Information on account balances, sale proceeds from financial assets and income from certain insurance products is also part of the scope. The agreed rules are consistent with the OECD global standard of exchange, meaning that EU tax authorities will be able to use one single format for exchanging information both within and outside the Union. Member States have also committed to a proposal by the Commission to further improve the rules in 2019 by adding more information fields and to consider any other necessary adjustments. The OECD also recently agreed to improve its own exchange schema in 2019 in line with the EU's approach. Commission services will continue to work closely with Member States on the application of the Directive and with the OECD on the timely implementation of these improvements. In the interest of maintaining a single global standard, any further need to enhance the schema for information fields will be discussed at an early stage with the OECD.
