Understanding the April 2025 National Insurance Changes

From April 6th, 2025, National Insurance costs for employers increased from 13.8% to 15%, while the threshold dropped from £9,100 to £5,000. An increase in the employer's NI allowance from £5,000 to £10,500 helps, but many will still face higher contributions per employee. Additionally, Class 1B contributions have also risen to 15%, increasing overheads significantly.

 

What Salary Sacrifice Actually Means

Salary sacrifice is a voluntary agreement where employees trade part of their gross pay for non-cash benefits — like pension contributions or cycle-to-work schemes. This setup results in lower taxable pay, meaning both the employer and employee pay less in National Insurance while still gaining the same benefits.

 

How Salary Sacrifice Works in Practice

Take pensions, for example: without salary sacrifice, the employee pays £500 into their pension from net salary. With salary sacrifice, their gross salary is reduced by £500, and that amount goes straight into the pension. Both parties then enjoy NI savings.

 

The Financial Benefits Are Clear

Employers could save up to £900 per employee annually. Employees also reduce their own NI contributions. Multiply these savings across a workforce, and the financial impact becomes substantial — all without reducing actual pension value.

 

Eligible Benefits for Salary Sacrifice

Despite recent limitations, options like pensions, low-emission vehicles, workplace nurseries, and bikes with safety gear still qualify. Each brings tax efficiencies when structured correctly.

 

Legal Requirements You Must Follow

It’s critical to follow the rules: update contracts, ensure genuine salary reductions, and never backdate arrangements. These schemes must be implemented before payroll runs. Errors could result in HMRC scrutiny.

 

Why Act Sooner Rather Than Later

The earlier you start, the greater your savings. Delaying means more months of paying higher National Insurance. Don’t let inaction eat into your profits — explore your options now.
