Paying into a pension is one of the most tax-efficient things most people can do with their money — and yet it's often overlooked, or left until the end of the year as an afterthought. Whether you're an individual trying to keep more of your income, a parent wanting to protect your Child Benefit, or a company director deciding how to pay yourself, pension contributions can save a surprising amount of tax. Here's how the main benefits work, in plain English.
How pension tax relief works
When you pay into a personal pension, the government effectively refunds the income tax you paid on that money. Contributions receive tax relief at your highest (marginal) rate of tax. A basic-rate taxpayer gets 20% relief, a higher-rate taxpayer 40%, and an additional-rate taxpayer 45%.
In practice a basic-rate taxpayer's £100 contribution only costs them £80, because £20 of relief is added automatically. Higher and additional-rate taxpayers claim the extra relief through their tax return. So before you even consider the benefits below, every pound you contribute is already working harder than a pound left in your bank account.
Escaping the £100,000 "60% tax trap"
Once your income climbs above £100,000, your tax-free personal allowance is gradually withdrawn — reduced by £1 for every £2 you earn over that figure, disappearing entirely at £125,140. The effect is brutal: income in that band is effectively taxed at around 60%, because you're losing your allowance at the same time as paying higher-rate tax.
Pension contributions are one of the cleanest ways out of this trap. Because personal pension contributions reduce your adjusted net income — the figure HMRC uses for the taper — paying enough into your pension to bring your income back below £100,000 can restore your full personal allowance. In that band you can end up getting tax relief worth roughly 60% on the contribution. Few other planning steps are as efficient.
Protecting your Child Benefit
Families face a similar issue with the High Income Child Benefit Charge (HICBC). Where the higher earner in a household has adjusted net income above £60,000, some of the Child Benefit is clawed back through a tax charge, and it's withdrawn completely once income reaches £80,000.
Here again, pension contributions reduce the adjusted net income that the charge is based on. By paying into a pension, a parent can bring their income back under the threshold — keeping more (or all) of the family's Child Benefit while also building up their retirement pot. You get the pension and the Child Benefit, instead of losing the benefit to the tax charge.
Company pension contributions for owner-directors
If you run your own limited company, there's an extra layer of benefit. Rather than paying yourself more salary or dividends and then contributing personally, the company can pay employer pension contributions directly on your behalf — and this is often the most tax-efficient way of all to extract value from the business.
- Corporation tax saving: employer pension contributions are normally an allowable business expense, so they reduce the company's taxable profit and its corporation tax bill, provided they're commercially justifiable (the "wholly and exclusively" test).
- No National Insurance: unlike a salary or bonus, employer pension contributions attract no employer's National Insurance and no employee's National Insurance. That alone can make them cheaper than paying the same amount as extra salary.
- No personal tax on the way in: an employer contribution isn't treated as taxable income for you personally (within your allowances), so money moves from the company into your pension without an income tax charge.
- Bypasses the dividend route: profits paid out as dividends have already suffered corporation tax and then face dividend tax in your hands. An employer pension contribution avoids that double hit.
For many owner-directors, employer pension contributions are the single most efficient way to move profit out of the company and into their own long-term wealth.
How much can you pay in?
The benefits are generous, but there are limits to keep in mind:
- Annual allowance: most people can contribute up to £60,000 a year across all pensions (including employer contributions) while still getting tax relief. Personal contributions are also capped at your relevant earnings.
- Carry forward: unused allowance from the previous three tax years can often be carried forward, allowing a larger one-off contribution — useful in a strong year.
- Tapered allowance for high earners: very high earners have a reduced annual allowance, so large contributions need checking first.
- Already drawing a pension: if you've flexibly accessed a pension, a lower "money purchase" allowance may apply.
Thresholds and allowances change from time to time, so always confirm the current figures before acting.
Getting it right
Pensions sit at the intersection of tax planning, profit extraction and long-term financial planning, and the rules — especially the annual allowance taper and the "wholly and exclusively" test for company contributions — reward getting the detail right. As ICAEW Chartered Accountants working with individuals and owner-managed businesses across Kent and the UK, we can model the numbers, work out the most efficient mix of salary, dividends and pension, and coordinate with your financial adviser so the contributions do exactly what you need them to.
