Salary sacrifice and National Insurance changes from April 2029

Salary sacrifice changes move from Budget proposal to enacted law

The proposed changes to salary sacrifice arrangements were first announced during the Autumn Budget 2025, when the Government outlined plans to restrict the National Insurance advantages linked to certain salary sacrifice arrangements from April 2029.

At the time, many employers viewed the announcement as an early policy proposal that would still require consultation and parliamentary approval. That position has now changed.

On 29 April 2026, the National Insurance Contributions (Employer Pensions Contributions) Act 2026 received Royal Assent and officially became law. The legislation introduces a significant change to how National Insurance Contributions (NICs) savings will apply to salary sacrifice arrangements linked to pension contributions from 6 April 2029.

Under the new rules, only the first £2,000 of contributions made through salary sacrifice each tax year will remain exempt from NICs. Contributions above that threshold will become subject to both employer and employee NICs.

For employers, this marks an important shift from proposed policy into confirmed legislation. Businesses now have greater certainty around the future direction of payroll taxation, remuneration planning and employment costs.

The changes arrive at a time when many organisations already face rising payroll costs, higher employer NIC rates and increased HMRC scrutiny around payroll compliance and reporting accuracy.

What is salary sacrifice?

Salary sacrifice allows an employee to exchange part of their gross salary for a non-cash benefit provided by their employer. One of the most common uses of salary sacrifice arrangements is pension contributions.

Because the sacrificed salary is not treated as taxable pay for NIC purposes under current rules, both the employer and employee can benefit from National Insurance savings.

Many employers have used salary sacrifice arrangements because they can:

– improve tax efficiency for employees
– reduce employer NIC liabilities
– support employee retention strategies
– improve overall reward packages
– assist with long-term financial planning

Businesses reviewing current arrangements may also wish to consider the wider tax and compliance implications of salary sacrifice schemes. Our article on salary sacrifice pitfalls for employers explores some of the common areas employers should monitor.

The Government believes the current structure disproportionately benefits higher earners and has argued that reform is necessary to make the system fairer and more sustainable.

What the National Insurance changes mean for employers

From April 2029, employers will still be able to offer salary sacrifice arrangements. However, NIC relief will only apply to the first £2,000 sacrificed each year per employee.

This means many employers could face higher payroll costs and additional administrative obligations.

Higher employer NIC costs

Businesses with employees contributing above the £2,000 threshold could see increased employer NIC liabilities from 2029 onwards.

For larger employers and businesses with higher-paid workforces, the financial impact could become significant over time, particularly alongside other increases to employment costs already introduced in recent years.

Increased payroll administration

Payroll teams will need systems capable of monitoring salary sacrifice contributions accurately and applying NICs where thresholds are exceeded.

Businesses already preparing for wider payroll reforms may also find it useful to review the upcoming mandatory payrolling of benefits in kind from April 2027 and how this could affect capturing taxable expenses and benefits data, calculations and reporting processes and cashflow.

Review of remuneration strategies

Many businesses use salary sacrifice arrangements as part of wider reward and retention packages. Employers may now need to reassess how they structure benefits and tax-efficient remuneration going forward.

Owner-managed businesses may also need to revisit director remuneration strategies where salary sacrifice forms part of wider extraction planning.

Employers reviewing remuneration structures should also understand whether employee benefits are taxable and how changing HMRC rules may affect reporting obligations.

What the changes mean for employees

Employees who contribute more than £2,000 through salary sacrifice arrangements may see higher NIC deductions from April 2029, which could reduce overall take-home pay compared to current arrangements.

For some employees, this may mean salary sacrifice becomes less tax-efficient than it is today, particularly for higher earners or those making larger pension contributions through payroll.

However, the legislation does not remove all tax advantages linked to salary sacrifice or employer pension contributions.

Potential reduction in take-home pay

Where contributions exceed the future £2,000 threshold, employees will pay NICs on amounts above the limit. The exact financial impact will depend on earnings levels, contribution amounts and future NIC rates at the time the rules take effect.

Employees who currently benefit from larger salary sacrifice arrangements may therefore notice a reduction in monthly net pay from April 2029.

Pension saving may still remain tax-efficient

Although NIC treatment will change, pension contributions will still benefit from Income Tax relief under existing rules. For many individuals, pension saving is therefore still likely to remain one of the more tax-efficient long-term planning options available.

Some employees may remain unaffected

Many employees may not exceed the proposed £2,000 threshold and could therefore see little or no direct financial impact from the reforms.

Lower and middle earners making standard workplace contributions may continue to benefit from the existing structure without significant change.

A limited window remains before the reforms take effect

As the new rules will not apply until April 2029, employers and employees still have a period of time to benefit from the current NIC advantages available through salary sacrifice arrangements.

Some advisers have suggested that businesses and employees may wish to review contribution levels ahead of implementation, particularly where employers offer matched contributions as part of wider remuneration packages. Early planning may help employers and employees maximise existing efficiencies while the current rules remain in place.

Wider tax planning considerations still apply

Salary sacrifice arrangements can still help reduce adjusted net income, which may remain relevant for:

– Child Benefit planning
– Tax-Free Childcare eligibility
– personal allowance tapering
– higher-rate tax planning

Employees may therefore still benefit from reviewing their wider remuneration and tax planning arrangements despite the future NIC changes. Individuals requiring support with wider personal tax planning may also benefit from reviewing our self assessment and personal tax compliance services.

Why businesses should start planning now

Although the reforms will not take effect until April 2029, employers should begin assessing the potential impact now rather than waiting until implementation approaches.

Forward planning gives businesses time to review:

Existing salary sacrifice arrangements

Employers should identify which employees may exceed the future threshold and estimate the possible payroll cost impact.

Future payroll budgets

Businesses may need to account for increased employer NIC liabilities within long-term workforce and operational planning.

Payroll software and compliance systems

Payroll systems and reporting processes may require updates as HMRC releases further operational guidance before implementation.

Director remuneration planning

Owner-managed businesses may benefit from reviewing alternative remuneration structures and wider tax planning strategies ahead of the reforms taking effect.

Workforce communication strategies

Clear communication will become increasingly important as employers prepare employees for future payroll and NIC changes.

The wider payroll compliance landscape

The salary sacrifice reforms arrive during a period of continued change for UK employers.

Alongside these new rules, businesses are also managing:

– higher employer NIC rates
– lower secondary NIC thresholds
– increased payroll reporting requirements
– evolving umbrella company compliance rules
– growing HMRC scrutiny around PAYE accuracy
– wider employment tax compliance pressures

For many businesses, payroll can no longer operate solely as an administrative function. Employers increasingly require joined-up payroll, tax and advisory support to manage compliance, forecasting and workforce costs effectively.
