Interest Tax Rate Between India and Mexico Under DTAA

Quick answer: Under Article 11(2) of the India-Mexico DTAA, interest is capped at 10% of the gross amount, versus India's domestic rate of 20% under section 207(1) (Table, Sl. No. 3) of the Income-tax Act, 2025 (section 115A of the Income-tax Act, 1961). Article 11(3) goes further: interest derived and beneficially owned by the Government, a political sub-division, local authority or Central Bank of either state, or by named institutions — the Reserve Bank of India, Export-Import Bank of India and National Housing Bank on the Indian side; Banco de Mexico, Banco Nacional de Comercio Exterior, Nacional Financiera and Banobras on the Mexican side — is fully exempt from source-state tax. Interest paid BY a Government, political sub-division, local authority or Central Bank is separately exempt, though that payer-side exemption does not extend to the named development banks. The treaty was signed 10 September 2007 and took effect for Indian withholding tax from 1 April 2011.

Key takeaways:

• General interest is capped at 10% under Article 11(2), versus a 20% domestic rate.
• Article 11(3) fully exempts interest received by government bodies, central banks and a named list of development-finance institutions, and separately interest paid by government bodies and central banks.
• The payer-side exemption is narrower than the recipient-side one — it covers only government/political-subdivision/local-authority/central-bank payers, not the named banks.
• The Protocol expands the definition of "interest" to cover loan commissions, guarantee fees, factoring income, and discount-sale of debt securities.
• Concessional domestic regimes such as section 194LC on certain pre-July-2023 borrowings can occasionally undercut the 10% treaty rate — the treaty is not always the lowest available rate.

Interest Tax Rate Between India and Mexico

The India-Mexico Double Taxation Avoidance Agreement, signed on 10 September 2007 and in force since 1 February 2010, provides one of the more detailed interest-taxation frameworks in India's UN Model-based treaty network. Article 11 caps the general withholding tax rate on interest at 10% of the gross amount, and then carves out a fuller exemption for a specific, named list of government and development-finance recipients — a structure aimed squarely at facilitating sovereign lending and export-credit flows between the two countries.

Interest is one of the most common cross-border payment streams between India and Mexico — corporate loans, bonds, external commercial borrowings, and lending by Mexican development banks such as Banco Nacional de Comercio Exterior (Bancomext) and Nacional Financiera (Nafin) to Indian borrowers. Understanding both the general 10% cap and the narrower exemption is essential for any business or lender structuring cross-border debt in this corridor.

Treaty Rate vs Domestic Rate: Detailed Comparison

Domestic Rate (Without DTAA)

Under section 207(1) (Table, Sl. No. 3) of the Income-tax Act, 2025 (section 115A of the Income-tax Act, 1961), interest paid to a non-resident on foreign-currency borrowings is withheld at 20% (plus applicable surcharge and health & education cess, reaching an effective rate of roughly 20.8% to 21.84%). Rupee-denominated interest paid 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(1) gives the residence state the primary right to tax interest paid to its resident. Article 11(2) then limits the source state's right: "such interest may also be taxed in the Contracting State in which it arises, and according to the laws of that State, but if the beneficial owner of the interest is a resident of the other Contracting State, the tax so charged shall not exceed 10 per cent of the gross amount of the interest." This flat 10% applies to loans, bonds, debentures and other debt-claims generally, before the Article 11(3) exemption is tested.

The Article 11(3) Exemption: Government, Central Banks and Named Institutions

Article 11(3) provides that interest is exempt from source-state tax altogether where it is "derived and beneficially owned by: (a) the Government, a political sub-division or a local authority or Central Bank of the other Contracting State; or (b) (i) in the case of India, the Reserve Bank of India, the Export-Import Bank of India, the National Housing Bank; and (ii) in the case of Mexico, Banco de Mexico, Banco Nacional de Comercio Exterior, S.N.C., Nacional Financiera S.N.C., or Banco Nacional de Obras y Servicios Publicos, S.N.C." (Banobras). Sub-paragraph (c) adds a payer-side limb in a single line, exempting the interest where "the interest is paid by any of the entities mentioned in sub-paragraph (a)" — so that limb reaches only the sovereign payers listed in (a), the Government, a political sub-division, a local authority or the Central Bank, and does not extend to interest merely paid by the named development banks (Bancomext, Nafin, or Banobras, or their Indian counterparts) themselves. Sub-paragraph (d) then leaves the list open-ended, extending the exemption to "any other institution as may be agreed upon from time to time between the competent authorities of the Contracting States through exchange of letters."

Effective Tax Savings

For a Mexican development bank lending USD 10 million to an Indian infrastructure company at 6% annual interest (USD 600,000 per year): if the lender is one of the named institutions (Bancomext, Nafin or Banobras) and the interest is beneficially owned by it, Article 11(3) exempts the interest entirely — a saving of the full 10% treaty rate, or 20% domestic rate, that would otherwise apply. For a private Mexican bank lending on the same terms, the general 10% cap under Article 11(2) still saves USD 60,000 annually compared with the 20% domestic rate.

