Pension Contributions Through Your Limited Company 2025/26: The Complete Guide
How to make pension contributions as a UK limited company director. Save Corporation Tax, avoid NI, and build retirement wealth tax-efficiently in 2025/26.
Quick Answer
Employer pension contributions are one of the most tax-efficient ways to extract money from your company - no Income Tax, no NI, and full Corporation Tax relief.
Making pension contributions through your limited company is one of the most tax-efficient ways to extract profits. Your company pays no Corporation Tax on contributions, you avoid all National Insurance, and the money grows tax-free until retirement.
For most UK limited company directors, employer pension contributions beat salary or dividends hands down. A £10,000 contribution costs your company exactly £10,000, but taking that same amount as salary would cost over £15,000 after tax and NI. This guide explains exactly how to maximise your pension contributions while staying within HMRC rules.
Why Pension Contributions Are So Tax-Efficient
When your limited company makes a pension contribution on your behalf, you benefit from triple tax savings:
- No Corporation Tax - Contributions are a deductible business expense, saving 19-25% immediately
- No Employer's National Insurance - Unlike salary, there's no 15% NI charge
- No Employee's National Insurance - You don't pay the 8% that applies to salary above £12,570
- No Income Tax on the contribution - Tax is deferred until you draw the pension
The result? Your company can put £10,000 into your pension for a true cost of £10,000. To get £10,000 as salary would cost considerably more.
Company Contributions vs Personal Contributions
There are two ways to fund your pension as a limited company director. Understanding the difference is crucial for tax planning.
| Factor | Company Contribution | Personal Contribution |
|---|---|---|
| Corporation Tax | Full relief (19-25% saved) | No relief |
| Employer's NI | None | N/A (but salary needed first) |
| Employee's NI | None | Paid on underlying salary |
| Income Tax | None (deferred) | Relief at marginal rate |
| Pension pot receives | Full amount | Amount + tax relief |
| Annual Allowance impact | Counts in full | Counts in full |
| Relevant earnings required | No | Yes (need salary first) |
Bottom line: Company contributions are almost always more tax-efficient than personal contributions for limited company directors.
How Company Pension Contributions Work
When your limited company makes a pension contribution directly to your pension scheme:
- Company Decides to Contribute - Via board minute or director's resolution, documented in writing
- Payment to Pension Provider - Your company pays directly into your SIPP or workplace pension, made gross with no deductions
- Corporation Tax Relief - The contribution reduces your taxable profits, lowering your CT bill
- Pension Grows Tax-Free - All growth is completely tax-free until withdrawal
The Tax Savings Explained
Corporation Tax saving:
- At 19% (small profits rate): Save £1,900 per £10,000 contributed
- At 25% (main rate): Save £2,500 per £10,000 contributed
National Insurance saving:
- Employer's NI avoided: £1,500 per £10,000 (15% that would apply to salary)
- Employee's NI avoided: £800 per £10,000 (8% that would apply to salary above threshold)
Total immediate tax advantage: Up to £4,800 saved on every £10,000 contributed versus taking salary.
How Personal Pension Contributions Work
Personal contributions work differently. You receive salary (taxed and NI'd), contribute from net pay, and your pension provider claims 20% tax relief. Higher rate relief is claimed via Self Assessment.
The problem: to make a personal pension contribution, you need "relevant UK earnings" - primarily salary. But earning that salary incurs Income Tax (20-45%), Employee's NI (8%), and Employer's NI (15%). Even with pension tax relief, you've already lost money to National Insurance that can't be recovered.
Personal contributions only make sense when you have employment income from elsewhere, insufficient company profits, or you're a basic rate taxpayer with no company profits to contribute from.
Worked Example: £10,000 Pension Contribution
Let's compare the true cost of getting £10,000 into your pension via each route.
Route 1: Company Contribution
| Item | Amount |
|---|---|
| Company contribution to pension | £10,000 |
| Corporation Tax saved (25%) | -£2,500 |
| Employer's NI | £0 |
| Net cost to company | £7,500 |
| Amount in your pension | £10,000 |
The company pays £10,000, but after CT relief, the true economic cost is £7,500. Your pension receives the full £10,000.
Route 2: Via Salary Then Personal Contribution
To make a £10,000 personal contribution, you first need relevant earnings of at least £10,000 in salary.
| Item | Amount |
|---|---|
| Gross salary needed | £10,000 |
| Employer's NI (15% on £5,000+) | £750 |
| Total company cost | £10,750 |
| Employee's NI | £0* |
| Income Tax | £0* |
| Net salary received | £10,000 |
| You contribute to pension (net) | £8,000 |
| HMRC adds 20% tax relief | £2,000 |
| Amount in your pension | £10,000 |
*Assuming this is your only salary and falls within Personal Allowance.
Even in this best-case scenario (salary within Personal Allowance), the company contribution route saves £750 in Employer's NI.
