A payroll cycle is the recurring schedule a business uses to calculate wages and pay its workers. Most employers pick one of four standard frequencies — weekly, biweekly, semimonthly, or monthly — and that choice ripples through overtime calculations, tax deposit deadlines, and cash flow for both the company and its employees. Federal law only requires that pay arrive on a consistent, regular schedule. State law is usually where the real constraints sit.
The Four Standard Frequencies
Weekly payroll runs every seven days and produces 52 pay periods a year. It is common in construction, hospitality, and other hourly-heavy industries. The tradeoff is cost: every run takes time, and if you use a payroll service, every run triggers a fee. A provider charging $3 per employee per run costs roughly $12 per employee per month on a weekly schedule versus $6 on a biweekly one.
Biweekly payroll runs every two weeks, creating 26 pay periods a year. Because the calendar doesn’t divide evenly into two-week blocks, two months each year contain three paydays instead of two. Which months depends on when the first pay date falls. In 2026, an employer with a January 2 start date would see three-paycheck months in January and July, while a January 9 start would push those months to May and October.
Semimonthly payroll pays twice a month on fixed calendar dates, such as the 1st and the 15th. That always produces exactly 24 pay periods regardless of how the calendar falls. Benefit deduction math is cleaner because each check covers half a month, but overtime for hourly workers gets awkward because pay periods don’t align with full workweeks.
Monthly payroll means one payment per month, or 12 pay periods a year. Businesses often reserve this for salaried executives or professional staff. It carries the lightest administrative burden but can strain employees living paycheck to paycheck, and many states don’t allow it for hourly workers.
Workweek vs. Pay Period
Every payroll cycle sits on top of a defined workweek, and the two are not the same thing. Under federal law, a workweek is a fixed, recurring block of 168 hours — seven consecutive 24-hour days. It doesn’t have to start Monday or match the calendar week. An employer can set it to begin Wednesday at 6 a.m. if that fits the business. Once set, it stays consistent.
The workweek, not the pay period, drives overtime. Any covered employee who works more than 40 hours in a single workweek must be paid at least one and a half times the regular rate for those extra hours.1Office of the Law Revision Counsel. 29 U.S. Code 207 – Maximum Hours A biweekly pay period covers two workweeks, and you cannot average hours across them. If someone works 50 hours in week one and 30 in week two, they are owed 10 hours of overtime for week one, even though the two-week total is 80.
Once a pay period closes, there is a processing lag of roughly three to seven business days while the employer verifies time records, calculates taxes and deductions, and funds the payroll account. Payday arrives at the end of that lag. That’s the reason your paycheck covers work you did last week or last month, not work you’re doing today.
What Federal and State Law Require
The Fair Labor Standards Act doesn’t mandate a specific pay frequency. It requires that wages be paid on the “regular payday for the pay period covered.”2United States Department of Labor. Handy Reference Guide to the Fair Labor Standards Act Pick a schedule, keep it consistent, and the federal side is satisfied.
State law is stricter. Many states set minimum frequencies, often at least semimonthly for most workers, and a few require weekly pay in specific industries. When state law sets a tighter schedule than the employer would prefer, the state rule controls.
The penalties for getting pay timing or amounts wrong come in layers. For repeated or willful violations of the FLSA’s minimum wage or overtime provisions, the Department of Labor can assess civil penalties up to $2,515 per violation as of the most recent adjustment, with the figure adjusted annually for inflation.3U.S. Department of Labor. Civil Money Penalty Inflation Adjustments Employees who weren’t paid properly can also sue for back wages plus an equal amount in liquidated damages, effectively doubling what they are owed. A willful FLSA violation can bring criminal penalties of up to $10,000 and six months in prison, though criminal prosecution is rare.4Office of the Law Revision Counsel. 29 USC 216 – Penalties
Tax Deposits Tied to Your Cycle
Running payroll creates tax obligations that follow their own calendar. Federal income tax and FICA withholdings don’t sit in your account until the quarter ends. They must be deposited on a schedule the IRS assigns to the business.
Which schedule you follow depends on your lookback period liability. If you reported $50,000 or less in employment taxes during the lookback period, you are a monthly depositor: taxes on payments made during a given month are due by the 15th of the following month. If your lookback liability exceeded $50,000, you are on a semiweekly schedule, with deposits due within a few days of each payday.5Internal Revenue Service. Topic No. 757, Forms 941 and 944 – Deposit Requirements
Most employers also file Form 941 each quarter to report wages, tips, and employment taxes. Quarterly filing deadlines are April 30, July 31, October 31, and January 31 of the following year. If all taxes were deposited on time throughout the quarter, the IRS grants an extra 10 calendar days to file.6Internal Revenue Service. Employment Tax Due Dates
Late deposits carry escalating penalties. A deposit 1 to 5 days late costs 2% of the unpaid amount. At 6 to 15 days late, the penalty rises to 5%. Beyond 15 days it reaches 10%, and after the IRS sends a formal demand for payment, it climbs to 15%.7Internal Revenue Service. Failure to Deposit Penalty These penalties stack with interest.
Final Paychecks and the End of the Cycle
When someone leaves, whether they quit or are fired, the last paycheck follows its own timing rules. Federal law does not require immediate payment. The FLSA simply requires the final check by the next regular payday for the pay period in which the separation occurred.8U.S. Department of Labor. Last Paycheck
State law is where the real deadlines live, and they vary sharply. Some states require final pay on the employee’s last day when the termination is involuntary. Others allow up to the next scheduled payday or a set number of days. Missing a state deadline can be expensive: some states impose waiting-time penalties that accrue daily wages for each day the final check is late, up to a statutory cap. If the regular payday has come and gone with no check, the employee can file a complaint with the Department of Labor’s Wage and Hour Division or the state labor agency.8U.S. Department of Labor. Last Paycheck
An employer who fails to pay wages owed under the FLSA can be liable for the unpaid amount plus an equal amount in liquidated damages. Courts are required to award those damages unless the employer proves it acted in good faith and had reasonable grounds to believe it was complying — a defense that rarely succeeds when the violation is simply not paying someone on time.4Office of the Law Revision Counsel. 29 USC 216 – Penalties
