How pension contributions reduce your Corporation Tax bill
Employer pension contributions are an allowable expense for your limited company. They reduce your taxable profit, which lowers your Corporation Tax bill. Here’s how the relief works.
When your limited company pays into your pension, the payment is treated as a business expense. It comes off your profit before Corporation Tax is worked out, so your company pays tax on a smaller figure and your bill goes down.
The money also moves out of the company and into a pension in your name, with no National Insurance to pay on the way in.
From an accounting point of view, it’s one of the most tax-efficient ways to take value out of your business. For you, it means more money going towards your financial freedom.
How the relief works
Corporation Tax is charged on your company’s taxable profit. Employer pension contributions sit in your accounts alongside salaries and other staff costs, so they reduce that profit in the same way.
How much tax you save depends on your profit level. For the financial year starting 1 April 2026:
profits up to £50,000 are taxed at 19%
profits over £250,000 are taxed at 25%
profits in between pay 25% less marginal relief, which works out at 26.5% on each pound in that band
In that middle band, every pound you pay into your pension saves 26.5p in Corporation Tax. So…
If your company makes £100,000 profit and pays £20,000 into your pension.
Corporation Tax on £100,000: £22,750
Corporation Tax on £80,000: £17,450
Tax saved: £5,300
The full £20,000 goes into your pension, and the real cost to the company is £14,700.
How this compares with salary and dividends
Each way of taking money out of your company is treated differently in your accounts:
Salary reduces Corporation Tax. The company pays employer’s National Insurance at 15% on earnings above £5,000, and you pay Income Tax and employee National Insurance.
Dividends are paid from profit after Corporation Tax, so they give no Corporation Tax saving. You pay dividend tax personally.
Employer pension contributions reduce Corporation Tax, with no employer or employee National Insurance and no Income Tax when they’re paid in. Tax applies later, when you draw from the pension.
Most directors use a mix of all three. The right balance depends on your profits, your cash flow and what you need to live on. Our guide on salary and dividends covers the first two in more detail.

What HMRC looks for
To be deductible, a contribution has to be made wholly and exclusively for the purposes of your trade. HMRC’s guidance says contributions to a registered pension scheme will normally meet this test.
If you own and run the company, HMRC looks at whether your overall pay package, including pension contributions, is in line with the work you do for the business. The same applies to family members on the payroll. Their contributions should reflect the role they actually carry out.
When your company gets the relief
Relief is given in the accounting period the contribution is paid. If you accrue a contribution at your year end and pay it after, the deduction falls into the following year. Paying before your year end brings the saving into the current year’s tax bill.
There’s one exception. If a contribution is much larger than the year before (as of October 2026, more than 210% of the previous year’s figure, with an excess of £500,000 or more), HMRC spreads the relief over up to four years. Most owner-managed companies won’t come near this.
Are there limits?
For Corporation Tax, there’s no set cap on what your company can pay in, as long as it passes the wholly and exclusively test.
The limit sits with you personally. Your annual allowance is £60,000 for 2026/27 and it covers all contributions made for you, including your company’s.
You can carry forward unused allowance from the previous three tax years, provided you were a member of a registered pension scheme in those years. If your adjusted income is over £260,000, your allowance reduces, down to a minimum of £10,000.
Employer contributions can also be higher than your salary. Personal contributions only get tax relief up to the level of your earnings, so for directors on a low salary, company contributions allow larger amounts to go in.
Keeping it affordable
A pension contribution is real cash leaving your business. Up-to-date management accounts show whether your profits and cash flow can support the amount you’re planning, and when in the year it makes sense to pay it.
Choosing a pension scheme and how it’s invested is regulated financial advice. The accounting side is about how much goes in, when it’s paid and what it saves your company.
