The RNOR window: how returning NRIs can realise US gains tax-free before it closes

Most returning NRIs plan their financial move carefully — converting NRE accounts, deciding what to do with the 401k, figuring out RSU tax. Fewer recognise that the first 2–3 years after return are a genuinely rare tax planning window that, once closed, doesn't reopen.

That window is RNOR status.

What RNOR actually means for foreign income

When you return to India and become tax-resident, you don't immediately become a Resident and Ordinarily Resident (ROR) — the status that triggers worldwide income taxation. First, you pass through RNOR (Resident but Not Ordinarily Resident), which applies as long as:

• You were a non-resident for 9 of the last 10 financial years, or
• You were present in India for less than 729 days in the last 7 financial years

Most NRIs returning after 5+ years abroad qualify for 2–3 RNOR years.

The RNOR rule on foreign income: income that accrues or arises outside India, and is not derived from a business or profession controlled from India, is completely exempt from Indian income tax.

This is not a deduction or a credit. It's an exemption — Indian tax on that income is zero.

What this means in practice

The planning opportunity

1. Concentrated US stock positions

Many returning NRIs arrive with concentrated positions — employer stock accumulated over years of RSU vesting, or a tech portfolio that's grown 5–10x. These are the positions you were probably going to diversify out of anyway.

Selling during RNOR: zero Indian tax on the gain. US tax treatment depends on your US residency status at sale (most returning NRIs who are not US citizens or green card holders are not subject to US capital gains tax on equity sales as non-resident aliens — verify with a US tax advisor).

Selling after RNOR: 12.5% Indian LTCG on the same gain, with a DTAA credit for US tax paid.

The decision is not "should I sell everything during RNOR." It's: which positions were you planning to exit or rebalance out of regardless of tax? Those, do during RNOR.

2. 401k distributions and Roth conversions

This is the highest-leverage use of the RNOR window for people with large retirement account balances.

Traditional 401k / IRA distributions: taxable as US income (US withholding applies). During RNOR, zero Indian tax. After RNOR, India taxes distributions at your slab rate, minus DTAA credit for US tax already paid.

Roth IRA conversions: you convert pre-tax 401k or Traditional IRA money to Roth, paying US income tax on the converted amount now. During RNOR, the Indian side is zero. After converting to Roth, future withdrawals (post-59½) are US-tax-free. This is a one-time window: the combination of RNOR (zero Indian tax on conversion) + Roth (zero US tax on future withdrawals) is available only while RNOR lasts.

The conversion math: if you're converting ₹1 crore equivalent (~$120,000) and your marginal US rate on that amount is 22%, you pay ~$26,000 in US tax. No Indian tax during RNOR. After conversion, that money grows and withdraws tax-free. Compare this to leaving it in Traditional: when you withdraw post-RNOR, India taxes it at 30% (above ₹15L) minus whatever US credit you get — you likely owe something to India.

3. RSU vesting schedule optimisation

If you have unvested RSUs from a US employer and you're joining an Indian subsidiary or starting fresh in India, your vesting schedule matters:

• RSUs vesting while you're still employed by the US entity (foreign employer) during RNOR: exempt from Indian tax
• RSUs vesting from an Indian employer: taxable as salary in India regardless of RNOR

If you have flexibility in your employment structure or are negotiating a return package, the RNOR window is worth factoring into when equity-heavy compensation vests.

The trap: waiting too long

This is the most common mistake. Returning NRIs arrive, get busy settling in, and defer decisions on their US portfolio. They know they should "deal with it at some point." Two years pass. They become ROR. Now those same positions carry Indian tax on sale.

The RNOR window doesn't extend. It doesn't pause. It runs from when you become Indian tax-resident (typically the financial year you cross 182 days in India), and it runs for however many years your NRI history entitles you to.

What to do in Year 1:

1. Calculate your RNOR years remaining — count your India days over the last 10 financial years
2. List all foreign assets with unrealised gains (US brokerage, RSUs, 401k/IRA)
3. For each: decide "would I exit this in the next 5 years anyway?"
4. If yes: model the tax savings of doing it during RNOR vs after
5. Consult a CA familiar with India-US DTAA and cross-border tax before executing large transactions

What RNOR does not exempt

To be precise about the limits:

• Indian-source income is always taxable — salary from an Indian employer, Indian rental income, interest on Indian bank accounts (including NRO, once you're resident), Indian equity gains
• Foreign income from India-controlled business: if you're running a startup from India for a foreign entity and the business is effectively controlled from India, that income may be considered India-sourced
• DTAA disclosure is still required: even with zero Indian tax during RNOR, you must disclose all foreign income in Schedule FSI (Foreign Source Income) of your ITR-2, and all foreign assets in Schedule FA — the exemption is from tax, not from reporting

The numbers

To make this concrete: an NRI returning in April 2026 with:

• ₹2 crore in US brokerage (unrealised gain of ₹80 lakh)
• $200,000 in a Traditional 401k
• ₹50 lakh in unvested RSUs (foreign employer)

If they act during RNOR:

• Sell brokerage: ₹0 Indian tax on ₹80 lakh gain
• Convert $100,000 of 401k to Roth: ₹0 Indian tax (pay ~22% US tax)
• RSUs vest: ₹0 Indian tax on ₹50 lakh

If they wait until ROR:

• Same brokerage sale: ₹10 lakh Indian LTCG (12.5% of ₹80 lakh)
• Same 401k withdrawal: India taxes at 30% slab minus DTAA credit
• RSU vest as Indian salary: 30% + surcharge on ₹50 lakh = ~₹15–17 lakh tax

The RNOR window, used well, is worth ₹25–40+ lakh in avoided Indian tax for a typical senior tech professional returning from the US.

Getting the documentation right

The RNOR window is valuable — but it only works if your tax filings are correct. The exemption requires:

• Accurate determination of your RNOR start date (based on your India day count history)
• Schedule FSI filed correctly for every foreign income item
• Schedule FA showing all foreign assets as of December 31
• Form 67 filed before your ITR if you're claiming DTAA credits on US tax paid

Errors in any of these can cost you the exemption or trigger scrutiny. Rovia can help with cross-border tax documentation — RNOR status letters, Schedule FA preparation, and Form 67 for DTAA credits, coordinated with your US tax filing.
