Facing the 2025 National Insurance hikes
Since April 2025, UK employers face a challenging new reality: employer National Insurance (NI) contributions have jumped from 13.8% to 15%. The threshold has also dropped from £9,100 to £5,000 per year. The drop means employers must start paying contributions sooner and on a greater percentage of their gross salary. So, more tax on a greater share of every salary, just as budgets are already strained across sectors like hospitality, care, education, and non-profits. Over 940,000 employers are directly affected, and nearly half say these tax hikes are influencing recruitment decisions, while a third freeze or limit pay growth. For many HR professionals, this represents the most significant pressure on workforce costs in a decade.
Why Salary Sacrifice Is a game-changer
Salary sacrifice provides a proven, government-backed solution. When employees agree to 'sacrifice' a portion of their gross salary for a direct pension contribution, both they and their employer pay less in National Insurance. What’s more, these schemes are robust: they’re HMRC-compliant, work with auto-enrolment, and integrate easily with payroll systems. This flexible model means the savings can be substantial, a mid-sized business can save thousands of pounds per year by implementing pension salary sacrifice. Smart adoption of salary sacrifice gives HR leaders the ability to reinvest savings into staff rewards, protect jobs, and strengthen overall benefits.
The long-term view: Your strategic opportunity
The NI rise isn’t a temporary measure; it’s a structural, permanent shift. All sectors are under pressure and businesses simply can’t absorb these increased costs through efficiencies alone. Even with an increased Employment Allowance, most organisations will find it quickly used up. That’s why leading HR teams are transforming salary sacrifice from a ‘nice to have’ into a core part of long-term budget and people planning.
Rolling out a simple opt-out Pension Salary Sacrifice arrangement sends a powerful signal: that you’re adapting fast, controlling costs, and making a lasting difference for your people and financial sustainability.
