Self-employed people cannot use salary sacrifice and must use personal pensions or SIPPs. Relief at source gives 20% automatically; higher-rate relief requires a Self Assessment claim. Here is how it works.
Most self-employed people use personal pensions or SIPPs that operate under relief at source (RaS). When you make a contribution, you pay the net amount and your pension provider automatically claims 20% basic-rate relief from HMRC, adding it to your pension pot. This means every £80 you contribute becomes £100 in the pension. The relief is received whether or not you actually pay 20% income tax, though HMRC has the right to reclaim relief if your income is below the personal allowance.
The annual allowance for self-employed people is the same as for employees: £60,000 or 100% of net relevant earnings, whichever is lower. Net relevant earnings for the self-employed means trading income, property income and certain other sources, not dividends, which do not qualify as relevant earnings. This means a company director drawing only dividends cannot make personal pension contributions that attract tax relief, though the company can make employer contributions.
If you pay 40% or 45% income tax, you are entitled to more than the 20% basic-rate relief that is automatically applied under RaS. To claim the additional relief, you must file a Self Assessment tax return and enter your gross pension contributions (the amount in the pension, including the provider's 20% top-up) in the relevant section. HMRC will either reduce your tax liability or, if you have already paid, issue a repayment.
For a self-employed higher-rate taxpayer contributing £16,000 net per year: the provider tops up to £20,000 gross. Via Self Assessment, they claim 40% − 20% = 20% additional relief on £20,000 = £4,000. Total relief: 40% × £20,000 = £8,000. Net cost of the £20,000 pension contribution: £16,000 − £4,000 = £12,000. This is the same outcome as a higher-rate employed taxpayer using net pay arrangement, but it requires an annual Self Assessment filing.
Scottish self-employed taxpayers face the same complication as Scottish employed workers on relief at source: the provider claims 20% regardless, but Scottish rates may differ. Intermediate-rate (21%) Scottish taxpayers claim an extra 1% via Self Assessment. Higher-rate (42%) taxpayers claim the extra 22%. Top-rate (45%) taxpayers claim the extra 25%. All of these claims are made through the same Self Assessment process, with the gross pension contribution entered on the SA100.
Owner-managed limited company directors have a particularly powerful tool: employer pension contributions paid directly from the company. These are not limited by the director's personal salary (unlike personal RaS contributions which need relevant earnings) as long as HMRC regards them as being wholly and exclusively for the purposes of the trade. The contributions reduce the company's taxable profits, saving corporation tax at 19–25%.
The director also avoids the dividend income tax and National Insurance that would apply if the same money were extracted as additional pay. Combined with carry-forward allowance from prior years, a profitable director can extract very substantial sums from the company in a tax-efficient way. Always take professional advice on the wholly-and-exclusively test and the interaction with the annual allowance.
No. Salary sacrifice is only available to employed workers, as it requires an employer to amend the employment contract and make pension contributions in place of salary. Sole traders, partners and owner-managed company directors drawing only dividends cannot use salary sacrifice. A director who draws a salary from their company could theoretically use salary sacrifice, but this requires the company to operate the scheme.
A Self-Invested Personal Pension (SIPP) gives maximum flexibility and investment choice. Stakeholder pensions are a low-cost alternative with capped charges. Both operate under relief at source. The 'best' pension depends on investment preferences, cost sensitivity and whether you want the ability to hold commercial property or other alternative assets.
Yes, and this is often very tax-efficient. A limited company can make employer pension contributions directly to a director's pension. These contributions are a deductible business expense, reducing corporation tax. They also avoid income tax and National Insurance that would apply if the money were paid as salary or dividend. This is one of the most tax-efficient routes out of a limited company for owner-directors.
