It can make sense if most customers are GST-registered or you export, since you recover input tax. Voluntary registrants must remain registered for at least two years and comply with conditions such as GIRO payment and e-learning.
IRAS may backdate the registration, require GST to be accounted for from the date liability arose, and impose a fine of up to S$10,000 and a penalty of 10 percent of the GST due.
IRAS is phasing in a requirement for GST-registered businesses to transmit invoice data via InvoiceNow. It applies to newly incorporated companies that register voluntarily and, from April 2026, to all new voluntary registrants.
