[Exercise Query] Income Tax Liability

Hello,

Could you please help me with the following question?

Ann is self-employed. Her taxable income for the tax year 2022/23 was £76,000 which was all trading income. Ann made contributions of £49,000 (gross) into a personal pension scheme between September 2022 and March 2023. This was the seconf year that she had been a member of a pension scheme and she had an unused annual allowance of £20,000 brought forward from 2021/22.

What is Ann’s income tax liability for the tax year 2022/23>

Answer:
The available annual allowance is £40000 + £20000 + £60000 and so there is no annual allowance charge for the tax year 2022/23. The basic rate band limit is £37700 +£49000 so all of Ann’s taxable income is within the basic rate band. £76000 x 20% = £15200.

My reasoning:
If the pension allowance is £49,000 and the personal allowance is £12,570.
Should not the taxable income and tax liability be:
£76000 – £49000 – £12570 = £14430
£14430 x 20% =£2886?

Thanks in advance for you help.
