We formed a new company for a client in October 2013 which was to remain dormant for the foreseeable future. Our only communication with HMRC was to apply for agent authority for CT online as soon as HMRC had automatically generated a UTR and sent us the usual CT41G and 64-8. We received these within two weeks of formation. The CT41G clearly states you only need to contact HMRC within three months of the company becoming active. So we didn't contact them. On 15 January we received the CT610 showing the important dates, that is the first corporation tax periods.
I have just phoned HMRC to inform them that the company is dormant and they tell me me we must write in because they have been informed that the company is active. We know we haven't told them. We know the client hasn't told them. In fact the client wouldn't know as both copies of the CT610 came to us as the registered office.
I must assume that applying for agent authority online has triggered an "active" flag in their system. It is very irritating that you can tell HMRC many things online but you can't tell them they that have made a mistake and the company is not active. You have to write a letter! Has anyone else experienced this before?
