Time Clock Rounding Rules

Time clock rounding is still allowed under federal law, but it is no longer the clean default for employers with modern timekeeping software.

The reason is simple: if your system already records the exact clock-in and clock-out time, rounding creates a second payroll number that may be harder to defend than the original record.

Federal law still gives employers a rounding tolerance. California and Oregon have made that tolerance riskier. And recordkeeping rules mean you need the raw punches if anyone later challenges the policy.

This guide explains what rounding is, when it is allowed, where it is risky, and what an employer should do before keeping or changing a rounding policy.

The Federal Rounding Rule

The federal rule is 29 CFR §785.48(b).

It allows employers to round employee start and stop times to:

• the nearest 5 minutes;
• the nearest one-tenth of an hour, which is 6 minutes;
• the nearest quarter hour, which is 15 minutes.

But there is a condition: the rounding practice cannot, over time, fail to pay employees for all the time they actually worked.

That means the policy has to be neutral in real payroll data, not just neutral in a handbook.

The 7-Minute Rule

Quarter-hour rounding is often called the 7-minute rule.

That looks even on paper. In real workplaces, punch patterns are rarely even. Employees may clock in early because they are setting up, logging in, unlocking, putting on gear, or preparing workstations.

If the same pattern keeps taking minutes away from employees, the policy is not doing what the federal rule requires.

Use the calculator below to compare exact time with a rounded time card. The default shows the 7-minute-rule example from the table.

Why Exact-Time Systems Change The Risk

Rounding was built for a world where exact time was hard to administer. Modern time clocks already capture exact time.

If the exact punch record is already available, rounding creates a harder question: why did payroll pay a different number?

Exact-time pay usually avoids three problems:

• proving the rounding policy averaged out;
• preserving both the raw punch and rounded payroll number;
• defending small differences across many employees and pay periods.

The payroll savings from rounding are usually small. The cost of defending a rounding policy can be much larger.

California: The Main Warning

California used to allow neutral rounding under the federal-style test. See's Candy Shops, Inc. v. Superior Court adopted that approach in 2012, and AHMC Healthcare, Inc. v. Superior Court upheld a workforce-neutral policy in 2018.

Then California narrowed the rule.

Donohue v. AMN Services, LLC held that California employers cannot round meal-period punches. Meal breaks depend on precise timing rules, and rounding can hide a short or late meal period.

Camp v. Home Depot U.S.A., Inc. held that when an employer can capture and has captured exact time, it must pay for all time worked instead of paying rounded time. The California Supreme Court granted review in 2023, so Camp is persuasive while review is pending, not final binding Supreme Court law.

Woodworth v. Loma Linda University Medical Center followed the same direction, and review is also pending.

The practical employer answer: if you have California nonexempt employees and your system captures exact time, turn rounding off unless counsel has approved a specific policy.

What If Camp Changes?

The California Supreme Court could affirm, narrow, or reverse Camp.

That last point matters. Even if Camp changes, meal-period rounding in California remains barred by Donohue.

Oregon: The Second Warning

Oregon is the main state outside California where rounding risk has changed.

In Eisele v. Home Depot U.S.A., Inc., a federal district court held that Home Depot's rounding policy was not permitted under Oregon wage law. It is not an Oregon Supreme Court decision, but it is enough that Oregon employers should treat rounding as high-risk.

Early Punches And Grace Periods

Early and late punches are handled by 29 CFR §785.48(a).

An employer may disregard early or late punch time only if the employee was not working during that period.

This is where grace periods fail. If an employee clocks in early and starts working, that is work time. A grace period cannot turn real work into unpaid time.

Auto-Deducted Meal Breaks

Auto-deducting meal breaks is related but separate from rounding.

Under federal law, auto-deduction can be lawful if employees know how to report missed breaks and the reporting process actually works. But in California, after Donohue, a system that always deducts or rounds meal periods can create a presumption that meal-period rules were violated.

For California employers, actual break punches plus an attestation workflow are safer than automatic deductions or rounded meal times.

Raw Punches Matter

Rounding does not remove the duty to keep records.

29 CFR §516.2 requires records of hours worked each workday and total hours worked each workweek. 29 CFR §516.5 generally requires payroll records for three years. 29 CFR §516.6 requires supplementary wage computation records for two years.

For rounding, keep the raw punch and the paid result. If you keep only the rounded total, you may not be able to prove the policy was neutral.

If records are incomplete, Anderson v. Mt. Clemens Pottery Co. can shift the burden. The employee can estimate unpaid work by a just and reasonable inference, and the employer has to produce better evidence or rebut that estimate.

What Employers Should Do

1. Find every rounding setting in timekeeping, payroll, meal-break, and grace-period rules.
2. Confirm raw punches are preserved.
3. Compare exact time to paid time across employees and pay periods.
4. Stop rounding California meal periods.
5. Use exact-time pay for California and Oregon workers unless counsel approves another setup.
6. Consider exact-time pay company-wide for simplicity.
7. If the audit shows underpayment, talk to counsel before issuing retro pay.

FAQ

The Bottom Line

If your time clock records exact time, rounding is usually more work to defend than it is worth. Federal law may still allow neutral rounding, but California, Oregon, and recordkeeping rules have made exact-time pay the cleaner default.
