Ever stared at your payslip feeling puzzled, or grappled with confusing tax terms while managing your UK business? You’re not alone. The distinction between payroll tax and income tax causes confusion for millions across the UK every year.
In fact, a recent HMRC survey reveals nearly 60% of British small business owners struggle to differentiate between these two taxes. This confusion can lead to costly compliance errors, unexpected fines, or missed savings opportunities.
Don’t worry! This blog clears up the confusion. We’ll break down what payroll and income taxes really mean, highlight their essential differences, provide actionable advice, and equip you with the knowledge to handle your taxes confidently.
Let’s get started.
What Exactly is Payroll Tax in the UK?
Payroll taxes in the UK refer mainly to National Insurance Contributions (NICs). They’re compulsory payments deducted directly from an employee’s salary and paid by employers too. This tax directly funds essential social services, including the NHS, state pensions, maternity benefits, and unemployment support.
In short: Payroll taxes fund your safety net.
Types of UK Payroll Taxes .
1. Employee National Insurance Contributions (NICs).
These deductions show up on your payslip every month, calculated based on your gross earnings. Rates differ based on salary thresholds:
Earnings per week (£) | Employee NICs Rate (2025) |
£242 – £967 | 12% |
Above £967 | 2% |
2. Employer National Insurance Contributions.
Employers must also contribute to NICs, calculated as a percentage of employee salaries.
Earnings per week (£) | Employer NICs Rate (2025) |
Above £175 | 13.8% |
Research by the Institute for Fiscal Studies (IFS) found payroll taxes (NICs) raised around £158 billion in 2024, funding nearly half of the UK’s welfare budget.
Understanding Income Tax in the UK: It’s More than Just a Deduction .
Income tax is levied on the money individuals earn from employment, self-employment, property, investments, and savings. Unlike payroll tax, income tax contributes directly to public services like education, roads, police, and national defence.
UK Income Tax Rates (2025)
Income tax rates vary based on annual earnings:

£50,271 to £150,000 | 40% (Higher Rate) |

Payroll Tax vs. Income Tax: 7 Crucial Differences .
Understanding these key differences clearly can help you handle tax obligations smoothly, avoiding costly errors:
Aspect | Payroll Tax (NICs) | Income Tax |
Purpose & Allocation | Funds welfare (e.g., NHS, pensions, benefits) | Funds public services, infrastructure, defence |
Taxpayer Responsibilities | Shared by employer and employee | Primarily individual; employers deduct only |
Calculation Method | Flat-rate percentage (weekly/monthly earnings) | Progressive rate (increases with earnings) |
Tax-Free Allowance | Lower threshold (£242 per week) | Higher personal allowance (£12,570 per year) |
Impact on Employers | Employers bear significant cost | Employers deduct but don’t personally pay |
Reporting & Filing | Monthly/Quarterly (via PAYE) | Annual self-assessment or PAYE deducted |
Consequences of Non-Compliance | Higher penalties, frequent audits | Penalties significant but negotiable with HMRC |
Top 3 Common Mistakes Businesses Make with Payroll & Income Tax .
Mistake #1: Mixing Payroll and Income Tax Payments
Avoid combining these tax payments, as they’re separate obligations with different deadlines.
Mistake #2: Forgetting Employer NICs

Misclassifying employees as freelancers (or vice versa) significantly affects tax obligations.
