Level of expertise: No single accounting or tax professional can know everything in the field. Sometimes they need to call in a specialist or tag-team with another professional to perform their duties at the highest level. This is not incompetence; it is professional responsibility. If you have a complex issue, do not feel bad if your accountant needs help on that project. For the record, I often consult other professionals when writing posts for this blog. It is often a reason why I don’t publish more. I like to cover as many bases as possible.
