TTM09260 - Capital Allowances: Balancing charges (P&M)
If a disposal event takes place, and the disposal value exceeds the amount remaining in the company’s own tonnage tax pool, the company may still be able to avoid a balancing charge by utilising expenditure from a fellow group company’s tonnage tax pool.
In such a case one member of a tonnage tax group may surrender all or part of the expenditure remaining in its tonnage tax pool to another company in the same group.
In order for such a surrender to take place, the two companies must have been members of the same group for at least a year at the time of the disposal potentially giving rise to the balancing charge.
