Employer Pension Contributions for Outside IR35 Contractors in 2026/27

Once you've dealt with the salary and dividend split, the next lever every outside IR35 contractor should understand is employer pension contributions. It's the biggest legal tax advantage the PSC structure retains in 2026/27, and it's meaningfully underused — usually because it isn't explained clearly.

Here's how it actually works, the numbers that matter, and where the traps are.

Why employer contributions beat everything else

Extraction from an outside IR35 PSC broadly happens through three channels: salary, dividends, and pension contributions. Comparing them from the same £1 of company profit:

Extraction method	Corp tax impact	Income tax / NI	Effective net to you
Salary (higher-rate)	Deductible at 19–25%	40% income tax + 2% employee NI + 15% employer NI	~40–45p per £1
Dividend (higher-rate, post-2026)	Not deductible (paid post-corp-tax)	35.75% dividend tax on 75/81p	~48–52p per £1
Employer pension contribution	Deductible at 19–25%	0% income tax at contribution point (deferred to drawdown)	~100p into the pension pot

The full pound goes into your pension. It's not free forever — you'll pay tax on withdrawal — but for someone in their 30s or 40s, that tax deferral is 20–30 years of compounding on the full amount instead of the after-tax amount. Compounded over that horizon, the pension route commonly ends up worth 3–4x what the equivalent dividend extraction would have produced.

The 2026/27 numbers you need

• Standard annual allowance: £60,000 (unchanged from 2024/25)
• Tapered allowance floor (for very high earners): £10,000
• Adjusted income threshold where tapering starts: £260,000
• Threshold income for taper eligibility check: £200,000
• Carry forward: up to 3 previous tax years of unused allowance
• Money Purchase Annual Allowance (if you've already flexibly accessed pension): £10,000

How to make an employer pension contribution

Mechanically simple. Two things happen:

1. The PSC transfers the contribution directly to your pension provider (SIPP, workplace pension, or standard personal pension). Note it as an employer contribution, not a personal contribution.
2. The accountant records the payment as a business expense (typically P&L line: pension contributions), deductible against corporation tax in that year.

That's it. No PAYE handling required (unlike personal contributions, which come from taxed net pay and get topped up by HMRC). No dividend documentation. No BADR question. The company pays into your pension, gets the corp tax deduction, and the money lands in your pot untaxed.

Carry forward — the big under-used lever

If your PSC didn't fully use its £60k allowance in previous years, the unused amount rolls forward for up to 3 years. Combined with the current year's £60k, that means a contractor with unused allowance from 2023/24, 2024/25, and 2025/26 could in principle make an employer contribution of up to £240,000 in a single 2026/27 tax year.

The 3-year carry forward rules to remember:

• Carry forward is available only if you were a member of a UK-registered pension scheme in each of the years being carried forward. Just having a personal pension you've never contributed to counts.
• You use the current year's allowance first, then eldest unused first (i.e. 2023/24 before 2024/25).
• Company contributions still need to pass the "wholly and exclusively" test. A large catch-up contribution is easier to defend if commercial performance in the current year justifies it (e.g. bumper trading year).

For contractors approaching retirement or planning a company closure, using carry forward to extract accumulated reserves into a pension shortly before winding up the PSC is often the single biggest legal tax play available.

The tapered annual allowance for high earners

For contractors with total income above £260,000 (adjusted income basis), the £60k allowance tapers down. The mechanics:

• Threshold income test: if your income (broadly your taxable income excluding pension contributions) is below £200k, you're safe from tapering regardless of adjusted income. Most contractors below the very top end fall here.
• Adjusted income test: if threshold income exceeds £200k, then adjusted income (broadly including employer pension contributions to your pot) is calculated. For every £2 of adjusted income above £260k, the £60k allowance reduces by £1.
• Once adjusted income hits £360k, the taper reaches the floor at £10k of allowance.

For most contractors this is irrelevant — the taper starts biting well above the typical PSC extraction range. If you're a £1,000+/day contractor with high sole earnings, you'll want your accountant to model the tapered position specifically.

