Business Error 3001 Error 7974 when submitting P11d with P46 car forms

This is not an Iris issue but is happening for the following reason:- If the car relinquished date or the car acquisition date is before 5th April 2016 then it is not within the current year. Only cars relinquished or acquired with the date of after 6th April 2016 can be attached. The HMRC are aware that the information on their web site is misleading but unfortunately they have advised that the current tax year is from 6th April 2016 and therefore the P46 car forms should have been lodged with them before 5th April 2016. Clients are advised that they will need to remove the tick from the box that says P46 car forms attached. Regenerate the P11d’s and they will then be accepted. If you wish to send in the P46 car forms then you will need to send them via post and we would suggest that you download the ‘unable to file form’ from the hmrc web site and fill in the relevant information and attach the form to the P46 car forms.
