Raising investment in the competitive smart-home technology sector requires more than a promising idea. Investors now look for tax-efficient opportunities backed by compliant structures. The Seed Enterprise Investment Scheme (SEIS) and Enterprise Investment Scheme (EIS) offer generous tax reliefs that make your start-up significantly more attractive to early-stage and growth investors. At Apex Accountants, we support smart-home start-ups across the UK with expert tax advice, business structuring, and investment readiness. Our team ensures founders meet HMRC’s technical conditions while preserving long-term growth flexibility. This article outlines how to prepare for EIS and SEIS for smart-home tech start-ups in 2026. Use the checklist to align your business with HMRC rules, secure investor interest, and avoid disqualification pitfalls.
Steps to Qualify for EIS and SEIS Funding
Smart‑home tech start‑ups must meet several eligibility rules to benefit from SEIS and EIS schemes for smart-home start-ups. The following steps outline the key requirements HMRC expects before approving your company for investor tax relief.
Choose the right scheme for your stage
SEIS is ideal for pre-revenue or very early-stage companies. Your company must have fewer than 25 full-time employees and under £350,000 in gross assets. It must be less than 3 years old. EIS suits more developed businesses, with up to 250 employees and assets under £15 million. The company must be within 7 years of its first commercial sale (or 10 years if classed as knowledge-intensive). Many smart-home tech start-ups begin with SEIS and follow with an EIS round as they scale.
Confirm your trade qualifies
Your core business must involve developing, producing, or supplying smart-home products or technology. HMRC excludes trades like leasing, financial services, and property development. If these activities constitute more than 20% of your business, you may lose your eligibility. Focusing on innovation helps meet SEIS rules for early-stage tech companies, particularly when building devices that use automation, AI, or IoT applications.
Prove there’s real investment risk
HMRC requires genuine capital risk. Prepare a detailed business plan and financial forecasts. Show that the money raised will be used for product development, recruitment, software upgrades, or marketing. Do not offer capital protection, guaranteed returns, or exit rights. Your business must grow and generate income — not just preserve capital.
Request Advance Assurance
Advance Assurance from HMRC improves investor confidence by indicating your company is likely to meet eligibility requirements. To apply, submit detailed forecasts, a business plan, the share structure, and how you intend to use the funds. Your ordinary shares must carry no preferential rights. Clearly show how your smart-home product fits a market demand and aligns with the objectives of SEIS and EIS schemes for smart-home start-ups.
Spend correctly and report on time
All funds raised under SEIS or EIS must be spent on qualifying activities within 3 years (SEIS) or 2 years (EIS). Track where funds go. Acceptable costs include salaries for R&D staff, IP protection, testing, and equipment. Avoid spending on shares, acquisitions, or debt repayment. Please ensure that you file your SEIS/EIS1 forms with HMRC following the share issue and maintain proper records in accordance with SEIS rules for early-stage tech companies.
Stay compliant for at least three years
Your business must maintain compliance for at least three years after issuing shares. Don’t change your trade, restructure ownership, or issue preferential shares. Keep HMRC updated if anything changes. If your company breaks the rules, HMRC could withdraw the investors’ tax relief.
