- Your company can pay into your pension and deduct it from corporation tax.
- There's no National Insurance on an employer pension contribution.
- The money must hit the pension before your accounting year end to count.
Pension contributions from a limited company are one of the few genuinely tax-efficient moves most directors never make, and a good limited company accountant will raise it before you do. Your company pays into your pension as an employer, the contribution comes off its corporation tax bill, and unlike money you pay in yourself it isn’t capped by your salary.
That makes it a different tool from salary or dividends. It’s also the one part of profit extraction where the money leaves the company as a deductible cost rather than as taxed income.
This guide covers the amount, the mechanism, and the point at which a pension beats a dividend. It doesn’t cover which fund to pick. That’s a decision for a regulated financial adviser, and we’ll be clear later about where our advice stops.
Not sure how much your company can put in?
Can my limited company pay into my pension?
Yes. A UK limited company can pay into a director’s pension as an employer contribution, in the same way it would contribute for any other employee. The company writes the payment to a registered pension scheme, and for tax purposes it’s treated as part of the cost of employing you.
This is worth saying plainly because a lot of directors assume pensions are something they fund from their own post-tax money. They can, but the employer route is usually the one that matters, and the rest of this guide explains why.
There’s a related point to clear up early. This isn’t about auto-enrolment. Auto-enrolment is the duty you have towards your staff, and a sole director with no other employees normally sits outside it. Paying into your own pension through the company is a separate, voluntary decision, covered in how to pay yourself from a limited company as one leg of the wider extraction question.
Employer or personal: which contribution actually helps a director?
There are two ways money reaches your pension, and for a company director they’re taxed very differently.
A personal contribution comes out of money you’ve already drawn, usually salary or dividends. You get tax relief on it, but there’s a catch that bites directors hard: you can only get relief on personal contributions up to 100% of your relevant UK earnings in the year. Dividends don’t count as earnings for this test. So a director on a small £12,570 salary topped up with dividends can personally contribute far less than they might expect.
An employer pension contribution sidesteps that entirely. The company makes it, so it isn’t limited by your salary at all. It’s capped instead by your annual allowance, which we come to next. For most owner-managed companies, the employer route lets you put in far more, and it does so before the money is ever taxed as your income.
That’s the whole reason director pension contributions are usually structured as employer contributions. The comparison against taking money out of your company tax-efficiently turns almost entirely on this point.
How much can the company put in?
The ceiling is your annual allowance. For the 2026/27 tax year it’s £60,000, and it counts everything paid into your pensions that year, employer contributions, your own contributions, and anything a third party pays in. Verified against GOV.UK, September 2026.
Three things stretch or shrink that £60,000:
- Carry-forward. If you didn’t use your full allowance in the previous three tax years, and you were a member of a pension scheme during them, you can carry the unused amount forward. In the right circumstances that allows a single-year contribution well above £60,000.
- The tapered annual allowance. If your adjusted income goes over £260,000 (and your threshold income over £200,000), the £60,000 starts reducing by £1 for every £2 of adjusted income above £260,000, down to a floor of £10,000 once adjusted income reaches £360,000. Most owner-managed directors never touch this, but high earners need to check it.
- The money purchase annual allowance. If you’ve already started flexibly drawing from a defined contribution pension, your allowance for new contributions usually drops to £10,000.
One more limit sits behind the employer route. A contribution has to pass HMRC’s “wholly and exclusively” test to be deductible, which in practice means it should be reasonable for the work you do. We explain what that means for the tax relief in the next section.
Wondering how much carry-forward you’ve actually got?
How does the corporation tax relief actually work?
An employer pension contribution is a business expense. When the company pays it, the amount comes off the company’s profit before corporation tax is calculated, so the company pays tax on a smaller profit figure. That’s the relief.
How much it saves depends on the corporation tax rate that applies to the company’s profits for 2026/27:
- 19% on profits up to £50,000 (the small profits rate).