Route 2B: If Already Using Personal Allowance
If you're already taking the optimal £12,570 salary (see our director's salary guide), additional salary for pension contributions gets expensive:
| Item | Amount |
|---|---|
| Additional gross salary needed | £12,500 |
| Employer's NI (15%) | £1,875 |
| Total company cost | £14,375 |
| Employee's NI (8%) | £1,000 |
| Income Tax (20%) | £2,500 |
| Net salary received | £9,000 |
| You contribute to pension (net) | £8,000 |
| HMRC adds 20% tax relief | £2,000 |
| Amount in your pension | £10,000 |
The company pays £14,375 to put £10,000 in your pension. Compare this to £10,000 (£7,500 after CT relief) via the company contribution route.
Difference: £6,875 more via the salary route.
Annual Allowance Rules
The annual allowance limits how much you can contribute to pensions each tax year with tax relief.
2025/26 Annual Allowance: £60,000
This limit applies to:
- Company contributions (employer contributions)
- Personal contributions (including tax relief)
- Any contributions made on your behalf
Important: The allowance is the total from all sources, not per contribution type.
Relevant Earnings Cap
For personal contributions, tax relief is limited to 100% of your relevant UK earnings. If your salary is £12,570, you can only get tax relief on personal contributions up to £12,570.
Company contributions don't have this restriction - they're limited only by the overall annual allowance and the "wholly and exclusively" test for Corporation Tax relief.
Carry Forward Unused Allowance
If you haven't used your full £60,000 allowance in previous years, you can carry forward unused amounts for up to three years.
| Tax Year | Allowance | Used | Unused |
|---|---|---|---|
| 2022/23 | £40,000 | £5,000 | £35,000 |
| 2023/24 | £60,000 | £10,000 | £50,000 |
| 2024/25 | £60,000 | £12,000 | £48,000 |
| 2025/26 | £60,000 | - | £60,000 |
Available in 2025/26: £60,000 (current year) + £35,000 + £50,000 + £48,000 = £193,000
This makes large one-off contributions possible when your company has a particularly profitable year.
Conditions for Carry Forward
To use carry forward:
- You must have been a member of a registered pension scheme in the year you're carrying forward from
- You must have had relevant UK earnings in that year (though £1 is technically enough)
- Current year's allowance must be used first
Tapered Annual Allowance for High Earners
If your income exceeds certain thresholds, your annual allowance is reduced.
The Thresholds (2025/26)
- Threshold income: £200,000 (income before pension contributions)
- Adjusted income: £260,000 (income including employer pension contributions)
If your threshold income is under £200,000, tapering doesn't apply regardless of adjusted income.
How Tapering Works
For every £2 of adjusted income over £260,000, your annual allowance reduces by £1.
| Adjusted Income | Annual Allowance |
|---|---|
| Up to £260,000 | £60,000 |
| £280,000 | £50,000 |
| £300,000 | £40,000 |
| £320,000 | £30,000 |
| £340,000 | £20,000 |
| £360,000+ | £10,000 (minimum) |
Calculation Example
Director with:
- Salary: £50,000
- Dividends: £180,000
- Employer pension contribution: £60,000
Threshold income: £50,000 + £180,000 = £230,000 (over £200,000, so tapering may apply)
Adjusted income: £230,000 + £60,000 = £290,000
Reduction: (£290,000 - £260,000) / 2 = £15,000
Tapered allowance: £60,000 - £15,000 = £45,000
This director has exceeded their tapered allowance by £15,000 and will face a tax charge.
Planning Around the Taper
If you're approaching these thresholds:
- Consider spreading contributions across years
- Use carry forward from lower-income years
- Review timing of dividend declarations
- Ensure you don't accidentally exceed the allowance
When You Can't Use Company Contributions
Company pension contributions must pass the "wholly and exclusively for the purposes of trade" test for Corporation Tax relief. There are situations where this becomes problematic.
Insufficient Profits
If your company has minimal or no profits, large pension contributions may be challenged by HMRC as not being "wholly and exclusively" for business purposes.
Rule of thumb: Contributions up to £60,000 are generally accepted for working directors, but contributions that would create or increase a company loss may be questioned.
Non-Working Directors
If you're a non-working or sleeping director, justifying significant pension contributions is harder. HMRC may view them as profit extraction rather than genuine remuneration.
Irregular or Excessive Contributions
Contributions that are wildly disproportionate to your salary or role may attract scrutiny. A director paying themselves £12,570 salary but contributing £200,000 to their pension might face questions.
What To Do
- Keep contributions proportionate to your role and company profits
- Document the business rationale (retention, reward for services)
- Consider spreading large contributions across years
- Take professional advice for contributions over £60,000
Timing Considerations
When you make pension contributions affects when you get tax relief.
Corporation Tax Relief Timing
To get Corporation Tax relief in a particular accounting period, contributions must be:
- Paid (not just accrued) by the accounting year-end, AND
- Reported on your Corporation Tax return
Example: Your company year-end is 31 March 2026. To get CT relief in your 2025/26 accounts, ensure the pension contribution is paid by 31 March 2026.
