India-Portugal DTAA: Complete Guide to the Double Taxation Avoidance Agreement

Quick answer: The India-Portugal DTAA caps dividends at 15% of the gross amount, or 10% where the beneficial owner is a company that has directly held at least 25% of the paying company's capital stock for an uninterrupted two-fiscal-year period. Interest, royalties and fees for included services are each capped at a flat 10%. Signed at Lisbon on 11 September 1998 and in force from 30 April 2000, the treaty has no MFN clause, no LOB article and no services PE test, but sets an unusual nine-month construction PE threshold. The Multilateral Instrument (MLI) has also replaced Article 13(4)'s original rule on share gains with a land-rich test, discussed below.

Key takeaways:

• Dividends: 15% general, 10% where the beneficial owner is a company holding at least 25% of the paying company's capital stock for two fiscal years
• Interest, royalties and fees for included services: flat 10% each, with no separate tier for banks or financial institutions on interest
• Interest is exempt on both sides of the transaction: where the debtor is a Contracting State, a sub-division or a local authority, and where it is paid to a State, sub-division, local authority or an institution financing under an inter-government agreement — there is no named list of institutions such as the RBI or EXIM Bank
• Fees for included services cover only technical or consultancy services, and only where they are ancillary to a royalty right or "make available" technical knowledge; managerial services fall outside Article 12 entirely
• No MFN clause, no Limitation of Benefits (LOB) article and no services PE clause anywhere in the Convention or its two Protocols
• Construction PE threshold is nine months, and a natural-resource installation or structure becomes a PE only once used for more than 120 days in a fiscal year
• The MLI (a Covered Tax Agreement for both countries) replaced Article 13(4)'s share-gains rule with a test keyed to more than 50% of value derived from immovable property in the preceding 365 days, effective for India from 1 April 2021

Overview of the India-Portugal DTAA

The Double Taxation Avoidance Agreement (DTAA) between the Republic of India and the Portuguese Republic prevents the same income from being taxed twice and guards against fiscal evasion. It was signed at Lisbon on 11 September 1998, in Hindi, Portuguese and English, with the English text prevailing in case of doubt, and entered into force on 30 April 2000.

The treaty covers taxes on income only — there is no capital or wealth-tax article. On the Portuguese side, Article 2(3)(a) lists the personal income tax (IRS), the corporate income tax (IRC) and the local surtax on IRC known as Derrama. Thirty articles and two Protocols (1998 and 2017) make up the current text, covering permanent establishment, dividends, interest, royalties and fees for included services, capital gains, employment income, and the mechanics of claiming relief.

Treaty History, Protocols and MLI Status

The Agreement was accompanied by a Protocol signed the same day, an integral part of it, which clarifies that a storage warehouse counts as a PE (Ad Article 5), caps head-office expense deductions under section 44C of the Income-tax Act, 1961 (Ad Article 7), preserves the residence State's right to tax certain capital gains (Ad Article 13), and caps any higher PE tax rate at "not more than 10%" above the domestic company rate (Ad Article 24).

India notified the Convention by GSR 542(E), dated 16 June 2000, corrected by SO 673(E), dated 25 August 2000 and GSR 597(E), dated 20 September 2005. The Convention has effect in India from the fiscal year beginning 1 April 2001 (Article 29(2)(b)), and in Portugal from the fiscal year beginning 1 January 2001 (Article 29(2)(a)).

A narrower Amending Protocol signed at Lisbon on 24 June 2017 replaced Article 26 (Exchange of Information) with current OECD-standard wording and added a data-protection paragraph. It entered into force on 8 August 2018 under Article III of that Protocol, and India notified it by S.O. 4724(E) (Notification No. 43/2018), dated 11 September 2018. It changed no rate, no PE threshold and no capital-gains rule.

Both India and Portugal ratified the OECD's Multilateral Instrument (MLI) and each listed the other, making this a Covered Tax Agreement. The MLI entered into force for India on 1 October 2019 and for Portugal on 1 June 2020, with effect in India for withholding and other taxes alike from 1 April 2021. Six MLI provisions apply, including the Principal Purpose Test (Article 7(1)), the share-gains rule at Article 9(4) (discussed below), and anti-fragmentation on the Article 5(4) exclusions. The MLI's optional corporate tie-breaker and agency-PE rule were not adopted — Article 4(3)'s place-of-effective-management test and Article 5(5)/(6) stand unmodified.

