How accurate is the extraction?

Typically 90-95% for digital PDFs, 80-90% for scanned documents. Always review the output before filing — the tool flags uncertain values.

Does it handle scanned/handwritten documents?

Yes, via Claude's vision capabilities, but accuracy is lower for poor scans or handwriting. The confidence column tells you what to double-check.

Overview

Accountants spend hours manually pulling numbers from tax documents. Claude Code builds a Node.js tool that reads PDF or image tax forms using Claude's vision capabilities, extracts key fields (gross pay, tax paid, NI, pension contributions), and outputs them into a structured CSV. Always review the output before filing — extraction accuracy is typically 90-95% for digital PDFs and 80-90% for scanned documents.

Target audience: Accountants, tax advisors, and bookkeepers processing UK tax documents
