Payroll is the process by which employers calculate and pay their employees' wages, deduct Income Tax and National Insurance Contributions (NICs) under HMRC's Real Time Information (RTI) system, and maintain accurate employment records. In the UK, all employers must operate a compliant payroll, whether they employ one person or thousands. Payroll professionals manage everything from gross-to-net pay calculations and statutory payments to pension auto-enrolment and year-end reporting.
What is payroll and why does it matter for UK businesses?
Payroll is far more than simply paying people on time. In the UK, it is a legally regulated function that sits at the intersection of employment law, tax legislation, and financial reporting. Every time an employee is paid, the employer must:
- Calculate gross pay (including salary, overtime, bonuses, and commission)
- Deduct Income Tax via the PAYE (Pay As You Earn) system
- Calculate and deduct employee National Insurance Contributions (NICs)
- Calculate the employer's NIC liability
- Process any statutory payments - Statutory Sick Pay (SSP), Statutory Maternity Pay (SMP), Statutory Paternity Pay (SPP), and Statutory Shared Parental Pay (ShPP)
- Apply student loan deductions where applicable
- Administer workplace pension contributions under auto-enrolment rules
- Submit a Full Payment Submission (FPS) to HMRC on or before each payday
- Produce payslips for every employee (a legal requirement under the Employment Rights Act 1996)
Getting payroll wrong carries real consequences - HMRC penalties, employee disputes, and reputational damage. That is why skilled payroll professionals are in consistent demand across every sector of the UK economy.
How does UK payroll work step by step?
Understanding the payroll cycle helps you appreciate why specialist knowledge matters. A typical UK monthly payroll follows these stages:
1. Collect and verify employee data
Before any calculation begins, payroll teams confirm hours worked, any changes to contracts, new starters (using a P45 or starter checklist), and leavers.
2. Calculate gross pay
Gross pay is the total amount earned before any deductions. For salaried employees this is straightforward; for hourly workers it requires multiplying hours by the applicable rate, including the National Living Wage (NLW) or National Minimum Wage (NMW) floors set by the government each April.
3. Apply tax codes and calculate Income Tax
HMRC issues each employee a tax code (e.g. 1257L for the standard 2025/26 personal allowance of £12,570). Payroll software uses this code to calculate the correct PAYE deduction using the relevant tax tables or the cumulative method.
4. Calculate National Insurance Contributions
Both employees and employers pay NICs above the relevant earnings thresholds. For 2025/26, employees pay Class 1 NICs at 8% on earnings between the Primary Threshold (£12,570 per year) and the Upper Earnings Limit (£50,270 per year), and 2% above that. Employers pay Class 1 NICs at 15% above the Secondary Threshold (£5,000 per year).
5. Process deductions and additions
This includes pension contributions, student loan repayments, attachment of earnings orders, and any salary sacrifice arrangements.
6. Calculate net pay
Net pay = Gross pay minus Income Tax minus Employee NICs minus Other deductions, plus any additions (e.g. expenses reimbursements).
7. Submit RTI data to HMRC
Under Real Time Information (RTI), employers must send a Full Payment Submission (FPS) to HMRC on or before each payday. If no employees are paid in a period, an Employer Payment Summary (EPS) may be required instead.
8. Pay employees and HMRC
Employees receive net pay; HMRC receives the combined PAYE and NIC liability, typically by the 19th (cheque) or 22nd (electronic) of the following month.
9. Issue payslips
Every employee must receive an itemised payslip on or before payday.
10. Year-end tasks
At the end of the tax year (5 April), payroll teams submit a Final Payment Submission, issue P60s to all employees still in employment, and issue P45s to leavers throughout the year.

What qualifications do you need to work in payroll in the UK?
There is no single mandatory qualification for payroll work in the UK, but employers consistently favour candidates with recognised credentials that demonstrate technical competence. The most respected pathway for aspiring payroll and accounting professionals is the AAT (Association of Accounting Technicians) qualification suite.
AAT qualifications and payroll: what's covered at each level?
