Early-stage technology startups and e-commerce businesses in the UK can access several government-backed tax reliefs designed to reduce the cost of innovation, attract investment and support growth. The main schemes are the Seed Enterprise Investment Scheme (SEIS), Enterprise Investment Scheme (EIS), Research and Development (R&D) tax relief, the Patent Box regime and specific capital gains reliefs.
Each relief has strict qualification rules that change regularly. This guide outlines the core requirements, practical steps to assess eligibility and actions founders should take. Always verify the latest criteria on GOV.UK or with HMRC before proceeding.
Seed Enterprise Investment Scheme (SEIS)
The SEIS offers tax incentives to individual investors who buy new shares in very early-stage companies. For the company this can make it easier to raise seed capital. To qualify the company must be carrying on a qualifying trade, have a permanent establishment in the UK, and meet size and age limits that are published on GOV.UK.
Practical qualification steps
- Confirm the company is no more than two years old (or meets the trading start rules) and has gross assets below the current threshold.
- Ensure the trade is not in an excluded sector such as property development, banking or legal services.
- Prepare a detailed business plan and financial forecast showing how the funds will be used for growth within the permitted period.
- Submit an SEIS1 compliance statement to HMRC once shares are issued and the company meets all conditions.
- Keep records of all share certificates, investor details and use of funds for at least six years.
Founders should speak to an accountant early to model different investment amounts and understand how the relief interacts with other schemes.
Enterprise Investment Scheme (EIS)
EIS is aimed at slightly larger or more established early-stage companies than SEIS. It provides similar investor tax reliefs and can be used after SEIS funds are exhausted. The company must still carry on a qualifying trade, be unquoted at the time of investment and have a permanent establishment in the UK.
Practical qualification steps
- Check that the company has fewer than the maximum number of full-time employees allowed and gross assets below the published limit.
- Draft a clear investment memorandum that demonstrates how the money will be spent on growing the trade within the required timeframe.
- Apply for advance assurance from HMRC before raising funds; this is not mandatory but reduces the risk of later rejection.
- Issue shares and file the EIS1 form within the permitted window after the investment.
- Maintain evidence that the funds were used for qualifying business activities.
Review eligibility each time a new funding round is planned because rules on previous investments and trading activity can affect qualification.
Research and Development (R&D) Tax Relief
R&D tax relief allows companies to claim a tax credit or enhanced deduction for qualifying research and development expenditure. Both SMEs and larger companies can claim, although the rates and method differ. The relief is available whether the company is profitable or loss-making.
Practical qualification steps
- Identify projects that seek to resolve scientific or technological uncertainties that are not readily deducible by a competent professional in the field.
- Record staff time, software licences, consumables and subcontractor costs that directly relate to the R&D project.
- Write a technical report describing the uncertainty, the work undertaken and why it qualifies; this forms the basis of the claim.
- Calculate the enhanced expenditure and submit the claim as part of the Company Tax Return or as an amended return within the two-year deadline.
- Retain all underlying records for HMRC inspection.
An e-commerce startup that develops its own recommendation engine or logistics optimisation software may have qualifying activity; routine website updates usually do not.
Patent Box Regime
The Patent Box allows companies to apply a lower effective tax rate to profits that are derived from patented inventions or certain other intellectual property rights. The relief is elective and requires the company to own or exclusively licence the qualifying IP.
Practical qualification steps
- Confirm that the company owns a granted UK or European patent or meets the criteria for other qualifying IP rights.
- Calculate the proportion of trading profits that are attributable to the patented technology using the prescribed formula or streaming method.
- Elect into the Patent Box on the Company Tax Return for the relevant accounting period; the election is irrevocable for that period.
- Keep detailed records showing how income and costs are allocated to the qualifying IP.
- Review the relief each year because changes in product mix or patent status can affect the benefit.
Technology startups that develop proprietary software or hardware with patentable inventions should assess whether filing for a patent makes commercial sense before claiming.
Capital Gains Reliefs for Founders and Investors
Several capital gains tax reliefs can reduce or defer tax when founders or early investors dispose of shares. These include Business Asset Disposal Relief (formerly Entrepreneurs’ Relief), reinvestment relief under EIS and SEIS, and hold-over relief in certain circumstances.
Practical qualification steps
- For Business Asset Disposal Relief, ensure the individual has held qualifying shares for the required ownership period and that the company meets the trading test at the time of disposal.
- When reinvesting under EIS or SEIS, claim deferral of the gain by subscribing for new shares within the permitted window.
- Keep accurate records of acquisition cost, disposal proceeds and any relief claimed.
- Consider the interaction with income tax reliefs already received because some combinations restrict the amount of relief available.
- Take professional advice before a liquidity event to model the net tax position under current rules.
Founders should track their qualifying period of ownership from the moment they acquire shares.
Next steps and where to get help
Begin by reviewing the company’s activities against the latest GOV.UK guidance for each relief. Create a simple eligibility checklist and update it at each accounting period end. Engage an accountant or tax adviser familiar with technology and e-commerce businesses to help prepare claims and applications.
Companies House filings, HMRC registrations and timely submission of compliance statements are all critical. Late or incorrect paperwork can result in relief being denied. Founders should also maintain clear separation between personal and company expenditure and document all R&D projects contemporaneously.

Frequently asked questions
Can a new e-commerce startup claim both SEIS and R&D tax relief in the same year?
Yes, provided the company meets the separate qualifying conditions for each scheme. SEIS focuses on the age, size and nature of the trade while R&D looks at the specific projects that resolve technological uncertainty. Claims are made on different parts of the tax return but must be consistent in describing the business activities.
What records do I need to keep to support an R&D tax credit claim?
You should keep project notes describing the uncertainty, staff timesheets or cost allocations, invoices for software, materials and subcontractors, and a technical report explaining why the work qualifies. HMRC may ask to see these during a compliance check, sometimes years later.
Does obtaining a patent automatically qualify me for the Patent Box?
No. The company must own or exclusively licence a qualifying patent and then calculate the proportion of profits that arise from the patented invention. Simply holding a patent is not enough; you must elect into the regime and apply the correct profit attribution method.
When should a founder consider Business Asset Disposal Relief?
It becomes relevant when selling shares or the business after meeting the minimum ownership period and trading conditions. Planning early helps ensure the company remains a qualifying trading company throughout the ownership period and avoids actions that could disqualify the relief.
How do I check if my technology startup is eligible for EIS or SEIS?
Review the latest GOV.UK guidance on company age, employee numbers, gross assets, excluded trades and use of funds. Many founders request advance assurance from HMRC before raising investment to confirm eligibility and reduce investor risk.
