Hi there, 

It's our top priority to ensure that QuickBooks is recording the proper taxes for you and your employees. Don't worry, I'll help clear this up for you. 

According to the Government of Canada website (https://bit.ly/2gPSwlo), "every person over the age of 18 who works in Canada outside of Quebec and earns more than a minimum amount ($3,500 per year) must contribute to the Canada Pension Plan (CPP)."

If your employee earned less than $3,500 during 2018, they aren't obligated to contribute to the CPP. That's why QuickBooks hasn't deducted it from their pay. 

If you have any other questions, please don't hesitate to reach back out. 

Cheers!
