No employer means you build your own
As a sole trader you have no employer pension and no auto-enrolment safety net, so your retirement is entirely down to what you put away yourself. The good news is that pension contributions are highly tax-efficient: you can contribute up to 100% of your trading profit in a tax year and receive tax relief at your marginal rate, capped at the £60,000 annual allowance. Even with no profit you can still pay in £3,600 gross a year.
How tax relief works for sole traders
Unlike a limited company, a sole trader pays pension contributions personally from taxed income. Basic-rate relief (20%) is added automatically inside the pension, so a £100 net contribution becomes £125 in the pot. If you are a higher-rate taxpayer, you claim the extra 20% (or 25% for additional-rate) through your self-assessment tax return — money many sole traders forget to reclaim.
Choosing a provider
| Provider | Fee (2026) | Best for |
|---|---|---|
| Vanguard SIPP | 0.15% (cap £375) | Lowest-cost index investing |
| AJ Bell SIPP | 0.25% | Wider fund and share choice |
| PensionBee | 0.50–0.95% | Hands-off app-based saving |
| Nest | 1.8% on contributions + 0.3% AMC | Self-employed access, very simple |
For most sole traders who are comfortable choosing a single global index fund, a Vanguard SIPP is the cheapest and simplest option. If you would rather not think about investments at all, PensionBee or Nest manage everything for a higher fee.
Managing irregular income
- Make flexible lump-sum contributions in good months rather than committing to a high monthly amount.
- Use carry forward to sweep up to three years of unused allowance in a strong year.
- Keep paying Class 2/4 National Insurance to protect your State Pension entitlement — the full new State Pension is £11,973 a year.
- Contribute before the 5 April tax-year end to use that year's allowance and relief.
How much should a sole trader save?
Without an employer contribution to lean on, sole traders need to save a higher proportion of income than employees to reach the same retirement. A useful rule of thumb is to put away a percentage of your profit equal to half your age when you start — so beginning at 30 suggests around 15% of profit. That sounds steep, but pension tax relief softens the blow: a basic-rate taxpayer effectively pays 80p for every £1 in the pot, and a higher-rate taxpayer just 60p. Automating a regular contribution and topping up after a strong quarter is far more effective than waiting until year end and discovering the cash has been spent.
Sole trader or limited company for pensions?
As your profits grow, you may consider incorporating, partly for pension efficiency. A limited company can make employer contributions that are not limited by your salary, save corporation tax and avoid National Insurance — advantages a sole trader cannot access, since sole traders contribute personally from taxed profit. Incorporation brings extra admin and accountancy costs, so it is not automatically worthwhile, but for higher-earning sole traders wanting to make large pension contributions it can tip the balance. Discuss the trade-offs with an accountant, because the best structure depends on your overall income, profit level and long-term plans.
Verdict
The best pension for a sole trader is a low-cost SIPP, with Vanguard the clear value winner and AJ Bell close behind for those wanting more choice. If you prefer a fully managed, set-and-forget approach, PensionBee or Nest are sensible. Whatever you choose, remember to claim higher-rate relief through self-assessment and to keep your National Insurance record intact for the State Pension.
