Overtime in 2027: how much is allowed and how it is paid
Short answer
In 2027, up to 9 overtime hours per week are allowed, paid at double, with a maximum of 4 per day and on no more than 4 days. If exceeded, up to 4 more hours paid at triple.
The previous rule no longer exists
"Three hours a day, three times a week" stopped applying on May 1, 2026. Now the cap is weekly.
Three limits at once
- Weekly: 9 hours at double in 2026 and 2027.
- Distribution: maximum 4 hours per day, on a maximum of 4 days.
- Daily: workday plus overtime, never more than 12 hours.
How to do the math by hand
Take a salary of $400 per day on a day shift. The ordinary hour is worth 400 ÷ 8 = $50. In 2027, with 11 overtime hours in the week, the first 9 are paid at double time (9 × $100 = $900) and the remaining 2 at triple time (2 × $150 = $300). Total: $1,200.
The reform in one minute
The reform has two parts. On March 3, 2026, article 123 of the Constitution was amended to set the 40-hour workweek. On May 1, 2026, the Federal Labor Law was amended, which is where the detail is.
- The maximum working week drops from 48 to 40 hours, two hours per year, between 2027 and 2030.
- Overtime has a weekly cap: it is paid at double time up to the cap and at triple time for up to 4 more hours.
- Each company must electronically record the start and end time of each person's workday.
- Not keeping that record is fined 250 to 5,000 UMA.
- Salary and benefits cannot go down because of the reduction in hours.
What remains pending are the STPS general rules, which will define who the record applies to and what exceptions there will be. They take effect on January 1, 2027.
| Year | Maximum working hours | Double-time overtime | Triple-time overtime |
|---|---|---|---|
| 2026 | 48 h | 9 h | 4 h |
| 2027 | 46 h | 9 h | 4 h |
| 2028 | 44 h | 10 h | 4 h |
| 2029 | 42 h | 11 h | 4 h |
| 2030 | 40 h | 12 h | 4 h |

Common mistakes
- Adding up overtime by pay period (quincena) instead of by week.
- Forgetting the maximum of 4 overtime hours a day and 4 days a week.
- Not counting as working time the time a person is at the company's disposal.
- Dividing by 8 hours when the shift is night or mixed.
- Paying at double time hours that already correspond to triple time.
What to do now
- Measure actual hours for the last four weeks.
- Identify who exceeds the maximum workweek for the year.
- Redesign the shifts.
- Define who authorizes overtime.
- Check each person's cap every week.