AAT qualifications are structured across three levels, each building on the last. Payroll-relevant content appears from Level 2 upwards, with dedicated payroll units at Level 3.
| AAT Level & Title | Payroll-Relevant Units | Typical Duration | Entry Requirements | What's Next |
|---|---|---|---|---|
| Level 2 - AAT Foundation Certificate in Accounting | Introduction to Bookkeeping; Principles of Bookkeeping Controls (payroll journals, basic employment costs) | 6-12 months | No formal entry requirements; suited to school leavers and career changers | AAT Level 3 |
| Level 3 - AAT Advanced Diploma in Accounting | Business Tax (employment income, benefits); Advanced Bookkeeping (payroll control accounts); Final Accounts Preparation | 12-18 months | AAT Level 2 or relevant experience | AAT Level 4 |
| Level 4 - AAT Professional Diploma in Accounting | Personal Tax (PAYE, employment income, P11Ds); Business Tax (employer NICs, employment costs); optional specialist units | 18-24 months | AAT Level 3 or equivalent | ACCA, CIMA, ICAEW chartered routes; senior payroll/finance roles |
Note: AAT Level 3 and Level 4 both include tax units that cover payroll-related legislation in depth, making them highly relevant for anyone pursuing a payroll career. Learndirect is an AAT Approved Training Provider, delivering AAT qualifications online with tutor support.
What does a payroll professional actually do day to day?
Job titles in payroll range from Payroll Administrator and Payroll Officer to Payroll Manager and Head of Payroll. Responsibilities scale with seniority, but core daily tasks typically include:
- Processing new starters and leavers
- Updating employee records (pay changes, tax code changes, address updates)
- Running payroll calculations for the relevant pay period
- Checking payroll reports for errors before submission
- Responding to employee queries about their payslips
- Liaising with HR and finance teams
- Ensuring compliance with the latest HMRC guidance and employment legislation
- Managing pension contributions and liaising with pension providers
Senior payroll professionals also oversee system implementations, manage payroll teams, and advise on complex issues such as off-payroll working rules (IR35), expatriate payroll, and TUPE transfers.
What payroll software is used in the UK?
Most UK employers use dedicated payroll software to automate calculations, generate RTI submissions, and produce payslips. The most widely used platforms include:
| Software | Who uses it | Key features |
|---|---|---|
| Sage 50 Payroll | SMEs and mid-market businesses | RTI submissions, auto-enrolment, P60/P45 production, pension integration |
| Sage Business Cloud Payroll | Small businesses and sole traders | Cloud-based, HMRC-recognised, accessible anywhere |
| Xero Payroll | Small businesses already using Xero accounting | Integrated with Xero ledger, RTI-compliant |
| BrightPay | Accountants and bureaux | Bureau-friendly, auto-enrolment tools, employee self-service |
| HMRC Basic PAYE Tools | Micro-employers (fewer than 10 employees) | Free, HMRC-provided, RTI-compliant |
| MoneySoft Payroll Manager | Accountants and payroll bureaux | Multi-company, RTI, pension integration |
Sage is among the most widely recognised payroll platforms in the UK. Learndirect is a Sage training partner, offering courses that develop practical skills in Sage software, helping you become job-ready faster.
What is the difference between payroll and bookkeeping?
Payroll and bookkeeping are closely related but distinct functions:
Bookkeeping records all financial transactions of a business - sales, purchases, receipts, and payments - in the accounting system. It produces the trial balance, management accounts, and supports year-end financial statements.
Payroll is a subset of financial administration focused specifically on employee remuneration. However, payroll data feeds directly into the bookkeeping system: net wages are a business expense, employer NICs are a liability, and pension contributions appear on the balance sheet.
In small businesses, one person often handles both functions. In larger organisations, payroll sits within HR, finance, or a dedicated payroll bureau. Understanding both disciplines, as AAT qualifications teach, makes you significantly more employable.
What are typical payroll salaries in the UK?
Payroll salaries vary by region, sector, and level of responsibility. The figures below are indicative based on publicly available data from sources including the Office for National Statistics and major job boards.
| Role | Typical UK Salary Range |
|---|---|
| Payroll Administrator (entry level) | £22,000 to £28,000 |
| Payroll Officer | £26,000 to £34,000 |
| Payroll Supervisor | £32,000 to £40,000 |
| Payroll Manager | £40,000 to £55,000 |
| Head of Payroll / Payroll Director | £55,000 to £80,000+ |
London and the South East typically attract a 10-20% premium above these figures.
