A 27-paycheck year happens when the calendar lines up so that a biweekly payday falls 27 times between January 1 and December 31 instead of the usual 26. Depending on how your employer handles it, you either get one extra paycheck that year or slightly smaller paychecks spread across all 27. Either way, it can affect your withholding and benefit deductions, so it's worth knowing which approach your employer uses.
Below we explain why 27 pay periods happen, the two ways employers deal with them, and worked examples showing what changes on your paycheck. You can check any per-paycheck amount with the paycheck calculator.
Why some years have 27 pay periods
A year has 365 days, which is 52 weeks plus one extra day (two in a leap year). A biweekly schedule pays you every 14 days, so 26 paychecks cover 364 days. Those leftover days add up, and every so often a payday lands on January 1 or 2 and the cycle squeezes a 27th payday in before the year ends.
The same thing happens with weekly pay: some years have 53 weekly paydays instead of 52. Semimonthly and monthly schedules never have this issue, because they're tied to calendar dates rather than a fixed number of days. Our comparison of biweekly vs semimonthly pay covers that difference in detail.
| Pay frequency | Normal paydays per year | Occasional extra |
|---|---|---|
| Weekly | 52 | 53 |
| Biweekly | 26 | 27 |
| Semimonthly | 24 | None |
| Monthly | 12 | None |
To find out if your next year has 27 pay periods, count your scheduled paydays on a calendar or ask your payroll department.
How employers handle 27 pay periods for salaried staff
Hourly workers are simple: you're paid for the hours you work, so a 27th paycheck is just another two weeks of wages. Salaried employees are where it gets interesting. Employers generally choose one of two approaches.
Option 1: Keep the same paycheck, pay 27 times
Your per-paycheck amount stays at your annual salary divided by 26. You receive 27 of those checks, so your W-2 for that year shows more than your stated salary. The extra check effectively covers work that straddles the year boundary, and it evens out over the long run.
Option 2: Divide your salary by 27
Your employer spreads your annual salary across 27 paychecks, so each one is a little smaller, but your yearly total matches your salary. If your employer does this, you'll usually get notice before the year starts.
Some employers use other variations, such as adjusting only the final paycheck. Your offer letter, employee handbook or HR team can tell you which method applies.
Worked example: a $65,000 salary with 27 pay periods
Let's look at a single filer in Georgia earning $65,000, with no 401(k) or insurance deductions. All figures are estimates from our calculator.
| Item | Normal year (26 checks) | Option 1: 27 x salary/26 | Option 2: salary/27 |
|---|---|---|---|
| Gross per paycheck | $2,500.00 | $2,500.00 | $2,407.41 |
| Federal withholding per check | $216.15 | $216.15 | $205.04 |
| Georgia withholding per check | $105.80 | $105.80 | $100.99 |
| Net per paycheck | $1,986.80 | $1,986.80 | $1,917.21 |
| Total gross for the year | $65,000 | $67,500 | $65,000 |
| Total net for the year | $51,657 | $53,644 | $51,765 |
Under Option 1 you take home about $1,987 more over the year, because you're paid an extra check. Under Option 2 each paycheck is $69.59 smaller, which is something to plan for if your budget is tight.
The withholding catch
Payroll systems calculate withholding as if each paycheck repeats a set number of times per year, usually 26 for biweekly pay. In a 27-paycheck year, that assumption is off, so withholding may not quite match your actual tax.
- Option 1: 27 checks withhold $5,836 in federal income tax, but the estimated tax on $67,500 of wages is $6,020. That's a shortfall of about $184 federal and $24 for Georgia. The extra $2,500 is taxed at your 22% marginal rate, while withholding treats it like an ordinary check.
- Option 2: each smaller check is withheld as if you earned $2,407.41 x 26, or about $62,593 a year. Over 27 checks, federal withholding totals $5,536 against estimated tax of $5,620 on $65,000, a shortfall of about $84 federal and $24 for Georgia.
Social Security and Medicare are flat percentages, so they come out right in either case. These gaps are small and may simply shrink a refund. If you'd rather not owe anything, you can add a few dollars of extra withholding per paycheck in Step 4(c) of your W-4. See why you might owe taxes this year for other common causes.
Hourly example
A single Georgia worker earning $22 an hour for 40 hours a week grosses $1,760 per biweekly check and takes home $1,430.62. In a 27-paycheck year, gross wages for the calendar year are $47,520 instead of $45,760, and take-home rises to about $38,627 from $37,196. Federal withholding falls about $84 short of the estimated tax, and Georgia withholding about $24 short, for the same reason as Option 1.
What happens to benefit deductions
Fixed per-paycheck deductions can be taken 27 times unless your employer adjusts them. Say you pay $100 per paycheck for health insurance and contribute 6% of pay to a 401(k) on the same $65,000 salary:
- Health insurance: 27 x $100 = $2,700 instead of $2,600. Some employers recalculate premiums for the year or skip a deduction on the 27th check, but not all do.
- 401(k): a percentage contribution of $150 per check would total $4,050 over 27 checks. That's well under the 2026 limit of $24,500, but if you set your contribution to hit the limit exactly over 26 checks, a 27th check could push you over or cause contributions to stop early. Check how your plan handles it, especially if your employer match is calculated per paycheck.
- Flexible spending accounts: annual elections are often divided by the number of paychecks, so each deduction may be slightly smaller in a 27-period year.

How to plan for a 27-paycheck year
- Ask your employer which method they use before the year starts.
- Budget on your per-paycheck amount, not your annual salary divided by 12. If checks get smaller under Option 2, adjust your monthly plan.
- Review your W-4 if a small balance due would be a problem. The IRS Tax Withholding Estimator can show if you're on track.
- Check benefit settings, especially 401(k) contributions near the annual limit and fixed-amount deductions.
- Decide what to do with an extra check. If you get one under Option 1, it's a natural chance to top up savings or pay down debt.
Frequently Asked Questions
How often do 27 pay periods happen?
Roughly once every 11 years for a given biweekly schedule, though leap years can shift the timing. Your exact year depends on which day your paydays fall.
Does a 27th paycheck mean I got a raise?
No. Under Option 1, your W-2 shows more wages for that calendar year, but your pay rate hasn't changed. The extra check reflects how paydays fell on the calendar.
Is the 27th paycheck taxed differently?
No. It's regular wages, withheld the same way as any other paycheck. The only difference is that your total wages for the year are higher under Option 1, which can leave withholding a little short.
Can my employer reduce my paychecks for a 27-pay year?
Many salaried employees have pay stated as an annual amount, and some employers divide it by 27 in these years. Check your employment agreement and your state labor department if you have questions about your situation.
