Not sure on something?
22nd July 2016 Deadline
Following completion of the P11Ds for the tax year ended 5th April 2016 any Class 1A NICs must reach HMRC by the 22nd July 2016. This is for online payments only and should be made in the same way as usual PAYE payments are made using the same Accounts Office Reference. If you need to quote an addition 4 digit reference for the payment then this will be 1613.
