Union Budget 2026: STT Hiked on Derivatives, Buyback Tax Rules Overhauled, MAT Cut to 14%

Finance Minister Nirmala Sitharaman presented the Union Budget 2026-27 today, unveiling a mix of aggressive revenue-generation measures and targeted corporate relief. The announcements mark a significant shift in market taxation, with a crackdown on speculative trading through steeper Securities Transaction Tax (STT) rates, while simultaneously softening the blow for corporates with a reduction in the Minimum Alternate Tax (MAT). This “give-and-take” budget aims to curb market volatility while bolstering the “Make in India” manufacturing ecosystem.

1. F&O Trading Gets Costlier: STT Hiked

In a move clearly aimed at cooling the overheated derivatives market, the Finance Minister announced a sharp increase in the Securities Transaction Tax (STT) on Futures and Options (F&O). This decision follows growing regulatory concerns regarding retail participation in high-risk speculative trading.

Revised Rates

• Futures: The STT on the sale of futures has been more than doubled, rising to 0.05% from the previous 0.02%.
• Options: The STT on the sale of options premiums has been hiked to 0.15% from 0.10%.

Implication: This hike significantly increases the breakeven point for intraday traders and scalpers. High-frequency trading (HFT) firms and retail arbitrage strategies will face squeezed margins, potentially leading to a short-term consolidation in trading volumes on the NSE and BSE.

2. Major Shift in Share Buyback Taxation

The Budget 2026 has fundamentally altered how share buybacks are taxed, closing a popular arbitrage route used by companies to distribute surplus cash in a tax-efficient manner compared to dividends.

New Capital Gains Treatment

• Shareholders: Proceeds from share buybacks will now be taxed as capital gains for all categories of shareholders. This aligns the tax treatment of buybacks with that of dividend income, ensuring that investors pay tax based on their realized gains.
• Promoters: To further discourage tax avoidance strategies, promoters will now be required to pay an additional tax on share buybacks.

Context: Previously, companies paid a buyback tax, and the income was tax-free in the hands of shareholders. The new regime shifts the burden, ensuring that high-net-worth individuals (HNIs) and promoters cannot escape the tax net through the buyback route.

3. Corporate Relief: MAT Rate Cut to 14%

Balancing the stricter market taxes, the Finance Minister offered a reprieve to the corporate sector, particularly for companies with high book profits but lower taxable income.

• Rate Reduction: The Minimum Alternate Tax (MAT) rate has been slashed to 14% from the existing 15%.
• Credit Set-Off: A crucial transitional provision allows for MAT credit carry-forward to be set off until March 30.

This reduction effectively lowers the tax floor for companies utilizing exemptions and incentives, aimed at improving cash flows for infrastructure and heavy industry sectors that typically rely on MAT provisions.

4. Customs & Trade: Boosting ‘Make in India’ & Exports

The indirect tax proposals in Budget 2026 focus on two pillars: protecting domestic manufacturing and boosting the competitiveness of export-oriented sectors like seafood.

Removal of Exemptions

To support domestic producers, the government has removed customs duty exemptions on select items that are now manufactured within India. This move is designed to reduce reliance on imports and encourage the sourcing of locally made components.

Boost for Seafood Exporters

Acknowledging the challenges faced by the aquaculture sector, the budget has liberalized import norms for inputs:

• Duty-Free Limit Raised: The limit for duty-free import of inputs used for seafood processing has been hiked to 3% of the value (up from previous limits).
• Impact: This will lower production costs for shrimp and frozen fish exporters, making Indian marine products more competitive in the US and European markets.

Union Budget 2026-27 presents a bold restructuring of financial market taxation. While the hike in STT and the new buyback tax regime may dampen short-term sentiment in the equity markets, the reduction in MAT and strategic customs tweaks signal a long-term commitment to domestic manufacturing and fiscal prudence. Investors and corporates alike will now need to recalibrate their strategies to navigate this new fiscal landscape.
