A new paper from the Society of Pension Professionals puts an exact number on something most accountants have suspected for years without ever seeing it written down: only 4% of the UK's wholly self-employed are currently saving into a pension. That figure is not a provider's marketing survey. It comes from the Pensions Commission's own interim report — the body government reconvened to work out why Britain is undersaving for retirement. For a profession that spends every January staring at exactly the population this concerns — sole traders, contractors, freelancers filing a Self Assessment return — the more interesting line in the SPP's paper is not the 4%. It is where the paper looks for a fix.
Read past the headline and the SPP's recommendations point, more than once, at the tax system and at the infrastructure that already touches self-employed income — banks, platforms, the annual filing cycle itself. Whether or not any of that becomes policy, the direction of travel is the one that produced Making Tax Digital: government looking at who already has visibility of self-employed income, and asking whether that visibility can be put to a second use. An accountant does not need to wait for a Pensions Commission recommendation to become law to act on that visibility. The Self Assessment return already shows, unambiguously, whether a pension contribution has been claimed — or has never once appeared.
What the SPP paper found
The paper, titled The Missing Millions: Rethinking Pension Policy for the Self-employed, was published on 22 September 2026 and sets out to answer a single question: why does pension saving among the self-employed remain so far behind employees, and what should change about it? Its evidence base is the Pensions Commission's interim report, Pensions 2050: Evidence and Future Priorities, published 19 May 2026, which found that just 4% of wholly self-employed workers are currently contributing to a pension — a structural gap the Commission itself flagged as one of the clearest failures of the current system.
Martin Willis, chair of the SPP's Self-employment Working Group, frames the problem in terms of what changed for everyone else and never changed for this group: "Automatic enrolment changed the default to ensure millions more employees save for retirement. But millions of people who work for themselves have never benefited from that same principle." The paper's recommendations follow directly from that framing. They range from using the tax system to create a default saving route, through behavioural prompts and micro-saving options, to more structural proposals — flexible 'autosave' models linked to income via banks and platforms, expanding defined contribution master trusts or a state-backed scheme, and collective defined contribution arrangements. A separate, more practical strand asks for continuity: a way of carrying pension saving forward when someone moves from employment into self-employment, rather than the current pattern where contributions simply stop the day PAYE does.
Why the gap is structural, not a failure of willpower
Automatic enrolment works because it runs through the employer. A business is legally required to enrol eligible staff into a workplace scheme and contribute alongside them, and the employee has to actively opt out if they want no part of it. Inertia does the rest — most people who are enrolled simply stay enrolled. None of that machinery exists for someone who works for themselves. There is no employer to do the enrolling, no payroll system quietly deducting a contribution before the money is even seen, and no default that has to be consciously refused. Every pound a self-employed person puts into a pension is there because they actively chose a provider, actively set up a contribution and actively kept paying it through years when income was uneven — the precise opposite of the mechanism that made automatic enrolment work for employees. This is the same root cause behind the self-employed protection gap covered here previously: no employer, no default, nothing happening quietly in the background. Pension saving and protection insurance are different products calling for different conversations, but they share one client population and one explanation for why that population is exposed.
Why this sits closer to the accountant than to almost anyone else
An insurer, a platform or a financial planner can infer that a self-employed person is under-protected from patterns in the data. An accountant does not need to infer anything about pension saving — it is a literal line on a document they prepare or review every year. For a sole trader, personal pension contributions are claimed as tax relief directly on the Self Assessment return. For a client who has incorporated, employer pension contributions are a deductible expense that runs through the company accounts. Either way, the absence of a pension contribution is not a signal buried in turnover volatility; it is a box that has simply never been filled in, on a form the accountant has already seen a dozen times for a longstanding client. Few other professionals have a comparably direct, dated, unambiguous view of whether this specific gap applies to a specific person.
Automatic enrolment changed the default to ensure millions more employees save for retirement. But millions of people who work for themselves have never benefited from that same principle.
What a genuinely joined-up conversation looks like off the back of this
Noticing that a client's filing history has never included a pension contribution is not advice, and it should not be treated as an invitation to become one. It is the same kind of factual observation an accountant already makes about an approaching VAT threshold or a payment on account — made at a point the accountant already has the client's attention, typically the year-end meeting where profit, drawings and next year's tax position are already on the table. Where a client wants to take that further, the shape of a genuinely joined-up conversation is consistent across the industry, not tied to any one firm: the accountant flags what the numbers show — years of trading with no pension contribution on record — and a regulated adviser takes it from there, weighing what the client can actually afford to divert from drawings without damaging cash flow, whether a personal pension, a change to how the business trades, or some combination makes sense given their age and income pattern, and how that sits against other calls on the same money. The accountant's part of that exchange starts and ends with the observation; the suitability judgement, the product selection and the ongoing advice sit entirely with the adviser.
Putting figures on it
The following is illustrative — a composite built to show how the arithmetic works, not a real client and not a prediction about any particular person's circumstances. Picture a self-employed plumber, sole trader, trading for fourteen years, turnover £61,000, taxable profit after allowable expenses around £44,000. He is 43. His Self Assessment return has never once included a pension contribution — not because he decided against saving, but because nobody attached to his business ever asked the question in a way that made him stop and answer it.
