Salary sacrifice

Does salary sacrifice — reduce your state pension?

The concern is legitimate but affects a narrow group. For most workers, sacrifice would need to be implausibly large to threaten a qualifying NI year.

Why this concern exists

The new State Pension is built on National Insurance qualifying years. You need 35 qualifying years to receive the full amount (£221.20 per week in 2025/26); you need at least 10 years to receive anything at all.

Salary sacrifice reduces your contractual gross salary. Because National Insurance is calculated on gross pay, it also reduces your NI-able earnings. This raises a reasonable question: could sacrifice reduce NI-able pay enough to prevent a year from counting as a qualifying year?

The answer is yes — in theory. In practice, for most workers, the threshold is so far below normal earning levels that sacrifice of any realistic scale does not come close to it.

The Lower Earnings Limit: £6,396 in 2025/26

A qualifying NI year requires your earnings to reach the Lower Earnings Limit (LEL) for National Insurance purposes. For 2025/26, the LEL is £6,396 per year — £533 per month, or £123 per week.

Reaching the LEL does not mean you pay NI. You only start paying NI once your earnings exceed the Primary Threshold (£12,570). But earnings between the LEL and the Primary Threshold are treated as if NI contributions have been made — those weeks count for state pension purposes without any actual NI deduction appearing on your payslip.

This design means that part-time workers or lower earners earning modestly above the LEL still build qualifying years. And it means that to threaten a qualifying year through salary sacrifice, you would need to reduce NI-able pay below £6,396.

In practice: almost never a problem for most workers

Take a worker earning £20,000 per year. To lose a qualifying year through salary sacrifice, they would need to sacrifice enough to take their NI-able pay below £6,396 — a sacrifice of £13,604, or 68% of salary. No employer pension scheme operates at that sacrifice level; most cap sacrifice well below 50% of salary, and the NMW floor would intervene long before the LEL was reached.

At average UK wages of around £35,000, the sacrifice required to breach the LEL would be over £28,600 — entirely implausible.

Even for a worker on the current National Living Wage (£12.21/hour, ~£23,840 for a 37.5-hour week), the salary after maximum permissible sacrifice — which cannot take pay below the NMW floor of ~£23,840 — is still well above the £6,396 LEL.

The LEL concern and the NMW floor are two separate constraints. In practice, the NMW floor always binds first. An employer's salary sacrifice system cannot legally allow sacrifice below minimum wage, and minimum wage is always substantially above the LEL. The two constraints work together to make LEL breach through sacrifice effectively impossible for anyone in full-time employment.

The edge case where it could matter

There is a narrow group where the concern is real rather than theoretical:

Very low-earning part-time workers. Someone working 10 hours per week at NMW earns around £6,349 per year — already close to the LEL. Any sacrifice arrangement could push them below the qualifying threshold. Employers should (and under auto-enrolment must) assess whether sacrifice is appropriate for workers in this situation, but it is worth checking your own position if you work reduced hours.

Workers near the LEL who have paused contributions and are relying on multiple jobs. If you have earnings from multiple employments, each is assessed separately for NI purposes. Sacrifice in one job does not affect the NI calculation in another. But if your only employment is low-hours and you sacrifice a proportion of it, the combined effect could be a year that does not qualify.

Workers in the reference year for contracted-out schemes. This is now largely historic — contracting out ended in 2016 — but older NI records may reflect periods of reduced state pension accrual that some workers confuse with a current sacrifice effect.

Checking your NI record

HMRC maintains your NI record and flags any years that are incomplete or non-qualifying. You can check yours via the Government Gateway at gov.uk, or use the state pension forecast calculator to see your projected state pension and identify any gaps.

Gaps in your NI record can sometimes be filled by paying voluntary Class 3 NI contributions. The deadline for filling gaps from 2006/07 onwards has been extended several times; check current deadlines on gov.uk as they are subject to change.

For most workers running a salary sacrifice arrangement, the state pension impact is zero. The concern is legitimate as a conceptual question — NI is affected — but the practical answer in almost all cases is that the numbers are not close to mattering.
