Members receive one federal tax research question at no cost each calendar year, plus 50% off the nonmember rate on all subsequent answers. After the first free question, a $33 per answer charge applies for members. Nonmembers are charged $66 per answer.

How We Bill

Billing is per answer, not per call. Follow-up questions are clarifications of the original question and do not include additional facts or require further research/documentation. Follow-up questions will be billed if asked 30 days or more from the original question completion date.

What You Can Expect

If your question is not answered immediately, we will research and provide a response within three to five business days. If extensive research is required, or multiple questions are asked, an additional charge may apply. You will be notified of any additional charges before proceeding.
