Company change to limited one & I have to transfer all staff to new paye ref. Any ideas how I should do this - I saw somewhere that everyone has to be put as leavers?

Thanks for reaching out to the Community, hill-family.

You can mark everyone as leavers, then run their final payroll and send an FPS. After that, you can give them a P45. The steps to do this may differ depending on the payroll subscription you're using.

For QuickBooks Online (QBO) Standard Payroll, here's how:

1. Go to the Employees menu to get to the Employees page.
2. Click a name to open their profile, then pick Mark as leaver in the Actions drop-down.
3. Enter the necessary information.
4. Select Done to dismiss the note that their P45 will be available at the end of the final payroll.

On the other hand, if you're using PaySuite, please refer to this article for further guidance: How to make an employee a leaver in PaySuite.

Let me know in the comment if you have any other issues or concerns. I'm more than happy to assist. Have a wonderful weekend!
