Singapore deputy prime minister and minister for finance Lawrence Wong’s budget speech in February identified three key thrusts: grow the economy and equip workers with skills; strengthen the social compact and provide better support; and build a more resilient nation.

This article focuses on income tax changes affecting businesses.

Global Anti-Base Erosion (GloBE) rules

Singapore plans to implement GloBE rules under the Base Erosion and Profit Sharing (BEPS) Pillar Two and the Domestic Top-Up Tax (DTT) for larger multinational enterprise (MNE) groups from the financial year starting on or after 1 January 2025. This timeline may be adjusted based on international developments.

If the DTT is introduced, it would top up the effective tax rate of MNEs operating in Singapore with annual group revenue of at least €750m to 15%.

Business income tax changes

Enterprise Innovation Scheme

A suite of tax measures applicable from year of assessment (YA) 2024 to 2028 will be enhanced or introduced to encourage businesses to engage in research and development (R&D), innovation and capability development activities.

Among them is a 400% tax deduction per YA applicable for the first S$400,000 of relevant costs relating to, for example, qualifying R&D, intellectual property rights, and qualifying courses.

Also available is an option to convert into a non-taxable cash payout at a ratio of 20% on up to S$100,000 of total qualifying expenditure per YA, which will only be available to businesses with at least three full-time local employees earning a gross salary of at least S$1,400 in employment for six months or more in the basis period of the relevant YA.

Double Tax Deduction for Internationalisation (DTDi) Scheme

To support businesses in building e-commerce capabilities, the scope of the DTDi Scheme is enhanced to include an e-commerce campaign and to cover expenses paid to e-commerce platform/service providers for business advisory, account creation, content creation, and product listing and placement.

Accelerated Capital Allowance (CA) on Plant and Machinery (P&M)

Businesses will be given an irrevocable option to accelerate the write-off of the cost of acquiring P&M during the financial year ending in 2023 over two years (75% in YA2024 and 25% in YA2025).

Accelerated Deduction for Renovation or Refurbishment (R&R) Expenditure

Businesses will be given an irrevocable option to claim R&R deduction in one YA for qualifying R&R expenditure incurred during the basis period for YA2024, subject to the cap of S$300,000.
