Antigua and Barbuda has signed an updated international agreement expanding the automatic exchange of financial account information between countries, advancing global efforts to combat tax evasion and strengthen fiscal transparency.

According to Antigua News Room, the Organisation for Economic Co-operation and Development (OECD) confirmed on June 25 that Antigua and Barbuda signed the addendum to the Multilateral Competent Authority Agreement on March 31, 2026. Kuwait had become the latest country to join the updated agreement just days earlier, on June 22.

The addendum revises the legal framework underpinning the Common Reporting Standard (CRS), the global system through which participating countries automatically exchange financial account information on an annual basis.

The OECD adopted the revised rules in 2022. They broaden the scope of financial information that member jurisdictions may share, helping tax authorities more effectively identify offshore tax evasion and adapt to evolving financial products and investment structures.

As reported by Antigua News Room, 76 jurisdictions had signed the updated agreement as of June 25, 2026. Antigua and Barbuda now joins that growing group of nations committed to implementing the expanded reporting framework.

The Common Reporting Standard requires financial institutions to collect information on accounts held by foreign tax residents. That data is then shared automatically with the relevant tax authorities in participating countries, subject to agreed safeguards.
