Mamont248 [21]

Answer:

a. Steve will not have a capital gain in Year 1 for tax purposes.

Explanation:

Since Steve (the owner of Barb) sold his stocks to an ESOP (employee stock ownership plan), then he will be able to avoid capital gains taxes at least for the first year. ESOPs are qualified retirement plans and when they invest in stocks of the same sponsoring company, the transaction is not taxed if the seller reinvests (buys other stocks). As long as ESOP holds at least 30% of the company's stocks, then Steve can defer his taxes.
