Or use your favorite software package, contact your accountant – anything just to not procrastinate. Sometimes you can get an extension for filing the return, but always need to pay on time to avoid penalties.
In general, for Ontario Canada, your return should be filed on or before April 30, 2015 this year. If you are self-employed and carry on a business, then your deadline to file is midnight on June 15, 2015, but you still need to pay any balance owing by April 30, 2015.
Avoid the CRA penalty and interest by making the next week or two, tax time and getting it done.
Well there is always spring to look forward to!
