Assuming you've been an NRI for the last 9–15 years and you're thinking about moving back to India in the next 12–18 months. Before you book the one-way ticket, there is a status the Income Tax Act gives you for a year or two after you land. It is called RNOR — Resident but Not Ordinarily Resident.
While you are RNOR, your foreign income (US salary, US brokerage gains, dividends from a US ETF, rent from a flat in Singapore) generally stays outside the Indian tax net. One qualifier worth knowing: the Section 5 proviso still pulls in foreign income that is derived from a business controlled in or a profession set up in India, and any income actually received in India is taxable. Once you cross over to ROR — Resident and Ordinarily Resident — your worldwide income becomes taxable here.
Most people find out about RNOR in the second year, after they've already paid tax they didn't owe. That is the gap RebaseNest closes.
1. The two tests that decide RNOR
Section 6(6) gives you RNOR status if either of the following is true for the FY you become a resident:
Test A You were a Non-Resident in 9 out of the 10 previous FYs.
Test B Your total stay in India over the last 7 FYs was 729 days or fewer.
For the typical returnee, passing either Test A or Test B gets you RNOR; failing both lands you in ROR from day one. (The two extra limbs added in 2020, clauses (c) and (d), can also produce RNOR in narrower cases — covered below.) The tests are evaluated fresh every year, so you can be RNOR in FY26-27 and ROR in FY27-28.
Post Finance Act 2020, §6(6) also has two more limbs worth flagging: clause (c) treats a high-income visiting Indian citizen / PIO (the 120-181 day case under Explanation 1(b)) as RNOR, and clause (d) does the same for a "deemed resident" under §6(1A) — a stateless Indian citizen with Indian income above ₹15L who isn't taxable in any other country. For the typical returnee, Tests A and B are the ones that decide the outcome.
The trap: the calculation needs your day count for each of the last 7 financial years, not just the recent two. People remember last year and the year before. The 4th, 5th, 6th year ago, that is where the math breaks.
2. What the RebaseNest day-counter actually does
You enter your day count for each of the last 7 FYs. The tool runs the checks in parallel:
- §6(1)(a) — were you in India for 182 days this FY?
- §6(1)(c) + Explanation 1 to §6(1) — were you here for 60 days this FY and 365 days across the last 4? Explanation 1(a) widens the 60-day floor to 182 for an Indian citizen who leaves India for the purposes of employment outside India. Explanation 1(b) widens it to 182 for an Indian citizen / person of Indian origin (PIO) who is outside India and comes on a visit to India, but only to 120 (Finance Act 2020) if their Indian-source income exceeds ₹15 lakh.
- §6(6) Test A and Test B — both run. We tell you which test you passed and how close the other was.
Output is a plain status line:
FY 2026-27 Resident RNOR via §6(6) Test B (724/729 days)
FY 2027-28 Resident RNOR via §6(6) Test A (9/10 NR years)
FY 2028-29 Resident ROR
You also see the raw counts that drove each decision. No black box.
3. Why the day counts matter in rupees
Take a typical case. You return July 2026 with 50,000 USD of long-term capital gains sitting in your US brokerage and 80,000 USD of W-2 income for the part of the year you worked in the US.
If you are RNOR for FY26-27 and FY27-28, that 130,000 USD generally sits outside the Indian net (subject to the Section 5 proviso above). If the calculator gets the day count wrong and flags you ROR from day one, you owe Indian tax on the global income, claim DTAA credit for US tax paid, and end up with a refund fight that drags 18 months.
The cash-flow swing can run into tens of lakhs over the two RNOR years. The exact number depends on FX, old vs new slab regime, the character of the US gains, US federal and state tax already paid, and how the foreign tax credit mechanics land. To each on their own — run your own numbers before you plan around it.
4. The edge case nobody talks about — Explanation 1
Explanation 1 to §6(1) is two separate clauses, and the difference matters:
- 1(a) covers an Indian citizen leaving India for employment abroad. The 60-day floor becomes 182 in the FY of departure. This is the outbound case.
- 1(b) covers an Indian citizen / PIO who is outside India and comes on a visit. 60-day floor becomes 182, or 120 if Indian-source income crosses ₹15 lakh.
For someone making a permanent move back to India, neither clause is an automatic shield. 1(a) is about leaving India, not arriving. 1(b) only helps if the stay genuinely qualifies as a "visit", which a one-way return usually isn't. We flag this honestly in the tool rather than auto-applying the carve-out.
Several popular online calculators we tested handle Explanation 1 inconsistently — some skip the 120-day FA2020 sub-rule, some assume it applies to every returnee. We surface the exact clause that fired so you can verify it with your CA.
5. How to use it
- Open RebaseNest → Compliance panel.
- Enter days-in-India for each of the last 7 FYs. (Passport stamps, US I-94, or Indian eFRRO travel history all work.)
- Pick your person category (Indian citizen, person of Indian origin, foreign national; OCI cardholders pick PIO for the statutory test) and flag the trip type (visit vs permanent return).
- The tool returns this FY status plus a 3-year forward projection if you stick to your planned return date.
You can also run two scenarios side-by-side (return June 2026 vs return January 2027) and see which gives you more RNOR years before you commit.
6. The thumb rule
If you've been outside India for 9+ FYs straight, you almost certainly clear Test A and get two full years of RNOR. If your US-India travel has been heavy (4+ trips home a year, 3-week stays each), Test B can fail by 50–80 days and you might only get one RNOR year.
A January return can give you a clean partial FY of NR before the RNOR years kick in, but only if the 60+365 prior-four-year test isn't already met for that FY, and only if Explanation 1(b) "visit" treatment genuinely applies. For a permanent move, don't assume January automatically buys an extra NR year. Run both dates in the tool.
7. What this is not
- Not tax filing software. You still need a CA to file your ITR.
- Not legal advice. Edge cases (seafarers under Explanation 2 / Rule 126, students, dual-residency tie-breakers) need a tax practitioner.
- Not a guarantee. The tool surfaces the math; you confirm the day counts against your passport.
What it is: an honest calculator that shows its working.
