ISA Allowance Tracker UK | Calculate Tax-Free Investment Limits

What is an ISA Allowance?

An ISA (Individual Savings Account) allows UK residents to save or invest money without paying income or capital gains tax on the returns. Each tax year, you are provided with a tax-free allowance which you can spread across different types of ISAs: Cash ISA, Stocks & Shares ISA, Lifetime ISA, and Innovative Finance ISA.

Tracking your ISA usage helps ensure you're maximizing tax benefits without accidentally breaching the annual limit. Over-contributing may lead to penalties or reduced returns.
