Syntax Ai Limited secures £252k for tax automation platform

Accounting firms can automate tax compliance and risk checks using a platform developed by Syntax Ai Limited. Based in Burton-On-Trent, the company has secured an estimated £252k in its latest funding round. The technology encodes UK tax legislation into an expert system, allowing users to integrate client data for automated planning and return reviews.

The business was incorporated in February 2025 to reduce manual effort in the tax sector by detecting errors and uncovering relief opportunities. These features are designed to increase advisory revenue for professional services firms. This recent capital injection follows a total of £532k raised during its first year of operation.

According to accounts for the year ended 31 December 2025, the firm employed four people. Documentation for the current investment was filed in April 2026 (with an allotment date in the same month).
