What is SEIS and EIS Tax Relief?
The Seed Enterprise Investment Scheme (SEIS) and the Enterprise Investment Scheme (EIS) are government programs that help startups get funding. They also provide tax benefits for investors. These schemes make it easier for people to invest in new businesses by lowering financial risks and increasing potential returns.
What is SEIS?
The Seed Enterprise Investment Scheme (SEIS) helps new businesses in the UK get funding. It lets startups raise up to £250,000 from investors and provides attractive tax benefits, including:
- 50% income tax relief on SEIS investments
- No Capital Gains Tax (CGT) on profits from SEIS shares
- Loss relief to minimise risk if the business doesn’t succeed
What is EIS?
The Enterprise Investment Scheme (EIS) helps growing businesses that need more money. Companies can raise up to £5 million each year, with a total limit of £12 million. Investors gain advantages from this scheme:
- 30% income tax relief on EIS investments
- CGT deferral when reinvesting profits into an EIS-qualifying business
- Inheritance tax relief after two years of holding shares
Benefits of SEIS and EIS for Startups and Investors
The SEIS and EIS tax relief schemes offer great financial benefits for startups and investors in London. They are important for business growth and making investments safer. These schemes lower financial risks and promote early-stage funding, helping small businesses succeed.

Easier Access to Investment
Investors feel safer funding startups because of the tax relief, which lowers their risk.

Funding Limits
Startups can get up to £250,000 from SEIS and £5 million from EIS to grow their operations.

No Repayment Needed
SEIS and EIS investments don’t require repayment like loans do, so businesses can reinvest in their growth.

Common SEIS and EIS Compliance Mistakes Businesses Make
Many startups accidentally break SEIS and EIS rules, which can cause investors to lose tax relief. Here are the most common mistakes:
- Not Meeting Eligibility Criteria: Businesses must always meet SEIS/EIS conditions, including trading activities, employee limits, and share types. Changes in company status can affect eligibility.
- Issuing Incorrect Shares: SEIS/EIS shares must be ordinary shares without special rights. Issuing preference or convertible shares can disqualify the company.
- Using Funds Incorrectly: SEIS and EIS funds should be spent on qualifying activities like innovation, development, and job creation. Using funds for non-qualifying purposes, such as paying off debt or buying assets, can invalidate tax relief.
- Missing HMRC Filing Deadlines: Businesses need to submit compliance statements (SEIS1/EIS1 forms) on time. Delays or mistakes in paperwork can postpone or cancel tax relief.
- Failing to Hold Shares Long Enough: Investors must hold SEIS/EIS shares for at least three years to keep their tax relief. Selling or transferring shares too soon will result in losing tax benefits.
- Overlooking Annual Compliance Requirements: SEIS and EIS require ongoing compliance with HMRC rules. Not reporting changes or failing to submit required documents can lead to losing investor tax relief.
At Clarkwell, we simplify SEIS and EIS compliance, helping your business meet HMRC rules and gain investor trust.
- Ongoing Monitoring: We track your company’s status, finances, and share structure to ensure you stay compliant.

Step-by-Step Guidance on Applying for SEIS/EIS Tax Relief
We have a clear and effective method to help businesses meet SEIS/EIS requirements and get approved fast.
Step 1: Business Eligibility Assessment
We begin by reviewing your business to confirm it meets SEIS and EIS requirements. This includes checking:
- Your company’s trading activities and incorporation date.
- Employee count and asset value to confirm eligibility.
- Whether your planned use of investment funds complies with HMRC regulations.
Step 2: Preparation of SEIS/EIS Business Plan
A good business plan helps you get approval. We create a clear SEIS/EIS-approved business plan that shows:
- The company’s growth potential and financial forecasts.
- Compliance with SEIS/EIS funding requirements.
- Key details to attract potential investors.
Step 3: Advance Assurance Application
Before issuing shares, get Advance Assurance from HMRC. This confirms to investors that your company qualifies for SEIS/EIS tax relief. We:
- Prepare and submit the Advance Assurance application with supporting documents.
- Communicate directly with HMRC to address any queries.
- Help improve approval chances by ensuring compliance with strict HMRC guidelines.
Step 4: Share Issuance & Investment Compliance
Once Advance Assurance is approved, businesses can begin offering SEIS/EIS-eligible shares to investors. We make sure:
- Shares meet HMRC’s SEIS/EIS qualification rules.
- Proper share allotment and filings with Companies House.
- Full compliance to prevent tax relief disqualification.
Step 5: SEIS/EIS Compliance Statement Submission
After issuing shares and receiving investments, we submit the SEIS1/EIS1 compliance statement to HMRC. This confirms that your company meets SEIS/EIS requirements, allowing investors to claim tax relief.
Step 6: Issuing SEIS3/EIS3 Certificates to Investors
After HMRC approves the compliance statement, we help issue SEIS3/EIS3 certificates to investors so they can claim their tax relief benefits.

