FATCA and/or CRS self-certification

On this page you can find links to the various self-certification forms and glossaries. Make sure that you complete the self-certification form(s) that ING has requested you to complete.

The U.S. Foreign Account Tax Compliance Act (FATCA) and the OECD Common Reporting Standard (CRS) require financial institutions such as ING Bank N.V. and its affiliates acting for themselves and for all branches and subsidiaries of ING N.V. (hereinafter: ING) to collect and report tax related information about its clients (Account Holders) and their accounts held. If the Account Holder or any of its Controlling Persons have a tax residence outside the country where the account is held or is a U.S. Person, ING may be legally obligated to pass on the information provided in this form, as well as other financial information with respect to any Financial Account held with our institution to the tax authorities, for transmission to the relevant competent foreign tax authorities pursuant to intergovernmental/multilateral agreements. Please visit www.irs.gov/fatca and www.oecd.org for more information.


Please follow the instructions on the self-certification form carefully, as incorrect or incomplete information may result in the data on the self-certification forms and relevant information on your accounts being incorrectly reported to tax authorities.
