Understanding Tax on Savings Interest

Since April 2016, most UK savers have benefited from the Personal Savings Allowance (PSA), which allows a certain amount of savings interest to be earned tax-free each year. Basic rate taxpayers can earn up to \u00a31,000 in interest without paying tax, while higher rate taxpayers have a \u00a3500 allowance. Additional rate taxpayers do not receive any PSA.

When Savings Tax Becomes an Issue

With savings rates rising in recent years, more people are finding their interest exceeds the PSA. For example, \u00a325,000 in a savings account at 4.5% would earn \u00a31,125 in interest, exceeding the basic rate PSA by \u00a3125. Consider using ISAs to shelter savings from tax, as ISA interest does not count towards your PSA.
