Interest Tax Rate Between India and Belgium Under DTAA

Quick answer: Under the India-Belgium DTAA (signed at Brussels on April 26, 1993, in force from October 1, 1997), bank loan interest is taxed at a maximum of 10% and all other interest at 15% — both well below India's 20% domestic withholding rate. The preferential 10% rate is reserved for institutional bank lending, while other cross-border interest falls under the general 15% cap.

Key takeaways:

• Signed at Brussels on April 26, 1993; in force from October 1, 1997.
• Bank loan interest capped at 10% (Article 11(2)(a)).
• All other interest capped at 15% (Article 11(2)(b)).
• Both rates undercut India's 20% domestic withholding rate.
• A later protocol (March 9, 2017) updated information-exchange provisions.

Interest Tax Rate Between India and Belgium

The Double Taxation Avoidance Agreement (DTAA) between India and Belgium provides differentiated withholding tax rates on cross-border interest income. Unlike many DTAAs that apply a single rate, the India-Belgium treaty distinguishes between bank loan interest (10%) and all other interest (15%), offering preferential treatment for institutional bank lending.

Originally signed at Brussels on April 26, 1993, the treaty entered into force on October 1, 1997, and was further amended by Notification S.O. 54(E) of January 19, 2001 (lowering the royalty/FTS rate to 10%), with a later protocol signed on March 9, 2017 (in force June 26, 2025) replacing the exchange-of-information and assistance-in-collection articles. This article provides a comprehensive analysis of the interest tax provisions, the dual-rate structure, qualifying conditions, and practical compliance guidance for both Indian payers and Belgian recipients.

Treaty Rate vs Domestic Rate: Detailed Comparison

Article 11 of the India-Belgium DTAA provides two distinct withholding rates for interest income, depending on the nature of the lender:

Under Indian domestic law, interest paid to non-residents is subject to TDS under section 393(2) of the Income-tax Act, 2025 (Table, Sl. No. 17; section 195 of the Income-tax Act, 1961) at 20% plus applicable surcharge and 4% health & education cess, resulting in an effective rate of approximately 20.8% to 22.88%. The DTAA rates of 10% (bank loans) and 15% (other interest) are flat rates with no additional surcharge or cess.

The dual-rate structure reflects the treaty's policy of encouraging institutional bank financing between India and Belgium. Belgian banks extending loans to Indian companies enjoy a lower tax burden compared to non-bank lenders, incentivizing formal banking channel lending.

Who Qualifies for the Reduced Rate

The reduced interest rates under the India-Belgium DTAA are subject to several qualifying conditions:

Beneficial Ownership Requirement

The recipient must be the beneficial owner of the interest income. This means the Belgian entity receiving the interest must have the right to use and enjoy the income independently, without being contractually or legally bound to pass it on to a third party. In the context of syndicated loans or sub-participation arrangements, the beneficial ownership of each participating bank or lender must be established independently.

Bank vs. Non-Bank Classification

The 10% rate applies specifically to interest on loans granted by a bank. The term "bank" is not defined in the treaty; in practice the classification follows regulated banking status. Belgian credit institutions licensed and supervised by the National Bank of Belgium (Banque Nationale de Belgique/Nationale Bank van Belgie) and the ECB qualify for the lower 10% rate. Non-bank financial institutions, corporate lenders, and individual lenders are subject to the higher 15% rate.

Tax Residency in Belgium

The interest recipient must be a tax resident of Belgium under Article 4 of the treaty. A Tax Residency Certificate (TRC) issued by the Belgian tax authorities (Service Public Federal Finances / FOD Financien) is required to establish residency.

No PE Connection

The debt-claim giving rise to the interest must not be effectively connected with a permanent establishment (PE) or fixed base that the Belgian resident maintains in India. If the loan is connected with an Indian PE, the interest income falls under Article 7 (business profits) and is taxed accordingly.

Arm's Length Interest Rates

Under Article 11(6), if the interest paid exceeds the arm's length amount due to a special relationship between the payer and the beneficial owner, the treaty rate applies only to the arm's length portion. The excess is taxed under the domestic laws of each state. This provision is relevant for related-party loans, where transfer pricing scrutiny applies.

Interest-Specific Treaty Provisions

Article 11 of the India-Belgium DTAA contains several important provisions:

Definition of Interest

Under Article 11(3), "interest" 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. It includes income from government securities, bonds, and debentures, including premiums and prizes attaching to such securities.

Source Rule

Interest is deemed to arise in a Contracting State when the payer is a resident of that State. If the payer has a PE in the other State and the interest-bearing debt was incurred in connection with that PE, the interest is deemed to arise in the State where the PE is situated.

MFN Clause Application

The Protocol to the India-Belgium DTAA includes a Most Favoured Nation (MFN) clause. If India subsequently enters into a treaty with a third OECD member country that provides a lower rate on royalties or fees for technical services, the same lower rate automatically applies under the India-Belgium treaty. While the MFN clause specifically references royalties and FTS, its existence reflects the treaty's framework of ensuring competitive tax treatment.

