Hi Sandy I,
Thanks for reaching out to us here. QuickBooks Online Payroll automatically calculates the associated taxes, in keeping with government guidelines. It also ensures accuracy on the associated payroll forms.
Box 24 displays the total amount of insurable earnings. This is the amount you used to calculate your employee's EI premiums reported using box 18, up to the maximum insurable earnings for the year, as outlined on the CRA website. However, it's important to review the payroll set up, to ensure accurate calculations.
Your time is valuable, and for this reason I feel the best course of action would be to speak with a QuickBooks Online Payroll specialist. They will be able to work with you in real time, and , and ensure your T4 sliops are accurate without delay!
If you have any other questions, feel free to reach out. We would be glad to help!
