Built for UK High Earners
If you earn between £100,000 and £150,000, you are one of the most overtaxed groups in the UK. The personal allowance taper creates a hidden 60% tax band that most people do not even know exists. Traditional accountants charge hundreds of pounds for advice that our tools deliver instantly.
We built Stop Losing Money to Tax because we saw this gap first-hand. High earners deserve the same quality of tax planning that ultra-high-net-worth individuals get from expensive advisors — without the price tag. Every feature is designed around the specific tax challenges that UK earners above £100k face.
