How your corporate tax is calculated and what it means
Singapore’s corporate tax rate is a flat 17 percent, but most companies pay less because of available exemptions.
If you are a new company, you may qualify for the Start-Up Tax Exemption (SUTE). If you do not qualify for SUTE, you may still be eligible for the Partial Tax Exemption (PTE). The calculator helps you compare both scenarios and plan more effectively.
Start-Up Tax Exemption (SUTE)
- 75% exemption on the first S$100,000 of chargeable income
- 50% exemption on the next S$100,000
- Full tax on the remaining income
Partial Tax Exemption (PTE)
- 75% exemption on the first S$10,000
- 50% exemption on the next S$190,000
- Full tax on remaining income
These exemptions significantly lower the effective tax rate for most small and medium-sized companies.
