When a long-stay NRI talks about delaying the move back to India, the talk tends to stay on the India-side clock: residency under Section 6, the RNOR window, FEMA status, account redesignation. Those clocks are real, and they are the subject of a separate piece on this site. They are also not the only clocks.

In parallel, a second ladder of year-thresholds has been counting on the US side. It does not care about the emotional reasons for staying. It also does not reset on the day a plane lifts off from JFK. The longer the stay, the more rungs that ladder accumulates. Knowing what each rung is, and which one is currently relevant, is the part of the conversation that tends to get skipped in NRI groups.

This is a primary-source explainer on the four US-side year-thresholds that matter most for long-stay Indian-origin residents: the Substantial Presence Test, the green-card residency-end rules, the 8-of-15 long-term-resident definition, and the US estate-tax domicile concept. None of this is advice. Each rung points to a different conversation with a US-licensed adviser.

1. The Substantial Presence Test: the US tax-residency day count

Under IRC §7701(b)(3), a non-US citizen who is not a lawful permanent resident is a US resident alien for tax purposes if present in the United States for at least 31 days in the current calendar year and at least 183 weighted days under the three-year formula. The formula:

Current calendar year days        x   1
First preceding year days         x   1/3
Second preceding year days        x   1/6
Sum >= 183 days                   =>   US resident alien for tax purposes

The "closer connection" exception in IRC §7701(b)(3)(B), filed on Form 8840, can rebut the test for a person present fewer than 183 days in the current year who maintains a tax home in a foreign country and a closer connection there. The exempt-individual rules in IRC §7701(b)(5) carve out separate categories. Students temporarily present on F, J, M, or Q visas generally exclude days for up to 5 calendar years. Teachers and trainees on J or Q visas generally are not exempt if they were exempt as a teacher, trainee, or student in any part of 2 of the 6 preceding calendar years. Once the SPT is met, US worldwide income is in scope under IRC §61, subject to treaty provisions, and no election is required to become a resident alien.

2. The green-card lawful-permanent-resident clock: starts and ends are separate questions

A lawful permanent resident is a US tax resident under IRC §7701(b)(1)(A)(i) for any calendar year in which the LPR status is in force at any time. The status starts on the day of admission as an immigrant. It ends, for US tax purposes, on the earliest of three events listed in IRC §7701(b)(6): the immigration status is revoked; the LPR has been judicially or administratively determined to have abandoned the status; or the LPR commences to be treated as a resident of a foreign country under a tax treaty between the United States and that foreign country, does not waive the benefits of the treaty, and notifies the Internal Revenue Service of that treatment.

Two consequences worth noting in plain language. A returnee who lands in India but does not formally abandon the green card (via Form I-407, lodged with USCIS or at a US embassy/consulate per the relevant USCIS instructions) is still a US tax resident in US domestic-law terms. A returnee who triggers the DTAA tie-breaker in Article 4 of the India-US treaty and notifies the IRS may end US tax residency under §7701(b)(6)(B). This notification is itself a reportable event under the IRC §877A regime if the LPR meets the long-term-resident definition (see Section 3 below).

The "easier to keep it just in case" reflex is widely held and not always neutral on tax. The longer the LPR clock has been running, the more downstream rungs it has lit up.

3. The 8-of-15 long-term-resident rule and the IRC §877A exit-tax regime

IRC §877A is the exit-tax regime that applies to "covered expatriates." For a green-card holder, the gating definition is "long-term resident" in IRC §877(e)(2): an individual who has been a lawful permanent resident of the United States in at least 8 taxable years during the period of 15 taxable years ending with the tax year that includes the expatriation date.

A year in which the individual is treated as a resident of a foreign country under a tax treaty and does not waive the treaty benefits is not counted toward the 8-year total. The mechanics matter: a returnee who triggers the India-US DTAA tie-breaker in Article 4 in a specific year may exclude that year from the 8-year count, but the prior unbroken green-card years still count.

A long-term resident who expatriates and meets any one of the "covered expatriate" tests incorporated by IRC §877A(g)(1) from IRC §877(a)(2) (the net-income-tax test, the net-worth test of USD 2 million, or the certification test (failure to certify five years of US tax compliance on Form 8854)) is subject to the mark-to-market exit-tax on most worldwide property under IRC §877A, with the exclusion amount indexed annually for inflation. For calendar year 2025, the §877(a)(2)(A) average-annual-net-income-tax threshold is USD 206,000 and the §877A(a)(3) exclusion amount is USD 890,000 (IRS Rev. Proc. 2024-40). For calendar year 2026, those figures are USD 211,000 and USD 910,000 respectively (IRS Rev. Proc. 2025-32).

