Hi there,
Recording your first Sales Tax payment in QuickBooks Online is exciting. I'd be happy to shed some light on how to do it.
Filing Sales Tax is a four part process. First, prepare your sales tax return in QuickBooks Online. Second, submit your return to the Canada Revenue Agency (CRA). Third, close your filing period in QuickBooks Online. Finally, record your payment to or refund from the CRA.
For a list of instructions and steps on how to complete each step, take a look at this Community article: https://quickbooks.intuit.com/community/Sales-tax/File-sales-tax/td-p/261654.
If you have any other questions about this process, please let me know.
Have a great day!