Who Qualifies for the Reduced Rate

Beneficial Ownership Requirement

Article 11(2) and (3) both require the recipient to be the beneficial owner of the interest — the person with the unrestricted right to use and enjoy the income. A back-to-back lending arrangement, where a Mexican entity borrows from a third-country lender and on-lends to India with no real economic risk or margin, would likely fail this test for both the 10% cap and the Article 11(3) exemption.

Tax Residency

The recipient must be a resident of Mexico under Article 4, which defines residence by domicile, residence, place of management "or any other criterion of a similar nature," and separately provides that the term "also includes that State and any political sub-division or local authority thereof" — a definition directly relevant here, since Article 11(6) deems interest to arise wherever the payer, including a government body, is resident.

No Permanent Establishment Connection

Article 11(5) withdraws both the 10% cap and the exemption where the Mexican beneficial owner carries on business in India through a permanent establishment (or a fixed base for independent personal services) and "the debt claim in respect of which the interest is paid is effectively connected with such permanent establishment or fixed base." The interest is then taxed as business profits under Article 7.

Anti-Abuse: Article 28 Limitation of Benefits Plus MLI PPT

Both countries have ratified the MLI and listed each other as Covered Tax Agreements — India's MLI in force from 1 October 2019, Mexico's from 1 July 2023 — so the MLI's Principal Purpose Test now supplements the treaty's original, pre-BEPS Article 28 Limitation of Benefits article for interest just as it does for the other income categories. The treaty carries no Most Favoured Nation clause, so a lower interest rate India later negotiates elsewhere does not flow through to Mexico.

Interest-Specific Treaty Provisions Under Article 11 and the Protocol

Deemed-Arising Rule (Article 11(6))

"Interest shall be deemed to arise in a Contracting State when the payer is a resident of that State. Where, however, the person paying the interest, whether he is a resident of a Contracting State or not, has in a Contracting State a permanent establishment or a fixed base and such interest is borne by such permanent establishment or fixed base, then such interest shall be deemed to arise in the State in which the permanent establishment or fixed base is situated." Because Article 4(1) defines "resident" to include the State and its political sub-divisions and local authorities, government-sourced interest is squarely caught by this deemed-arising rule.

Protocol Paragraph IV: Expanded Definition of Interest

The Protocol, signed together with the Agreement and integral to it, widens the scope of "interest" beyond ordinary debt-claim income to include: "(a) Commissions related to money lent; (b) Payments made as guarantee of money lent, as well as for the acceptance to act as a guarantor; (c) Payment derived from factoring contracts; (d) Income derived from the alienation of credits; (e) Income derived from financial instruments where there is underlying debt; (f) Income derived from the alienation at discount of securities representing debt." Loan-arrangement fees, guarantee commissions, and factoring income between India and Mexico are therefore taxed as interest under Article 11, not as fees for technical services under Article 12 or as business profits under Article 7.

Arm's Length Rule (Article 11(7))

"Where, owing to a special relationship between the payer and the beneficial owner or between both of them and some other person, the amount of the interest paid exceeds, for whatever reason, the amount which would have been paid in the absence of such relationship, the provisions of this Article shall apply only to the last mentioned amount." Any excess is taxed under each state's domestic law, engaging India's transfer pricing rules for related-party lending.

Documentation Required to Claim the Reduced Rate or Exemption

Tax Residency Certificate (TRC) from SAT

The Mexican lender must obtain a Tax Residency Certificate from Mexico's Servicio de Administración Tributaria (SAT), 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)

Where the TRC lacks prescribed details, Form 41 must be filed electronically, giving the lender's name, status, nationality, RFC (Registro Federal de Contribuyentes) number, and period of residential status — required even for lenders without an Indian PAN.

Self-Declaration and No-PE Certificate

The Mexican lender should provide a self-declaration confirming beneficial ownership of the interest, absence of an Indian PE to which the debt-claim is attributable, and — where claiming the Article 11(3) exemption — confirmation of its status as one of the named institutions.

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 deducts tax at source at the time of credit or payment, whichever is earlier — 10% (or nil for exempt recipients) if documentation is complete, 20% under domestic law if it is not.

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

Before remitting interest to Mexico, the payer must file Form 145 electronically, and obtain a Chartered Accountant's Form 146 for remittances exceeding INR 5 lakh in a financial year.

Section 395(1): Lower or Nil Withholding Certificate

The Mexican lender — not the Indian payer — may apply to the Assessing Officer for a certificate authorising lower or nil withholding under section 395(1) of the Income-tax Act, 2025 (section 197 of the Income-tax Act, 1961). Where the Indian payer itself considers only part of a remittance chargeable to tax, its own route is an application under section 395(2) of the Income-tax Act, 2025 (section 195(2) of the Income-tax Act, 1961).

