Semi-weekly pay is a payroll schedule that pays employees twice a week, producing 104 paychecks a year. It is one of the rarest schedules in use — the Bureau of Labor Statistics does not track it as a standard category — and the word “semiweekly” in a payroll context far more often refers to an IRS tax deposit schedule than to how often workers actually get paid.1U.S. Bureau of Labor Statistics.

How a Semi-Weekly Pay Schedule Works
Each work week is split into two pay periods, so a check lands roughly every three or four days. Over a year that adds up to 104 checks.
For a salaried worker, the math is simple: divide the annual salary by 104. Someone earning $52,000 a year would see $500 in gross pay on each check. For an hourly worker, gross pay depends on the hours logged inside that three- or four-day window. Twenty hours at $20 an hour produces a $400 gross check for that half of the week.
It helps to see this against the schedules most workers actually have:
- Weekly: 52 checks a year
- Biweekly: 26 checks a year
- Semimonthly: 24 checks a year
- Monthly: 12 checks a year
- Semi-weekly: 104 checks a year
The Bureau of Labor Statistics classifies private-sector pay periods into four categories: weekly, biweekly, semimonthly, and monthly. Semi-weekly does not appear as a tracked category, which reflects how rarely employers use it.1U.S. Bureau of Labor Statistics. Length of Pay Periods in the Current Employment Statistics Survey Running payroll 104 times a year means calculating withholdings, issuing payments, and keeping records for each cycle, and that administrative load is what keeps most businesses away from it.
Is Semi-Weekly Pay Allowed Under Federal and State Law
Yes. The Fair Labor Standards Act sets rules for minimum wage and overtime but does not require any particular pay frequency. How often you must be paid is left to state law.
Most states require at least biweekly or semimonthly payments, and a handful require weekly pay in certain industries. Because semi-weekly pay involves 104 payments a year, it exceeds the minimum frequency required in every state. Where a state’s rule is stricter than a company’s default, the employer must follow the stricter standard, and states that find employers in violation of their timing rules can impose fines and liquidated damages, with some allowing employees to recover double or triple their unpaid wages. Employers with workers in more than one state need to confirm the schedule meets every applicable requirement.
Semi-Weekly Pay Versus the IRS Semiweekly Deposit Schedule
This is where most confusion around the term comes from. When payroll professionals say “semiweekly,” they are usually not talking about how often employees are paid. They are talking about a federal deposit schedule that controls how quickly an employer must send withheld federal income tax, Social Security tax, and Medicare tax to the IRS.
Under IRS Publication 15, every employer that withholds those taxes follows either a monthly or a semiweekly deposit schedule, and the IRS assigns the schedule based on the total employment taxes reported during a lookback period.2Internal Revenue Service. Publication 15 (Circular E), Employers Tax Guide The deposit schedule has nothing to do with how often the employer pays its workers. A business that runs biweekly payroll can still be a semiweekly depositor if its tax liability is large enough.
So the two uses of the word describe different things:
- Semi-weekly pay is how often the employee gets a paycheck — twice a week, 104 times a year.
- Semiweekly deposits are how often the employer sends withheld payroll taxes to the federal government, on a schedule set by the IRS.
If you were searching for the tax rule, that is a separate topic with its own deadlines, thresholds, and penalties in Publication 15 and Internal Revenue Code Section 6656.
How Overtime Works When a Workweek Is Split Across Two Paychecks
A schedule that pays twice a week almost always cuts a workweek in half. That creates a question workers ask a lot: does overtime get calculated per paycheck, or across the full week?
Across the full week. When a workweek is split between two pay periods, overtime is still calculated based on the full seven-day workweek, not each individual pay period. An employer cannot average hours across two or more weeks to avoid paying overtime.3U.S. Department of Labor Wage and Hour Division. Fact Sheet #23 – Overtime Pay Requirements of the FLSA
Say your workweek runs Sunday through Saturday and your pay periods end on Wednesday and Saturday. Total hours have to be tracked across the full Sunday-to-Saturday week even though those hours will be paid on two separate checks. Any hours above 40 in the workweek must be paid at one-and-a-half times the regular rate, and the overtime pay is normally included in the paycheck for the pay period in which the workweek ends.
Recordkeeping the Employer Owes You
Federal labor law requires employers to keep records of each employee’s daily hours, total weekly hours, wages paid, and pay period dates. Those records form the basis for verifying compliance with minimum wage and overtime rules,4eCFR. 29 CFR Part 516 – Records to Be Kept by Employers and they matter more on a split-week schedule, where the hours on any one paycheck do not tell you whether overtime kicked in.
