The Vacation Premium Calculation Error in Aspel NOI
Aspel NOI is one of Mexico’s most widely used payroll systems. A frequent problem users face is incorrect vacation premium and vacation days calculation, especially after the Federal Labor Law (LFT) reform effective January 2023.
Prerequisites
- Aspel NOI version 10.0 or higher.
- Administrator access to the system.
- Updated seniority table with the 2023 LFT reform values.
Step-by-Step Solution
1. Update the Seniority Table
Navigate to: Configuration → Tables → Seniority (Vacations)
| Years of service | Vacation days (LFT 2023) |
|---|---|
| 1 | 12 |
| 2 | 14 |
| 3 | 16 |
| 4 | 18 |
| 5 | 20 |
| 6-7 | 22 |
| 8-9 | 24 |
| 10-11 | 26 |
The minimum vacation premium is 25% of the salary for vacation days (Art. 80 LFT).
2. Verify the Employee Start Date
- Access: Employee Catalog.
- Verify the “Start Date” field is correct.
3. Verify the Vacation Premium Concept
- Access: Payroll Concepts Catalog.
- Locate “Vacation Premium” and verify it is active with the correct formula.
4. Recalculate the Payroll
Navigate to: Processes → Payroll Calculation and recalculate the affected period.
Prevention
- Apply Aspel NOI updates immediately when available.
- Back up the database before modifying configuration tables.
- Verify the seniority table at the beginning of each fiscal year.
