If your company is considering factory solar, commercial rooftop solar, warehouse solar, shopping mall solar, office solar or industrial solar system installation, you may have heard the phrase “100% GITA tax allowance”.
However, under Malaysia’s 2026 solar and green technology incentive framework, companies must first identify whether their solar project is mainly an own-consumption solar system or a renewable energy generation project for business purpose. This classification may affect the application authority, tax incentive percentage, document requirements and compliance process.
This Solar100 guide explains the key differences between GITA Asset, GITA Project, MGTC, MIDA, MyHIJAU, Solar ATAP, SuRIA Home and corporate solar ROI so businesses can make a safer decision before installing solar.
Important note: This article is a corporate solar policy and business decision guide. It is not formal tax advice. GITA, Solar ATAP, SuRIA Home and corporate income tax treatment should always be confirmed with the latest guidance from MIDA, MGTC, SEDA, TNB, LHDN and a registered tax agent.
Many businesses searching for “GITA solar Malaysia”, “solar tax incentive Malaysia” or “corporate solar tax allowance” may see the phrase “100% Green Investment Tax Allowance”. This does not mean every company installing rooftop solar panels automatically qualifies for a 100% capital expenditure tax allowance.
In practice, companies should first separate their solar project into two broad routes:
| Project Type | Common Situation | Application Direction | Common Tax Treatment |
|---|---|---|---|
| GITA Asset for Own Consumption | A company installs solar on its own factory, warehouse, office or commercial building mainly to reduce its own TNB electricity bill. | Usually handled under the MGTC route. | Renewable Energy System is commonly treated as Tier 2, with 60% GITA and up to 70% statutory income set-off. |
| GITA Project for Business Purpose | A company undertakes renewable energy generation as a business activity, such as a solar power generation project. | Usually handled under the MIDA route. | Solar renewable energy generation may qualify for 100% GITA, up to 70% statutory income set-off and a 5-year incentive period. |
The practical SEO takeaway is this: corporate solar GITA may be 60% or 100%, depending on the nature of the project. A normal factory installing rooftop solar for its own electricity consumption should not automatically assume it qualifies for 100% GITA.
GITA stands for Green Investment Tax Allowance. It is not a direct cash rebate or grant. Instead, it allows qualifying green technology capital expenditure to be used as a tax allowance against statutory income, subject to the relevant rules and approval.
For high-electricity businesses such as factories, warehouses, commercial buildings, cold storage facilities, manufacturing plants, logistics centres and large offices, GITA may be important because it can support the overall financial case for solar installation.
It may reduce the post-investment tax burden: Qualifying capital expenditure may receive tax allowance treatment, improving the overall investment structure.
It may improve solar ROI: Solar reduces TNB electricity bills, while GITA may help optimise the tax-adjusted payback period.
It supports ESG and supply chain competitiveness: For export manufacturers, multinational suppliers, electronics companies, food processors and larger commercial groups, solar can help reduce carbon emissions and strengthen the company’s green positioning.
It works alongside Solar ATAP planning: From 2026, Solar ATAP is one of the key rooftop solar frameworks in Peninsular Malaysia. Businesses may need to optimise self-consumption and eligible surplus export together.
If your company mainly wants to reduce its own TNB bill by installing a solar PV system on a factory, warehouse, office, school, hotel, retail property or commercial building, the project may be closer to the GITA Asset for Own Consumption route.
Common users: Manufacturers, warehouses, logistics centres, commercial buildings, schools, hotels, cold rooms, offices, retail premises and other high-electricity commercial users.
Common points for own-consumption solar:
Main purpose: Reducing the company’s own TNB electricity bill, not generating electricity as the company’s main source of income.
Application authority: New own-consumption applications should usually refer to the MGTC GITA Asset route.
Tax treatment: Renewable Energy System for own consumption is commonly treated under 60% GITA, with up to 70% statutory income set-off.
Qualifying capital expenditure period: The qualifying capital expenditure must fall within the period stated in the current guideline.
Asset requirement: Relevant green technology assets should comply with MGTC, MyHIJAU or other government-recognised listing requirements and be used by the company in Malaysia.
If the solar project is not simply for self-use, but is part of a renewable energy generation business, the company may need to refer to GITA Project for Business Purpose.
This type of project usually requires careful review of:
Application authority: The MIDA route is usually relevant for GITA Project for Business Purpose.
