Understanding what is gtl imputed income can help employees make sense of certain amounts appearing on their pay statements. GTL, or Group Term Life insurance, may create taxable imputed income when employer-provided coverage exceeds the applicable IRS threshold. The imputed amount represents the taxable value of that additional coverage rather than extra cash paid directly to the employee. It can therefore increase taxable wages and affect the amount of taxes withheld from a paycheck. Employees reviewing their benefits and payroll deductions may find this information useful when checking compensation details.
