Evaluating India’s Stock Market Tax Architecture: Analyzing LTCG Rates, STT Revenues, and Capital Outflows

Navigating global capital flows requires balancing fiscal revenue requirements against market competitiveness. In modern cross-border finance, capital functions like a free-flowing river, seeking jurisdictions with minimal frictional taxation. Under the framework codified by the Finance (No. 2) Act, 2024, India levies a 12.5% tax on long-term capital gains (LTCG) and a 20% rate on short-term capital gains (STCG) on listed equities, supplemented by statutory surcharges, health and education cesses, and a transaction-level Securities Transaction Tax (STT) applied to every market order. On July 20, 2026, the Ministry of Finance confirmed in response to Lok Sabha Unstarred Question No. 166 that foreign portfolio investors (FPIs) are subject to the same 12.5% LTCG rate as domestic residents, highlighting India’s unique stance on taxing non-resident equity returns.

Global Tax Framework Comparison and Structural Drag

India’s tax regime for non-resident portfolio investments stands in contrast to competing global jurisdictions. The United States treats capital gains realized by non-residents on listed equities as foreign-source income, applying a zero percent tax rate. Financial hubs such as Singapore, Hong Kong, and the United Arab Emirates enforce no capital gains tax. China has maintained tax exemptions for foreign investors trading A-shares through Circulars 79 and 81—originally issued on November 14, 2014—extending this treatment through December 31, 2027.

This differential taxation creates a measurable tax drag on investment yields. Historically, the Nifty index has compounded at approximately 10.5% annually in rupee terms over two decades. Factoring in holding patterns across short-term and long-term tax slabs results in an estimated blended tax drag of nearly 15% on gross returns, reducing domestic rupee compounding from 10.5% to roughly 8.9%. When combined with annual rupee depreciation averaging 4%—which escalated to nearly 7% in 2026—dollar-denominated investor returns decline to approximately 6%. Compared to the S&P 500’s century-long average annual return of around 10%, two percentage points of this performance deficit stem directly from tax design. When international investors demand higher gross returns to offset tax friction, market pricing adjusts, increasing the overall cost of equity for issuing corporations evaluated in any broader corporate earnings breakdown.

Fiscal Collections: LTCG and Transaction Tax Realities

From the perspective of tax administration and sovereign budget management, the revenue generated by capital taxation remains significant. Official exchequer figures demonstrate substantial tax collections under the equity capital gains regime:

• FY 2023-24 Equity LTCG Revenues: Totaled Rs 72,249 crore.
• FY 2024-25 Equity LTCG Revenues: Rose to Rs 1,29,158 crore.
• FY 2025-26 Securities Transaction Tax (STT): Direct collection reached Rs 57,522 crore.

The policy rationale for maintaining these levies relies partly on horizontal equity considerations. When long-term capital gains tax was reintroduced in 2018, former Finance Minister Arun Jaitley highlighted that exempt capital gains in tax returns for assessment year 2017-18 amounted to Rs 3.67 lakh crore, emphasizing the inequity of exempting capital returns while earned income faced standard taxation. However, tax compliance dynamics differ fundamentally between resident taxpayers and foreign institutional capital. While domestic capital is less mobile, non-resident funds are highly elastic, meaning transaction tax costs and gain levies alter asset allocation behaviors.

Market Flow Realities and Index Allocations

The transaction tax framework and non-resident capital gains levies coincide with notable capital flow shifts. FPIs recorded net equity sales of Rs 1.66 lakh crore in 2025, followed by a record net outflow of Rs 3.08 lakh crore in 2026 through October 12. Consequently, foreign ownership in Indian equity markets dropped to a 15-year low, while India’s weighting within the MSCI Emerging Markets index roughly halved from its peak in September 2024.

Although domestic institutional investors supported equity absorbency by purchasing equities for 38 consecutive months, foreign capital retrenchment alters benchmark allocations. Meanwhile, macroeconomic shifts, including global interest rate dynamics and the fiscal impact of inflationary pressures, further influence cross-border capital reallocation strategies.

Policy Exemptions and Compliance Reform Perspectives

The government demonstrated willingness to adjust capital tax rules under the Income-tax (Amendment) Ordinance, 2026. Effective April 1, 2026, this ordinance exempted foreign portfolio investors from interest and capital gains taxes on government securities, incurring an estimated capital gains revenue sacrifice of Rs 500 to Rs 1,000 crore to attract sovereign wealth and pension funds. This carve-out established a statutory precedent for tax parity in debt markets that differs from the treatment of corporate equity issuers, impacting baseline equity valuations and tax compliance.

To balance compliance administrative overhead with revenue collection, tax analysts point to historic frameworks. The 2004 tax compromise introduced the Securities Transaction Tax as an efficient, evasion-proof withholding mechanism designed to offset the exemption of long-term capital gains. Because STT yielded Rs 57,522 crore in 2025-26 directly at the point of trade execution, relying on transaction taxes minimizes tax leakage without complex multi-jurisdictional filing burdens. Alternatively, regulatory bodies including the Securities and Exchange Board of India (SEBI) alongside the Finance Ministry have reportedly examined proposals to allow FPIs to compute capital gains in their native investment currencies to avoid taxing currency depreciation, following public statements on October 13 by the Finance Minister inviting feedback on LTCG tax structures.
