Singapore has established itself as a pioneer in promoting sustainable development in Southeast Asia. As part of its commitment to reducing carbon emissions and encouraging the adoption of renewable energy, the government has introduced various financial incentives, including tax benefits, grants, and subsidies. This comprehensive guide outlines the key tax advantages and financial support available for green energy investments in Singapore.
Carbon Tax and Its Implications
In 2019, Singapore became the first country in Southeast Asia to implement a carbon tax. This landmark policy has significant implications for businesses and creates strong incentives for renewable energy investments.
Current Carbon Tax Framework
- Current Rate: S$5 per tonne of greenhouse gas emissions (tCO₂e)
- Near-term Increase: S$25 per tCO₂e in 2024-2025
- Medium-term Increase: S$45 per tCO₂e in 2026-2027
- Long-term Target: S$50-80 per tCO₂e by 2030
This progressive increase in carbon tax rates makes investments in renewable energy systems increasingly attractive from a financial perspective. By installing solar panels or wind turbines, businesses can reduce their carbon emissions and consequently lower their carbon tax liability.
Carbon Credit Opportunities
The carbon tax framework also creates opportunities for carbon credit trading:
- Carbon Credit Generation: Renewable energy projects can generate carbon credits by reducing emissions.
- International Trading: Singapore is working on frameworks to enable international trading of carbon credits.
- Potential Revenue Stream: Carbon credits can represent an additional revenue stream for renewable energy project owners.
Tax Incentives for Renewable Energy Investments
Singapore offers several tax incentives specifically designed to encourage investments in renewable energy systems and energy-efficient technologies.
1. Enhanced Capital Allowance (ECA) Scheme
The ECA scheme allows businesses to accelerate depreciation for qualifying energy-efficient or renewable energy equipment:
- Allowance Rate: 100% write-off of the capital expenditure in the first year
- Eligible Equipment: Solar PV systems, energy storage systems, energy-efficient chiller systems, and other approved green technologies
- Benefits: Reduces taxable income in the year of purchase, improving cash flow and return on investment
For example, a company investing S$100,000 in a solar PV system can deduct the entire amount from its taxable income in the first year, potentially saving up to S$17,000 in corporate taxes (at the 17% corporate tax rate).
2. Investment Allowance (IA) Scheme
The IA scheme provides an additional tax deduction on top of the normal capital allowance:
- Allowance Rate: Up to 50% of the approved capital expenditure
- Eligible Projects: Energy efficiency projects, renewable energy systems, and water conservation projects
- Application: Must be approved by the Economic Development Board (EDB)
This means that for a S$100,000 investment in renewable energy equipment, a company could potentially claim deductions totaling S$150,000 (100% standard depreciation plus 50% investment allowance).
3. Green and Sustainability-Linked Loan Scheme (GSLS)
While not a direct tax benefit, the GSLS offers preferential interest rates for loans used to finance green projects:
- Interest Subsidy: Up to 3% reduction in interest rates
- Loan Coverage: Up to 70% of project cost
- Maximum Loan: Up to S$20 million
The interest paid on these loans is generally tax-deductible, further enhancing the financial benefits of renewable energy investments.
Grants and Subsidies for Renewable Energy Projects
In addition to tax incentives, Singapore offers various grants and subsidies to support renewable energy adoption.
1. Energy Efficiency Fund (E2F)
The E2F provides financial support for energy efficiency projects and renewable energy systems:
- Funding Amount: Up to 50% of qualifying costs
- Cap: Up to S$2 million per project
- Eligible Projects: Energy-efficient equipment upgrades, renewable energy systems, energy management information systems
While grants themselves are not taxable income, they reduce the capital cost basis for tax depreciation purposes.
2. Productivity Solutions Grant (PSG)
The PSG supports businesses in adopting energy-efficient technologies:
- Funding Amount: Up to 70% of qualifying costs
- Cap: Varies by solution, typically up to S$30,000
- Eligible Solutions: Pre-approved energy-efficient equipment and renewable energy technologies
3. Resource Efficiency Grant for Energy (REG(E))
Specifically designed for manufacturing facilities to improve energy efficiency:
- Funding Amount: Up to 50% of qualifying costs
- Cap: Up to S$3 million per project
- Eligible Projects: Energy efficient equipment, adoption of renewable energy, waste heat recovery systems
Special Considerations for Different Sectors
Commercial Building Sector
Commercial buildings can benefit from the Building Retrofit Energy Efficiency Financing (BREEF) Scheme:
- Loan Guarantee: Government provides partial risk-sharing with financial institutions
- Eligible Projects: Energy efficiency retrofits, renewable energy systems
- Additional Benefit: Green Mark certification can lead to higher property values and rental premiums
Industrial Sector
Industrial facilities have access to specialized incentives:
- Energy Efficiency Improvement Assistance Scheme (EASe): Co-funding for energy assessments and efficiency improvements
- JTC Solar Land Program: Leasing of rooftop space for solar PV installations with revenue-sharing arrangements
Residential Sector
For homeowners and residential property developers:
- HDB Green Towns Program: Installation of solar panels on public housing blocks
- Enhanced Central Intermediary Scheme (ECIS): Allows homeowners with solar panels to sell excess electricity back to the grid
Application Process and Eligibility
To access these tax benefits and incentives, businesses typically need to follow these steps:
- Pre-qualification: Ensure your business and project meet the basic eligibility criteria
- Energy Assessment: Conduct an energy audit or feasibility study to identify potential improvements
- Application Submission: Submit applications to the relevant government agencies (e.g., NEA, EDB, or BCA)
- Implementation: Execute the project according to approved specifications
- Verification: Undergo verification of energy savings or renewable energy generation
- Tax Filing: Claim the relevant tax incentives in your company's tax returns
Key Eligibility Criteria
- Registered business entity in Singapore

Case Study: Financial Benefits of Solar PV Installation
To illustrate the combined impact of these incentives, consider a medium-sized commercial building installing a 100 kWp solar PV system:
Project Parameters:
- Installation Cost: S$200,000
- Annual Energy Generation: 130,000 kWh
- Electricity Tariff Savings: S$32,500 per year (at S$0.25/kWh)
- Carbon Tax Savings: S$260 per year (at S$5/tCO₂e, increasing over time)
Financial Benefits:
- Grant Support: S$60,000 (30% of cost through E2F)
- Net Investment: S$140,000
- First-Year Tax Deduction: S$140,000 (100% ECA) + S$70,000 (50% IA) = S$210,000
- Tax Savings: S$35,700 (at 17% corporate tax rate)
- Simple Payback Period: 2.4 years (considering tax benefits)
- IRR over 25 years: 24.5%
This example demonstrates how the combination of grants, tax incentives, and ongoing operational savings can make renewable energy investments highly attractive from a financial standpoint.
