Citizenship Act Section 9: Why Acquiring Foreign Passport Ends Indian Citizenship Automatically

For an Indian who takes the oath of allegiance to the United States, the United Kingdom, Canada or any other state, the loss of Indian citizenship is not a paperwork formality that can be deferred. Under Section 9 of the Citizenship Act 1955, the moment a citizen of India voluntarily acquires the citizenship of another country, Indian citizenship ceases by operation of law, automatically and from the date of acquisition, with no order, hearing or discretion involved. The Act was passed on 30 December 1955 and India has never amended it to permit dual nationality, which is why the Overseas Citizen of India (OCI) card, introduced in 2005, confers a lifelong visa but not a second passport.

This distinction matters because the foreign passport that ends your political citizenship simultaneously rewrites your status under three separate Indian legal codes: the Foreign Exchange Management Act 1999 (FEMA), the Income-tax Act 1961, and the Reserve Bank of India's account-classification rules. A naturalised foreign citizen who continues operating a resident savings account, holding agricultural land, or filing returns as an ordinary resident is in technical breach within days of the naturalisation ceremony. This guide maps the transaction precisely: what Section 9 triggers, how India taxes the new foreign national, how the host country's foreign tax credit interacts, and how money moves home afterwards.

FEMA / DTAA Position

Section 9 of the Citizenship Act 1955 operates on a single test: voluntary acquisition. A child who acquires foreign citizenship by birth abroad is not caught, but an adult who applies for and is granted naturalisation triggers automatic cessation on the date the foreign certificate is issued. The alternative route, Section 8, is voluntary renunciation by declaration for an adult who wishes to give up Indian citizenship without first holding a foreign passport; both routes converge on the same obligation under the Passports Act 1967, namely surrender of the Indian passport at the nearest Indian mission and collection of a Renunciation Certificate. The Ministry of Home Affairs has, since 2020, levied a penalty for retaining an Indian passport beyond three years of acquiring foreign citizenship, so the surrender is time-bound.

The day citizenship ceases, residential status under FEMA must be reassessed. FEMA defines residence by intent and physical presence rather than by passport, but a person who has emigrated and naturalised abroad is, in the ordinary case, a "person resident outside India" under Section 2(w) of FEMA 1999. That single reclassification is the hinge for everything that follows. Under Section 6 of FEMA, capital account transactions by a non-resident require Reserve Bank permission unless specifically permitted, whereas resident individuals enjoy the Liberalised Remittance Scheme allowance of USD 250,000 per financial year that a new foreign citizen can no longer use.

The table below contrasts the two exit routes that both end in the same FEMA reclassification.

On the treaty side, a naturalised citizen becomes a "resident" of the new country for Double Taxation Avoidance Agreement (DTAA) purposes once domestic residence tests are met. For the India-United States treaty, in force from 12 September 1991, the DTAA does not switch off India's right to tax India-source income. It is a common and costly error to read a treaty as waiving India's tax on such gains; under the India-USA DTAA, India retains the right to tax long-term capital gains at 12.5%, taxes portfolio dividends at 25% and interest at 15%, with the resident country granting relief through a credit under Article 24.

Tax Treatment in India

The first trap is conflating citizenship with tax residence. Losing Indian citizenship under Section 9 does not by itself make you a non-resident for income tax. Residential status is decided every year under Section 6 of the Income-tax Act 1961 on days of physical presence; a foreign citizen physically in India for 182 days or more in a financial year is taxed as a resident on global income, while one below that threshold is taxed only on India-source income. So the foreign passport changes your FEMA status immediately but your tax status only at the next presence test.

Once you are assessed as a Non-Resident Indian for a given year, India taxes only India-source receipts, and tax is collected largely through withholding under Section 195 of the Income-tax Act 1961 rather than advance tax. Rental income from Indian property, capital gains on Indian shares and mutual funds, and interest on non-exempt deposits all attract TDS at the point of payment. You can model the resulting liability with the NRI income tax calculator and the rental income tax calculator, both of which apply the post-Budget-2024 rates.

The capital gains regime changed sharply on 23 July 2024 and applies to foreign citizens identically. Long-term gains on listed equity and equity mutual funds are taxed at 12.5% beyond an annual exemption of Rs 1.25 lakh, while short-term equity gains are taxed at 20%. Gains on property and gold acquired on or after 23 July 2024 are taxed at 12.5% without indexation; assets acquired before that date may use the grandfathered route of 20% with indexation. The table below sets out the headline numbers a departing citizen must plan around.

Surcharge is layered on base tax above income thresholds: 10% between Rs 50 lakh and Rs 1 crore, 15% between Rs 1 crore and Rs 2 crore, and 25% above Rs 2 crore, with a health and education cess of 4% on top. A frequent misconception is that a 37% top rate still applies to large incomes; that 37% figure survives only in the old regime, while under current new-regime rules the surcharge is capped at 25%, and capital gains income never attracts more than the 15% surcharge band in any case. The new-regime rebate under Section 87A is now Rs 60,000 for resident total income up to Rs 12 lakh, but a non-resident cannot claim the Section 87A rebate at all, which is a detail many newly naturalised filers miss.

Tax Treatment Abroad

The country whose passport ended your Indian citizenship now taxes you as one of its residents, and the mechanism that prevents the same rupee being taxed twice is the foreign tax credit. Under Article 24 of the India-USA DTAA, the United States, as the country of residence, allows a credit for Indian tax paid on India-source income, subject to its own limitation rules. The practical Indian-side document is Form 67, which must be filed before the income-tax return to substantiate the foreign tax credit claim, a workflow set out in our explainer on the India-USA DTAA and Form 67.

