Key Tax Deadlines for Singapore Businesses

Singapore businesses need to be aware of the following important tax filing deadlines set by IRAS:

• 31 March – Filing deadline for Estimated Chargeable Income (ECI) for companies with a financial year ending in December.

• 15 April – Paper filing deadline for corporate income tax returns.

• 30 November – E-filing deadline for Form C-S / Form C-S (Lite) / Form C for corporate income tax.

• 31 December – Annual GST return submission deadline for companies on yearly filing cycles.

Failing to comply with these deadlines may result in fines, interest charges, and compliance issues with ACRA and IRAS.

Tax Planning Strategies to Optimize Savings

Maximize Tax Deductions and ReliefsSingapore offers various tax incentives, including the Start-Up Tax Exemption (SUTE) Scheme for new businesses and the Partial Tax Exemption (PTE) Scheme for established firms. Businesses should also claim allowable business expenses, including rental, wages, and CPF contributions.

Staying updated on schemes such as the Corporate Income Tax Rebate and Double Tax Deduction for Internationalisation (DTDi) can lead to significant tax savings.
