CPAs normally base their fees on the time required to perform the services you request.
There are no “fee schedules” common to the profession. Fees depend on the type of services you require, the prevailing cost in the community, the CPAs level of expertise, and the complexity of your work.
Talk frankly with you CPA about fees. Find out how much you will pay to have work performed by a staff accountant who is under the supervision of a CPA, a higher-level employee such as a supervisor, or perhaps even a partner of the firm.
