Since some months have 31 days and others have 30, a semimonthly hourly employee may sometimes receive payment for different number of days. For example, the employee may receive payment for 12 days during one pay period and 13 days the next. To allow enough time for payroll processing, the pay period ending date for a semimonthly hourly payroll may be earlier than for a biweekly hourly payroll.
Many states have minimum payday policies, which require an employer to pay employee no less than by the stated time frame. A semimonthly payroll is one of the traditional paydays that may fall into this requirement. Compared to a weekly or biweekly payroll, a semimonthly can be complex.
