53 Fridays: The 2021 Pay Period Leap Year

We have reached the first non-holiday Friday of 2021, which means today is the first payday for many employers (including my own). 2021 is one of those years that come along every 5, 6 or 11 years, depending on your exact pay period and payroll calendar.

The Pay Period Leap Year

The Pay Period Leap Year doesn’t really exist. It’s just the phrase I’ve coined to explain a phenomenon that is critically important for large employers or employers with largely salaried workforces, in particular, because (1) it can have a substantial impact on your bottom line and (2) it only happens roughly once per decade.

What is a “Pay Period Leap Year”? Put simply, Pay Period Leap Years are years with an extra payroll period. Like the Gregorian calendar created by Pope Gregory XIII in 1582, the bi-weekly payroll calendar doesn’t fit evenly into a single, 365-day year.  The Gregorian calendar addresses this problem by adding 1 day every four years at the end of February, just as we did in 2020.  The bi-weekly payroll calendar “adjusts” by adding a 27th pay period every (roughly) 11 years. For employers on a weekly payroll cycle, it happens twice as often.  2021 has 53 Fridays which means that, for many employers, 2021 will be a Pay Period Leap Year (if you didn’t already celebrate one in 2020).

For employers with weekly pay periods, each year has 52 weeks (where each week is exactly 7 days) plus 1 additional day (non leap years) or 2 additional days (if it is a leap year, like 2020). Similarly, for employers with bi-weekly pay periods, 26 bi-weekly periods only account for 364 days each year, not 365 (or 366 in leap years). Those extra days add up, and when the calendar aligns, employers will periodically face an extra pay period for employees that they pay on a weekly or bi-weekly basis. Those are “Pay Period Leap Years.” If you pay employees weekly, your Pay Period Leap Year will occur every five or six years. If you pay bi-weekly, your Pay Period Leap Year will occur every 11 years or so.  2021 will be a leap year for the majority of employers, but your exact cycle will also depend on the last day of your workweek, when you close your pay period and issue paychecks, when direct deposits are processed, and how you deal with bank holidays. This post will outline the most common situation for 2021.

Determining if 2021 is a Pay Period Leap Year for Your Business

If the year starts on a Friday in a non-leap year, like 2021, you end up with 53 Fridays. (If either of the first two days lands on a Friday during a leap year, then you can also get 53 Fridays). For the majority of employers who pay employees on Fridays, this means that 2021 will be a Pay Period Leap Year (if you didn’t celebrate one in 2020, which was a leap year that began on a Wednesday)!

You have a Pay Period Leap Year in 2021 if:

  • your first weekly paychecks will issue on Friday, January 1, 2021; OR
  • your first bi-weekly paychecks will issue on Friday, January 1, 2021.

In the former case, you will have a fifty-third pay period on December 31, 2021. In the latter case, you will have a twenty-seventh pay period on December 31, 2021

Of course, this depends on bank holiday processing rules. Many employers do not date paychecks for a Friday bank holiday, but choose to date them a day earlier and shorten the last pay period before the holiday. Therefore, you will not have a Pay Period Leap Year in 2021 if:

  • your last 2020 weekly paychecks issued on Thursday, December 31, 2020; OR
  • your last 2020 bi-weekly paychecks issued on Thursday, December 31, 2020.

In this case, your Pay Period Leap Year was likely in 2020 because there were 52 Fridays plus the one Thursday (or 53 Thursdays, depending on how you want to look at it). For those of you who just completed a Pay Period Leap Year, please keep reading, because you might need to make adjustments if you have overpaid employees.

The Importance of a Pay Period Leap Year to the Bottom Line

This issue applies only to certain salaried employees.  Hourly employees never experience a pay period leap year because they receive pay for the actual number of hours they work.  Employees paid a salary on a monthly or semi-monthly basis receive either 12 or 24 paychecks per year, no matter what.  However, salaried employees (whether exempt or non-exempt) who normally receive their annual salary on a bi-weekly or weekly basis will have 27 pay periods (or 53, if you pay weekly) this year. This group falls into the category of salaried employees impacted by the Pay Period Leap Year. Take a look at the math:

If you pay an employee $52,000 per year on Fridays, you would pay them $1,000 in each of 52 weekly pay periods or $2,000 in each of 26 bi-weekly pay periods. If you changed nothing in 2020 (like paying a day early on Thursday, December 31), in a Pay Period Leap Year like 2021, you would pay the employee $53,000 over 53 weekly pay periods (a 2% raise) or $54,000 over 27 bi-weekly pay periods (a 4% raise).

Employer Takeaways: Handling Pay Period Leap Years

As I alluded to above, paying employees extra money over the course of a year could have a significant financial and cash flow impact for employers of all sizes. The changes raise wage and hour issues, too, no matter where your employees are located. Here are three options for handling the 2021 Pay Period Leap Year if you pay employees on a weekly or bi-weekly basis (again, employers on monthly and semi-monthly pay periods never have Pay Period Leap Years).  Even if you have now paid 1 or 2 payrolls in 2021, you are not too late.

