The official deadline for submitting P11ds is this Saturday 6 July 2019. You will need to submit one if you are an employer who has given any non-cash benefits or benefits in kind to your employees, or if you have reimbursed any of your employees’ expenses. The P11d form uses brown boxes for benefits in kind, and blue boxes for reimbursed expenses. It is a complicated form which may be best left to an accountant! There is every possibility of putting something in the wrong box and you need to look carefully at the result of what you are doing rather than dumbly working through whatever software you might be using!
Let’s say you are a bit late, and submit it on July 14th. Nothing will happen. You have until July 19th, a little bit of grace, to make the submission. If you submit it late after that, then you will be fined at the rate of £100 per month for every 50 employees or part thereof that you are late. However, the count of months is backdated to July 7th, so if you file on August 12th, you will be fined £200 per batch of employees.
It is just as well we say 6 July as the deadline, because when employers are late they tend to be very late. However, there is a bit of leeway if you are slightly late.