2017 Protocol Enhancements

The Amending Protocol signed on March 9, 2017 (in force June 26, 2025; CBDT Notification No. 160/2025) replaced two articles:

• Article 26 -- Exchange of Information, extended to taxes of every kind, with bank secrecy no longer a ground for refusing information
• Article 27 -- Assistance in the collection of taxes between the two countries

It made no change to the interest rates or any other withholding provision.

Documentation Required

To apply the reduced DTAA rates on interest payments to Belgian residents, the following documentation is required:

Tax Residency Certificate (TRC)

A valid TRC from the Belgian tax authorities confirming that the recipient is a tax resident of Belgium under Article 4 of the DTAA. This is mandated by section 159(8) of the Income-tax Act, 2025 (section 90(4) of the Income-tax Act, 1961).

Form 41 (formerly Form 10F)

Form 41 containing prescribed details: status (company, bank, etc.), nationality/country of incorporation, tax identification number, residential status period, and address in Belgium.

Bank Confirmation (for 10% rate)

If claiming the lower 10% rate applicable to bank loans, the Belgian entity must provide documentation confirming its status as a regulated bank. This could include a banking license or regulatory certificate from the National Bank of Belgium.

Loan Agreement

A copy of the loan agreement showing the lender, the nature of the debt-claim, and key terms. For the 10% tier this evidences that the loan was granted by a bank; it also supports the arm's length analysis for related-party loans.

Self-Declaration

A self-declaration confirming beneficial ownership of the interest, that the debt-claim is not connected with a PE in India, and that the interest does not exceed arm's length amounts.

Withholding Procedure for Indian Payers

Indian entities making interest payments to Belgian recipients must follow specific compliance procedures:

Section 393(2) TDS Deduction

Tax must be deducted under section 393(2) at the time of credit to the payee's account or at the time of payment, whichever is earlier. The applicable rate depends on the classification:

• Belgian bank: 10% DTAA rate
• Other Belgian entity: 15% DTAA rate
• Documentation incomplete: 20% domestic rate + surcharge + cess

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

Before remitting interest payments to Belgium:

• Obtain Form 146 from a Chartered Accountant, certifying the nature of payment, applicable DTAA article, and rate of TDS
• File Form 145 online as a remittance declaration

The authorized dealer bank requires Form 145 acknowledgment before processing outward remittance under FEMA regulations.

ECB Compliance

If the interest relates to an External Commercial Borrowing (ECB) from a Belgian bank, additional FEMA and RBI ECB regulations must be complied with. Under Notification FEMA 3(R)(5)/2026-RB (in force 16 February 2026), ECB with an average maturity of three years or more carries no all-in-cost ceiling and is priced in line with prevailing market conditions; only ECB with an average maturity below three years is capped, at the Trade Credit ceiling of benchmark rate + 300 bps (foreign currency ECB) or + 250 bps (rupee ECB). End-use monitoring continues to apply, and 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.

TDS Returns

File quarterly TDS returns in Form 144 (formerly Form 27Q) reflecting the tax deducted on payments to non-residents.

Common Disputes and Judicial Precedents

Interest taxation under the India-Belgium DTAA has been subject to several interpretive disputes:

Bank Classification Disputes

The distinction between the 10% bank rate and 15% general rate has led to disputes over what constitutes a "bank." Belgian financial institutions that are not traditional banks but perform banking functions (such as investment banks or specialized lending institutions) may face challenges in claiming the lower 10% rate. The classification generally follows Belgian regulatory definitions.

Sofina S.A. Case Implications

The Sofina S.A. vs. ACIT (ITAT Mumbai) ruling, while primarily about capital gains, established important precedents for the India-Belgium DTAA. The ITAT ruled in favor of the Belgian taxpayer, reinforcing the principle that treaty benefits should be available to genuine Belgian residents with economic substance, and that the burden of proving treaty abuse lies with the tax department.

Interest vs. Business Profits

When a Belgian bank operates through a branch (PE) in India, disputes arise over whether interest income earned by the Belgian head office on loans to Indian clients is taxable as interest under Article 11 or as business profits under Article 7 attributable to the Indian PE. The determination depends on whether the lending activity is conducted through the Indian branch or directly by the head office.

Thin Capitalization and Transfer Pricing

Indian tax authorities may challenge the quantum of interest paid to Belgian related-party lenders under transfer pricing provisions in section 161 of the Income-tax Act, 2025 (section 92 of the Income-tax Act, 1961) if the interest rate exceeds arm's length benchmarks. While there are no specific thin capitalization rules in India, the arm's length provision in Article 11(5) and domestic transfer pricing rules serve a similar function.

