Fintech Accounting & Tax Services in the UK
Build a compliant, audit-proof financial infrastructure. Specialized services for payments, lending, and digital asset companies in the UK.
Get a QuoteThe United Kingdom, and London in particular, stands as a global titan in the fintech industry. However, operating in this space means navigating one of the world's most stringent regulatory environments, overseen by the Financial Conduct Authority (FCA). For a UK fintech, the finance function is not a back-office task; it is a core, regulated part of the business. From handling client money under CASS rules to implementing robust anti-money laundering (AML) systems and undergoing mandatory annual audits, the financial and compliance burdens are immense. Standard accounting practices are completely inadequate. This guide covers the essential, highly specialized accounting services that UK fintech companies require to operate legally and build trust.
Who This Service Is For
Our UK fintech accounting services are designed for companies across this dynamic sector:
- E-Money Institutions (EMIs) & Payment Institutions (PIs): Companies that need to manage segregated client funds, safeguard capital, and report to the FCA.
- Lending Platforms: Peer-to-peer and direct lending businesses that must manage loan books, credit risk, and comply with consumer credit regulations.
- Digital Wealth Managers & Robo-Advisors: Platforms handling client investments that must adhere to strict FCA rules on asset custody and reporting.
- Cryptocurrency Exchanges & Custodians: Companies in the digital asset space needing to comply with the UK's crypto-asset registration and AML requirements.
- Reg-Tech & Sup-Tech Providers: Companies building compliance solutions who must themselves demonstrate exemplary financial controls to their clients and regulators.
When It Is Required
Specialized fintech accounting is required from the moment you decide to pursue a regulated activity. It is not something that can be added later. It becomes critical at these key stages:
- During FCA Application: Your application for authorisation must include detailed financial projections and a comprehensive description of your compliance and control framework.
- When Handling Client Money: The moment you hold or control client funds, you fall under the CASS (Client Assets Sourcebook) rules, which require daily reconciliations and reporting.
- Before Your First Financial Audit: UK fintechs are subject to mandatory annual audits. Preparing for this requires months of work and an audit-proof set of books from day one.
- During a Fundraising Round: Investors in the fintech space conduct deep due diligence on your regulatory compliance and financial controls. Any weakness can kill a deal.
Cost Ranges in the UK
The cost of fintech accounting reflects the high level of expertise, risk, and regulatory engagement required.
- Early-Stage Fintech (Pre-authorisation): £2,500 - £6,000 per month. This covers building the financial models for application, setting up the compliant chart of accounts, and initial policy drafting.
- Authorised Growth-Stage Fintech: £6,000 - £15,000+ per month. This involves a dedicated team for daily reconciliations, CASS reporting, management accounts, and ongoing audit and regulatory liaison.
- Virtual CFO for UK Fintech: Often integrated into higher-tier services, this provides strategic guidance on regulatory capital, risk management, and board-level reporting.
Compliance Risks
In the UK fintech market, compliance failures are existential threats.
- FCA Enforcement Action: The FCA can impose enormous fines, restrict business activities, or revoke authorisation entirely for breaches of its rules, effectively shutting down the company.
- CASS Breaches: Failure to properly segregate and protect client money is one of the most serious offenses and can lead to severe penalties and reputational ruin.
- AML Failures: Weak anti-money laundering controls can result in massive fines and, in serious cases, criminal prosecution of directors under the Proceeds of Crime Act.
- Failed Audits: A qualified audit opinion can trigger regulatory investigation and destroy the trust of investors, banking partners, and customers.
Why Outsourcing Works Better