Step-by-Step Guide to Claiming SEIS and EIS Tax Relief
For Businesses: How to Apply for SEIS and EIS Approval
If you’re a startup looking to raise funds through SEIS or EIS, follow these steps:
Step 1: Create a Business Plan for SEIS/EIS
Your business needs a clear plan focused on growth that meets SEIS/EIS funding rules. A strong plan attracts investors and follows HMRC guidelines.
Step 2: Get Advance Assurance from HMRC
Before raising money, apply for Advance Assurance. This shows potential investors that your company qualifies for SEIS or EIS, boosting their confidence and improving your chances of getting funds.
Step 3: Issue SEIS/EIS Shares to Investors
After approval, you can give shares to eligible investors under SEIS/EIS rules. These shares must meet certain criteria for investors to get tax relief.
Step 4: Submit a Compliance Statement (SEIS1 or EIS1 Form)
After issuing shares, complete and send the SEIS1 or EIS1 compliance statement to HMRC. This certifies that your business meets the program requirements.
Step 5: Provide SEIS/EIS Certificates to Investors
Once HMRC approves the compliance statement, give SEIS3 or EIS3 certificates to investors. They need these certificates to claim their tax relief.
For Investors: How to Claim SEIS/EIS Tax Relief
Investors who fund SEIS/EIS-approved startups can claim tax relief by following these steps:
Step 1: Check Investment Eligibility for SEIS/EIS
Investors should verify that the startup has Advance Assurance from HMRC and that the investment qualifies for SEIS/EIS.
Step 2: Get SEIS3 or EIS3 Certificate from the Company
The startup must provide the investor with an SEIS3 or EIS3 certificate. This certificate is essential for claiming tax relief.
Step 3: Claim SEIS/EIS Tax Relief Through Self-Assessment
Investors can claim tax relief by filling out their Self-Assessment tax return and submitting the SEIS3/EIS3 certificate details to HMRC.
Step 4: Claim Capital Gains Tax Exemptions and Loss Relief
If eligible, investors can defer Capital Gains Tax on reinvested gains, apply for inheritance tax relief, and claim loss relief if the business fails.

