PAYROLL UNPACKED – WEEK 5
WHERE DID MY PENSION CONTRIBUTION ACTUALLY GO?
A pension deduction on your payslip does not always tell you the full amount being paid into your pension.
That is because workplace pension contributions can be calculated in different ways, and the method used to give you tax relief changes what you actually see on your payslip.
For this week’s example, I’ve used a monthly salary of £3,000 and an automatic-enrolment pension based on qualifying earnings.
For 2026/27, the monthly qualifying earnings band runs from £520 to £4,189. So on monthly pay of £3,000, the pension calculation in this example is based on:
£3,000 - £520 = £2,480
The statutory minimum contribution requirement is at least 8% overall, with at least 3% coming from the employer. The Pensions Regulator
In the example shown, the scheme uses relief at source.
A 5% gross employee contribution on £2,480 is £124.
But that does not mean £124 is deducted from the employee’s pay.
Under relief at source, the employee pays £99.20 through payroll and the pension provider claims £24.80 basic-rate tax relief from HMRC.
The employer then contributes £74.40, based on 3% of the same qualifying earnings.
So the figures are:
Employee deduction from pay: £99.20
Tax relief added by pension provider: £24.80
Employer contribution: £74.40
Total into the pension pot: £198.40
That is why somebody can look at their payslip, see a £99.20 pension deduction, and assume something is missing when in fact considerably more is being invested.
Under relief at source, the employee contribution is deducted after PAYE has been calculated and the pension provider claims the basic-rate tax relief separately. GOV.UK
A net pay arrangement works differently.
With net pay, the full employee pension contribution is deducted from gross pay before PAYE Income Tax is calculated.
Using the same example, £124 would normally be deducted through payroll and taxable pay would be reduced accordingly. The pension provider does not then add another basic-rate tax-relief amount because the tax relief has already been given through payroll. GOV.UK
National Insurance is different again.
Ordinary employee pension contributions do not reduce NIable pay simply because the scheme uses net pay. NICs are normally calculated on gross earnings before those pension deductions. Salary sacrifice is a separate arrangement and works differently. GOV.UK
There is one other important point.
Not every workplace pension uses qualifying earnings.
Some schemes use basic pay, some use pensionable pay defined in the scheme rules, and some employers contribute above the statutory minimum. So you cannot simply look at somebody’s salary, multiply it by 5%, and assume that is what should appear on their payslip. The scheme rules matter. The Pensions Regulator
That is the real message from this week’s Payroll Unpacked:
Your pension deduction is only one part of the calculation.
If you want to understand what is actually going into your pension, you need to know:
the earnings basis being used,
the employee contribution rate,
the employer contribution rate, and
whether the scheme operates relief at source or net pay.
