How do I run a P11 report in Advanced Payroll?

Hello Kate-sarsby, 

Welcome to the Community page, 

So there is no P11 report in advanced payroll there is only a P11D report. If you have a look at this article tells you more  P11D won't populate for this tax year. You set up the benfits now and they will be used for the next year. So this is currently working correctly it wont show till next tax year this article here also tells you more the P11 D (b) is to claim back the NI for any payrolling benefits they have registered with at HMRC however they also have to submit the P11D but that option isn't implemented yet
