Assuming you are in your late thirties, you spent six to twelve years on H-1B, your employer matched into a 401(k) that has been quietly compounding through two market cycles, and you are now booking the one-way flight home. The 401(k) is the single largest US-side line on your net worth, and it is also the asset most people leave on autopilot the longest after they return, because the plan portal still works and the statement still arrives.

The 401(k) does not automatically follow you. You have three live options on the day you stop being a US-tax resident — leave it with the plan, roll it to an IRA, or take a distribution — and each one carries a different tax bill in two countries plus a different operational headache for the next twenty years. The right choice depends less on the dollars in the account today and more on how long you expect to stay outside the US, what your Indian residency status looks like across the next two financial years, and how much custodian friction you are willing to tolerate.

1. The three options at a glance

Option              US tax now           India tax now         Long-run friction
Leave with plan     None                 None                  Plan rules; address; access
Rollover to IRA     None (direct)        None                  Custodian must serve NR clients
Take distribution   30% default NRA      RNOR: out of scope    None; account is closed
                    withhold + 10%       ROR: in scope w/ FTC
                    72(t) if under 59.5

No path is wrong by default. The framing that helps is: option one and two preserve the tax-deferred wrapper, option three breaks the wrapper to convert a US retirement asset into post-tax money in your hand. If you do not need the money in the next ten years, breaking the wrapper is almost always the most expensive of the three. If you do need it, the RNOR window is the cheapest year you will ever have to take it.

2. Option A — leave it with the plan

The simplest path, and for most returnees the right one in year one. The 401(k) stays with the current plan custodian, the balance keeps compounding inside the same fund choices, and you have to do nothing on the day you land in India beyond updating your address.

A few mechanics matter:

  • Force-out floor. Under IRC Section 401(a)(31)(B)(ii) as amended by the SECURE 2.0 Act, plans may cash out or force-roll former-employee balances of seven thousand dollars or less without your consent (raised from five thousand effective 2024). Above that threshold, the plan generally cannot involuntarily cash out the balance without your consent. If your balance is close to the floor and you do not want a surprise check in the mail, roll to an IRA before you leave.
  • Address and beneficiary changes from outside the US. Some plans freeze beneficiary updates, address changes, or new investment elections for former employees with foreign addresses. Fidelity and Vanguard generally allow it; smaller third-party administrators sometimes do not. Confirm in writing before you fly.
  • Required Minimum Distributions. Under the SECURE 2.0 Act / IRC Section 401(a)(9), the RMD start age is seventy-three for individuals born 1951–1959 and rises to seventy-five for those born in 1960 or later. For most readers of this article (late thirties to forties today), the present-law schedule is seventy-five unless Congress changes it again. If you leave the 401(k) untouched and reach the RMD age while still in India, you will start receiving mandatory distributions that are US-source and trigger the cross-border analysis in section four below.
  • No new contributions. You are no longer an employee, so the contribution route is closed. The balance compounds on its own.

The hidden cost of this path is that you now have a US asset that you cannot easily service. If your custodian later restricts non-US-resident accounts (this has happened in waves across firms), you may be forced into option B or C on the custodian's timeline rather than yours.

3. Option B — roll over to an IRA

A direct trustee-to-trustee rollover from a 401(k) to a Traditional IRA is not a US taxable event and not an India taxable event, because nothing was distributed to you. The wrapper changes; the tax-deferred status does not.

Why returnees do this:

Wider fund menu          Plan menus are narrow; IRAs open the full fund universe
Consolidation            Multiple old 401(k)s collapse into one IRA balance
Service flexibility      IRAs are easier to manage from abroad than employer plans
Estate planning          IRA beneficiary mechanics are cleaner cross-border
Roth conversion runway   Traditional IRA can be converted to Roth in low-income years

The complication is custodian residency rules. Several large brokerages (Vanguard most prominently) have restricted account-opening and trading for non-US-resident clients in recent years. Fidelity, Schwab, and Interactive Brokers have continued to serve former-US residents in many countries, but the policy is firm-specific, country-specific, and changes without notice. If you plan to roll to an IRA, open and fund the IRA while you are still a US resident with a US address, complete the rollover, and then update the address — not the other way around.

A subtle planning move: the Traditional-to-Roth conversion. During RNOR years your Indian tax on a Roth conversion is zero (foreign-source income, outside scope). Your US tax on the conversion is ordinary income, with the IRA custodian typically withholding at the default thirty per cent NRA rate unless treaty documentation is accepted; whether any treaty reduction actually applies to a deemed-distribution conversion is position-specific and not a clean question. Whether the math works depends on your projected ROR-year marginal rate in India when you would otherwise have withdrawn. For most returnees the conversion is not a slam dunk and needs an actual cross-border CA running the projection. Do not do it on a thumb rule.

4. Option C — take a distribution

You can take a full or partial distribution at any time, subject to plan rules. The tax stack on the US side, for a non-resident alien:

Default NRA withhold    30% of gross distribution under IRC Chapter 3 /
                        Section 1441 (NRA withholding regime)
Treaty reduction        India-US DTAA Article 20 (pensions) and Article 23
                        (other income) govern the analysis. There is no
                        single fixed treaty percentage that applies to all
                        401(k) distributions — periodic versus lump-sum and
                        private pension versus annuity all matter. Confirm
                        the specific treaty position with a cross-border
                        CA and the plan administrator before assuming any
                        reduction below 30%.
Early-withdrawal tax    Additional 10% under IRC Section 72(t) if under 59.5.
                        Exceptions: SEPP, disability, death, others — narrow.

