Tax bands

To determine whether I'm entitled to 1,000 or 500 tax free savings interest income would I need to calculate my gross income from all sources prior to or after the application of personal allowances (e.g. 1,000 trading allowance / 1,000 property rental allowance / capital gains allowance etc)?

Hi HistoryBuff,
Eligibility for savings interest allowances are based on your Adjusted Net Income, which is your total taxable income before any Personal Allowances. As such, the personal allowances listed would not affect your eligibility for the savings interest allowances.
Personal Allowances: adjusted net income
Thank you.
