Income tax computation

Based on the information provided in the knowledge base, we can calculate the tax charged for a person with a non-savings income of £145,000 and savings income of £7,850. For the non-savings income of £145,000, the tax calculation would be as follows: - £37,700 taxed at 20% = £7,540 - Remaining £107,300 (£145,000 - £37,700) taxed at 40% = £42,920 For the savings income of £7,850, the tax calculation would be as follows: - £500 taxed at 0% = £0 - Remaining £7,350 (£7,850 - £500) taxed at 40% = £2,940 Adding up the tax amounts for non-savings and savings income: £7,540 + £42,920 + £0 + £2,940 = £53,400 Therefore, the amount of tax charged for a person with a non-savings income of £145,000 and savings income of £7,850 would be £53,400. Kindly assist with the above computation from Tax AI. According to my knowledge this is incorrect as the additional rate payers don't qualify for the savings nil rate band.
