Interest Tax Rate Between India and Luxembourg Under DTAA

Quick answer: Under Article 11(2) of the India-Luxembourg DTAA, interest paid by an Indian borrower to a Luxembourg beneficial owner is capped at 10% of the gross amount, against India's domestic withholding rate of 20% on foreign-currency borrowings under section 207(1) (Table, Sl. No. 3) of the Income-tax Act, 2025 (section 115A of the Income-tax Act, 1961). There is no separate concessional tier for bank or financial-institution lending -- the 10% rate is uniform. A narrow, recipient-side exemption under Article 11(3) makes interest fully exempt where it is derived and beneficially owned by the Government, a political sub-division or local authority of either State, by the Reserve Bank of India, the Export-Import Bank of India or the National Housing Bank, or by Luxembourg's National Credit and Investment Corporation (SNCI) or its Central Bank -- but not merely because a loan is government-guaranteed.

Key takeaways:

• Interest is capped at 10% under Article 11(2), a single flat rate covering all lenders, including banks.
• Article 11(3) exempts interest only where the Government, RBI, Exim Bank, NHB, SNCI or the Central Bank of Luxembourg is the actual recipient -- the exemption is recipient-side, not payer-side.
• The treaty sets no separate protocol condition narrowing the 10% cap, unlike some Indian DTAAs.
• Interest of every kind falls within the definition, including bond and debenture premiums; only late-payment penalty charges are excluded.
• The MLI's Principal Purpose Test applies to this treaty from FY 2020-21, alongside India's domestic GAAR.

Interest Tax Rate Between India and Luxembourg

The India-Luxembourg Double Taxation Avoidance Agreement (DTAA), signed 2 June 2008, in force from 9 July 2009 and effective in India from 1 April 2010, sets out the taxation of interest income under Article 11. Luxembourg is a significant centre for structured finance, bond issuance and cross-border lending into India, so the treaty's interest article is directly relevant to loans, debentures, and government securities flowing between the two countries. Article 11(2) caps India's withholding tax on interest paid to a Luxembourg beneficial owner at 10% of the gross amount, roughly half the 20% domestic rate under section 207(1) of the Income-tax Act, 2025.

Treaty Rate vs Domestic Rate: Detailed Comparison

Domestic Rate (Without DTAA)

Under section 207(1) of the Income-tax Act, 2025 (section 115A of the Income-tax Act, 1961), interest paid to a non-resident on money borrowed in foreign currency is subject to withholding tax at 20%, plus applicable surcharge and health & education cess. Rupee-denominated interest owed to non-residents falls outside this entry and is instead withheld at the rates in force -- 30% for non-corporate recipients, 35% for foreign companies.

DTAA Rate (With Treaty)

Article 11(2) restricts India's taxing right on interest paid to a Luxembourg beneficial owner to a maximum of 10% of the gross amount. This is a single flat rate: the treaty draws no distinction between a loan from a Luxembourg bank, a bond, a debenture, or an ordinary commercial loan -- all fall under the same 10% ceiling once the beneficial-ownership and residency tests are met.

The Article 11(3) Exemption -- Recipient-Side Only

The treaty text reads: "interest arising in a Contracting State shall be exempt from tax in that State, provided that it is derived and beneficially owned by" -- (a) the Government, a political sub-division or a local authority of the other Contracting State; (b)(i), on the India side, the Reserve Bank of India, the Export-Import Bank of India or the National Housing Bank; (b)(ii), on the Luxembourg side, the National Credit and Investment Corporation (SNCI) or the Central Bank of Luxembourg; or (c) any other institution the two competent authorities agree upon by exchange of letters. This is a recipient-side exemption: it turns on who actually derives and beneficially owns the interest, not on who guarantees the underlying loan. A commercial loan merely guaranteed by the Luxembourg or Indian government -- as opposed to one where the government itself is the lender -- does not qualify. The treaty's 2008 Protocol adds no further condition to this exemption or to the 10% cap.

Effective Tax Savings

For a Luxembourg lender advancing EUR 10 million to an Indian borrower at 5% annual interest (EUR 500,000), the treaty saves EUR 50,000 a year in withholding tax compared with the 20% domestic rate -- and, where the lender is the SNCI or the Central Bank of Luxembourg, the entire EUR 50,000 domestic tax is eliminated under Article 11(3).

Who Qualifies for the Reduced Rate

Beneficial Ownership Requirement

Article 11(2) applies only where the Luxembourg recipient is the beneficial owner of the interest -- the party with the unrestricted right to use and enjoy it, not a conduit passing it on to a third-country lender. A back-to-back lending structure with no genuine economic risk at the Luxembourg level is vulnerable to having the reduced rate denied.

