Imputed income is the taxable value of non-cash employer benefits that must be added to an employee's gross wages for income tax and FICA purposes.
Why imputed income matters for employers
When employers provide non-cash benefits, the value of those benefits is generally taxable unless a specific exclusion applies. When a taxable benefit is provided without cash changing hands, the value is imputed - added to the employee's taxable wages even though no cash was paid.
The most common imputed income items include: group-term life insurance coverage exceeding $50,000 (the cost of the excess coverage is imputed using IRS Table I rates), domestic partner health coverage (if the partner is not a tax dependent), personal use of a company vehicle (calculated using the IRS standard mileage rate or annual lease value method), employer-provided cell phones used for personal purposes (when the personal use can be isolated), and discounts on company products or services that exceed the exclusion limits.
Employers must add imputed income to the employee's W-2 in Box 1 (federal wages), Box 3 (Social Security wages), and Box 5 (Medicare wages). The employee owes income tax and FICA on the imputed amount. Employers also owe the employer share of FICA on imputed income.
Imputed income does not result in additional cash to the employee - they owe taxes on income they never directly received. This often surprises employees when they see their W-2 and is a common source of payroll disputes. Clear communication about imputed income policies reduces confusion.

Frequently asked questions
What is the most common imputed income item?
Group-term life insurance over $50,000 is the most frequently encountered imputed income item. The cost of coverage above $50,000 is calculated using IRS Table I rates and added to taxable wages.
Do employees owe FICA on imputed income?
Yes. Imputed income is subject to both income tax withholding and FICA taxes. The employer also owes the matching employer share of FICA on the imputed amount.
How is domestic partner benefit imputed income calculated?
The fair market value of the health insurance coverage extended to a domestic partner (minus any after-tax employee contribution) is added to taxable wages if the partner is not the employee's tax dependent.
