Information for Self-Employed Persons and Members of a Partnership
If you are a self-employed person or a member of a partnership, make sure you read the information specific to your situation before filing your income tax return.
The deadline for filing the personal income tax return is April 30. However, since you operate a business or are a member of a partnership, you (and your spouse) have until June 15 to file the return.
Note, however, that interest will be charged as of May 1 on any balance of income tax.
