The new Decree 158/2025/ND-CP, effective from July 1, 2025, stipulates that the basis for compulsory social insurance contributions includes not only the basic salary but also allowances and regular supplements stipulated in the labor contract.
This new regulation aims to ensure that social insurance contributions and benefits accurately reflect the income of employees, while also protecting their full entitlements related to maternity, retirement, sick leave, and long-term benefits.
Low Basic Salary in the Contract Puts Employees at a Disadvantage
Under the previous Decree 115/2015/ND-CP, the basis for social insurance contributions only included the basic salary and some allowances, while most other supplements such as bonuses, sales commissions, and overtime pay were not taken into account. This resulted in significant reductions in maternity and retirement benefits.
In reality, many women working in retail, services, beauty, and education sectors receive a low basic salary, with most of their income coming from fixed allowances and living support. For example, Ms. Thuong, a sales employee at a cosmetics store in Quang Ninh, earns a monthly income of 10 million VND, but her labor contract only states a basic salary of 5 million VND. The remaining amount comprises responsibility allowances, transportation allowances, and sales commissions. According to the old regulations, her social insurance contributions were calculated based on the basic salary of 5 million VND, resulting in a significant loss of benefits during her maternity leave.
With the new Decree 158/2025/ND-CP, if the allowances and supplements are regularly paid and clearly stipulated in the contract, Ms. Thuong’s social insurance contributions will be based on a more realistic income, ensuring higher benefits during maternity or retirement.

Recommendations for Female Employees
1. Proactively review the contents of your labor contract, especially the income components that are stable and regular, to ensure that the basis for social insurance contributions accurately reflects your total actual income.
2. Communicate specifically with the accounting or human resources department to understand the current basis for social insurance contributions and verify if the fixed allowances have been fully included.
3. For employees receiving their salary through bank transfers, carefully compare the monthly salary details with the labor contract. In case of unreasonable discrepancies between the social insurance contribution wage and actual income, employees can request adjustments to protect their long-term benefits, especially during maternity leave, sick leave, or retirement.
Decree 158/2025/ND-CP marks a step forward in transparency and fairness in social insurance contributions. For women, who are often at a disadvantage due to low wages and unclear contracts, understanding these new regulations is key to safeguarding their long-term welfare benefits.
