The Octopus AIM Inheritance Tax Service has been managed by the Octopus UK Smaller Companies investment team since 2005. The team manages £2.7 billion in UK quoted companies and is also responsible for the Octopus AIM VCTs, the Octopus UK Micro Cap Growth fund and the Multi-Cap Income fund. The team has built a strong performance track record and a large following of investors: note past performance is not a guide to the future. 

The AIM IHT service has a growth-oriented investment approach. It seeks to invest in companies with dominant market positions in growth markets, often much larger companies than one might expect when considering an AIM investment. The average market cap of an investee company in the service is over £913 million, and 31% of the buy-list portfolio is valued at more than £1 billion. 

We believe this is an attractive offer for wealthy or sophisticated investors considering an AIM IHT portfolio. The service is available both in and outside an ISA.

Important: The information on this website is for experienced investors. It is not advice nor a research or personal recommendation to invest. If you’re unsure, please seek advice. Investments are for the long term. They are high risk and illiquid and can fall as well as rise in value, so you could get back less than you invest.

An AIM ISA lets you hang on to the ISA perks of tax-free growth and income yet also potentially pass on your ISA IHT free. This is thanks to Business Property Relief (BPR) which is available for certain AIM shares. If you hold the shares for at least two years and on death, under current rules they should be free of IHT. Tax rules can change and benefits depend on circumstances.

The manager

The AIM IHT Service is managed by the Octopus Quoted Smaller Companies investment team, which manages £2.7 billion in quoted investments across all Octopus products (June 2021). As the name suggests, smaller company investing takes up 100% of the team’s time.

Headed up by Richard Power and Kate Tidbury, the team of nine has more than 100 years of industry experience. Together they conduct more than 650 company meetings per year to help identify what they believe are the best investment opportunities. This level of activity is likely to be hard to replicate by competitor AIM IHT providers. The dedicated investment resource is a key differentiator for the Octopus AIM IHT service, in our view. 

Overall, the wider Octopus Group manages £10.1 billion (March 2021) on behalf of over 63,000 clients. 

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

Investment strategy

There are over 800 companies on AIM – but only 20-30 make it into the service. 

The companies held are not fledgling businesses. Octopus looks for established firms with growth potential, with 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
  • Ability to pay dividends 

Current portfolio overview

One of the key tenets of the investment strategy is to back businesses with strong market positions. Therefore, companies in the portfolio tend to be larger than one might expect. In fact, the average market value of the portfolio companies is £913 million (June 2021). 31% of the buy-list has a market cap greater than £1 billion. Just 6.9% of the portfolio is valued at less than £250 million.

There are currently 29 companies on the Octopus investment team’s “buy list”. The buy list contains stocks 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 has a bias towards software and computer services businesses across diverse sectors. 

The chart below shows the portfolio sector breakdown for the top 10 sectors, which together account for c.79% of the portfolio.

Examples of portfolio companies

RWS Holdings – Octopus AIM IHTRWS Holdings Plc

RWS Holdings is a leading provider of intellectual property support services and high-level technical translation services. The group translates over 50,000 patents a year for clients in the legal, financial, medical, pharmaceutical, chemical, engineering and telecom sectors. 

Octopus Investments has been a patient long-term shareholder having first invested in the business in 2005 when RWS had a market cap of less than £110 million. Currently, RWS is one of the 10 largest companies on AIM, with a market cap of £2.7 billion. Since flotation in November 2003, the company has had 17 consecutive years of growth in revenues, profits and dividends (to September 2020). The company has grown both organically and through acquisitions. In November 2020, RWS completed the acquisition of translation software company SDL, to create the world’s largest language services company. As a result, the combined group reported revenues of £326.4 million for the six months to 31 March 2021, up from £169.7 million the previous year. Past performance is not a guide to the future. 

Renew Holdings – Octopus AIM IHTRenew Holdings Plc

Renew Holdings plc provides specialist engineering services to maintain and develop energy, environmental and infrastructure assets. The holding company operates a number of subsidiary businesses that provide engineering services to the UK infrastructure market. Key sectors include highways, rail, nuclear, water, and telecoms.

In 2020, the business generated £620.4 million in revenue and £32.9 million in profit (as at 8 December 2020). Past performance is not a guide to the future. Octopus has been an investor in the business since 2007 and is currently its largest shareholder.

Staffline Group Plc

As is to be expected, not all investments work out. A recent example is Staffline Group plc. 

Outsourcing specialist Staffline Group plc saw its shares suspended 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, however, it has recently announced a pre-tax loss for the first half of 2019 and has suspended dividend payments until at least 2021. 


Octopus has a solid long-term track record. Since launching the service, from June 2005 to June 2021 the service has delivered returns of 320.59%, equivalent to a return of 9.39% per annum: past performance is not a guide to the future. 

The chart below shows performance over five years compared with other AIM IHT portfolios available through Wealth Club. Like other IHT portfolios, this is a discretionary managed service so each portfolio is likely to be different.

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 of course no longer be IHT free and will lose its ISA tax benefits.

Risks – important

This, like all investments available through Wealth Club, is only for experienced investors happy to make their own investment decisions without advice.

AIM IHT portfolios are high-risk so should only form part of a balanced portfolio and you should not invest money you cannot afford to lose. Before you invest, please carefully read the Risks and Commitments and the offer documents to ensure you fully understand the risks. 

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 of AIM-listed shares is often wider than the spread for shares listed on the main market.

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.

Tax rules can change and benefits depend on circumstances. Eligibility for BPR 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.

Treasury review

A previous Chancellor requested a review of IHT to simplify the tax system. A report was published in July 2019, but this has not yet led to any rule changes. Please remember, tax rules can and do change and benefits depend on circumstances.

Our view

This is a longstanding Inheritance Tax service with a strong performance track record, though there is no guarantee of future performance. The service is well resourced. You’re investing in the largest AIM IHT offering by some distance. In our view, the team’s size and level of funds under management could provide excellent access to underlying companies and allows the team to produce the breadth of high-quality research needed to build an AIM portfolio. However, it may also mean the portfolio is less nimble than its peers. 

If you’re an experienced investor looking for an AIM ISA, we believe the Octopus AIM service is worthy of consideration. It also has a minimum of £20,000 which could make it a contender for this year’s ISA subscription.
