at-risk rule(redirected from At Risk Rules)
In tax law, a rule disallowing investors from deducting more investment money from their taxable income than they have actually invested. For example, if one places $10,000 in a stock and would otherwise derive $15,000 in tax deductions from the investment, the at-risk rule only allows the investor to deduct $10,000. The rule exists to prevent a person from investing in a way that avoids taxes excessively.
A law that limits tax write-offs to the amount of money directly invested (and thus, at risk) in an asset. The purpose of an at-risk rule is to prohibit investors from deriving tax benefits that exceed the amount of money actually invested.
