Essential answers on ACRA registration, Section 145 nominee director rules, small company audit exemptions, and 9% GST requirements.
Under standard conditions, company incorporation via ACRA BizFile+ takes just 1 business day once identity verification (KYC) and paperwork are completed. Delays only occur if the company name contains restricted keywords (such as "Bank", "Finance", or "School") requiring external referral to corresponding Singapore government bodies.
Section 145 mandates that every Singapore-incorporated company must have at least one director ordinarily resident in Singapore (a Singapore Citizen, Permanent Resident, or approved EntrePass/EP holder). Foreign entrepreneurs who do not reside in Singapore can engage OneStop’s certified local nominee director service to remain 100% compliant with ACRA regulations.
Under the 13th Schedule of the Singapore Companies Act, a private company is exempt from statutory external audit if it qualifies as a "small company" by satisfying at least two of the following three criteria in the preceding two financial years: 1. Total annual revenue does not exceed S$10 million; 2. Total assets do not exceed S$10 million; 3. Total full-time employee count does not exceed 50.
GST registration is mandatory under IRAS rules when your company's taxable turnover exceeds S$1 million at the end of any calendar year (retrospective basis) or when you can reasonably forecast that taxable turnover will exceed S$1 million over the next 12 months (prospective basis). The prevailing Singapore GST rate is 9%.
As an official Xero Silver Partner, OneStop connects your business directly to the nationwide Peppol-based InvoiceNow network. We ensure all incoming and outgoing electronic invoices conform with IRAS transmission standards, enabling smooth compliance with statutory mandates for GST-registered businesses.
Qualifying newly incorporated Singapore companies can leverage the Start-Up Tax Exemption (SUTE) scheme for their first three consecutive Years of Assessment. SUTE delivers a 75% exemption on the first S$100,000 of normal chargeable income and a 50% exemption on the next S$100,000, significantly lowering corporate tax liability.
