With quoted shares and securities (and also unit trusts and OEICs), there is more scope for CGT tax planning than there is with most other chargeable assets. This is because it is easy to sell or gift the exact number of shares required to arrive at a particular chargeable gain or capital loss. Other assets, such as unquoted shares, are more difficult to sell and with assets such as land and property it is not generally practical to dispose of just part of the asset in order to achieve a gain equivalent to, say, the annual exempt amount.

There are several million shareholders in the UK and many of these will have built up portfolios of sufficient size to benefit from the type of planning outlined in this article. The article is aimed at investors with portfolios in the £50,000 to £250,000 range, and for such investors more advanced tax planning, such as the use of trusts, is probably not a realistic option.

Avoiding CGT altogether

The easiest way to avoid CGT is to build up a portfolio by using stocks and shares ISAs because chargeable gains will be tax free. However, such a strategy will be constrained by the annual investment limit (currently £15,240), and it is not possible to transfer existing shareholdings into an ISA because subscriptions must normally be in the form of cash.

If a share portfolio is retained until death, then the shares will be completely exempt from CGT - and therefore there is no need for any CGT planning. However, people may have to sell shares later in life to top up their pension and investment income, whilst many other investors prefer to actively trade shares rather than just retaining the same portfolio. Such an approach must also be balanced against the possible inheritance tax implications. Although retaining a share portfolio until death will avoid CGT, this may not be beneficial where the value of the portfolio is high in relation to the amount of chargeable gains. For example, a person has a share portfolio valued at £200,000 with potential chargeable gains of £50,000. Retaining the portfolio until death will result in a maximum CGT saving of £14,000 (£50,000 at 28%), but the inheritance tax cost could be £80,000 (£200,000 at 40%).

It is also possible to avoid CGT by becoming non-UK resident, although it is necessary to be non-resident for a period of more than five years. Obviously, such tax planning is not appropriate for people with the modest share portfolios being discussed here, but if someone is already planning to retire overseas it would make sense to delay disposals until after they have left the UK – assuming of course that the gains will not be taxed in the new country of residence.

Deferring gains

The only relief which is likely to be available is reinvestment relief as a result of investing in shares that qualify for the enterprise investment scheme. Such an investment is probably too risky for our investor, but it might be appropriate where an investor is investing in their own company (for reinvestment relief, it does not matter if the investor is connected with the company). It is not particularly difficult for a company to become an enterprise investment scheme company (simply complete form EIS1), with the main limitation being that certain types of trade are excluded.

The investment must be made within a period starting one year before and ending three years after the date of the disposal. It is only necessary to reinvest the amount of chargeable gains in order to obtain full deferral, and there is no upper limit to the amount of gains that can be deferred. Gains are only deferred until the enterprise investment scheme shares are disposed of, but if the shares are held until death the deferred gains will then be exempt.

There is also the option of investing up to £100,000 per year in shares that qualify for the seed enterprise investment scheme, although no reliefs are available for someone investing in their own company. An investment provides 50% exemption for reinvested gains plus income tax relief at the rate of 50%. The total potential tax relief of 64% (50% + (half of the higher CGT rate of 28%) might therefore make such an investment attractive despite the risk of investing in very small companies – and there is further relief should the shares become worthless.

Basic tax planning

When it comes to basic CGT planning, there are three main things to consider.

Firstly, maximise the benefit of the annual exempt amount – currently £11,100. This can be achieved by making sufficient disposals each tax year so that chargeable gains are at least £11,100.

Secondly, where CGT will be payable, then (all other things being equal) delay a disposal until the start of the following tax year because the due date will then be one year later. For example, for a disposal made on 4 April 2016, the due date will be 31 January 2017, but it is 31 January 2018 for a disposal made on 6 April 2016.

Finally, minimise the rate of CGT by making disposals during a tax year when an investor has some of his or her basic rate tax band available. Chargeable gains are taxed at the lower rate of 18% when they fall within the basic rate tax band (currently £31,785) and at the higher rate of 28% when they exceed this threshold. There are several relevant points here:

  • Where an investor’s taxable income is consistently below £31,785, then disposals could be spread over several years so that CGT is at the 18% rate rather than 28%. This strategy also fits in with utilising the annual exempt amount.
  • The basic rate band is extended if a person makes personal pension contributions. Therefore, matching disposals and pension contributions to the same tax year could reduce the rate of CGT payable.
  • Some investors may have fluctuating taxable income. This could be because a self-employed person makes a loss, or because an employee is posted overseas for a year (with their earnings being outside the UK tax net). In such a year, all or most of a person’s basic rate tax band might be available, so it will be a good time to make disposals. Directors of owner-managed companies who withdraw profits mainly by way of dividends could forego dividends for one year to achieve the same result.
  • Similarly, a self-employed person could aim to make disposals in the same year in which they incur expenditure qualifying for the 100% annual investment allowance – thus reducing their taxable profits.

