What exactly is PAYE tax?
PAYE stands for “Pay As You Earn” and it’s the UK’s income tax collection system that’s been around since 1944. When you’re employed, your employer handles all the tax calculations for you.
They work out how much income tax and National Insurance you owe, deduct it from your gross pay, and send it directly to HMRC. PAYE ensures employees pay the correct amount of tax and National Insurance directly from their salaries. Both salaries and wages are subject to PAYE deductions, so the correct amounts are taken from employees' pay automatically. This automatic system means most employees don’t need to file a tax return.
Your tax obligations are handled with each payslip. PAYE covers both your income tax and National Insurance contributions from your employment income.
Understanding your tax code
Most tax codes consist of numbers and a letter, like 1257L. Your PAYE tax code determines how much tax is deducted from your income. The numbers represent your tax-free personal allowance divided by ten.
The letter provides additional information about your tax situation. For example, ‘L’ means you get the standard personal allowance, while ‘BR’ means all income from this job is taxed at the basic rate.
You can check your tax code on your payslip, P60, or through your personal tax account on the HMRC website. If your tax code is incorrect, you could end up paying too much or too little tax.
How PAYE tax is calculated and what rates apply
Understanding how your PAYE tax is calculated can help you make sense of your payslip and ensure you’re paying the correct amount of income tax and National Insurance contributions each month. When you receive your monthly salary, your employer uses your tax code, provided by HM Revenue and Customs (HMRC), to work out how much income tax to deduct from your gross pay. Your tax code reflects your personal allowance, which is the amount of income you can earn tax-free each tax year. For the 2024-2025 tax year, the standard personal allowance is £12,570.
Once your personal allowance is taken into account, the rest of your income is taxed according to the UK’s income tax bands. The basic rate of 20% applies to income between £12,571 and £50,270. If your earnings fall between £50,271 and £150,000, you’ll pay the higher rate of 40%. Any income above £150,000 is taxed at the additional rate of 45%. Your tax code ensures that the correct tax rate is applied to your earnings, so you pay income tax at the right level throughout the tax year.
National Insurance contributions are also deducted from your gross pay. For most employees, you’ll pay 12% on weekly earnings between £166 and £962, and 2% on anything above £962 per week. Your National Insurance category letter, shown on your payslip, determines the exact rate you pay. These contributions go towards your entitlement to benefits like the state pension and statutory pay.
Benefits of the PAYE system
PAYE makes tax payment simple and automatic for millions of UK workers. By spreading tax payments throughout the year, it helps with personal budgeting and cash flow.
For most employees with straightforward tax affairs, PAYE means you don't need to worry about filing tax returns. You also don't need to set aside money for large annual tax bills.
Your employer handles all the complex calculations and paperwork with HMRC. This saves you considerable time and hassle compared to self-assessment.
PAYE for employers
Employers have legal responsibilities to operate PAYE correctly for all staff. They must register with HMRC before employing people and maintain accurate payroll records. A business must be properly registered to meet payroll obligations and comply with HMRC regulations.
They must report payments and deductions in real-time through the RTI (Real Time Information) system. Employers must provide each employee with a payslip showing earnings and all deductions.
HMRC can impose penalties on employers who submit late or incorrect PAYE information. These penalties ensure employers take their PAYE responsibilities seriously. Completing all required payroll documentation and end-of-year returns accurately and on time is essential to avoid such penalties.
Final Thoughts
PAYE makes tax collection straightforward for millions of UK workers. It handles income tax and National Insurance contributions automatically through your employer.
It's worth checking your tax code regularly to make sure you're paying the right amount. This is especially important if your circumstances change during the tax year.
While PAYE works well for most people, those with multiple income sources might need additional arrangements. Complex tax situations often require more than just the basic PAYE system.
