Contractor Pensions 2026/27: SIPP vs Employer Contributions vs Salary Sacrifice

There are three ways to fund your pension as a contractor, and they have very different tax outcomes. The most efficient route — employer contributions from your limited company — saves roughly £509 in combined tax for every £1,000 contributed. A personal SIPP contribution saves you around £400 on the same £1,000. The difference over a career is substantial. Here’s how each route works and when to use it.

Key facts: pensions in 2026/27

Annual allowance: £60,000 (or 100% of earnings, whichever is lower)

Carry-forward: up to 3 years of unused allowance

Employer contributions: Corporation Tax deductible, no NI, not personal income

Basic rate tax relief on personal contributions: claimed automatically

Higher rate relief: claim via Self Assessment

The three routes compared

	Employer contribution	Personal SIPP	Salary sacrifice
Who makes the contribution	Your Ltd company	You personally	You (via reduced salary)
Corporation Tax saving	Yes (19–25%)	No	No
NI saving	Yes (no employer or employee NI)	No	Yes (employee NI)
Income tax saving	Not direct (not personal income)	Yes (relief at source)	Yes (reduces taxable income)
Counts toward personal allowance taper	No	No (net pay arrangement)	No
Annual allowance limit	£60,000	£60,000	£60,000
Tax saved per £1,000	~£509	~£400	~£468

The employer contribution wins because it combines a Corporation Tax deduction on the gross contribution with the complete elimination of National Insurance — employer NI (15%) would otherwise be due on any equivalent salary payment.

Route 1: Employer contributions from your Ltd company

Your company pays directly into your pension from pre-tax profits. The contribution is deductible against Corporation Tax, doesn’t attract NI, and doesn’t appear on your personal Self Assessment as income. This means it also doesn’t push you into the personal allowance taper or trigger the High Income Child Benefit Charge.

Worked example: £30,000 employer pension contribution at £500/day

Without pension contribution:

Company profit: £102,295
Corporation Tax (marginal relief): £23,358
Dividends: £78,937
Dividend tax: £18,741
Take-home: £72,765

With £30,000 employer pension contribution:

Company profit: £102,295
Less pension contribution: £30,000
Taxable profit: £72,295
Corporation Tax: £13,756
Dividends: £58,539
Dividend tax: £12,037
Take-home (cash): £46,502
Pension pot receives: £30,000
Total wealth created: £76,502

The £30,000 pension contribution costs you £6,263 less in tax compared to taking the same amount as dividends (£76,502 total vs £72,765 take-home with no pension). The pension pot is £30,000 — but you’d have only kept roughly £17,000 net if you’d taken it as higher-rate dividends. You’ve put £30,000 into your pension for an effective cost of £17,000 in forgone take-home. That’s 43p of your own money for every £1 in the pot.

The contribution must be “wholly and exclusively” for business purposes — paying a working director’s pension meets this test in virtually all cases. Get your accountant to review if you’re making very large or irregular contributions.

Route 2: Personal SIPP contributions

You contribute directly from your personal bank account to a Self-Invested Personal Pension (SIPP). The pension provider claims 20% basic rate tax relief at source, adding it to your pot automatically. If you pay higher-rate tax, you claim the additional 20% through Self Assessment.

How it works on a £10,000 personal contribution:

You pay £8,000 into your SIPP
The SIPP provider claims £2,000 basic rate relief → £10,000 in your pension
On your Self Assessment, you claim a further £2,000 higher rate relief (if applicable)
Net cost: £6,000 out of pocket for £10,000 in pension

Tax saved per £1,000 in the pension: £400 (at higher rate). Compare this to the employer contribution route, where the equivalent saving is ~£509. The personal SIPP route is less efficient because you miss the Corporation Tax deduction on the contribution itself.

Personal SIPPs are still a good option if your company has limited profits in a given year but you have personal cash you want to invest, or if you want to consolidate old workplace pensions alongside your current contributions.

Route 3: Salary sacrifice

Salary sacrifice is technically an employee giving up salary in exchange for a pension contribution. For limited company directors, the practical effect is the same as making an employer contribution — you reduce your salary and the company pays the equivalent into your pension.

