How do I add this post-death number to the existing eFiling profile? When two tax numbers of the same type are active with one individual on the same eFiling profile (for example when you activate the post-death together with the pre-death number on the same individual) you can only access the tax returns for one of the tax numbers. When I try to add a new individual with the post-death tax number to the eFiling profile, an error occurs since the individual already exists on the profile (same ID no). How can one add the estate seperately on the eFiling profile? When this was a new feature, a new individual was automatically added on eFiling after the registration process explained in this video. But it no longer does that automatically.
