What Taxfiler Ltd. does

Taxfiler Ltd. (legal entity IRIS Capital Limited, operating as IRIS Software Group) is a UK-based provider of cloud tax and accounts software for accountancy practices, with its primary product IRIS Elements Tax positioned for small, medium, and large practices.

The product is sold in three tiers (Tax Essentials, Tax Professional, Tax Enterprise) with add-on modules including VAT Filer, Trust Tax, Cashbook, and Accounts Production, alongside third-party integrations with KashFlow, Xero, and QuickBooks.

The business operates a hybrid SaaS revenue model: self-serve monthly/annual subscriptions for the Essentials and Professional tiers (with a free 30-day trial), and sales-led custom-quote engagements for the Enterprise tier. A £250/year Service Plan and bespoke Professional Services training provide incremental revenue. The firm operates in the UK only, has 1-10 employees per firmographic data (likely reflecting the Taxfiler-specific entity within the larger IRIS Software Group, which retains multiple subsidiaries and brands across HR, payroll, and education verticals).

Customers are predominantly UK accounting practices ranging from sole practitioners to multi-hundred-client firms, with named case studies including Eccounting Made Easy Ltd, Power Accountants, and individual practitioner Louisa Burton. The company has received industry recognition including a 2019 Cloud Excellence Award and 2023 UK IT Industry Awards. Leadership consists of James Reeves (Founder, CEO and Director). Strategic positioning emphasises regulatory compliance, ecosystem integration within the IRIS Elements platform, and AI-assisted error prevention as primary differentiation levers.

Recent moves6 records

Expansion highlights4 records

Direct peers

• TaxCalc: Direct UK tax compliance software rival targeting accountancy practices with HMRC-recognised personal and corporation tax products. Closest head-to-head competitor to IRIS Elements Tax in the UK practice tax software market.
• BTCSoftware: UK-based practice software provider offering tax, accounts production and bookkeeping tools to accountants. Comparable in target customer (accountancy practices), product scope (tax compliance) and UK regulatory orientation.
• FreeAgent: UK-focused cloud accounting solution (owned by NatWest) with strong uptake among UK accountants and micro practices. Comparable in targeting small UK accountancy practices and integrating tax compliance workflows.
• Capium: UK accountancy practice software suite covering bookkeeping, accounts production and tax submissions. Comparable as a UK practice-focused competitor selling MTD-compliant, HMRC-recognised tools with tiered pricing.

Broad incumbents

• Sage Group: UK-headquartered incumbent accounting and payroll software giant serving SMBs and practices. Overlaps with Taxfiler via Sage Tax and practice solutions, though it is a much broader platform spanning bookkeeping, payroll, HR and ERP.
• Xero: Global cloud accounting platform with a strong UK SMB/accountant base. Comparable because Taxfiler integrates with Xero, and many UK practices run Xero alongside IRIS Elements Tax for end-to-end tax workflows.
• Intuit QuickBooks: Cloud accounting platform with UK presence and accountant-facing products. Comparable via native integration into IRIS Elements Tax, addressing overlapping end-clients (UK SMBs) and competing for the same practice relationships.
• Wolters Kluwer CCH: Global tax and accounting compliance platform serving larger accountancy firms and corporates. Comparable in providing UK tax compliance, iXBRL and HMRC-submission tooling, though positioned upmarket relative to Taxfiler's SMB/mid-market focus.

Emerging players

• VT Software: UK practice-focused accounting and tax software vendor serving small accountancy firms. Overlaps with IRIS Elements Tax on customer segment (UK sole-practitioner / small practices) and product area (MTD-ready tax and accounts).
• Andica: UK-based cloud tax and accounts software aimed at accountants and small businesses. Comparable niche player with HMRC-recognised, MTD-aligned tax software targeting similar UK practice and SMB users.
