What is a personal allowance in income tax?
Show answer
The amount you can earn in a year before paying any income tax (e.g. £12,570 in the UK).
How do you check whether a monthly wage exceeds a yearly tax threshold?
Show answer
Multiply the monthly wage by 12 and compare the annual total to the threshold.
Nora earns £1060 a month; the threshold is £12,570 a year. Does she pay tax?
Show answer
Yes — £1060 × 12 = £12,720, which is more than £12,570.
How do you find annual earnings from an hourly rate, weekly hours and weeks worked?
Show answer
Hourly rate × hours per week × weeks per year (e.g. £13.95 × 22 × 42 = £12,889.80).
Tax is 20% on all earnings over £10,000. What tax is due on £18,000?
Show answer
£1,600 — only the £8,000 above the threshold is taxed: 0.2 × 8,000.
With a rule like '19% on all earnings over $18,200', the tax is charged only on the amount ? the threshold, not the whole salary.
Show answer
above
Tax is 20% up to €36,800 then 40% on the rest. What tax is due on €40,000?
Show answer
€8,640 — 0.2 × 36,800 = €7,360 plus 0.4 × 3,200 = €1,280.
How do you calculate income tax with several tax bands?
Show answer
Split the salary into each band, work out the percentage for each band separately, then add the amounts together.
Bands: 0% on first £14,500, 10% on next £6,500, 20% on the rest. Tax on £52,000?
Show answer
£6,850 — £0 + £650 (10% of 6,500) + £6,200 (20% of the remaining £31,000).
Tax is 30% on earnings over £8,000. Jacob paid £1,800 tax. What did he earn?
Show answer
£14,000 — taxable amount = 1,800 ÷ 0.3 = £6,000, then add the £8,000 threshold.
How do you find a salary from the total tax paid under a two-band system?
Show answer
Subtract the tax from the full lower band, divide the remaining tax by the higher rate to get the amount in the top band, then add the lower band limit.
20% on the first €36,800, 40% on the rest; William pays €9,200 tax. What is his salary?
Show answer
€41,400 — €9,200 − €7,360 = €1,840; 1,840 ÷ 0.4 = €4,600; 36,800 + 4,600.
