How an employer pension contribution works

Your Ltd pays the pension scheme directly out of pre-tax profit. The contribution is a deductible business expense for corporation tax, reducing the company's CT bill at its marginal rate. It is NOT taxed as a benefit-in-kind on the contractor (s.307 ITEPA 2003), NOT subject to NI on either side (excluded from earnings under s.6(1) SSCBA 1992), and lands gross in the pension pot.

The alternative: take the same money as dividend

The opportunity-cost comparison: the same £1 of profit taken as additional dividend pays corporation tax first (19/26.5/25% depending on profit band), then the post-CT distributable amount pays personal dividend tax (10.75/35.75/39.35% depending on the contractor's band stack from existing salary + dividends). What lands in the bank is significantly less than the £1 of original profit.

The multiplier

The ratio of pension pot value to forgone net dividends. Typical contractor multipliers land between 1.4× (small- profits, basic-rate dividends) and 2.5× (marginal-relief band, higher-rate dividends). The headline number above shows the multiplier at your inputs; lower box shows the full company-side and personal-side breakdown.

Annual allowance + taper

All pension contributions in a tax year combined (employer + personal + made by anyone for you) count toward the same annual allowance of £60,000. Above this, the excess is taxed as income at your marginal rate, eliminating the saving on the over-the-line portion. Carry-forward of unused allowance from the prior 3 years is allowed.

Taper applies only at very high incomes: both threshold income (above £200k) AND adjusted income (above £260k) must be exceeded. The allowance reduces £1 per £2 over £260k of adjusted income, floored at £10k. Most contractors don't hit either threshold.

Frequently asked questions

What does the multiplier mean?
It's the ratio of pension pot value to forgone net dividends. A 1.65× multiplier means: every £1 of personal income you give up (by extracting via pension instead of dividend) lands as £1.65 in your pension pot. The reason it's above 1× is that the pension route avoids both corporation tax (deductible) AND dividend tax (no personal-side tax on employer contributions), whereas the dividend alternative pays both. Multiplier above 2× is common for higher-rate dividend taxpayers because they lose more to dividend tax under the alternative.
Why does the multiplier change with my profit level?
Because the corporation tax saved depends on your profit's marginal CT rate. Profits ≤ £50,000 pay 19% small profits rate. Profits £50,001–£249,999 sit in the marginal-relief band where each £1 of profit reduction effectively saves 26.5% (the small-profits rate plus a 1.5% top-up from the marginal-relief formula). Profits ≥ £250,000 pay the 25% main rate. Higher CT rate = more saved when you contribute = bigger multiplier. The personal-side dividend rate also matters: higher-rate dividends are 35.75% so the alternative loses more to tax, pushing the multiplier higher.
Why does my existing dividend amount matter?
The alternative scenario stacks the new dividend on top of your existing dividends, so the marginal dividend tax depends on your current band position. If your existing salary + dividends are below £37,700 of taxable income, the alternative dividend is taxed at the basic rate (10.75% in 2026/27). If you're already in higher-rate territory (above £37,700 taxable income), the alternative is taxed at 35.75%, making the dividend route considerably worse and the pension multiplier correspondingly higher.
What's the £60k annual allowance?
The total of all your pension contributions in a tax year, employer + personal + any made by anyone else for you, combined. Standard allowance is £60,000 since April 2023. Going over the allowance means the excess is taxed as income at your marginal rate (the 'annual allowance charge'), which eliminates the saving on the over-the-line portion. The calculator flags excess contributions in red. To go over £60k legitimately, use carry-forward of unused allowance from the prior 3 years.
When does the taper kick in?
Two thresholds must BOTH be exceeded before the taper applies: threshold income (income before pension contributions) > £200,000, AND adjusted income (income + employer pension contributions) > £260,000. Once triggered, the £60k allowance is reduced by £1 for every £2 of adjusted income above £260k, floored at £10,000. Most contractors at typical day rates don't hit either threshold. At very high day rates (£1,200/day+) the taper becomes relevant and the calculator surfaces a tapered allowance figure when applicable.
Can I really avoid all employee + employer NI?
Yes. Employer pension contributions are explicitly excluded from earnings under s.6(1) of the Social Security Contributions and Benefits Act 1992, meaning no Class 1 NI on either side. They're also excluded from benefit-in-kind treatment under s.307 of ITEPA 2003, so no income tax on the contractor either. This NI-free status is a major reason the multiplier beats both salary-extraction and dividend-extraction routes. A £20k bonus to yourself would attract ~£3k of employer NI plus all the personal-side tax/NI; £20k as employer pension contribution attracts zero NI.
What about the wholly-and-exclusively rule?
The contribution must be a reasonable business expense, i.e. proportional to the work the director does for the company. HMRC's published guidance accepts contributions up to the £60k allowance for full-time owner-managed contractor Ltds at typical day rates. Above that (using carry-forward), contributions of £100k+ are accepted but warrant explicit accountant sign-off and good documentation. Disproportionate contributions (e.g. £100k from a £30k profit Ltd with minimal trading) can be challenged. For most contractors this isn't a practical concern; for very high contributions, work with your accountant to document the rationale.
Why is this better than salary sacrifice?
Salary sacrifice (where the contractor sacrifices part of their salary in exchange for pension) is the right mechanic for umbrella contractors and permanent employees. For Ltd contractors, the employer-contribution route is structurally simpler (no payroll involvement, no salary impact, the Ltd just makes the payment direct) and equally tax-efficient. The two are different paths for different employment structures: see /calculator/salary-sacrifice-pension if you're umbrella or PAYE. Most Ltd directors should use this calculator's mechanic because their entire 'salary' is already optimised at £12,570, sacrificing further would push them below the personal allowance, which isn't useful.
