The Payroll Compliance Changes You Need to Prepare For (2026–2027)

Between April 2026 and April 2027, UK employers will face one of the most significant waves of payroll and employment compliance changes in recent years. A combination of legislative reforms, HMRC policy updates and employment rights changes will impact how businesses manage payroll, employee benefits, statutory entitlements and workforce scheduling.

For many organisations, the risk is not just compliance penalties. These changes will fundamentally alter how payroll, HR and workforce management systems interact.

Many UK SMEs are not fully prepared. In fact, many have not yet heard about the full scale of the changes coming. Understanding what is ahead and preparing early will be critical for maintaining compliance, controlling costs and avoiding operational disruption.

Why Payroll Compliance Is Becoming More Complex

Payroll used to be primarily about calculating wages, tax and National Insurance.

Today it sits at the centre of several regulatory systems:

• HMRC tax reporting
• Employment law
• Statutory benefits administration
• Pension compliance
• Benefits in Kind reporting
• Workforce scheduling and contracts

Because of this overlap, policy changes rarely affect just one system. A change to employment law can quickly create payroll reporting obligations, new statutory payments, or tax implications.

This is exactly what is happening with the upcoming reforms.

Businesses will need payroll systems that can adapt quickly, and many organisations are turning to specialist payroll providers to manage this complexity.

Key Payroll Compliance Changes Coming Between 2026 and 2027

Below are the most important regulatory developments that employers should already be planning for.

1. Statutory Sick Pay (SSP) Reform

One of the most significant employment law changes expected during this period is the reform of Statutory Sick Pay. Proposals linked to wider employment rights reforms suggest several possible changes:

Removal of waiting days: Currently employees must wait three days before SSP starts. Reforms are expected to remove this waiting period, meaning employers will be required to pay SSP from day one of sickness absence.

Eligibility changes: Current SSP eligibility requires employees to earn at least the Lower Earnings Limit. Future reforms may expand eligibility to cover more low-income or irregular workers.

Payroll impact: These changes will create:

• Increased SSP payroll costs
• More frequent SSP processing
• Greater need for absence tracking integration
• Higher reporting complexity
• Businesses relying on manual payroll systems may struggle to manage these changes efficiently.

2. Mandatory Payrolling of Benefits in Kind (BiK)

Another major compliance shift is the move toward mandatory payrolling of Benefits in Kind.

Currently many employers report benefits such as:

• Company cars
• Private medical insurance
• Interest-free loans

using P11D forms submitted after the tax year.

HMRC is moving towards a system where most benefits must instead be taxed in real time through payroll.

What this means for employers

Instead of year-end reporting:

• Benefits must be calculated each pay period
• PAYE tax adjustments must be applied monthly
• Real-time reporting must include benefit values

Operational challenges

Many payroll systems currently treat benefits separately from salary calculations. Mandatory payrolling will require:

• updated payroll software
• integration with HR benefits systems
• more frequent benefit valuation calculations

Businesses with company car schemes or medical insurance programmes will need to prepare early.

3. Tax Adviser Registration Requirements

Another compliance development affecting payroll operations is new registration rules for tax advisers and agents interacting with HMRC systems.

HMRC is tightening oversight of tax agents to reduce fraud and improve reporting transparency.

This will impact:

• payroll providers
• outsourced payroll teams
• accounting firms handling payroll

Potential requirements may include

• mandatory agent registration
• enhanced identity verification
• additional authorisation procedures for PAYE submissions

For businesses outsourcing payroll, this means ensuring their provider meets the updated HMRC requirements.

4. Zero-Hours Contract Reform

One of the most operationally disruptive reforms is the expected regulation of zero-hours and irregular contracts.

The UK government has proposed reforms that could introduce:

• rights to guaranteed hours after a reference period
• greater notice requirements for shift scheduling
• compensation for cancelled shifts

Payroll implications

These reforms will force payroll and workforce scheduling systems to work together more closely.

Payroll teams will need to handle:

• variable hours adjustments
• compensation payments for cancelled shifts
• revised holiday pay calculations
• new reporting obligations

Industries heavily dependent on flexible labour such as hospitality, retail and logistics will face the biggest operational impact.

5. Increased Real-Time Reporting Expectations

HMRC continues to expand Real Time Information (RTI) requirements.

While RTI is already standard for PAYE reporting, further refinements may require:

• more granular payroll reporting
• faster submission timelines
• improved data accuracy requirements

This trend reflects HMRC’s broader goal of creating a near real-time tax administration system.

Businesses with fragmented payroll processes or legacy systems may struggle to meet these expectations.

Why Many Businesses Are Not Ready

Despite the scale of these changes, many organisations remain unprepared.

Common challenges include:

Lack of awareness: Many HR and finance teams are focused on day-to-day operations and are unaware of upcoming regulatory changes.

Legacy payroll systems: Older payroll platforms may not support:

• payrolled benefits
• flexible workforce structures
• integrated HR data

Fragmented HR and payroll systems: When HR, benefits administration and payroll systems operate separately, compliance becomes difficult.

Skills shortages: Payroll is a specialised discipline, and compliance expertise is becoming harder to find internally.

How Employers Should Prepare Now

Businesses should begin preparing for these changes well before the legislation comes into effect.

1. Review your payroll technology

Assess whether your payroll software can support:

• benefit payrolling
• flexible worker scheduling
• automated statutory payment calculations

2. Align HR and payroll processes

Employment contracts, benefits administration and payroll reporting must be closely integrated.

3. Audit employee benefits

Identify which benefits will need to move to real-time payroll reporting.

4. Review workforce contracts

Companies using casual or zero-hours workers should review how potential reforms could affect shift scheduling and payroll calculations.

5. Consider payroll outsourcing

Outsourced payroll providers specialise in compliance monitoring and system updates.

This can significantly reduce compliance risk and administrative burden.

The Strategic Role of Payroll in Modern Businesses

Payroll is no longer just an administrative function. It has become a core compliance and risk management system.

As employment laws evolve and HMRC reporting becomes more sophisticated, businesses need payroll systems that can adapt quickly. Companies that prepare early will not only remain compliant but also gain operational efficiency and financial clarity.

Those that delay preparation may face costly system upgrades, compliance penalties and operational disruption.

Preparation should begin now

The period between 2026 and 2027 will bring one of the most complex regulatory shifts UK payroll teams have seen in years.

From SSP reforms and mandatory payrolling of benefits to zero-hours contract regulation and enhanced tax reporting requirements, employers will need to rethink how payroll integrates with HR and workforce management.

Organisations that proactively review their payroll systems, processes and compliance strategies will be best positioned to navigate the changes smoothly and avoid unnecessary risk.
