Can't add Company CarI can't seem to add a company car to my personal tax. I've tried multiple times and i keep getting the following: Sorry You can’t use this service as more details about your work are needed. Please contact HM Revenue and Customs (HMRC). Having tried 4 times to contact via the income tax number, i go through the spiel and then get cut off. I just want to talk to someone! I've sat with my employer and they can't see anywhere on their gateway account where they can add a company car for me. Any ideas?