Application timing: Companies generally need to submit the tax incentive application to MIDA before incurring qualifying CAPEX for the proposed project, subject to the relevant guideline.
Tax treatment: Solar renewable energy generation may qualify for 100% GITA, up to 70% statutory income set-off and a 5-year incentive period.
Project approval: Relevant project approvals, equipment verification, company documents and compliance confirmation may be required.
Do not mix the two routes: A normal factory installing rooftop solar on its own roof to reduce its electricity bill is not automatically the same as a renewable energy generation business project. The project classification should be confirmed with the company’s tax agent, solar EPC and the relevant authority.
One of the most common questions from businesses is: “If my company installs an RM500,000 or RM1,000,000 solar system, can I claim 60% or 100%?” The answer is not based only on project cost. It depends mainly on the project nature.
| Comparison Item | 60% GITA | 100% GITA |
|---|---|---|
| Common Route | GITA Asset for Own Consumption | GITA Project for Business Purpose |
| Common Solar Use | Company self-consumption to reduce its own TNB electricity bill | Renewable energy generation business project |
| Common Authority | MGTC | MIDA |
| Statutory Income Set-Off Limit | Usually 70% | For solar generation, usually 70% |
| How to Judge | Check whether the solar system is used for own consumption | Check whether the project is a renewable energy generation business activity |
The following is a simplified illustration for understanding only. It is not a formal tax computation.
Example: A factory installs an RM500,000 solar system for own consumption
If the project falls under GITA Asset for Own Consumption and qualifies for 60% GITA, the possible GITA allowance may be illustrated as RM500,000 × 60% = RM300,000.
The amount that can be set off each year is still subject to the 70% statutory income limit and the company’s actual tax position.
If the allowance cannot be fully used in the same year, the unutilised allowance may be carried forward until fully absorbed, subject to confirmation by the company’s tax agent.
The actual tax benefit is not the same as a direct discount on the solar installation price. Businesses should assess taxable income, statutory income, capital allowance, other incentives, financing cost and LHDN treatment together.
Solar ATAP is one of the main rooftop solar mechanisms in Peninsular Malaysia from 2026. It allows eligible consumers to install rooftop solar mainly for self-consumption and export qualifying surplus electricity to the grid for bill credit treatment.
Key Solar ATAP points for companies:
Non-domestic users: Solar capacity may be designed based on Maximum Demand, up to 100% of Maximum Demand, subject to technical assessment, connection requirements and the maximum programme limit.
Self-consumption remains important: The system should not simply be maximised based on roof size. It should be designed around daytime load, operating hours and the company’s load profile.
Excess export is not always the best ROI driver: If the company has insufficient daytime consumption, excessive export may reduce overall project return.
RPVSP support is required: Companies usually need to appoint a SEDA Registered PV Service Provider to assist with the Solar ATAP application submission.
No. GITA is a tax incentive, while Solar ATAP is a rooftop solar electricity mechanism.
| Item | GITA | Solar ATAP |
|---|---|---|
| Nature | Tax incentive | Rooftop solar electricity framework |
| Main Authority | MGTC or MIDA, depending on the project type | SEDA / TNB / relevant electricity authority |
| Business Focus | CAPEX, tax allowance, statutory income and LHDN claim | System capacity, self-consumption, grid export, bill credit and technical assessment |
| ROI Impact | May improve after-tax investment return | Affects electricity savings and system sizing |
If your company has a high monthly TNB bill and suitable rooftop space, solar may be worth including in financial and ESG planning.
Manufacturing factories: Electronics, electrical, plastic, metal processing, food processing, packaging, furniture and machinery manufacturing.
Warehouses and logistics centres: Large roof areas may be useful, but the daytime electricity load must still be assessed.
Commercial buildings: Offices, malls, hotels, schools, universities, hospitals, cold rooms and retail centres.
Export and supply chain companies: If customers or group headquarters care about ESG, carbon emissions and green procurement, solar may become part of the company’s competitiveness.
Companies with stable taxable income: The actual value of GITA is often linked to profitability and statutory income.
Selangor and Klang Valley:
Factories, warehouses and commercial buildings in Shah Alam, Klang, Port Klang, Subang Jaya, Petaling Jaya, Puchong, Rawang, Semenyih, Kajang, Balakong, Cyberjaya and Sepang often search for factory solar Selangor, commercial solar Klang Valley, GITA solar Selangor and Solar ATAP installer Selangor.

