ESOPs have emerged as a popular way for owners of closely held companies to create a market for their stocks. ESOPs are popular in part due to their significant tax advantages: under certain circumstances the seller is able to defer capital gains taxes on the sale of his stock to an ESOP, or eliminate them entirely if qualified replacement securities are held until death. Subject to applicable regulations, the contributions to ESOPs are tax deductible to the sponsor company as an employee benefit expense. This vehicle also makes it possible to deduct for tax purposes the principal payments on ESOP-related debt incurred by the company.
