Interest Tax Rate Between India and Spain Under DTAA

Interest Tax Rate Between India and Spain

Article 12 of the India-Spain Double Taxation Avoidance Agreement (DTAA), signed on 8 February 1993, governs the taxation of interest income flowing between the two countries. The treaty provides a withholding tax rate of 15% compared to India's domestic rate of 20% (plus applicable surcharge and 4% health and education cess) under Section 195 of the Income Tax Act, 1961.

The India-Spain DTAA entered into force on 12 January 1995. Interest taxation provisions are critical for cross-border lending, intercompany financing, External Commercial Borrowings (ECBs), NRO deposits, and corporate debt investments between the two countries. Spain is a significant European trading partner for India, with bilateral trade and investment flows continuing to grow, particularly in infrastructure, renewable energy, and technology sectors. For a comprehensive overview of the full treaty, see our India-Spain DTAA complete guide. For dividend taxation details, refer to our dividend tax rate guide for India-Spain.

Both India and Spain have ratified the OECD Multilateral Instrument (MLI), which introduces the Principal Purpose Test (PPT) as an anti-avoidance measure. While the MFN clause was invoked in March 2024 to reduce royalty and FTS rates to 10%, the interest rate of 15% remains unchanged under the treaty.

Treaty Rate vs Domestic Rate: Detailed Comparison

Article 12 of the India-Spain DTAA establishes a two-tier framework for interest taxation:

15% Rate for General Interest

Under Article 12(2), interest arising in one contracting state and paid to a resident of the other contracting state may be taxed in the source state, but the tax shall not exceed 15% of the gross amount of the interest if the beneficial owner is a resident of the other state. This rate applies uniformly to all categories of interest, including:

• Interest on External Commercial Borrowings (ECBs) from Spanish lenders to Indian borrowers
• Interest on intercompany loans between Spanish and Indian entities
• Interest on NRO fixed deposits held by Spain-resident NRIs
• Interest on corporate bonds and debentures
• Interest on listed and unlisted debt securities
• Interest on syndicated loans where Spanish banks participate
• Interest on trade credits and buyer's credits

Unlike certain other Indian DTAAs (such as India-USA with 10%/15% tiers or India-Switzerland with a flat 10%), the India-Spain treaty does not provide a lower rate for banks or financial institutions. All interest is taxed at a uniform 15%.

0% Rate for Government and Central Bank Interest

Under Article 12(3), interest arising in one contracting state is completely exempt from taxation in that state when:

• The payer is the Government of the source state or a political subdivision or local authority thereof, or
• The beneficial owner is the central bank of the other state (Banco de Espana for Spain, Reserve Bank of India for India)

This exemption covers interest on sovereign debt, government-guaranteed bonds, and central bank deposits. It facilitates government-to-government lending and sovereign investment operations between the two countries.

Who Qualifies for the Reduced Rate

The reduced 15% rate under Article 12 is available only when specific conditions are met:

Beneficial Ownership Requirement

The interest must be beneficially owned by a resident of the other contracting state. The beneficial owner concept requires genuine economic ownership of the interest income. Conduit arrangements, back-to-back lending structures, and nominee arrangements designed to route interest through Spain to obtain treaty benefits do not qualify. The beneficial owner must have the legal right to use and enjoy the interest income without being contractually obligated to pass it to a non-resident of Spain.

Tax Residency Requirement

The interest recipient must be a tax resident of Spain under Article 4 of the treaty. For Spanish entities, this typically requires being subject to Spanish tax by reason of domicile, residence, place of management, or place of incorporation. For individuals, Spanish tax residency is established through habitual abode (more than 183 days in a calendar year) or the centre of vital interests being in Spain.

MLI Principal Purpose Test (PPT)

Since both India and Spain have ratified the MLI, the Principal Purpose Test applies. Treaty benefits on interest may be denied if one of the principal purposes of an arrangement was to obtain the reduced 15% rate. A Spanish entity established primarily to channel interest income from India and claim treaty benefits, without genuine commercial substance or business activity in Spain, would fail the PPT.

GAAR and LOB Considerations

India's domestic General Anti-Avoidance Rule (GAAR) under Sections 95-102 provides an additional anti-abuse mechanism. The India-Spain DTAA also contains a Limitation of Benefits provision introduced through the amending protocol. A Spanish entity claiming treaty benefits must satisfy the LOB conditions, which typically require demonstrating genuine economic activity and that the entity is not primarily used for treaty-shopping purposes.

Interest-Specific Treaty Provisions

Definition of Interest (Article 12(4))

The term "interest" under Article 12(4) means 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, and in particular, income from Government securities and income from bonds or debentures, including premiums and prizes attaching to such securities, bonds, or debentures. Penalty charges for late payment are explicitly excluded from the definition of interest.

