What protects a Japanese investor in India today: the CEPA investment chapter and the tax treaty

The India-Japan Comprehensive Economic Partnership Agreement (CEPA), signed at Tokyo on 16 February 2011, has its own investment chapter, Chapter 8, and the Department of Economic Affairs register of bilateral investment treaties (BITs) lists no India-Japan BIT, so India's 2016 and 2017 BIT terminations appear not to have touched it. Chapter 8 gives national and most-favoured-nation treatment, the customary minimum standard, protection against uncompensated expropriation and free transfers, with arbitration after six months of consultation and within three years of knowing of the loss. Taxation sits outside the CEPA: the India-Japan Double Taxation Avoidance Agreement (DTAA), as amended in 2006 and 2015, caps source-state tax on dividends, interest and royalties at 10 per cent of the gross amount for a beneficial owner.

Which instruments protect a Japanese investor?

Two instruments do the work. The CEPA, signed at Tokyo on 16 February 2011 (Ministry of External Affairs (MEA) record), carries an investment chapter with investor-State arbitration. The DTAA, signed at New Delhi on 7 March 1989 and amended by protocols of 24 February 2006 and 11 December 2015, fixes how much tax India may charge at source on what flows back to Japan. Article 10 of the CEPA keeps taxation measures outside the agreement unless it provides otherwise, and a tax convention prevails over the CEPA where the two conflict.

This note reads the CEPA text and the two protocols as published by the MEA, and the Department of Economic Affairs (DEA) register. We have not read the 1989 convention itself, which we did not find in the MEA treaty database.

What does Chapter 8 of the CEPA cover?

Article 3 of the CEPA defines "investments" as every kind of asset owned or controlled by an investor, including an enterprise or branch, shares, bonds and loans, contract rights, intellectual property, goodwill, concessions, licences and permits, and land. A note adds that an asset lacking the characteristics of an investment (commitment of capital, expectation of gain or profit, assumption of risk) is not one.

Article 83 applies the chapter to measures of central, regional and local governments (Article 84), and a note extends it to investments made before the agreement entered into force. Two conditions narrow it. Under Article 83(2), an investor whose investment was not made in compliance with the host Party's laws and regulations consistent with the agreement cannot submit a dispute to conciliation or arbitration. Under Article 11(7), after notification and consultation, a Party may deny the chapter's benefits to an enterprise with no substantial business activities in the other Party that is owned or controlled by an investor of a non-Party or of the denying Party.

What treatment does a Japanese investor receive?

Article 85 gives national treatment, and Article 86 most-favoured-nation treatment as to management, operation, use and sale of investments. Under Article 85(2), a State government's treatment is measured against the most favourable treatment it gives to investors of its own Party.

Article 87(1) promises fair and equitable treatment and full protection and security. A note says this prescribes the customary international law minimum standard of treatment of aliens and requires nothing beyond it. Article 87(2) adds that each Party shall observe any obligation it has entered into with regard to investment activities of the other Party's investors. Article 88 gives access to courts and tribunals on national treatment terms.

Article 89 bars performance requirements such as export levels, domestic content and technology transfer. Article 90 saves existing non-conforming measures listed in Annex 8 and sectors listed in Annex 9, and excludes government procurement from Articles 85, 86 and 89.

Article 92 bars expropriation, and measures tantamount to it, except for a public purpose, without discrimination, by due process of law and on prompt, adequate and effective compensation. Compensation is fair market value when the expropriation was publicly announced or occurred, whichever is earlier, with interest at a commercial rate. The article is read with Annex 10. Article 94 guarantees free transfer of capital, profits, dividends, royalties, interest and sale proceeds, but a Party may delay a transfer through non-discriminatory application of laws on insolvency, securities dealing, criminal offences, judicial orders and social security. Article 97 permits temporary measures in a balance-of-payments difficulty.

How does an investor reach arbitration?

