Residents of Québec's Border Regions
Residents of Québec's border regions have the same requirement to file an income tax return as non-border residents. In other words, you are required to file a return even if you live near the border with another province or a US state.
Since the regular April 30 filing deadline falls on a Sunday this year, you have until May 1 to file your 2016 income tax return and pay any income tax you may owe.
If you or your spouse earned business income, you have until June 15 to file your return. Any balance owing, however, must be paid by May 1.
