Splitting a business is more likely to be accepted by HMRC if there is some commercial justification and logic for it, e.g. to reduce the work required of a business person nearing retirement age. The cost of the extra paperwork should not be underestimated. Also, the effects on other taxes should be considered. A division of a business may constitute, what is for income tax purposes, a cessation of the trade and the commencement of a new one, especially if the scale of activities falls considerably. The change may result in the loss or restriction of capital gains tax reliefs, such as roll-over and retirement relief, and also inheritance tax business property relief.