Article 96 covers a dispute between a Party and an investor of the other Party who has incurred loss by reason of an alleged breach of Chapter 8. The investor first asks in writing for consultation or negotiation. If the dispute is unresolved six months from that request, Article 96(4) lets the investor choose conciliation or arbitration under the Convention on the Settlement of Investment Disputes between States and Nationals of Other States (ICSID Convention) while it is in force between the Parties, otherwise the Additional Facility Rules of the International Centre for Settlement of Investment Disputes, or the rules of the United Nations Commission on International Trade Law, or other rules the disputing Party agrees. Article 96(7) requires written notice of intent at least 90 days before submission, and Article 96(8) records each Party's consent.

Three limits matter. No claim may be submitted more than three years after the investor knew, or should first have known, of the loss (Article 96(9)). An investor that has gone to a domestic court or tribunal cannot go to arbitration unless it withdraws within 30 days of filing (Article 96(6)). And interim injunctive relief not involving damages may still be sought in the host State's courts (Article 96(10)).

The tribunal has three members unless the parties agree otherwise, and the presiding arbitrator may not be an Indian or Japanese citizen or resident (Article 96(11) and (12)). The award is limited to monetary damages with interest, or restitution of property with damages in lieu, plus costs, and is final and binding (Article 96(18) and (19)). The tribunal may not order attachment or enjoin the measure (Article 96(17)). Where the respondent relies on the security exception, the tribunal does not review the measure's merits.

Chapter 14 is separate. It governs disputes between the two Governments over the CEPA: consultation within 30 days of a request, and an arbitral tribunal if consultation fails within 60 days (Articles 133, 134 and 136). We found no clause disapplying it to Chapter 8.

Did the 2016 and 2017 terminations touch it?

The DEA register lists agreements by counterparty with a signature date, an entry-into-force date and, where one applies, a termination date. We read all ten pages of the register as updated on 26 October 2026. Japan does not appear on any of them. Many other entries carry termination dates between 2016 and 2021, for example the Netherlands on 1 December 2016.

On that record India has no BIT with Japan, so there was none to terminate, and the MEA database shows the CEPA with a signature date and no termination. Chapter 8 survives termination of the CEPA for ten years for earlier investments (Article 101), and either Party may end the CEPA on one year's written notice (Article 147). We have not seen a Government statement addressed to the CEPA, so the conclusion rests on the register and the text.

What does the tax treaty cap?

The 2006 protocol replaced paragraph 2 of each of Article 10 (dividends), Article 11 (interest) and Article 12 (royalties and fees for technical services) of the 1989 convention. In each case the source State may tax, but if the recipient is the beneficial owner the tax shall not exceed 10 per cent of the gross amount.

The 2015 protocol, which the MEA record shows as signed on 11 December 2015 and in force from 29 October 2016, replaced paragraphs 3 and 4 of Article 11. Interest arising in one State is taxable only in the other where it is derived and beneficially owned by that other State's Government, local authority, central bank or wholly owned financial institution, or by a resident on debt-claims guaranteed, insured or indirectly financed by those bodies. For Japan the listed institutions include the Bank of Japan and the Japan Bank for International Cooperation. The same protocol also added assistance in collecting revenue claims.

How does this look in figures?

An illustration. The facts are hypothetical. A Japanese manufacturer owns all the shares in an Indian subsidiary that has a plant under a State allotment.

Tax side, for one year: the subsidiary pays the parent, as beneficial owner, a dividend of INR 20 crore, interest of INR 10 crore and a royalty of INR 5 crore. At the treaty caps India's tax at source is at most INR 2 crore, INR 1 crore and INR 50 lakh, INR 3.5 crore in all. Interest paid instead to the Japan Bank for International Cooperation would be taxable only in Japan. The figures apply the treaty caps only.

Claim side: the State cancels the allotment and the parent knows of the loss on 1 March 2027.

What remains unsettled?

Three points. First, the annexes: Annexes 8, 9 and 10 fix the reserved sectors and how Article 92 is read, and we have not read them, so the chapter's reach against a particular State measure is open on this record.

Second, whether a tax measure can found a claim. Article 10 of the CEPA applies only Articles 4, 6 and 9 to taxation measures, so on the words an expropriation claim built on a tax assessment looks outside Chapter 8. We have not seen a tribunal or court read it.

Third, the register inference: neither the register nor the MEA record says in terms that the terminations left the CEPA untouched.
