How much to pay into a pension when you are self-employed is your call: no figure is set for you, but UK limits cap what earns tax relief each year.
People who work for themselves often ask how much pension they should be paying in, and the honest answer is that it depends on profits that rise and fall, other savings and the retirement they have in mind. This page cannot choose a figure for you. It sets out the limits that frame the decision, how the tax relief arrives, what a lumpy income does to the picture, and what the State Pension adds. Would you rather have your own figures gone through by someone? Describe your profits in this page's enquiry form, and a caller from an FCA-authorised adviser firm will be in touch without any charge.
Nobody sets your figure, which is why the reference points matter
An employee who is automatically enrolled has a floor chosen for them. GOV.UK's table for workplace schemes shows the total minimum as 8% of qualifying earnings, with the employer paying at least 3% and the employee 5%, on earnings between £6,240 and £50,270 a year. That is a legal floor for employer schemes, not advice and not a target for a sole trader; how auto-enrolment works explains who it covers.
A sole trader pays a personal pension or SIPP directly, so the useful questions come in a different order: the ceilings on tax relief, then how income behaves across a year, then what the State Pension already provides. A forecast or calculator turns that into a number more usefully than a rule of thumb; see pension calculators compared and getting a pension forecast. Which provider or product to use is a separate question, covered in pensions for the self-employed.
The limits, side by side
Four figures do most of the capping. They are the 2026/27 UK tax year positions from GOV.UK and HMRC; none is a target, and none is a calculation of your tax.
| Limit | Figure | What it caps |
|---|---|---|
| Earnings limit | 100% of your relevant UK earnings, or the £3,600 "basic amount" if higher | What attracts tax relief on your own payments |
| Annual allowance | £60,000 | Total paid in by you and anyone else across all your pensions before a tax charge arises |
| Tapered allowance | Where threshold income is over £200,000, falls by £1 for every £2 of adjusted income over £260,000, to a floor of £10,000 | The annual allowance, for very high earners |
| Money purchase annual allowance | £10,000 (2023-24 onwards) | Money-purchase savings, once you have flexibly taken money from a pension |
For a sole trader, relevant UK earnings means taxable trading profits, not turnover, and the annual allowance counts payments by anyone, so a company paying in on your behalf uses it too. What counts as earnings, and what happens if profits are below £3,600, is set out in pensions for the self-employed; the allowances in the annual allowance guide, the taper and the money purchase annual allowance.
How the relief reaches you
GOV.UK says all personal and stakeholder pensions use relief at source: you pay in from taxed income and the provider claims 20% from the government and adds it. Our working, dated 20 October 2026: a personal payment of £8,000 divided by 0.80 gives £10,000 in the pension, £2,000 of it added by the provider. It is the £10,000 gross figure that is tested against the earnings limit and the annual allowance.
Relief above 20% is not added for you; higher and additional rate taxpayers claim it on their Self Assessment return, and Scotland has its own bands (see the pension tax relief guide and tax relief for the self-employed). In a year with no Income Tax to pay, the provider can still claim 20% on contributions up to 80% of earnings, or £2,880 with no earnings; by the same working, £9,000 of earnings allows £7,200 paid in, which becomes £9,000 gross, and £3,600 multiplied by 0.80 is £2,880. Whether a higher-rate claim applies turns on which band your profits reach. An FCA-authorised adviser can go over that band by band, and the form on this page books that call at no cost to you.
Uneven income and one-off payments
Profits that swing from year to year are the usual reason a fixed monthly figure feels wrong. The rules leave room for this. HMRC's Pensions Tax Manual lets contributions be made weekly, monthly, annually or "at any other agreed time interval", so a lump sum after a strong quarter is as valid as a standing order. What matters is the tax year it falls in.
- Relief follows the year of payment. Relief belongs to the tax year in which the payment is actually made, so a payment made just before 6 April and one made just after belong to different years, with different earnings and different limits.
