Building £95,000 in ISAs

The annual ISA allowance is £20,000, so reaching a £95,000 ISA balance takes at least 5 tax years of maximum contributions (excluding growth). Here is a suggested approach:

  • Maximise each year — Contribute £20,000 before 5 April each tax year
  • Invest early — Contributing at the start of the tax year gives more time for compound growth
  • Consider your mix — Cash ISAs for short-term needs, Stocks & Shares ISAs for long-term growth
  • Transfer old ISAs — You can transfer previous years' ISAs between providers without affecting this year's allowance
