Is sales commission pensionable? Auto-enrolment, qualifying earnings, and the certification trap

Most UK sales orgs assume commission gets pensioned the same way base salary does. It doesn't — or rather, it might, depending entirely on a definition buried in your scheme rules that finance often hasn't read since the day the scheme was set up. The same £45k base + £20k OTE rep can attract anywhere from roughly £1,300 to £1,950 in employer pension contributions per year, just based on which earnings definition the scheme uses. Multiply that by a team of 30, and the wrong choice quietly costs (or under-funds) more than £18,000 a year.

TL;DR

• Commission is "earnings" under section 13 of the Pensions Act 2008, so it counts toward the £10,000 auto-enrolment trigger and the £6,240–£50,270 qualifying earnings band.
• Whether commission is actually pensionable (i.e. attracts contributions) depends on which definition your scheme uses: qualifying earnings, basic pay, or total earnings.
• The three certification "sets" published by DWP (9%/8%/7%) let employers use basic pay or total earnings instead of qualifying earnings — but Set 2 requires aggregate pensionable pay to be at least 85% of total earnings, which high-variable-pay sales teams routinely fail.
• A £45k base + £20k OTE rep produces a ~£630 swing in annual employer contributions depending on which definition you pick.
• If your sales team's OTE mix is 70/30 or more aggressive, Set 2 certification on basic-pay-only is almost certainly non-compliant in aggregate.

What counts as "earnings" for auto-enrolment in the UK?

The statutory definition is unambiguous. Under section 13(3) of the Pensions Act 2008, "earnings" for auto-enrolment purposes include salary, wages, commission, bonuses and overtime, plus statutory sick, maternity, paternity, adoption and shared parental pay. Commission is in the list. Full stop.

That means commission counts when you're working out whether a worker has crossed the £10,000 earnings trigger and whether they sit inside the qualifying earnings band of £6,240 to £50,270 — figures confirmed by The Pensions Regulator for both 2025/26 and 2026/27. A new SDR on £24k base with a £6k commission run-rate is over the trigger; a part-time BDR on £9k base who books a £3k spiff has just become an eligible jobholder.

This is where most finance teams stop reading. They shouldn't. "Earnings" defines who gets auto-enrolled and where the qualifying earnings band bites. It does not by itself define what your scheme treats as pensionable pay. That's a separate decision sitting in your scheme rules — and it's where the cost variation lives.

What are the three definitions of pensionable pay?

UK money-purchase schemes have to meet either the "relevant quality requirement" — 8% of qualifying earnings, of which at least 3% comes from the employer — or one of three certified "alternative quality requirements" set out in DWP's guidance on certifying money purchase pension schemes. The Pensions Regulator's Detailed Guidance No. 4 covers the same territory for trustees and providers.

In plain English, you can use one of four pensionable-pay bases:

The DWP guidance defines "basic pay" as gross earnings excluding bonuses, overtime, commission, shift premium pay and certain job-related allowances. Holiday pay and statutory benefits (SSP, SMP etc.) must be included. So under Sets 1 and 2, commission is explicitly not part of pensionable pay unless your scheme rules go beyond the minimum and add it back in.

Worked example: a £45k base + £20k OTE rep

Let's run the same rep through each definition. Assume Aisha is an AE on £45,000 base, £20,000 variable, hitting 100% of plan. Total earnings: £65,000.

A few things jump out. First, the qualifying-earnings basis is the cheapest employer contribution for this rep, even though it sounds the most generous to employees — because the lower-threshold offset (£6,240) shaves a meaningful chunk off the pensionable base. Second, the gap between the cheapest (qualifying earnings, £1,320.90) and the most generous (total earnings Set 3, £1,950.00) is about £629 per rep per year — roughly 48% more employer cost.

Third, and this is the one finance teams miss: under Set 2, Aisha herself looks fine. The problem is the aggregate test across the whole sales team.

Why does Set 2 trap sales-heavy teams?

Set 2 lets you keep contributions at the statutory 8%/3% level while excluding commission and bonuses from pensionable pay — provided the total pensionable earnings of all relevant jobholders, taken in aggregate, are at least 85% of their total earnings. DWP's guidance is explicit on this: it's an aggregate test across the certified population, recalculated at renewal.

Now think about a typical UK sales org running a 70/30 split (£45k base, £20k OTE — a 69%/31% mix at quota). If reps hit plan, basic pay is only about 69% of total earnings across the team. That's well below 85%. The certificate is invalid the moment commission lands above plan, and TPR can require the employer to make good shortfalls retrospectively where there's been a mis-certification. We have a deeper teardown of how variable mix sits inside UK comp norms in the OTE salary UK guide.

How does commission interact with the qualifying earnings cap?

