Goal and impact
The algorithm determines quickly and without error what amount will be deducted from the benefit. It uses data from the Basic Registration of Income (BRI) for this purpose. For residents, this means that settlement is automatic and they usually no longer need to submit pay slips.
Considerations
The algorithm helps the municipality process data. It allows employees to work faster and easier and fewer mistakes are made. It also ensures that everyone is treated fairly and the same.
The downside is that the algorithm does not recognise exceptions or errors in payroll. Therefore, employees always check the difficult situations.
In this way, the municipality ensures that the system remains reliable and that the rules of the Participation Act are followed.
Human intervention
The file automatically goes to a collaborator if:
- The algorithm has too little data.
- The situation is different from the fixed rules.
- The amount is more than €150.
- The income is not yet known.
The clerk then looks at the situation himself and can adjust the result.
Risk management
For predetermined risks, the file automatically goes to an employee. The latter looks at it himself. The municipality also uses a dashboard to see if there are any new risks, such as errors in payroll data.
Legal basis
The Work and Income Implementation Structure Act (Suwi) regulates that the municipality may use known data on work and income. For example, to determine how much benefit someone receives. The Once-only Questioning Act (WEU) ensures that residents do not have to send data again if the municipality or benefits agency already has it.

Data
- Type of data: BSN, net income, taxable wages, holiday pay reservations and welfare benefit information.
- Sources: the UWV's Polis administration, the Intelligence Bureau, and from our own benefit system Socrates.
- Personal data: only the data needed for the calculation. The municipality does not use personal characteristics, such as age or nationality.
Technical design
The algorithm follows fixed rules and does not learn on its own.
- Information that the algorithm uses: income data from the Intelligence Bureau, based on the UWV wage declaration chain, and benefit data from Socrates, the municipality's system.
- This is how it works: the wage data are checked according to fixed rules to make sure they are complete and correct. The algorithm then decides whether the income can be automatically offset against the benefit, or whether an employee should check it.
- What it results in: the income is automatically offset against the welfare benefit. Or an instruction is given to an employee.

- By applying the OIB-AIV process, we can process data on income of a resident receiving supplementary welfare benefits better and faster in the benefit administration. The effect is that the resident will no longer need to provide such income and related supporting documents, and any settlement or supplementary payment will be made faster and more unambiguouslyLast change on 31st of October 2025, at 13:29 (CET) | Publication Standard 1.0
