April 2025 brought the most sustained and structural change to employer National Insurance contributions in over a decade. The rate increased and the threshold dropped simultaneously, creating a compounding effect on payroll costs across every sector. Furthermore, a major change to Employment Allowance went largely unreported. Many employers are consequently paying more than necessary, or missing relief they are entitled to. Understanding all three changes together is therefore essential for any business with staff on the payroll.

What Changed With Employer National Insurance From April 2025?
Three changes took effect on 6 April 2025. Two increased the cost of employing staff directly. The third offered partial relief against those rising costs. First, the employer National Insurance rate rose from 13.8% to 15%. Second, the secondary threshold dropped from nine thousand one hundred pounds to five thousand pounds per year. This is the point at which employer NI begins. Third, however, the Employment Allowance more than doubled from five thousand to ten thousand five hundred pounds.
Many employers know about the first two changes. Far fewer are aware of the third. As a result, a significant number of businesses are either overclaiming, underclaiming, or not claiming Employment Allowance at all.
How Much More Are Employers Actually Paying After the Rate Change?
The combined effect of a higher rate and a lower threshold is larger than either change alone. Consider an employee earning twenty-five thousand pounds per year. In 2024 to 2025, employer NI applied to fifteen thousand nine hundred pounds above the old threshold. Moreover, it applied at 13.8%, producing a bill of approximately two thousand one hundred and ninety pounds.
From April 2025, however, NI applies to twenty thousand pounds above the new threshold, at 15%. The resulting bill is three thousand pounds. That is an increase of around eight hundred pounds per employee. For a business with ten employees at similar pay, that is consequently over eight thousand pounds more per year. Hospitality, retail and construction consequently face the sharpest pressure. Wage bills are large and margins are already tight in those sectors.
What Is the Employment Allowance in 2025 and Who Actually Qualifies?
The Employment Allowance lets eligible employers reduce their annual employer National Insurance bill. Eligible businesses can reduce it by up to ten thousand five hundred pounds. This figure is often misreported. Indeed, several well-known accounting guides still show the old five thousand pound figure.
The allowance increased from five thousand to ten thousand five hundred pounds on 6 April 2025. In addition, the cap blocking employers with a Class 1 NI bill above one hundred thousand pounds has been removed. All eligible employers can now apply.
However, important exclusions still apply. Furthermore, connected companies face a specific restriction. Only one company within a connected group can claim the allowance for a given tax year. That status is determined on 6 April each year. Subsequent changes in the relationship between companies do not affect eligibility for that year.
Does the Employment Allowance Apply to Single Director Companies?
This is one of the most misunderstood areas of employer National Insurance compliance. A sole director company where the director is the only employee above the secondary threshold cannot claim Employment Allowance. However, the position changes as soon as at least one other employee is paid above that threshold. For example, if the company hires a part-time employee paid above five thousand pounds annually, it becomes eligible. Furthermore, that eligibility applies to the full tax year.
Moreover, the allowance is not restricted to companies. Charities, community amateur sports clubs and other eligible organisations can also claim. However, businesses doing mainly public sector work cannot claim. Employers of domestic staff and those with IR35 off-payroll workers are also excluded.
How Does Higher Employer National Insurance Affect Director Salary Planning?
The increase in employer NI has a direct impact on the optimal salary level for company directors. Many directors draw a salary just above the personal allowance threshold and take the remainder as dividends. However, with the secondary threshold now at five thousand pounds, employer NI applies earlier than before. As a result, the calculation of the most tax-efficient salary level has shifted for the 2025 to 2026 tax year.
Furthermore, directors who previously set their salary at nine thousand one hundred pounds are now generating an employer NI liability. That liability did not exist under the old rules. Consequently, reviewing director salary and dividend structures in light of the new thresholds is not optional. It is a straightforward planning step that prevents unnecessary cost.
Can Salary Sacrifice Reduce Your Employer National Insurance Bill?
Salary sacrifice is one of the most effective and legal ways to reduce employer National Insurance contributions. Under a salary sacrifice arrangement, an employee agrees to exchange part of their gross salary for a non-cash benefit. Because the benefit replaces salary, the employer’s NI liability is calculated on a lower wage. Moreover, the employee also pays less NI and income tax. Common qualifying benefits include pension contributions, electric vehicle schemes, and cycle to work arrangements.
Pension salary sacrifice cuts the employer NI bill on the sacrificed amount. Two thousand pounds per year of sacrifice, for instance, saves three hundred pounds. Furthermore, where multiple employees participate, the aggregate saving is substantial. However, arrangements must be properly documented. Employee take-home pay must not fall below the National Living Wage.
What Payroll Compliance Risks Follow the Threshold Change?
The secondary threshold reduction from nine thousand one hundred to five thousand pounds has created a new compliance risk. Numerous employers have not fully assessed its reach. As a result, businesses with large numbers of part-time or seasonal staff must recalculate payroll exposure. Part-time employees who previously fell below the threshold now generate an employer NI liability. Furthermore, businesses using manual payroll calculations are particularly vulnerable to error.
HMRC receives payroll data in real time through RTI submissions. Consequently, discrepancies between reported liabilities and actual payments are identified quickly. In addition, incorrect Employment Allowance claims are a growing area of HMRC attention. A sole director company with no other employees that incorrectly claims the allowance risks an HMRC assessment. Penalties may also apply. Therefore, a payroll review before each tax year is not a formality. It is a compliance necessity.
