eRegistration for Companies
When registering a new company for tax using the eRegistration service it will be necessary to enter the Companies Registration Office (CRO) number. This requirement applies from 7 December.
The CRO number will be verified and will be used to pre-populate the fields on the “Company Details” screen in the eRegistration service.
There will be other new fields dealing with the type of company and company director.
Further details are set out in Revenue eBrief No. 111/15 which you can read here.
