IMSS audit and social security assessment defense

Audits and review of employer obligations

We review IMSS requests and acts to establish the obligations, employees and periods covered. That scope allows us to organize payroll and social security information for analysis. Differences between internal records, filed notices and payments require a verifiable explanation, so the response does more than submit reports without showing their connection to the observation received from the authority during its examination.

The contribution base salary requires reviewing payment components and their treatment in the circumstances of the case. We work with payroll records and the responsible departments to identify the facts supporting the employer's position. If classification or the risk premium is questioned, we review the activity and background relied on by the Institute, alongside the company's records of its operations and workers.

During the examination, we track requests and submission receipts. We also review the authority's competence, reasoning and the scope of the acts issued. Maintaining an organized file helps answer further observations and assess later decisions without losing the relationship between employer data, explanations submitted and the authority's conclusions about the obligations and periods under review in the proceedings against the company.

Assessments, penalties and risk decisions

An IMSS decision must be analyzed by its components and the procedure behind it. We review contributions, additional charges, penalties and, where relevant, capitales constitutivos, the recovery of benefit costs claimed by the Institute. We identify the facts and calculations asserted, then separate disputed issues and the evidence supporting the defense, without assuming that all determinations can be challenged with the same argument.

We assess administrative or judicial remedies available for the act and the company's position. The strategy considers service, background records and the requirements governing each route. We also analyze collection effects and measures that may be needed while the dispute is resolved, distinguishing the merits of the case from steps intended to protect operations and address the continuing effects of the decision.

Human resources, payroll and accounting departments often hold complementary records of the same matter. We coordinate their review to avoid inconsistent responses and locate relevant evidence. Our assistance includes handling later requests and explaining the defense's status to the business, with a position grounded in its actual records and the scope of the challenged decision rather than assumptions about the employer's activity.
