How to fill out a timesheet

A timesheet is a record that may be read months later by someone who was not there. These are the habits that make it hold up.

Before you start

Three things determine whether your sheet will reconcile with payroll, and all three are worth confirming once rather than guessing every week:

Filling it in, step by step

  1. Write the date, not just the day. "Tuesday" is ambiguous three weeks later when someone queries the sheet.
  2. Record actual start and end times, not totals. A bare "8 hours" cannot be checked against anything. Times can be audited; totals are just an assertion.
  3. Use one format and stick to it. 24-hour time removes the AM/PM ambiguity entirely — see the military time converter if your employer uses it.
  4. Log each shift separately. If you clock out for lunch and back in, that is two shifts, not one shift with a break. Recording it as both double-counts the deduction.
  5. Put unpaid break minutes in their own column. Never quietly shorten your hours to account for a break — the deduction should be visible and challengeable.
  6. Fill it in daily. Reconstructing a week on Friday afternoon is where errors and disputes come from, and a contemporaneous record carries far more weight than a later recollection.
  7. Use the notes column. Project codes, client names, the reason a day was short, "worked through lunch — called back at 12:20". This is the field that resolves arguments.
  8. Total in decimal hours. 7 hours 45 minutes is 7.75, not 7.45 — see the minutes to decimal chart.
  9. Check the total before you submit. Does the weekly figure look right against the days? Is any day above your overtime threshold?
  10. Keep your own copy. Export or photograph it. If a sheet goes missing, the copy you kept is the record.

A filled-in week

What a correct sheet looks like. Note that Wednesday is recorded as two shifts rather than one shift with a break, and that Thursday's overtime is visible rather than smoothed away.

The week is 38 hours, below the 40-hour weekly threshold — but Thursday still generated 2 hours of daily overtime in a state that has a daily rule. That is exactly the case a weekly total alone would hide.

The mistakes that cost money

MistakeWhy it costs you
Writing 7.45 for 7 hours 45 minutesUnderstates by 18 minutes every time. The correct decimal is 7.75.
Deducting a break you also punched out forDouble-counts the deduction, losing 30 minutes a day.
Rounding your own hours down "to be safe"You are not required to. Record what you worked.
Recording totals instead of timesNothing can be verified later, and disputes default against the vague record.
Leaving off pre-shift or post-shift workSetup, handover and closing down are usually compensable time.
Filling the week in from memory on FridayContemporaneous records carry weight; reconstructions do not.
Not keeping a copyIf the sheet is lost or altered, you have nothing.

How long to keep it

Employers covered by the FLSA must retain time records for non-exempt employees for at least two years, and payroll records for three. Keeping your own copy for the same period costs nothing and is the only thing that helps if pay is ever disputed after the fact.

The TimeWorked timesheet keeps entries in your browser and exports a CSV or JSON backup; the blank templates print a sheet with signature lines if your employer wants paper.

Frequently asked questions

How do I fill out a weekly timesheet correctly?

Record the date and the actual clock-in and clock-out times for each shift, put unpaid break minutes in their own column, total in decimal hours, add notes explaining anything unusual, and fill it in daily rather than from memory at the end of the week.

Should I write my hours in decimal or hours and minutes?

Payroll normally wants decimal hours, so 7 hours 45 minutes is entered as 7.75. Writing 7.45 is the single most common timesheet error and understates the time by 18 minutes.

Do I record my lunch break as a break or as two shifts?

If you clock out and back in, record two shifts and leave the break field at zero — the gap is already excluded. Use the break field only when you stay clocked in through an unpaid break.

Should I round my own hours?

No. Record what you actually worked. Rounding is your employer's policy to apply, and rounding yourself down means giving away time nobody asked you to give.

What should I put in the notes column?

Anything that explains the numbers: project or client codes, why a day was short or long, whose shift you covered, and any break you were called out of. This is the field that settles queries months later.

How long should I keep my timesheets?

At least two years. That matches the FLSA record-retention requirement for employers, and it covers the period in which most wage disputes arise.