Tax Residency

The recipient must be a Luxembourg tax resident under Article 4 of the DTAA and must hold a Tax Residency Certificate (TRC) from Luxembourg's Administration des Contributions Directes (ACD) for the relevant period.

Anti-Abuse: MLI Principal Purpose Test and GAAR

The India-Luxembourg DTAA is a Covered Tax Agreement under the MLI, and the Principal Purpose Test applies to Indian withholding tax from FY 2020-21. Structured lending routed through Luxembourg primarily to access the 10% rate -- or the Article 11(3) exemption -- can be challenged under the PPT, and independently under India's domestic General Anti-Avoidance Rules where the arrangement lacks commercial substance. The treaty also carries its own Limitation of Benefits provision. Article 29 preserves each State's domestic anti-evasion rules, denies the benefits of the Agreement to an enterprise whose creation had obtaining those benefits as its main purpose or one of its main purposes, and expressly covers legal entities without bona fide business activities. Article 30 goes further: the Agreement does not apply at all to holding companies governed by the special Luxembourg laws it names, or to other companies enjoying a similar special fiscal treatment under Luxembourg law, nor to income an Indian resident derives from such companies. A Luxembourg vehicle established under a special fiscal regime should therefore confirm its treaty eligibility before relying on the reduced rate.

No PE Attribution

Under Article 11(5), the reduced rate and the exemption both fall away if the debt-claim is effectively connected with a permanent establishment or fixed base the Luxembourg lender has in India. The interest is then taxed as business profits under Article 7 (or Article 14 for independent personal services).

Interest-Specific Treaty Provisions Under Article 11

Definition of Interest (Article 11(4))

The treaty defines "interest" as income from debt-claims of every kind, whether or not secured by mortgage and whether or not carrying a right to participate in the debtor's profits, including income from government securities and from bonds or debentures, together with premiums and prizes attaching to such securities, bonds or debentures. Penalty charges for late payment are expressly excluded from this definition. Because the definition covers debt-claims "of every kind" plus premiums, a redemption premium on a Luxembourg-issued bond or debenture falls within Article 11 rather than being treated as a separate category of income.

Article 11(1): Residence-State Taxation

Interest arising in one Contracting State and paid to a resident of the other may be taxed in that other (residence) State.

Article 11(2): Source-State Taxation (10% Cap)

The source State may also tax the interest, but where the beneficial owner is resident in the other State, "the tax so charged shall not exceed 10 per cent of the gross amount of the interest."

Article 11(3): The Recipient-Side Exemption

As set out above, interest is fully exempt in the source State where derived and beneficially owned by specified government bodies and institutions -- with no equivalent payer-side carve-out (contrast some other Indian treaties, which also exempt interest merely because the source-State government itself is the payer).

Article 11(6): Source Rule

Interest is deemed to arise in a Contracting State when the payer is a resident of that State; where the payer has a PE or fixed base elsewhere with which the debt was incurred, and the interest is borne by that PE or fixed base, the interest is instead deemed to arise where the PE or fixed base is situated.

Article 11(7): Arm's Length Rule

Where a special relationship between payer and beneficial owner inflates the interest above an arm's-length amount, only the arm's-length portion enjoys the treaty rate; the excess remains taxable under each State's domestic law, closely tied to India's transfer pricing rules.

Documentation Required to Claim the Reduced Rate

Tax Residency Certificate (TRC)

The Luxembourg lender must provide a TRC from the Administration des Contributions Directes (ACD), mandatory under section 159(8) of the Income-tax Act, 2025 (section 90(4) of the Income-tax Act, 1961).

Form 41 (formerly Form 10F)

If the TRC omits any prescribed detail, Form 41 must be filed electronically on the Indian e-filing portal -- PAN is not mandatory for this filing.

Self-Declaration

A self-declaration of beneficial ownership and no-PE status supports the Indian payer's compliance file, along with the loan agreement and interest computation.

Withholding Procedure for Indian Payers

Section 393(2): TDS Obligation

Under section 393(2) of the Income-tax Act, 2025 (Table, Sl. No. 17; section 195 of the Income-tax Act, 1961), the Indian payer must deduct TDS at the time of credit or payment, whichever is earlier -- 10% with valid treaty documentation, 20% (on foreign-currency debt) without it.

Forms 145 and 146 (formerly Forms 15CA and 15CB)

Before remitting interest to Luxembourg, the payer must file Form 145 electronically; for remittances exceeding INR 5 lakh in a financial year, a Chartered Accountant must also issue Form 146 certifying the applicable treaty rate.

