Hi so just finished my tax return and I have to pay Class 4 NIC for 2014-2015. But I have already paid Class 2 NIC this year. I didn't realise that Class 2 no longer applied to me as my profits were higher this year. Do I just apply for a refund of Class 2 separately? Can't download the form without filling in all my details and it also looks like the deadline is the same as the tax return - will I not get a refund if they don't receive this in time? Help!
