About TaxWhizz.ai
We believe everyone deserves access to professional-grade tax intelligence. Our AI-powered platform replaces traditional accounting services with precision technology — faster, more accurate, and available 24/7.
Founded in 2026
TaxWhizz.ai was born from a simple observation: the UK accountancy industry, worth over £10 billion, still relies on manual processes, spreadsheets, and hourly billing. While every other financial service has been transformed by technology, tax advisory remained stubbornly analogue.
Our founding team — combining decades of Big 4 tax experience with cutting-edge AI expertise — set out to build the accounting firm of the future. Not a tool that helps accountants work slightly faster, but a platform that replaces the entire traditional model with something fundamentally better.
Today, TaxWhizz.ai processes over 1.2 million tax calculations, serves thousands of firms and individuals, and delivers results with 99.97% accuracy — all at a fraction of the cost of traditional accounting services.
