The first mandatory reporting of securities and crypto asset account balances will cover 31 December 2025 and 30 June 2026.

Belgium’s government has published amendments regarding the annual securities account tax on 17 September 2024, which were submitted to parliament on 24 September 2024.

Under the amendments, Belgian tax inspectors are now granted access to the central database of the Belgian National Bank, which contains relevant financial data on individuals and companies. This access is limited to a maximum of one year after the statute of limitations for tax claims has expired.

The authorisation covers securities accounts, which hold financial instruments as defined under MiFID 2, and crypto asset accounts, which include digital assets as outlined in the EU regulation on anti-money laundering and terrorist financing.

Reporting requirements include details about the opening or closing of securities or crypto assets accounts, any changes in authorised representatives, and periodic account balances. Specific information, such as account numbers, dates, and the identities of account holders or co-holders, must also be disclosed.

The first mandatory reporting of balances for both securities and crypto asset accounts will cover the amounts held as of 31 December 2025  and 30 June 2026.
