TTM09330 - Capital allowances: Exit from tonnage tax (P&M)

Qualifying expenditure: Long-life assets

Long-life assets are those which may reasonably be expected to have a useful economic life of at least 25 years when new.  Ships were excluded from the long-life asset legislation until 31 December 2010.

Expenditure on long-life assets is written down in the special rate pool.  See CA23700 onwards.  From 1 April 2018 the rate is 6 per cent on reducing balance basis.

The qualifying expenditure that should go into a company’s special rate pool in respect of long-life items of machinery or plant is a percentage of the original cost of the asset.

The percentage varies according to length of time that the company owned the asset before leaving the tonnage tax regime, as follows:

Length of period of ownership to date of exit	Percentage of original cost to go into capital allowance pool
Less than or equal to 1 year	94
From 1 year and one day to 2 years	88
From 2 years and one day to 3 years	83
From 3 years and one day to 4 years	78
From 4 years and one day to 5 years	73
From 5 years and one day to 6 years	69
From 6 years and one day to 7 years	65
From 7 years and one day to 8 years	61
From 8 years and one day to 9 years	57
From 9 years and one day to 10 years	54
From 10 years and one day to 11 years	51
From 11 years and one day to 13 years	47
From 13 years and one day to 16 years	40
From 16 years and one day to 19 years	33
From 19 years and one day to 22 years	27
From 22 years and one day to 25 years	23
From 25 years and one day to 30 years	18
From 30 years and one day to 35 years	13
From 35 years and one day to 40 years	10
From 40 years and one day to 45 years	7
From 45 years and one day to 50 years	5