FEMA and ECB Compliance

Interest paid on external commercial borrowings from Mexican lenders must also comply with the FEMA borrowing framework. Since Notification FEMA 3(R)(5)/2026-RB (in force 16 February 2026), there is no all-in-cost ceiling for ECB with an average maturity of three years or more — pricing is left to prevailing market conditions — while ECB with an average maturity below three years must stay within the Trade Credit ceiling of benchmark rate plus 300 basis points (foreign-currency ECB) or plus 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 — not within seven days of drawdown itself, and never through the FIRMS portal.

Common Disputes and Practical Considerations

Loan Fees Characterised as Interest, Not FTS

Because Protocol paragraph IV brings commissions on money lent, guarantee payments and factoring income within the definition of "interest," a fee that is in substance consideration for a debt-claim takes Article 11 treatment — the 10% cap, or the Article 11(3) exemption where the lender is a named institution — rather than the 10% FTS rate under Article 12. Correct characterisation matters most for export-credit and development-finance facilities, where the underlying loan interest may be exempt but an associated fee, if mischaracterised as a service fee, would otherwise attract 10% under Article 12(2).

Surcharge and Cess Over the Treaty Rate

As with the other income articles, whether surcharge and cess can be levied over and above the 10% treaty cap on interest remains a recurring point of dispute; several ITAT benches have held that the treaty rate is inclusive of both.

Concessional Domestic Rates Can Beat the Treaty

The treaty rate is not always the lowest available. Section 194LC provides a concessional domestic withholding rate on certain external commercial borrowings raised before July 2023, which can in specific cases be lower than the 10% treaty rate — taxpayers should compare both routes under section 159(4) of the Income-tax Act, 2025 (section 90(2) of the Income-tax Act, 1961) rather than assuming the treaty is automatically the better option.

Practical Examples and Calculations

Example 1: Private Mexican Bank Loan to an Indian Company

A private Mexican commercial bank — not one of the Article 11(3) named institutions — lends USD 15 million to an Indian manufacturer at 7% annual interest (USD 1,050,000). Without the DTAA, Indian TDS at 20% is USD 210,000. With the DTAA, TDS at 10% is USD 105,000 — a saving of USD 105,000 annually, for which the bank claims a foreign tax credit in Mexico.

Example 2: Nacional Financiera (Nafin) Development Loan

Nacional Financiera S.N.C., a Mexican state development bank named in Article 11(3)(b)(ii), lends to an Indian renewable-energy company at 5% interest on USD 20 million (USD 1,000,000 annually). Because Nafin is a named institution and the beneficial owner, the interest is fully exempt from Indian withholding under Article 11(3) — the Indian company pays interest gross, with no TDS leakage, provided Nafin's TRC and self-declaration confirm its status.

Frequently Asked Questions

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

Article 11(2) caps general interest withholding at 10% of the gross amount, versus India's domestic rate of 20% under section 207(1) of the Income-tax Act, 2025 (section 115A of the Income-tax Act, 1961). Certain government and institutional interest is fully exempt under Article 11(3).

Which institutions qualify for the full interest exemption?

Article 11(3) exempts interest beneficially owned by the Government, a political sub-division, local authority or Central Bank of either state, plus the Reserve Bank of India, Export-Import Bank of India and National Housing Bank on the Indian side, and Banco de Mexico, Banco Nacional de Comercio Exterior, Nacional Financiera, and Banobras on the Mexican side.

Does the payer-side exemption cover interest paid by the named development banks?

No. The payer-side exemption in Article 11(3) covers only interest paid by a Government, political sub-division, local authority or Central Bank — not interest merely paid by Bancomext, Nafin, Banobras, or their Indian counterparts. Only the recipient-side test applies to those named banks.

Are loan fees and guarantee commissions taxed as interest or as fees for technical services?

As interest. Protocol paragraph IV expands the definition of interest to include commissions on money lent, guarantee payments, factoring income, and discount-sale of debt securities, so these are taxed under Article 11 rather than as fees for technical services under Article 12.

Is the 10% treaty rate always better than the domestic rate?

Usually, but not always. India's domestic section 194LC provides a concessional rate for certain external commercial borrowings raised before July 2023 that can in specific cases undercut the treaty's 10% cap — taxpayers should apply whichever rate is genuinely more beneficial under section 159(4) of the Income-tax Act, 2025 (section 90(2) of the Income-tax Act, 1961).

What documentation does a Mexican lender need to claim the reduced rate or exemption?

A Tax Residency Certificate from SAT, Form 41 (formerly Form 10F) filed electronically, and a self-declaration of beneficial ownership and non-PE status — plus, for the Article 11(3) exemption, confirmation of the lender's status as a named institution. The Indian payer must file Form 145, and Form 146 for remittances exceeding INR 5 lakh.
