Individuals must file their income tax returns for the tax year on the last day of April.
If the due date falls on a public holiday or weekend, you have until the next business day to file your return. For example, if the due date is Sunday, April 30, your return is due on Monday, May 1. Individual tax returns for the 2018 taxation year are due to the CRA by April 30th, 2019.
Returns filed and paid (unless they are credit returns) by April 30th, 2019 will not incur interest or penalties.
Self-employed individuals and their spouses or common-law partners have until June 17th, 2019 to file their tax returns. However, any balance owed must still be paid by April 30th. If you have self-employment income, consider preparing your tax return well before April 30 to calculate if you have a balance owed. This will help you avoid late-payment penalties.
Credit returns, or returns with refunds, which are filed late will not incur a penalty because the CRA bases the penalty on the balance owing, however chronically filing late tax returns can be a problem if there ever is a balance owing, and you want to make an application for Taxpayer Relief. The CRA might decide to deny your request due to your pattern of late filing.
As well, should you owe money and file late, the CRA can double the penalty, so keep that in mind as you file your return on time this year using any of the TurboTax Self-Employed options.