Accrual vs. Payment for TDS Timing

Disputes arise over whether TDS on interest to Belgian entities is triggered at the time of credit (accrual) or payment. Section 393(2) mandates deduction at the earlier of credit or payment, and courts have consistently upheld this interpretation.

Practical Examples and Calculations

The following examples illustrate how the India-Belgium DTAA interest provisions work in practice:

Example 1: Belgian Bank ECB to Indian Company

KBC Bank (Belgium) extends an ECB of EUR 20 million to an Indian pharmaceutical company at 4.5% annual interest. Annual interest: EUR 900,000 (approximately INR 8.10 crore).

• Without DTAA: TDS at 20% + 2% surcharge + 4% cess. Effective rate approximately 21.216%. Tax: ~INR 1,71,85,000
• With DTAA (bank rate): TDS at 10% flat. Tax: INR 81,00,000
• Annual savings: approximately INR 90,85,000

Example 2: Belgian Corporate Lender (Non-Bank)

A Belgian multinational company lends EUR 5 million to its Indian subsidiary at 6% annual interest. Annual interest: EUR 300,000 (approximately INR 2.70 crore).

• Without DTAA: TDS at 20% + 2% surcharge + 4% cess. Effective rate approximately 21.216%. Tax: ~INR 57,28,000
• With DTAA (non-bank rate): TDS at 15% flat. Tax: INR 40,50,000
• Annual savings: approximately INR 16,78,000

Note: The non-bank rate of 15% provides a smaller but still meaningful saving compared to the bank rate of 10%.

Example 3: Belgian NRI with Indian Fixed Deposit

A Belgian tax resident (Indian-origin) holds an NRO fixed deposit of INR 1,00,00,000 at 7.5% interest. Annual interest: INR 7,50,000.

• Without DTAA: TDS at 30% + 4% cess = 31.2% (rate for NRO interest of an individual). Tax: INR 2,34,000
• With DTAA (non-bank rate): TDS at 15%. Tax: INR 1,12,500
• Savings: INR 1,21,500 annually

The Belgian resident can claim a foreign tax credit in Belgium for the 15% tax withheld in India under Article 23 of the treaty.

Example 4: Restructuring for Better Rate

An Indian company needs EUR 10 million. It can borrow from:

• Option A: Belgian parent company directly (non-bank rate: 15%)
• Option B: Belgian parent routes the loan through a Belgian bank (bank rate: 10%)

By structuring the borrowing through a Belgian bank, the Indian company saves 5% in withholding tax on each interest payment. However, the bank's lending margin and arrangement fees must be factored in to determine the net benefit.

Frequently Asked Questions

What are the interest tax rates between India and Belgium under the DTAA?

The India-Belgium DTAA provides two interest rates: 10% for interest on loans granted by a bank, and 15% for all other interest. Both rates are lower than the domestic rate of 20% plus surcharge and cess. The applicable rate depends on whether the Belgian lender is a regulated bank.

Why does the India-Belgium DTAA have two different interest rates?

The dual-rate structure reflects a policy of encouraging formal banking channel lending between the two countries. The lower 10% rate for bank loans incentivizes Indian companies to borrow from Belgian banks rather than from non-bank entities, promoting regulated cross-border financing.

Is government or central-bank interest exempt under the India-Belgium DTAA?

No. Unlike many Indian treaties, Article 11 of the India-Belgium DTAA contains no exemption for interest paid to governments, central banks, or on government-guaranteed loans. Article 11(3) merely includes income from government securities within the definition of taxable interest. Every qualifying payment falls under the 10% (bank loans) or 15% (other) caps.

Can a Belgian fintech or digital bank claim the 10% bank rate?

A Belgian fintech company can claim the 10% bank rate only if it is regulated as a bank by the National Bank of Belgium. Merely performing banking-like functions without a formal banking license would not qualify. The classification follows Belgian regulatory definitions of what constitutes a bank.

How does the MFN clause affect interest taxation?

It does not. The MFN clause in the India-Belgium Protocol covers only royalties and fees for technical services. A lower interest rate agreed by India with another OECD country would not flow into the Belgium treaty -- the 10%/15% interest caps can change only through a fresh protocol.

What if a Belgian bank has a branch in India?

If a Belgian bank operates through a branch (PE) in India, interest income on loans managed through the Indian branch is taxed as business profits under Article 7, not as interest under Article 11. However, interest on loans managed directly by the Belgian head office, without connection to the Indian branch, can still benefit from the 10% treaty rate.

How can an Indian company apply the correct rate when making interest payments?

The Indian payer should collect TRC, Form 41, and supporting documentation from the Belgian recipient before the first interest payment. For Belgian banks, additionally verify the banking license. Apply the 10% rate for banks or 15% for others, and file Forms 146 and 145 before remittance. If in doubt about classification, consider requesting a lower withholding certificate under section 395(1) of the Income-tax Act, 2025 (section 197 of the Income-tax Act, 1961).
