (2026).
5. Taxable brokerage for anything beyond.

What if you return to India?

Three scenarios for your retirement accounts:

Backdoor Roth for high earners

If you earn over the Roth IRA income phase-out for your filing status, you can still contribute via the backdoor Roth:

1. Contribute the annual IRA limit ($7,500 for 2026) to a Traditional IRA (non-deductible).
2. Convert that Traditional IRA to a Roth IRA immediately (within days).
3. Pay tax only on any growth between contribution and conversion (usually $0).

How to decide: 401k-first or Roth-first?

After the employer match, the real question is where your next dollar goes: extra 401k or Roth IRA. Your visa timeline decides it more than your tax bracket does.

Put the next dollar in the Roth IRA if:

• You're not sure you'll stay in the US. Roth withdrawals at 59.5+ are US-tax-free even if you've moved back to India. A bigger pre-tax 401k means a bigger future tax bill on every withdrawal.
• Your income is under the Roth IRA phase-out for your filing status. You can contribute directly, no paperwork. Once you cross the limit, the same $7,500 requires the backdoor two-step and Form 8606.
• You're early in your career. You're taxed at a lower rate today than you will be later — exactly when paying tax upfront (Roth) is cheapest.
• You want an escape hatch. Roth IRA contributions (not earnings) can be withdrawn anytime without US tax or penalty; a 401k locks money up until 59.5.

Push more into the 401k instead if:

• You're at the top of the $80K–$200K band and staying long-term. The pre-tax deduction saves tax at your highest marginal rate today; you have decades for the deferral to compound.
• Your plan has strong low-cost index funds. The 401k's $24,500 limit dwarfs the IRA's $7,500 — if the funds are good, the extra room matters.
• You plan to use the RNOR window. A pre-tax deduction now plus a lower-tax withdrawal during India's RNOR period (typically 2-3 years) can be a strong combination — but how RNOR treats US retirement distributions is contested among cross-border CPAs, so confirm the treatment for your facts before relying on it.

Worked example: $80K vs $200K salary

The page's priority order — match → HSA → Roth IRA → 401k max — plays out very differently at the two ends of the typical H1B salary band. Run the numbers:

The full employee-side stack is $24,500 (401k) + $7,500 (Roth IRA) = $32,000 a year — 16% of gross at $200K, but 40% at $80K, which almost nobody sustains while paying rent and sending money home. So the $80K earner follows the order, captures the match plus the full $7,500 Roth — the two highest-value dollars available — and stops there. Roth space for a given tax year expires at that year's tax-filing deadline: you cannot go back and fill a missed year. (The separate, much higher combined 401k limit, which includes employer money, matters mainly at the $200K end.)

Leaving the US? Do this with your 401k, step by step

Your 401k and IRA do not close when your H1B ends. Immigration status and account ownership are separate — the money stays yours and keeps growing. What changes is logistics. Do these before your flight, not after:

1. Do not cash out. A withdrawal before 59.5 triggers US ordinary income tax plus an early-withdrawal penalty, and the plan withholds part of it before you see a cent. You trade decades of compounding for an immediate tax bill.
2. Roll the 401k into a Traditional IRA while you still have a US address. Large brokers such as Fidelity and Schwab have historically been more open to non-resident clients than many employer plans and smaller brokers — but policies vary by country and account type and change over time, so confirm with the broker before you leave. Moving accounts from abroad is far harder.
3. Fix your login before you lose your US phone number. Move two-factor authentication to an authenticator app or an international number — getting locked out of a six-figure account from abroad is a months-long support ordeal.
4. Update your address and tax status. As a non-resident, the broker needs Form W-8BEN on file instead of a W-9, so withholding on distributions follows the US-India treaty rather than default rates.
5. Keep the Roth IRA open. You can't add money without US earned income, but the balance keeps compounding and withdrawals at 59.5+ stay US-tax-free. India taxes the growth under its own rules — time withdrawals with a cross-border CPA.
6. Map withdrawals to the RNOR window. The RNOR period after returning to India (typically 2-3 years) may be the lowest-tax window for 401k/Traditional IRA distributions — but how RNOR treats US retirement money is genuinely contested among cross-border CPAs and depends on your facts, so confirm the treatment before relying on the timing.

Common mistakes that cost real money

Five errors that show up repeatedly — each with a specific dollar consequence:

• Cashing out the 401k on the way out of the US. The most expensive mistake here. Income tax plus the early-withdrawal penalty eat a large slice of the balance immediately, and you forfeit every year of future tax-deferred growth. Roll it to an IRA and leave it instead.
• Stopping at the employer match. The match is step one, not the finish line. Every year you skip the Roth IRA, $7,500 of permanent tax-free space disappears — contribution room does not carry forward.
• Contributing directly to a Roth IRA while over the income limit. Above the IRS MAGI phase-out for your filing status (check the current year's thresholds on irs.gov), the IRS charges an excise tax on the excess every year until you fix it. High earners must use the backdoor route.
• Doing a backdoor Roth with an existing pre-tax IRA balance. The pro-rata rule treats all your Traditional IRA money as one pot, so part of the conversion becomes taxable. Roll pre-tax IRA balances into your 401k first, then do the backdoor clean.
• Skipping Form 8606. This form tells the IRS your backdoor contribution was already-taxed money. Miss it and the default assumption is the whole conversion is taxable — tax on the same $7,500 twice.
