Paying into a Pension Through Your Limited Company

Limited company directors can pay into a pension straight from company profits. The payment is normally deductible for corporation tax, carries no National Insurance and is not taxed as your income. This guide covers the wholly and exclusively test, the £60,000 annual allowance, carry forward, timing against your year-end, and a worked comparison with taking the same money as a dividend.

Yes, your limited company can pay into your pension, and for most contractors it costs less than paying in from your own account. An employer contribution is normally deductible when the company works out its corporation tax. It attracts no National Insurance and is not taxed as your income when it goes in. The main limits are the £60,000 annual allowance (plus any unused allowance carried forward), the wholly and exclusively test, and the rule that the company must actually pay the money inside its accounting period.

The rest of this guide explains how each of those works, what the numbers look like for a company with a £90,000 profit, and where directors tend to go wrong. It is written for the business owner who runs a contracting company and wants to know how to make pension contributions in the most tax-efficient way, and when.

What company pension contributions are

An employer contribution is a payment from the company's bank account to your pension provider. It comes out of company profits, not out of your salary or dividends, and it is paid gross: no tax is deducted before it reaches your pension pot.

That is different from personal pension contributions, where you pay in from money that has already been taxed and the provider claims basic-rate relief on it. GOV.UK explains that with relief at source the provider claims 20% from the government and adds it to your pot, and that higher-rate taxpayers claim the rest through Self Assessment.

Employer contributions versus a personal contribution for a company director

The difference matters most for limited company directors who take a modest salary and the rest as dividends. GOV.UK says tax relief on personal contributions is available up to 100% of your annual earnings. Dividends are not earnings for that purpose, so a low salary caps the relief on what you pay in personally.

An employer contribution has no such link. The annual allowance limits what goes in, but your salary does not. A company can pay more than your salary into your pension, and a director who takes dividends instead of salary can still receive company contributions. There is also no percentage of salary to aim for: the limits that matter are the annual allowance, the company's profit and cash, and whether the amount is reasonable for the role.

One condition does apply to who can receive them. Aegon's adviser guidance says an employer contribution cannot be paid for someone who is not an employee or former employee, and gives a non-employee shareholder as the example. A company can pay in for such a person, but it is treated as the individual's own contribution and the company gets no corporation tax relief. In practice, the person receiving the contribution needs to be genuinely working for the company, as an employee or a director.

The same is true if you are the only person on the payroll. Making contributions to a sole director's pension is allowed, provided the amount is commercially reasonable and passes the test below. A company with no employees other than the director has no duty to provide a workplace pension under auto-enrolment. If you take on staff, that changes: the company must enrol eligible workers and pay minimum contributions for them, so plan for that cost before you hire.

Is the contribution an allowable expense for HMRC?

Generally yes, provided it passes the wholly and exclusively test. ACCA's technical guidance states that a contribution to a registered pension scheme made wholly and exclusively for the purposes of the trade is an allowable deduction for corporation tax, citing section 54 of the Corporation Tax Act 2009. Relief is given by deducting the gross contribution from taxable profits before corporation tax is calculated, so this is how tax relief reaches the company.

In plain terms the contribution must be a reasonable part of what the company pays you for the work you do. Look at your whole remuneration package (salary, benefits and pension), not the pension contribution on its own. If the package is not excessive for the job, the contribution should qualify.

For an owner-managed company, HMRC's published approach is reassuring on one point. Where a controlling director is the driving force behind the company and instrumental in generating its income, the level of the package is a commercial decision, and a non-business purpose is unlikely. ACCA records that HMRC accepts a close company director's package where it is comparable with what unconnected employees doing work of similar value would receive.

Where HMRC looks harder:

  • Family members who do little work. A spouse or partner who is on the books but does little for the company is a classic enquiry.
  • Low salaries alongside inflated contributions. If salaries are below a commercial rate and pension contributions look inflated, an inspector can ask why. If tax or National Insurance planning was a purpose of the contribution, the full amount may not be allowable. The exception is salary or bonus sacrifice.
  • Loss-making companies. A large payment from a company with no profit can look like a way of moving money around rather than a business cost. Talk to your accountant before doing this.
  • Cessation. ACCA notes that payments made as part of arrangements for going out of business, with no earlier contractual obligation, do not meet the test.

Relief is not automatic. It is given at the discretion of the company's local tax office. A company can ask whether a proposed contribution will be relievable, but in practice the office may not be willing to confirm, particularly around the end of a tax year. The safer route is to keep your own record of the reasoning.

What to keep on file

You do not need a thick file. One page is enough:

  • why the contribution was made;
  • the profit figures;
  • confirmation that the company had the cash;
  • the carry forward calculation, if you used it;
  • your remuneration plan for the year.

