ISAs are NOT tax efficient for dentists
ISAs are NOT tax efficient for dentists
It’s not just about where you invest, it’s about how efficiently you get the money there in the first place.
April 2, 2026

Most dentists assume maxing out their ISA is a no-brainer…

But what if that advice is actually costing you thousands in unnecessary tax?

In this conversation, Ross and David Abel discuss:

  • Why pulling money out of your limited company to fund an ISA can trigger huge tax bills
  • How this can kill your compounding potential before you even start investing
  • Why “use it or lose it” ISA thinking isn’t always the smartest move
  • How investing within your limited company can often be far more tax-efficient
  • The power of flexibility, drawing income later, when your tax rate may be lower
  • How this ties into retirement planning and intergenerational wealth

It’s not just about where you invest, it’s about how efficiently you get the money there in the first place. In many cases, taking a large tax hit just to fund an ISA can leave you worse off than keeping and investing funds inside your company.

This isn’t one-size-fits-all – the right strategy depends on your income, goals, and long-term plan.The best results come from a collaboration between your accountant and financial adviser – creating a strategy that’s tailored, tax-efficient, and built for long-term growth.
