I have two sources of income. 1) Annual income £48,000 from my payroll job. 2) £1,010 from bank saving interest income. I test myself in https://www.gov.uk/check-if-you-need-tax-return and it said "Based on your answers, you do not need to send areturn for 2023 to 2024." In the test, it specific asked: 6. Did you get more than £10,000 from dividends or savings and investments? So I think I really do not need to submit self-assessment. However I read some where online saying I need to pay tax for interest income >£1,000. So how should I pay the tax without submit self-assessment?
