Understanding UK PAYE income tax rates in 2025 is necessary, especially if one is an employee or planning their finances. Each month, an amount of taxes is deducted from an employee's salary before it reaches their bank account, but many employees do not know how PAYE works, how much they are actually paying, or how to calculate their real take-home pay.
This resource outlines the UK PAYE income tax rates for 2025/26, explains how salary tax is computed, and demonstrates how a UK salary tax calculator helps to accurately estimate your net income.
What is PAYE in the UK?
PAYE (Pay As You Earn) – This is a way of paying income tax and national insurance contributions directly from your salary. Your employer calculates your tax based on your tax code, income tax, and national insurance contributions, then deducts it directly from each of your pay periods.
PAYE applies to:
- Full-time employees
- Part-time employees
- Pension income
- Some benefits in kind
Using this system, you spread your tax payments throughout the year so that you are not required to pay a huge amount of tax at a time.
UK Income Tax Rates 2025/26 (England, Wales & Northern Ireland)
For the tax year 2025/26, the income tax system for the majority of the UK operates on a progressive band system. This means you will pay different rates of tax on different parts of your income.
| Income Band | Taxable Income | Tax Rate |
|---|---|---|
| Personal Allowance | Up to £12,570 | 0% |
| Basic Rate | £12,571 – £50,270 | 20% |
| Higher Rate | £50,271 – £125,140 | 40% |
| Additional Rate | Over £125,140 | 45% |
Important: You will only be charged for higher earnings in the bracketed amount and not for your total earnings.
Personal Allowance Explained (2025)
Personal allowance is how much you can earn tax-free. For the majority of UK taxpayers, this is set to remain at £12,570 for 2025.
However:
- If you earn more than £100,000, your tax allowance reduces.
- For every £2 earned above £100,000, you lose £1 allowance.
- At £125,140, your personal allowance becomes £0.
This will result in a higher effective tax rate for certain high-income earners.
Scotland PAYE Income Tax Rates (Different System)
If you are a resident in Scotland, the income tax bands are slightly more complicated. The Scottish PAYE rates and bands are complex, with several bands, including:
- Starter rate
- Basic rate
- Intermediate rate
- Higher rate
- Advanced and top rates
These apply only to earned income, not to savings or dividends. If you find yourself in the UK, especially in Scotland, it is highly essential to have a UK salary tax calculator with Scotland support.
How PAYE Salary Tax Is Calculated
Your PAYE tax is calculated this way:
1. Gross Salary
Your total earnings before deductions.
2. Apply Personal Allowance
The tax-free component is eliminated.
3. Apply Income Tax Bands
Every slice of income gets charged at an applicable rate.
4. Divide Annually Calculated Tax
The total tax is distributed on a monthly or weekly paycheck.
5. Deduct Automatically
TAX is included in your payment slip.
This whole procedure is done electronically through their payroll.
National Insurance Contributions (NICs)
Apart from income tax, UK workers also have to pay National Insurance Contributions. These go towards funding benefits, pensions, and health care.
For most employees:
- No NICs below the threshold
- Standard Rate on earnings up to the Upper Limit
- Lower rate on earnings above that
NICs have a major effect on how much your net salary is. That is why you find them on the salary tax calculator.
