Answer:
£3600.
Explanation:
The taxable income would be the amount earned minus the tax-free personal allowance. So, for someone earning £30000 and with a personal allowance of £12000, their taxable income would be:
£30000 - £12000 = £18000
The basic rate of Income Tax is 20%, so the amount of tax owed on the taxable income would be:
20% x £18000 = £3600
Therefore, the Income Tax paid by someone earning £30000 with a personal allowance of £12000 would be £3600.
