SEIS Accountants - HMRC Advance Assurance, SEIS1 Compliance and the Full SEIS Lifecycle
We file SEIS and EIS advance assurance, draft compliance statements, distribute investor certificates, and protect your three-year qualifying period. ACCA-regulated, scheme-experienced, UK-wide.
SEIS and EIS Focus
We file SEIS and EIS advance assurance, SEIS1 and EIS1 compliance statements, and SEIS3 or EIS3 investor certificates with HMRC as day-to-day work.
HMRC Venture Capital Reliefs
We work day-to-day with HMRC's Venture Capital Reliefs team, so we know the common follow-up queries on advance assurance and resolve them quickly.
Cap Table and Share Issuance
We structure founder, employee, and SEIS or EIS investor shares correctly at first issuance, including timing rules between SEIS and EIS within the same round.
Fixed Written Quotes
Every engagement starts with a fixed written quote based on your round and the scheme work involved. The price we quote is the price you pay, with no obligation.
SEIS and EIS Are Where Most Founders Get Burned
Most SEIS and EIS failures are not failures of underlying eligibility. They are failures of the application narrative, the share-issue sequencing, the SEIS1 reconciliation, or the qualifying-period monitoring. The schemes are entirely workable, but the documentation chain has to be right end-to-end, and the cost of getting any one step wrong is paid by your investors as a clawback notice from HMRC.
From pre-revenue SaaS startups in London to deeptech spinouts in Cambridge and consumer brands in Manchester, founders raising SEIS and EIS need accountants who do this work day-to-day with HMRC's Venture Capital Reliefs team. A generalist accountant who files three SEIS applications a year is not the same as a specialist who files three a week.
Our live caseload is dominated by SEIS and EIS work. We handle advance assurance applications, share issuance and cap table maintenance, SEIS1 and EIS1 compliance statements, investor certificate distribution, and three-year qualifying-period monitoring. We come back within 48 hours with a fixed written quote, with no obligation.

3 yrs
is the SEIS qualifying-period clock. Most clawback events happen because no one is monitoring it after the round closes.
Specialist caseload, not generalist.
Network practices file SEIS work weekly, not yearly.
Different Funding Stages Need Different SEIS Specialism
From first-time founders raising a £150k SEIS-only seed round to scaled startups doing combined SEIS-and-EIS series A closes, each stage needs targeted scheme expertise.
Pre-Revenue SaaS and Tech
First-time SEIS rounds with £100-200k typical raises, 3-6 angel investors, and pre-revenue valuations between £750k and £1.5m. We draft advance assurance against ARR-projection valuations, structure cap tables for follow-on rounds, and stage SEIS1 filings to coincide with investor tax-relief expectations.
First-Time Founders
Founders raising their first SEIS round with no prior HMRC scheme experience. We handle the full chain from pre-application eligibility review through advance assurance, share issuance, SEIS1 filing, and SEIS3 distribution, so the first investors see a clean process and come back for follow-on capital.
Combined SEIS-and-EIS Rounds
Where the round size exceeds the SEIS lifetime cap, the round needs sequenced SEIS-then-EIS share issuance, two compliance statements, and HMRC clearance work in parallel. We own the closing calendar so neither relief is broken by accidental same-day allotment.
Knowledge-Intensive Companies
Biotech, deeptech, and other R&D-intensive startups can claim KIC status to double their EIS limits and extend the commercial sale window from seven to ten years. We run the documentary qualification at advance assurance and unlock the extended caps.
Active Three-Year Qualifying Periods
Companies with one or more SEIS or EIS rounds inside their three-year qualifying windows need active monitoring of trade, asset, employee, and use-of-funds tests, plus transaction-by-transaction clearance for material events. The cost of a clawback to the investor base is severe; the cost of monitoring is small.
Series A and US Flip Decisions
Companies approaching series A face structural choices that interact with prior SEIS and EIS positions: knowledge-intensive EIS, share-for-share rollovers on acquisition, and the SEIS or EIS implications of a US flip. We model the routes before the deal closes.
The Full SEIS and EIS Lifecycle, Handled In-House
We handle every stage of the scheme work, from pre-application eligibility through three-year qualifying-period monitoring.
SEIS Advance Assurance
End-to-end SEIS advance assurance applications, from drafting the business activity narrative to handling HMRC's Venture Capital Reliefs team queries. The HMRC pre-approval that gives angel investors the confidence to commit to your seed round.
EIS Advance Assurance
EIS advance assurance for raises beyond the SEIS lifetime cap. Strategic guidance on the SEIS-to-EIS handover, asset and employee tests, and HMRC submissions for series A and beyond.
Share Issuance & Cap Table
Getting share classes, founder allocations, and SEIS or EIS investor shares right at first issuance. Investor-ready articles, board resolutions, Companies House filings, and the cap table maintenance that prevents HMRC clawback later.
SEIS1 & EIS1 Compliance Statements
The post-share-issue HMRC paperwork that turns a share issue into actual investor relief. SEIS1 and EIS1 compliance statements drafted, filed, and chased through to receipt of authorisation to issue investor certificates.
Investor Tax Certificates (SEIS3 / EIS3)
Issuing the SEIS3 and EIS3 investor certificates that unlock 50% (SEIS) or 30% (EIS) income tax relief on personal returns, plus the CGT exemption on a future qualifying exit. Bulk issuance, replacement certificates, and investor query handling.
Three-Year Qualifying Period Monitoring
The three years after share issue are when SEIS and EIS relief can be lost. Continuous monitoring of trade, asset, employee, control, and use-of-funds tests with HMRC clearance work for material changes, so a clawback never reaches your investors.
R&D Tax Credits
R&D tax credit claims under the merged scheme for SEIS and EIS-backed companies. Specialist narrative drafting, qualifying cost identification, and Advance Notification handling, structured around how SEIS and EIS interact with the R&D scheme.

