Pension contributions are one of the most tax-efficient ways for contractors to extract money from their limited company. Unlike salary or dividends, employer pension contributions are not subject to income tax or National Insurance, and they reduce your Corporation Tax bill. Despite this, many contractors neglect pension planning, focusing instead on maximising their short-term take-home pay.
Employer contributions
Your limited company can make employer pension contributions directly into a personal pension scheme such as a SIPP (Self-Invested Personal Pension). These contributions are treated as a business expense, reducing your company's Corporation Tax liability. They are not taxed as a benefit in kind on you personally, and they do not count towards your income for income tax purposes.
Annual limits
The annual allowance for pension contributions is currently £60,000 (2025/26 tax year). This includes all pension contributions from all sources. If you have unused allowance from the previous three tax years, you can carry it forward. This means a contractor who has made no pension contributions for several years could potentially contribute up to £180,000 in a single year, though the contributions must be supported by the company's profits.
Practical strategy
Most contractor accountants recommend a balanced approach. Rather than trying to minimise your tax bill to zero through maximum pension contributions, consider what proportion of your income you genuinely want locked away until age 57 (rising to 58 from 2028). A common approach is to contribute enough to bring your Corporation Tax profits below £50,000, avoiding the marginal rate, while retaining sufficient funds for dividends and working capital.
Choosing a pension provider
Low-cost SIPP providers such as Vanguard, Fidelity, and AJ Bell offer straightforward platforms where you can invest pension contributions in diversified index funds. Annual platform fees range from 0.15 percent to 0.45 percent of your portfolio value. Avoid high-fee advisers who charge percentage-based ongoing fees unless they are providing genuinely valuable bespoke advice.
