Benefits of an AIM Inheritance Tax Portfolio

After two years, AIM shares should qualify for 50% business relief (from April 2026), helping to reduce your client’s IHT liability. There is no upper limit, as business relief can apply to an unlimited investment value in alternative investment market (AIM) shares.

Dedicated team

Your client's investments will be looked after by a dedicated team with specialist expertise in financial portfolio management and inheritance tax mitigation strategies.

Diversified investments

Your client’s AIM portfolio will be constructed with between 25 and 30 AIM shares, diversified across a range of industry sectors to spread risk.

Tailored to your client’s needs

Although our AIM IHT portfolios are managed in line with our house model, each client's portfolio is bespoke, so we can help manage their capital gains tax liabilities and make annual ISA subscriptions.

Tax efficient

Use your client's ISA allowance to benefit from tax-free growth and income. And if the shares have been held for at least two years (and at the time of death) they should qualify for 50% business relief on AIM shares. This will reduce your client’s IHT liability, whilst ensuring they retain full access to their funds.

Expert guidance

The team has been managing AIM portfolios since 2004 and we use a specialist firm to independently review the qualifying status for business relief on all investments.

      Frequently asked questions

      AIM was established in 1995 and is the London Stock Exchange’s market for smaller, growing companies. With a unique regulatory structure, it’s an attractive market for a wide range of companies at different stages of development. Charles Stanley IHT portfolios have consistently performed better than the AIM market average since inception in 2012.

      AIM shares are publicly-listed, smaller UK companies which you can buy and sell on the London Stock Exchange’s junior market – the Alternative Investment Market.

      If held for more than two years, qualifying AIM shares aren’t subject to inheritance tax (IHT). However, from April 2026, the rules are changing so IHT relief will be reduced to 50%.

      Qualifying AIM shares that are held for a minimum of two years (and held at the time of death) will qualify for 50% business relief (from April 2026) – which is effectively a reduced rate of 20% IHT. If the two-year holding period is not met, the surviving spouse can inherit the portfolio without restarting the required holding period.

      Your client can also hold AIM shares in their ISA, which will be free from capital gains tax, income tax and have the potential to reduce IHT liability (if held for at least two years). This makes an AIM ISA one of the most tax-advantageous portfolios a client can hold.

      ISAs fall within the value of the estate for inheritance tax purposes. However, if the deceased is married or in a civil partnership, the survivor will benefit from additional permitted subscription (APS). This additional allowance is on top of their annual allowance (currently £20,000) and the APS is based on the value of the deceased’s ISA at time of death.

      Business Relief (formerly known as Business Property Relief) is a statutory tax relief introduced by the UK Government in 1976. It is an incentive for investing in specific types of trading companies including companies quoted on the Alternative Investment Market (AIM).

      The requisite two-year holding period starts from the date each underlying investment is made and unless instructed otherwise we typically seek to invest the proceeds over two or three months to reduce market volatility.
