Carbon Credit Taxation in India – Section 115BBG, GST, and Compliance Strategies for 2026-27

Introduction: The Tax Dimension of Carbon Trading

Carbon credits are not just environmental assets—they are financial assets. And like all financial assets, they are subject to taxation.

The tax treatment of carbon credits in India is a complex and evolving area. It involves the Income Tax Act, 1961, the Goods and Services Tax (GST) regime, and international tax treaties. For businesses buying, selling, or trading carbon credits, understanding the tax implications is essential for compliance and financial planning.

Two critical issues dominate the tax landscape for carbon credits in India:

1. Section 115BBG: This provision of the Income Tax Act, introduced through the Finance Act, 2022, provides a concessionary tax rate of 10% on income from the transfer of carbon credits. But there is a catch: the concession applies only if the carbon credits are traded on a recognised stock exchange.

2. GST on Carbon Credits: The GST treatment of carbon credits remains uncertain. While some argue that carbon credits should be treated as goods and subject to GST, others contend they are intangible assets or financial instruments that fall outside the GST net.

The budget 2026-27 is likely to bring clarity on these issues, but until then, taxpayers must navigate a landscape of uncertainty.

This guide provides a comprehensive analysis of carbon credit taxation in India, the risks and opportunities, and what businesses must do to ensure compliance.

Section 115BBG: The 10% Tax Regime for Carbon Credits

What Is Section 115BBG?

Section 115BBG of the Income Tax Act, 1961, was introduced through the Finance Act, 2022. It provides a concessionary tax rate of 10% (plus applicable surcharge and cess) on income from the transfer of carbon credits.

The Key Condition

The concession applies only if the carbon credits are traded on a recognised stock exchange. The term "recognised stock exchange" refers to stock exchanges recognised by the Securities and Exchange Board of India (SEBI) under Section 2(f) of the Securities Contracts (Regulation) Act, 1956.

Why This Matters

Aspect	Implication
Tax rate	10% (plus surcharge and cess)
Applicability	Only if traded on a recognised stock exchange
Risk	If not traded on a recognised stock exchange, the income may be taxed at the normal rate of up to 30%

Which Exchanges Qualify?

Currently, carbon credits are expected to be traded on India's power exchanges (IEX, PXIL) rather than traditional stock exchanges. This raises a critical question: do power exchanges qualify as "recognised stock exchanges" for the purposes of Section 115BBG?

The answer is uncertain. While power exchanges are regulated by the Central Electricity Regulatory Commission (CERC), they are not recognised by SEBI under the Securities Contracts (Regulation) Act. This means that carbon credits traded on power exchanges may not qualify for the 10% tax rate.

What This Means for Traders

Scenario	Tax Treatment
Carbon credits traded on SEBI-recognised stock exchange	10% (Section 115BBG)
Carbon credits traded on power exchange or via bilateral agreement	Normal rate (up to 30%)

---

The 30% Tax Risk: When the 10% Regime Does Not Apply

The Risk

If carbon credits are not traded on a SEBI-recognised stock exchange, the income from their transfer will be taxed at the normal rate applicable to the taxpayer:

Taxpayer Type	Tax Rate
Individuals/HUFs	Up to 30% (plus surcharge and cess)
Domestic companies	25-30% (plus surcharge and cess)
Foreign companies	40% (plus surcharge and cess)

The Financial Impact

Transaction Value	Tax at 10%	Tax at 30%	Difference
₹10,00,000	₹1,00,000	₹3,00,000	₹2,00,000
₹50,00,000	₹5,00,000	₹15,00,000	₹10,00,000
₹1,00,00,000	₹10,00,000	₹30,00,000	₹20,00,000

The Technology Penalty

As one analysis notes, "India may face a penalty on technology that it is trying to promote due to old tax rates". The tax uncertainty on carbon credits creates a technology penalty by making carbon trading less attractive and increasing the cost of compliance.

The Concession Dispute

There is also a legal dispute over whether the 10% concession applies to "carbon credits" or "carbon credit certificates" issued under the Energy Conservation Act, 2001. The term "carbon credit" in Section 115BBG may refer to any tradable unit representing emission reductions, regardless of whether it is issued under a specific statute.

---

The Concession Dispute: What "Carbon Credits" Really Means

The Legal Question

Section 115BBG applies to income from the transfer of "carbon credits". But what exactly is a "carbon credit" for tax purposes?

