Overview of R&D Tax Incentives in Singapore
Singapore offers some of the most generous research and development (R&D) tax incentives in the Asia-Pacific region. Companies that invest in qualifying R&D activities can claim enhanced tax deductions, significantly reducing their effective tax cost. The two principal provisions are Section 14C and Section 14D of the Income Tax Act, supplemented by the Enterprise Innovation Scheme (EIS) introduced in 2023.
Understanding the distinctions between these provisions — and how to structure and document your claims — is essential for any Singapore company undertaking R&D activities.
Section 14C: Approved Research and Development Organisations
Section 14C provides a 150% tax deduction on payments made to approved research and development organisations in Singapore. To qualify:
- The payment must be made to an organisation approved by the Minister for Finance (or a delegated authority) as an approved R&D organisation.
- The R&D must be related to the trade or business of the payer company.
- The payer must not be carrying on the R&D activity itself — the deduction is for outsourced R&D payments.
Approved organisations typically include public research institutions, hospitals conducting medical research, and certain private research bodies. The list of approved organisations is maintained by the Economic Development Board (EDB). Companies should verify that their chosen R&D partner holds the relevant approval before making a claim.
Section 14D: In-House and Contracted R&D
Section 14D provides enhanced deductions for R&D expenditure incurred directly by a company or contracted to a third party in Singapore. The deduction rates are:
- 150% deduction for qualifying R&D expenditure incurred on R&D conducted in Singapore
- 100% deduction for qualifying R&D expenditure incurred on R&D conducted outside Singapore (i.e., the standard deduction, with no enhancement)
Qualifying expenditure under Section 14D includes:
- Staff costs (salaries and related employer contributions) for employees directly engaged in R&D
- Consumables used in the R&D process
- Payments to third-party contractors performing R&D in Singapore on the company’s behalf
Expenditure on plant, machinery, and equipment is not deductible under Section 14D but may be covered by capital allowances or the EIS (see below).
Related trade requirement: The R&D activity must be related to the existing trade or business of the company. A pure investment holding company, for example, would not qualify unless the R&D is in connection with a trade it carries on.
What Qualifies as R&D?
The Income Tax Act defines R&D as activities in the field of science or technology that are:
- Undertaken for the purpose of creating new knowledge, or
- Using new or existing knowledge for making new or improved materials, products, devices, processes, or services
Activities that do not qualify as R&D include:
- Market research, market testing, or sales promotion
- Quality control or routine testing
- Prospecting, exploring, or drilling for minerals, petroleum, or natural gas
- Management studies or efficiency surveys
- Social science or humanities research
The key distinction is whether the activity involves genuine scientific or technological uncertainty and seeks to advance the state of knowledge. Incremental product development that does not resolve technological uncertainty generally does not qualify.
Enterprise Innovation Scheme (EIS)
The Enterprise Innovation Scheme (EIS) was introduced in Budget 2023 and is effective for Years of Assessment 2024 to 2028. It provides a 400% tax deduction (or allowance) on the first S$400,000 of qualifying expenditure per category per year, covering five innovation-related activities:
- R&D conducted in Singapore (qualifying staff costs and consumables)
- Intellectual property (IP) registration costs
- Acquisition of IP rights (capital expenditure on IP)
- Training expenditure under approved courses
- Innovation projects with polytechnics, ITEs, or other qualifying partners
The 400% deduction under EIS is in lieu of (not in addition to) the Section 14C/14D deductions. Companies claim the EIS deduction directly in their corporate tax return.
Cash payout option: Companies that have little or no taxable income — particularly start-ups — may elect to convert up to 20% of qualifying EIS expenditure (capped at S$100,000 of expenditure) into a non-taxable cash payout at a conversion rate of 20 cents per dollar. This provides immediate cash flow benefit for pre-revenue companies.
Interaction Between EIS and Section 14C/14D
For qualifying R&D expenditure in Singapore, the EIS provides the higher deduction rate (400% on first S$400,000) compared to Section 14D (150%). Companies will generally prefer to claim under EIS for R&D expenditure up to the S$400,000 threshold per year, with Section 14D applying to expenditure above that threshold.
Careful planning is required to allocate expenditure optimally between the EIS categories (each with its own S$400,000 cap) and to ensure the qualifying conditions for each are met.
Documentation and Substantiation
IRAS scrutinises R&D claims carefully. Robust documentation is essential and should include:
- Project records: Technical descriptions of each R&D project, the scientific/technological uncertainties being addressed, the approach taken, and results obtained (positive or negative)
- Timesheets: Records of time spent by employees on R&D activities versus other work, to support staff cost apportionment
- Payroll records: Linking individual employees to R&D projects and quantifying salary costs attributable to qualifying activities
- Invoices and contracts: For outsourced R&D, agreements with contractors and invoices supporting payments claimed
- Consumables records: Purchase invoices and usage logs for consumables directly used in R&D
Companies should maintain contemporaneous records — ideally prepared during the course of the R&D, not reconstructed after the fact. IRAS may request these records during a review or audit of the R&D claim.
Claiming the Deduction
R&D deductions under Section 14C, 14D, or the EIS are claimed in the company’s annual income tax return (Form C or Form C-S). There is no separate pre-approval required for Section 14D or EIS claims, though companies must ensure they meet all qualifying conditions. For Section 14C, the third-party recipient must be an approved organisation at the time of payment.
Where the R&D deduction creates a tax loss, the loss may be carried forward to offset future taxable income (subject to the shareholding continuity test) or carried back to the immediately preceding year of assessment (up to S$100,000).
