EIS and SEIS Tax Relief for UK Investors Who Back British Startups
Investing in qualifying startups through EIS or SEIS can deliver significant income tax relief, CGT exemptions, and loss protection. ABM Chartered Accountants makes sure your claims are submitted correctly, your carry-back elections are timed properly, and every available relief is secured.
Venture Capital Tax Reliefs Claimed With Precision
The Enterprise Investment Scheme and Seed Enterprise Investment Scheme offer some of the most generous tax reliefs in the UK. EIS provides 30 percent income tax relief on up to one million pounds invested per year, while SEIS provides 50 percent relief on up to 200,000 pounds. ABM Chartered Accountants claims these reliefs accurately on your return.
Our ICAEW and ACCA qualified accountants handle income tax relief claims, CGT deferral for EIS and reinvestment relief for SEIS, loss relief when investments fail, carry-back elections to the previous tax year, and compliance certificate submissions for companies issuing qualifying shares to investors.
What Our EIS and SEIS Service Covers
From claiming your income tax relief to supporting advance assurance applications, here is how ABM Chartered Accountants helps you get the most from venture capital reliefs.

Advance Assurance Support
Helping companies apply to HMRC for advance assurance that a share issue will qualify for relief.

Reduce Your Tax Bill While Backing Innovation
EIS and SEIS were designed to reward investors who take the risk of funding early-stage businesses. The tax reliefs are generous but the rules are strict. A missed deadline, an incorrect claim, or a failure to meet the three-year holding period can result in clawback. ABM Chartered Accountants ensures every claim is made correctly and protected.
From April 2026, EIS qualifying limits increase, with company gross asset thresholds rising to 30 million pounds and annual fundraising limits doubling to 10 million pounds. These changes mean more companies will qualify, creating more investment opportunities. We keep you informed of every rule change that affects your reliefs.

Frequently Asked Questions
Here are answers to the EIS and SEIS questions we hear most often. Contact our team for guidance.
What is the difference between EIS and SEIS?
SEIS targets very early-stage companies with income tax relief of 50 percent on up to 200,000 pounds per year. EIS targets slightly later-stage companies with 30 percent relief on up to one million pounds. Both offer CGT benefits and loss relief, but the qualifying conditions differ.
How do I claim EIS or SEIS income tax relief?
You claim relief on your self assessment return using the EIS3 or SEIS3 compliance certificate issued by the company. You can also request an in-year adjustment to your PAYE tax code. ABM Chartered Accountants handles the claim and ensures the correct amount is included.
Can I defer capital gains through EIS?
Yes. If you reinvest a capital gain into qualifying EIS shares within one year after or three years before the gain arose, the gain is deferred until the EIS shares are disposed of. There is no limit on the amount of gain that can be deferred.
What happens if my investment fails?
If your EIS or SEIS investment becomes worthless, you can claim loss relief. The loss is the original investment minus any income tax relief already received. You can offset this loss against your income tax or your capital gains in the year of disposal.
What changed for EIS from April 2026?
From April 2026, the company gross asset limit for EIS rises from 15 million to 30 million pounds. The annual fundraising limit doubles from 5 million to 10 million pounds, and the lifetime limit rises from 12 million to 24 million pounds. SEIS limits remain unchanged.
How much does EIS and SEIS advice cost?
Fees depend on whether you are an investor claiming reliefs or a company seeking advance assurance and compliance certificates. We offer fixed-fee pricing for both. Contact ABM Chartered Accountants for a quote based on your specific requirements.