Year-End Planning
Many directors make a large pension contribution just before their accounting year-end. This:
- Reduces Corporation Tax for that year immediately
- Uses up annual allowance efficiently
- Allows assessment of annual profits before committing
Caution: Don't leave it too late. Pension provider processing times vary, and contributions must clear by your year-end date.
Personal Tax Year
For your personal income tax position (relevant for tapered annual allowance calculations), the tax year runs 6 April to 5 April.
Company contributions count against your annual allowance in the tax year they're paid, regardless of your company's accounting period.
SIPP vs Workplace Pension for Directors
SIPP (Self-Invested Personal Pension): Full investment choice (stocks, funds, commercial property), consolidate pensions from previous employment, greater control. Higher platform fees (typically £100-200/year) and requires investment knowledge. Best for directors wanting investment control or substantial pension pots.
Workplace Pension / Master Trust: Simple to set up, often lower fees for standard funds, meets auto-enrolment requirements. Limited investment choices and flexibility. Best for directors preferring simplicity or smaller contributions.
Most directors with significant pension contributions opt for a SIPP. You might maintain both - a workplace scheme for regular small contributions and a SIPP for larger annual contributions.
Common Mistakes to Avoid
Exceeding the Annual Allowance - You pay Income Tax at your marginal rate on excess contributions. Track contributions from all sources.
Missing the Accounting Year-End - Corporation Tax relief requires payment by year-end. A contribution on 1 April for a 31 March year-end won't get relief that year.
Forgetting Carry Forward - You can carry forward up to three years of unused allowance for significant tax-efficient contributions.
Making Personal Contributions Instead of Company - Unless you have unusual circumstances, company contributions are almost always more tax-efficient.
Not Documenting Contributions Properly - Keep board minutes authorising contributions to support the "wholly and exclusively" test.
Ignoring the Money Purchase Annual Allowance - If you've flexibly accessed pension benefits, your allowance drops to £10,000.
Timing Mismatch Between Tax Years - Your company year-end and tax year (5 April) likely differ. Be clear on both timelines.
Assuming All Providers Accept Employer Contributions - Some legacy schemes don't. Verify with your provider first.
Frequently Asked Questions
Can my limited company contribute to my pension?
Yes, and this is usually the most tax-efficient way to fund your pension as a director. Your company can contribute directly to your SIPP or workplace pension. The contribution is a tax-deductible business expense, saving Corporation Tax, and there's no National Insurance on pension contributions (unlike salary). The money grows tax-free in your pension until you draw it in retirement.
How much can my company contribute to my pension in 2025/26?
The annual allowance for pension contributions is £60,000 for 2025/26. This is the maximum that can be contributed with tax relief. However, you can carry forward up to three years of unused allowance, potentially allowing contributions of over £200,000 in a single year. High earners with adjusted income over £260,000 may have a reduced (tapered) allowance.
Do I pay National Insurance on company pension contributions?
No. Unlike salary, employer pension contributions don't attract Employer's National Insurance (15%) or Employee's National Insurance (8%). This is one of the key reasons pension contributions are so tax-efficient - a £10,000 pension contribution avoids up to £2,300 in NI that would apply if you took the same amount as salary.
Are company pension contributions tax-deductible?
Yes, employer pension contributions are allowable deductions for Corporation Tax purposes. This reduces your company's taxable profits, saving 19-25% in Corporation Tax depending on your profit level. Combined with the NI savings, this makes pension contributions one of the most tax-efficient ways to extract profits from your limited company.
What's the difference between employer and personal pension contributions?
Employer contributions are paid directly by your company to your pension - they're tax-deductible for Corporation Tax and free of National Insurance. Personal contributions are made from your after-tax income (typically salary) - you get Income Tax relief via your pension provider and Self Assessment, but you've already paid NI on the underlying salary. For limited company directors, employer contributions are almost always more tax-efficient.
Can I make a pension contribution if my company isn't profitable?
You can, but it's riskier from a tax perspective. Pension contributions must be "wholly and exclusively for trade purposes" to qualify for Corporation Tax relief. Contributions that create or increase a company loss may be challenged by HMRC. If your company has no profits, consider whether making pension contributions is prudent and take professional advice.
Does my pension contribution reduce my Corporation Tax?
Yes. Employer pension contributions reduce your company's taxable profits, directly lowering your Corporation Tax bill. At the 25% main rate, a £10,000 pension contribution saves £2,500 in Corporation Tax. At the 19% small profits rate, it saves £1,900. This relief is in addition to the National Insurance savings.
Can I still take salary and dividends alongside pension contributions?
Absolutely. The optimal strategy for most directors combines all three: take the £12,570 salary to maximise your Personal Allowance and maintain State Pension credits, make employer pension contributions up to the annual allowance for maximum tax efficiency, and take dividends from remaining profits. See our guides on optimal director's salary and salary vs dividends for the complete strategy.
