Officially abolishing the base salary of 2.34 million VND
From July 1, 2025, the Social Insurance Law (SI) 2024 (No. 41/2024/QH15) officially takes effect, replacing the SI Law 2014. One of the important changes is the replacement of the concept of the “base salary” with a “reference level” to calculate contribution rates and benefits of SI regimes. Especially, the reference level directly affects SI regimes such as retirement pensions, maternity allowances, funeral allowances, monthly survivor’s allowances, and convalescence allowances.
In particular, the application of the reference level instead of the base salary makes the allowances more flexible and suitable to the economic reality, ensuring the practical value of SI benefits. These policies not only encourage long-term SI participation among workers but also build a multi-layered welfare system, fairness, contributing to improving the quality of life and social stability in the context of Vietnam’s aging population.
According to Article 7 and Clause 13 of Article 141 of the 2024 SI Law, which took effect on May 1, 2025, the reference level is defined as follows:
– The reference level is the amount decided by the Government to calculate contribution rates and benefit levels of some SI regimes.
– The reference level is adjusted based on the consumer price index, economic growth, and the capacity of the state budget and the SI fund.
– When the base salary is not abolished, the reference level is equal to the base salary. At the time the base salary is abolished, the reference level shall not be lower than that base salary.
Currently, the base salary is 2,340,000 VND/month (according to Clause 2, Article 3 of Decree 73/2024/ND-CP).
Accordingly, from July 1, 2025, when the base salary is abolished and replaced by the reference level to calculate contribution rates and benefit levels of some social insurance regimes, the reference level shall not be lower than the base salary, i.e., 2,340,000 VND.
The switch to the reference level will affect some SI regimes. Especially from July 1, the SI Law 2024 will officially take effect, and the reference level will have a significant impact on many SI regimes that workers need to know.
