Final answer:
A wash sale occurs when property is transferred at a price lower than its fair market value.
Step-by-step explanation:
A wash sale refers to a situation where an employer transfers property to an employee or a corporation transfers property to a shareholder at a price lower than the property's fair market value.
For example, if an employer sells a piece of land to an employee for $10,000, even though the fair market value of the land is $15,000, it would be considered a wash sale.
This practice is generally not allowed as it can be used to manipulate the value of transactions and potentially evade taxes.
