Which of the following benefits under employer-paid group health plans is usually not received tax-free?

Disability income benefits under employer-paid group health plans are typically not received tax-free because they are often considered taxable income. This means that when an employee receives these benefits due to a disability, they may have to report this income on their tax return and pay taxes on it.

In contrast, benefits such as major medical, vision, and HMO (Health Maintenance Organization) plans usually come with tax advantages for employees. Premiums paid by employers for these types of health insurance are generally not included in the employee's taxable income, making the benefits received under these plans tax-free. Therefore, while health care benefits under employer-paid plans are designed to support employees health-wise without incurring tax burdens, disability income benefits represent an exception to this rule due to their classification as income.
