Weekly payroll
Employees are paid once each week. This can align naturally with weekly timekeeping and can make overtime review intuitive when the employer’s workweek lines up closely with the pay cycle. The tradeoff is more payroll runs and more frequent administrative deadlines.
Biweekly payroll
Employees are generally paid every two weeks, producing about 26 pay periods in a normal year. Two months usually contain a third pay date. For salaried employees, that calendar effect can matter when budgeting benefits, deductions, and annual salary allocations.
Semimonthly payroll
Employees are paid twice per month, often on fixed calendar dates, for 24 pay periods. The periods do not always align cleanly with workweeks. For nonexempt employees, overtime still has to be measured under the applicable workweek rules rather than by simply looking at the semimonthly period total.
Monthly payroll
Monthly payroll produces 12 pay periods and the least frequent processing schedule, but it can create longer gaps between employee paydays. State law may restrict when monthly payroll is allowed or which employees can be paid on that schedule.
How to compare schedules
| Schedule | Typical pay periods/year | Operational tradeoff |
|---|---|---|
| Weekly | 52 | Frequent processing; close to weekly time records |
| Biweekly | 26 | Common employee rhythm; occasional three-paycheck months |
| Semimonthly | 24 | Fixed monthly dates; workweeks can cross period boundaries |
| Monthly | 12 | Lowest run frequency; longest gap between paydays |
State law comes first
There is no one payroll frequency that works everywhere. States can regulate how often employees must be paid and can apply different rules by occupation or employee type. Check the current law for every state in which employees work before choosing or changing a pay schedule.
Do not confuse pay frequency with federal deposit frequency
IRS “monthly” and “semiweekly” deposit schedules describe when an employer deposits certain federal employment taxes. They do not describe how often employees are paid. A business can pay employees biweekly and still be a monthly or semiweekly federal tax depositor under the IRS rules.
Quick FAQ
Is biweekly the same as semimonthly?
No. Biweekly means every two weeks; semimonthly means twice per month. That creates about 26 versus 24 pay periods per year.
Which schedule is easiest for overtime?
A schedule that makes weekly timekeeping easy can reduce administrative friction, but overtime is determined by the applicable workweek rules regardless of pay frequency.
Can I change pay frequency whenever I want?
Not without checking state law, employee notices, contracts, benefit deductions, and operational consequences. Treat a frequency change as a payroll policy change, not merely a calendar edit.
