Why SEIS & EIS Compliance Matters
HMRC’s SEIS and EIS schemes offer up to 50% and 30% income tax relief respectively. But relief isn’t automatic. You need to file the compliance statement—Form SEIS1 or EIS1—accurately and on time. Mess it up, and investors lose certificates (SEIS3/EIS3) and their tax relief. That’s reputational damage you simply can’t afford.
Most founders get advance assurance sorted early. But the real test is the compliance statement. It confirms:
– Shares issued align with scheme rules
– Funds raised fuel eligible business activity
– Your company still fits the criteria
Once approved, you can issue tax certificates and let investors claim relief. It’s the final gatekeeper. Master this SEIS investment guide, and you’ll win trust, free up funds for growth and boost your credibility.
SEIS vs EIS: Filing Timelines and Thresholds
SEIS Key Dates
- Wait 4 months trading or spend 70% of SEIS funds on qualifying activities
- File Form SEIS1 within two years of the later of:
- End of the tax year shares were issued
- The 4-month milestone
EIS Key Dates
- Conduct qualifying trade for at least 4 months
- File Form EIS1 under the same two-year window
Tip: Issue all SEIS shares on one date and EIS shares on another. Splitting tranches means multiple filings—and higher costs.
What Goes Into Your Compliance Statement?
Your SEIS1/EIS1 needs to mirror every earlier submission:
– Company details (UTR, Companies House number, contact info)
– Share issue info (dates, classes, numbers, price paid matching SH01 filings)
– Use of funds (invoices, contracts, R&D spend)
– Business activities description (avoid excluded sectors)
– Eligibility proof (age, employee headcount, gross assets)
– Supporting docs (articles of association, board minutes, subscription agreements, cap table)
– Investor details (names, amounts subscribed, shares received)
Gather everything in one folder. Cross-check numbers. That way you avoid mismatches that stall or sink your compliance.
Common Pitfalls (and How to Dodge Them)
- Filing too early
Submitting SEIS1 before you hit 4 months or 70% spend? HMRC will bounce it. - Mismatched figures
SH01 forms versus compliance statement not lining up. Triple-check every figure. - Wrong share classes
Avoid preference or redeemable shares—only full-risk ordinary shares qualify. - Missed sequencing
SEIS shares must precede EIS shares. One mess-up and relief is refused. - Late filings
Miss the two-year deadline? Investors lose relief forever.
OnTheGo Accountants vs Oriel IPO: A Clearer Path
OnTheGo Accountants offer thorough SEIS/EIS compliance services. They’re experts in paperwork, with turnaround times as quick as 2–4 weeks when well prepared. But their model is service-based: you pay by the hour or project, which can add up if you have multiple share issues.

- Commission-free model: no per-filing fees. You pay a transparent subscription, so multiple compliance statements don’t blow your budget.

- Educational resources: guides, webinars and expert insights walk you through each step so you file correctly first time.
- Centralised dashboard: track share issues, compliance milestones and investor certificates in one place.
With Oriel IPO, you still get top-notch compliance support, but within a platform designed for founders and investors alike. No surprises. No unexpected costs.

FAQs on SEIS & EIS Compliance
Q: What’s the difference between advance assurance and the compliance statement?
Advance assurance is HMRC’s green light before you issue shares. The compliance statement (SEIS1/EIS1) is proof you met the conditions post-issue. Both are mandatory for investors to get tax relief.
Q: Can I file SEIS and EIS together?
No. You need separate compliance statements and must issue SEIS shares before EIS.
Q: How long does HMRC take?
Officially 6–8 weeks, but well-prepared submissions can clear in 2–4 weeks.
Q: What if I miss the two-year deadline?
There’s no extension. Investors lose their relief permanently.