Source Rules for Interest (Article 12(6))

Interest is deemed to arise in a contracting state when the payer is a resident of that state. If the person paying interest has a permanent establishment in a contracting state and the debt obligation was incurred in connection with that PE, the interest is deemed to arise in the state where the PE is situated, regardless of the payer's residence. This is particularly relevant for Spanish companies with Indian branches or project offices that take on local debt financing.

Arm's Length Requirement (Article 12(7))

Where the amount of interest paid exceeds the arm's length amount due to a special relationship between the payer and the beneficial owner (or between either of them and a third party), the excess portion is not eligible for the treaty rate. Only the arm's length amount qualifies for the 15% rate. The excess is taxed under domestic law. This provision directly interfaces with India's transfer pricing rules under Sections 92-92F of the Income Tax Act and requires contemporaneous documentation to support the interest rate charged.

PE Attribution Exception (Article 12(5))

If the beneficial owner carries on business through a PE in the source country and the debt-claim generating the interest is effectively connected with that PE, the interest is taxed as business profits under Article 7 rather than under Article 12. Interest income attributable to a Spanish entity's PE in India would be taxed at the applicable corporate tax rate for foreign companies (currently 35% plus surcharge and cess) rather than the 15% withholding rate.

Documentation Required

To claim the reduced 15% DTAA rate on interest, the following documentation is mandatory:

Tax Residency Certificate (TRC)

The Spanish resident must obtain a Tax Residency Certificate from the Agencia Tributaria (Spanish Tax Agency). The TRC confirms tax residency in Spain for the relevant period and is the foundational document for claiming treaty benefits in India.

Form 10F

Form 10F must be furnished to the Indian payer or filed electronically on India's income tax e-filing portal. It requires the recipient's status, nationality, Spanish NIF/CIF (tax identification number), period of residential status, and address in Spain.

Self-Declaration

A self-declaration confirming beneficial ownership, the absence of a permanent establishment in India, the arm's length nature of the interest payment, and that the arrangement is not an impermissible avoidance arrangement is typically required.

RBI/FEMA Documentation (for ECBs)

External Commercial Borrowings from Spanish lenders must comply with FEMA regulations and RBI guidelines. Loan Registration Numbers (LRN), ECB reporting forms, and compliance with all-in-cost ceiling requirements are mandatory alongside DTAA documentation.

Withholding Procedure for Indian Payers

Indian entities paying interest to Spanish residents must comply with Section 195 of the Income Tax Act:

TDS Deduction and Deposit

The Indian payer must deduct TDS at 15% (the DTAA rate) at the time of credit or payment to the Spanish entity, whichever is earlier. The TDS must be deposited with the government by the 7th of the following month. For March deductions, the deadline is 30th April.

Form 15CA and Form 15CB

For interest remittances exceeding INR 5 lakh in a financial year:

• Form 15CB: A Chartered Accountant must file Form 15CB on the Income Tax portal, certifying that TDS has been deducted at the correct rate under Article 12 of the India-Spain DTAA.
• Form 15CA Part C: The remitter then files Form 15CA Part C online, referencing the 15CB acknowledgement number.
• For remittances up to INR 5 lakh: Only Form 15CA Part A is required.

Lower Withholding Certificate (Section 197)

A Spanish entity expecting regular interest income from India can apply to the Assessing Officer for a lower withholding certificate under Section 197. This certificate authorises the Indian payer to deduct TDS at the DTAA rate or at a lower rate determined by the AO based on the recipient's estimated tax liability.

Common Disputes and Judicial Precedents

Transfer Pricing on Intercompany Loans

A significant area of dispute involves the arm's length interest rate on loans between Spanish and Indian affiliated entities. Indian transfer pricing authorities regularly challenge the interest rate charged on intercompany loans, particularly where the rate exceeds comparable market benchmarks. Under Article 12(7), only the arm's length portion of interest qualifies for the treaty rate. Courts have upheld the application of CUP (Comparable Uncontrolled Price) and credit rating-based benchmarking approaches to determine arm's length interest rates.

Guarantee Fee Classification

Disputes arise over whether guarantee fees, commitment fees, and standby charges paid by Indian subsidiaries to Spanish parent companies constitute "interest" under Article 12 or are separately taxable as business income or fees for technical services under Article 13. The classification has significant rate implications (15% for interest vs 10% for FTS post-MFN amendment). Indian courts have generally treated standalone guarantee fees as a separate service rather than interest, unless the fees are embedded in a lending arrangement.

ECB Compliance and Interest Deductibility

External Commercial Borrowings from Spanish entities must comply with RBI's all-in-cost ceiling guidelines under FEMA. If the all-in cost (including interest, commitment fees, and other charges) exceeds the RBI-prescribed ceiling, the borrowing may be non-compliant and interest deductibility may be challenged. Additionally, Indian thin capitalisation rules under Section 94B limit interest deductions on loans from associated enterprises to 30% of EBITDA, which can affect the tax efficiency of Spanish debt financing into India.