Model Basis and Distinctive Features

The India-Portugal DTAA follows a Hybrid model. The nine-month construction PE threshold, a warehouse and sales outlet listed as deemed PEs, and Article 7's limited force of attraction are UN Model hallmarks. Yet the treaty contains no services PE clause at all — an omission unusual for a UN-leaning India treaty.

Key Treaty Articles

Business Profits — Article 7

Business profits are taxable only in the enterprise's home State unless it carries on business through a permanent establishment in the other State. Where a PE exists, Article 7(1) gives the source State a limited force of attraction over similar sales and business activities in that State, even where not routed through the PE itself.

Dividends — Article 10

Dividends paid by an Indian company to a Portuguese beneficial owner are capped at 15% by Article 10(2)(b)(i), reduced to 10% under Article 10(2)(b)(ii) "if the beneficial owner is a company that, for an uninterrupted period of two fiscal years prior to the payment of the dividend, owns directly at least 25 per cent of the capital stock of the company paying the dividends." The mirror limb for Portugal-source dividends, Article 10(2)(a), reads "two years" rather than "two fiscal years" — the limbs are not word-identical, so quote the one matching the direction of the flow. There is no third tier and no exemption.

Interest — Article 11

Interest is capped at 10% under Article 11(2) — a single rate, with no separate lower tier for banks or financial institutions. Two narrow limbs reach nil. The payer-side limb, Article 11(3)(a), covers interest "if the debtor of such interest is that State, a political or administrative sub-division or a local authority thereof." The recipient-side limb, Article 11(3)(b), covers interest "paid to the other Contracting State... or an institution (including a financial institution) in connection with any financing granted by them under an agreement between the Governments of the Contracting States" — so it needs government-to-government finance, not merely a state-linked lender. Both are generic: no RBI, EXIM Bank or named development bank appears anywhere. Interest effectively connected with a PE is taxed under Article 7 or 14 instead (Article 11(5)).

Royalties and Fees for Included Services — Article 12

Article 12, titled "Royalties and fees for included services," caps both at 10% under Article 12(2). Article 12(4) defines fees for included services as payments for "technical or consultancy" services — not managerial services — that either are ancillary to a paragraph-3 right, or "make available technical knowledge, experience, skill, know-how or processes or consist of the development and transfer of a technical plan or technical design which enables the person acquiring the services to apply the technology contained therein." Article 12(5) adds seven exclusions, two of them commercially significant: (f) services for a natural-resource installation under Article 5(2)(g), and (g) services referred to in the Article 5(3) construction and supervisory paragraph. Both fall to Article 7 instead, taxable only if a PE exists.

Capital Gains — Article 13

Immovable-property gains are taxed where the property sits (13(1)); PE-asset gains where the PE sits (13(2)); ship and aircraft gains "only in the Contracting State of which the enterprise is a resident" — residence, not place of effective management (13(3)).

Paragraph 13(4) is where the MLI intervenes. The original had two sentences: one on shares in property-heavy companies, a second giving the source State an unconditional right to tax gains on any other shares in a resident company. The joint synthesised text brackets the entire paragraph, both sentences, "[Replaced by paragraph 4 of Article 9 of the MLI]." The replacement taxes gains on shares or comparable interests "if, at any time during the 365 days preceding the alienation, these shares or comparable interests derived more than 50 per cent of their value directly or indirectly from immovable property... situated in that other State" — narrower in requiring a 50% threshold over a 365-day lookback, broader in reaching comparable and indirect interests.

The consequence a reader must not skip: India's old unconditional right to tax ordinary (non-land-rich) share gains is gone. Paragraph 4 as replaced reaches only land-rich shares, so a gain on Indian shares that are not land-rich is no longer "referred to in paragraphs 1, 2, 3 and 4" and falls to the residual rule in 13(5) — taxable only in Portugal. India-side that runs from 1 April 2021, for withholding and other taxes alike; earlier alienations stay on the old two-sentence paragraph 4. Three things still bite: the MLI's Principal Purpose Test; India's General Anti-Avoidance Rule in Chapter XI of the Income-tax Act, 2025, which section 159(6) (section 90(2A) of the Income-tax Act, 1961) applies even where the treaty is more beneficial; and domestic law, which charges the gain unless the treaty claim is actually made. The Protocol's Ad Article 13 is not one of them — it gives a taxing right to the residence State, so it adds nothing for India.

