Your Ultimate Guide to Income Tax Rates and Personal Allowances

income tax rates and personal allowances

Understanding income tax rates and personal allowances can seem tricky at first. 

But if you think about it, it’s not that complicated: the UK operates a progressive tax system, meaning the more you earn, the higher the rate at which you’re taxed. 

Read on to learn all about personal tax allowance, income tax bands, National Insurance contributions and more. 

Some key definitions 

Here are some key definitions around income tax rates and personal allowances.

Income tax

Income tax is a tax imposed by the government on an individual’s or entity’s earnings.  

These earnings can come from various sources, including wages, salary, pensions, rental income, savings, and investments. The amount of tax an individual or business pays depends on the level of income, with different tax bands and rates applied to different portions of income.  

Income tax is collected by HM Revenue & Customs (HMRC) through mechanisms such as PAYE (Pay As You Earn) for employees and self-assessment for self-employed individuals.  

The rates and thresholds can change each tax year, and there are certain allowances and reliefs that may reduce the amount of tax payable. 

Personal allowance

Personal allowance is the amount of income an individual in the UK can earn tax-free each tax year. 

For the 2024/25 tax year, the standard personal allowance is £12,570. It’s gradually reduced for individuals with an adjusted net income over £100,000, decreasing by £1 for every £2 earned above this threshold.  
 
Those earning over £125,140 receive no personal allowance. 

HMRC

HMRC is the government department in the UK responsible for collecting taxes, paying benefits, and making sure people and businesses follow tax laws.  

They handle things like income tax, VAT, as well as provide support for people who need financial help, like through the Universal Credit system. 

Income Tax

In the 2024/25 tax year, you can earn up to £12,570 before you have to pay tax—this is called your personal allowance.  

However, this isn’t guaranteed. If your income goes over £100,000, your allowance decreases by £1 for every £2 you earn above that amount, until it eventually disappears. 

There are a few different income tax rates in the UK. you need to know about. Let’s break them down.

What about tax codes?

Let’s take a look at the UK tax codes and what they mean:

National Insurance contributions

It isn’t just the ins and outs of tax you need to be aware of, there’s also National Insurance contributions (NICs).  

If you’re interested in a comprehensive overview of NICs, you can read all about them in our National Insurance rates and categories guide.  

However, if you’re looking for a quick summary, look no further: 

  • Class 1: This is paid by employees earning over £242 a week and are under the State Pension age. 
  • Class 1A or 1B:Class 1A NICs and Class 1B NICs are paid on employees’ expenses or benefits. 
  • Class 2:Since 6 April 2024, self-employed people with profits under £6,725 are no longer required to pay Class 2 NICs. They can, however, choose to make voluntary contributions if they wish. 
  • Class 3: This is a voluntary top-up employees can make to fill gaps in their National Insurance record. 
  • Class 4: Paid by self-employed people earning more than £12,570 a year in profit. For profits between £12,570 and £50,270, a 6% contribution is applied, at over £50,270, 2% is applied. 

Personal allowances 

Before we look at each allowance individually, here’s an overview of the allowance rates for 2024/25:  

Allowance type 

Rate 

Personal allowance 

£12,570 

Married couple’s allowance 

£11,080 

Blind person’s allowance 

£3,070 

Marriage allowance 

£1,260 

Trading allowance 

£1,000 

Property allowance 

£1,000 

Personal allowance

Personal allowance (as explained in the definitions section above) is the amount of income you can earn each year without having to pay tax on it.  

For most people, the standard personal allowance is £12,570, which means you don’t pay tax on earnings up to that amount.  

Married couple’s allowance

The married couple’s allowance (MCA) is a tax benefit that reduces your tax bill rather than directly lowering your taxable income.  

If you’re married or in a civil partnership and at least one of you was born before 6 April 1935, you might be eligible for this allowance.  

