Interest Tax Rate Between India and Switzerland Under DTAA

Interest Tax Rate Between India and Switzerland

Article 11 of the India-Switzerland Double Taxation Avoidance Agreement (DTAA), signed on 2 November 1994, governs the taxation of interest income flowing between the two countries. The treaty provides a reduced withholding tax rate of 10% 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.

Cross-border interest taxation between India and Switzerland is particularly significant given Switzerland's role as a global financial centre. Swiss banks manage over USD 4 trillion in private assets, and Swiss entities are major lenders in international debt markets. The treaty's interest provisions affect External Commercial Borrowings (ECBs), intercompany loans, NRO/NRE deposits, corporate bond investments, and government-backed lending facilities between the two countries. For a comprehensive overview of the full treaty, see our India-Switzerland DTAA complete guide. For dividend taxation details, refer to our dividend tax rate guide for India-Switzerland.

Unlike some other Indian DTAAs that differentiate between bank interest and general interest (such as the India-USA treaty with 10%/15% tiers), the India-Switzerland DTAA applies a uniform 10% rate on all interest payments, with complete exemptions for loans made or guaranteed by government-designated institutions like the Export-Import Bank of India.

Treaty Rate vs Domestic Rate: Detailed Comparison

Article 11 of the India-Switzerland DTAA establishes a clear framework for interest taxation with two tiers:

10% Rate for General Interest

Under Article 11(2), interest arising in one contracting state and paid to a resident of the other contracting state may be taxed in the state where the interest arises, but the tax shall not exceed 10% of the gross amount of the interest if the beneficial owner is a resident of the other state. This rate applies uniformly to:

• Interest on corporate loans and syndicated lending
• Interest on ECBs from Swiss lenders to Indian borrowers
• Interest on NRO fixed deposits held by Swiss-resident NRIs
• Interest on corporate bonds and debentures
• Interest on intercompany loans between Swiss and Indian entities
• Interest on private lending arrangements and listed debt securities

0% Rate for Government-Backed Loans (EXIM Bank)

Under Article 11(3), interest arising in one contracting state is completely exempt from taxation in that state if it is paid in respect of a loan made, guaranteed, or insured by the Export-Import Bank of India or equivalent Swiss governmental institutions as specified and agreed in letters exchanged between the competent authorities. This exemption extends to development finance institutions and export credit agencies operating under government mandates.

Swiss Matching Credit Provision

A unique feature of the India-Switzerland DTAA is the matching credit provision in the Protocol. Where a Swiss resident derives interest covered under Sections 10(4), 10(4B), 10(15)(iv), or 80L of the Indian Income Tax Act (interest that may be exempt or taxed at reduced rates in India), Switzerland grants a relief (matching credit) equal to 10% of the gross interest amount. This ensures that Swiss residents receiving tax-exempt Indian interest income still receive credit in Switzerland as if Indian tax had been paid at the treaty rate.

Who Qualifies for the Reduced Rate

The reduced rates under Article 11 are 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 that the recipient has the legal and economic right to use, enjoy, and dispose of the interest income independently. Conduit arrangements, back-to-back loan structures, and nominee arrangements do not qualify for treaty benefits. Swiss financial intermediaries acting as agents or fiduciaries for third-party accounts would not be considered beneficial owners unless they bear the economic risk of the lending activity.

Tax Residency Confirmation

The interest recipient must qualify as a tax resident of Switzerland under Article 4 of the treaty. For Swiss entities, this requires being subject to Swiss tax by reason of domicile, residence, place of management, or place of incorporation. For individuals, Swiss tax residency is established through habitual abode, domicile, or registration with cantonal authorities.

No Specific LOB Clause

The India-Switzerland DTAA does not contain a standalone Limitation of Benefits (LOB) article. However, India's domestic GAAR provisions (Sections 95-102 of the Income Tax Act) and the MLI's Principal Purpose Test (PPT) serve as anti-avoidance mechanisms. A Swiss entity that is established primarily to route interest income and obtain treaty benefits without genuine commercial substance may be denied the 10% rate.