- 25% on profits above £250,000 (the main rate).
- An effective rate between the two on profits from £50,001 to £250,000, through marginal relief. In that band each extra pound of profit is actually taxed at 26.5%, which is the figure that makes pension contributions so effective for a company sitting there.
So a company in the marginal band saves 26.5p of corporation tax for every £1 it puts into the director’s pension. All these rates are verified against GOV.UK, September 2026.
There’s a condition attached, the “wholly and exclusively” one from the last section. HMRC’s own guidance says pension contributions will normally pass it, and that it’s “relatively rare” for one to fail. For a controlling director the test is whether the contribution is in line with what you’d pay an unconnected employee doing a similar job. A modest salary paired with a large pension contribution can still be fine, but the total package needs to make commercial sense. This is one of the judgement calls where an accountant earns their fee. It also sits alongside the wider work of reducing your corporation tax bill.
There’s also no National Insurance on an employer pension contribution. Compare that with salary, where the company pays employer National Insurance at 15% on earnings above £5,000 a year. Every pound routed to a pension instead of salary saves that 15% as well as the income tax and employee NI on the way out.
Pension, salary or dividend: what does the same profit look like three ways out?
Here’s the point of the whole article, in one worked example. Take a single-director company sitting in the marginal relief band, with a director already on the standard £12,570 salary and paying higher-rate tax on anything more. The company wants to get £20,000 of profit across to the director. Figures are illustrative and rounded.
| Route out | Corporation tax effect | Personal tax and NI now | Result |
|---|---|---|---|
| Employer pension contribution | Deductible: saves £5,300 CT (26.5%) | None | £20,000 in the pension, locked until pension access age |
| Dividend | Not deductible: £5,300 CT paid first | £4,960 dividend tax (33.75%) | About £9,740 in hand now |
| Salary / bonus | Deductible, but triggers £2,610 employer NI | £6,960 income tax plus £350 employee NI | About £10,090 in hand now |
The same £20,000 of profit lands as a full £20,000 inside the pension, or as roughly £9,700 to £10,100 in the director’s pocket through the other two routes. The pension route wins on tax by a wide margin, because it’s the only one of the three that avoids both the corporation tax hit and the personal tax on extraction.
The catch is liquidity, and it’s a real one. The pension money is locked away until pension access age, currently 55 and rising to 57 from 2028. Salary and dividends are spendable today. The right answer is rarely all pension: it’s a mix that funds your life now and uses the pension for the profit you genuinely don’t need this year. The full salary-versus-dividend maths lives in our guide to paying yourself salary, dividends or both; this table just adds the third door.
Why does the money have to leave the company before your year end?
Timing is the trap most directors fall into. An employer pension contribution is only deductible in the accounting period in which it’s actually paid. Not accrued, not promised, not decided in a board minute. Paid, and sitting in the pension scheme’s account, before your company’s year end.
That’s why this is a year-end job. If your accounting period ends on 31 March and you want the contribution to reduce that year’s corporation tax bill, the money needs to be with the pension provider by 31 March, with a few days’ banking buffer on top.
There’s a second timing point for large one-off contributions. HMRC can require tax relief on a very large contribution to be spread across more than one accounting period rather than taken all at once. It only tends to affect contributions that are big relative to the previous year’s, but it’s another reason to plan a large payment rather than fire it off in the last week of the year.
What does a company pension contribution do to your self assessment?
For an ordinary employer contribution within your annual allowance, the answer is refreshingly little. Because the company made the payment, not you, there’s no personal tax relief to claim on your own return for it. It doesn’t reduce your personal tax bill, because it never passed through your personal income in the first place.
It only reaches your self assessment if you go over your available annual allowance. In that case you report the excess in the pension savings section of your return and pay an annual allowance charge at your marginal rate, which claws back the relief on the amount over the line. That’s the scenario carry-forward is designed to avoid.