- The earnings test uses that year's profits. A weak year lowers the limit for that year, and unused relief cannot be carried back or forward, so a low-profit year cannot borrow from a high one.
- The annual allowance behaves differently. Unused allowance from the previous three tax years might be carried over, subject to conditions in the carry forward guide; this lifts the allowance, not the earnings limit.
Money paid in is generally tied up until the scheme's access age, which for most personal pensions is "not normally before 55". The normal minimum pension age in the Finance Act 2004 rises to 57 on 6 April 2028, except in uniformed services schemes and for members with a protected pension age; the pension age guide has the detail. Tax is charged when money comes out, and the value of investments can fall as well as rise, so a pension may return less than was paid in. How that sits against a business that sometimes needs cash is part of what some people take to an adviser rather than settle alone.
National Insurance and the State Pension underneath
The State Pension is built from National Insurance, not from private pension payments, and for the self-employed the route changed in 2024-25. GOV.UK's self-employed rates page, as archived in February 2024, said that with profits of £12,570 or more "you usually pay Class 2 and Class 4 National Insurance rates". From 2024 to 2025 (archived January 2025), Class 2 was no longer payable: with profits of £6,725 or more, "Class 2 contributions are treated as having been paid to protect your National Insurance record", and below that it was voluntary at £3.45 a week. For 2026 to 2027 the same rule applies with the threshold at £7,105. Class 4 is still due on profits over £12,570, at 6% up to £50,270 and 2% above that.
Below £7,105 you pay nothing but "can choose to pay voluntary Class 2 contributions", at £3.65 a week for 2026 to 2027, to fill gaps, going back up to 6 years. The new State Pension needs 10 qualifying years to pay anything and, for a record starting after April 2016, 35 for the full rate of £241.30 a week in 2026 to 2027. A qualifying year can come from paid contributions, credits or voluntary payments. More is in the State Pension guide and its self-employed companion.
Benchmarks, and how to read them
Rules of thumb for self-employed saving circulate widely, usually as a percentage of profits or of age. This page does not adopt one: a percentage with no source for the person's income, other pots and aims is a guess, and pension contributions by age looks at the age-based ones. Two published reference points can be traced to their publisher.
The first is the 8% workplace minimum above, an employee's floor. The second is Pensions UK, formerly the PLSA, whose Retirement Living Standards were updated in 2026. For one person it prices a year at £13,900 (minimum), £32,700 (moderate) and £45,400 (comfortable), with higher figures for London, and for a couple £22,500, £45,400 and £62,700. Pensions UK is clear that these are the costs of a living standard, not the income you will need: they are after-tax spending, leave out rent and mortgage payments, and so the income required may be higher. Set beside them, the full new State Pension leaves more of any chosen standard to come from elsewhere. How big a pot that implies is the subject of how much pension you need, and whether the State Pension is enough covers the floor.
Working back from a living standard to an income, a pot and finally a contribution is where the limits above come in, along with uneven profits, other savings and a partner's pension. An adviser can look at all of that in one conversation.
Questions self-employed savers ask
Is there a minimum I have to pay in?
The 3%, 5% and 8% figures are GOV.UK's minimums for a workplace scheme you are automatically enrolled into. A personal pension provider will set its own minimum payment, so ask before opening one.
Can I pay in more than I earn?
Relief is capped at 100% of relevant UK earnings, or the £3,600 basic amount where that is higher, and GOV.UK says HMRC can ask for relief on anything over the limit to be repaid. The annual allowance is a separate cap on the year's total.
Do I still get a State Pension if I pay no Class 2?
With profits at or above £7,105 in 2026 to 2027, Class 2 is treated as paid for your record. Below that, voluntary Class 2 is an option, and the State Pension forecast shows whether it would help. See the State Pension guide.
What if I have already taken money from a pension?
Flexible access, such as cash from flexi-access drawdown or an uncrystallised funds pension lump sum, can bring in the £10,000 money purchase annual allowance for later years. Check with your provider before paying in again; the money purchase annual allowance guide has the triggers.
