8 and 80 Overtime Rule for Hospital Workers, Explained
Hospitals can pay overtime over 8 hours a day and 80 in 14 days instead of over 40 a week. See how the 8/80 rule works, when it pays more, and how to check it.

Quick Answer: What the 8 and 80 Rule Is
The 8 and 80 rule lets hospitals and residential care establishments use a fixed 14-consecutive-day work period instead of the standard 7-day workweek. Under it, overtime is owed at 1.5 times the regular rate for hours over 8 in a workday and for hours over 80 in the 14-day period.
It comes from section 7(j) of the Fair Labor Standards Act (29 U.S.C. § 207(j)) and is spelled out in 29 CFR 778.601 and DOL Fact Sheet #54.
Two things people get wrong right away. First, 8/80 is an option, not a default: most healthcare employers still use the 40-hour workweek. Second, the two triggers do not stack into double payment. Daily overtime already paid gets credited against the 80-hour obligation.
Key Takeaways
- Every hour past 8 in a day is overtime. A 12-hour shift generates 4 overtime hours even in a 36-hour week.
- Only certain employers qualify. Hospitals, plus care institutions whose patients live on the premises.
- The agreement does not have to be in writing. Plenty of payroll guides claim it does; 29 CFR 778.601 says otherwise.
- Daily premiums are credited, not doubled. You do not get paid twice for the same hour.
- 8/80 favors 12-hour shifts and penalizes six-day, 8-hour weeks. In the comparisons below, one schedule gains $320 a period and the other loses $128.
- Your overtime rate must include your shift differential. This is the single most common healthcare pay error the DOL cites.
Who Can (and Can’t) Use the 8/80 Rule
The statute limits 8/80 to “a hospital or an establishment which is an institution primarily engaged in the care of the sick, the aged, or the mentally ill or defective who reside on the premises.”
That last phrase does most of the work, and it attaches to the non-hospital half of the sentence. A hospital qualifies as a hospital, which the DOL describes as an establishment primarily offering medical and surgical services to patients who generally stay overnight or longer. Every other kind of care institution has to house the people it cares for. If the people being cared for go home at the end of the visit, the employer is out.
Covered:
- Hospitals (including psychiatric and rehabilitation hospitals)
- Nursing facilities and skilled nursing facilities
- Assisted living and residential care facilities
- Intermediate care facilities for individuals with intellectual disabilities
Not covered:
- Outpatient clinics and urgent care
- Physician, dental, and chiropractic offices
- Ambulatory surgery centers
- Standalone labs and imaging centers
- Most home health agencies (the patient resides in their own home, not on the employer’s premises)
The two conditions
Even a qualifying employer has to meet both of these:
- A prior agreement or understanding with the employee, entered into before the work is performed. It cannot be applied retroactively to a pay period that has already been worked.
- Actual payment of 1.5x on both triggers, daily over 8 and period over 80.
The written-agreement myth
Several payroll vendors and PEO guides state flatly that a written agreement is required. They are wrong.
29 CFR 778.601 provides that the agreement “need not be in writing, but if it is not, a special record concerning it must be kept as required by part 516.” So the choice is: write it down, or keep a special record. An unwritten understanding with no record is the actual violation.
How to Calculate 8/80 Overtime, Step by Step
Four steps. The fourth is the one nobody explains.
- Fix the 14-day period. It has to be a recurring, established block of 14 consecutive days. It does not have to start on Sunday or line up with the calendar.
- Count daily overtime. For each workday, any hours past 8 are overtime hours.
- Count period overtime. Total all hours in the 14 days and subtract 80. Anything left over is period overtime.
- Credit the daily premiums against the period obligation. Under 29 CFR 778.601, premium payments already made for daily overtime count toward the 80-hour requirement. Hours are never paid at 1.5x twice.
Worked example: seven 12-hour shifts across 14 days
A med-surg RN earns $32 an hour and works three 12s in week one and four 12s in week two. No differentials, to keep the arithmetic clean.
| Step | Calculation | Result |
|---|---|---|
| Total hours | 7 shifts x 12 hours | 84 hours |
| Daily overtime | 7 shifts x 4 hours over 8 | 28 hours |
| Period overtime | 84 - 80 | 4 hours |
| Credit applied | 4 period hours already inside the 28 daily hours | 0 additional |
| Overtime hours owed | 28 hours | |
| Straight-time hours | 84 - 28 | 56 hours |
The dollars:
- Straight time: 56 x $32 = $1,792
- Overtime: 28 x $48 = $1,344
- Total for the period: $3,136
Notice that the 4 hours of period overtime cost the employer nothing extra. They were already inside the 28 daily overtime hours and got credited. That crediting rule is why the two triggers do not add up to 32 overtime hours. You get whichever count is larger, not the sum.
