Calculator for the fine for not recording working time
Short answer
Enter how many people work without an electronic record and you will see the range of the fine in pesos with the current UMA.
How to do the math by hand
The minimum fine is 250 × $117.31 = $29,327.50. The maximum is 5,000 × $117.31 = $586,550. If the penalty is calculated per person, with 5 people the range goes from $146,637.50 to $2,932,750.
Where the range comes from
From article 994, section IV Bis, of the Federal Labor Law: 250 to 5,000 UMA.
What the calculator does not decide
The exact amount is set by the authority within the range.
Why everything starts with the working-time record
Almost every labor calculation starts from the same data point: how many hours and which days each person worked. If that data is uncertain, so is everything else.
- Overtime: it is paid according to the hours of each week.
- Sunday premium and rest days worked: they depend on which days were worked.
- Aguinaldo and profit sharing: they use the days worked in the year.
- Labor lawsuits: the company must prove the working time.
Since 2026, the Federal Labor Law requires that record to be electronic, per person, with start and end time.
Common mistakes
- Entering net pay instead of gross.
- Not changing the shift type when it is a night or mixed shift.
- Treating the result as if it were the payslip.
- Forgetting that the UMA and the minimum wage change every year.
- Not noting what data the calculation was made with.
What to do now
- Confirm the current value for the year.
- Have each person's daily salary at hand.
- Check the days and hours worked in your record.
- Do the math and keep it.
- Validate it with your accountant.

Are the amounts gross or net?
Gross. They do not account for taxes or social security contributions.
Can I use this for my payroll?
It works as a reference. Your accountant should do or validate the payroll calculation.
