Short answer No. What is mandatory is keeping an electronic record of each person's working time. The law does not mention time clocks or devices of any kind. ## Why people talk about a "mandatory time clock" Because the wall-mounted clock is the best-known way to record clock-ins and clock-outs. But article 132, section XXXIV, only asks that the record be electronic and include the start and end time. ## Ways to comply - An app on each person's phone. - A shared tablet at the entrance. - A clock connected to a system. All three comply if they generate an electronic record per person that you can hand over. ## Which one suits you If you have several branches, field staff or remote work, a fixed device leaves people out. A phone does not. ## 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 | Decree published in the Official Gazette of the Federation on May 1, 2026, second and fourth transitory provisions, and article 68 of the LFT. Each change applies from January 1. ## Common mistakes - Assuming the obligation does not apply because you are a small business. - Believing a device or fingerprint is required. - Confusing the date the law took effect with the date of the STPS rules. - Reading the 2030 caps as if they already applied. - Trusting a provider that claims to be certified by the authority. ## What to do now 1. Read what article 132, section XXXIV, requires. 2. Review how you record your staff's clock-in and clock-out today. 3. Choose an electronic recording method. 4. Agree on it in writing with each person. 5. Check the STPS general rules when they are published. ## Related terms **[Vacations by law: how many days are owed](https://sicheca.com/en/blog/vacaciones-por-ley).** With one year of work, 12 days of vacation are owed. **[IMSS contributions: what they are and who pays them](https://sicheca.com/en/blog/cuotas-del-imss).** Employer-employee contributions are the payments to the IMSS that fund social security. **[What is attendance control](https://sicheca.com/en/blog/control-de-asistencia).** Attendance control is any means of knowing who came to work and at what time. ## Frequently asked questions ### Can I keep using my current time clock? Yes, if it stores records electronically and you can hand them over per person. A clock that prints cardboard cards does not comply. ### Who monitors compliance? The Ministry of Labor and Social Welfare, through inspections. ### Where do I find the official text? In the Official Gazette of the Federation of May 1, 2026 and in the current version of the Federal Labor Law published by the Chamber of Deputies. ### Does this replace the advice of a lawyer? No. It is general information. For decisions about your company, consult a labor lawyer. ### Does the law require a particular system? No. It asks that the record be electronic and include the start and end time for each person. ## Legal basis and sources - Electronic working-time record: article 132, section XXXIV, of the LFT and fifth transitory provision of the decree. - Fines: articles 992, 994 and 1002 of the LFT. - [Decree amending the Federal Labor Law on the reduction of the working week](https://sidof.segob.gob.mx/notas/docFuente/5786537).
