P11d and registering for payrolling

If I register for payrolling for my employees BIKs, does this mean I can no longer send a P11d? I understand that I don't do both, my question arises because I have recently registered with HMRC to do payrolling from the next tax year but have discovered that my payroll software needs to be upgraded to cover payrolling benefits. It is not an easy upgrade and involves completely starting from scratch on the new upgraded payroll software, so I am currently in two minds whether to just continue with P11d annually. If I leave my payrolling registration active, does it matter if I end up not payrolling the benefits but continue with P11d? I didn't want to cancel the registration if I ended up wanting to upgrade my software after all as I know you must register before the start of the tax year.

Hi ElectricianInOxfordshire,
If you wish to deregister from payrolling benefits, you would need to do this, online, before the start of the tax year.
If the tax year has started when you change your mind, you must wait until the end of the tax year before you can stop payrolling.
Please see guidance here:
Payrolling: tax employees' benefits and expenses through your payroll
Thank you. 

What happens if I am registered for payrolling but then do not payroll any benefits?

Hi ElectricianInOxfordshire, Once you have registered to payroll you must do this unless you amend it to remove these benefits. Thank you

Ok, and if I have say 6 employees and only 5 are receiving the benefit (health insurance in this case), can I do payrolling for the 5 but exclude the employee who is not receiving the benefit?

Hi,
If they are not receiving the benefit you wouldn't payroll for them.
Thank you.
 

Hi Starting payrolling benefits from April - for cars a P46 was previously sent prior to payrolling, does any information need to be shown in April payroll or as information has previously been submitted only include when change of car?

Hi,

If you have registered to payroll benefits for 2024 to 2025, then you will need to report the car benefit via payroll from the first payday. In addition to the benefit charge you will also need to provide the car details.

Thank you.
