It is in Article 71 of the Federal Labor Law. ## Example With $400 per day, each Sunday worked adds $100 of premium. ## How to do the math by hand With $400 per day, the premium for one Sunday is 400 × 25% = $100. If the person worked all four Sundays of the month, it is $400. ## It is not the same as working on a rest day If Sunday was your rest day and you worked, in addition to the premium you are owed double pay for working on a rest day. ## Why you need a record To know which Sundays each person worked. ## 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 - Using the UMA or minimum wage value from a previous year. - Confusing daily salary, integrated salary and contribution base salary. - Calculating benefits without knowing the days actually worked. - Taking the legal minimums as if they were the maximum. - Not keeping the backup of the calculation. ## What to do now 1. Confirm the current value for the year. 2. Have each person's daily salary at hand. 3. Check the days and hours worked in your record. 4. Do the math and keep it. 5. Validate it with your accountant. ## Related terms **[Overtime: what it is](https://sicheca.com/en/blog/tiempo-extraordinario).** Overtime is the hours worked above the ordinary workday. **[What is the payroll CFDI](https://sicheca.com/en/blog/cfdi-de-nomina).** The payroll CFDI is the payment receipt stamped with the SAT that the company issues for each salary payment. **[Vacation premium: how much it is and when it is paid](https://sicheca.com/en/blog/prima-vacacional).** The vacation premium is an additional payment of at least 25% on the salary for the vacation days. ## Frequently asked questions ### Did the 2026 reform change it? No. The text was updated, but the percentage is still 25%. ### 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. ### Where does the data come from? From the Federal Labor Law and from the official values published by INEGI and the National Minimum Wage Commission. ### Do these values change every year? Yes. The UMA is updated every February 1 and the minimum wage every January 1.
