QuickBooks Error PS036 typically occurs when there is an issue with your payroll subscription or company file, leading to disruptions in payroll processing. To resolve this, follow these steps:

1. Verify Payroll Subscription Status:
   Ensure that your QuickBooks payroll subscription is active and up-to-date. Log into your QuickBooks account and confirm that your subscription has not expired. If expired, renew it to continue using payroll features.

4. Check Company File for Damage:
   A damaged company file can also lead to Error PS036. Run the QuickBooks File Doctor tool to check and repair any issues within your company file.

5. Run QuickBooks as Administrator:
   Open QuickBooks Desktop as an administrator by right-clicking on the QuickBooks icon and selecting Run as Administrator. This ensures that QuickBooks has the necessary permissions to access files and processes.
