The new framework, to be presented before a meeting of G-20 finance ministers in September, would mark a significant forward movement from the current practice of information exchange mostly on the basis of requests and only in the cases of suspected tax evasion or other financial crimes.
The new global standard, which would be common for all countries, would facilitate a "systematic and periodic transmission of bulk taxpayer information by the source country of income to the country of residence of the taxpayer concerning various categories of income or asset information".
To enable automatic exchange of information on an annual basis, the financial institutions, including banks, brokers and fund houses, would have to mandatorily collect necessary details from their clients and submit the same to their respective regulators.
Paris-based Organisation for Economic Cooperation and Development (OECD) said that such an automatic exchange of information would "help detect cases of non-compliance even where tax administrations have had no previous indications of non-compliance", besides providing timely information on non-compliance where tax has been evaded.
This assumes significance in case of India, as it has been facing difficulties in getting information on cases of suspected tax evasion from other countries, specially Switzerland, which has been maintaining that such details can not be shared without specific proof of financial irregularities by the concerned Indian client of Swiss banks.
An initial framework was released by OECD in this regard earlier this year and India became one of the 'early adopters' of this global convention.
Later, Switzerland also committed to abide by this framework, while a few more countries have now expressed their interest in adopting the same and these include Mauritius -- another country with which India has been working on a revised bilateral treaty due to concerns of money laundering.
Those having already committed to follow this global protocol include the US, the UK, Germany, European Union, Japan, Singapore, China, as also financial centres like Luxembourg, British Virgin Islands, Cayman Islands, Gibraltar, Cyprus, Bermuda, Isle of Man, Greece and Liechtenstein.
However, such an exchange of information would also have a confidentiality clause and safeguards, while countries would need to pass domestic laws as per their respective legal jurisdictions to enable such a cooperation.
The standard, once implemented, would allow governments to obtain detailed account information from their financial institutions and exchange the same automatically with other jurisdictions on an annual basis.
OECD Secretary-General Angel Gurria said the standard "moves us closer to a world in which tax cheats have nowhere left to hide".
All information exchanged is subject to the confidentiality rules and other safeguards, including provisions that limit the use of that particular information.
"Each competent authority will notify the other competent authority immediately regarding any breach of confidentiality or failure of safeguards and any sanctions and remedial actions consequently imposed," the grouping said.
The standard has two components -- Competent Authority Agreement (CAA) and Common Reporting Standard (CRS).
According to OECD, automatic exchange may help educate taxpayers in their reporting obligations, increase tax revenues and thus "lead to fairness -- ensuring that all taxpayers pay their fair share of tax in the right place at the right time".
