Employer pension contributions in one paragraph: a contribution from your Ltd company to your pension is deductible against corporation tax, generally with no personal income tax, no NI, and no employee NI. Effective combined "tax cost" of getting £100 into your pension from company profits: about £75 (£25 of foregone CT). Compare to extracting via dividend (effective combined cost ~£55-60 net of CT and dividend tax for higher-rate payers), or salary (~£40-50 net of all taxes). Pension wins for any extraction above immediate cash needs.
How employer pension contributions work
- The company pays a defined sum directly to your registered pension scheme (SIPP or workplace pension).
- The contribution is treated as a business expense, deductible against corporation tax (saving 19% / marginal / 25% CT).
- You pay no income tax on the contribution — it never appears on your payslip.
- You pay no National Insurance on it — employer or employee.
- The pension scheme doesn't claim "basic-rate relief" on top — you've effectively had the relief at the company level (because it didn't pay tax on it).
This is different from a personal pension contribution (relief at source via SIPP), where you pay net of basic rate and the SIPP claims back 20% from HMRC.
The "wholly and exclusively" test
For a company pension contribution to be tax-deductible, it must be "wholly and exclusively for the purposes of the trade." HMRC's general view:
- Pension contributions for working directors at a "reasonable" level for their role are deductible.
- "Reasonable" is judged against what the director actually contributes to the business — their role, hours, expertise, and the company's profits.
- A £100,000 contribution from a small Ltd for a director taking minimal salary may face challenge if the director's role doesn't justify it.
- HMRC has historically rarely challenged contributions up to 100% of the director's "total remuneration package" if the director is genuinely active in the business.
In practice, contributions up to the annual allowance (£60,000) for active working directors are very rarely challenged.
The pension annual allowance interaction
Employer contributions count against your pension annual allowance (£60,000 in 2026/27), just like personal contributions:
- Standard AA: £60,000 per tax year. Combined cap on all pension inputs (personal + employer + tax relief).
- Tapered AA: from £200,000 threshold income / £260,000 adjusted income, AA reduces by £1 for every £2 of adjusted income above £260,000, floored at £10,000.
- Carry forward: unused AA from the previous 3 years can be carried forward, allowing larger one-off contributions.
- For directors with low personal income but high employer contributions, the tapered AA is rarely triggered — useful for accumulating large pension pots.
The 100% relevant earnings cap on personal contributions does NOT apply to employer contributions. So a director-shareholder taking a £12,570 salary can have a £60,000 employer pension contribution — the salary cap only restricts personal pension relief, not company contributions.
Worked example: high-profit director
Mr K is sole director of a tech consultancy. Company profit before director's salary: £200,000. Mr K has unused AA carry-forward of £120,000 from previous years (so total available AA: £60,000 + £120,000 = £180,000 this year).
Option A: Extract everything via salary + dividend.
- £200,000 profit, 25% CT (marginal): roughly £42,000 CT, £158,000 available
- Take £12,570 salary, employer NI £1,136
- Net distributable as dividend: roughly £145,000
- Personal income £157,570 = £45,000 of additional-rate territory
- Dividend tax breakdown: covered allowance, basic rate, higher rate, additional rate: total dividend tax ~£42,000
- PA fully tapered (lost ~£5,030 of allowance value at 40% = £2,000 additional tax)
- Net to director: roughly £115,000 from £200,000 profit (57.5%)
Option B: Salary £12,570 + employer pension £60,000 (current year only) + dividend rest.
- Salary £12,570, employer NI £1,136, pension £60,000
- Profit after these: £126,294. CT at marginal rate ~26.5%: roughly £33,500. Distributable: ~£92,800.
- Personal income: £12,570 + £92,800 = £105,370 (just over PA taper start, modest taper impact)
- Dividend tax: roughly £24,000 (basic + most in higher band)
- Net to director: £12,570 + £92,800 − £24,000 = £81,370 cash + £60,000 in pension = effectively £125,000+ equivalent (over 62%)
Option B retains more value because the £60,000 went into the pension wrapper essentially tax-free at extraction. When eventually drawn, it'll suffer some tax (25% tax-free, rest at marginal rate) but with planning that can be at basic rate in retirement — net retention ~80-90% of the original £60,000.
What's the catch?
Three things to be aware of:
- The money is locked up until age 55 (rising to 57 from 2028). If you need cash now, pension contributions don't help.
- Future tax on withdrawal. 25% tax-free, rest at marginal rate. If your retirement marginal rate is high (still working, big DB pension, large drawdown), the saving is smaller.
- Lump Sum Allowance. Capped at £268,275 in 2026/27 (the 25% tax-free cash limit). Large pensions may have this cap, reducing the "tax-free" portion proportionally.
For most director-shareholders, these are manageable trade-offs. Pension extraction is dominant from a tax perspective.
Practical mechanics
- Open a SIPP in your own name (Vanguard, AJ Bell, Hargreaves Lansdown, ii are common UK options).
- Give the SIPP provider your employer's details — many SIPP providers have specific employer-contribution forms.
- The company makes the contribution by BACS to the SIPP, with appropriate reference.
- The company books the payment as "employee benefit / pension" in the P&L (deductible).
- The contribution is reported on the company's Corporation Tax return.
- For Self Assessment, the contribution is NOT entered on your personal return at all — it never touched your income.
Common pension-from-company mistakes
- Confusing employer contributions with personal RAS contributions. Different mechanics, different tax effects. Employer contribution into the SIPP is the right route from a Ltd.
- Trying to retrospectively re-classify dividends as pension contributions. Doesn't work — must be a contemporaneous payment from the company.
- Overshooting the annual allowance without checking carry-forward. Excess contributions trigger Annual Allowance charge at your marginal rate.
- Forgetting the "wholly and exclusively" test in unusual cases. Massive contribution for a director with negligible activity may not be deductible.
- Putting pension contributions through the DLA rather than as a direct expense. If routed via DLA it creates a balance to clear, with knock-on tax effects.
