Hello, @TL23.
I appreciate you posting here in the Community and sharing the step you've done to fix this. I'm here to help get rid of the error you're getting when updating payroll in QuickBooks Desktop (QBDT).
The error 15276 occurs when one of the files to be updated is in use and cannot be replaced. Since you already downloaded the QuickBooks Tool Hub and run the Quick Fix and the issue persists, let's perform a clean install of QuickBooks in Selective Startup as mentioned by @Fiat Lux - ASIA.
Before we proceed, make sure you have everything you need for the process.
- Create a backup of your company file.
- Keep a copy of your QuickBooks Desktop product and license info.
Once done, you can refer to this article and proceed to Steps 2 - 4 for the detailed steps on how to perform the clean install: Install or uninstall QuickBooks in Selective startup.
After that, try to update your payroll by downloading the latest tax table again to double-check. You may check out this article for further guidance: Get the latest payroll tax table update.
