Singapore Allowance

Section 19 vs. Section 19A: Balancing Speed and Flexibility

Singapore's Income Tax Act offers two primary routes for capital allowance claims on plant and machinery. Section 19 provides a standard write-off over the asset's prescribed working life — typically three years for computers and software (33.3% per year), five years for office furniture (20%), and ten years for machinery (10%). Section 19A accelerates this to one year (100%) or three years (33.3% per year) for qualifying assets, regardless of expected useful life. A Singapore manufacturing firm purchasing a $500,000 CNC machining center can deduct the entire cost in Year 1 under Section 19A(1), generating approximately $85,000 in tax savings at the current 17% corporate rate — versus $50,000 per year over ten years under Section 19. When interest rates are elevated, accelerating deductions to Year 1 substantially reduces the present-value cost of taxes over the asset's life.

The Enterprise Innovation Scheme and EIS Expansion

Singapore's Enterprise Innovation Scheme (EIS), introduced in Budget 2023 for YA 2024–2028, provides 400% tax deductions on qualifying expenditure up to S$400,000 annually for R&D, IP registration, IP acquisition, employee training, and innovation projects with polytechnics or ITE. Budget 2026 expanded EIS to include qualifying AI expenditures for YA 2027–2028. Businesses can alternatively elect a 20% non-taxable cash payout capped at S$20,000 per YA — useful for companies in tax-loss positions that need immediate cash rather than future deductions. When combined with Section 19A immediate write-off, a qualifying firm can simultaneously maximise capital allowances on hardware while claiming enhanced EIS deductions on software and training costs, compressing the payback period on technology investments substantially.

Capital Allowance Carry-Back and Loss Utilisation

Singapore's one-year carry-back of unabsorbed capital allowances (up to S$100,000 per Year of Assessment) is particularly useful for early-stage companies that invest heavily before generating taxable profits. A tech startup spending S$400,000 on servers and development equipment before its first profitable year can carry back up to S$100,000 to offset taxes paid in the prior year, generating an immediate cash refund. The remaining S$300,000 is carried forward indefinitely against future taxable income, with no time limit — provided there is no substantial change in the company's ownership and business under Section 23 of the Income Tax Act. IRAS defines "substantial change" as a change exceeding 50% in ultimate ownership of shares.
