The Interactive Brokers ISA (IBKR ISA) seems to be a solid option if you seek an easy and inexpensive way to trade in stocks, funds, and other assets through a tax-free investment wrapper. There have been some tweaks as we progress through 2025 which we will cover shortly. This guide brings you updated facts, pricing, and features so that you can determine if it is the right ISA for you.
What is the Interactive Brokers ISA?
IBKR ISA is a Stocks and Shares ISA offered by Interactive Brokers, one of the leading low-cost brokerage firms frequently used by day traders and long-term investors alike. It enables UK residents to invest up to £20,000 per annum (2024/2025 allowance) without worrying about capital gains or dividend taxes.
Interactive Brokers unlike some UK-focused platforms allows its users access to global markets including but not limited to US and European stocks, Asian stocks, ETFs, and bonds. This feature makes it an excellent option for investors looking for diversification beyond the UK.

Is It Worth It In 2025?
For global investors who are cost mindful, the Interactive Brokers ISA is still an excellent choice. It remains a strong contender with lower fees for smaller portfolios and faster transfers, as well as improved app functionalities—especially if you trade often, are interested in international markets, or just want to unlock your full trading potential.
But if you only invest in UK funds, or prefer a more straightforward user interface, then AJ Bell or Fidelity would likely be better for you.
