Clients might want to get a head start on their 2017 taxes.

That’s because this year’s window to file taxes is the shortest in electronic filing history, notes H&R Block Canada in a release.

“This year, the Canada Revenue Agency (CRA) will open its e-filing the latest it has ever opened since its introduction in the early ’90s,” says the firm. “What was previously an 11-week time span has been reduced to nine weeks, with the deadline to obtain and sort financial documents still set for April 30, 2018.”

In the release, Lisa Gittens, an H&R Block senior tax professional, says, “We’re seeing the CRA open their online portal to accept returns happening slightly later each year, which puts added pressure on Canadians to get organized and file on time.”

E-filing opens Feb. 26, 2018.
