Stocks and Shares ISA UK: The Complete 2026/27 Guide

You can shelter up to £20,000 a year inside a Stocks and Shares ISA in 2026/27, with zero tax on gains, dividends or interest.

Since April 2024 you can pay into more than one Stocks and Shares ISA in the same tax year, but the £20k cap still applies across all of them.

Pick a low-cost platform, hold globally diversified funds, and never withdraw money to move it. Always use the formal ISA transfer process.

A Stocks and Shares ISA is the single best wrapper most UK investors will ever own. Use it before you do anything fancy.