The trade-off: locking money away until 55/57

The obvious downside: pension contributions are locked up. Access rules for 2026/27:

• Currently accessible from age 55.
• The minimum access age rises to 57 on 6 April 2028 for pension schemes not registered before that date.
• 25% of the pot is tax-free on withdrawal (up to a lump sum allowance of £268,275).
• The rest is taxed at your marginal income tax rate in the year drawn.

For most contractors this is a feature, not a bug — you're deferring tax at higher rates now for probably lower rates in retirement, while getting 20–30 years of compounding on the gross amount. But if you need liquidity for a house purchase, a business investment, or an early sabbatical, the pension route locks money away that a dividend extraction would leave available.

The pragmatic split for most contractors: extract enough via dividends to fund current living plus a reasonable safety buffer, extract enough via salary for state pension qualifying years, and route the meaningful surplus into the pension. The salary and dividends guide covers the current-income side of this framework.

Choosing the right pension vehicle

Three main options for a UK contractor employer pension:

• SIPP (Self-Invested Personal Pension). Highest flexibility. You choose the investments (funds, individual shares, some property). Providers like Hargreaves Lansdown, AJ Bell, and interactive investor offer contractor-friendly SIPPs with employer contribution acceptance. Best fit if you want investment control.
• Personal pension (non-SIPP). Provider chooses from a curated fund range. Simpler, cheaper, less to manage. PensionBee, Aviva, Standard Life are common contractor-friendly options.
• Workplace pension continuation. If you had a workplace pension from a previous employer, you can usually direct employer contributions from your new PSC into the same scheme. Often the path of least resistance if the scheme is reasonable.

Whichever route: check up front that the provider accepts employer contributions from a limited company. Some retail-focused providers only accept personal (individual) contributions, which forces you into a less efficient extraction chain.

Common mistakes contractors make with pension contributions

• Making personal contributions instead of employer contributions. Personal contributions come from taxed net pay and get topped up by HMRC. Employer contributions come from pre-corp-tax profits with the corp tax deduction. The maths generally favours employer contributions substantially. Set up the right one from day one.
• Ignoring carry forward on catch-up years. Contractors who took low dividends during a lean year (e.g. 2023/24 during a gap between contracts) often leave unused allowance on the table. Check with your accountant before assuming you're capped at £60k.
• Making a huge one-off contribution that fails the "wholly and exclusively" test. A £150k pension contribution in a year of £40k salary looks aggressive. Even with carry forward available, the "commensurate with role" question comes up. Ideally spread contributions or peg them to trading performance.
• Confusing MPAA with the standard allowance. Once you've flexibly accessed any pension (e.g. taken taxable income from a drawdown pot), the annual allowance for money purchase (defined contribution) schemes drops to £10k. This catches contractors who drew from an old workplace pot without realising the future consequence.
• Forgetting the timing. The contribution has to be paid into the pension provider before the tax year end to count against that year's allowance. Waiting until 5 April with a bank transfer is cutting it too fine — provider processing time can push the credit into the wrong tax year.

Worked example: £600/day contractor, higher rate

Assume: outside IR35, 220 days billed, £12,570 salary, no immediate cash needs beyond £60k of dividends, remainder available for pension.

Line item	Amount
Gross billing	£132,000
Less: salary + employer NI cost	£13,091
Available for extraction (pre-CT)	£118,909
Less: employer pension contribution £40k	£40,000
Remaining trading profit	£78,909
Less: corporation tax at 19%	£14,993
Retained profit distributable as dividends	£63,916
Net cash + pension: £60k dividend (post-tax) + £40k pension = £100k+

Comparison: extracting the whole £118k as dividends (higher-rate) would net roughly £92k cash but zero into a pension. The pension route sacrifices about £13k of current-year net income to put £40k (that would otherwise have been reduced to ~£25k after dividend tax) into the pension — and gets 20+ years of untaxed compounding on it.

The honest bottom line

For any outside IR35 contractor with income above basic band and no immediate need to extract every pound as cash, employer pension contributions are the default correct answer for the surplus. The corporation tax deduction plus the deferral of personal tax plus the compounding on the full amount makes the maths structurally better than any other extraction route.

The two things worth doing well: choose a pension provider that genuinely accepts employer contributions from your limited company (not all retail providers do), and use carry forward properly when trading years are uneven. Everything else is mechanical.
