Pension Contributions Timing: When the Bank Date Matters

1. Why Pension Contributions Work

An employer pension contribution is one of the cleanest tax trades available to an owner-managed company. It is deductible for Corporation Tax (reducing CT at the company's marginal rate), attracts no employer NIC (unlike a bonus), and the contribution is not taxable on the director as income when it is paid. The only tax is the income tax paid by the director when drawing the pension in retirement, at whatever rate applies at that point.

For a company at the marginal rate (26.5%), a £40,000 contribution reduces CT by £10,600 and produces £40,000 of retirement savings, versus extracting the same money as a dividend (no CT deduction) or as a bonus (13.8% employer NIC). The differential compounds, pension growth is tax-free inside the wrapper.

2. The Paid-Basis Rule

Unlike most other deductions, employer pension contributions are deductible on a paid basis (s.196 FA 2004), not an accruals basis. The contribution must have actually cleared the company bank account before the end of the accounting period for it to reduce that period's CT. A contribution accrued at year-end but paid in the new year is deductible only in the new year.

This is the single most common year-end mistake on pension planning. The board minute is dated pre-year-end, the contribution is instructed pre-year-end, but the bank payment clears a day or two into the new period. HMRC will look at the bank statement, not the intention. A week of buffer at year-end is the minimum; two weeks is safer.

3. Wholly and Exclusively

Employer contributions are deductible only where they are incurred wholly and exclusively for the purposes of the trade. For contributions to ordinary employees this is almost never in question. For director-shareholder contributions, HMRC can challenge the deduction where the total remuneration package is disproportionate to the work done for the company, essentially, where the "contribution" looks like a profit extraction rather than a genuine remuneration cost.

In practice, HMRC rarely challenges pension contributions on wholly-and-exclusively grounds where the director is actively engaged in the business and the total remuneration package (salary + bonus + pension + benefits) is broadly commensurate with what a third party would pay for the role. The risk increases where a spouse or non-working family member is the beneficiary of a large contribution, or where the contribution is out of scale with any other remuneration paid.

4. Annual Allowance and Carry-Forward

The annual allowance is £60,000 per individual (2024-25 onwards). Contributions above the allowance trigger an annual allowance charge on the individual, clawing back the tax relief. Unused allowance from the previous three tax years can be carried forward, provided the individual was a member of a registered pension scheme in those years and had not exceeded the allowance at that point.

• Current year: up to £60,000 standard allowance.
• Plus carry-forward: unused allowance from the three previous tax years, used oldest-first once the current year is maxed.
• Maximum in a single year: up to £200,000 or so, for an individual who has made no contributions in the three prior years and is still within the rules.

5. Tapering and the MPAA

The standard annual allowance tapers down for individuals with adjusted income above £260,000, by £1 for every £2 of income above the threshold, to a floor of £10,000. For director-shareholders taking large bonuses or where total taxable income is elevated in a particular year, the taper can materially reduce the allowance available for that year, though carry-forward from prior years is unaffected.

The Money Purchase Annual Allowance (MPAA) is triggered once a taxpayer has flexibly accessed a defined contribution pension, for instance, by taking a flexi-access drawdown income. The MPAA is £10,000 a year for money purchase contributions and blocks further carry-forward. This particularly affects directors who have already started drawing pension benefits while continuing to work.

6. Execution Mechanics

A clean year-end pension contribution has four documented steps: a board minute authorising the payment, a payroll instruction recording it as an employer contribution (not salary), a bank payment that clears before year-end, and a confirmation from the pension provider that the funds have been received and allocated.

Where the contribution is to a SIPP or SSAS, the provider's own acknowledgment is typically instantaneous. Where the contribution goes into a workplace scheme with a third-party administrator, the allocation can lag by days. The tax-deductible date is the date the money left the company; the allocation is a separate matter for the scheme records.