For the 2024/25 tax year, the full MCA is £11,080, which can give you a maximum tax deduction of £1,108. However, if your income exceeds £37,000, you might not receive the full MCA.  

It’s also important to note that you can only claim one MCA per couple, and no part of the allowance can be refunded if you don’t owe any tax. 

Blind person’s allowance

The blind person’s allowance (BPA) is a tax-free allowance that reduces your taxable income.  

It’s an extra allowance on top of the standard personal allowance, but you won’t get it automatically—you have to claim it.  

For the 2024/25 tax year, the BPA is £3,070. You don’t need to be completely blind to qualify, but you must meet certain conditions:

  • If you live in England or Wales, you need to be registered as severely sight impaired.  
  • If you live in Scotland or Northern Ireland, your sight must be so poor that it prevents you from working. 


Your income level doesn’t affect your entitlement, and there’s no age restriction—if you qualify, you get the full amount. 

Marriage allowance

Marriage allowance is a tax benefit that allows you to transfer £1,260 of your personal allowance to your husband, wife, or civil partner, potentially reducing their tax bill by up to £252 in the tax year. 

You may be eligible for marriage allowance if you meet all of these conditions: 

  • You’re married or in a civil partnership. 
  • You either don’t pay income tax or your income is below the personal allowance threshold. 
  • Your partner pays income tax at the basic rate (see above). 

Trading allowance

The trading allowance is a tax exemption that lets individuals earn up to £1,000 a year, without needing to report it to HMRC. 

This applies to income from: 

  • Self-employment. 
  • Casual services (such as babysitting or gardening).
  • Renting out personal equipment (like power tools).


If your total income from these activities exceeds £1,000, or if you have other income over £2,500, you must register for Self Assessment and declare it to HMRC. 

Property allowance

The property allowance lets you earn up to £1,000 a year from rental income tax-free. If your total rental earnings stay under this limit, you don’t need to tell HMRC or register as a landlord.  

However, if your rental income exceeds £1,000, you’ll need to declare it, and if it’s more than £2,500, you must register for Self Assessment. 

Can your personal allowance change?

Yes. Your personal allowance isn’t always a fixed amount—it can change depending on your circumstances.  

Here are some of the factors that may affect your personal allowance: 

Taxable benefits

If your job comes with perks like a company car, private healthcare, or travel expenses, these are known as benefits in kind (BIK). They’re considered part of your taxable income, which means they can push up your total earnings. When that happens, your personal allowance might be reduced, meaning you start paying tax on more of your income.

Salary sacrifice schemes

A salary sacrifice scheme is where you agree to take a lower salary in exchange for non-cash perks—like extra pension contributions or childcare vouchers.  

Since your salary is technically lower, this could reduce your taxable income, meaning you might keep more of your personal allowance and pay less tax overall. 

Income thresholds

If your total income exceeds £100,000, your personal allowance decreases by £1 for every £2 earned above this threshold.  

This means you could see your personal allowance reduced or eliminated entirely. 

Value Added Tax

VAT (or Value Added Tax) is a tax added to the price of most goods and services in the UK. 

If you’re a business owner, you’ll need to register for VAT if your taxable turnover exceeds £90,000 in a 12-month period.  

Once registered, you’ll charge VAT on your sales and reclaim the VAT you’ve paid on your purchases.   

Here are the VAT rates for 2024/25: 

 

% of VAT  

What the rate applies to  

Standard rate  

20 

Most goods and services  

Reduced rate  

5 

Some goods and services, e.g. children’s car seats and home energy  

Zero rate  

0 

Zero-rated goods and services, e.g. most food and children’s clothes  

 

Tax credits

A tax credit is a form of government financial support aimed at helping individuals and families on low incomes.  

There are two main types of tax credits: 

  1. Child tax credit: available to individuals with children, regardless of whether they’re in work. The amount of credit depends on factors such as the number of children and the household income. 
  2. Working tax credit: available to people in work who have a low income, regardless of whether they have children.
