Since personnel expenses represent one of the largest cash outflows for medium and large companies, it is common for companies to seek alternatives to reduce the burden of payroll taxes and social security contributions.
However, there are still proposals on the market that suggest using productivity bonuses as the primary means of compensating employees, with the promise that they will immediately reduce the company’s costs. An analysis from a risk management perspective demonstrates why this practice, if poorly structured, jeopardizes the business’s financial and legal stability.
Common Practices: The Myth of the IMSS-Exempt Bonus
A very common practice in the business world is to register an employee with a low Base Contribution Wage (SBC) and supplement the rest of their monthly pay with items called productivity bonuses or incentives, under the assumption that these amounts are not included in the calculation of social security contributions.
However, the authorities have already taken a very clear stance. The Mexican Social Security Institute (IMSS) published Agreement ACDO.AS2.HCT.260623/160.P.DIR in the Official Gazette of the Federation, which establishes an official guideline stating that payments made in the form of productivity bonuses or production incentives are included in the Base Contribution Wage.
This criterion is based on Article 27 of the Social Security Law, which stipulates that wages consist of everything paid to the employee in exchange for their work (whether in the form of cash payments, bonuses, commissions, or benefits). If these bonuses are used solely to disguise the regular salary, the IMSS has full authority to retroactively collect unpaid contributions, along with interest, surcharges, and fines that can be very costly for the organization.
SAT Audits and Article 90 of the Income Tax Law
The risk is not limited to Social Security; the Tax Administration Service (SAT) also closely monitors the withholding of income tax (ISR) from wages.
In accordance with Article 90 of the Income Tax Law, and in accordance with the provisions of the Federal Labor Law, any income that increases a worker’s net worth as a result of their employment is subject to tax, unless the law explicitly states otherwise.
If a company issues productivity bonuses on a fixed and consistent basis without withholding the corresponding taxes, the tax authority may deny the deductibility of the entire payroll and hold the company directly liable for the tax debt.
A temporary savings on payroll will never justify a permanent risk to the company's assets.
The Dangers of Data Sharing Over the Internet (Electronic Monitoring)
Today, authorities conduct automated audits by cross-checking large volumes of data from payroll receipts (CFDI) and the tax returns that companies file each month.
If the regulatory authority’s systems detect that a company reports that nearly all of its employees earn the minimum wage, but at the same time it is a business with high sales and where “productivity bonuses” constitute the largest portion of employees’ fixed, recurring pay, a red alert is automatically triggered. This inconsistency in the data causes the company itself to come under scrutiny for an in-depth review, without the need for an auditor to visit in person.
How should a company properly structure its payments?
Productivity bonuses are an excellent tool for motivating teams and making the company more competitive, but they must always be designed and paid in accordance with the law, recognizing that they are part of the employee’s total compensation.
True payroll efficiency isn't achieved by changing names on pay stubs or making up line items on the payroll system just to see what happens. The solution lies in implementing a transparent and well-structured payroll tax planning strategy that takes full advantage of the actual benefits already provided by the law.
Good legal advice helps avoid problems with the authorities, provides certainty to partners, and protects the talent that drives the business's growth.
