Introduction
For business owners and directors, pension contributions can be a smart financial strategy for both retirement planning and tax efficiency. But are they fully tax-deductible for your business?
Under S34 Income Tax (Trading and Other Income) Act 2005 and S54 Corporation Tax Act 2009, pension contributions made by a company for its directors or employees can be deducted as a business expense, but only if they are made wholly and exclusively for the purposes of trade.
However, HMRC may disallow the deduction if they determine that the pension contributions have a non-trade purpose or are excessive. This guide will help ensure your pension contributions remain fully tax-deductible.

When Are Pension Contributions Tax-Deductible?
To be eligible as a tax-deductible business expense, pension contributions must:
✔️ Be part of a structured remuneration package.
✔️ Be reasonable in proportion to the director’s salary and role.
✔️ Be comparable to contributions for employees in similar positions.
✔️ Have a clear business purpose rather than serving as a tax avoidance strategy.

When Might HMRC Disallow Pension Contributions?
HMRC may challenge and disallow pension contributions if they believe they are made for non-business reasons, including:
❌ Excessive remuneration – Contributions are disproportionately high relative to salary or work performed.
❌ Artificial tax planning – Contributions structured primarily to reduce tax rather than to provide fair compensation.
❌ Unexplained increases – Sudden spikes in pension contributions without justification.

Key Case Law: Samuel Dracup & Sons Ltd v Dakin (1957) 37TC377
This case confirmed that if a payment is made for non-business reasons, it cannot be deducted for tax purposes. HMRC applies this principle when assessing whether pension contributions are wholly and exclusively for trade.

How Does HMRC Assess Pension Contributions?
When reviewing pension contributions, HMRC considers:
📊 Comparison with other employees – Contributions should align with industry standards.
📈 Historical consistency – A sudden increase in pension contributions may trigger scrutiny.
📋 Overall remuneration package – The pension should be reasonable compared to salary and job role.
📌 Underfunded schemes – If the company increases contributions to fix underfunding, HMRC will assess the justification.

How to Ensure Your Pension Contributions Are Deductible
✅ Include pension contributions in a structured remuneration package.
✅ Maintain proper documentation justifying salary and pension levels.
✅ Ensure contributions are proportionate to salary and duties.
✅ Avoid excessive contributions that deviate from standard market rates.
💡 If HMRC finds that part of a pension contribution is not wholly for trade, only that portion will be disallowed.