Pay from the company bank account straight to the pension provider, never through your personal account first, because that would look like a personal contribution with different tax treatment. Keep a short board minute explaining the decision, together with the provider's confirmation of receipt. Make sure your accountant records the payment in the company's accounts as an allowable business expense. If HMRC asks why the company paid, say, £20,000 into your pension, you want a clear, dated answer.

Why it beats salary and dividends for tax efficiency

There are two layers of tax to avoid.

Salary. Salary attracts employer's and employee's National Insurance. The 2026-27 employer rate is 15% on pay above £5,000. On that basis, £20,000 paid as extra salary would cost the company a further £3,000 in employer's National Insurance, while £20,000 paid into a pension costs nothing extra. Employer pension contributions do not attract National Insurance contributions, unlike salary, bonuses, commission and taxable benefits in kind. There is no benefit in kind on the contribution either, because it goes straight into the pension. That is the heart of the tax efficiency: no tax and National Insurance on the way in.

Dividends. A dividend is paid out of profit that has already borne corporation tax, and then you pay dividend tax on it. For 2026-27 the dividend tax rate for a higher-rate taxpayer is up to 35.75%. Contributions through your limited company skip both layers.

For how salary and dividends interact in the first place, see our guide to salary and dividends for contractors in 2026-27.

How much corporation tax does the contribution save?

The saving depends on your company's rate. For 2026-27 a company pays 19% on profit up to £50,000 and 25% above £250,000. Between those figures marginal relief applies, and the effective rate on each extra pound of profit is 26.5%. If your profit falls in that band, each £1 of contribution saves 26.5p. Our guide to corporation tax rates and marginal relief shows how that band is calculated.

A worked example: £20,000 of company profits

Take a company with a 31 March 2027 year-end and a forecast taxable profit of £90,000 before any pension contribution. The director is a higher-rate taxpayer.

No pension contribution £20,000 employer contribution
Taxable profit £90,000 £70,000
Corporation tax £20,100 £14,800
Saving n/a £5,300
Net cost of the £20,000 to the company n/a £14,700

The corporation tax on £90,000 is 25% (£22,500) less marginal relief of £2,400. On £70,000 it is £17,500 less £2,700.

Now compare the alternative of taking that £20,000 of profit as a dividend:

Route What the director ends up with
Employer pension contribution £20,000 in the pension
Dividend, higher-rate taxpayer (35.75%) about £9,445
Dividend, basic-rate taxpayer (10.75%) about £13,120

The dividend figures come from taking the £20,000 of profit, deducting corporation tax at 26.5% to leave £14,700, and then deducting dividend tax. The pension receives the full £20,000.

There is a fair counterpoint. The pension money is locked away and taxed when you draw it. If you later take it with 25% tax-free and the rest taxed at 20%, you would receive about £17,000. If you were a higher-rate taxpayer in retirement, about £14,000. The pension still comes out ahead of the dividend in both cases, but only if you can leave the money alone for years.

How much can I contribute through my limited company?

The annual allowance

GOV.UK states that the annual allowance is the most you can save in your pension pots in a tax year (6 April to 5 April) before you pay a tax charge, and that it is £60,000 this tax year. It applies across all your private pensions and counts the total paid into a defined contribution scheme by you or anyone else, such as your employer. So yes, employer pension contributions count towards your annual allowance, as do your own personal contributions.

Two things can lower it:

  • The tapered annual allowance. GOV.UK says your allowance is reduced if your threshold income is over £200,000 and your adjusted income is over £260,000. The reduction is £1 for every £2 of adjusted income over £260,000, down to a minimum of £10,000.
  • The money purchase annual allowance. This applies once you have flexibly accessed a defined contribution pension, for example by taking cash from a flexi-access drawdown fund or an uncrystallised funds pension lump sum. It is £10,000 for 2026-27. It is not triggered if you only take the 25% tax-free lump sum or move into drawdown without taking income. If you plan to draw from a pension while still running the company, take advice first.

Carry forward

If you have not used your full allowance, GOV.UK says you may be able to carry over unused allowance from the previous three tax years. You use the current year's allowance first, then the oldest of the earlier years. You must have been a member of a registered pension scheme in each of those years, but you do not need to have contributed in them, and a scheme that was empty or held a small balance still counts. You also cannot have triggered the money purchase annual allowance.

For example, a director who paid £10,000 a year for three years has £50,000 unused from each. Add the current £60,000 and the potential is £210,000. There is no application and HMRC does not pre-approve the figure. You calculate it and apply it correctly.

The real ceiling is usually not the allowance. It is the company's profit, its cash, and the wholly and exclusively test applied to the year in which you pay.

