C Corporations


The Tax Cuts and Jobs Act (TCJA) eliminated graduated tax rates and AMT for C corporations. All corporations are now taxed at a flat 21% beginning January 1, 2018. On the surface, this change may seem like an incentive to use the C corporation structure for conducting a business. However, there are many factors other than tax rates to consider when evaluating whether a business should be organized as a C corporation.

In this self-study course on C-Corporations, you will analyze whether it makes sense for your business clients to maintain their C corporation or to convert to a pass-through entity. Pass-through entities can take advantage of the 20% qualified business income deduction. C corporations cannot. Does it make sense for a new business to form as a C corporation? Should an S corporation revoke its election and convert to a C corporation? What are the consequences of the complete liquidation of a C corporation? How about for an S corporation?

We cover these issues and more in this self-study course.
