The alleged offence stems from the discovery of Bt10 billion in overseas accounts that were not revealed in statements made while in office.
Commission member Wichai Wiwitsevi said yesterday information provided by British authorities would be considered. They told the commission Thaksin had more than Bt10 billion in United Kingdom and Swiss banks.
A check revealed this money was not declared on Thaksin's assets declarations made while prime minister, Wichai said.
"If it is true Thaksin has these accounts abroad, then he committed graft by submitting false assets declarations to the commission," he said.
The Counter Corruption Act says political-office holders must submit declarations of assets held both at home and abroad, he added.
Commissioner Somluck Chadkra-buanphol said yesterday that the agency would ask the Assets Examination Committee to adopt the case because it has the power to probe the allegations.
"It is quite complex and difficult to check assets of politicians overseas. The commission has never checked this. We have to seek the Foreign Ministry's cooperation. Some banks have a policy of keeping client information confidential," she said.
