How to Fill Out a Timesheet Correctly

A practical walkthrough for employees and supervisors on recording time, breaks, overtime and leave, approving timesheets and fixing errors.

A timesheet is the record your paycheck is built from. For hourly (non-exempt) employees it is also the employer’s proof that every hour was paid correctly, so small habits matter: writing AM or PM, recording the lunch you actually took, initialing corrections. This guide walks through a typical paper or electronic timesheet for employees and the supervisors who approve them. If you need a blank form, use the printable timesheet.

What goes on a timesheet

Field What to enter Example
Employee name and ID Exactly as payroll has it J. Rivera, #1048
Department or job code Where the hours should be charged Shipping
Pay period First and last day covered 10/4/2026 – 10/17/2026
Date One line per day Tue 10/6
Time in / time out Actual start and finish 7:55 AM / 4:31 PM
Meal out / meal in Start and end of an unpaid meal 12:02 PM / 12:32 PM
Daily total Hours worked that day 8.10
Pay code Type of hours REG, OT, PTO, HOL
Weekly total Hours worked in each workweek 42.50
Signatures Employee and supervisor, with dates Signed and dated

Federal recordkeeping rules (29 CFR Part 516) require employers to keep the hours each non-exempt employee works each workday and each workweek, which is why both daily and weekly totals matter.

Record a workday step by step

  1. Time in. Write the time you actually start working, including required tasks such as a pre-shift meeting or setting up equipment. Don’t copy your scheduled start time.
  2. Meal out and meal in. Record when an unpaid meal begins and ends. If you worked through it, leave it blank or write “no lunch”; never record a lunch you didn’t take.
  3. Time out. Write the time you stop working, not the time your shift was supposed to end.
  4. Daily total. Subtract time in from time out, then subtract the meal period.

Worked example (Tuesday): in 7:55 AM, meal out 12:02 PM, meal in 12:32 PM, out 4:31 PM.

Morning: 7:55 AM to 12:02 PM = 4 h 07 min. Afternoon: 12:32 PM to 4:31 PM = 3 h 59 min.

Total: 8 h 06 min = 8 + 6/60 = 8.10 hours.

Write times to the minute unless your employer tells you otherwise; rounding, covered below, is payroll’s job.

Writing times: 12-hour, 24-hour and decimal

  • 12-hour clock. Always include AM or PM. Noon is 12:00 PM and midnight is 12:00 AM; writing “12:00” alone is a classic source of 12-hour errors.
  • 24-hour (military) clock. Hospitals, security firms and transportation companies often use four digits with no colon: 0755 for 7:55 AM and 1631 for 4:31 PM. See how to read military time if your form uses it.
  • Decimal hours. Daily and weekly totals are usually written in decimal hours because pay is rate × hours. Divide the minutes by 60.
Minutes 6 15 20 30 40 45 50
Decimal hours 0.10 0.25 0.33 0.50 0.67 0.75 0.83

So 7 hours 45 minutes is 7.75, not 7.45. The time to decimal calculator converts any value.

Breaks: what to record

Under the Fair Labor Standards Act (FLSA), rest breaks of about 5 to 20 minutes are paid work time (29 CFR 785.18), so don’t deduct them, even if you step away from your work area. A bona fide meal period, typically 30 minutes or more with you completely relieved of duty, can be unpaid (29 CFR 785.19); that is the break you record with meal out and meal in. If you ate while answering calls or watching equipment, it wasn’t a bona fide meal period: record the time as worked, or tell your supervisor. Some states, including California, set their own meal and rest break requirements.

Rounding policies

Many employers round punches to the nearest 5 minutes, 6 minutes (a tenth of an hour) or 15 minutes. With 15-minute rounding, the worked example above becomes 8:00 AM, 12:00 PM, 12:30 PM and 4:30 PM, or 8.00 hours instead of 8.10. Under 29 CFR 785.48(b), that is allowed only if the policy is neutral: it rounds both up and down, so that over time employees are paid for all the time they actually work. A policy that only ever rounds down doesn’t qualify. Employees should write their actual times and let payroll apply the published policy.

Overtime and pay codes

Federal overtime is based on the workweek, not the pay period. Non-exempt employees earn at least 1.5 times their regular rate for hours worked over 40 in a fixed workweek of 168 hours. Weeks can’t be averaged: 30 hours one week and 50 the next means 10 overtime hours, even though the two-week total is exactly 80. Some states add daily overtime: California after 8 hours in a day (double time after 12), Alaska after 8 and Colorado after 12.

