For me, this is the other way around. Four years ago I was having a discussion with couple of other CPAs about how to help a client understand how to change from reporting income to the IRS as a C Corporation to reporting as an S Corporation. This led me to create a worksheet showing the four options for companies to report their business income to the IRS, and benefits and pitfalls of changing.
I later expanded the worksheet with basic tax principles to use for training Staff Accountants on the differences. Then I further expanded the worksheet to show new business owners their options, and advantages and disadvantages of the four options. Next usage - my next Seven Minute Presentation, so our team understands the basics of this important tax concept.
