Contributions online is a real-time online system enabling workers to access data on the contributions made by their employer to all branches of social security, through a single and intuitive interface and in a simple and easily accessible manner.

Workers can compare the information entered by their employers with their own statements. Supervision is thus ensured through worker-employer comparisons, improving risk perception, preventing under-declarations and omissions that will detract from the workers' future benefits and even their health and employment accident coverage.

Various types of queries of the Federal Administration of Public Resources (Administración Federal de Ingresos Públicos (AFIP)) have recently been added to the "free" service, whereby users send a text message (SMS) to the number 2347.

By sending the single word contributions, the employee can access the latest contribution paid by the employer (for employed workers or with certain employers) and the last contribution paid by self-employed workers.
