The Service 

Puma AIM offers a discretionary portfolio service that seeks to deliver long term growth whilst mitigating Inheritance Tax. It aims to mitigate Inheritance Tax by the use of Business Relief (BR), which takes effect after just two years from the acquisition of qualifying AIM stocks. The minimum subscription to the service is £20,000, with no maximum. One key benefit is that investors retain control over their assets, thus avoiding the need to gift their assets or place them in trust in order to mitigate Inheritance Tax.


Puma Investments is an award winning investment manager, having won 'Best AIM Investment Manager' for a second year in a row at the Growth Investor Awards 2017.

Development of the AIM market

In 1995, the London Stock Exchange launched a junior stock market for small growing companies - the Alternative Investment Market (AIM). AIM allows investors access to growth companies, as well as giving these companies access to investor capital with fewer limitations and costs that come with a full Stock Exchange listing. 

Development of AIM

AIM is now home to just under 1,000 companies, joining either through Initial Public Offerings or by moving from the main market. The total market value of AIM (as at 30 April 2019) is £104bn.

While AIM is traditionally associated with smaller companies, the composition of the market has developed; (as at 30 April 2019) 347 AIM-listed companies with a market value of at least £50m, and 16 companies with a value greater than £1bn. AIM’s largest company has a market capitalisation of £3.6bn.

How the Service Works

The Puma AIM Inheritance Tax Service targets investments in companies listed on AIM that benefit from BR. To qualify for BR you (the investor) must retain beneficial ownership of the underlying shares. 

This is achieved via a discretionary portfolio management service. The investor can access this through either a new or existing ISA account, an investment account outside your ISA or a combination of the two. You can even transfer from your investment account to your ISA as your ISA allowance becomes available (please note this will incur dealing fees). 

Investment Strategy

We focus on investing in quality companies with strong margins, good returns and a track record of cash generation. We select companies on strict valuation criteria with a focus on capital preservation. We seek to invest in companies which can deliver solid long term growth. Our approach is research driven and we only select investments after intensive financial and business analysis.

Portfolio Construction

  • All investors are broadly aligned to the Puma AIM Inheritance Tax model portfolio
  • Fully invested in AIM shares, with only a small cash position (approximately 2-5%)
  • Target approximately 20 to 25 holdings
  • Average position size is 2%-6%, with generally no position greater than 10% of the portfolio
  • Target hold for investments of three to five years
  • Longer-held positions are considered if fundamentals improve and valuations remain sensible
  • Low portfolio turnover


Inheritance Tax Benefits

Under current UK legislation, an individual’s estate worth more than £325,000 (the nil rate band) is subject to 40% Inheritance Tax, payable after death. For married couples, no tax is charged on the first death if the entire estate is left to the spouse. On the second death, the two nil rate bands are available (£650,000). The value of an estate (minus any outstanding allowable debts) includes not only the assets (such as properties and investments) but also any gifts made in the seven years prior to death, as well as life assurance policies or pension plans not held in trust.

How Investing in AIM Mitigates Inheritance Tax
The Service seeks to invest in companies that benefit from Business Relief (BR). BR is a relief by which investment in certain types of businesses and business assets can receive 100% relief from Inheritance Tax after just two years. This includes many (but not all) of the companies listed on AIM. The purpose of this relief is to encourage the support of small and medium size trading businesses. These businesses are often family owned and controlled and would be significantly impacted should their owners be subject to Inheritance Tax on their transfer between generations. In addition, as of April 2015, no stamp duty is charged on purchases of AIM Shares.

Investing in AIM stocks can significantly reduce your IHT liability. 

Tax reliefs depend on individual circumstances, minimum holing periods and may be subject to change.

Available in ISAs

The Puma AIM Inheritance Tax Service is also available in ISAs. This allows you to add Inheritance Tax relief to the Income Tax and Capital Gains Tax relief that an ISA already gives you. 

Whilst ISAs are extremely tax efficient during the holder’s lifetime, upon death ISA balances may be subject to a 40% IHT liability. Investing in a BR-qualifying portfolio of AIM stocks allows you to mitigate Inheritance Tax while still retaining the benefits of an ISA.

It is easy to start a new ISA as the minimum subscription for the Puma AIM Service of £20,000, the current annual ISA allowance. Of course, you can transfer in all or part of an existing ISA to enable you to benefit from the Puma AIM Service. An investment in BR qualifying AIM stocks allows you to mitigate Inheritance Tax while retaining the tax benefits of an ISA.


The Puma AIM Inheritance Tax Service is managed by Puma Investments. Puma Investments is a trading name of Puma Investment Management Limited which is authorised and regulated by the FCA. The management team at Puma Investments have an 21 year track record of investing in small and medium sized enterprises.

Risk Factors

An investment in the Puma AIM Inheritance Tax Service may not be suitable for all investors.

Investors can only invest in the Service through a Financial Adviser who has assessed that an investment in the Service is suitable for the investor.

Tax reliefs are not guaranteed
Tax rules may change, which could affect the reliefs available for IHT purposes. Tax reliefs are subject to an individual’s personal circumstances and independent tax advice should be taken. While the Tax Adviser will also carry out an annual review of the portfolio, we can’t guarantee that all portfolio investments will qualify for BR. If a company should be non-qualifying at the time of being selected for the portfolio or become non-qualifying thereafter, then any applicable BR could be reduced accordingly.

Long-term investment
An investment in the Puma AIM Inheritance Tax Service should be considered a long-term investment.


Capital at risk
The value of investments can go down as well as up, so investors may not receive their full amount invested. An investment in smaller companies is likely to be higher risk than many other investments. Companies quoted on AIM are likely to be more risky and have less rigorous listing requirements than companies quoted on the main list of the London Stock Exchange.

Dealing costs may be significant, particularly in respect of a relatively small investment in the Service.

Past performance
The past performance of the Puma AIM Inheritance Tax Service, Puma Investments, the funds Puma Investments manages or the companies it advises, is not a reliable indicator of future performance. Future performance may be materially different from past results. There is no guarantee that can be given as to the overall performance or level of return that can be achieved from investments made, or that the objectives of the Service will be achieved.

Potentially illiquid investment
AIM stocks are largely small and illiquid. They are characterised by significant spreads and low trading volumes. A sale of such shares may be difficult, slow and only achievable at lower than indicated market price.