Form W-8BEN must be on file with the plan administrator before the distribution. Indian PAN goes on the Foreign TIN line; treaty-claim country and the relevant article are entered in the treaty-benefits section. PAN on the form is necessary but not sufficient — the withholding agent still has to accept the treaty claim, and many large custodians default to the full thirty per cent rate and require you to reclaim the difference by filing Form 1040-NR after year-end.

On the India side, the same dollar is treated as follows:

  • If you are RNOR in the year of receipt: foreign-source pension income is outside the scope of Indian tax under the proviso to Section 5(1) read with Section 6(6) of the Income-tax Act, 1961. The US tax paid is your final tax on that dollar; there is nothing to claim in India because there is nothing to tax.
  • If you are ROR in the year of receipt: the gross distribution is part of your global income. You pay Indian tax at your slab rate on the gross, and you claim a Foreign Tax Credit for the US tax paid (the actual treaty-reduced or default Chapter 3 withhold; the FTC eligibility of the Section 72(t) additional tax is debated and position-specific, so verify with your CA). FTC mechanics are in Rule 128 of the Income-tax Rules and require Form 67. Under the post-2022 amendment to Rule 128(9) (CBDT Notification 100/2022), Form 67 may be filed up to the end of the relevant assessment year when the return is filed under Section 139(1) or 139(4).

The single biggest planning lever a returnee has on a 401(k) is the residency status in the year of distribution. A large lump-sum taken in a confirmed RNOR year is taxed only by the US. The same lump sum in an ROR year is taxed by both, with FTC offsetting most of the US bill — but Indian slab rates can be higher than the treaty-reduced US rate, leaving you with a real top-up bill in India.

5. The RNOR-window arithmetic

The RNOR window is often about two financial years for someone returning after a long US stint (the exact duration is fact-specific and depends on the timing of return and how the prior-year tests run), assuming you were non-resident in nine of the ten prior previous years (Section 6(6)(a)) or were in India for seven hundred and twenty-nine days or less in the prior seven previous years (Section 6(6)(b)). During those years, a 401(k) distribution looks like this:

                       Year 1 (RNOR)        Year 3 (ROR)
Distribution           $50,000              $50,000
US withhold (30%)      $15,000              $15,000
US 72(t) (if <59.5)    $5,000               $5,000
India tax              0                    Slab on gross w/ FTC
Net India top-up       0                    Slab% × $50k − $15,000 FTC

For a forty-five-year-old in the thirty per cent Indian slab, the same fifty-thousand-dollar distribution costs roughly twenty thousand dollars in year one (thirty per cent withhold plus the Section 72(t) additional tax) and a similar total in year three (Indian tax of fifteen thousand on the gross, largely offset by the FTC of fifteen thousand, plus the same US Section 72(t) bill). The RNOR-window advantage actually widens when a valid treaty claim reduces the US withhold (the year-one bill drops while year-three loses some FTC offset), and narrows when no treaty reduction applies and the Indian slab rate is close to the default US Chapter 3 rate.

Two practical reads:

  • If you need a chunk of the 401(k) for the down-payment, the school fees, or to close out a US balance entirely, take it in a confirmed RNOR year.
  • If you do not need it, do not pull it during RNOR just to "use the window." The tax-deferred wrapper is more valuable than the one-time RNOR shield if your time horizon is more than ten years.

6. Roth 401(k) and Roth IRA — separate animals

If part of your balance is a Roth 401(k) or you have a separate Roth IRA, the analysis changes:

  • US side. Qualified Roth distributions (account held five years and age fifty-nine and a half) are tax-free. Non-qualified distributions can have an earnings portion taxed at ordinary rates.
  • India side. This is the contested zone. The DTAA's pension article (Article 20) addresses pensions and similar remuneration, and the protocol-and-MoU stack around it has long been read by some practitioners to extend treaty-style treatment to Roth distributions — but the Income-tax Act does not have a domestic exemption for foreign Roth distributions, and the Central Board of Direct Taxes has not issued a clean clarification. The practical position taken by most cross-border CAs is that during RNOR years a Roth distribution is outside scope on the same Section 5/6(6) basis as any other foreign-source income, and during ROR years the safe assumption is that the earnings portion is taxable in India with FTC — the principal portion of a Roth contribution being post-tax in the US does not automatically translate to post-tax in India. This one genuinely needs a CA looking at your specific Roth basis records.

7. The decision in one paragraph

For most returnees with no immediate need for the money, the path of least regret is: roll the 401(k) to a Traditional IRA at a custodian that explicitly serves non-US-resident clients, do this before you change your US address, leave it invested, and revisit at the end of each RNOR year whether a partial distribution makes sense. Do not take a full lump-sum in RNOR year one just because the tax is zero in India; the wrapper is worth more than the shield over a twenty-year horizon. Do not leave it with the original plan if the plan restricts non-resident service or if the balance is near the seven-thousand-dollar force-out floor. And do not run the W-8BEN, the treaty claim, the FTC filing, and Form 67 on intuition — these are mechanical, deadline-driven steps and every one of them has caught returnees out at least once.