The thresholds and the indexed exclusion change. The 8-year limb is the structural piece that does not.

4. US estate-tax domicile: a domicile test, not a day-count test

The US transfer-tax system has a separate residency concept for estate and gift tax. Under 26 CFR §20.0-1(b)(1), a person is a US resident for estate-tax purposes if domiciled in the United States at the time of death; domicile is acquired by living, even for a brief period, in a place with no definite present intention of later removing therefrom. The contrast with the income-tax SPT is intentional: estate-tax residency turns on intent and physical presence with intent, not on a weighted day-count.

The economic gap between US-domiciled and non-US-domiciled status is material. A US-domiciled decedent's worldwide estate is subject to US estate-tax, with the IRC §2010 basic exclusion amount set at USD 13,990,000 for decedents dying in 2025 (IRS Rev. Proc. 2024-40) and USD 15,000,000 for decedents dying in 2026 (IRS Rev. Proc. 2025-32, reflecting the 2025 amendment to §2010). A nonresident not a citizen of the United States is generally subject to US estate-tax on US-situated assets only; Form 706-NA is generally required if US-situated assets exceed USD 60,000, and IRC §2102(b)(1) allows a USD 13,000 unified credit against the §2101 tax.

The India-US estate-tax position is unusual: India does not currently impose an estate-tax (the Estate Duty Act, 1953 was abolished in 1985), and India and the United States do not have an estate-tax treaty. A long-stay NRI who becomes US-domiciled accumulates US estate-tax exposure on worldwide assets that India would not separately tax, with no treaty-relief mechanism between the two countries on this head.

5. Putting the four clocks on one timeline

Schematically, for a long-stay NRI who arrived on an F-1, moved to H-1B, and later to LPR:

Year 0    F-1 arrival; SPT clock paused (exempt-individual)
Year 5    F-1 exempt-individual window ends; SPT begins to count
Year 6+   SPT met in most years; US worldwide-income tax under IRC §61
Year X    LPR adjustment; §7701(b)(1)(A)(i) overrides SPT
Year X+8  Long-term-resident definition in IRC §877(e)(2) is now satisfied;
          IRC §877A exit-tax regime applies on any future expatriation if
          the covered-expatriate test in IRC §877(a)(2) is met
Throughout   US estate-tax domicile question runs in parallel, on intent
             plus residence, not day-count (26 CFR §20.0-1(b))

The chart is structural, not a forecast. The relevant rung on any individual's ladder is a function of visa history, LPR start date, and the specific years for which a treaty position was claimed.

6. Six pre-return checks on the US side, mirroring the India-side checklist

These are educational reference items, not advice. The mirror of the India-side checklist on the returnee structural checklist is a short list:

  1. SPT history. Compiling US presence days for the last three calendar years per the IRC §7701(b)(3) weighted formula reveals US resident-alien status for each year on the record.
  2. LPR clock length. The number of tax years during which lawful-permanent-resident status was in force is the input to the IRC §877(e)(2) long-term-resident test.
  3. Form 8854 trigger awareness. Form 8854 is filed by expatriates (including long-term residents who end US tax residency) to certify compliance with US tax obligations for the 5 tax years before expatriation and to satisfy the information-reporting rules in IRC §6039G. Tracking that the form will be in scope is part of any LPR-abandonment reading.
  4. DTAA tie-breaker year tracking. Any year in which the India-US DTAA Article 4 tie-breaker was claimed, and the IRS notified under IRC §7701(b)(6)(B), is excluded from the 8-of-15 count for IRC §877(e)(2) purposes.
  5. US-situs asset inventory. For NRNC estate-tax purposes, US-situated assets include real estate located in the United States, stock issued by domestic corporations, and certain debt obligations of US persons or governments under IRC §2104; IRC §2105 separately excludes items such as life-insurance proceeds and certain bank deposits. The inventory is the input to any estate-tax reading.
  6. Treaty saving-clause awareness. Article 1, paragraphs 3 and 4 of the India-US DTAA preserve US tax on US citizens and certain US residents notwithstanding the rest of the treaty, with listed exceptions. The saving clause is the reason the DTAA does not switch off US tax on a US person.

None of these checks need a return date to be useful. They are a snapshot of where the US-side clock has been counting while the India-side conversation has been at a different altitude.

