Thanks mcshop, the option to submit a final payroll isn't available in the standard version; instead, you can use HMRC's Basic PAYE Tools to complete this after running the final period QB. After this, you can export the payroll data and cancel the payroll subscription:

1. Go to the Gear icon.
2. Select Account and settings.
3. Go to the Billing & Subscription menu.
4. In the Payroll section, select Cancel.
5. Fill out the online cancellation form to complete the process.