The credit is not automatic and not unlimited. The resident country grants relief only up to its own tax on that slice of income, so where the Indian rate exceeds the foreign rate, the excess Indian tax is not refunded by either treasury. For example, India's 25% withholding on portfolio dividends under Article 10 of the India-USA DTAA can be higher than the rate a US resident pays domestically on qualified dividends, leaving a timing or absolute mismatch that planning must address. This is why the treaty rate, not the higher domestic Indian rate, should be claimed at source through a valid Tax Residency Certificate from the foreign tax authority.

Crucially, the treaty never converts an Indian taxing right into a waiver of tax on capital gains. Even with a US passport and US residence, a long-term gain on Indian listed equity remains taxable in India at 12.5%, and the US credit mechanism, not an Indian exemption, is what prevents double taxation. Foreign citizens who assume their Indian shares are tax-free abroad routinely under-report, because the India-USA DTAA in force since 12 September 1991 allocates, rather than waives, the gain.

Repatriation Mechanics

The practical consequence of Section 9 that hits fastest is banking. A resident savings account cannot be operated by a person resident outside India; under FEMA, it must be redesignated as a Non-Resident Ordinary (NRO) account or closed without delay once you become a foreign citizen. Income arising in India, such as rent, dividends and pension, flows into the NRO account, while fresh foreign earnings are routed to a Non-Resident External (NRE) or Foreign Currency Non-Resident (FCNR) account.

The repatriability of these accounts differs sharply, and the difference decides how money reaches you abroad. NRE and FCNR balances, both principal and interest, are freely repatriable. NRO balances are repatriable only up to USD 1 million per financial year, net of applicable taxes, and each remittance requires a chartered accountant's certificate in Form 15CB and an online declaration in Form 15CA. You can size a transfer against the cap and tax drag using the NRI repatriation calculator before instructing your bank.

Interest on NRE and FCNR deposits is exempt from Indian tax under Section 10(4)(ii) of the Income-tax Act 1961 for a person resident outside India under FEMA, which is one reason a newly naturalised citizen should redesignate promptly rather than leaving funds in a resident account that earns fully taxable interest. The USD 1 million NRO window is a per-financial-year ceiling set by the Reserve Bank, so large legacy estates, such as sale proceeds of inherited property, may need to be repatriated across several years, each tranche cleared through the TDS and Form 15CA/15CB pipeline.

One asset class needs a separate flag: agricultural land, plantation property and farmhouses cannot be acquired by a non-resident or foreign citizen, though such property already owned before the change of status may be retained and its sale proceeds repatriated within the USD 1 million limit. The Reserve Bank's master directions under FEMA 1999 govern these holdings, and the rules apply from the date of cessation of Indian citizenship rather than from any later filing.

FAQ

Do I lose Indian citizenship the day I take a foreign oath, or when I surrender my passport?

You lose it on the date you voluntarily acquire the foreign citizenship, under Section 9 of the Citizenship Act 1955, not on the later date you surrender the Indian passport. Cessation is automatic and by operation of law; surrendering the passport and obtaining the Renunciation Certificate is a compliance step that must follow, with a Ministry of Home Affairs penalty for retaining the Indian passport beyond three years.

Does an OCI card give me dual citizenship?

No. The OCI card, introduced in 2005, gives lifelong multiple-entry visa rights and the ability to live, work and study in India, but an OCI holder remains a foreign citizen. India has not permitted dual nationality since the Citizenship Act came into force on 30 December 1955, so OCI is a long-term residency and travel facility, not a second nationality.

Will I become a non-resident for income tax the moment I get a foreign passport?

Not automatically. Tax residence is tested separately each year under Section 6 of the Income-tax Act 1961 on days of physical presence; 182 days or more in India in a financial year can still make a foreign citizen a tax resident taxed on global income. The foreign passport changes your FEMA status at once, but your income-tax status only at the next annual presence test.

Are my Indian capital gains exempt because of the DTAA with my new country?

No. Under the India-USA DTAA in force since 12 September 1991, India retains the right to tax India-source capital gains, with long-term listed-equity gains taxed at 12.5% above the Rs 1.25 lakh exemption. The treaty prevents double taxation through a foreign tax credit under Article 24, claimed via Form 67, not through an Indian exemption.

How much money can I send abroad from my NRO account each year?

Up to USD 1 million per financial year, net of applicable Indian taxes, under the Reserve Bank's repatriation rules. Each remittance needs a Form 15CB certificate from a chartered accountant and an online Form 15CA declaration, and balances in NRE or FCNR accounts are separately and fully repatriable.

What happens to my resident savings account after I naturalise abroad?

It must be redesignated as an NRO account or closed once you become a person resident outside India under FEMA 1999, because a non-resident cannot operate a resident account. India-source income then flows into the NRO account, while foreign earnings go to NRE or FCNR accounts whose interest is exempt under Section 10(4)(ii) of the Income-tax Act 1961.

Can I keep agricultural land I owned before changing citizenship?

Property such as agricultural land, plantations and farmhouses cannot be freshly acquired by a foreign citizen under FEMA 1999, but land already owned before cessation of Indian citizenship may generally be retained. On sale, proceeds may be repatriated within the USD 1 million per financial year limit, subject to TDS and the Form 15CA/15CB process.
