Singapore enacts 400% tax deduction for AI adoption

The first S$50,000 receives enhanced treatment

New section 14ZK of the Income Tax Act 1947 applies to a person carrying on a trade or business. For each of YA 2027 and YA 2028, the first S$50,000 of qualifying AI expenditure attracts a 300 per cent additional deduction where the expenditure is already deductible under section 14, producing 400 per cent total relief. Where it is not ordinarily deductible under section 14, section 14ZK provides a 400 per cent deduction. Expenditure above the cap retains an ordinary deduction only where the general rules allow it.^[1][2]

Software and implementation services can qualify

Eligible expenditure covers subscriptions or licences for an AI system and subscriptions, acquisitions or licences for qualifying AI business services. Covered services must support development, deployment, operation or maintenance of an AI system and may include online platforms, system development, consultancy, data and analytics, research, engineering, compliance and system-related training. Physical infrastructure and hardware are excluded.^[1][2]

Grants and duplicate claims reduce relief

Government or statutory-board grants are removed from qualifying expenditure. The same amount cannot also receive deductions under specified provisions for intellectual property, research, training or other incentive expenditure. Relief is also denied for an AI system that is sublicensed during the basis period or has already received specified capital allowances. Mixed software or service charges must be apportioned reasonably between qualifying AI and other expenditure, with supporting evidence available for IRAS.^[1][2]

The claim uses existing return routes

Companies claim the enhanced deduction through their income-tax returns. Sole-proprietors and partners submit enhanced-deduction records through the designated IRAS digital service after filing their returns and before the existing filing due date. The AI category cannot be converted into an EIS cash payout. Groups should map Singapore AI subscriptions and implementation contracts by claimant, basis period, grant funding, hardware component and existing deduction or capital-allowance treatment before including relief in YA 2027 forecasts or returns.^[2]

Future exclusions remain possible

The Act is enacted, but it permits future rules to prescribe excluded AI systems, services or expenditure. No such additional prescribed exclusion was identified in the sources reviewed. This focused brief does not complete review of the Act’s separate corporate, international-tax and Pillar Two measures.^[1]
