How your tax is calculated
Every person in the UK has a personal tax allowance of £11,850 this financial year (2018-2019), which means that for the first £11,850 that you are earning, you’ll pay no tax. That income can be from one or multiple jobs – just don’t forget to add all the income sources together. There are different tax bands, from 0 to £11,850 you’ll pay no tax, from £11,850 to £46,350 you’ll pay 20% tax, and from £46,350 to £150,000 you’ll pay 40% tax.
For example if you are earning £50,000 a year. Out of this sum, you’ll pay the basic rate of 20% tax on £34,500 (£50,000 minus your personal allowance of £11,850, up to the higher earnings limit of £46,350): £6,900 basic rate tax will be deducted. Because you are earning above the higher rate tax limit of £46,350, you’ll also pay higher rate tax on £3,650 (£50,000 minus the higher rate limit of £46,350) at 40% – £1,460 higher rate tax will be deducted.
A simplified illustration of your tax:
- You’ll pay no tax on the first £11,850 that you’re earning.
- Total tax paid: £8,360
How is your National Insurance calculated
You won’t pay any National Insurance if you earn below £8,424 a year. For any earnings above £8,424 you’ll have to pay National Insurance, at the rate of 12%. Also, if you earn above £46,350, your National Insurance will drop to 2%, but only for the sum above that limit. For the sum below this limit of £46,350, you’ll still pay the normal rate of 12%.
For example, from your total salary of £50,000 you are earning a total sum of £37,926 above the National Insurance threshold that qualifies for the 12% rate National Insurance, which means you will pay £4,551normal rate National insurance. Also, because you are earning above the higher rate NI threshold of £46,350 a total sum of £3,650 will qualify for 2% National Insurance.
A simplified breakdown of your National Insurance:
- You’ll pay no NI on the first £8,424 that you’re earning.
- Total NI paid: £4,624
