Biweekly and semi-monthly are easy to confuse and are not the same. Biweekly means every two weeks, which is 26 paychecks and two months a year with three of them. Semi-monthly means twice a month, which is 24 paychecks of a consistent size. A biweekly paycheck is smaller than a semi-monthly one on the same salary, because the same money is split more ways.
The three-paycheck months
If you are paid every two weeks, two months each year contain three paydays instead of two. Which months depends on when your employer's cycle starts, and it shifts each year.
This is not extra money. It is the same annual salary arriving in 26 instalments rather than 24, so each one is slightly smaller to compensate. It is useful for planning though, because monthly fixed costs stay flat while two months bring an additional paycheck.
One practical catch: deductions that are charged monthly, such as health premiums, are often spread across only the first two paychecks of the month. On a three-paycheck month the third can be noticeably larger than usual.
Common questions
- What is the difference between biweekly and semi-monthly pay?
- Biweekly is every two weeks, giving 26 paychecks a year with two three-paycheck months. Semi-monthly is twice a month, giving 24 consistent paychecks. On the same salary a semi-monthly paycheck is slightly larger.
- How many paychecks are there in a year?
- Weekly gives 52, biweekly 26, semi-monthly 24 and monthly 12. These are the standard period counts the IRS uses in Publication 15-T to annualise withholding.
- Do I pay more tax if I am paid weekly?
- No. Annual tax is identical whatever the schedule. Withholding annualises each period, so the total across the year works out the same. Only the size and timing of each paycheck differ.
- Which months have three paychecks?
- On a biweekly schedule, two months each year contain three paydays. Which two depends on your employer's pay cycle and shifts annually, so check your own pay calendar.
