Do annual tax base for federal & provincial taxes for payroll change in a new year or do they need to be done annually?

Hi there, 

You've come to the right place for assistance. I'll be happy to share info about taxes in QuickBooks.

If you're referring to the tax tables, the good thing is that QuickBooks Online Online automatically updates the tables annually. You won't have to worry about manually updating anything regarding the tax tables. 

Let me know if this answers your question. I'll be one message away in case you need further assistance. :)