SEIS and EIS Specialists Across the UK
The SEIS and EIS investor base is concentrated in London but the founders raising under the schemes are distributed across every UK tech and deeptech hub. From Cambridge biotech and Edinburgh fintech to Bristol creative-tech and Manchester SaaS, the founders we work with come from every corner of the UK ecosystem.
Wherever you are based, the SEIS and EIS qualifying conditions are identical and HMRC's Venture Capital Reliefs team is centralised, so the specialism is genuinely UK-national. We work fully remotely with founders across all four nations of the UK, so geography rarely constrains the engagement.

SEIS Specialist Coverage Across the UK
We work with founders throughout the UK, bringing the right scheme experience wherever your business is based.
Transparent SEIS and EIS Specialist Fees
We offer fixed-fee scheme work with clear pricing per round and per filing.
SEIS Advance Assurance
£750 – £2,000
Eligibility review, application drafting, HMRC submission, follow-up correspondence · Per application
Pricing varies with the complexity of the trade and the cap table. Borderline excluded-trades cases, prior-refusal resubmissions, and combined SEIS/EIS applications sit at the upper end. Most specialists fix the fee per application rather than charging hourly.
EIS Advance Assurance
£850 – £2,500
Eligibility review, KIC assessment if applicable, application drafting, HMRC submission, follow-up correspondence · Per application
EIS applications are typically priced slightly higher than SEIS because the risk-to-capital condition and the KIC assessment add scope. Where a SEIS file is already on record with HMRC, the EIS application can be fast-tracked at lower cost.
Share Issuance & Cap Table
£600 – £2,500
Articles audit, board minutes, subscription documentation, share certificates, SH01 Companies House filing, register of members · Per round
Pricing scales with round size and investor count. A simple SEIS round of 3-5 angels sits at the lower end; a combined SEIS plus EIS round with sequenced share issues and 20+ investors sits at the upper end. Ongoing cap table maintenance typically priced as an annual retainer.
SEIS1 / EIS1 Compliance
£500 – £1,500
Source data assembly, form drafting, reconciliation to accounts, HMRC submission, follow-up handling · Per round
Single SEIS1 or EIS1 filings are typically fixed-fee. Combined rounds requiring two compliance statements, or rounds with nominee-held shares requiring beneficial-owner schedules, sit at the upper end. Investor certificate distribution is included within the engagement.
Investor Tax Certificates
£200 – £750
Certificate distribution, covering communication, PDF retention, replacement-certificate handling · Per round
Most specialists include certificate distribution inside the SEIS1 or EIS1 engagement. Standalone certificate work (catch-up distributions, replacement requests, Crowdcube/Seedrs syndicate coordination) is priced at the upper end.
Three-Year Period Monitoring
£600 – £2,400
Annual qualifying-conditions review, transaction clearance, HMRC clearance applications, threshold tracking · Annual retainer
Most specialists offer this as an annual retainer that runs for the duration of the qualifying periods. Companies with multiple live SEIS or EIS rounds, active M&A discussions, or approaching threshold tests pay at the upper end.
R&D Tax Credit Claims
£1,500 – £8,000
Project scoping, technical narrative, cost schedule, Advance Notification, claim filing, enquiry support · Per claim period
Fees typically structured as a fixed fee or as a percentage of the credit obtained (10-20 percent in the merged scheme era, lower than the historical SME-scheme range). First-time claimants pay slightly more because the technical narrative has to be built from scratch.
Annual Retainers for Multi-Round Founders
We offer annual retainers that bundle the SEIS and EIS lifecycle work across a financial year, including qualifying-period monitoring on prior rounds.
Why Founders Work With Us
SEIS and EIS specialism is narrower than general startup accounting, and the cost of a generalist mistake is paid by your investors.
Scheme Work Is the Day Job
We keep a live caseload of SEIS and EIS work and deal directly with HMRC's Venture Capital Reliefs team, rather than filing the occasional application alongside general practice.
