Employees younger than 20 years old may be paid less than the federal minimum wage for the first 90 consecutive calendar days of employment. After this time or when the employee turns 21, whichever comes first, the employee is entitled to the full minimum wage rate. If a state or local law requires payment of a higher minimum wage and makes no exception for workers under age 20, the higher rate applies. Note: Youth workers paid less than minimum wage must not displace other workers.
