Octopus AIM IHT ISA

Launched in 2005, the Octopus AIM Inheritance Tax Service is the largest AIM IHT offering, with £1.2 billion in assets under management (June 2025).

The service is managed by a well-resourced and experienced team of 13, which oversees £1.7 billion of quoted investments across all the Octopus products, including the AIM IHT Service (June 2025).

Overall, the Octopus Investments group manages £9.9 billion on behalf of its clients (June 2025).

The team targets more established AIM-quoted companies with strong market positions and growth potential.

• Portfolio of 20-30 stocks
• Bias towards large and well-established growth focussed companies
• Minimum investment £20,000 (£25,000 outside an ISA) – you can apply online (ISA only)

The AIM IHT Service is managed by the 13-strong Quoted Companies team, which has more than 100 years of industry experience and oversees £1.7 billion in quoted investments across all Octopus products (June 2025). 

The team is headed up by Richard Power and Kate Tidbury. Kate first joined Octopus as a fund manager of smaller companies in 2008, while Richard joined Octopus in 2004 and has worked in smaller company investing for over 25 years. 

The team conducts more than 850 meetings a year to help identify what they believe are the best investment opportunities. This level of activity may be hard to replicate by smaller AIM IHT providers. The dedicated investment resource is a key differentiator for the Octopus AIM IHT service, in our view. 

Overall, Octopus Group manages £9.9 billion on behalf of over 70,000 clients (June 2025). 

Octopus will hold your shares on your behalf using its own nominee company.

The Service's buy list typically includes 20-30 stocks at any one time.

Octopus looks for established firms with growth potential and one or more of the following characteristics:

• Strong market position or global leader in its field 
• Scalable growth-focused business model 
• Proven management team with a successful track record 
• Strong balance sheet, preferably showing profitability 
• High level of recurring revenues and earnings visibility 

New investors will receive shares in the companies on Octopus’ buy list at the time of their investment.

Companies are sometimes moved from the buy to the hold list for a variety of reasons. This means they will not be included in newer portfolios but will be retained in existing portfolios. Companies will only be removed from investors’ portfolios if the managers feel the outlook for the company has significantly deteriorated.

One of the key tenets of the Octopus AIM IHT Service’s investment strategy is to back businesses with strong market positions. Therefore, companies in the portfolio tend to be larger than one might expect, with average market value of £406.2 million (June 2025).

Currently, the buy list comprises of 32 companies the team deems suitable for investment. Whether these stocks are included within a specific client’s portfolio – and in what size – will be determined at the discretion of the investment team based on liquidity and market conditions. As this is a discretionary service, each client portfolio is slightly different. 

The buy list currently has a bias towards industrial and technology businesses.

Currently, around 35% of the buy list has a market cap valued at less than £250 million.

The charts below show the sector and market capitalisation breakdown for the current buy list.

As is to be expected, not all investments work out. One example is Staffline Group. 

Outsourcing specialist Staffline Group saw its shares suspended in 2019 following a 46.0% decline in its share price. This was due to a delay in releasing its full-year results following allegations of improper invoicing and payroll practices. Trading resumed in March 2019 following the company's refinancing but continue to trade at a fraction of what they were worth prior to the episode. 

Access to your investment

Investments in this portfolio are for the long term. However, if your circumstances change, you can sell some or all of your shares, although sometimes this can take a while depending on market conditions and liquidity. You can arrange to take regular withdrawals from the account, which you can change or stop at any time. Any amount you withdraw will no longer benefit from IHT relief. Withdrawals may result in a Capital Gains Tax liability unless held in an ISA.

This, like all investments available through Wealth Club, is only for experienced investors happy to make their own investment decisions without advice. Those considering AIM Inheritance Tax Portfolios should be comfortable with the significant risks of investing on AIM.

AIM IHT portfolios should only form part of a balanced portfolio. Your capital is at risk and you should not invest money you cannot afford to lose. If a service is managed by a small investment team, it could create key person risk. The fewer the companies included in the portfolio, the higher the risk of loss if things don’t go to plan. 

AIM stocks can be hard to sell, particularly at the smaller end of the market, and can be illiquid. AIM shares can be very volatile especially if the market falls sharply. The difference between the buying and selling price (spread) of AIM shares is often wider than the spread for shares listed on the main market. 

Eligibility for BPR, based on current rules, is assessed at the date of death and will depend on the companies in the portfolio remaining qualifying. Broadly speaking, you will need to have held a BPR qualifying stock for at least two years and still hold it on death to qualify. Tax rules can change and benefits depend on circumstances.

Before you invest, please carefully read the Risks and Commitments and the offer documents to ensure you fully understand the risks. 

This is the largest AIM IHT portfolio. The manager may find itself less able to act as quickly as smaller AIM ISA providers, which could impact the fund if market sentiment changes or if AIM rules change. 

In the Budget 2024, it was announced that from 6 April 2026 AIM shares will be eligible for 50% IHT relief (currently 100%).

This is a longstanding portfolio managed by a large, well resourced and experienced team. At £1.2 billion assets under management, it is the largest AIM IHT offering by some distance.

In our view, this scale has several advantages. Firstly, the level of funds under management should ensure the team has excellent access to AIM company management teams. Secondly, it should support a well resourced investment team capable of producing the breadth of high-quality research needed to build an AIM portfolio. However, scale also has disadvantages: the portfolio may be less nimble than its smaller peers, and some smaller company opportunities may be out of reach of the service.

The portfolio’s fees are higher than some of its peers. The minimum of £20,000 could make it a contender for this year’s ISA subscription.
