The AES Tax Update is well known as a detailed update covering not only new tax legislation, regulations, and other guidance, but also recent court cases whose outcomes impact your tax practice. The instructors are experienced CPAs and tax attorneys who consistently receive high marks as seminar leaders. You will be able to download a searchable PDF of the slides that the instructor will use (as well as a printed manual if you attend in person) and additional information. The materials are a valuable reference that you will use often during busy season.
For details on how AES Internet courses work, please see the Internet Courses page. You can type in questions that the instructor will answer during the seminar, but only the instructor is seen or heard online.
The AES Tax Update seminar counts toward continuing education requirements for CPAs, and for enrolled agents and tax return preparers as 1 hour Federal tax ethics and 7 hours Federal tax update. Some states require state-specific ethics content that will not be covered in this course.
