A fintech accountant handles the finance work generic accountants get wrong: FCA safeguarding reconciliations, CASS 15 audit readiness, revenue recognition for payments flows, R&D tax relief for regulated software, and SEIS/EIS eligibility where “financial activities” exclusions apply. AccTek works with UK fintech startups from incorporation through FCA authorisation to Series A — combining cloud accounting on Xero with specialist knowledge of the rules that apply only to firms handling other people’s money.
Why fintech startups outgrow generic accountants
Most accountants can file your Corporation Tax return. Few can tell you whether your safeguarding reconciliation will survive an FCA audit — or whether your lending product just disqualified you from EIS.
Regulatory accounting is different
Customer funds aren’t your revenue. Safeguarded balances, agent flows and FX positions need books that separate client money from company money cleanly — from day one, not retrofitted at authorisation.
Your tax reliefs have trapdoors
SEIS and EIS exclude certain financial activities, and fintech R&D claims draw HMRC attention. Getting either wrong is expensive after the fact.
Investors expect regulated-grade reporting
VCs backing fintech look for evidence you can operate under supervision: clean management accounts, documented controls, and runway you can defend.
FCA safeguarding audit readiness under CASS 15
From 7 May 2026, the FCA’s Supplementary Regime (CASS 15) requires authorised payment and e-money institutions to perform daily safeguarding reconciliations, submit monthly returns, maintain a resolution pack, and undergo an annual safeguarding audit — unless the firm has held under £100,000 in relevant funds over a continuous 53-week period. The first audit report is due within six months of the firm’s first relevant period end.
What AccTek does:
- Design daily internal and external reconciliation processes that meet CASS 15 record-keeping rules
- Build your books so relevant funds, fees and own funds are separable on demand
- Prepare resolution pack documentation and monthly reporting (REP027) workflows
- Run a pre-audit gap analysis so your first safeguarding audit isn’t your first look at the rules — start with the CASS 15 readiness checklist
For the full rules — scope, the £100,000 exemption and deadlines — see our FCA safeguarding audit requirements guide.
R&D tax relief for fintech companies
Fintech development work — payments infrastructure, fraud detection, ledger engines, API platforms — frequently qualifies for R&D tax relief under the merged R&D scheme, which pays a 20% expenditure credit on qualifying costs for 2026/27. Loss-making, R&D-intensive startups may qualify for enhanced support. HMRC scrutinises software claims closely, so the technical narrative matters as much as the numbers.
- Qualifying cost identification: staff, subcontractors, cloud computing and data costs
- Technical narratives written to HMRC’s software guidance, not boilerplate
- Enquiry defence: documentation built claim-by-claim, before HMRC asks
- Grant interaction: how Innovate UK or other subsidies affect your claim
For what qualifies in fintech specifically — and the six-month notification trap — see our R&D tax relief for fintech guide. Start with our R&D tax relief service for startups or run your numbers through the R&D tax credit calculator.
SEIS and EIS for fintech — do you qualify?
It depends on your trade. Banking, insurance, money-lending, debt factoring, hire-purchase financing and other financial activities are excluded from SEIS and EIS. A fintech whose trade is lending is likely excluded; a fintech selling software to financial institutions generally qualifies. For 2026/27, SEIS offers investors 50% income tax relief (£250,000 company lifetime limit) and EIS offers 30% relief. Because fintech sits close to the exclusion line, HMRC advance assurance before raising is essential.
AccTek prepares and submits advance assurance applications with the trade analysis HMRC needs to see — so the excluded-activities question is answered before your investors ask it. For the full analysis by business model, see our SEIS and EIS for fintech guide, then our SEIS advance assurance service and the SEIS/EIS tax relief calculator.

Fintech accountant FAQs
Does my fintech startup need an FCA safeguarding audit?
If your firm is an authorised payment or e-money institution, an annual safeguarding audit is required under the FCA rules in force from 7 May 2026, unless you have held less than £100,000 in relevant funds over a continuous period of at least 53 weeks. Senior management must reassess the exemption on an ongoing basis. This is general information, not advice on your firm's specific position — AccTek can review your safeguarding arrangements and audit readiness.
Do fintech companies qualify for SEIS or EIS?
Many do, but not all. SEIS and EIS exclude trades consisting substantially of financial activities such as banking, insurance and money-lending. Fintechs selling software or technology services generally qualify; fintechs whose income comes from lending or underwriting generally do not. HMRC advance assurance is the reliable way to confirm your position before raising.
Can fintech startups claim R&D tax relief?
Yes — genuine technological development in payments, fraud detection, data infrastructure and platform engineering can qualify under the merged R&D scheme for 2026/27. Routine integration or configuration does not. HMRC reviews software claims closely, so a robust technical narrative is essential.
What does a fintech accountant do that a general accountant doesn't?
Beyond accounts and tax, a fintech accountant handles safeguarding reconciliations, client money separation, partial exemption VAT, FCA reporting readiness, and the SEIS/EIS and R&D questions specific to regulated technology businesses.
Which accounting software do you recommend for fintech startups?
Xero, configured with a chart of accounts that keeps safeguarded client funds, fee income and own funds separable. AccTek is cloud-first and works with Xero, QuickBooks, Sage and FreeAgent.
