In the UK, the Seed Enterprise Investment Scheme (SEIS) and the Enterprise Investment Scheme (EIS) offer incredible incentives for investors to back early-stage businesses. However, the process of applying for SEIS/EIS can feel daunting. This guide breaks down the application process so your business can confidently attract investors.
What Is SEIS and EIS?
SEIS: Designed for early-stage businesses, SEIS offers investors tax reliefs of up to 50% on investments of up to £250,000.
EIS: Suitable for slightly more mature businesses, EIS allows investments up to £10 million annually and up to £24 million in total, with tax reliefs of 30% on investments of up to £1 million per tax year.
Both government-backed schemes aim to encourage private investment in high-risk, high-potential startups. The tax incentives can be a game-changer in attracting funding, but the key lies in presenting a solid application. Here’s a step-by-step breakdown to streamline your application process.
Step-by-Step Guide: How to apply for SEIS/EIS
Step 1: Confirm Your Business Eligibility
The first step is confirming your SEIS eligibility or EIS eligibility. These schemes have strict requirements, so verifying them early is crucial.
- Business Age: SEIS applies to companies less than 3 years from their first commercial sale, while EIS extends to companies up to 7 years old (or 10 years for knowledge-intensive companies).
- Gross Assets: Your company’s gross assets must not exceed £350,000 for SEIS or £30 million (before investment) for EIS.
- Employee Count: SEIS limits your full-time employee count to fewer than 25, while EIS caps it at 250 (or 500 for knowledge-intensive companies).
- Qualifying Trades: Certain industries, such as financial services and property development, are excluded.
Tip: Use HMRC’s guidance to double-check your trade and financial structure against the scheme’s requirements.
Step 2: Prepare Your Business Plan and Financials
A strong SEIS/EIS application requires more than ticking eligibility boxes. You need a compelling business plan and robust financials that showcase your growth potential.
- Business Plan: Highlight your unique value proposition, market opportunity, and scalability. Investors need to see the growth potential.
- Financial Projections: Include detailed forecasts demonstrating how the funding will be used and the expected returns.
- Pitch Deck: A concise and visually appealing pitch deck can complement your application.
Step 3: Apply for Advance Assurance
If you’re a startup aiming to attract early-stage investors through the Seed Enterprise Investment Scheme (SEIS) or the Enterprise Investment Scheme (EIS), securing Advance Assurance from HMRC can give you a competitive edge. While it’s not compulsory, it’s highly recommended and often expected by investors.
What is Advance Assurance?
Advance Assurance is confirmation from HMRC that your business is likely to qualify for SEIS or EIS once you’ve raised investment. It reassures investors that they can claim tax relief when they back your business.
Are You Eligible?
Before applying, ensure your business meets HMRC’s eligibility criteria, including:
- Trading start date: This determines your scheme eligibility.
- Previous investments: Check any funding received under SEIS, EIS, or similar schemes.
- Risk to capital condition: Your business must show growth potential and involve genuine risk for investors.
- Fundraising proposal: Outline how you’ll use the investment.
Advance Assurance Process
1. Check your eligibility
Review HMRC’s SEIS or EIS requirements to confirm your business qualifies.
2. Prepare key documents
Gather the following essentials:
- A three-year business plan or pitch deck
- Financial forecasts
- Your Unique Taxpayer Reference (UTR)
- Evidence of prior funding (if applicable)
- A register of members and company details
- Show Investor Interest
HMRC requires proof of interest from at least one investor. This could be a letter of engagement from an individual, a VC firm, or a crowdfunding platform.
3. Address the “Risk to Capital” condition
Unlike when pitching to an investor, you need to show evidence to HMRC you’re a risk:
- The investment involves genuine risk.
- Funds will support business growth and development.
- There are no arrangements to protect investors from risk.
4. Submit your application
Use HMRC’s online portal to apply, including a cover letter and all supporting documents.
5. Wait for a response
HMRC typically takes 15-40 working days to process applications.

Step 4: Secure investors
With Advance Assurance in hand, you can confidently approach potential investors. Leverage the tax relief benefits as a key selling point in your pitch.
- Target the Right Investors: Focus on investors or venture capitalists specialising in early-stage businesses.
- Communicate Clearly: When reaching out to investors, emphasise how SEIS/EIS tax reliefs reduce risk while maximising returns.
- Leverage Networks: Platforms like Seedrs or AngelList can connect you with potential investors looking for SEIS & EIS investment opportunities.
Tip: Use testimonials or case studies to demonstrate the potential of your business to past investors.
Step 5: Issue compliance certificates
Once you’ve secured funding, your next task is to issue compliance certificates (SEIS3 or EIS3) to your investors. These certificates enable them to claim their tax reliefs. The process is as follows:
- File a Compliance Statement (SEIS1/EIS1): Submit this to HMRC once you’ve spent at least 70% of the funds raised.
- Receive Authorisation: HMRC will review your submission and, if approved, issue a letter allowing you to distribute SEIS3/EIS3 certificates.
- Issue to Investors: Share the certificates promptly so investors can claim their relief.
Tip: Track deadlines closely to avoid delays in tax relief claims, which could impact investor confidence.
