Interest Tax Rate Between India and Ireland Under DTAA

Quick answer: Under Article 11 of the India-Ireland 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). A narrower 0% exemption under Article 11(3) applies only to interest derived and beneficially owned by, or connected with a loan guaranteed or insured by, government bodies and a short list of named institutions -- the Reserve Bank of India and five other Indian development-finance institutions, and the Central Bank of Ireland. Ordinary commercial bank lending is taxed at 10%, not 0%.

Key takeaways:

• General interest is capped at 10% under Article 11(2), versus 20% domestically
• A 0% exemption exists under Article 11(3), but only for two narrow limbs -- not all banks or financial institutions
• Ordinary Irish commercial bank lending is taxed at 10%, never 0%, unless guaranteed or insured by a qualifying body
• Domestic rupee/NRO interest of non-residents is taxed at rates in force (30%/35%); the 20% figure is scoped to foreign-currency borrowings
• Treaty effective in India from 1 April 2002; the India-Ireland DTAA is an MLI Covered Tax Agreement

Interest Tax Rate Between India and Ireland

The India-Ireland Double Taxation Avoidance Agreement (DTAA), signed 6 November 2000 and effective in India from 1 April 2002, provides meaningful relief on interest income between the two countries. Under Article 11, the maximum withholding tax on interest is capped at 10% of the gross amount, compared to India's domestic rate of 20% under section 207(1) of the Income-tax Act, 2025.

Interest flows between India and Ireland arise from corporate lending, bonds, government securities, and inter-company financing, including financing routed through Irish special purpose entities. The treaty's interest exemption is narrower than it first appears: it is not a general carve-out for banks or financial institutions, but a targeted exemption for government and named-institution lending. Getting this distinction right matters, because applying 0% where only the 10% rate is available is a common and costly documentation error.

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, interest paid to a non-resident on money borrowed in foreign currency is taxed at 20% (plus applicable surcharge and cess). This 20% figure is scoped to foreign-currency debt; interest on rupee-denominated borrowings and NRO deposits owed to non-residents falls outside it and is taxed at the domestic rates in force instead -- 30% for individuals and HUFs, 35% for foreign companies (FY 2024-25 onward).

DTAA Rate (With Treaty)

Article 11(2) restricts the source state's right to tax interest to a maximum of 10% of the gross amount, provided the recipient is the beneficial owner. This is a flat rate that applies regardless of whether the interest is on a secured loan, a bond, a debenture, or a government security.

The Article 11(3) Exemption -- Dual-Limb, Not a Blanket Carve-Out

Article 11(3) provides a full exemption from source-state tax, but only where the interest is derived and beneficially owned by, OR derived in connection with a loan or credit extended, guaranteed or insured by, one of two limbs: (a) the Government, a political sub-division, a statutory body or a local authority of the other Contracting State; or (b) on the India side, the Reserve Bank of India, IFCI, IDBI, the Export-Import Bank of India, the National Housing Bank, SIDBI or ICICI, and on the Ireland side, the Central Bank of Ireland; or (c) any other institution the competent authorities agree to add. Because the exemption also reaches loans merely guaranteed or insured by one of these bodies, a loan from a private lender can still qualify for 0% if it carries a qualifying government guarantee or insurance -- but ordinary, unguaranteed commercial bank lending is taxed at the 10% general rate, not 0%.

Effective Tax Savings

An Irish bank lending EUR 8 million to an Indian company at 5% interest generates EUR 400,000 in annual interest. The DTAA saves EUR 40,000 per year in withholding tax (10% instead of 20%) -- and if the loan is guaranteed by an eligible body, the interest is exempt entirely.

Who Qualifies for the Reduced Rate

Beneficial Ownership Requirement

The recipient must be the beneficial owner of the interest, with the unrestricted right to use and enjoy it. A back-to-back arrangement where an Irish entity borrows from a third country and on-lends to India, retaining no real economic risk, is unlikely to satisfy this test.

Tax Residency Requirement

The lender must be a tax resident of Ireland under Article 4, evidenced by a Tax Residency Certificate from the Irish Revenue Commissioners.

Anti-Abuse: MLI Principal Purpose Test

Because the India-Ireland DTAA is a Covered Tax Agreement under the MLI (Ireland from 1 May 2019, India from 1 October 2019), the Principal Purpose Test applies to Article 11 benefits, alongside India's domestic GAAR. There is no MFN clause in this treaty, so a more generous interest exemption from a different Irish treaty cannot be imported here.

No Permanent Establishment Connection

The reduced rate and the Article 11(3) exemption do not apply if the Irish lender has a PE in India and the debt-claim generating the interest is effectively connected with that PE. In that case, the interest is taxed as business profits under Article 7.

Interest-Specific Treaty Provisions Under Article 11

Definition of Interest (Article 11(4))

"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, including government securities, bonds, and debentures.

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 state -- the residence country's primary right to tax.

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

The source state also has the right to tax, but the tax on the beneficial owner shall not exceed 10% of the gross amount.

Article 11(3): The Exemption

As set out above, the dual-limb exemption reaches government, statutory-body, and local-authority interest, plus interest from named institutions or from loans they guarantee or insure.

Article 11(5): PE Exception

Where the beneficial owner carries on business in the other state through a PE, and the debt-claim is effectively connected with it, Articles 11(1) and 11(2) do not apply -- Article 7 governs.

Article 11(6): Source Rule

Interest is deemed to arise in a Contracting State when the payer is that state, a political subdivision, a local authority, or a resident of that state.

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 qualifies for treaty benefits; the excess is taxable under each state's domestic law, subject to transfer pricing rules.

