A payroll year consists of 52 weeks for companies that pay their employees weekly, and 53 weeks during leap years. Biweekly payments cover a 26-week period, while monthly payments are spread out over 12 months. Employers are required to make timely payments to their employees in accordance with the Fair Labor Standards Act and state regulations. Therefore, it is essential for companies to be aware of their payroll year and specific payroll period in order to comply with these regulations.
