Thank you for responding. I recall Intuit historically released the tax tables for the new year in mid December however, I don't recall an update that specifically allows for filing the T4 forms to CRA. 

1. Is there a separate update for this?

2. When is it typically released?

3. In some cases T4 slips must be filed within 30 days after the last payroll - how would this be done throughout the year if T4s can only be processed by QuickBooks in January of each year?

Thank you in advance for your responses.