Frequently Asked Questions (FAQs) About SEIS and EIS Tax Relief
1. How can I ensure my SEIS or EIS application gets approved by HMRC?
To get SEIS/EIS approval, your business must meet all HMRC eligibility requirements and follow a clear application process. Here are key factors that can improve your chances of approval:
- Create a clear business plan that shows strong growth potential.
- Use funds wisely; they should support business growth, not pay off loans.
- Make sure all company shares meet SEIS/EIS rules (only ordinary shares, no preference shares).
- Apply for Advance Assurance to check eligibility before issuing shares.
- After issuing shares, send a detailed compliance statement (SEIS1/EIS1) to HMRC.
At Clarkwell, we ensure every application is error-free and fully compliant to maximise approval chances.
2. What are the biggest reasons SEIS/EIS applications get rejected?
Common reasons for SEIS/EIS rejection include:
- Ineligible business activities: HMRC does not allow industries like property development, finance, and legal services.
- Incorrect share issuance: Issuing preference shares, convertible shares, or shares with voting limits disqualifies the company.
- Non-compliant use of funds: Funds must be used for business growth, not for paying off debts or dividends.
- Late or incorrect filings: SEIS/EIS compliance forms (SEIS1/EIS1) must be submitted correctly and on time.
- Failure to meet the three-year holding rule: If shares are sold or the company becomes ineligible within three years, tax relief is lost.
Our SEIS and EIS experts in London do a complete compliance review before submission to reduce these risks.
3. What happens if my SEIS/EIS application is rejected? Can I reapply?
You can reapply, but first, fix the problems that caused your rejection. HMRC usually gives feedback, which we use to improve your application and resubmit it successfully. If needed, we can:
- Modify your business structure to meet SEIS/EIS eligibility.
- Correct share allotments and ensure compliance with HMRC guidelines.
- Reapply for Advance Assurance, ensuring a stronger application.
4. Can I raise SEIS and EIS investment at the same time?
Yes, but you must raise SEIS first. If a company offers both SEIS and EIS shares in the same round, it must fully allocate SEIS-eligible shares before EIS shares. If this is not done correctly, investors may lose their SEIS tax relief.
5. How do I prove to investors that my business qualifies for SEIS/EIS?
Investors like companies that have Advance Assurance from HMRC. This assurance confirms that the company is eligible for SEIS/EIS before they invest. Our Advance Assurance service provides:
- HMRC pre-approval, reassuring investors.
- Detailed paperwork that aligns with SEIS/EIS requirements.
- A faster, smoother investment process.
6. Can I use SEIS/EIS investment to pay salaries?
Yes, but only if the salaries are fair and linked to business growth. HMRC will disqualify businesses that use SEIS/EIS funds mainly for high director salaries or unrelated costs.
7. Can investors get tax relief if they invest through a holding company?
SEIS/EIS tax relief is only for individual investors. Holding companies, trusts, or other corporate entities cannot claim this relief.
8. Do I need to issue new shares to qualify for SEIS or EIS?
Only newly issued shares qualify for SEIS/EIS. Existing shares, share buybacks, and purchases on the secondary market do not qualify.
9. What happens if I don’t use SEIS/EIS investment correctly?
Misuse of SEIS/EIS funds (e.g., using funds for debt repayment) can result in:
- HMRC withdrawing tax relief for investors.
- Company disqualification from future SEIS/EIS funding.
- Penalties and tax liabilities for investors and the business.
To reduce these risks, our SEIS and EIS accountants in London offer complete support for funding compliance.
10. Can I apply for SEIS/EIS funding if I have already raised capital?
Yes, but the type of funding matters. SEIS/EIS applies only if:
- The business has not previously issued SEIS/EIS shares that exceeded the limits.
- The investment meets SEIS (£250,000 cap) or EIS (£5 million per year) limits.
- Prior funding was not raised in a way that disqualifies SEIS/EIS eligibility (e.g., venture capital rounds affecting control).
11. How do I handle SEIS/EIS compliance after receiving the investment?
Compliance doesn’t stop after funding. Businesses must:
- Submit SEIS1/EIS1 compliance statements to HMRC.
- Ensure funds are spent within three years on qualifying activities.
- Maintain detailed investor records.
- Avoid any disqualifying corporate actions (e.g., mergers affecting share structure).
Our yearly SEIS/EIS compliance service helps your business stay eligible and prevents losing tax benefits.
12. Can SEIS/EIS shares pay dividends?
SEIS/EIS shares cannot guarantee dividends. After the minimum three-year period, the company can choose whether to pay dividends in the future.
13. Can a foreign investor claim SEIS/EIS tax relief?
SEIS/EIS tax relief is only for UK taxpayers. Foreign investors who pay UK income tax might still qualify. Our advisors can help with other tax-efficient investment options.
14. How do I claim SEIS/EIS tax relief as an investor?
Investors need a SEIS3 or EIS3 certificate from the company. They can use this to claim tax relief by:
- Their Self-Assessment tax return.
- Submitting the SEIS3/EIS3 details to HMRC.
- Requesting a PAYE tax code adjustment for immediate tax relief.
15. How can Clarkwell help with SEIS/EIS applications and compliance?
At Clarkwell, we provide:
- Expert SEIS/EIS Support: We help you get faster approval from HMRC.
- Advance Assurance Applications: We give investors confidence before they invest.
- Compliance Management: We help you avoid expensive penalties from HMRC.
