Welcome, @Izzy74 and thank you for coming to the QuickBooks Community for assistance. I have some insight on cancelling your payroll subscription to pass along.

During the cancellation process, you will be asked if you'd like your tax payments and filings to continue to the end of the year. This will ensure that payment gets processed.

For more information on canceling Payroll, click here.

If you have any other questions, please don't hesitate to reach out. I'll be here to help.
