If the sole-proprietor or the partnership is GST registered, the business owner also has to apply for cancellation of GST registration with IRAS. Find out more at IRAS website.
A sole-proprietor or partner may notify ACRA it has ceased business by filing the "File cessation or dissolution of business entity" eService online via Bizfile.
Business owners or authorised representatives must ensure that they enter the correct information when using this eService, as the business will be deemed ceased immediately upon submission of the application.