Documentation Required to Claim the Reduced Rate

Tax Residency Certificate (TRC)

A TRC from the Irish Revenue Commissioners is required under 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 must be filed electronically if the TRC lacks the prescribed particulars; an Indian PAN is not mandatory, as a non-PAN filing route exists.

Evidence for the Article 11(3) Exemption

Where 0% is claimed, the lender should retain evidence identifying the qualifying government body, statutory body, local authority, or named institution -- or, for a guaranteed/insured private loan, the underlying guarantee or insurance instrument and the identity of the guarantor.

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 TDS at 10%, 0% where the Article 11(3) exemption is documented, or 20% (or the rates in force for rupee borrowings) if treaty documentation is missing.

Forms 145 and 146

Before remitting interest to Ireland, the payer must file Form 145 electronically; for amounts exceeding INR 5 lakh, a Chartered Accountant must also certify the payment in Form 146.

Section 395(1): Lower Withholding Certificate

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

FEMA/ECB Compliance

Interest paid on external commercial borrowings from Ireland must also satisfy the FEMA borrowing framework substituted by Notification FEMA 3(R)(5)/2026-RB (in force 16 February 2026): no all-in-cost ceiling applies for ECB of three years' average maturity or more, while shorter-maturity ECB must stay within the Trade Credit ceiling of benchmark plus 300 basis points (foreign currency) or 250 basis points (rupee). The minimum average maturity period (MAMP) is three years, with a manufacturing-sector carve-out permitting ECB of one to three years up to USD 150 million outstanding. Form ECB-2 is filed through the designated AD Category-I bank within seven calendar days of the end of the month in which proceeds were received or debt servicing occurred.

Common Disputes and Documentation Risk

Characterising Loan Fees as Interest or FTS

A recurring question is whether arrangement, commitment, or facility fees charged alongside a loan are "interest" under Article 11(4) or fall instead under Article 12 as fees for technical services. Because Article 11(4) defines interest as income from debt-claims of every kind, a fee that is genuinely consideration for the debt-claim itself takes the Article 11 treatment -- the 10% cap, or the Article 11(3) exemption where the lender qualifies. Misclassifying an interest-linked fee as FTS, or vice versa, is a common source of TDS disputes on Ireland-linked financing.

Evidencing the Article 11(3) Exemption

Because the exemption is dual-limb and institution-specific, the most common documentation failure is claiming 0% for interest paid to an ordinary Irish bank with no qualifying guarantee. Payers should verify the specific named body or the guarantee instrument before applying 0%, and default to the 10% general rate if either cannot be evidenced.

Practical Examples and Calculations

Example 1: Irish Bank Loan to an Indian Company

Shamrock Capital plc, an Irish bank, lends EUR 6 million to an Indian manufacturer at 5.5% annual interest (EUR 330,000).

• Without DTAA: TDS at 20% = EUR 66,000. Net interest received = EUR 264,000.
• With DTAA: TDS at 10% = EUR 33,000. Net interest received = EUR 297,000.
• Annual saving: EUR 33,000 -- and this remains 10%, not 0%, because this is ordinary unguaranteed bank lending.

Example 2: Loan Guaranteed by an Eligible Body

An Irish private lender extends credit to an Indian importer, and the loan carries a guarantee from a statutory body of Ireland. Because Article 11(3)(a) reaches interest derived in connection with a loan or credit "extended, guaranteed or insured by" the Government, a political sub-division, a statutory body or a local authority of the other Contracting State, the interest is fully exempt from Indian withholding tax, notwithstanding that the lender itself is a private institution. The guarantee instrument and the guarantor's statutory status are what must be evidenced.

Example 3: Interest on Rupee-Denominated NRO Deposits

An Irish resident holds an NRO fixed deposit paying INR 8 lakh in annual interest. Because this is rupee-denominated interest rather than foreign-currency borrowing, section 207(1)'s 20% figure does not apply; instead, the domestic rates in force apply (30% for an individual), subject to the treaty's 10% cap under Article 11(2) being the effective ceiling once claimed with proper documentation.

Frequently Asked Questions

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

Article 11(2) caps interest withholding at 10% of the gross amount for a beneficial owner resident in the other state, versus India's domestic 20% rate on foreign-currency borrowings under section 207(1) of the Income-tax Act, 2025. A narrower 0% exemption can apply under Article 11(3) in specific government and institutional cases.

Are all Irish banks eligible for the 0% exemption?

No. The 0% exemption under Article 11(3) applies only to interest from government bodies, statutory bodies, local authorities, or a short list of named institutions (including the Central Bank of Ireland and, on the India side, the RBI and five other institutions), or to loans guaranteed or insured by one of them. Ordinary commercial bank lending is taxed at 10%.

Can a private lender's loan still qualify for the 0% rate?

Yes, if the loan is guaranteed or insured by one of the government bodies or named institutions listed in Article 11(3), even though the lender itself is a private party with no government or institutional status of its own.

Does the 20% domestic rate apply to rupee-denominated interest?

No. Section 207(1)'s 20% figure is scoped to interest on foreign-currency borrowings. Rupee-denominated interest and NRO deposit interest owed to non-residents are taxed at the rates in force -- 30% for individuals, 35% for foreign companies -- subject to the treaty cap once documentation is filed.

Does the MLI affect interest taxation under this treaty?

Yes. The India-Ireland DTAA is a Covered Tax Agreement, so the MLI's Principal Purpose Test can deny Article 11 benefits, including the 0% exemption, where obtaining the benefit was a principal purpose of the arrangement, in addition to India's domestic GAAR.

What documentation does an Irish lender need?

A Tax Residency Certificate from the Irish Revenue Commissioners, Form 41 filed electronically, and -- where 0% is claimed -- evidence of the qualifying government, statutory-body, or named-institution status, or of a qualifying guarantee or insurance backing the loan in question.
