India and Sri Lanka Amend Tax Treaty to Prevent Misuse and Tax Evasion

By Arth Vani Desk · 2026-07-18

India has updated its Double Taxation Avoidance Agreement (DTAA) with Sri Lanka to include a new anti-abuse rule. The Principal Purpose Test (PPT) will allow tax authorities to deny treaty benefits if the primary goal of a transaction is to avoid taxes.

India is continuing its global effort to tighten tax loopholes by amending its long-standing tax treaty with Sri Lanka. The two nations have introduced a 'Principal Purpose Test' (PPT) into their Double Taxation Avoidance Agreement (DTAA). This move is designed to ensure that tax benefits are only available to genuine businesses and not used as a tool for tax evasion.

What is the Principal Purpose Test?

The PPT is a global standard aimed at curbing 'treaty shopping.' This occurs when an entity from a third country sets up a shell company in a treaty-partner nation specifically to take advantage of lower tax rates. Under the new rules, Indian tax authorities can deny treaty benefits—such as lower withholding taxes on interest or royalties—if they determine that obtaining a tax advantage was one of the main reasons for a particular business arrangement.

Timeline for Implementation

While the amendment has been formalized, it will not impact taxpayers immediately. The new rules are set to become effective for income generated starting from the Financial Year 2027-28 (FY28). This provides businesses and investors a significant window to review their existing cross-border structures and ensure they comply with the updated standards.

Why This Matters

This amendment aligns India’s tax relations with Sri Lanka with the Multilateral Instrument (MLI) and the Base Erosion and Profit Shifting (BEPS) framework developed by the OECD. By adopting these international standards, India aims to create a more transparent tax environment and prevent the loss of revenue through aggressive tax planning. For retail investors, while this primarily impacts corporate structures, it signals a broader trend of increased scrutiny on offshore investments and cross-border income.
