Who it's for
Questions clients ask
Does our company get the start-up tax exemption?
Only if conditions are met, including at least one individual shareholder holding 10% or more. A wholly corporate-owned subsidiary usually gets the partial exemption instead.
When must we register for GST?
When taxable supplies exceed S$1 million in a calendar year, or are expected to in the next 12 months.
Can we pay corporate tax in instalments?
Yes, by GIRO, up to 10 interest-free monthly instalments. Filing ECI early earns more.
Do we need transfer pricing documentation?
When revenue exceeds S$10 million and related party transactions exceed the thresholds. From YA2026 the services threshold is S$2 million.
