HSBC created 2,300 offshore companies, Credit Suisse has 1,105 and UBS, has 1,100, while France's Societe Generale has 979, according to the latest revelations from the vast leak of documents dubbed the Panama Papers.
Le Monde reported that 365 banks across the world had used the services of Mossack Fonseca, the firm at the centre of the allegations.
Other major banks mentioned in the report include Germany's Deutsche Bank and Nordea, which does business in Nordic and Baltic countries.
The banks cited by Le Monde rejected any wrongdoing.
The CEO of Credit Suisse, Tidjane Thiam, said Tuesday his bank would endorse only "legitimate" offshore arrangements.
"We only accept offshore structures, vehicles, if they serve legitimate purposes," Thiam said, speaking in Hong Kong.
"Clearly, tax avoidance is not one of those," he added.
"We insist on knowing who is the beneficial owner. If it's not revealed, we will not engage in business with that entity," he added.
HSBC meanwhile said: "We work closely with the authorities to fight financial crime and implement sanctions."
A UBS spokesman told AFP that the bank "conducts its business in full accordance with the applicable regulations".
"The bank has no interest in funds which are not in line with fiscal rules or which come from illegal activity," he added.
The trove of Panama Papers documents was anonymously leaked to German daily Sueddeutsche Zeitung and shared with more than 100 media groups by the International Consortium of Investigative Journalists (ICIJ). More revelations are expected over the coming weeks.
