Prime Minister Justin Trudeau is nixing the idea of Quebecers filing one tax return that would be administered by the province.
Trudeau says it is not a decision to be made lightly and that it is not a priority for his government.
The Quebec legislature unanimously passed a motion two weeks ago seeking the change.
The debate was sparked when 89 per cent of delegates at a meeting of federal Conservatives in Quebec voted in favour of a resolution to combine federal and provincial tax returns into a single form collected and administered by Quebec
Quebec is the only province to have a tax department that is completely independent and distinct from the federal government's.
The province has collected the GST in Quebec for the federal government since the early 1990s.