How do you get started in a payroll career?
A payroll career is accessible to school leavers, graduates, and career-changers alike. Here is a practical roadmap:
- Build your foundations - Start with AAT Level 2 (Foundation Certificate in Accounting) to understand bookkeeping, financial documents, and basic employment costs. No prior experience is required.
- Develop payroll-specific knowledge - Progress to AAT Level 3 (Advanced Diploma in Accounting), where you study business tax, payroll control accounts, and employment income in depth.
- Master payroll software - Gain hands-on skills in Sage Payroll or another leading platform. Employers value practical software competence as much as theoretical knowledge.
- Gain work experience - Look for payroll administrator roles, apprenticeships, or work placements. Many learndirect students study while working, applying their learning in real time.
- Progress to senior roles - With AAT Level 4 and several years' experience, you can move into payroll management, consultancy, or use your AAT qualification as a stepping stone to chartered accountancy routes such as ACCA, CIMA, or ICAEW.
Frequently asked questions
What is payroll in simple terms?
Payroll is the process of calculating and paying employees their wages, deducting the correct amounts of Income Tax and National Insurance, and reporting this information to HMRC. Every UK employer with at least one employee must operate a payroll.
Is payroll part of accounting?
Yes. Payroll is a core component of financial administration. Payroll costs, including wages, employer NICs, and pension contributions, are recorded in the business's accounts, and payroll professionals work closely with finance and HR teams. AAT qualifications cover payroll within their accounting and tax units.
Do I need a qualification to work in payroll?
There is no single mandatory qualification, but most employers prefer candidates with a recognised credential. The AAT qualification is widely respected by UK employers and covers the payroll-related knowledge you need, including PAYE, NICs, statutory payments, and employment tax.
Which AAT level covers payroll?
Payroll content appears across the AAT qualification suite. AAT Level 2 introduces employment costs and payroll journals. AAT Level 3 covers business tax and payroll control accounts in more depth. AAT Level 4 includes personal tax and business tax units that address PAYE, employment income, and employer NICs in detail.
What is PAYE?
PAYE stands for Pay As You Earn. It is HMRC's system for collecting Income Tax and National Insurance Contributions directly from employees' wages before they are paid. Employers are responsible for operating PAYE correctly and submitting data to HMRC via Real Time Information (RTI).
What is RTI in payroll?
RTI stands for Real Time Information. Introduced by HMRC in 2013, RTI requires employers to submit payroll data to HMRC on or before each payday, rather than annually. This is done via a Full Payment Submission (FPS) using HMRC-recognised payroll software.
What is auto-enrolment?
Auto-enrolment is the legal requirement for UK employers to automatically enrol eligible workers into a qualifying workplace pension scheme and make minimum employer contributions. Payroll teams play a central role in administering auto-enrolment, calculating contributions, and liaising with pension providers.
What payroll software should I learn?
Sage Payroll (including Sage 50 Payroll and Sage Business Cloud Payroll) is among the most widely used payroll platforms in the UK and is highly valued by employers. Learndirect, as a Sage training partner, offers courses to help you develop practical Sage skills.
Can I study payroll qualifications online?
Yes. Learndirect delivers AAT qualifications and Sage software training entirely online, with tutor support, so you can study at your own pace around existing work or family commitments. Visit the relevant course page for current delivery details.
How long does it take to qualify in payroll?
If you start from scratch with AAT Level 2, you can complete Levels 2 and 3 in approximately 18-30 months of part-time study. Many students enter the workforce at Level 2 or 3 and continue studying while working. Adding Sage software training can be achieved in a matter of weeks alongside your AAT studies.
What is the difference between a P45 and a P60?
A P45 is issued by an employer when an employee leaves their job. It shows the employee's total pay and tax deductions up to their leaving date and is used by their new employer to set up their payroll correctly. A P60 is issued annually (by 31 May) to every employee still in employment at 5 April (the end of the tax year). It summarises total pay and deductions for the full tax year.
Is payroll a good career in the UK?
Yes. Payroll is a stable, in-demand profession. Every UK employer must operate a payroll, creating consistent demand for skilled professionals across all sectors. With experience and qualifications, payroll professionals can progress to management roles, consultancy, or broader finance careers.
