Financial expert Martin Lewis suggests low-income individuals can save up to £18,570 tax-free by combining three savings exemptions.

Financial expert Martin Lewis discusses how individuals with low income and high-interest savings can potentially save up to £18,570 tax-free by combining three exemptions: the £12,570 tax-free personal allowance, the £5,000 starter rate of savings tax allowance, and applying personal allowance to savings income before the starter rate. This applies when earned income without counting savings falls below £17,570.