Comparison with Other European DTAAs

Spain's 15% interest rate under the DTAA is higher than India's treaties with several other European countries: Switzerland (10%), Germany (10%), the Netherlands (10%), France (10%), and the UK (15%). This rate differential has led some Spanish entities to structure investments through lower-rate jurisdictions, which may be challenged under the MLI's PPT or India's GAAR provisions.

Practical Examples and Calculations

Example 1: Spanish Bank ECB to Indian Company

A major Spanish bank extends a EUR 15 million ECB to an Indian infrastructure company at 4.5% annual interest. Annual interest payment: EUR 675,000.

• Domestic rate: 20% = EUR 135,000 (plus surcharge and cess)
• DTAA rate (Article 12(2)): 15% = EUR 101,250
• Tax saving under DTAA: EUR 33,750 per year

The Spanish bank provides TRC from Agencia Tributaria, Form 10F, and beneficial ownership declaration. The Indian company deducts TDS at 15% and remits EUR 573,750. The ECB must comply with RBI all-in-cost ceiling guidelines.

Example 2: Intercompany Loan from Spanish Parent

A Spanish multinational lends EUR 8 million to its Indian subsidiary at 5% interest. Annual interest payment: EUR 400,000.

• Domestic rate: 20% = EUR 80,000 (plus surcharge and cess)
• DTAA rate (Article 12(2)): 15% = EUR 60,000
• Tax saving under DTAA: EUR 20,000 per year

The interest rate must be at arm's length. If Indian TP authorities determine the arm's length rate is 3.5%, only interest on 3.5% qualifies for the treaty rate; the excess 1.5% may be disallowed under Section 92 and denied treaty benefits under Article 12(7). Additionally, Section 94B thin capitalisation rules may limit the deduction to 30% of the Indian subsidiary's EBITDA.

Example 3: NRI with NRO Fixed Deposit

A Spain-resident NRI has an NRO fixed deposit of INR 30,00,000 with an Indian bank earning 7.5% interest. Annual interest: INR 2,25,000.

• Domestic rate: 20% = INR 45,000
• DTAA rate (Article 12(2)): 15% = INR 33,750
• Tax saving under DTAA: INR 11,250 per year

The NRI furnishes TRC from Agencia Tributaria, Form 10F, and self-declaration to the Indian bank. The bank deducts TDS at 15% instead of 20%. In Spain, the NRI declares the gross interest income and claims Foreign Tax Credit for the 15% Indian tax paid under the credit method.

Frequently Asked Questions

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

The treaty provides a rate of 15% on the gross amount of interest under Article 12(2). Unlike some other Indian DTAAs, there is no differentiation between bank interest and general interest. Interest paid by governments or to central banks is completely exempt under Article 12(3).

Has the MFN clause affected the interest rate?

No. The MFN clause was invoked in March 2024 only for royalties and fees for technical services (reduced from 20% to 10%). The interest rate remains at 15% as no separate MFN notification has been issued for interest under the India-Spain DTAA.

Is the 15% rate higher than other European DTAAs?

Yes. The India-Spain interest rate of 15% is higher than India's treaties with Switzerland (10%), Germany (10%), the Netherlands (10%), and France (10%). The UK treaty also provides 15%. This differential may affect investment structuring decisions.

Does the MLI's Principal Purpose Test apply to interest income?

Yes. Both India and Spain have ratified the MLI. The PPT may deny treaty benefits on interest income if one of the principal purposes of an arrangement was to obtain the 15% rate without genuine commercial substance or business activity in Spain.

Are guarantee fees treated as interest under this treaty?

Generally, no. Indian courts typically hold that standalone guarantee fees are a separate service, not "interest" under Article 12. However, fees embedded in a lending arrangement may be treated as part of the interest cost. The classification matters because FTS is now taxed at 10% (post-MFN) while interest remains at 15%.

Does Section 94B thin capitalisation apply alongside the DTAA?

Yes. Section 94B limits interest deductions on loans from associated enterprises to 30% of EBITDA. This domestic thin capitalisation rule applies regardless of the DTAA rate. The 15% withholding rate applies on the gross interest paid, but the Indian borrower's tax deduction may be limited under Section 94B.

How do I claim the DTAA rate on interest from India?

Provide a valid Tax Residency Certificate from the Agencia Tributaria, file Form 10F on India's e-filing portal, and submit a self-declaration of beneficial ownership to the Indian payer. For remittances exceeding INR 5 lakh, Form 15CA and Form 15CB must also be filed by the remitter.
