PrompTax - Stocks and Options CGT tool

AI-powered UK Capital Gains Tax software for accountants

PrompTax turns messy broker statements into HMRC-ready Capital Gains Tax reports. Upload multi-broker, multi-currency PDFs or CSVs — AI extracts every trade so you verify the output, not retype it into a spreadsheet. Then it applies the full HMRC waterfall — Same-Day, 30-Day Bed & Breakfast (cross-year aware), Section 104 pooling — plus equity options rules (S144/S148) most CGT tools can't touch. Out comes an SA108-ready PDF with a full audit trail and SHA-256 tamper-evident verification.

Hey everyone — I'm the builder behind PrompTax. I built this because every UK accountant I spoke to was still doing Capital Gains Tax by hand in spreadsheets. HMRC's same-day, 30-day bed & breakfast, and Section 104 pooling rules are brutal to apply correctly at volume, and one missed cross-year 30-day match can silently corrupt a client's pool for years. PrompTax reads broker PDFs/CSVs with AI, has you verify the extracted trades, then applies every HMRC matching rule automatically — including options (S144/S148), which most CGT tools don't even attempt. It outputs an SA108-ready PDF with a full audit trail, cryptographically hashed so it's tamper-evident. It's in free private beta for UK accounting practices right now, no card required. I'd love feedback from anyone who deals with CGT professionally — or anyone who just wants to poke holes in it. Ask me anything below!
