Will QBO be adding the new T4 box 45 soon?

Hello rrtokai,

Thanks for reaching out to us here.  QuickBooks Online Payroll automatically updates the associated forms in keeping with government guidelines.  Rest assured that the required elements for the new Dental benefit associated with Box 45, will be applied to the T4 soon, before the end of November.

If you have any other questions, feel free to reach back out.  We would be glad to help!
