Understanding stocks and shares ISA fees
A stocks and shares ISA, or Individual Savings Account, allows UK investors to hold investments tax-free up to the annual allowance. The key to maximising returns lies in a thorough stocks and shares ISA fees comparison, as even small percentage differences can erode gains over time. For the 2025/26 tax year, the allowance stands at £20,000, but fees from platforms can significantly impact how much of that you keep.
Types of fees to watch
Platform fees, often a percentage of your portfolio value (typically 0.25% to 0.45%), cover account management and custody. Trading commissions apply per buy or sell, while dealing charges might add £5-£12 per trade. Hidden costs like foreign exchange fees for international shares or exit fees when switching providers can add up; always review the full terms.
How fees impact returns
Assuming a 5% annual return on a £10,000 investment, a 0.45% fee could cost £225 over five years, compared to just £125 at 0.25%. This compounding effect highlights why a stocks and shares ISA fees comparison UK is essential—lower fees directly boost net returns. According to data from money.co.uk, average fees range from 0.25% to 0.45%, with zero-fee options like Trading 212 preserving more of your growth.
UK tax year basics
The tax year runs from 6 April to 5 April, and your £20,000 allowance resets then. You can split it across ISAs, but fees apply per provider. For detailed rules, see the HMRC technical note on Individual Savings Accounts.
