Liability to capital gains tax (CGT)

CGT is charged on net gains, i.e. total chargeable gains realised during a tax year after deducting total allowable losses realised in the year.

Companies are subject to corporation tax on chargeable gains calculated according to modified CGT rules.


Disposal of assets

CGT can only arise on the disposal of an asset. Normally this means sale, but it could also mean gift or compensation for loss or damage to an asset.

  • The value on which the gain (or loss) is based is normally the consideration received. However, on gifts and certain sales, the open market value is used instead.
  • No CGT is payable on death. The beneficiaries of a deceased person's estate are treated as if they had acquired the assets of the deceased at their market value on death.

Deductions

Certain costs are allowable in computing chargeable gains:

  • The acquisition cost or market value on 31 March 1982 (if the asset was acquired before that date).
  • Costs of acquiring and disposing of the asset.
  • Expenditure on enhancing the asset's value.
  • Indexation allowance (see Capital Gains Tax: Indexation allowance).

Losses

Losses brought forward from previous tax years can offset gains. For individual taxpayers, such losses do not reduce net gains below £8,800, so the annual exemption is not wasted. (See Corporation Tax: Capital gains by companies.)

Rate of tax

The first £8,800 of an individual's net gains realised during the tax year is free of CGT. The excess is taxed as if it were the top slice of income, at the rates that apply to savings income, namely 10% on the first £2,150, 20% on the next £31,150 and 40% on the balance.

Husbands and wives are subject to CGT separately, each with their own annual exemption and tax rates. Transfers between spouses living together are not liable to CGT.


Indexation allowance

The indexation allowance can reduce the chargeable gain for assets acquired before 1 April 1998, but it cannot increase a loss or turn a gain into a loss. The acquisition cost and enhancement expenditure (before April 1998) are revalued in line with indexation factors derived from increases in the RPI (retail prices index) between the date of expenditure and April 1998.

The indexation allowance is calculated by multiplying the allowable expenditure by the indexation factor for the month in which the expenditure was incurred or for March 1982 if later.

Example Allowable expenditure of £1,000 in June 1984. Indexation allowance: £1,000 x 0.823 = £823.


Identification of securities

Shares and securities disposed of are identified with acquisitions in the following order:

  • Same day acquisitions.
  • Acquisitions within the following 30 days (thereby rendering 'bed and breakfasting' ineffective) but not any acquisitions after a person has become non-resident.
  • Previous acquisitions after 5 April 1998, taking the most recent acquisition first.
  • Any share in the 'pool' at 5 April 1998.
  • Any shares held on 5 April 1982.
  • Any shares acquired before 6 April 1965.

Taper relief

Taper relief reduces a chargeable gain by reference to how long the asset has been held. It is applied to net gains after any indexation allowance. Losses are deducted so as to minimise the total chargeable gain. Different rates of taper relief apply to business assets and non-business assets. Business assets include:

  • Assets used in an unincorporated business. The owner of the asset need not be involved in the business.
  • All shareholdings in unlisted trading companies, including AIM companies.
  • Any shareholding of 5% or more in a quoted trading company and any shareholding in such a company held by any employee or director.
  • Employee holdings of up to 10% in non-trading companies.
  • Assets used in the company's trade where the shares are business assets in relation to the individual.

*Non-business assets acquired before 17 March 1998 qualify for an extra year's worth of taper relief.


 

 

 

 


Example A non-business asset acquired for £10,000 in May 1985 is sold for £45,000 net of expenses in June 2006. The asset qualifies for 9 years' taper relief (8 years to 6 April 2006 plus bonus year).
