The wash sale rule is a tax regulation that prevents investors from claiming a tax deduction for a loss on a security if they purchase the same or a substantially identical security within 30 days before or after the sale.
The rule was designed to prevent investors from generating artificial tax losses while maintaining the same investment position.
Investors who sell investments at a loss often want to claim that loss to reduce taxable capital gains. The wash sale rule limits this strategy by disallowing losses if the investor repurchases the same investment within the restricted period.
Understanding the rule helps investors avoid unexpected tax complications.