The term "carbon credit" is not defined in the Income Tax Act. However, the Carbon Credit Trading Scheme (CCTS) defines a Carbon Credit Certificate (CCC) as a tradable unit representing one tonne of CO₂ equivalent.

The Argument for the Concession

If a "carbon credit" includes CCCs issued under the CCTS, then income from the transfer of CCCs should qualify for the 10% tax rate (provided they are traded on a recognised stock exchange).

The Argument Against the Concession

If the term "carbon credit" refers only to credits issued under international frameworks such as the Clean Development Mechanism (CDM), then CCCs may not qualify for the concession.

The Practical Impact

Until there is clarity on this issue, taxpayers face significant uncertainty. Those who claim the 10% rate on CCC transactions may face disputes with tax authorities. Those who pay the higher rate may be overpaying tax.

What Taxpayers Must Do

Action	Why It Matters
Seek advance ruling	Get clarity on the tax treatment of CCCs
Maintain documentation	Record all transactions and the basis for tax treatment
Monitor legislative developments	Budget 2026-27 may clarify the issue

GST on Carbon Credits: The Great Uncertainty

The GST Framework

The Goods and Services Tax (GST) is a consumption tax on the supply of goods and services in India. It applies to "goods" and "services" as defined under the GST Act.

The Question

Is a carbon credit a "good" or a "service"? Or is it something else entirely?

Classification	GST Treatment
Goods	Subject to GST (5%, 12%, 18%, or 28%)
Services	Subject to GST (generally 18%)
Intangible asset / Financial instrument	May fall outside the GST net

The Arguments

For GST on Carbon Credits:

• Carbon credits are "goods" as they are tangible, tradable commodities
• The CERC regulations treat CCCs as tradable certificates, which may be considered goods

Against GST on Carbon Credits:

• Carbon credits are intangible assets or financial instruments
• The transfer of intangible assets may not constitute a supply of goods or services

The Practical Impact

Scenario	GST Impact
GST applies	5-28% GST on carbon credit transactions
GST does not apply	No GST on carbon credit transactions

The Need for Clarity

The lack of clarity on GST for carbon credits creates significant uncertainty for businesses. Budget 2026-27 may provide guidance, but until then, taxpayers must navigate this uncertainty.

What Taxpayers Must Do

Action	Why It Matters
Consult with tax advisors	Understand the GST implications of your transactions
Monitor legislative developments	Budget 2026-27 may clarify the issue
Maintain documentation	Record all transactions and the basis for GST treatment

The Technology Penalty: Why Old Tax Rates Affect Carbon Markets

What Is the Technology Penalty?

The "technology penalty" refers to the phenomenon where tax uncertainty and high tax rates discourage investment in clean technologies and carbon trading. As one analysis notes, "India may face a penalty on technology that it is trying to promote due to old tax rates".

How It Affects Carbon Markets

Effect	Impact
Reduced trading activity	High tax rates make carbon trading less attractive
Lower investment	Uncertainty deters investment in carbon projects
Higher costs	Compliance costs are higher due to tax uncertainty
Competitive disadvantage	Indian businesses may face higher costs than international competitors

The Technology Penalty in Action

Sector	Impact
Carbon trading	Higher tax rates reduce trading volumes and liquidity
Carbon project development	Uncertainty deters investment in carbon projects
Clean technology	Reduced investment in clean technology

What Needs to Change

Change	Why It Matters
Clarity on Section 115BBG	Ensure the 10% concession applies to CCCs
Clarity on GST	Provide clear guidance on GST for carbon credits
Reduced tax rates	Lower tax rates for carbon credit transactions

International Tax Treatment: How Other Countries Handle Carbon Credits

The EU ETS

In the European Union, carbon allowances are treated as financial instruments for tax purposes. They are generally exempt from VAT and subject to capital gains tax treatment.

The Australia Model

Australia's carbon pricing mechanism treated carbon units as financial assets. They were exempt from GST and subject to income tax under capital gains provisions.

The California Model

California's cap-and-trade program treats carbon allowances as intangible assets. They are subject to tax on the sale or transfer, but the tax treatment is generally favourable.

The Lesson for India

Lesson	Implication
Treat as financial assets	Carbon credits should be treated as financial instruments
Exempt from GST	Carbon credits should be exempt from GST
Favourable tax treatment	Tax rates should be competitive with international standards
