Company pension contributions are normally deductible for corporation tax if paid wholly and exclusively for the trade, in the period they are paid.
A company that pays into a registered pension scheme for a director or employee is, in most cases, treating the payment as a business expense. That lowers its taxable profit, but only if the payment passes one test and lands in the right accounting period. Larger payments bring two further checks: spreading of the deduction, and the individual's annual allowance. If your company's set-up is unusual, an FCA-authorised adviser can weigh its pension side up with you at no cost, in a phone conversation that the form on this page books.
Do company pension contributions reduce corporation tax?
Yes, for a company that carries on a trade. HMRC's Business Income Manual says relief on an employer's contribution "is given in accordance with the normal tax rules for the deductibility of the expenses of a trade", with two departures: a contribution is not treated as a capital payment even if it otherwise would be, and the timing follows payment rather than the accounts.
In the company's tax computation, that means the pension cost shown in the profit and loss account is added back and replaced by the contributions actually paid in the period. The reduction in tax then depends on the rate the profits would otherwise have borne. For the Corporation Tax year starting in 2026 (years begin on 1 April), as in each year since 1 April 2023, HMRC's rates table gives a main rate of 25% and a small profits rate of 19%, with Marginal Relief for profits between £50,000 and £250,000. The thresholds are scaled down for short accounting periods and for associated companies.
That is the sense in which employer contributions are "pre-tax" for the company. How the employee is treated is a separate question, answered on the employer contributions page.
Which company pension payments can HMRC challenge?
Fewer than people expect. The manual says it will be "relatively rare in the context of pension contributions to have to consider whether there is a non-trade purpose for the employer's decision to make the contribution", and that as part of the cost of employing staff, pension contributions are likely to be allowable. The question is one of fact in each case.
For an owner-managed company, HMRC's yardstick is whether the director's whole pay package, not the pension payment alone, is comparable with what unconnected staff doing work of similar value receive; where only a definite part fails, only that part is disallowed. HMRC's own staff are told to get specialist advice before challenging a deduction on this ground.
How that test applies to a sole director, with the manual's own wording, is set out on paying in through a limited company; choosing a director's pension covers which scheme to pay into.
When does the company get the deduction: paid or accrued?
When the money is paid. The manual's wording is that relief "is given for the accounting period in which it is paid and not in the period(s) it is recognised in the accounts". The Pensions Tax Manual adds that relief can only be given on contributions that have actually been paid, so a provision or an accrual in the accounts earns no deduction by itself. This matters most for defined benefit schemes, where the charge in the accounts can differ widely from the cash paid in.
The deduction is also tied to one period. For a trade, contributions can only be deducted for the period of account in which they were paid, and the manual says it is not possible to carry a contribution back or forward to other periods; the departures the Business Income Manual describes are the spreading rules below and a deficiency payment made after the trade has ceased. A company paying shortly before its year-end and another paying shortly after can therefore see the relief fall a full year apart.
The company's year and the individual's tax year are different clocks. The deduction follows the company's period of account; the annual allowance runs from 6 April to 5 April, as the last section explains.
When is relief on a big increase spread over several years?
Where employer contributions jump sharply from one period to the next, HMRC's manuals say the deduction may be spread. The test starts when the current period's payments are more than 210% of (2.1 times) the previous period's, and relief is spread only if the excess that results is £500,000 or more.
The Pensions Tax Manual sets it out in four steps: find the contributions paid in this and the previous period; adjust for any change in the length of the periods; compare them; and ask whether the excess is £500,000 or more. The excess is the part of the current period's contribution above 110% of the previous period's. If the excess is £500,000 or more, the relief on it is spread as follows.
| Excess contribution | Relief spread over |
|---|---|
| £500,000 or more but less than £1,000,000 | 2 years (half in the current period, half in the next) |
| £1,000,000 or more but less than £2,000,000 | 3 years |
| £2,000,000 or more | 4 years |
Several details narrow its reach. Each scheme is tested separately rather than on the combined total. Where no contribution was paid in the previous period, such as when an employer has only just set up a scheme, the manual says relief on the current period's contributions will not be spread. Contributions that pay for cost of living increases to pensions already in payment, or for future-service benefits of members joining in the current period, can be left out of the current-period figure. If the company stops trading before the spread finishes, it can choose to have the unrelieved balance deducted in its final period.
