Running payroll in the United Kingdom became more demanding in 2025. International employers had to absorb higher employment-related charges, updated wage rates, new statutory leave rules, and revised payroll thresholds, often while managing teams from outside the country.
The difficulty is not simply knowing that a rule changed. Employers must also update payroll calculations, employment budgets, HR policies, reporting processes, and internal systems at the right time.
For companies hiring their first employee in the UK or expanding an existing British team, missing one update can create inaccurate pay, delayed reporting, employee complaints, or compliance exposure.
Here is what changed during 2025 and what international employers should review.
The UK Payroll Year Does Not Follow the Calendar Year
One of the first details international employers need to understand is that the UK tax year does not begin in January.
The 2025–2026 tax year ran from April 6, 2025, to April 5, 2026. However, some employment changes, including minimum wage updates, began on April 1 rather than April 6.
That difference matters.
Payroll teams must track:
- Calendar-year reporting requirements
- UK tax-year thresholds
- April 1 wage changes
- April 6 tax and National Insurance changes
- Employee-specific circumstances
- The payroll period in which each change applies
Using January as the automatic start of every payroll cycle can result in outdated rates being applied for several months.
Employer National Insurance Became More Expensive
The most significant UK payroll change for many employers in 2025 involved employer National Insurance contributions.
From April 6, 2025:
- The main employer National Insurance rate increased from 13.8% to 15%
- The annual secondary threshold fell from £9,100 to £5,000
- Employers generally began paying contributions sooner on each employee’s earnings
The lower threshold means that even employers with lower-paid or part-time workers may have seen a larger payroll liability. The change applies not only to the contribution percentage but also to the amount of earnings exposed to employer National Insurance.
For international businesses, this created a common budgeting problem: an employee’s gross salary may have stayed the same while the total employment burden increased.
What employers should check
Review whether your organization has:
- Updated the employer National Insurance rate in its payroll system
- Applied the correct secondary threshold
- Revised employment forecasts for UK-based workers
- Recalculated the total burden for new hires
- Confirmed that payroll reports are using the correct tax-year settings
A salary budget that ignores employer contributions does not provide a complete view of UK hiring obligations.
Employment Allowance Rules Also Changed
While employer National Insurance increased, the UK government also expanded Employment Allowance.
From April 2025, the maximum allowance rose from £5,000 to £10,500, and the previous £100,000 employer National Insurance eligibility limit was removed. This made the allowance available to a broader group of eligible employers.
However, international employers should not assume automatically that they qualify.
Eligibility can depend on the employer’s structure, activities, connected companies, and UK payroll arrangement. The allowance also needs to be claimed correctly through payroll reporting.
The practical lesson is simple: do not ignore the allowance, but do not apply it without confirming eligibility.
Minimum Wage Rates Increased
New National Minimum Wage and National Living Wage rates took effect on April 1, 2025.
| Worker category | Rate from April 1, 2025 |
| Age 21 and over | £12.21 per hour |
| Age 18 to 20 | £10.00 per hour |
| Age 16 to 17 | £7.55 per hour |
| Eligible apprentices | £7.55 per hour |
The accommodation offset also increased to £10.66 per day.
These changes were especially important for employers in hospitality, retail, support services, logistics, and other sectors with hourly or shift-based workforces.
Checking the employee’s headline hourly rate is not always enough. Employers may also need to review deductions, unpaid working time, training periods, uniforms, salary-sacrifice arrangements, and how working hours are recorded.
An employee who appears to earn above the minimum may still fall below the legal rate after certain deductions or unpaid work activities are considered.
New Neonatal Care Leave and Pay Entered Payroll
A major family-related change arrived on April 6, 2025.
Eligible employees whose baby was born on or after that date may qualify for Neonatal Care Leave and, where the payment conditions are met, Statutory Neonatal Care Pay.
Employees can receive up to 12 weeks of leave where a baby receives qualifying neonatal care. The entitlement is separate from other family leave and must be handled under its own eligibility and recordkeeping rules.
This means payroll and HR teams need a process for:
- Recording the baby’s birth date
- Confirming the neonatal care period
- Checking employee eligibility
- Calculating the statutory payment
- Recording leave separately from maternity, paternity, adoption, or shared parental leave
- Retaining supporting information
Employers relying on outdated leave categories may incorrectly place neonatal leave under another absence type.
Statutory Payment Rates Were Updated
Statutory maternity, paternity, adoption, shared parental, parental bereavement, sick, and neonatal payments are tied to government rules and may change between tax years.
For the 2025–2026 year, payroll systems needed updated statutory rates and earnings thresholds. For example, Statutory Sick Pay increased to £118.75 per week for the applicable 2025–2026 period, while the standard rate used for several family-related statutory payments increased to £187.18, subject to the relevant earnings-based calculation.
International employers should avoid copying the previous year’s statutory payment figures into a new payroll calendar.
Every statutory payment should be checked against:
- The employee’s average weekly earnings
- The qualifying period
- Length-of-service rules
- Required notices and evidence
- The statutory rate in effect
- Recovery rules available to the employer
Payroll Reporting Still Depends on Accurate Real-Time Information
UK employers generally report payroll information to HM Revenue & Customs through Real Time Information.
The Full Payment Submission normally includes employee pay, deductions, tax, National Insurance, and other relevant information. It must usually be filed on or before the employee’s payday.
The 2025 changes made accurate configuration especially important. A payroll system may calculate salary correctly but still report the wrong National Insurance threshold, statutory payment, or employee category.
Common reporting risks include:
- Using an incorrect tax code
- Submitting after payday
- Duplicating an employee record
- Applying the wrong National Insurance category
- Failing to report a starter or leaver correctly
- Recording an irregular payment in the wrong period
- Misclassifying a taxable benefit or reimbursement
The HMRC employer guide for 2025–2026 provides the operational framework employers need when running PAYE and National Insurance.
International Employers Need More Than Payroll Software
Software can automate calculations, but it cannot correct weak employment data or unclear responsibilities.
Before processing UK payroll, international organizations should know:
- Who is legally employing the worker
- Whether the person is an employee or independent contractor
- Where the employee performs their work
- Which entity is responsible for PAYE registration
- Who approves payroll changes
- How benefits and expenses are reported
- How employee information reaches payroll
- Who handles HMRC notices and corrections
These questions are even more crucial in the case of HR, finance and payroll functions being based across various countries.
Employers can coordinate and manage calculations, tax year changes, statutory payments, reporting deadlines, and employee records using experienced payroll services in their UK operations in one process.
A Practical 2025 Payroll Review Checklist
International employers catching up on UK payroll should review the following areas:
Payroll configuration
- Employer National Insurance rate
- Secondary threshold
- Minimum wage rates
- Statutory payment rates
- Employee tax codes
- National Insurance category letters
Employee records
- Home address and contact details
- Start date
- Pay frequency
- Working hours
- Student loan information
- Leave records
- Benefits and expenses
- Right-to-work documentation
Internal controls
- Payroll approval deadlines
- Change-request process
- Employee data protection
- HMRC submission responsibilities
- Error correction procedures
- Year-end reporting calendar
A payroll review should not be limited to checking whether employees received money. It should confirm that the correct amount was calculated, reported, recorded, and supported.
Keep UK Hiring from Becoming a Payroll Risk
Employers in 2025 had to adapt to the rise in employer contribution, reduction of National Insurance thresholds, rise in minimum pay rates and a new statutory neonatal leave and pay regime.
The remote management of these rules can impose an unneeded strain on the internal HR and finance functions for an international company.
