I am using Quickbooks payroll. I created two pay cheques, which are not affecting federal tax of Trial balance. Can someone help me with this?

Hi sh2295,

Welcome back to Community!  It's great to hear that you're paying your employees through QuickBooks Online Payroll.  It's important to understand why the federal tax is not affecting the trial balance.  I'd be happy to assist!

There's a few things to review in order to determine why federal tax has not been applied when running payroll.  If the gross wages of the employees last payroll are too low, or the total annual salary exceeds the limit, the tax would not apply.  I'd also recommend reviewing the TD1 information to ensure the date of birth is accurate.  Although EI should be calculated, the CPP depends on an employee's age.  Here's an Employer's Guide for Payroll Deductions and Remittances for your reference.  I suggest having a look at the employee pay cheque to see if the calculations were applied by going to Payroll > Employees > Pay Cheque List and then click on the employee to open the details.
