Getting paid on the 1st and 15th means your employer runs a semi-monthly payroll: your annual pay is split into exactly 24 checks a year, with each one covering roughly half a month of work. The rhythm lines up neatly with monthly bills, but the gap between checks is not always the same length, and taxes, benefits, and overtime each behave a little differently on this schedule than on a weekly or bi-weekly one.
How the Two Pay Periods Work
A semi-monthly schedule divides every month into two pay periods. The first runs from the 1st through the 15th. The second runs from the 16th through the last day of the month. Your employer processes each period and issues payment on or shortly after it closes, typically on the 15th and the 1st of the following month. The exact timing depends on how long the company’s payroll processing takes.
The first half of the month is always 15 days. The second half can be 13, 14, 15, or 16 days depending on the month. For salaried employees that variation doesn’t change the paycheck amount. For hourly workers, the number of workdays on each check shifts throughout the year.
When the 1st or 15th Falls on a Weekend or Holiday
Payday will occasionally land on a Saturday, Sunday, or a bank holiday recognized by the Federal Reserve.1Federal Reserve Financial Services. Holiday Schedules Most employers handle this by moving payday to the preceding Friday, which is consistent with how the ACH Network processes payroll transactions.2NACHA. The ABCs of ACH
Some banks and credit unions post direct deposits a day or two before the official payday because the bank fronts the funds ahead of ACH settlement. Whether you get that early access depends on your bank’s policy, not your employer’s schedule.
How Your Paycheck Is Calculated
Salaried Employees
If you’re on salary, divide your annual pay by 24. A $72,000 salary produces a $3,000 gross check every pay period, regardless of how many workdays fall in that half-month. Your gross stays flat whether February’s second half has 13 days or August’s has 16.
Hourly Employees
Hourly checks reflect the actual hours worked in that specific pay period. A standard 40-hour week works out to about 2,080 hours a year, or roughly 86.67 hours per semi-monthly period on average. Some periods will have more workdays than others, so the check size fluctuates. Payroll systems track your real hours for each half-month rather than paying a smoothed average.
Uneven Gaps Between Paydays
The gap between checks isn’t constant. From the 1st to the 15th is always 14 days. From the 15th to the 1st of the next month can stretch to 16 days in a 31-day month, or shrink to about 13 in February. That longer stretch can create a tighter window for covering expenses, so it helps to assign specific bills to each pay period rather than treating both checks as identical.
Taxes and Benefit Deductions on Each Check
Your employer withholds federal income tax from each of your 24 paychecks using IRS percentage-method tables built for semi-monthly pay. Payroll calculates an adjusted annual wage from your W-4, applies the tax brackets to get an annual withholding figure, then divides by 24 to reach the per-paycheck amount.3IRS. 2026 Percentage Method Tables for Automated Payroll Systems
Social Security and Medicare (FICA) come out of every check. In 2026, the Social Security rate is 6.2 percent on earnings up to $184,500, and the Medicare rate is 1.45 percent on all earnings with no cap.4Social Security Administration. Contribution and Benefit Base Your employer matches both.
Health, dental, vision, and other benefit premiums are typically split evenly across your two monthly checks. A $300 monthly health insurance contribution shows up as $150 on each paycheck. That even split is one of the practical advantages of semi-monthly pay: the math works out cleanly every month.
Overtime Gets Complicated for Hourly Workers
Overtime is the trickiest part of this schedule if you’re a non-exempt hourly worker. Federal law requires at least one and one-half times your regular rate for every hour over 40 in a single workweek.5Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours “Workweek” means a fixed seven-day period that doesn’t move.
A semi-monthly pay period doesn’t line up with workweeks. If your workweek runs Sunday through Saturday but your pay period ends on the 15th, one workweek can straddle two paychecks. Overtime still has to be calculated on the full workweek. Employers cannot average hours across two or more weeks to reduce what they owe.6U.S. Department of Labor. Fact Sheet #23 – Overtime Pay Requirements of the FLSA
Overtime earned in a particular workweek must be paid on the regular payday for the pay period in which that workweek ends.7eCFR. 29 CFR 778.106 – Time of Payment In practice, that can mean an overtime adjustment shows up on a later check once the split workweek is complete. If you track your own hours, watch full workweek totals, not just the hours inside each pay period.
How This Differs From Bi-Weekly
Semi-monthly and bi-weekly are the two schedules people most often confuse. Semi-monthly is tied to calendar dates (the 1st and 15th) and produces 24 checks a year. Bi-weekly pays every two weeks on the same day of the week, usually every other Friday, and produces 26 checks a year.
That difference changes the size of each check. For someone earning $60,000 a year:
- Semi-monthly (24 checks): $2,500 gross per paycheck
- Bi-weekly (26 checks): about $2,308 gross per paycheck
Annual gross is identical. Only the per-check amount and the number of paydays change. Bi-weekly gives you two three-paycheck months a year, which can feel like a windfall. Semi-monthly gives you exactly two checks every month, no exceptions, which some people prefer for budgeting.
State Rules That May Restrict This Schedule
Federal law doesn’t dictate pay frequency. The FLSA sets rules for minimum wage, overtime, and recordkeeping, but the choice of payday schedule is largely left to employers and state law. Several states restrict who can be paid semi-monthly.8U.S. Department of Labor. State Payday Requirements
Common restrictions include:
- Some states require hourly employees to be paid weekly or bi-weekly and allow semi-monthly pay only for salaried workers.
- Some states require workers classified as manual laborers to receive weekly pay, with semi-monthly available only through special approval from the state labor department.
- A few states permit monthly pay only above a salary threshold or with written consent, effectively making semi-monthly the minimum frequency for most workers.
If your employer switches you between schedules, check your state labor department’s site to confirm the new schedule is allowed for your job classification.
Your First Paycheck at a New Job
Starting mid-period means a prorated first check. If you start on the 10th and the pay period runs the 1st through the 15th, that first check covers only five or six workdays instead of the usual ten. Depending on your start date and the employer’s processing timeline, you could wait two to three weeks before the first deposit hits your account. Plan for that gap if you have bills due soon after you start.
If Your Employer Pays Late
If an employer violates the FLSA by failing to pay required wages, including overtime, affected employees can recover the unpaid amount plus an equal amount in liquidated damages, along with attorney’s fees.9Office of the Law Revision Counsel. 29 USC 216 – Penalties Most states also impose their own penalties for late wage payment, which can include fixed fines per violation, a percentage of unpaid wages, or both. Repeated or willful violations can rise to criminal sanctions in some jurisdictions.
If payday keeps slipping, document the dates and amounts you were owed and when you actually received them. From there, you can file a complaint with your state labor agency or the U.S. Department of Labor’s Wage and Hour Division.
