Workplace Pension Deductions: Qualifying Earnings
Most UK employees are auto-enrolled into a workplace pension. The legal minimum is 8% of qualifying earnings, split between employee, employer, and HMRC tax relief. But how that 8% feels in your take-home pay depends entirely on whether your employer uses relief at source, net pay, or salary sacrifice.
Quick answer
Eligible workers aged 22 to State Pension age, earning over £10,000 a year and ordinarily working in the UK are normally automatically enrolled. For a qualifying-earnings scheme, the usual minimum is 8% total with at least 3% from the employer. Your cash deduction depends on the pension method and employer contribution.

Who gets auto-enrolled
Automatic enrolment normally applies to workers aged 22 to State Pension age who earn over £10,000 a year and ordinarily work in the UK. Employers assess earnings in the relevant pay period and can use permitted postponement, with notice.
Workers aged 16–74 outside the automatic-enrolment group may have a right to opt in or join. If earnings exceed £6,240 annually, an eligible opt-in request normally carries an employer-contribution duty; at or below that level, a right to join does not require employer contributions.
Being over 50 does not itself move someone out of automatic enrolment. Check the Pensions Regulator's age and earnings categories.
The 8% minimum and how it splits
For the usual qualifying-earnings basis in 2026/27, minimum total funding is 8% of earnings between £6,240 and £50,270, including at least 3% from the employer. Some schemes use a different certified basis. A higher employer payment can reduce the member amount needed to reach the total.
At £30,000 with the employer paying 3%, qualifying earnings are £23,760. The annual illustration is £712.80 employer + £1,188 gross member funding = £1,900.80.
Under relief at source, the member pays £950.40 from net pay and the provider adds £237.60 basic-rate relief. Under net pay, £1,188 is deducted before Income Tax. Salary sacrifice instead becomes an employer contribution in exchange for lower salary. The 4% cash deduction is therefore a relief-at-source example, not a universal rule.
How the delivery method changes your pay
Compare the same gross pension funding when looking at different methods. Assume England in 2026/27, £30,000 salary, NI category A, 5% of qualifying earnings (£1,188) and no loans or other adjustments. The table isolates that contribution, with employer funding held constant.
| Method | Gross funding | Take-home reduction |
|---|---|---|
| Relief at source | £1,188 | £950.40 |
| Net pay | £1,188 | £950.40 |
| Salary sacrifice | £1,188 | £855.36 |
Salary sacrifice's additional employee NI saving is £95.04 a year, or £7.92 monthly equivalent. If 5% applies to the full £30,000 salary instead, the £1,500 contribution produces an extra NI saving of £120 a year (£10 a month). Actual period rounding and scheme rules may differ.
Higher-rate relief under relief at source may require a claim; net pay gives Income Tax relief through payroll. Salary sacrifice depends on employer availability and minimum-wage compliance. See the pension-method comparison for the full assumptions and future-rule note.
Which pension amount to enter in the calculator
The take-home pay calculator applies a percentage to your full salary. If your scheme instead uses qualifying earnings or another pay basis, choose Fixed (£) and enter your monthly employee contribution. Ask payroll which earnings and contribution method your scheme uses.
For relief at source, enter the amount you pay before the provider adds tax relief. For net pay, enter your contribution before Income Tax relief. For salary sacrifice, enter the salary you give up. Do not add the employer’s separate contribution to your input. Compare the same gross pension funding when comparing methods.
Net pay pensions when earnings are below the tax allowance
If your earnings are below or around your tax allowance, a net pay contribution may receive no immediate Income Tax relief on some or all of the payment. HMRC’s low earner’s pension payment can address that difference from relief at source.
HMRC assesses eligibility after each tax year from 2024/25 onwards and says you do not need to apply: it will contact eligible members. This is separate from the monthly payslip calculation, so do not assume a missing payslip top-up is an error or that payment is due on the next payday. Keep your pension and pay records and follow HMRC’s current guidance.
Opting out, opting back in, and re-enrolment
The statutory opt-out window is normally one month from the relevant enrolment information, not a blanket 30-day period. A valid opt-out within that window refunds contributions. After it, leaving active membership follows scheme rules and contributions usually remain invested.
Employers reassess eligible staff at their re-enrolment date, normally around every three years. Exceptions apply, including discretion for some people who left recently.
You can request to opt in again, but if you already opted in and then stopped membership in the previous 12 months, the employer may not have to action a repeat request until that period ends. A next-payday restart is not guaranteed.
Changing jobs normally leaves the old pot with its provider while the new employer assesses you separately. Before transferring, check charges, guarantees and any safeguarded benefits.
When to consider contributing more
Start with the employer's matching rules, your budget and when you need access to the money. There is no single contribution percentage that guarantees a particular retirement lifestyle.
Tax relief and annual allowances depend on your circumstances. The standard annual allowance is £60,000, but tapering or the money purchase annual allowance can reduce it; personal contributions also have earnings-related relief limits. Carry-forward has conditions.
For example, £5,000 gross funding wholly relieved at 40% costs £3,000 after all Income Tax relief, before any NI saving. That example does not cover Scottish rates or an allowance-taper interaction. Check your scheme and consider regulated advice for large or complex changes.
What to check
- Check your most recent payslip for a pension line — note whether it appears before or after the tax calculation.
- Confirm with HR or your scheme provider whether contributions are relief at source, net pay, or salary sacrifice.
- Verify the contribution percentage matches the 8% minimum, or higher if your employer offers a more generous match.
What to do next
- Use the calculator’s fixed monthly amount if your scheme uses qualifying earnings rather than full salary.
- Ask HR which pension method and earnings basis apply, and whether employer NI savings are shared.
- Check the Pensions Regulator guidance if enrolment or employer contributions appear wrong.

Common questions
- How much do I have to pay into a workplace pension?
- For a usual qualifying-earnings scheme in 2026/27, the total minimum is 8% on earnings between £6,240 and £50,270, including at least 3% from the employer. The remaining funding and your cash deduction depend on the employer contribution and pension method. A 4% net deduction is a common relief-at-source example, not a universal rule.
- Can I opt out of auto-enrolment?
- A valid opt-out within the statutory one-month window normally refunds contributions. Leaving later follows scheme rules. Employers reassess eligible workers for re-enrolment normally around every three years, with exceptions.
- What happens to my workplace pension when I change jobs?
- It stays with the original provider — pensions do not automatically follow you. You can leave it where it is, transfer it into your new workplace scheme, or transfer it into a personal pension.
- Why is the pension figure on my payslip different to my pension statement?
- It depends on the delivery method. Net-pay arrangements deduct the gross figure; relief at source deducts the net amount and the provider adds basic-rate top-up later; salary sacrifice changes the headline salary itself.