For example, over the next 12 months an investor wishes to make disposals of shares which will result in chargeable gains totally £60,000. The investor’s annual taxable income is £17,500. If the disposals are made entirely in the current tax year, then the CGT liability will be:

CGT  14,285 (31,785 – 17,500) at 18% 2,571
34,615 (48,900 – 14,285) at 28% 9,692

Spreading the disposals over this and the next tax year, will reduce the total CGT to £7,726 (based on 2015-16 tax rates), and also delay the payment of some of the liability by one year.

Married couples and civil partners

For married couples and civil partners, the basic tax planning outlined above can be extended further. Prior to their disposal, shareholdings could be transferred to a spouse or civil partner if that person has some of their annual exempt amount or basic rate tax band available. Alternatively, shareholdings could simply be held in joint names.

If one spouse (or civil partner) is a higher rate taxpayer and the other has little or no income, the potential CGT saving each tax year is £6,286 ((£11,100 at 28%) + (£31,785 at 10% (28% - 18%))).

Bed and breakfasting

Bed and breakfasting is when shares are sold (bedded) at the close of business one day and then bought back (breakfasted) at the opening of business the following day. This practice means that a chargeable gain can be realised to make use of the annual exempt amount, or a capital loss can be established. Although traditional bed and breakfasting is prevented by matching disposals with shares purchased within the following 30 days, there are still ways in which a similar outcome can be achieved:

  • Shares can be sold and bought with the two transactions at least 30 days apart - the investor will therefore be exposed to real price movements.
  • By making use of an ISA – shares are sold as normal, but the matching acquisition is then made within an ISA. The ISA investment limit of course somewhat limits the scope of this method.
  • The matching rules only apply when the same class of share in the same company is being sold and then reacquired. An investor is therefore quite free to sell shares in one company and then to immediately acquire shares in another, similar, company. For example, if a shareholding in Lloyds Bank was sold, then it could be replaced by a similar value holding in Barclays Bank, thus maintaining a broadly similar portfolio. If desired, the position could be reversed after 30 days so that the investor again holds shares in the original company.
  • Spouses or civil partners can jointly undertake a bed and breakfasting arrangement. For example, a wife could sell shares with the husband acquiring an equal number of shares in the same company. Overall the couple have maintained exactly the same share portfolio. Of course the shares must actually be sold and acquired – it is not sufficient to simply make a transfer between spouses as this would be ineffective for CGT purposes (being at no gain, no loss). If desired, the position could be reversed after 30 days by making a transfer of the shares back to the spouse or civil partner who originally held them. A similar strategy could be followed by an unmarried couple. Care must be taken to ensure that a bed and breakfasting arrangement of this nature is not invalidated by the capital loss targeted anti-avoidance rule.

The transaction costs of undertaking a bed and breakfasting arrangement should not be overlooked, with charges likely to be higher than was previously the case with traditional bed and breakfasting.

Capital losses

Capital losses can only be set off against chargeable gains made in the same tax year or carried forward against future gains. Careful planning is therefore necessary in order to make the best use of capital losses. The main problem is that capital losses of the same year have to be fully set off against gains, which means that the annual exempt amount may be wasted. In contrast, where capital losses are brought forward it is only necessary to offset sufficient losses to bring gains down to the level of the annual exempt amount.

For example, for 2015-16, an investor has chargeable gains of £10,000 and capital losses of £12,000. Although the gains are covered by the annual exempt amount, it is still necessary to offset £10,000 of the capital losses, leaving just £2,000 of losses to carry forward to 2016-17. The investor could have taken any of the following approaches to avoid this problem:

  • Making further disposals during 2015-16 so that chargeable gains totalled at least £23,100. This would leave gains of £11,100 after offsetting the capital losses.
  • Postponing the disposals that resulted in the chargeable gains until 2016-17. The losses would then be fully carried forward to future tax years (unless of course further gains are made in 2016-17). Alternatively, the investor could have arranged for the gains to have been incurred by a spouse or civil partner.
  • Postponing the disposals that resulted in the capital losses until 2016-17. The losses would then be fully carried forward. Alternatively, the investor could have arranged for the capital losses to have been incurred by a spouse or civil partner.


Tax planning with quoted shares generally means incurring immediate transaction costs in order to save future CGT. Brokerage fees will typically start at around £10 per transaction, and there will also be stamp duty at the rate of 0.5% on the cost of shares purchased. These costs can easily mount up if dealing with a number of small shareholdings.
