​Automatic Exchange of Information (AEOI) and Common Reporting Standard (CRS)


AEOI is a process for exchange of information which requires a country to obtain financial information (such as depository account, custodial account and equity interest) from their financial institutions and exchange that financial information automatically on annual basis to treaty partners. The objective of AEOI is to detect and deter any tax evasion by taxpayers through the use of offshore bank accounts.

Common Reporting Standard (CRS) is an internationally agreed standard for the automatic exchange of financial account information between jurisdictions for tax purposes developed by Organisation for Economic Cooperation and Development (OECD). The CRS sets out the rules and procedures for AEOI and the types of reportable person, reportable account and financial information required to be reported by the financial institutions. The CRS also details out the financial account information to be exchanged, the financial institutions required to report, the different  types of accounts and taxpayers covered, as well as the customer due diligence procedures to be followed​ by the abovementioned financial institutions. More than 100 jurisdictions have endorsed CRS and have committed to start implementation of AEOI in either 2017 or 2018.

Brunei Darussalam committed to implement CRS AEOI starting 2018 onwards. Financial institutions in Brunei Darussalam are required to collect and report to the Collector of Income Tax Act as the Competent Authority the reportable financial account information starting from 1 January 2017. Financial institutions are required to collect information from 1st January to 31st December every year and report it (including nil returns if applicable) to the Competent Authority in the subsequent years no later than 30th June every year.