Overtime counts whether or not it was approved in advance. Under 29 CFR 785.11, work that is “suffered or permitted” is work time, so record the emails you answered or the task you finished after clocking out. An employer may discipline workers for unapproved overtime, but must still pay for it.

Pay codes separate hours worked from paid time off. Codes vary by employer, but a typical set looks like this:

Code Meaning Counts toward FLSA overtime?
REG Regular hours worked Yes
OT Hours worked over 40 in the workweek Yes
PTO or VAC Vacation or paid time off No
SICK Paid sick leave No
HOL Paid holiday, not worked No
UNP Unpaid leave No

For example, an employee works 9.00 hours Monday, 9.50 Tuesday, 8.00 Wednesday, 10.00 Friday and 6.00 Saturday, and takes Thursday as an 8-hour paid holiday. Hours worked total 42.50, so the timesheet shows 40.00 REG, 2.50 OT and 8.00 HOL, or 50.50 paid hours. The holiday hours don’t create extra overtime under the FLSA, though some policies count them. The time card calculator is a quick way to check the math, and FLSA overtime rules explained covers the details.

This guide summarizes federal rules for general information and is not legal advice. State law, local ordinances and union contracts may be stricter.

Signatures, approvals and deadlines

The employee signs and dates the timesheet to certify that it is complete and accurate. Sign after the last day of the period, never in advance. The supervisor then reviews and approves it. A quick review checklist:

  • Every worked day has both a time in and a time out.
  • Meal periods look realistic, and no lunch is recorded on a day the employee worked through.
  • Daily and weekly totals add up, with decimals converted correctly.
  • Overtime is calculated per workweek, not per pay period.
  • Leave hours carry the right code and match approved requests.

Submit the sheet by your employer’s payroll cutoff, and ask payroll how late or corrected sheets are handled. In most timekeeping systems, electronic approval takes the place of a signature.

Correcting mistakes

On a paper timesheet, never use correction fluid, tape or an eraser. Draw a single line through the wrong entry so it stays readable, write the correct time beside it, and initial and date the change; the supervisor should initial it too. For example, 8:15 AM 7:55 AM, JR 10/6. A missed punch gets the same treatment: write the actual time with a short note explaining why.

In an electronic system, use the edit or missed-punch request so the audit trail shows who changed what and why. Supervisors shouldn’t change an employee’s hours without telling them; any adjustment should be documented and acknowledged.

Record retention

Under 29 CFR Part 516, employers must keep payroll records for at least 3 years, and the time cards and work schedules used to compute wages for at least 2 years. Many states require longer. Employees should keep their own copies of timesheets and pay stubs too: federal back-wage claims can generally reach back 2 years, or 3 years for willful violations.

Common mistakes

  • Writing the schedule (8:00 to 5:00 every day) instead of actual times.
  • Leaving off AM or PM, or writing 12:00 without saying noon or midnight.
  • Writing 7.45 for 7 hours 45 minutes; the correct decimal is 7.75.
  • Deducting paid rest breaks, or recording a lunch that wasn’t taken.
  • Working off the clock: answering messages at home, setting up before clocking in, or finishing tasks after clocking out.
  • Arithmetic errors in totals. If your team keeps time in a spreadsheet, see calculate hours worked in Excel.
  • Signing before the period ends, or forgetting to sign at all.

Frequently asked questions

Should I write the time I arrived or the time I started working?

Write the time you actually began working. Required tasks such as a pre-shift meeting or setting up equipment count as work, while arriving early and waiting on your own time generally does not. If you are unsure what counts, ask your supervisor and follow the written policy.

How do I write 8 hours and 20 minutes as a decimal?

Divide the minutes by 60 and add the result to the hours. 20 divided by 60 is 0.33, so 8 hours 20 minutes is 8.33 hours. Writing 8.20 instead would shortchange you by about 8 minutes.

Can my employer change my timesheet?

Employers can correct genuine errors, such as a missed punch, but they must still pay for all hours actually worked. Changes should be documented and shared with the employee, ideally with the employee's initials or electronic acknowledgment. If hours you worked are removed, raise it with HR or the U.S. Department of Labor's Wage and Hour Division.

Do vacation and holiday hours count toward overtime?

Not under the federal FLSA, which counts only hours actually worked toward the 40-hour threshold. Some employers and union contracts count paid leave anyway, so check your policy. The leave hours themselves are still paid at your normal rate.
