The digital platform for the A21 child benefit in Greece is set to open at the end of February 2026, aimed at assisting families to apply for or renew their child benefit applications. This initiative applies to both new recipients and those who had been receiving the benefit in 2025, who must resubmit their applications to ensure the uninterrupted continuation of payments. The platform will remain accessible until March 13, 2026, allowing sufficient time for families to complete the necessary processes.

The application process is entirely electronic and is conducted through the A21 application using personal Taxisnet codes. Guidelines specify that the responsibility for submission falls on the taxpayer who claims the dependent children on their tax declaration, or alternatively, on their spouse. Many fields in the application are pre-filled, leveraging data retrieved automatically from social security records and tax authorities, which streamlines the application process for families.

The child benefit amount is determined based on income criteria and varies with the number of dependent children. Applicants are encouraged to carefully verify the pre-filled information and fill in any required details that may not have been automatically populated. This targeted approach aims to ensure that eligible families receive the appropriate financial support they need during the specified time frame.
