Accountancy is data- and document-heavy, with growing client volumes under Making Tax Digital — strong AI territory, with clear professional guardrails. Here’s how UK firms can adopt AI in 2026. (dgm implements osFoundry as an independent partner; professional responsibility stays with the firm.)
Where AI helps
- bookkeeping and data entry;
- document and invoice processing;
- drafting and client correspondence;
- research; and
- workflow management across growing client volumes.
AI handles repetitive work so accountants focus on advice and judgement.
ICAEW guidance
ICAEW provides extensive AI guidance for members, emphasising:
- transparency about AI use;
- not over-relying on AI outputs;
- understanding limitations — especially correct application of current UK tax rules, thresholds and reliefs; and
- protecting client data.
The key transition point is governance: who’s accountable, where AI may be used, how outputs are reviewed. PCRT (Professional Conduct in Relation to Taxation) applies the five fundamental principles through an AI lens for tax work.
Making Tax Digital is a driver
Making Tax Digital increases reporting frequency and client touchpoints, pushing firms toward scalable workflow automation — exactly where AI helps with data processing and routine tasks.
The two big risks
- Client data in uncontrolled AI — ICAEW flags uploading identifiable client data into public systems as a serious data-protection risk.
- Over-reliance — AI may misapply current UK tax rules.
Both are managed by a governed, data-controlled platform and human review.
Where osFoundry and dgm fit
dgm builds data-controlled AI on osFoundry: client data stays in your control (self-hosting or an EU region — it publishes US/EU/JP regions, not a UK one), bring-your-own-key so data isn’t sent to consumer tools, audit logging, and human review of outputs. That directly addresses ICAEW’s data and over-reliance concerns.
dgm is an independent integration partner with zero integrations so far — no firm case studies to claim. Professional responsibility stays with the firm. To scope a compliant accountancy AI project, book a consultation with dgm. Not professional or tax advice.
