If you return to India with a US 401(k), the short answer is this: during the RNOR period, foreign-source income (including 401(k)/IRA distributions) is generally not taxable in India; worldwide taxation begins only on becoming Resident and Ordinarily Resident (ROR). That makes the timing of withdrawals during the RNOR window one of the most valuable planning levers for returning NRIs — but the US penalty, US withholding and an unsettled treaty position mean "401k withdrawal NRI" decisions are never one-size-fits-all.
Step 1: know your Indian residential status first
Everything turns on whether you are Non-Resident, RNOR or ROR for the year of the distribution under Section 6. Use the Section 6 residential-status guide and the RNOR calculator to date your window, and read RNOR planning for how long the RNOR window returning NRI families can expect typically lasts.
401(k) tax returning to India: the RNOR window
During the RNOR period, foreign-source income (including 401(k)/IRA distributions) is generally not taxable in India; worldwide taxation begins only on becoming ROR. So distribution timing within the RNOR window is a core planning lever. After becoming ROR, the distribution is taxable in India on a worldwide basis, with foreign tax credit for US tax under Section 90/DTAA, claimed via Form 67 under Rule 128.
Section 89A 401k relief: deferring Indian tax until withdrawal
Section 89A (inserted by Finance Act 2021, effective AY 2022-23), with Rule 21AAA and Form 10-EE, lets a resident defer Indian tax on income accruing in a notified-country foreign retirement account until withdrawal — solving the accrual-vs-withdrawal mismatch that otherwise complicates foreign tax credit. The USA is a notified country (as are the UK and Canada). Form 10-EE must be filed on or before furnishing the ITR; the election is irrevocable and, if the person later becomes non-resident, is treated as never exercised. Eligibility: the account was opened while the person was non-resident in India and a resident of the notified country.
The US side: penalty, withholding and rollovers
A withdrawal before age 59½ generally attracts a 10% early-withdrawal penalty plus ordinary US income tax, and distributions to a non-resident alien are typically subject to US withholding (commonly around 30%, treaty-dependent). Rolling a 401(k) into an IRA does not itself trigger US tax, which can keep options open while you settle your Indian status. Any Indian tax saving from RNOR timing has to be weighed against that US cost.
Does the India-US DTAA solve double tax?
Do not assume it does. Whether a lump-sum 401(k) distribution qualifies as a pension or annuity under Article 20 of the India-US treaty is unsettled; periodic pension-style distributions have a stronger case than a lump sum. The treaty saving clause preserves the US right to tax its own citizens and residents, so treaty relief is fact-specific and should be confirmed before relying on it. See the India-US DTAA guide and how DTAA relief works for NRIs.
A practical sequence
Date your RNOR years; model a withdrawal inside versus after the window including the US penalty and withholding; check Section 89A eligibility before your first resident ITR; and keep US tax records for any Form 67 claim. Corridor detail is on the USA hub and the H-1B returnee hub, and the wider asset picture is in foreign retirement funds, RSUs and ESOPs.
