For a straightforward case, incorporation itself is fast: ACRA states that most registrations are approved soon after payment, often within the hour, once the application is complete.
Allow for the full sequence, though. You must first reserve the company name (S$15, approved name held for 120 days), then file the incorporation. Where the application is more complex ACRA may take up to 15 working days, and if the proposed name or business activity needs clearance from a referral authority – for example a name containing ‘bank’, ‘finance’ or ‘school’ – approval can take 14 to 60 days.
In practice the realistic bottleneck is preparation, not ACRA: gathering identification and address details for all directors, shareholders and beneficial owners, confirming the registered office and SSIC codes, and obtaining consents. Once those are in hand, most incorporations complete the same day.
Opening a corporate bank account is a separate step afterwards and typically takes longer, as banks run their own KYC. Apexia can prepare and file everything for you.