The qualifying earnings band runs from £6,240 to £50,270 per The Pensions Regulator's published thresholds. Commission paid above £50,270 of total earnings doesn't attract pension contributions on the statutory basis. For an AE who is over-attaining, that creates two practical effects:

1. The over-quota windfall is pensionless. A rep on £45k base who books £30k of commission has £75k of total earnings, but only £44,030 is pensionable under qualifying earnings. The marginal commission pound earned above the cap is invisible to the pension system but still attracts PAYE and Class 1 NIC — covered in our commission tax guide.
2. Lumpy commission distorts pay-reference-period calculations. Most payrolls calculate contributions on a per-pay-period basis, not annualised. A rep who booked a £15,000 quarterly accelerator in March can blow past the monthly equivalent of the upper threshold (£4,189 in 2026/27) within a single payroll. The right answer is to use a 12-month pay reference period or to true up at year-end; the wrong answer is to under-contribute and quietly hope nobody notices.

What about salary sacrifice on commission?

Salary sacrifice can be applied to commission, but only if the sacrifice arrangement is in place before the commission is earned and contractually due — HMRC's Employment Income Manual EIM42750 is the canonical reference on effective salary sacrifice arrangements. In practice, this means a rep can't look at a £15,000 quarterly cheque about to land and retrospectively divert £5,000 into pension; the variation has to be agreed in advance and apply to a future earnings period.

Where salary sacrifice on commission does work, the upside is meaningful: the employer saves Class 1 secondary NIC on the sacrificed amount (15% from April 2025), and the rep avoids primary NIC and income tax on it. Some employers share the employer NIC saving with the rep as an additional pension contribution, which moves the conversation from "how much do we have to contribute" to "how do we use commission to fund a better retirement than the statutory floor allows". This sits alongside the broader employer NIC story for commission, where the 2025 rate change shifted the maths materially.

What should finance teams actually do?

Three practical moves, in order of urgency:

1. Pull the scheme rules and the certificate. Find out which basis you're on — qualifying earnings, Set 1, Set 2, or Set 3. If it's Set 2, get the aggregate ratio of basic pay to total earnings for the relevant jobholder population. If it's under 85%, your certificate is at risk.
2. Model the cost differential. Run the four-basis table above against your actual headcount, not a notional rep. The cost difference between Set 1 and qualifying earnings is the hidden subsidy or hidden cost in your current setup. We sketch the full year-end audit flow in the end-of-year commission checklist.
3. Decide whether to recertify or move to qualifying earnings. If your sales team has shifted toward higher OTE mixes since the scheme was set up, the original certification may no longer fit. Moving to a qualifying-earnings basis is often the simplest answer for variable-pay-heavy populations — it's the statutory default and avoids the aggregate test entirely.

The through-line: the auto-enrolment file is one of the few payroll obligations where the definition matters more than the rate. The headline 8% vs 7% vs 9% gap is a sideshow next to which earnings number you multiply it by.

Frequently Asked Questions

Is commission pensionable in the UK?

Commission is always "earnings" for auto-enrolment eligibility purposes under section 13 of the Pensions Act 2008, but whether it is pensionable — meaning contributions are actually paid on it — depends on which definition the scheme uses. On a qualifying-earnings basis, commission is pensionable up to the £50,270 upper threshold. On a certified basic-pay basis (Sets 1 and 2), commission is excluded from pensionable pay.

Does commission count toward the £10,000 auto-enrolment earnings trigger?

Yes. The £10,000 earnings trigger uses the wide statutory definition of earnings, which expressly includes commission, bonuses and overtime. A part-time or junior rep whose base salary is below £10,000 can still cross the trigger once commission is added, and the employer's duty to auto-enrol applies from the pay-reference period in which the trigger is crossed.

What is the 85% test in Set 2 certification?

Under Set 2, an employer can contribute 8% of basic pay (rather than 8% of qualifying earnings) as long as the aggregate pensionable pay of the certified jobholder population is at least 85% of their aggregate total earnings. Sales teams with average commission shares above roughly 15% of total pay routinely fail this test, which invalidates the certificate and can trigger retrospective contribution top-ups.

Can a rep use salary sacrifice on commission payments?

Yes, but only if the salary sacrifice variation is in place before the commission is contractually earned. HMRC will not accept a retrospective sacrifice of commission already due. Where the arrangement is structured correctly, both employer NIC and employee tax/NIC are saved on the sacrificed amount, which can make commission-funded pension contributions materially more efficient than ordinary auto-enrolment.

What happens to commission earned above the £50,270 upper qualifying earnings threshold?

On a qualifying-earnings basis, no pension contributions are payable on earnings above £50,270 per year. Commission that pushes a rep above the cap is still fully subject to PAYE and Class 1 NIC, but doesn't generate pension contributions. Schemes using Set 3 (total earnings) or a bespoke pensionable-pay definition that exceeds basic pay can cover this commission, but at the cost of a higher contribution rate or a richer benefit promise.