On his current trajectory, his only retirement income is the state pension: the full new State Pension pays £241.30 a week, or £12,548 a year, for the 2026/27 tax year following April's triple-lock uprating (DWP), and that is only payable in full with a complete 35-year National Insurance record. £12,548 is roughly 28% of his current taxable profit. Every year that passes without a pension contribution is not a neutral year — it is a year in which the state pension's share of his eventual income grows relatively larger, because nothing else is being built alongside it, and a year of tax relief on any contribution he might have made is gone permanently rather than deferred. A regulated adviser looking at the same file would ask different questions again: what he can realistically afford to divert from drawings without damaging cash flow, whether a personal pension or a change to how he structures the business suits someone his age better, and what fourteen years of unclaimed relief is actually worth working back from today. Those are affordability and suitability questions, not accountancy ones — but the Self Assessment history is what makes the need to ask them visible in the first place.
Two actions this week
1. Check the box, not just the total. When preparing or reviewing a Self Assessment return for a self-employed client, look specifically at whether a pension contribution has ever been claimed. If a longstanding client has never once claimed pension relief, say so as an observation at the next meeting rather than letting the return simply be filed and moved past.
2. Pull a list from records already held. Identify clients who have been trading as self-employed for five years or more with no pension contribution anywhere in their filing history. That is precisely the population the SPP's paper describes, and it is detectable from data the firm already holds, without asking the client a single question first.
What is still uncertain
The SPP's paper is a set of proposals to policymakers, not a policy decision, and it says so itself. None of the six mechanisms it sets out — a tax-system default, behavioural prompts, bank- or platform-led autosave, expanded master trusts, a state-backed scheme, or collective defined contribution arrangements — has government backing at this stage. The Pensions Commission, whose interim report supplies the paper's central statistic, is not due to publish its final report and formal recommendations to government until spring 2027, so there is no near-term date by which any of this becomes a requirement for self-employed clients. What has changed this week is the strength of the evidence behind the case for doing something, not the law itself — which is exactly why the low-risk, no-permissions step available to accountants now is simply asking the question, not waiting for legislation to ask it for them.
Common questions
What exactly did the SPP's paper find, and how solid is the 4% figure?
The Society of Pension Professionals' paper, The Missing Millions: Rethinking Pension Policy for the Self-employed, published 22 September 2026, draws its headline statistic from the Pensions Commission's own interim report, Pensions 2050: Evidence and Future Priorities, published 19 May 2026: only 4% of the UK's wholly self-employed are currently saving into a pension. That figure comes from a body government reconvened specifically to establish the scale of the UK's retirement saving shortfall, not from a product provider's marketing survey, which is why the SPP is treating it as the evidence base for its recommendations rather than restating an existing complaint. The paper itself does not attempt to re-measure the gap; it takes the Commission's figure as settled and asks what policy response follows from it.
Why are the self-employed excluded from automatic enrolment in the first place?
Automatic enrolment works through the employer: a business is legally required to enrol eligible staff into a workplace pension and contribute alongside them, and the employee has to actively opt out if they do not want to participate. That entire mechanism depends on there being an employer to do the enrolling. A sole trader, a contractor or a freelancer has no employer relationship with themselves, so there is no legal trigger, no default scheme and no one running payroll deductions in the background. Saving only happens if the self-employed person actively chooses a pension product, actively sets up the contribution and actively keeps it going through years when income fluctuates — which is precisely the opposite of how automatic enrolment succeeded for employees.
Does this mean the government is about to force self-employed people into a pension?
No, and the SPP's paper is explicit that it is a set of options for policymakers, not a policy announcement. Its recommendations range from a tax-system default and behavioural prompts through to more structural ideas like extending defined contribution master trusts, a state-backed scheme, or collective defined contribution arrangements — none of which are government commitments at this stage. The Pensions Commission itself is not due to publish its final report, with formal recommendations to government, until spring 2027. Anything that reaches self-employed clients as a concrete requirement is therefore some way off, and will go through consultation before it does. What has changed now is the strength of the evidence behind the case for doing something, not the law.
Is this the same issue as the self-employed protection gap covered here recently?
Related, but distinct — see the self-employed protection gap for the insurance side of this picture. That piece covered the FCA's finding that self-employed and gig-economy clients are disproportionately likely to hold no life insurance, critical illness cover or income protection. This is about pension saving specifically: money put aside for retirement, not cover against illness or death. Both gaps share the same root cause — no employer quietly defaulting anything on the self-employed person's behalf — but they call for different conversations and different products, and a client can easily have one gap without the other. Treating them as a single issue risks a firm raising only the more memorable of the two and missing the other entirely.
What should a firm actually do differently this week?
Two things, both achievable from records the firm already holds. First, when preparing or reviewing a Self Assessment return for a self-employed client, note whether a pension contribution has ever appeared on it, and if a longstanding client has never claimed pension relief, say so as an observation at the next meeting rather than letting the return simply be filed. Second, build a short list of clients who have been trading as self-employed for five years or more with no pension contribution on record — that is precisely the population the SPP's paper is describing, and it is identifiable from filing history alone, without asking the client anything first. For the broader case on why accountants are well placed to raise this at all, see what joined-up advice actually looks like.
Roughly 9% of UK adults have paid for financial advice in the past two years, and the adviser market has consolidated around a shrinking number of specialist firms — sub-5,000 IFA firms nationally, with an average new client portfolio around £411,000 (The lang cat, State of Advice Report 2025). The self-employed, with irregular income and no employer prompting them toward advice, were never likely to be in that market's sights on their own initiative. The SPP's paper does not change that structural gap. What it does is put an official, dated figure behind a group accountants already have on file, and hand the profession a specific, low-risk reason to check one box at the next Self Assessment filing.
