B.C. accountant Chris Cowland spotted error in CRA tax filing deadline

You now have a little more time to file your taxes, all thanks to a Vancouver Island accountant.

The Canada Revenue Agency gave the wrong income tax deadline in a notification sent out to some taxpayers on Friday, saying the deadline had been extended to May 5 when it actually hadn't been. 

Accountant Chris Cowland, from Sidney, B.C., noticed the CRA's mistake on Monday and alerted Green Party leader Elizabeth May who passed it on to federal Revenue Minister Kerry-Lynne Findlay.

"And boom, CRA fixed it," Cowland told CBC. 

The CRA has now officially extended the deadline to file to May 5th...

Cowland says the wrong deadline could have cost his clients dearly. 

"Some of them can owe $10,000 ... $100,000 in tax. And if they left it until the [wrong] filing deadline, then 10 per cent penalty."

​But Cowland makes it clear he doesn't want any special attention for his actions.

"Oh God, I don't want to get my name out there cause they'll audit me. I don't want to be on the wrong side of the CRA."