Interest-Specific Treaty Provisions

Source Rules for Interest (Article 11(6))

Interest is deemed to arise in a contracting state when the payer is a resident of that state. Additionally, 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 provision is particularly relevant for Swiss companies with Indian PEs that take on local debt financing.

Arm's Length Requirement (Article 11(5))

Where the amount of interest 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 10% rate. The excess is taxed under domestic law, subject to the other provisions of the treaty. This anti-avoidance provision directly intersects with India's transfer pricing rules under Sections 92-92F of the Income Tax Act.

PE Attribution Exception (Article 11(4))

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 11. This means interest income attributable to a Swiss entity's PE in India is taxed at the applicable corporate tax rate (typically 35% for foreign companies) rather than the 10% withholding rate.

Documentation Required

To claim the reduced 10% DTAA rate on interest, the following documentation is mandatory:

Tax Residency Certificate (TRC)

The Swiss resident must obtain a Tax Residency Certificate from the Swiss cantonal tax authority or the Swiss Federal Tax Administration. The TRC confirms tax residency in Switzerland 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, providing the recipient's status, nationality, Swiss tax identification number (Steuernummer/AHV number), period of residential status, and address. Form 10F can be filed electronically on India's income tax e-filing portal.

Self-Declaration

A self-declaration confirming beneficial ownership, the absence of a permanent establishment in India, and the arm's length nature of the interest payment is typically required. The declaration should confirm that the lending arrangement has genuine commercial substance.

RBI/FEMA Documentation (for ECBs)

External Commercial Borrowings from Swiss lenders to Indian borrowers must comply with FEMA regulations and RBI guidelines. Loan Registration Numbers (LRN), ECB reporting forms, and compliance with all-in-cost ceilings are additional requirements beyond the DTAA documentation.

Withholding Procedure for Indian Payers

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

TDS Deduction and Deposit

The Indian payer must deduct TDS at 10% (the DTAA rate) at the time of credit or payment to the Swiss 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 11 of the India-Switzerland 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 Swiss resident 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 a lower rate if the AO determines the actual tax liability will be lower based on available deductions and exemptions).

Common Disputes and Judicial Precedents

Transfer Pricing on Intercompany Loans

A major area of dispute involves the arm's length interest rate on loans between Swiss and Indian entities. Indian transfer pricing authorities often challenge the interest rate charged on intercompany loans, particularly where Swiss parent companies lend to Indian subsidiaries at rates above comparable market benchmarks. Under Article 11(5), the excess interest above the arm's length amount is denied treaty benefits. Courts have generally upheld the application of transfer pricing provisions to determine the arm's length rate, using comparable uncontrolled price (CUP) or credit rating-based benchmarking methodologies.

Guarantee Fees and Commitment Charges

Disputes frequently arise over whether guarantee fees, commitment fees, standby charges, and similar payments constitute "interest" under Article 11 or are separately taxable as business income or fees for included services. Indian courts have generally held that guarantee fees paid by an Indian subsidiary to its Swiss parent for guaranteeing a third-party loan constitute a separate service and are not "interest" under the treaty. However, if such fees are embedded in the overall lending arrangement, they may be treated as part of the interest cost.

MFN Clause Impact on Interest

Unlike dividends (where the MFN clause had reduced the rate from 10% to 5%), the interest rate under the India-Switzerland DTAA has remained at 10% throughout. India does not have a DTAA with another OECD country providing a lower interest rate to trigger the MFN clause for interest. The suspension of the MFN clause by Switzerland effective 1 January 2025 therefore does not affect interest taxation.

PE Attribution Disputes

Where a Swiss bank or financial institution has a PE in India (such as a branch or representative office), Indian tax authorities may argue that interest income from certain Indian debt investments is attributable to that PE and should be taxed at corporate rates under Article 7, rather than at the 10% withholding rate under Article 11. The key question is whether the specific debt-claim generating the interest is "effectively connected" with the Indian PE.