Option 1: Pay the same amount in each pay period in 2021 as you did in non-Pay Period Leap Years.

As an employer, the Pay Period Leap Year does not require you to do anything in 2021, though that decision comes with a cost.  Salaried employees paid on a weekly or bi-weekly basis will receive either a 2% or 4% pay raise in Pay Period Leap Years like 2021. This is the simplest approach, and presents little legal or practical risk if you communicate it to employees (what employee complains about getting more pay?). For highly compensated employees or those socking away a percentage of their income in your company’s 401(k), this might mean hitting the withholding limit for Social Security earlier, triggering additional Medicare tax withholding, or reaching the limit on 401(k) contributions specified by the IRS. Paying additional 2% or 4% more in salary may impact other retirement contributions, too, triggering either penalties for employees or refund requirements for employers.  Most payroll systems and accounting departments account for these limits, though.

The key for this option is to notify employees that you are doing it.  Many employers in 2021 get a once-in-a-decade opportunity to tout a temporary pay raise for employees.  If you can swing it financially, consider this option. Most importantly, though, your notice should remind employees that the pay increase is temporary and that their annual pay will go back to normal after the Pay Period Leap Year when they again have 52 (or 26) pay periods.

Option 2: Divide the total salary by 53 (or 27) pay periods rather than 52 (or 26).

Option 2 is revenue neutral.  At the end of the year, employees impacted by the Pay Period Leap Year in 2021 will receive exactly the same salary as in non-Pay Period Leap Years.  On a week-to-week basis, it also means that employees receive slightly less per paycheck. Using our example above, you would pay an employee with a $52,000 per year salary $981.13 per week (instead of $1000) or $1925.93 every two weeks (instead of $2000) in 2021, slightly less than in non-Pay Period Leap Years. Other than the potential employee morale issues, lowering the weekly or bi-weekly salary amount could put lower-paid employees below the current $684 salary threshold (which increased effective January 2020, and could increase again under a Biden administration DOL) and jeopardize their exempt status under the FLSA or state laws. Even if you have already paid 1 or 2 payrolls this year, you can still spread the extra payroll over the remaining periods. The longer you wait, though, the bigger impact this option has on employees’ gross pay.

Option 3: Adjust only the last paycheck of the Pay Period Leap Year.

As with the second option, employees receive the same total pay for the year. However, this option only works for some salaried, exempt employees, since the reduction for salaried, non-exempt employees, among others, could result in violations of the FLSA’s minimum wage rules or state minimum wage and wage payment laws. This option is fraught with legal danger, and gives employees a nasty surprise at the end of the year, even when you tell them now that this is the approach you plan to use.

In some cases, though, your option might be already selected by virtue of employment agreements, offer letters, or collective bargaining agreements. If those documents provide for a specific weekly or bi-weekly salary only and do not express wages in terms of an annual rate, then you likely have no choice to make: you must select the first option, even though this means employees receive an extra paycheck because of the Pay Period Leap Year.  If those documents express wages in terms of an annual salary only, then you need to choose one of the three options above.

If 2021 is a Pay Period Leap Year, plan now for how to handle it and notify employees as soon as possible. Due to the many variations in how payroll deposits work, the days of the week when employers issue payroll, and payroll processing around bank holidays, not every employer will face a Pay Period Leap Year in 2021.  Check now to ensure that you have adjusted your payroll schedule, benefit plans, and employee communications before too much of 2021 has slipped away.

  1. Hi,

    I found your blog and I wanted to reach out for some advice. I just started a job and I was given an offer letter with a guaranteed base bi-weekly salary. I accepted the position on that basis. I received my first paycheck and it was just over $100 lower than it should have been. HR explained that this is because there are 27 pay periods in 2021, but I missed the first one. They paid employees out on Jan 1st for time worked in December and I started on Jan 4. Now they sent me a letter saying that my pay has been changed permanently to that lower amount, even though I was offered a job with a promised biweekly salary now they’re refusing to pay it and trying to give me an amount I never agreed to. They divided my pay by 27 pay periods even though I will only have 26 pay periods. I’m so frustrated and very upset. I keep going back and forth telling them that I will be several thousand dollars short at the end of the year if they continue to pay me this way. Any advice?

    1. Alicia,

      Thank you for posting. I obviously can’t give you legal advice, and would encourage you to seek out an attorney in your jurisdiction who practices employment law. Any advice would depend on your exact situation: where you live and work (and what laws apply to you), what the pay rate is, what your job is, what exactly these communications said, etc. There are situations where employers can change pay rates, even decrease them, as I explain in here. It is good that hear that you are continuing an open dialogue with your employer, as that is often a good way to resolve situations like these.
