AI-powered UK tax platform 20 HMRC-accurate tools | TaxWhizz.ai

Hey Product Hunt! We built TaxWhizz because UK tax shouldn't require a degree in accounting. 4.3 million self-employed people in the UK file Self Assessment every year. Most are overpaying tax because they don't know what they can claim, miss deadlines because HMRC's systems are confusing, and pay £500-2,000/year for an accountant to do what should take minutes. TaxWhizz changes that. 20 HMRC-verified calculators using exact 2025/26 rates. AI chat that answers any UK tax question instantly. Upload an HMRC letter and we decode it into plain English with a template response. For accounting practices: complete CRM, workspaces, team roles, engagement tracking, branded reports, and integrations with Xero, QuickBooks, and HMRC MTD. We also just launched a free embeddable tax calculator widget — any website can add it with one line of code: https://taxwhizz.ai/widget/ Try it free at https://taxwhizz.ai — no credit card required.
