According to Banze, INSS collected around 480 million meticais during the first half of 2026, an amount that remains well below the total debt owed by companies.
The official said the institution is prioritising an educational approach towards contributors, with the aim of preventing non-compliance and avoiding a further increase in the number of companies falling into irregular status.
Banze said awareness efforts should be combined with stronger inspection mechanisms, particularly in cases where employers have already failed to meet their contribution obligations.
According to the INSS delegate, companies that remain in breach of their obligations are subject to sanctions under the social security framework.
The figures come as INSS seeks to strengthen mechanisms for monitoring and controlling contributions, amid concerns related to fraud, corruption and the possible diversion of institutional resources.
In September, Labour Minister Ivete Alane called for stronger internal control mechanisms during the National Social Security Meeting held in Tete Province.
At the meeting, the minister highlighted the need to improve audits, risk management, transaction traceability and the security of INSS information systems.
Authorities believe that strengthening these mechanisms will be essential to improve compliance with contribution obligations and recover part of the outstanding debt owed to the social security system.