If you go over

GOV.UK says that if you exceed your annual allowance, either you or your pension provider must pay the tax, and you report it in the "Pension savings tax charges" section of your Self Assessment return. The effect is to take back the relief on the excess. Because every source of contribution counts, check the position before a large payment, especially if you already contribute to your pension elsewhere.

Can I increase my pension contributions?

Yes, there is no need to commit to a fixed amount. You can change what the company pays, up to the allowance and what the company can afford. A sensible pattern is modest regular payments plus a planned top-up near the year-end once the profit is clear.

Timing: the company's year and the tax year are different clocks

There are two dates to manage.

The company's accounting period. ACCA's guidance says the corporation tax deduction for employer contributions is given for the period of account in which the employer pays them, and for no other period. The tax computation adds back whatever the accounts show for pension costs and substitutes a deduction on a paid basis. A promise to pay, or an accrual in the accounts, is not enough, and a payment made a few days after the year-end belongs to the next period however firm your intention was.

The tax year. The annual allowance runs 6 April to 5 April, whatever your company year-end. If your company year-end is not 31 March, you need the payment to work for both dates.

Some practical timing advice:

  • Providers can take a few days to process payments, so do not leave it to the last day. Decide about three months before the year-end and pay in the final month.
  • Leaving everything to the end can look arbitrary. Modest regular contributions plus a planned year-end top-up is steadier, and still lets you match the final profit figure.
  • Use spare cash only. Pension money is hard to get back before you are 55. One real case: a director made a large contribution just before year-end and then struggled to pay the corporation tax bill nine months later. Leave enough in the company for VAT, wages and tax.

One rarely noticed rule affects very large catch-up payments. ACCA explains that relief is spread over several periods where employer contributions increase by more than 210% from one period to the next, but only for an excess of £500,000 or more. If there were no contributions in the previous period, there is no spreading. Most contractors will never reach that, but it is worth knowing before a very large one-off.

What happens when you take the money out

Relief on the way in is not the whole picture.

  • You can start withdrawing from 55, rising to 57 from April 2028.
  • You can normally take 25% as a tax-free lump sum, up to a limit currently of £268,275 for most people.
  • The rest is taxed as income at your marginal rate in the year you take it.
  • From 6 April 2027, most unused defined contribution pension funds will fall inside the estate for inheritance tax, with limited exemptions such as benefits passing to a spouse or civil partner.

For scale, the full new State Pension for 2026-27 is £241.30 a week, or £12,548 a year, and only with 35 qualifying years of National Insurance. Few directors find that enough, which is why many choose to contribute to your pension through the company as well.

What are the downsides of a workplace pension?

The main ones are access and risk. The money is locked away until 55 (57 from 2028), it is taxed when you draw it apart from the tax-free part, and pension funds can fall as well as rise. The tax relief makes contributions more efficient but does not remove investment risk. If you need the money for a house deposit or to invest in the business in the next few years, a pension is the wrong place for it. For a retirement fund in your forties or fifties, it is a good one.

The Autumn Budget is due on 28 October 2026, and pensions are a frequent subject of change. If you are planning a large contribution, check the position again after it.

Mistakes we would avoid

  • Paying personally what the company could pay. A personal contribution from taxed income costs more than an employer contribution of the same size.
  • Paying after the year-end. The deduction falls in the next period.
  • Losing track of the allowance. Contributions from every source count.
  • Contributions that do not fit the role. A payment that bears no relation to your remuneration and the company's profit invites a question.
  • Triggering the money purchase annual allowance by taking taxable income from a defined contribution pot while still contributing.
  • Not recording it. Keep the provider's confirmation and your one-page note.
  • Choosing investments without advice. Your accountant can show you the tax effect, but investment choices belong with an independent financial adviser regulated by the Financial Conduct Authority.

Frequently Asked Questions

Can I make pension contributions through my limited company?

Yes. As a director of a limited company you can pay into a pension from the company. Within a reasonable overall pay package, HMRC generally accepts it as an allowable expense.

Are employer pension contributions tax-deductible for a limited company?

Usually, yes. If the contribution is wholly and exclusively for the purposes of the trade, it is deductible when the company calculates its corporation tax, and the deduction is given for the accounting period in which the company pays it.

Do employer pension contributions count towards my annual allowance?

Yes. The annual allowance covers the total paid into your defined contribution pensions in the tax year by you or anyone else, including your employer. It is £60,000 this tax year, before any taper or money purchase restriction, and carry forward may add to it.

Can I make a company pension contribution if I am the only employee?

Yes. A company whose only worker is the director can pay an employer contribution, provided it is commercially reasonable and passes the wholly and exclusively test.

Putting it into practice

The decision comes down to three numbers: your forecast profit for the year, the allowance you have available including carry forward, and the cash you can safely leave out of the company. Deplexify prepares accounts and tax for UK contractors, and the contractor accounting page sets out what that covers.