If you also make personal contributions on top of the company’s, those follow the normal personal-relief rules and can interact with your return. It’s worth keeping the two streams clearly separated, which your accountant will do as part of preparing your director’s tax return.
Where does auto-enrolment fit, and why is a sole director usually outside it?
Auto-enrolment and director pension contributions get confused constantly, so it’s worth drawing the line cleanly. Auto-enrolment is a legal duty employers have to enrol eligible staff into a workplace pension and contribute to it. A company whose only worker is a single director, with no employment contract, generally has no auto-enrolment duties at all.
Making an employer contribution into your own pension doesn’t create one either. You’re choosing to contribute, not being obliged to. The two live in different parts of the rulebook.
If you do have staff, the employer duties are a separate obligation that runs alongside your own contributions, and we cover them in workplace pension auto-enrolment duties. For a solo business owner, though, the pension conversation is purely about the extraction decision, not about compliance.
What can Sleek advise on, and what needs a financial adviser?
This is the honest bit, and it matters. Sleek handles the company side of a pension contribution: whether it’s deductible, how it interacts with your corporation tax and your salary and dividend planning, and the payroll and filing mechanics of getting it paid correctly. That work is done by a qualified accountant, with our AI handling the routine calculations and a human checking every figure before it reaches you, so you can see how each number was reached.
What we don’t do is investment advice. Which pension provider to use, which fund to hold, whether a SIPP suits you, and whether locking money away until pension access age fits your wider retirement plan, those are decisions for a regulated financial adviser, and we’ll say so rather than stray into territory we’re not authorised for.
The split in practice is simple. We tell you what the company can contribute and what it saves. A financial adviser tells you where that money should go once it’s in the pension. Sleek’s accounting service covers the first half of that, and you’ll find the wider set of director guides in our UK resources hub.

FAQs on pension contributions limited company
Can I pay more into my pension than I earn in salary from the company?
Through an employer contribution, yes. The 100%-of-earnings cap only applies to contributions you make personally. Because the company makes an employer contribution, it isn’t limited by your salary at all, only by your annual allowance, which is £60,000 for 2026/27 before any carry-forward.
Is there any National Insurance on an employer pension contribution?
No. Employer pension contributions are free of National Insurance, for both the company and you. That’s a direct saving against salary, where the company pays 15% employer NI on earnings above £5,000 a year and you pay employee NI on your side.
Do I need a payroll scheme to make company pension contributions?
Not necessarily. An employer pension contribution can be paid straight from the company to a registered pension scheme without running it through payroll, since it isn’t salary. You’ll still want it recorded properly in the company accounts as an employer contribution so the corporation tax deduction is clean.
Can my company pay into my spouse's pension if they work for the business?
It can, provided your spouse genuinely works for the company and the contribution is reasonable for the role they do. The same “wholly and exclusively” test applies: a large contribution for a spouse doing little real work is the kind of case HMRC can challenge. Paid for genuine work at a sensible level, it’s an allowable employer contribution like any other.
What happens if I exceed the annual allowance?
You report the excess on the pension savings section of your self assessment and pay an annual allowance charge at your marginal rate of income tax, which removes the tax advantage on the amount over the limit. Before that happens, carry-forward of unused allowance from the previous three years often absorbs the excess, so it’s worth checking that first.
Can my company make a pension contribution for a previous year?
An employer contribution is deductible in the accounting period it’s actually paid, so the company can’t retrospectively deduct one in a year that’s already closed. Carry-forward is a separate thing: it lets you use up unused annual allowance from earlier years to support a larger contribution paid now, not to backdate the payment itself.
Does a pension contribution reduce my corporation tax bill pound for pound?
No, it reduces it by the corporation tax rate on the contribution, not the full amount. A company in the marginal band saves 26.5p per £1, a small-profits company saves 19p, and a main-rate company saves 25p. The rest of the contribution is still money that’s genuinely left the company for your pension rather than tax it would otherwise have paid.
