Question – An S corporation is only subject to the built-in gains tax if it was previously a C corp, correct? This question does not really make it clear that it was a C corp changing to an S corp:
Commerce Corp. elects S corporation status as of the beginning of the current year. At the time of Commerce's election, it held a machine with a basis of $20,000 and a fair market value of $30,000. In March of the current year, Commerce sells the machine for $35,000. What would be the amount subject to the built-in gains tax?
a. $15,000
b. $0
c. $5,000
d. $10,000
Explanation
Choice “d” is correct. The built-in gain for the machine is $10,000, the difference, on the date of the election of S status, between the $20,000 adjusted basis of the machine to the C corporation and the $30,000 fair market value. That is the amount of the gain that occurred while the corporation was a C corporation, and it is also the amount that is subject to the built-in gains tax.
