I can't believe this hasn't come up before! (I did search) ...with the changes to the tax treatment on loans of BTL properties, many landlords have incorporated. They will soon find out that property investment companies can't file online with HMRC and needs specialist tax filing and iXBRL tagging software to file. There are plenty of options for practices, but almost none for anyone who already has their annual accounts but just needs them tagging and filing on their behalf. There are a few excel add-ins for tagging but they don't generally file the CT600. Does anyone have any suggestions for software to file with HMRC & CoHouse for property companies or even a bureau offering this service to property investment companies?