How it works: Instead of taking a salary of £12,570, you take £2,570 and direct £10,000 into your pension. Your personal income is £10,000 lower, so:

Employee NI saving: £800 (8% on £10,000 — though at £12,570 salary there’s no employee NI anyway)
In practice, for Ltd directors at the standard £12,570 salary, the NI benefit of salary sacrifice is minimal because NI thresholds mean there’s little NI to sacrifice

The bigger benefit is the Corporation Tax deduction. For Ltd directors, “salary sacrifice” and “employer contributions” achieve essentially the same outcome — the company pays into your pension from pre-tax profits. Don’t overcomplicate this distinction if you run a single-director company.

How much should you contribute?

This depends on your retirement timeline, existing pension savings, and how much of your profit you want to retain versus extract now. A few useful benchmarks:

Avoid the personal allowance taper

If your total income (salary + dividends) is approaching or exceeding £100,000, employer pension contributions can bring it back below the threshold. Each £1 contributed reduces your adjusted net income by £1. To bring income from £110,000 to £100,000 requires £10,000 in employer contributions — saving roughly £2,000 in taper tax plus the Corp Tax deduction. See the 60% trap in detail →

Carry-forward

If you haven’t used your full annual allowance in the previous three tax years, you can carry forward unused allowance and contribute more than £60,000 in one year. This is particularly useful after a high-earning year or if you’re planning to close your company (extracting retained profits into a pension before winding up can be highly tax-efficient).

The £60,000 ceiling

The annual allowance is £60,000 total across all pension contributions (employer + personal). If your employer contributes £60,000, you can’t add more personally. For most contractors, hitting £60,000 in a single year is ambitious — but it’s worth knowing the limit exists.

Setting up employer pension contributions

Choose a pension provider — NEST, PensionBee, Vanguard SIPP, or a full SIPP with investment options. Most accountants have recommendations.
Set up employer contributions in your payroll software (FreeAgent, Xero) — contributions are recorded as a company expense, reducing taxable profit.
Confirm the “wholly and exclusively” test with your accountant — routine pension funding for a working director always qualifies.
Record contributions in your company accounts as a pension expense before calculating Corporation Tax.

There’s no minimum contribution and no fixed schedule. Many contractors make lump-sum contributions at year-end, once the company’s profit position is clear, to maximise the Corp Tax saving.

How is this calculated?

Corporation Tax deductibility of employer pension contributions follows HMRC’s guidance on deductible expenses under the Corporation Tax Act 2009, s.1290. The “wholly and exclusively” test (CTA 2009, s.54) applies. Annual allowance limits are set by the Finance Act (£60,000 from 2023/24 onwards). Carry-forward rules are under the Finance Act 2004, s.228A. Personal SIPP relief at source operates under HMRC’s pension tax relief rules at GOV.UK.

Frequently asked questions

Can I make employer pension contributions if I’m the sole director?

Yes. Single-director limited companies can make employer pension contributions, and these are deductible against Corporation Tax. The “wholly and exclusively” test applies, but routine pension funding for a working director meets it without issue. Your accountant can confirm this for your specific circumstances.

Does contributing to a pension reduce my take-home pay?

In the short term, yes — money going into a pension isn’t available as cash today. But it reduces your tax bill significantly, so the effective cost is much less than the contribution amount. A £20,000 employer contribution at the higher-rate dividend level costs you roughly £9,380 in forgone take-home — but puts £20,000 into your pension.

What happens to my pension if I close my limited company?

Your pension is entirely separate from your company. Closing the company doesn’t affect your pension savings — they remain in your personal pension, protected by the pension scheme. Any final employer contribution before closure is still tax-deductible, and closing a company with significant retained profits can be a good opportunity to make a larger-than-usual pension contribution before winding up.

Can I access the pension before retirement?

Standard pension rules apply — you can access from age 57 (rising to 57 in 2028 from the current 55). You can take up to 25% as a tax-free lump sum. Accessing early or taking more than the tax-free allowance is subject to income tax. There’s no special treatment for contractors versus employees.

Is there a difference between a SIPP and a workplace pension for contractors?

The tax treatment is the same. SIPPs give you more investment choice and are typically better suited to contractors who want to self-direct their investments. Workplace schemes (like NEST) are simpler and have lower charges on modest contributions. For employer contributions from a Ltd company, most contractors use a SIPP or a stakeholder pension — these accept employer contributions straightforwardly.
