Most limited company directors know the basic playbook: pay yourself a small salary up to the personal allowance, top up with dividends, keep National Insurance down. It’s sound advice as far as it goes. But it usually stops one step too early — because it treats the pension as something you fund personally, out of post-tax dividends, when there’s a route that’s often meaningfully more efficient: having the company pay into your pension directly.
This isn’t personal financial or tax advice — it’s an explanation of how the mechanism works, so you can weigh it up with your accountant. For anything beyond a modest contribution, that conversation is worth having before you act.
Two very different routes into the same pension
Personal contributions come from money you’ve already been paid — salary or dividends you’ve received, after any tax due on them, which you then choose to put into a SIPP. HMRC tops up basic-rate relief automatically, and higher or additional-rate taxpayers can claim more back through Self Assessment. But personal contributions are capped by your relevant UK earnings — broadly, your salary. If you’re a director taking a low salary and topping up with dividends, that cap can be very restrictive, since dividends don’t count as relevant earnings for this purpose.
Employer (company) contributions work completely differently. The company pays into your pension directly, before any of that money has been paid to you as salary or dividends at all. Because of that, three things change at once:
- The salary restriction doesn’t apply. Employer contributions aren’t capped by your relevant earnings — you can take a modest £12,570 salary and still have your company contribute up to the full annual allowance.
- No National Insurance is due, on either side — not employee NI, not employer NI. Compare that to paying the same amount out as salary, where employer NI alone would take a real bite before the money even reached you.
- The contribution is normally a deductible business expense, reducing the company’s taxable profit and therefore its Corporation Tax bill — provided it meets HMRC’s “wholly and exclusively for the purposes of the business” test. In practice, this is well-established and routinely accepted for owner-managed companies, though very large or unusual contributions relative to the work done can attract scrutiny.
Why the numbers stack up
Corporation Tax for 2026/27 runs at 19% on profits up to £50,000, 25% on profits above £250,000, and an effective marginal rate of around 26.5% on profits that fall in the band between those two figures. A pension contribution that reduces profits sitting in that marginal band is doing more tax-saving work per pound than one that only nudges profits down from, say, £280,000 to £260,000.
Put concretely: a company with profits comfortably inside that £50,000–£250,000 band making a substantial employer pension contribution isn’t just avoiding NI on the money — it’s also cutting Corporation Tax at closer to 26.5p in the pound than the headline 19% or 25% rates might suggest.
The annual allowance — and the one most owner-directors don’t know about
The standard annual allowance for 2026/27 is £60,000, covering all pension contributions from any source combined — personal, employer, and the tax relief added on top. Employer contributions count fully toward this limit, just as personal ones do.
What’s less well known: unused allowance can be carried forward from the three previous tax years, provided you were a member of a registered pension scheme in those years. For a director who hasn’t been contributing — perhaps because the business only recently became profitable, or pension planning simply hasn’t been a priority — this can allow a single-year contribution well above £60,000, potentially up to £240,000 if none of the three prior years’ allowances have been used, assuming company profits can support it.
Timing matters
To claim the Corporation Tax deduction in a given accounting period, the contribution generally needs to be paid before the company’s year-end. A contribution made after year-end falls into the following period’s accounts instead. This is why many directors treat pension contributions as part of a deliberate pre-year-end review, alongside dividend and salary planning, rather than something done on an ad hoc basis through the year.
Where this fits into the bigger picture
This isn’t an argument for maximising pension contributions over everything else — accessibility matters, and money in a pension is generally locked away until at least 55, rising to 57 from 2028. It’s one lever among several (salary, dividends, pension, retained profit) and the right mix depends on your income needs now versus later, how close you are to retirement, and what else the company needs its cash for.
But for directors who’ve been defaulting to “salary plus dividends, pension later” without ever running the employer-contribution numbers, it’s often the single most overlooked piece of the picture — and one genuinely worth an hour with an accountant to model properly for your own figures.
This calculation looks somewhat different if you trade as a sole trader rather than through a limited company, since the employer contribution route covered here doesn’t exist in the same form outside a company structure.
