XTB offers a Flexible Stocks & Shares ISA and a Flexible Cash ISA.
A flexible ISA allows you to withdraw money and replace it within the same tax year without affecting your annual allowance.
XTB is also currently offering a limited time promotion. We are offering 6% AER (variable) to new XTB clients who opened an account between 1 March and 30 April 2026. The 6% AER includes a 2% boost for 90 days from the ISA open date.
After the boost ends, the rate reverts to our standard variable rate of 4% AER. Your ISAs must be opened before 30th April to qualify. Existing clients receive our standard variable rate of 4% AER for current or new ISAs.
