Adult Stocks & Shares ISA

A tax-efficient way to invest and grow your wealth, offering flexibility, control, and long-term benefits.

In this guide, discover:

  • How a Stocks & Shares ISA works and the benefits it offers.
  • The tax advantages and flexibility of a Flexible ISA.
  • Who can open one and how to make the most of your allowance.
  • Key considerations before investing.

A Stocks & Shares ISA is a government-approved account that lets you invest in a wide range of assets, including shares, funds, bonds, and investment trusts, without paying UK Income Tax or Capital Gains Tax on your returns. For the 2025/26 tax year, you can invest up to £20,000, either as a lump sum or through regular contributions.

Unlike a Cash ISA, which works like a savings account, a Stocks & Shares ISA has the potential to generate higher returns over the long term, making it a powerful tool for building wealth. At Tacit, we focus on Flexible Stocks & Shares ISAs, which allow you to withdraw and replace funds within the same tax year without losing your annual allowance.

Key Benefits:

  • Tax efficiency: All income, growth, and capital gains are free from UK tax.
  • Flexibility: Withdraw and replace funds in the same tax year with a Flexible ISA.
  • Control: Choose how your money is invested and when to access it.

While a Stocks & Shares ISA can be a valuable part of your financial plan, it may not suit everyone. Market investments can go down as well as up, and you could get back less than you invest. Always consider your goals, risk tolerance, and time horizon.

Our ISA service is managed in partnership with AJ Bell Securities Ltd, ensuring secure custody of assets while we focus on delivering your investment strategy.
