Navigating the UK tax system can seem overwhelming, but understanding the basics can help you manage your finances better.

This guide will focus on Income Tax and National Insurance, explaining how they work and how much you might need to pay based on your earnings.

Types of Taxes in the UK

The UK has several types of taxes, including:

• Income Tax – Charged on earnings above a set threshold.

• National Insurance (NI) – A separate deduction from salaries for state benefits.

• Dividend Tax – Applied to income from shares.

• Capital Gains Tax – Paid on profits from selling assets.

• Value Added Tax (VAT) – A tax on goods and services.

• Council Tax – A local government tax for services such as waste collection.

In this guide, we’ll focus on Income Tax and National Insurance.

Income Tax: How Much Will You Pay?

Income Tax is applied to earnings above the personal allowance, which is the amount you can earn before paying tax.

Personal Allowance for 2023/2024

The personal allowance is £12,570 per year. If you earn below this amount, you do not pay Income Tax.

Income Tax Rates for 2023/2024

Income Range (£) Tax Rate (%)

• £0 - £12,570 0% (Tax-free personal allowance)

• £12,571 - £50,270 20% (Basic Rate)

• £50,271 - £125,140 40% (Higher Rate)

• Over £125,140 45% (Additional Rate)

Example: Income Tax Calculation

Let’s say you earn £30,000 per year.
1. The first £12,570 is tax-free.
2. The remaining £30,000 - £12,570 = £17,430 falls under the basic rate (20%).
3. 20% of £17,430 = £3,486 (this is your annual Income Tax).
4. Monthly Income Tax = £290.50.

National Insurance (NI): What You Need to Know

National Insurance is another tax deducted from your salary. It helps fund state benefits such as pensions and healthcare.

National Insurance Rates (2023/2024)

Weekly Earnings (£) NI Rate (%)

• Below £242 0% (No NI contributions)

• £242 - £967 10%

• Over £967 2%

Example: National Insurance Calculation

Let’s assume you earn £5,000 per month.
1. The first £1,048 is NI-free.
2. The next £4,189 is taxed at 10%, which equals £418.90.
3. The remaining £811 is taxed at 2%, which equals £16.22.
4. Total NI Contribution = £435.12 per month.

What’s Your Take-Home Pay?

Let’s revisit the example of someone earning £30,000 per year:

• Income Tax: £3,486 per year

• National Insurance: £1,743 per year

• Total Deductions: £5,229 per year

Final Take-Home Pay
• Annual Take-Home Pay = £30,000 - £5,229 = £24,771
• Monthly Take-Home Pay = £2,064.25
• Weekly Take-Home Pay = £516
• Daily Take-Home Pay = £73.71

Key Takeaways

• The first £12,570 of your income is tax-free.

• If you earn between £12,571 and £50,270, you pay 20% tax on the portion above £12,570.

• National Insurance is charged separately from Income Tax and applies to earnings above £242 per week.

• Tax rates change almost every year based on the Finance Act passed by Parliament.

Understanding taxes helps you plan your finances, budget effectively, and ensure you’re paying the right amount.
