Multilateral Instruments (MLI) – Decoded

1. Introduction: The Genesis of the Multilateral Instrument

Primarily, the Multilateral Instrument (MLI) is a child of the OECD’s Base Erosion and Profit Shifting (BEPS) Project. It was conceived to introduce consistency, clarity, transparency, and operational flexibility within a compressed timeframe, simultaneously modifying over 3,000 existing bilateral tax treaties worldwide.

A tax treaty represents an agreement between sovereign jurisdictions designed to eliminate double taxation and resolve conflicts arising from overlapping tax jurisdictions. As acknowledged by the OECD, “abuse of tax treaties is an important source of BEPS”. Bilateral renegotiation of thousands of independent conventions by individual governments is an extraordinarily cumbersome and time-consuming undertaking that would span decades.

Under Action Plan 15 of the OECD/G20 BEPS Project, participating nations explored the feasibility of a single multilateral convention. Its core mandate is to “modify existing bilateral tax treaties solely in order to swiftly implement the tax treaty measures developed in the course of the OECD/G20 BEPS Project”, decisively terminating treaty shopping and systemic treaty abuse.

2. Covered Tax Agreement (CTA): The Principle of Mutual Notification

A Covered Tax Agreement (CTA) is defined as a bilateral tax treaty in force between signatories to the MLI where both contracting states have explicitly notified the OECD Depository that they wish to modify that agreement through the MLI framework.

If only one treaty partner notifies an agreement while the counterparty does not, the bilateral treaty fails the dual-notification test, ceases to be a CTA, and remains unaffected by MLI provisions:

4. Historical Timeline & Entry into Force Milestones

The journey of the MLI unfolded through pivotal international milestones from February 2013 to its formal entry into force on July 1, 2018:

5. The Five Structural Pillars of the MLI Framework

The legal architecture of the MLI is structured around five operational building blocks:

6. Effective Dates: Entry into Force vs. Entry into Effect (India-Canada Benchmark)

Articles 34 and 35 govern two critical dates: Entry into Force (EIF) (when the convention becomes binding international law) and Entry into Effect (EIE) (when withholding taxes and other taxes are actually impacted):

8. India’s MLI Trajectory: 93 Notified DTAAs & 46 Effective CTAs

India actively signed the MLI on June 7, 2017 in Paris and deposited its Instrument of Ratification with the OECD on June 25, 2019. India maintains comprehensive DTAAs with 96 countries, of which it notified 93 treaties as CTAs.

As of June 29, 2021, 65 of India’s treaty partners had deposited their ratifications. However, China, Germany, Oman, Switzerland, and Mauritius omitted India from their CTA notifications. Consequently, tax treaties with these five nations remain unmodified by the MLI.

10. Comprehensive Interplay: Domestic GAAR vs. MLI Principal Purpose Test (PPT)

While domestic General Anti-Avoidance Rules (GAAR) under Chapter X-A of the Income-tax Act, 1961 took effect from AY 2018-19, the MLI introduces the Principal Purpose Test (PPT). Crucial statutory distinctions between both anti-abuse frameworks are detailed below:

12. Impact on Withholding Taxes u/s 195 & Six Mandatory Compliance Documents

Post-MLI withholding tax rules became operational in India from 1st April 2020 for all ratified CTAs. Whenever a resident payer makes a cross-border payment to a non-resident, Section 195 of the Income-tax Act is triggered.

Under Section 90, taxpayers may choose the more beneficial provisions between domestic law and the applicable DTAA. Prior to MLI, obtaining a Tax Residency Certificate (TRC) and Form 10F was widely regarded as sufficient. In the post-MLI era, standard TRC documentation is legally inadequate. Payers must exercise professional due diligence; failure to do so results in TDS default under Section 201, expense disallowance under Section 40(a)(i), and punitive penalties under Sections 221 and 271C.

13. Conclusion: Global Realignment & Equitable Taxation

India’s active leadership in implementing the BEPS project has spearheaded a historic transformation in cross-border taxation. With over 50 treaty partners having deposited their ratifications, international tax treaties are progressively evolving into modern Covered Tax Agreements.

The global implementation of the MLI symbolizes victory over artificial treaty abuse, double non-taxation, and base erosion. Premier MNEs are comprehensively restructuring operational models to align with commercial substance. In doing so, the MLI fulfills its cardinal promise: guaranteeing that sovereign nations collect an equitable share of corporate tax revenues directly commensurate with true economic activity conducted within their borders.
