Common mistakes
- Inventing a “class I” rate (0.54355 / 0.50055) without the SUA certificate.
- Mixing it up with the worker IMSS quota (this branch is employer-only).
- Applying the premium to uncapped wages above 25 UMA.
No. Occupational risk is an employer contribution. The worker quota has no risk branch.
No. It is an educational default. Paste the premium from your SUA certificate.