Section 395(1): Lower Withholding Certificate

A Luxembourg lender expecting a lower actual liability can apply to the Assessing Officer for a lower or nil withholding certificate under section 395(1) of the Income-tax Act, 2025 (section 197 of the Income-tax Act, 1961).

FEMA and ECB Compliance

Where the interest arises on an External Commercial Borrowing, pricing must also satisfy the Foreign Exchange Management (Borrowing and Lending) Regulations, 2018, whose Schedule I was substituted by Notification FEMA 3(R)(5)/2026-RB, in force 16 February 2026. Under that framework there is no all-in-cost ceiling for ECB with an average maturity of three years or more -- pricing is in line with prevailing market conditions -- while ECB with an average maturity below three years must stay within the Trade Credit ceiling of benchmark rate + 300 basis points (foreign-currency ECB) or + 250 basis points (rupee ECB). Form ECB-2 must be filed through the designated AD Category-I bank within seven calendar days from the end of the month in which proceeds were received or debt servicing was undertaken. See FEMA and RBI compliance services for structuring assistance.

Practical Examples and Calculations

Example 1: Luxembourg Fund Lending to an Indian Corporate

Lux Credit S.a r.l., a Luxembourg-resident financing company fully subject to Luxembourg corporation tax, lends EUR 15 million to an Indian infrastructure company at 6% per annum (EUR 900,000 annual interest).

• Without DTAA: TDS at 20% = EUR 180,000. Net interest received = EUR 720,000.
• With DTAA: TDS at 10% = EUR 90,000. Net interest received = EUR 810,000.
• Annual saving: EUR 90,000.

Example 2: Loan from the Central Bank of Luxembourg

Where a loan to an Indian borrower is made directly by the Central Bank of Luxembourg (or by the SNCI) and that institution is the actual beneficial owner of the interest, Article 11(3)(b)(ii) makes the interest fully exempt from Indian withholding tax -- an effective rate of 0%. If the same loan were merely guaranteed, rather than made, by the Luxembourg state or the Central Bank, the exemption would not apply and the 10% cap under Article 11(2) would govern instead.

Example 3: Bond Redemption Premium

A Luxembourg investor holds Indian corporate bonds redeemed at a premium to face value. Because Article 11(4) defines interest to include "premiums and prizes attaching to such securities, bonds or debentures," the redemption premium is taxed as interest at the 10% treaty rate, not at a different (and potentially higher) domestic rate applicable to other forms of income.

Frequently Asked Questions

What is the interest tax rate under the India-Luxembourg DTAA?

Article 11(2) caps India's withholding tax on interest paid to a Luxembourg beneficial owner at 10% of the gross amount, against a domestic rate of 20% on foreign-currency borrowings. There is no separate lower tier for bank loans -- 10% is the uniform treaty rate.

Which interest payments are fully exempt under the treaty?

Article 11(3) exempts interest derived and beneficially owned by the Government, a political sub-division or local authority of either State, by the Reserve Bank of India, the Export-Import Bank of India or the National Housing Bank, or by Luxembourg's National Credit and Investment Corporation (SNCI) or its Central Bank. Other institutions qualify only if the two competent authorities agree by exchange of letters.

Is a government-guaranteed loan exempt from withholding tax?

No. The Article 11(3) exemption is recipient-side: it applies only where the exempt body is the actual beneficial owner of the interest, not merely a guarantor of the underlying loan. A commercial loan guaranteed by a government body still attracts the 10% treaty rate.

Does the 10% rate cover bond and debenture premiums?

Yes. Article 11(4) defines interest broadly to include income from debt-claims of every kind, government securities, bonds and debentures, and any premiums or prizes attaching to them. Only penalty charges for late payment are excluded from the definition.

What documentation does a Luxembourg lender need?

A Tax Residency Certificate from the Administration des Contributions Directes, Form 41 (electronically filed) if the TRC lacks required details, a self-declaration of beneficial ownership and no-PE status, and the underlying loan agreement. The Indian payer must also file Form 145 (and Form 146 above INR 5 lakh).

Does the Principal Purpose Test apply to interest claims under this treaty?

Yes. The India-Luxembourg DTAA is a Covered Tax Agreement under the MLI, and the Principal Purpose Test applies to Indian withholding tax from FY 2020-21. Interest routed through Luxembourg primarily to access the 10% rate or the Article 11(3) exemption can be denied treaty benefit under the PPT, and independently under India's domestic GAAR.
