Inland Revenue Authority of Singapore + EnterpriseSG

Administers both Singapore tax and enterprise functions, with grant-like support delivered through enterprise channels.

Inland Revenue Authority of Singapore and Enterprise Singapore are separate statutory boards that together handle the tax and grant sides of Singapore's innovation support. IRAS sits under the Ministry of Finance, while EnterpriseSG sits under the Ministry of Trade and Industry and serves as the main enterprise development agency for SMEs and startups.

Their shared route is the Enterprise Innovation Scheme. It gives 400 percent deductions or allowances on up to S$400,000 of qualifying spend across R&D, IP registration, IP acquisition and licensing, and eligible training, plus a separate innovation-project allowance on up to S$50,000 a year and a cash payout option that can convert up to S$100,000 of spend at 20 percent, or about S$20,000. The scheme runs from YA 2024 through YA 2028, and the same entry also carries the Singapore EDG plus Innovation Tax Allowance route alongside EIS.

EnterpriseSG's wider stack includes the Enterprise Development Grant, Market Readiness Assistance, Productivity Solutions Grant, and Startup SG programs, while IRAS administers the tax deductions and cash payout. That split matters because project approval and tax processing happen in different places. The entry is most relevant to companies working in AI infrastructure, semiconductors, biotech, or medtech that need either SME grant support or innovation tax relief.
