Singapore Corporate Tax: What SMEs Need to Know in 2025

A practical overview of Singapore's corporate tax system, including the Start-up Tax Exemption scheme, GST registration thresholds, and filing deadlines.

Singapore’s corporate tax rate of 17% is one of the most competitive in Asia. For SMEs and newly incorporated companies, there are additional exemptions that can significantly reduce your effective tax rate.

Start-up Tax Exemption (SUTE)

For the first three years of assessment, qualifying new companies enjoy:

  • 75% exemption on the first S$100,000 of chargeable income
  • 50% exemption on the next S$100,000

This means the effective rate on the first S$200,000 can be as low as 4.25%.

GST Registration

Companies must register for GST once their taxable turnover exceeds S$1 million in a 12-month period. Voluntary registration is also available and may be advantageous depending on your business model.

Key Filing Deadlines

ObligationDeadline
Estimated Chargeable Income (ECI)3 months after financial year end
Corporate Income Tax Return (Form C-S/C)30 November each year
GST ReturnsWithin 1 month after each accounting period