Withholding Tax Rates Summary

Under section 159(4) of the Income-tax Act, 2025 (section 90(2) of the Income-tax Act, 1961), a taxpayer applies whichever rate — treaty or domestic — is more beneficial. See our dedicated withholding tax rates page for India to Portugal for the full breakdown.

Permanent Establishment Rules

Article 5 defines a PE as a fixed place of business, including places of management, branches, offices, factories, mines and other places of extraction of natural resources.

Construction PE — Nine Months

Article 5(3): "a building site, construction, installation or assembly project or supervisory activities in connection therewith constitutes a permanent establishment only if it lasts more than nine months." Nine months sits between the OECD Model's twelve-month and the UN Model's six-month thresholds — a figure worth checking carefully rather than assuming the more common six or twelve.

No Services PE

There is no furnishing-of-services clause anywhere in Article 5 — no 90-day or 183-day services-PE test. Cross-border technical fees are instead generally taxed as fees for included services under Article 12 at 10%, unless a fixed-place or agency PE independently exists.

Other Deemed PEs and Exclusions

A sales outlet is a listed PE (5(2)(f)); the 1998 Protocol's Ad Article 5 adds that a storage warehouse is a PE. A natural-resource installation is a PE "only if so used for a period of more than 120 days in a fiscal year" (5(2)(g)). Article 5(5) creates an agency PE for habitual contract-concluding authority, or habitual stock-and-delivery plus a sale contribution — no separate "habitually secures orders" limb. Article 5(7) creates an insurance PE, excluding re-insurance. The MLI's anti-fragmentation rule applies to the Article 5(4) exclusions; its agency-PE rule was not applied.

Anti-Abuse: No MFN, No LOB, MLI PPT and GAAR

Two features common in India's other European treaties are absent here: no most-favoured-nation (MFN) clause anywhere in the Convention or either Protocol, and no Limitation of Benefits (LOB) article.

Anti-abuse protection instead rests on the beneficial-ownership requirement in Articles 10(2), 11(2) and 12(2); the MLI's Principal Purpose Test, since both countries listed this as a Covered Tax Agreement; and India's domestic General Anti-Avoidance Rule (GAAR) in Chapter XI of the Income-tax Act, 2025, which section 159(6) (section 90(2A) of the Income-tax Act, 1961) applies to an assessee even where it is not beneficial to them.

Tax Residency Certificate and How to Claim Treaty Benefits

In Portugal, the Tax Residency Certificate (TRC) is issued by the Autoridade Tributária e Aduaneira (AT) through the online Portal das Finanças. Since 1 January 2022, the AT no longer stamps a foreign administration's own form; a Portuguese taxpayer instead requests a certificado de residência fiscal on the Portal and attaches it to the Indian form. An Indian payer should expect this Portal-issued PDF certificate — not a counter-signed Indian form.

To claim benefits in India, a non-resident must obtain that TRC, electronically file Form 41 (formerly Form 10F) (mandatory since 1 October 2023), and self-declare beneficial ownership and, where relevant, no PE in India. The Indian payer withholds under section 393(2) of the Income-tax Act, 2025 (Table, Sl. No. 17; section 195 of the Income-tax Act, 1961), and files Form 145 (formerly Form 15CA) before remitting; a Chartered Accountant's certificate in Form 146 (formerly Form 15CB) is needed only where the taxable remittance exceeds INR 5 lakh and no section 395 certificate has been obtained. For certainty in advance, the Portuguese payee applies for a lower or nil deduction certificate under section 395(1) of the Income-tax Act, 2025 (section 197 of the Income-tax Act, 1961); the Indian payer's own route, to have the chargeable proportion of a remittance determined, is section 395(2) (section 195(2) of the Income-tax Act, 1961). Transfer-pricing disclosures, where applicable, use Form 48 (formerly Form 3CEB). For hands-on help structuring a claim, see our DTAA advisory service.

Mutual Agreement Procedure

Article 25 provides a Mutual Agreement Procedure (MAP): a taxpayer may present a case to the competent authority of their residence State (or, under Article 24(1), nationality State) within three years of the first notification of the disputed action. Article 3(1)(i) names India's competent authority as the Central Government in the Ministry of Finance (Department of Revenue), or an authorised representative.