For a typical small company's pension payment, the figures are far below these levels, but a one-off catch-up payment into a larger scheme is where the test is worth running. The manual calls this a specialist area. A company near that spreading threshold can have the point explained on a free call-back; the short form here takes a minute.
What if the company has no trade, or stops trading?
A company that does not carry on a trade does not use the trade test. HMRC's Pensions Tax Manual says that where the employer is a company with investment business, the contributions are deductible as an expense of management, with the same rule that they count only in the accounting period in which they are paid, and that a contribution is not barred merely because it would otherwise be capital. HMRC's Company Taxation Manual (CTM08340 onwards) deals with these cases.
Closing a business has its own rules. For a contribution made as part of going out of business, particularly where there was no earlier contractual duty to make it, the Business Income Manual points to separate guidance (BIM46040). Payments to make good a scheme deficiency under section 75 of the Pensions Act 1995 are treated as contributions and, if the trade has ceased, as made on its last day.
Separately, Section 196A of the Finance Act 2004 gives HMRC power to restrict employer relief in cases tied to an employer-financed retirement benefits scheme: broadly, where a member's registered scheme benefits depend on not being paid a benefit expected from such a scheme, or where paying that benefit would reduce the transfer value of their registered scheme rights.
How do the annual allowance and the taper fit with the company deduction?
They are two separate tests. The deduction belongs to the company; the annual allowance belongs to the individual who is receiving the contributions. GOV.UK describes the annual allowance as the ceiling on pension saving in a tax year (6 April to 5 April) before tax is due. For defined contribution schemes it counts the total paid in "by you or anyone else (for example, your employer)". It is £60,000 for 2026/27, according to HMRC's pension rates page.
The allowance is reduced for high earners. For 2026/27, HMRC's rates page sets the taper limits at £200,000 of threshold income and £260,000 of adjusted income; the allowance is reduced only when both are exceeded. HMRC's guidance takes £1 off the allowance for each £2 of adjusted income over £260,000, and the allowance cannot fall below £10,000. Employer contributions feed in: adjusted income starts from net income and adds "the amount of pension savings your employer made for you", so a large company payment can lift adjusted income past £260,000. The taper still applies only if threshold income is over £200,000 as well. Threshold income is worked out differently: among other adjustments it adds back any reduction of employment income for pension provision through relevant salary sacrifice arrangements made after 8 July 2015, covered on the salary sacrifice page.
The related pages carry the detail: the annual allowance, the taper and adjusted income, employer contributions and adjusted net income, carry forward and the charge for going over. Whether the taper or carry forward bites for one director depends on income and pension history, and the call-back adviser can go through that at no cost.
Company pension contributions and corporation tax: common questions
Do companies pay tax on pension contributions?
Not as a charge on the contribution itself. A deductible contribution reduces the company's taxable profit. The conditions are that it is paid wholly and exclusively for the trade and is claimed for the period of account in which it is paid.
Can a company deduct payments into a final salary scheme?
Employer contributions to a registered defined benefit scheme follow the same trade test and the same paid-basis timing. The figure in the accounts can differ from what was paid, but only the cash paid is considered. The defined benefit page covers the scheme side.
Does salary sacrifice change the company's deduction?
The Business Income Manual accepts a higher employer contribution that results from a qualifying salary sacrifice arrangement as made wholly and exclusively for the trade, so it stays deductible. The employee-side effects are on the salary sacrifice tax page.
Can I claim the deduction in a different year from the payment?
For a trade, the manual says the deduction is for the period of account of payment and for no other period, apart from the spreading rules and a deficiency payment made after the trade has ceased, which counts on the last day of trading.
What happens if I stop trading after making a large payment?
If a spread is still running, HMRC's manual lets the company choose to deduct the unrelieved balance in the period when it ceases business, or to treat it as paid in equal daily instalments from the start of the period of payment to the date of cessation.