Industrial users in Johor Bahru, Pasir Gudang, Senai, Kulai, Iskandar Puteri, Tebrau, Pengerang and Tanjung Langsat may compare industrial solar Johor, factory solar Pasir Gudang, commercial solar Senai and GITA solar Johor.
Penang and Kedah:
Manufacturers in Bayan Lepas, Batu Kawan, Perai, Bukit Minyak, Kulim Hi-Tech Park and Sungai Petani may compare factory solar Penang, industrial solar Batu Kawan, solar GITA Penang and renewable energy Kedah.
Melaka, Negeri Sembilan and Perak:
Factories and commercial users in Ayer Keroh, Batu Berendam, Nilai, Seremban, Ipoh, Chemor and Taiping may also assess commercial rooftop solar, Solar ATAP and GITA tax benefits.
The exact document requirements may differ depending on the project and application route. Before committing to a commercial solar installation, businesses should prepare the following information:
Company information: SSM documents, company registration details, shareholding structure, directors’ information and business activities.
Financial information: Latest audited financial statements, tax computation and estimated taxable income.
Electricity information: At least 12 months of TNB bills, Maximum Demand, tariff category, peak/off-peak usage and load profile.
Project information: Solar system size, equipment list, quotation, roof plan, layout, structural assessment and estimated generation.
Equipment compliance: Confirmation that solar panels, inverters, BESS or related assets comply with MyHIJAU, MGTC or other government-recognised list requirements.
Application route: Confirm whether the project falls under GITA Asset for Own Consumption or GITA Project for Business Purpose.
1. Is this project classified as GITA Asset or GITA Project?
The answer may affect the MGTC/MIDA route, GITA percentage and application timing.
2. Do the quoted components comply with MyHIJAU or MGTC requirements?
Do not check only the brand name. Confirm the full model and compliance documents.
3. How is the Solar ATAP capacity calculated?
The design should be based on Maximum Demand, daytime load and roof capacity, not just the largest possible roof layout.
4. How is the estimated saving broken down?
Separate direct self-consumption savings, exported electricity credit, tax allowance and financing cost.
5. Who handles the applications and documents?
Solar ATAP, GITA, structural assessment, ST licensing, TNB meter procedures and technical assessment responsibilities should be clearly stated.
6. What happens if GITA is not approved?
The quotation or contract should clarify whether the company will still proceed and how the ROI changes without the tax incentive.
Many businesses only look at the solar system price. A more professional approach is to include electricity savings, tax effect, financing cost and ongoing maintenance.
Corporate solar ROI should include:
Total system price, including solar panels, inverter, mounting, cable, protection equipment, engineering and application fees.
Expected monthly TNB electricity savings.
Direct self-consumption and exported energy credit under Solar ATAP.
Potential tax impact from GITA allowance.
Differences between loan, PPA, leasing and cash purchase.
O&M, insurance, inverter replacement and system performance risks.
If the company has stable daytime electricity consumption, a high TNB bill, usable rooftop space and sufficient statutory income, solar combined with GITA may offer a more attractive after-tax return.
Mistake 1: Assuming all corporate solar projects qualify for 100% GITA.
Own-consumption renewable energy systems usually need to be reviewed under the 60% GITA Asset route.
Mistake 2: Assuming installer claims guarantee approval.
GITA still depends on project type, documentation, equipment compliance, application timing and authority approval.
Mistake 3: Treating GITA as a cash rebate.
GITA is a tax allowance, not a direct cash payment from the government.
Mistake 4: Oversizing the system.
Solar ATAP and corporate ROI should be based on daytime self-consumption, Maximum Demand, roof condition and tariff structure.
Mistake 5: Installing first and checking documents later.
Different GITA routes have different timing requirements. Businesses should confirm the route before signing and before incurring CAPEX where required.
If your company is already considering a solar PV system, 2026 is an important year to evaluate the project seriously. Key reasons include the GITA application window, Solar ATAP framework, TNB electricity cost management, ESG requirements and green supply chain pressure.
However, “evaluate early” does not mean “sign immediately”. Companies should complete three checks first:
Check the electricity bill: Confirm monthly TNB bill, Maximum Demand, usage time and tariff category.
Check the roof: Confirm roof area, structure, waterproofing condition, shading and available installation capacity.
Check the tax position: Ask a tax agent to assess whether the company has enough statutory income to absorb the GITA allowance.