You can run your own two-week schedule through the biweekly timecard calculator to get the hour totals, then check the premium math with the overtime calculator.
Does 8/80 Pay You More or Less Than the 40-Hour Rule?
The vendor articles skip this one. It depends entirely on the shape of your schedule.
When 8/80 wins: long shifts
Same nurse, same $32 an hour, same seven 12-hour shifts.
| Standard 40-hour rule | 8/80 rule | |
|---|---|---|
| Week 1 (three 12s) | 36 hours, 0 OT | 12 OT hours |
| Week 2 (four 12s) | 48 hours, 8 OT | 16 OT hours |
| Total OT hours | 8 | 28 |
| Straight-time pay | 76 x $32 = $2,432 | 56 x $32 = $1,792 |
| Overtime pay | 8 x $48 = $384 | 28 x $48 = $1,344 |
| Total | $2,816 | $3,136 |
8/80 pays this worker $320 more for the identical 84 hours. Over 26 pay periods that is roughly $8,300 a year.
When 8/80 loses: five and six-day, 8-hour weeks
Now a dietary aide at the same facility, also $32 an hour, working six 8-hour days in week one and four in week two.
| Standard 40-hour rule | 8/80 rule | |
|---|---|---|
| Week 1 (six 8s) | 48 hours, 8 OT | 0 OT (no day over 8) |
| Week 2 (four 8s) | 32 hours, 0 OT | 0 OT |
| Period total | 80 hours | 80 hours, not over 80 |
| Total OT hours | 8 | 0 |
| Total | $2,688 | $2,560 |
Zero overtime. No day crossed 8, and the period landed exactly on 80. Under the standard workweek rule the same 80 hours would have produced 8 overtime hours and $128 more.
No loophole here, just the trade the rule makes: 8/80 rewards compressed schedules and penalizes stretched ones.
Your employer cannot play both sides
Two guardrails in 29 CFR 778.601 keep this from becoming a shell game:
- The 14-day period must be elected “with the intent to use such period permanently or for a substantial period of time.” Switching between systems “to take advantage of less onerous overtime pay liabilities” is not allowed.
- An employer cannot apply both systems to the same employee. It may use 8/80 for nursing staff and the 40-hour workweek for the billing office, but it cannot flip you between them period to period.
If your facility moved you onto 8/80 the month your schedule changed from 12s to 8s, that timing is worth a question to payroll.
Regular Rate Mistakes That Shortchange Healthcare Workers
The DOL names this as the most common overtime error in the industry, and 8/80 does nothing to change it. Your overtime multiplier applies to your regular rate, not your base hourly wage.
Your regular rate has to include:
- Night, evening, and weekend shift differentials
- Non-discretionary bonuses (production, attendance, quality)
- Retention and sign-on bonuses tied to work
- Charge-nurse and preceptor premiums
- On-call pay, in many circumstances
The differential math
A night-shift nurse earns $32 base plus a $4 per hour night differential.
- Wrong: 1.5 x $32 = $48 per overtime hour
- Right: 1.5 x $36 = $54 per overtime hour
Six dollars an hour. Across the 28 overtime hours in the worked example above, that is $168 per pay period, or about $4,370 a year, quietly missing from the check.
Run the numbers with the regular rate of pay calculator and the shift differential calculator, or read the longer walkthrough in Regular Rate of Pay: What Counts for Overtime.
Unpaid hours that should have counted
8/80 makes daily hour totals matter more than usual, because a shift that runs 8.5 hours instead of 8 produces half an hour of overtime, not half an hour of straight time. Watch for:
- Automatic meal-break deductions taken when the break was interrupted or never happened
- Pre-shift and post-shift handoff or report time
- Mandatory training, competency checkoffs, and skills fairs
- Donning and doffing required protective equipment
Each of these lands squarely in overtime territory under 8/80. Logging your actual in and out times with a tool like Timeclock44 gives you a record to hold up next to the paystub when the totals disagree.
8/80 Is Not 9/80
These two get confused constantly, and they have nothing to do with each other.
8/80 is an FLSA overtime calculation method for hospitals and residential care, using a 14-day work period.
9/80 is a scheduling pattern (eight 9-hour days, one 8-hour day, one day off every two weeks) available to any employer, and it still runs on the standard 7-day workweek. Its whole design depends on splitting the 8-hour day across two workweeks so neither week exceeds 40 hours.
More on that one in The 9/80 Work Schedule and Overtime.
State Law and the 2026 Overtime Tax Deduction
State law can beat 8/80
The FLSA is a floor, not a ceiling. Where state law pays more, state law wins.
