UK Payroll Compliance: What Every Employer Needs to Know for 2026/27

Payroll compliance sits at the centre of every employer’s legal and financial responsibilities. It covers far more than paying people on time; it involves accurate deductions, correct statutory payments, timely reporting to HM Revenue and Customs (HMRC), and the secure handling of personal data. For many organisations, the difficulty is not understanding these obligations individually. It is keeping track of all of them at once, particularly as rules and rates change every tax year.

This guide sets out what payroll compliance means for UK employers in 2026/27, the areas that carry the greatest risk if overlooked, and the practical steps organisations can take to keep their processes reliable. Several rules changed from 6 April 2026, including adjustments to Statutory Sick Pay (SSP), National Insurance (NI), and the National Minimum Wage (NMW), which makes this a useful point to review your current approach.

 

What does payroll compliance actually involve?

At its core, payroll compliance means meeting a set of legal obligations each time you pay your employees. These include:

• Calculating gross and net pay correctly, including any variable elements such as overtime or commission
• Applying the correct tax codes, NI categories, and student loan deductions
• Making statutory payments (such as sick pay or maternity pay) where an employee qualifies
• Submitting accurate reports to HMRC through Real Time Information (RTI)
• Keeping employee records up to date and secure, in line with UK data protection law
• Issuing payslips, P45s, and other documents within the required timeframes

None of these obligations exist in isolation. A change to an employee’s circumstances, such as a new student loan plan or a change of tax code, can affect several parts of the payroll process at once. That is one reason payroll compliance is best treated as an ongoing discipline rather than a task completed at year end.

 

A breakdown of the main compliance areas

 

Employee records and right to work checks

Every organisation needs accurate, current records for each person on the payroll. This includes basic personal details, employment status, and payroll ID, but also extends to right to work verification. Irish citizens can confirm this using a passport; most other employees will need a government-issued share code, verified through gov.uk.

Employers must also identify which of the five student loan repayment plans applies to each employee, since each carries different thresholds and deduction rates. Getting a new starter’s details wrong at the outset tends to cause more administrative work later, so it is worth building a thorough onboarding checklist. For leavers, final pay must be confirmed and a P45 issued without unnecessary delay.

 

Pay rates and statutory payments

Several statutory rates change on 6 April each year, so this area needs particular attention:

• National Minimum Wage and National Living Wage: These are legal minimums, reviewed annually by the Low Pay Commission and confirmed by the Chancellor. Paying below the correct rate is one of the more visible compliance failures, and HMRC does publish the names of employers who get it wrong.
• Holiday pay: For employees on fixed hours, holiday pay is generally simple to calculate; they receive their normal pay while on leave. It becomes more involved for those on variable hours, shift patterns, or with regular commission and overtime, where holiday pay must reflect actual average earnings rather than a flat base rate. Workers in this category accrue holiday at 12.07% of hours worked, and employers may apply this on a rolled-up basis provided it is shown separately on the payslip. The statutory minimum across all workers is 5.6 weeks of paid leave per year.
• Statutory Sick Pay: From 6 April 2026, SSP became payable from the first day of sickness absence, removing the previous waiting period. The rate is the lower of £123.25 per week or 80% of average weekly earnings, for up to 28 weeks.
• Statutory Maternity, Paternity, Adoption, and Parental Payments: Statutory Maternity Pay (SMP) runs for up to 39 weeks: the first six at 90% of average weekly earnings, and the remaining 33 at the lower of £194.32 per week or 90% of average earnings. Statutory Paternity Pay (SPP), Statutory Adoption Pay (SAP), Shared Parental Pay (ShPP), and Statutory Parental Bereavement Pay (SPBP) follow similar structures, each with its own eligibility conditions and rates. Employers can usually reclaim 92% of these payments from HMRC, rising to 103% under Small Employers’ Relief.

 

Deductions: tax, National Insurance, pensions, and student loans

Each deduction type has its own set of rules, and all must be applied using the correct rates for the current tax year:

1. Income tax and NI must use the correct bands, categories, and thresholds.
2. Salary sacrifice arrangements need monitoring, so that no employee’s take-home pay falls below NMW.
3. Pension contributions must comply with both the employee’s agreement and auto-enrolment requirements.
4. Student loan deductions must match the correct plan type and threshold for each employee.

A well-configured payroll system will apply most of these automatically. If deductions are still being checked manually as a matter of routine, that is worth reviewing.

