Revenue Quebec estimates that Léger-Villandré owes it more than $307,000, a conclusion reached after looking into her income tax returns between 2008 and 2012.
She allegedly made false declarations on her returns for her snow-removal and excavation business, notably that it suffered major losses between those years. She also earned a salary as Hudson city manager during that period.
Léger-Villandré was city manager between 1997 and 2013.
Revenue Quebec says it moved in to seize Léger-Villandré's assets after discovering she had allegedly been trying to liquidate some of them.
In a separate matter, the former Hudson city manager is facing 19 charges connected to a series of events that took place between 1997 and 2013.
Léger-Villandré is accused of fraudulently depositing, over 17 years, more than $1.1 million in municipal cheques into a personal bank account.
Revenue Quebec says those charges are completely unrelated to the issue of unpaid income taxes.