California requires daily overtime over 8 hours and double time over 12, unless the employer adopts a valid alternative workweek schedule through a two-thirds secret-ballot vote of the affected work unit, with the results reported to the state’s Division of Labor Statistics and Research within 30 days. Even then, hours over 40 in a workweek still trigger overtime. Alaska, Nevada, Colorado, and others impose daily overtime rules of their own.
A California hospital using 8/80 still owes double time past 12 hours in a day, which federal law never requires. Check your state in the overtime rules by state tool and see California Daily Overtime Rules for the details.
8/80 and “no tax on overtime”
Almost nobody covers this wrinkle. For tax years 2025 through 2028, the federal deduction for qualified overtime compensation covers only the premium portion of overtime required by section 7 of the FLSA, capped at $12,500 for single filers and $25,000 for joint filers, phasing out above $150,000 and $300,000 of modified adjusted gross income.
Section 7(j) overtime is required by section 7. So daily-over-8 premiums under 8/80 count as qualified overtime compensation, even in a week that never reaches 40 hours.
Back to the 28-overtime-hour example. The premium portion is the half-time piece: 0.5 x $32 = $16 per overtime hour.
- Under 8/80: 28 hours x $16 = $448 per period, about $11,648 a year across 26 periods
- Under the 40-hour rule: 8 hours x $16 = $128 per period, about $3,328 a year
Same hours worked. Roughly $8,300 more in deductible overtime under 8/80, sitting just under the single-filer cap.
One reporting note: for tax year 2025 employers were not required to separately report qualified overtime on the W-2, so many did not. For 2026 and later, separate reporting is required. If your 2025 W-2 has no overtime figure, your own hour records become the backup. Estimate your own with the overtime tax savings calculator and read No Tax on Overtime for the full picture.

Frequently Asked Questions
What is the 8 and 80 rule?
The 8 and 80 rule is an option under FLSA section 7(j) that lets hospitals and residential care establishments use a fixed 14-day work period instead of the 7-day workweek. Under it, the employer pays 1.5 times the regular rate for hours over 8 in a workday and for hours over 80 in the 14-day period.
Who can use the 8/80 overtime rule?
Only employers operating a hospital or an institution primarily engaged in the care of the sick, the aged, or the mentally ill who reside on the premises. That covers hospitals, nursing facilities, skilled nursing facilities, assisted living, residential care, and intermediate care facilities. Outpatient clinics, physician and dental offices, ambulatory surgery centers, standalone labs, and most home health agencies cannot use it, because they have no residents on the premises.
Does the 8/80 agreement have to be in writing?
No. 29 CFR 778.601 says the agreement need not be in writing, but if it is not written down, the employer must keep a special record of it under 29 CFR Part 516. The agreement or understanding must be in place before the work is performed, so it cannot be applied retroactively to a pay period that has already been worked.
How much overtime do I get for a 12-hour shift under 8/80?
Four hours of overtime for that day. Under 8/80, every hour past 8 in a workday is overtime, even if the week never reaches 40 hours. A nurse who works three 12-hour shifts in a 36-hour week earns 12 overtime hours under 8/80 and zero under the standard 40-hour rule.
Is the 8/80 rule better or worse for workers?
It depends on your schedule. If you work long shifts such as 10s and 12s, 8/80 usually pays more, because every hour past 8 in a day is overtime. If you work five or six 8-hour days, 8/80 can pay less, because you may never cross either threshold. The rule favors compressed schedules and penalizes stretched ones.
Can my employer switch between 8/80 and the 40-hour rule?
Not to chase cheaper overtime. Under 29 CFR 778.601, the 14-day period must be adopted with the intent to use it permanently or for a substantial period of time, and switching back and forth to take advantage of less onerous overtime pay liabilities is not permitted. An employer can never apply both systems to the same employee, though it may use different systems for different employees at the same site.
Does 8/80 overtime count for the no tax on overtime deduction?
Yes. The deduction covers the premium portion of overtime required by section 7 of the FLSA, and 7(j) overtime is required by section 7, so daily-over-8 premiums qualify even in weeks under 40 hours. The cap is $12,500 for single filers and $25,000 for joint filers, for tax years 2025 through 2028, phasing out above $150,000 and $300,000 of modified adjusted gross income.
Does my shift differential change my 8/80 overtime rate?
Yes. Overtime is calculated on your regular rate, which must include shift differentials, non-discretionary bonuses, and retention pay. If you earn $32 base plus a $4 night differential, your overtime rate is 1.5 times $36, which is $54, not $48. Paying overtime on the base rate alone is the error the Department of Labor flags most often in healthcare.
