How GST Impacts Your Investment Returns: What Clients Should Know

India’s Goods and Services Tax (GST) touches almost every paid service in the capital markets, but not always in obvious ways—especially when it comes to calculating true, net investment returns. For serious investors and traders, overlooking GST on brokerage, advisory, DP, or platform charges can quietly shave off basis points that add up over time, particularly in high-frequency trading or active portfolio rebalancing.

Even professional services like investment advisory and research are squarely within GST’s ambit, typically at 18%, which affects both pricing and the value received depending on whether one is an individual or a business eligible for input tax credit (ITC).

This guide breaks down exactly how GST flows through your investing journey—from order execution to advisory fees—so clients can plan smarter, reduce avoidable costs, and protect returns while complying with the rules. It’s written for informed retail investors, active traders, family offices, and SMEs who engage with the markets professionally and want a precise, operational view of GST’s impact.

GST: What It Covers in Capital Markets—and What It Doesn’t

A common misconception is that GST applies to the security you buy or sell; it doesn’t—securities are excluded from the definition of “goods,” so GST is not levied on the traded value of shares, bonds, or ETFs. Instead, GST applies to the services you consume around trading and investing—brokerage, platform charges, DP/AMC fees, and professional advisory—typically at 18%.

Practically, this means your gross return is untouched by GST, but your cost base is higher due to GST on services—reducing your net return if left unmanaged.

The Mechanics: Where You Actually Pay GST

Short version: every time a service is billed, GST likely appears somewhere in your contract note or invoice. Here’s what to watch.

1) Brokerage and Platform Execution

2) Demat and Depository Participant (DP) Charges

3) Investment Advisory and Research Services

How GST Reduces Your Net Returns—And How Much

Timely understanding of the drag is critical for traders and fee-conscious investors:

However, GST does not apply to STT or stamp duty—so if costs are mainly statutory, GST impact is smaller proportionally. For GST-registered businesses using markets for treasury operations, ITC on eligible service inputs could offset some or all GST paid on brokerage/advisory, subject to conditions. Most retail individuals cannot claim ITC.
