Investment Tax Reliefs: Are You Claiming What You’re Entitled To?

Many UK investors unintentionally miss out on legitimate investment tax reliefs simply because the rules are complex and change year to year. Whether you invest personally, through a company, or as a high-earning individual managing significant gains, the UK tax system includes several reliefs designed to reduce the tax you pay on investment profits.

This article outlines the major investment tax reliefs that are available today, how they broadly work, and what they mean from a tax-planning perspective. For tailored guidance on your circumstances, our tax compliance and planning services can help you navigate these options.

Capital Gains Tax Reliefs: The Foundation of Investment Tax Planning

Capital Gains Tax (CGT) applies when you sell investments, property that isn’t your main residence, or other chargeable assets. Understanding the allowances and reliefs can prevent unnecessary tax.

Most investors benefit from:

Annual exemption: £3,000 for 2025/26
Rates: 10% or 20% depending on income (with different rates for residential property)

Gains can also be reduced through:

1. Using your annual exemption each year: Because the exemption is “use it or lose it,” investors often realise gains gradually across multiple tax years. Our article on chargeable gains in 2025 explains how timing decisions can reduce overall tax.

2. Offsetting losses: Unused capital losses can be carried forward indefinitely, provided they were reported to HMRC within the required timeframe.

3. Spouse or civil partner transfers: Assets can be transferred between spouses without triggering CGT, allowing two annual exemptions and potentially lower tax bands to be used.

These rules form the base layer of any investment tax strategy, regardless of whether you invest in shares, property, or more specialist schemes.

Venture Capital Trusts (VCTs): Income Tax Relief for Established Investors

Venture Capital Trusts are HMRC-recognised vehicles that invest in early-stage companies. From a tax perspective—not from an investment recommendation—they offer several reliefs under the government’s venture capital schemes.

Current rules available on the GOV.UK guidance on venture capital schemes tax relief for investors include:

• Up to 30% income tax relief on new VCT subscriptions (subject to limits)
• Tax-free dividends from the VCT
• Tax-free growth on disposal of VCT shares (if conditions are met)

These reliefs exist to encourage investment into smaller UK businesses but should always be understood carefully due to the underlying investment risk. From a tax viewpoint, they can complement pension planning for high earners who already use their annual allowance.

Enterprise Investment Scheme (EIS): Reliefs When Investing in Higher-Risk Companies

The Enterprise Investment Scheme provides generous tax reliefs to investors who support early-stage businesses. The government outlines the rules in its guidance on venture capital schemes.

Key reliefs include:

• Up to 30% income tax relief
• Capital Gains Tax deferral relief
• No CGT on disposal if conditions are met
• Potential loss relief on qualifying investments

From a tax-planning perspective, EIS can help:

• Reduce current-year income tax
• Defer CGT from the sale of other investments
• Mitigate risk through available loss relief

EIS is a common route for investors who have already maximised pension contributions and ISA allowances.

Seed Enterprise Investment Scheme (SEIS): Higher Reliefs for Early-Stage Startups

SEIS sits alongside EIS, but applies to much smaller, earlier-stage companies. It offers enhanced reliefs, set out in the British Business Bank summary on the Seed Enterprise Investment Scheme.

Reliefs include:

• 50% income tax relief on qualifying investments
• Reduced CGT on reinvested gains
• No CGT on disposal of qualifying SEIS shares after the holding period
• Loss relief where investments fall in value

These enhanced reliefs reflect the higher risk profile. From a tax viewpoint, SEIS is most often used strategically alongside wider investment and CGT planning.

Bringing It All Together: Tax Planning, Structure and Timing

Investment tax reliefs work best when coordinated with your broader financial position. Key factors include:

1. Your income level: This determines tax bands, dividend rates, and the value of income tax relief.

2. The timing of gains: Transactions straddling tax years can significantly change the final tax position.

3. Your company structure: Directors taking income via dividends or salary—including those using alphabet shares—may benefit from aligning investment decisions with remuneration planning.

4. Your wider portfolio: Chargeable gains, allowances, spouse exemptions, and pension contributions all interact with investment reliefs.