Practical Examples and Calculations

Example 1: Swiss Bank ECB to Indian Company

A Swiss bank (regulated by FINMA) extends a USD 20 million ECB to an Indian infrastructure company at 5% annual interest. Annual interest payment: USD 1,000,000.

• Domestic rate: 20% = USD 200,000 (plus surcharge and cess)
• DTAA rate (Article 11(2)): 10% = USD 100,000
• Tax saving under DTAA: USD 100,000 per year

The Swiss bank provides TRC, Form 10F, and beneficial ownership declaration. The Indian company deducts TDS at 10% and remits USD 900,000. The ECB must comply with RBI all-in-cost ceiling guidelines.

Example 2: Swiss Parent Intercompany Loan to Indian Subsidiary

A Swiss pharmaceutical company lends CHF 10 million to its Indian subsidiary at 6% interest. Annual interest payment: CHF 600,000.

• Domestic rate: 20% = CHF 120,000 (plus surcharge and cess)
• DTAA rate (Article 11(2)): 10% = CHF 60,000
• Tax saving under DTAA: CHF 60,000 per year

The interest rate must be at arm's length. If Indian transfer pricing authorities determine the arm's length rate is 4%, only interest on 4% qualifies for the treaty rate; the excess 2% may be treated as a deemed distribution or denied deduction under Section 37.

Example 3: NRI with NRO Fixed Deposit

A Switzerland-resident NRI has an NRO fixed deposit of INR 50,00,000 with an Indian bank earning 7% interest. Annual interest: INR 3,50,000.

• Domestic rate: 20% (Section 195) = INR 70,000
• DTAA rate (Article 11(2)): 10% = INR 35,000
• Tax saving under DTAA: INR 35,000 per year

The NRI furnishes TRC from the Swiss cantonal authority, Form 10F, and self-declaration to the Indian bank. The bank deducts TDS at 10% instead of 20%. In Switzerland, the NRI declares the gross interest income and claims Foreign Tax Credit for the 10% Indian tax paid.

Frequently Asked Questions

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

The treaty provides a uniform rate of 10% on the gross amount of interest under Article 11(2). Unlike some other Indian DTAAs, there is no differentiation between bank interest and general interest. Interest on loans made or guaranteed by the EXIM Bank of India or equivalent Swiss institutions is completely exempt under Article 11(3).

Is the interest rate affected by the MFN clause suspension?

No. The MFN clause suspension by Switzerland effective 1 January 2025 only affects dividends (reverting from 5% to 10%). The interest rate has always been 10% under the treaty, and no lower rate was available through the MFN clause for interest.

Does the 10% rate apply to NRO fixed deposit interest?

Yes. Interest earned on NRO fixed deposits by Swiss-resident NRIs qualifies for the 10% DTAA rate under Article 11(2), provided the NRI furnishes a valid TRC from the Swiss cantonal authority and files Form 10F. The Indian bank deducts TDS at 10% instead of the domestic 20% rate.

What happens if intercompany interest exceeds the arm's length rate?

Under Article 11(5), if the interest paid exceeds the arm's length amount due to a special relationship between the parties, only the arm's length portion qualifies for the 10% treaty rate. The excess is taxed under domestic law and may be denied deduction by Indian transfer pricing authorities.

Are guarantee fees treated as interest under this treaty?

Generally, no. Indian courts have typically held that guarantee fees paid by an Indian subsidiary to its Swiss parent for guaranteeing third-party loans are a separate service, not "interest" under Article 11. However, fees embedded in an overall lending arrangement may be treated as part of the interest cost.

Is the MLI Principal Purpose Test applicable to interest income?

Yes. Both India and Switzerland have signed the MLI. The Principal Purpose Test (PPT) may deny treaty benefits on interest income if the principal purpose of an arrangement is to obtain the reduced 10% rate without genuine commercial substance. Back-to-back lending structures through Swiss conduit entities are particularly vulnerable to PPT challenge.

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

Provide a valid Tax Residency Certificate from the Swiss cantonal authority, 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.