 

IR35 and contractor status

Where an organisation engages contractors operating through their own limited company, the off-payroll working rules (commonly known as IR35) may apply. For medium and large private sector employers, responsibility for assessing each contractor’s status sits with the organisation, not the contractor. A Status Determination Statement must be issued for each engagement, and where a contractor is assessed as inside IR35, tax and NI must be deducted before payment. HMRC’s Check Employment Status for Tax (CEST) tool is a reasonable starting point for straightforward cases, though more complex arrangements are usually worth checking with a specialist.

 

Payslips and leaver documents

Every employee is entitled to a payslip on or before payday, showing gross pay, net pay, and a breakdown of deductions. Hourly workers must also see their hours worked. When someone leaves, their P45 should be issued promptly, as their next employer will need it to set up payroll correctly.

 

Workplace pensions and auto-enrolment

Employees aged between 22 and State Pension age, earning above £10,000 a year, must be automatically enrolled into a qualifying pension scheme. The minimum total contribution is 8% of qualifying earnings (calculated on the band between £6,240 and £50,270), split between at least 3% from the employer and 5% from the employee. Proposals to lower the qualifying age to 18 and remove the lower earnings limit have been discussed but had not been implemented at the time of writing.

 

PAYE reporting: FPS, EPS, and gender pay gap data

Every payment run requires a Full Payment Submission (FPS) to HMRC, and where no one is paid in a given tax month, an Employer Payment Summary (EPS) should be sent instead. Our detailed guide to FPS and EPS submissions covers this process step by step, including how the EPS can be used to reclaim statutory payments or report the Apprenticeship Levy.

Organisations with 250 or more employees carry an additional obligation: annual gender pay gap reporting, covering mean and median pay gaps, bonus pay gaps, and the distribution of men and women across pay quarters.

 

How long records must be kept

HMRC can inspect payroll records at any point, and failing to produce them can result in a fine. The table below sets out the minimum retention periods for the main record types.

Data protection and GDPR

Payroll data is among the most sensitive personal information an organisation holds, and UK GDPR sets clear expectations for how it should be managed. Employees have the right to know what data is collected, why, how long it is kept, and who it may be shared with. They can also submit a Subject Access Request, ask for corrections, or in some cases request deletion.

On the employer side, obligations include processing data lawfully, collecting only what is genuinely required, applying appropriate security measures, and having a clear breach response plan that includes notifying both affected employees and the Information Commissioner’s Office (ICO) within the required timeframe. Penalties for non-compliance can reach £17 million or 4% of global annual turnover, whichever is higher, so this is not an area to leave unaddressed.

 

How different organisations approach payroll compliance in practice

The right approach often depends on the size and structure of the organisation.

A growing SME with 40 employees may handle payroll compliance in-house using a single payroll administrator supported by cloud-based software. This works well when the software is kept current and the administrator has time to track legislative updates, but it can come under strain during busy periods, such as the start of a new tax year, when several rate changes land at once.

A multi-site retail employer with a mix of salaried and shift-based staff faces more complexity around holiday pay and NMW calculations, given the volume of variable-hours workers. A lot of organisations in this position find that manual calculations create the greatest risk of error, particularly around rolled-up holiday pay.

A medium-sized professional services firm engaging contractors needs a consistent process for IR35 assessments and Status Determination Statements, since inconsistent handling across departments is a common source of non-compliance.

A larger organisation with 250 or more employees carries the added responsibility of gender pay gap reporting, alongside the core payroll obligations already outlined.

 

Best practice for staying compliant

A handful of practical habits make a meaningful difference to ongoing compliance:

• Review your payroll software provider’s update schedule each April, so new rates and thresholds are applied automatically rather than manually
• Build a clear onboarding checklist covering right to work checks, student loan declarations, and P45 or starter checklist collection
• Set calendar reminders for FPS and EPS deadlines, rather than relying on memory
• Keep a single, secure record of retention periods for each document type, so nothing is deleted early or kept longer than necessary
• Run a periodic audit of holiday pay calculations for variable-hours employees, since this is a recurring source of underpayment claims
• Document your IR35 assessment process so it is applied consistently across the organisation

This works well when payroll, HR, and finance teams share information routinely. Good news: most compliance failures stem from gaps between these teams or from outdated systems, rather than from a lack of knowledge, so addressing the underlying process tends to resolve several risks at once.

Building a payroll compliance routine that holds up under pressure

Payroll compliance is not a task to revisit once a year; it is a routine that needs to hold up through every pay run, every new starter, and every legislative change. The organisations that manage it well tend to share a common trait: their processes do not depend on one person remembering every rule. Instead, they rely on well-configured software, clear internal checklists, and regular communication between payroll, HR, and finance.

For 2026/27, with changes already in effect for SSP, NI, and NMW, and further changes to benefit-in-kind payrolling on the horizon, this is a sensible point to check that your current setup is keeping pace.
