How it works
A registered business charges GST on taxable supplies, claims input tax on qualifying purchases and files returns for each accounting period. IRAS publishes the current rate, the thresholds and the treatment of exports and international services, which are handled differently from domestic sales.
Commonly mixed up with
Corporate income tax and GST are often merged into one obligation. They are separate regimes with separate registrations, returns and deadlines.
