Federal time clock rounding rules let an employer round your recorded start and stop times to the nearest 5 minutes, 6 minutes (one-tenth of an hour), or 15 minutes — but only if the rounding balances out over time so you’re paid for every minute you actually worked. That neutrality requirement is the whole legal test. Rounding that consistently favors the company violates federal wage law, and some states now restrict the practice further.
What Federal Law Actually Permits
The Department of Labor’s regulation at 29 CFR 785.48(b) accepts rounding to the nearest five minutes, tenth of an hour, or quarter-hour. The rule isn’t framed as a right; it’s framed as a practice the DOL will tolerate for enforcement purposes, on one condition: the rounding cannot, over a period of time, result in employees being underpaid for hours actually worked.1eCFR. 29 CFR 785.48 – Use of Time Clocks
That “over a period of time” phrase does the heavy lifting. One punch that costs you two minutes isn’t a violation on its own. A pattern of punches that shaves minutes off the front of every shift while never adding minutes at the end is. The DOL examines whether the rounding averages out across a representative pay period, not whether each individual punch is fair.
How the Seven-Minute Rule Works
Most employers who round use fifteen-minute increments, and the system runs on a single breakpoint: the seventh minute. Punch in one to seven minutes past a quarter-hour and the recorded time rounds backward. Punch in at eight to fourteen minutes and it rounds forward to the next quarter-hour.2U.S. Department of Labor. Fact Sheet 53 – The Health Care Industry and Hours Worked
Concretely: clock in at 8:05, recorded as 8:00. Clock in at 8:09, recorded as 8:15. Leave at 5:07, recorded as 5:00; leave at 5:08, recorded as 5:15. Applied honestly in both directions, you’ll sometimes gain minutes and sometimes lose them, and the results wash out.
Six-minute rounding divides each hour into tenths, which converts cleanly to decimal payroll (six minutes equals 0.1 hours). Its breakpoint sits at three minutes. Five-minute rounding uses a two-and-a-half-minute midpoint. Both tighter intervals cap any single shift at a two- or three-minute swing, which makes lopsided results harder to hide.
When Rounding Becomes Illegal
The neutrality requirement fails when rounding runs in only one direction. If workers routinely arrive a few minutes early because they’ve been told to be “ready to work” at shift start, but leave right at the scheduled end, quarter-hour rounding will consistently trim time off the front and never add it at the back. That’s exactly the pattern the rule prohibits.
The same problem hits overtime harder than regular pay. The DOL uses this example: an employee scheduled eight hours a day, five days a week, who consistently clocks out twelve minutes after her shift ends. Under fifteen-minute rounding, twelve minutes falls below the eight-minute threshold and rounds to zero every day. Five days of that is a full hour of uncompensated work — and because she already worked her 40 scheduled hours, that lost hour was owed at the overtime rate.2U.S. Department of Labor. Fact Sheet 53 – The Health Care Industry and Hours Worked Multiplied across a workforce and back through years of pay periods, that’s serious money.
Rounding and Meal Breaks
Short rest breaks of twenty minutes or less count as paid work time under federal law, so rounding around them doesn’t usually change your total compensable hours.3U.S. Department of Labor. Fact Sheet 22 – Hours Worked Under the Fair Labor Standards Act
Unpaid meal periods are different. A meal break must be at least thirty minutes with the employee fully relieved of duties to qualify as unpaid.4eCFR. 29 CFR Part 785 – Hours Worked If you clock out for lunch at 12:02 and back in at 12:28, your actual break was 26 minutes, even if the system rounds it to a clean 12:00–12:30. You weren’t actually relieved for the full half hour. In Donohue v. AMN Services, the California Supreme Court held that rounding is incompatible with meal period requirements because even small infringements trigger penalties.5California Supreme Court. Donohue v. AMN Services, LLC
What Employers Owe When Rounding Fails the Test
When rounding consistently underpays workers, the costs stack. The employer owes back wages for every unpaid minute. On top of that, the Fair Labor Standards Act imposes liquidated damages equal to the unpaid wages, which effectively doubles the bill. Employees who sue can also recover attorney’s fees and court costs.6Office of the Law Revision Counsel. 29 USC 216 – Penalties
For repeated or willful violations, the DOL can also assess civil money penalties. As of January 2025, that penalty is up to $2,515 per violation, and it adjusts annually for inflation.7U.S. Department of Labor. Civil Money Penalty Inflation Adjustments
The look-back window is two years from the date of the violation, extended to three years if the conduct was willful — meaning the employer knew or should have known it was violating the law.8Office of the Law Revision Counsel. 29 USC 255 – Statute of Limitations A rounding scheme that always rounds clock-ins up and clock-outs down has an obvious willfulness problem.
State Rules That Go Further
Federal law sets the floor. California has raised the ceiling. In Camp v. Home Depot, a California appeals court held that an employer who could and did capture exact minutes worked couldn’t fall back on a quarter-hour rounding policy that left the employee underpaid. The court’s logic: if your system already records the real numbers, rounding that costs the worker pay isn’t a simplification, it’s a taking.9Justia. Camp v. Home Depot U.S.A., Inc.
Paired with Donohue on meal periods, that ruling has made rounding a high-risk practice for California employers, and most have moved to paying by exact minutes. Other states vary in how closely they follow the federal framework, and state wage and hour laws often add remedies of their own — larger liquidated damages, longer statutes of limitations, or state class action procedures. A rounding policy that survives federal review can still lose under state law. If your state has its own wage and hour agency, its guidance is worth checking.
Why Rounding Is Disappearing
Rounding made sense when payroll was done by hand. Modern time-and-attendance software captures punches to the second and does the math instantly, and courts, particularly in California, have started asking why an employer rounds at all when precise tracking is available. Employers who continue rounding need a defensible answer. For anyone working under one of these policies, the practical takeaway is to compare your actual punches against your paystubs across a few pay periods. If the rounding runs in only one direction, that’s the pattern federal law prohibits, and it’s the pattern that unlocks back pay, doubled damages, and — where willfulness applies — a third year of recovery.
