The RNOR window, and why the date you return decides how long it lasts

Short answer: a returning NRI usually passes through RNOR — resident, but not yet taxed as one. While it lasts, foreign income generally stays outside the Indian net. It runs on day counts from your preceding years, which means the date you arrive helps decide how long you get, and that date is the last thing still under your control.

What it is

Section 6 — unchanged in number under the Income-tax Act 2025 — sets residency. Within it sits a middle category: resident, but not ordinarily resident.

You reach it by being resident for the year, and then satisfying either:

• you were a non-resident in nine of the ten preceding years, or
• you were in India for 729 days or less across the seven preceding years.

Either test alone is enough. Most people returning after a long posting abroad satisfy both comfortably in their first year back, and then fall out of the status as the counts fill in behind them.

What it is worth

While RNOR, foreign income is broadly outside the Indian net — the main exception being income from a business controlled in India or a profession set up in India. Indian-source income is taxed exactly as it would be for anyone else.

For someone returning with a foreign brokerage account, overseas rental property, a foreign pension in payment, or deferred compensation still vesting, that is not a small distinction. It is often the largest single tax variable in the whole move.

Why the arrival date decides it

Residency turns on days present in the year. So the same person, returning in the same calendar period, can land in a different position depending on which side of a year boundary the arrival falls.

Two things move together:

• Which year becomes your first resident year, and
• How the preceding-year tests fall when measured from that year.

Where a large foreign receipt is expected — a bonus, a vesting tranche, a property sale abroad — the interaction between the receipt date and the arrival date is worth modelling before either is fixed. Moving an arrival by a few weeks is sometimes worth more than every deduction available for the year.

This is a genuinely time-limited piece of planning. Once you have landed, the count is what it is.

What it does not cover

Three things get assumed into RNOR that do not belong there:

• NRE interest does not stay exempt. That exemption is tied to being a person resident outside India, and a permanent return ends it. FCNR usually behaves better on the way back in — the account-by-account position is in NRE, NRO and FCNR.
• Disclosure is a separate question from taxability. Do not read "foreign income is not taxed" as "foreign assets need not be reported". Establish the disclosure position for your first resident year on its own footing, before the return is filed. Getting this wrong is expensive in a way the tax saving does not offset — and where an earlier resident year was already missed, FAST-DS 2026 is open until 31 December and settles it far more cheaply than the Black Money Act does.
• RNOR is not an election. You do not claim it or opt into it. It either applies on the day counts or it does not, which is why the computation matters more than the intention.

If you have already returned

The tests look backwards, so RNOR may still be running even if nobody worked it out at the time. The current year can still be taken correctly.

What cannot be undone easily is a year already filed on the wrong basis — either foreign income offered that need not have been, or foreign income omitted where the status had already lapsed. Both are worth finding early.

What to have ready

• Days present in India for each of the last seven financial years. Passport stamps are the usual source; be exact, because the tests are day counts and not approximations.
• The date of return you have in mind, and how much flexibility there is in it.
• Any large foreign receipt expected in the next two years, with its likely timing.
• A list of foreign assets and accounts held, for the disclosure question.
• Details of any business or profession you will continue to control from India, since that is the exception that pulls foreign income back into the net.

For how residency itself is determined, including the 120-day rule and deemed residency, see NRI taxation under the Income-tax Act 2025.

This is a working reference, not the statute. Residential status turns on your own day counts and should be computed against them before any decision is taken on it.