The Wind-Down Planner flags the US estate tax review for the US stock you keep after leaving.

7. The annual cross-border file

The companion annual-checklist material is now consolidated here. Keep a year-by-year record rather than reconstructing everything in the return year:

  • US and India travel dates, visa and green-card history, and copies of any treaty-residence disclosures.
  • Foreign-account statements and account authority, including Indian bank, brokerage and retirement accounts. Review each year's FBAR requirements and Form 8938 requirements separately; one form does not replace the other.
  • Lot-level acquisition costs, RSU vesting and sale records, and Indian mutual-fund statements. Ask a US adviser whether PFIC reporting applies instead of assuming the account label settles it.
  • Prior foreign-tax-credit claims, supporting tax statements, PAN access and Indian bank KYC records.
  • A dated currency view of assets, debts and expected Indian spending. A reference rate makes a comparison reproducible; it is not the bank's executable rate or a forecast.

Returning does not itself establish a new tax cost basis. Preserve original acquisition evidence and get a transaction-specific basis review before selling. On the banking side, use the updated NRE/NRO redesignation guide: NRE action on a qualifying return is separate from an existing FCNR(B) deposit's permitted continuation to maturity. The RNOR calculator handles the selected Indian tax year, not US reporting or expatriation tax.

This consolidation adds recordkeeping questions; it is not a new verification of the US thresholds or treaty conclusions earlier in the article.

8. What this article is NOT saying

A few framings the primary sources do not support, and that this piece avoids:

  • NOT stating that surrendering a green card is a recommended or non-recommended step. Whether IRC §877A applies turns on the individual's long-term-resident status under IRC §877(e)(2) and covered-expatriate status under IRC §877A(g)(1) (which incorporates the tests in IRC §877(a)(2)).
  • NOT stating any specific dollar-threshold as the operative figure for any future year. The numbers are indexed annually under IRS Revenue Procedures. As of publication, the §877(a)(2)(A) threshold is USD 211,000 for 2026, the §877A(a)(3) exclusion amount is USD 910,000 for 2026, and the §2010 basic exclusion amount is USD 15,000,000 for decedents dying in 2026.
  • NOT treating the DTAA tie-breaker as a self-executing switch. The notification mechanics in IRC §7701(b)(6)(B), Treas. Reg. §301.7701(b)-7, and the related Form 8833 filing are themselves a compliance event with onward consequences under IRC §877A.

The honest version of the delayed-return conversation includes both clocks. The India-side residency math improves the longer the non-resident streak runs. The US-side ladder accumulates rungs over the same period. Both deserve to be on the table before the return year arrives.

Frequently asked questions

Does the US Substantial Presence Test work like Section 6 of the Income-tax Act?

Both are day-count tests, but the US Substantial Presence Test in IRC §7701(b)(3) uses a weighted three-year formula (current year days + 1/3 prior year days + 1/6 second-prior year days, with a 31-day minimum in the current year). Section 6 of the Income-tax Act, 1961 is a simpler 182-day or 60+365-day test. The two clocks count differently and can disagree in the year of transition.

Does my green card stop mattering for US tax the day I land in India?

No. A lawful permanent resident continues to be a US tax resident under IRC §7701(b)(1)(A)(i) until the green card is formally abandoned (Form I-407) or revoked. The DTAA tie-breaker in Article 4 can allocate residence to India for treaty purposes while US lawful-permanent-resident status, and its tax consequences, continue under domestic US law. Confirm with a US-licensed cross-border tax adviser.

What is the 8-of-15 rule and why does it matter?

IRC §877(e)(2) defines a 'long-term resident' as a noncitizen who has been a lawful permanent resident of the United States in at least 8 taxable years during the 15-taxable-year period ending with the tax year that includes the expatriation date. IRC §877A then applies the mark-to-market exit-tax rules to long-term residents who expatriate and meet a covered-expatriate test in IRC §877A(g)(1) (which incorporates the tests in IRC §877(a)(2)). The 8-year clock is mechanical and runs in the background of every green-card holder's calendar.

Does the India-US DTAA reduce US tax once I am back in India?

The India-US DTAA allocates taxing rights and provides credit-method relief for double taxation in Article 25. For US citizens and lawful permanent residents, the United States retains the right to tax worldwide income under the 'saving clause' in Article 1, paragraph 3, with exceptions listed in Article 1, paragraph 4. The treaty mitigates the overlap; it does not switch off US tax on a US person.
