The MTD Challenge

Making Tax Digital (2026) requires granular accuracy. Manual auditing of CSV exports from messy client software is the #1 bottleneck for UK firms.

The Fincheck Solution

Upload your raw data. Our engine validates math, checks VAT rates (20%, 5%, 0%), and highlights errors instantly. You only review what's broken.

🛡️ Privacy-First Architecture

Zero-Storage Policy— your client data is processed in a secure in-memory buffer and never written to disk. No permanent storage. Fully GDPR & MTD compliant.

Behind the Code

I built Fincheck.uk because I saw the manual overhead accountants face every quarter. My goal is to bridge the gap between messy data and HMRC-ready accuracy — without compromising client privacy.
