Twice a month pay, also called semimonthly pay, works by splitting your annual wages into 24 paychecks issued on two fixed calendar dates each month, most often the 1st and the 15th or the 15th and the last day of the month.1ADP. 2026 Payroll Calendar – How Many Pay Periods in a Year If you earn $60,000 a year on salary, each gross check comes to $2,500 before taxes and deductions, every time.
The Paydays and the Pay Periods Behind Them
Each payday closes out a pay period. On a 1st-and-15th schedule, one period runs from the 16th of the prior month through the end of the month, and the next runs from the 1st through the 15th. The dates themselves stay put regardless of whether the month has 28, 30, or 31 days.
That means the two halves of a month are not always the same length. February’s second half might be 13 days; March’s second half might be 16. For salaried workers this makes no difference, because the paycheck is a flat share of annual pay. For hourly workers it does, because actual hours worked in each period drive the check.
How Much Each Paycheck Is
For salaried employees the math is one step: divide your annual salary by 24. Someone earning $72,000 sees $3,000 gross per check, every check, all year. The consistency is the main appeal of the schedule.
Hourly employees see more variation. A standard full-time year is 2,080 hours, which averages about 86.67 hours per semimonthly period, but payroll runs on actual hours worked, not the average. Expect some drift from one check to the next depending on how many workdays fell inside each period.
When a salaried employee starts or leaves in the middle of a pay period, the check is prorated by workdays, not calendar days. If the period contains 11 business days and you worked 4 of them, you receive 4/11 of the normal gross amount.
When Payday Lands on a Weekend or Holiday
The ACH network that moves direct deposits does not settle on weekends or on Federal Reserve holidays, of which there are 11 a year including Juneteenth.2Federal Reserve Bank of St. Louis. Federal Reserve Bank Holiday Schedule Most employers respond by moving the payday to the preceding business day. If your normal payday is a Monday holiday, expect the deposit the Friday before.
What Comes Out of Each Check
Every deduction is either a mandatory tax withholding or a voluntary benefit you elected. Both are spread across all 24 pay periods.
Federal Taxes
Your employer’s payroll system uses the IRS’s semimonthly withholding tables in Publication 15-T, along with the elections on your W-4, to calculate federal income tax on each check.3Internal Revenue Service. 2026 Publication 15-T – Federal Income Tax Withholding Methods Social Security tax is 6.2% of gross pay up to $184,500 in 2026 earnings, and Medicare tax is 1.45% with no cap.4Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Once year-to-date earnings pass $184,500, Social Security withholding stops and later checks in the year get larger.
Retirement and Health Accounts
Pre-tax contributions to a 401(k) or HSA are split evenly across the 24 pay periods. The 2026 employee 401(k) limit is $24,500, which works out to about $1,021 per semimonthly check if you spread the maximum evenly.5Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 HSA limits for 2026 are $4,400 for self-only coverage and $8,750 for family coverage.6Internal Revenue Service.

Insurance and Garnishments
Monthly insurance premiums divide cleanly in half. A $500 monthly health premium becomes $250 per check. Federal law caps ordinary wage garnishments at the lesser of 25% of disposable earnings or the amount above $471.25 per semimonthly period.7U.S. Department of Labor.

Overtime for Hourly Workers
Federal law calculates overtime by the workweek, not by the pay period. Any hours over 40 in a single workweek must be paid at 1.5 times your regular rate, and hours cannot be averaged across two weeks or two pay periods to avoid it.8Office of the Law Revision Counsel. 29 U.S. Code 207 – Maximum Hours9U.S. Department of Labor. Handy Reference Guide to the Fair Labor Standards Act
Semimonthly pay periods rarely line up with workweeks. A period ending on the 15th could fall on a Wednesday, splitting the workweek in two. When that happens, the employer totals the full workweek’s hours to see whether overtime kicked in, and any overtime pay is added to the check for the period in which the workweek ends.10U.S. Department of Labor.

Twice a Month Pay vs. Every Other Week
Semimonthly and biweekly sound alike and get mixed up constantly, but they are not the same. Twice a month gives you 24 paychecks a year on fixed calendar dates. Every other week gives you 26 paychecks a year on a repeating day of the week.1ADP. 2026 Payroll Calendar – How Many Pay Periods in a Year Annual pay is the same either way, but the per-check number changes.
On a $50,000 salary, each semimonthly check is roughly $2,083 gross; each biweekly check is about $1,923. Biweekly employees get two months a year with three paychecks; semimonthly employees never do. The trade-off is that semimonthly paydays sit neatly next to monthly rent, mortgage, and insurance due dates, and monthly deductions split evenly into every check.
When State Law Restricts the Schedule
Not every employer is free to choose semimonthly pay. Massachusetts requires hourly employees to be paid weekly or biweekly and allows semimonthly pay only for salaried workers. New York requires weekly pay for manual workers unless the employer secures state approval to pay semimonthly. New Hampshire and Rhode Island also require permission from the state labor department before an employer can pay less frequently than biweekly.11U.S. Department of Labor.