Worked Example

A Portuguese company holds 30% of the capital stock of its Indian subsidiary for three years. On a dividend of INR 1,00,00,000, the two-fiscal-year, 25% holding test under Article 10(2)(b)(ii) caps withholding at 10%: INR 1,00,00,000 × 10% = INR 10,00,000, against INR 20,00,000 domestically and INR 15,00,000 at the default treaty rate — so the holding-period test itself saves INR 5,00,000, and the treaty as a whole saves INR 10,00,000. If the same subsidiary instead pays INR 50,00,000 of interest to a Portuguese commercial bank (no bank tier here), Article 11(2)'s general 10% applies: INR 5,00,000 withheld. Nil needs Article 11(3)(b) — the Portuguese State, a sub-division or local authority, or an institution whose finance runs under an agreement between the two Governments. An ordinary commercial loan does not qualify.

Common Mistakes

Assuming a bank tier exists for interest

Article 11 sets a single 10% cap with no reduced rate for banks generally — only the two narrow, government-linked exemptions in 11(3) reach 0%.

Importing a broader FTS definition from another treaty

Article 12(4) covers only "technical or consultancy" services with a make-available clause; managerial services are outside Article 12 altogether.

Overlooking the 12(5)(f) and (g) carve-outs

Oilfield-installation and construction-supervision fees are excluded from Article 12 and fall to Article 7 instead, taxable only if a PE exists.

Reading the MLI capital-gains change as a blanket exemption

It is not. Land-rich shares are still taxable in India under the replaced paragraph 4, the change bites only from 1 April 2021 India-side, and the Principal Purpose Test and GAAR still apply. The Protocol's Ad Article 13 is not a counter-argument — it gives the residence State a taxing right, not India.

Citing an MFN clause or LOB article that does not exist

This treaty has neither. Do not import benefit language from another country's treaty.

Frequently Asked Questions

What is the India-Portugal DTAA?

The India-Portugal DTAA is a tax treaty signed on 11 September 1998 and in force since 30 April 2000 that prevents the same income from being taxed twice in India and Portugal. It caps withholding on dividends, interest, and royalties/fees for included services, sets rules for permanent establishments and capital gains, and provides a mutual agreement procedure for resolving disputes between the two tax administrations.

What is the withholding tax rate on dividends under the India-Portugal DTAA?

Dividends are capped at 15% of the gross amount under Article 10(2)(b)(i). The rate drops to 10% under Article 10(2)(b)(ii) if the beneficial owner is a company that has directly owned at least 25% of the paying company's capital stock for an uninterrupted period of two fiscal years before the dividend is paid.

Does the India-Portugal DTAA have a services permanent establishment clause?

No. Unlike many of India's other tax treaties, Article 5 contains no 90-day or 183-day services PE test. Cross-border technical and consultancy fees are instead generally taxed as fees for included services under Article 12 at 10%, unless a fixed-place or agency PE independently exists under the treaty's other tests.

How has the MLI changed capital gains taxation under this treaty?

The Multilateral Instrument replaced the whole of Article 13(4), including India's earlier unconditional right to tax ordinary share gains, with a test that applies only where the shares derived more than 50% of their value from immovable property at some point in the preceding 365 days. Gains on shares that are not land-rich therefore fall to the residence-only rule in Article 13(5), so India cannot tax them — for withholding where the event occurs on or after 1 April 2021, and for other taxes for periods beginning on or after that date. The Principal Purpose Test and India's GAAR still apply, and the exemption must be claimed with a Tax Residency Certificate and Form 41.

What documents are needed to claim DTAA benefits between India and Portugal?

A Portuguese resident needs a Portal-issued Tax Residency Certificate from the Autoridade Tributária e Aduaneira (via "Pedir Certidão" on the Portal das Finanças), electronically filed Form 41 (formerly Form 10F), and a self-declaration of beneficial ownership. The Indian payer must withhold at the correct rate and file Form 145 (formerly Form 15CA) before remitting payment, adding a Chartered Accountant's certificate in Form 146 only where the taxable remittance exceeds INR 5 lakh without a section 395 certificate.

Does the India-Portugal DTAA have an MFN clause or an LOB article?

No. Neither the Convention nor its 1998 or 2017 Protocols contain a most-favoured-nation clause or a Limitation of Benefits article. Anti-abuse scrutiny instead rests on the treaty's beneficial-ownership requirements, the MLI's Principal Purpose Test (both countries listed this as a Covered Tax Agreement), and India's domestic GAAR.
