While most Singapore companies are familiar with Section 19A capital allowances on plant and machinery, fewer know about its powerful cousin — Section 19B of the Income Tax Act 1947, the Investment Allowance scheme. Section 19B grants approved companies a tax deduction of 30% to 100% of qualifying fixed capital expenditure on top of the normal capital allowances. For a manufacturer or technology firm investing S$10 million in new equipment, the additional deduction can shelter the next several years of profit from corporate tax.
This article explains how Section 19B works in 2026, what counts as “approved qualifying activity”, how to apply through the Economic Development Board (EDB), the documentary requirements, and how Section 19B interacts with the Pioneer Certificate, the Enterprise Innovation Scheme, and the 15% global minimum tax under BEPS Pillar Two.
What Is the Investment Allowance?
Section 19B allows a company carrying on an “approved project” to claim, in addition to the normal capital allowances under Section 19A, an investment allowance computed as a specified percentage (between 30% and 100%) of the company’s “fixed capital expenditure” incurred on the project during the qualifying period.
The mechanics:
- Approved project: the company applies to the EDB and receives a Section 19B certificate specifying the project, the qualifying period (usually 3-5 years), the IA percentage, and any conditions.
- Fixed capital expenditure: capital expenditure on productive equipment, plant, and machinery directly used in the approved project. Land, buildings (except certain manufacturing buildings under section 18C), and working capital are excluded.
- Investment allowance: computed as (Approved %) × (Qualifying Fixed Capital Expenditure). This is deductible against the company’s taxable income on top of the Section 19A allowance.
- Unutilised IA: carries forward indefinitely subject to the section 23 shareholding continuity test, similar to capital allowances.
Example: A precision engineering company receives a 50% IA on a S$10 million approved project. It claims:
- Section 19A: S$10m × 100% (1-year write-off) = S$10m allowance.
- Section 19B: S$10m × 50% IA = S$5m additional allowance.
- Total tax deduction: S$15m against profits, equating to S$2.55m of corporate tax saved at 17%.
What Qualifies as an Approved Project?
EDB has discretion over what qualifies. In practice, projects approved for Section 19B typically fall into these categories:
- Manufacturing expansion — building or expanding production capacity in Singapore for high-value goods.
- Mechanisation and automation — replacing labour-intensive processes with automated lines.
- R&D infrastructure — capital equipment for in-house research labs.
- Technology adoption — equipment for AI, robotics, additive manufacturing, advanced semiconductor processes.
- Service activities of strategic value — back-office automation, data centres, financial technology infrastructure (subject to EDB sector focus).
- Sustainability and decarbonisation — equipment for emissions reduction, clean energy, and circular economy initiatives (a growing priority under Singapore’s Green Plan 2030).
The common thread is that the project must create economic value-add in Singapore — jobs, capability, exports, or strategic capacity.
How to Apply for Section 19B
Step 1 — Engage EDB early
The IA must be applied for and approved before the company commits to the capital expenditure. Retrospective approval is generally not granted. Engage EDB at the feasibility stage of the project — typically 6 to 12 months before the planned capex date.
Step 2 — Submit a project proposal
The proposal should set out:
- The nature and scale of the project (capital cost, location in Singapore, technology, headcount).
- The qualifying activity (manufacturing, R&D, services).
- Economic spillover (jobs created, training, exports, value chain depth).
- The capex schedule (annual budget over the qualifying period).
- Why Singapore was chosen over alternative locations.
Step 3 — Negotiate the IA percentage and conditions
EDB negotiates the IA percentage (30% to 100%), the qualifying period, and any economic commitments — typically headcount, R&D spend, or value-added thresholds.
Step 4 — Receive the Section 19B certificate
The certificate is signed by the Minister for Trade and Industry (or his delegate). It specifies the approved project, the capex categories, the IA percentage, and the conditions.
Step 5 — Claim IA in the corporate tax return
The company files the IA claim in its Form C for each year of assessment. Supporting documents (invoices, fixed asset register, EDB certificate) must be retained for IRAS audit.
Interaction with Other Incentives
- Pioneer Certificate / Development & Expansion Incentive: A company can hold both. Pioneer status gives a concessionary tax rate on qualifying income; Section 19B accelerates deductions on the capex used to generate that income.
- Enterprise Innovation Scheme (EIS): Section 19B and the EIS can apply to different categories of expenditure. EIS targets R&D, IP registration, and training; Section 19B targets fixed capital expenditure on equipment.
- Section 14U pre-trade expenses: For projects in pre-commencement phase, pre-trade expense rules under Section 14U interact with the IA timing — the IA arises only when the asset is brought into use.
- BEPS Pillar Two / GloBE rules: For multinational groups with consolidated revenue above EUR 750 million, the 15% global minimum top-up tax applies from 2025. The IA reduces accounting tax but may trigger a top-up if Singapore ETR falls below 15%. EDB and IRAS have signalled that the IA’s substance-based exception provisions will be carefully applied to preserve its effectiveness for genuinely high-value projects.
Common Mistakes
- Applying after committing to the capex. The IA cannot be back-dated. Engage EDB before any binding purchase order.
- Claiming on non-qualifying assets. Land and buildings (other than certain manufacturing buildings) are excluded. Software and IP are usually not within the 19B basket — those go via Section 19A intangibles or the EIS.
- Failing to maintain the fixed asset register. IRAS audits require asset-level traceability between the invoice, the EDB certificate, and the IA claim.
- Breaching the IA conditions. Disposing of the asset early, or relocating production out of Singapore, can trigger clawback of the IA. The IRAS treatment of clawback is harsh — typically a balancing charge equal to the IA claimed.
- Ignoring the BEPS Pillar Two interaction. Multinational groups must model the Pillar Two effect before relying on the IA in deal pricing.
Who Should Consider Section 19B?
- Manufacturers planning a S$5m+ capex programme in Singapore over the next 3-5 years.
- Technology firms with capital-intensive R&D or pilot lines (semiconductor, biotech, advanced materials).
- Service companies with significant infrastructure investment (data centres, fintech platforms, logistics hubs).
- Companies undergoing automation transformation with material plant and machinery spend.
- Companies aligning capex with Singapore’s Green Plan 2030 priorities (carbon capture, energy efficiency, circular economy).
