What does the date April 30th mean to you?
If you've already filed your tax return, the answer is nothing.
If you haven't yet filed, the answer from Lisa Gittens of H&R Block is - it's an important deadline.
"Some people have started their returns, but they're waiting on a slip - or, they simply didn't have all of their paperwork together. So, now that they're getting reminders, they're trying to gather that paperwork together," says Gittens.
She says late filers are penalized a percentage of what is owed, so making the deadline can be expensive on any size income.
Gittens says if for example you owe $100, and you file after April 30th, there's an automatic 5% penalty applied to that balance. And for every 30 days that you are late paying the balance, there's an additional 1% interest charged to a maximum of 12%.
She says H&R Block's surveys indicate as many as 40% or more of Canadians are either last minute filers, or are late..or don't file at all.
