UBS will be charged with illegal banking practices and dissimulating tax fraud, the sources said, adding UBS's French subsidiary will also go on trial for complicity.
Five UBS top managers are also facing trial, including Raoul Weil, the former third-in-command at UBS.
France opened a probe into UBS after former employees blew the whistle over the bank's alleged system of setting up dual accounts to hide the movement of capital into Switzerland between 2004 and 2012.
The bank's employees allegedly approached French clients, from wealthy businessmen to sports stars, during receptions, golf tournaments or concerts to convince them to hide their money in Switzerland.
In June last year, French prosecutors recommended that UBS face trial for "aggravated laundering of tax fraud proceeds" while its French branch be judged for complicity in these crimes.
The move followed failed negotiations over a plea bargain.
"Those negotiations failed in particular because prosecutors and the bank could not agree on the sum that the bank would have to pay," said one source close to the case.
UBS has always denied any wrongdoing, saying there was no proof for its implication in any such alleged scheme.
On Monday, it said it rejected both "the allegations and the nature of the charges brought", a UBS spokesman told AFP in Paris.
On the Zurich stock exchange, UBS shares dropped 1.2 percent in response to the news.
