Companies in Liquidation: Corppass Access for S45 Filing

The guide shows the chain of authorisation from the company under liquidation to the liquidator’s firm and its staff.

Source checked · 11 October 2026

Register the company administrator

The appointed liquidator or authorised individual registers as the company’s new Corppass administrator. Check existing administrators first; where the maximum two accounts exist, request removal with the appointment order/ACRA notice and identity evidence. Registration requires the company UEN, contact details and scenario-specific authorisation and identity documents. Liquidator appointment alone does not assign every employee digital filing access.

Complete both levels of delegation

The company administrator authorises the liquidator firm as a third party for S45 Withholding Tax (Filing). The firm’s administrator creates staff users and assigns the client’s service, after which staff use myTax Portal Tax Agent Login through Singpass. Verify the represented entity and service before proceeding. This guide establishes portal access, not a filed tax return or proof that withholding has been paid; liquidation does not remove the underlying tax duties.
