Why Filabl

Not just another accounting app

Built from scratch for UK tax — not retrofitted from US software. Direct HMRC API. AI that knows PAYE from CT600. At a fraction of what you'd pay an accountant.

The old way
Traditional accountants & generic software

Expensive, slow, and not built for UK tax.

  • £200–£500/month for a human accountant
  • Wait days or weeks for tax advice
  • Manual CSV exports and HMRC gateway uploads
  • Year-end tax bill surprises
  • US-built software retrofitted for UK rules
  • Lock-in contracts and expensive exit fees
The Filabl way
AI-powered. MTD connected. UK-first.

Everything you need, built specifically for HMRC.

  • From £19/month — or free forever on Basic
  • AI answers in seconds, 24/7 — no waiting
  • Files VAT, CT600, SA100 & RTI directly via MTD API
