Pension Tax Relief: How It Works and How to Claim Your Allowance
Understanding the pension annual allowance is essential if you want to make the most of pension tax relief without incurring unexpected tax charges. For many people, especially higher earners or those making large one-off contributions, the rules are more complex than they first appear.
Below, we explain how the annual allowance works, how much you can pay into a pension each year, what counts towards the limit, and what happens if you exceed it. We also cover carry forward, reduced allowances, and how to manage or avoid an annual allowance tax charge.
The pension annual allowance is the maximum amount that can be contributed to your pensions each tax year while still benefiting from tax relief. It applies to the total value of contributions made for you, not just what you personally pay in.
This includes:
The annual allowance applies across all your pensions combined, including workplace pensions, personal pensions, SIPPs and defined benefit schemes.
For most people, the standard annual allowance is currently £60,000 per tax year, but this can be lower depending on your income or circumstances.
How much you can pay into a pension each year depends on both the annual allowance rules and your personal earnings. While pensions are one of the most tax-efficient ways to save for retirement, there are limits on how much can be contributed in a single tax year. In most cases, the maximum you can contribute and receive tax relief on is the lower of:
Key points to be aware of:
Understanding your earnings position and total contributions is essential before making any payments.
Many people assume the allowance only applies to what they personally pay in, but that’s not the case. The annual pension allowance covers the total value of pension input.
This includes:
What it doesn’t include:
It’s the input into pensions during the tax year that matters, not the value of your pension pot.
For defined contribution pensions, contributions are measured by the actual amounts paid into the scheme during the tax year. This includes your own contributions, employer contributions, and any tax relief added by HMRC.
For defined benefit pensions, the calculation works very differently. Instead of looking at cash paid in, HMRC measures the increase in the value of the pension benefits you have built up over the year, using a specific formula. This can make it harder to predict how much of your annual allowance is being used.
Pension Input Period
Pension contributions are assessed over a pension input period, which runs in line with the tax year from 6 April to 5 April.
This means that:
Keeping track across multiple pensions is one of the most common reasons people accidentally exceed their allowance.
If your pension input exceeds your available annual allowance pension limit, the excess is subject to an annual allowance tax charge.
The annual allowance tax charge works by cancelling out the tax relief on any contributions above your permitted limit. The charge is applied at your highest rate of income tax and is usually declared and settled via self-assessment.
Example
If you exceed your allowance by £10,000 and pay tax at 40%, the tax charge would be £4,000.
In some cases, your pension scheme can pay the charge on your behalf (known as scheme pays), but this reduces your pension benefits.
Carry forward allows you to use unused allowance from the previous three tax years, potentially increasing how much you can contribute now.
How carry forward works
You can use carry forward if:
Unused allowance is used in chronological order, starting with the oldest year.
Example
If you used only £20,000 of your allowance in each of the last three years, you could potentially carry forward £120,000, allowing a very large one-off contribution.
Carry forward is one of the most effective planning tools, but it requires accurate records and careful calculation.
Not everyone has access to the full £60,000 allowance. Two reduced allowances can apply.
Tapered Annual Allowance
The tapered annual allowance affects higher earners.
You may be subject to tapering if:
If tapering applies, your allowance is reduced by £1 for every £2 of income above the threshold, down to a minimum of £10,000.
This can catch people out, particularly those with variable income or large bonuses.
Money Purchase Annual Allowance (MPAA)
The money purchase annual allowance applies once you have flexibly accessed a defined contribution pension.
Key points:
Taking taxable income (not just tax-free cash) can trigger the MPAA.
Defined benefit (DB) pensions are measured very differently from defined contribution schemes. Instead of looking at how much money is paid into the pension, HMRC assesses how much your promised retirement benefit has increased over the tax year.
How DB pension input is calculated
Rather than tracking contributions, the pension input amount is calculated using a formula that broadly considers:
This approach reflects the long-term value of the guaranteed income you’re building, rather than the cost of funding it in that year.
What this means in practice
Because the calculation is linked to benefit growth rather than contributions:
Annual allowance breaches are particularly common in public sector defined benefit schemes, such as NHS, teachers’ or civil service pensions, where salary progression can significantly increase pension benefits in a single year.
Yes. Employer contributions always count towards your pension annual allowance, and they must be included when assessing whether you are at risk of exceeding the limit.
Employer contributions include:
Because employer payments are often higher than personal contributions, they can make up a significant proportion of your total pension input. This means it’s possible to exceed your allowance even if your own contributions feel small.
This is particularly important if you receive bonuses, benefit from enhanced employer matching, or use salary sacrifice, as these can all increase the total amount counted towards the allowance in a single tax year.
Certain situations make it more likely that your pension contributions could exceed the pension annual allowance. This risk is not always obvious, particularly if contributions are made automatically or calculated differently across multiple schemes.
You may be at higher risk if any of the following apply to you:
If one or more of these situations apply, it’s important to take proactive steps to assess your position before the end of the tax year.
Practical steps to help you stay in control include:
Regular checks and early action significantly reduce the risk of unexpected annual allowance tax charges and allow more time to plan contributions effectively.
It isn’t always possible to avoid an annual allowance charge entirely, particularly if your income or pension benefits fluctuate. However, with careful planning, it is often possible to reduce the impact of a charge or prevent it from arising unexpectedly.
Common strategies include:
Effective planning is about using allowances efficiently and understanding how contributions interact across different schemes, rather than reducing pension saving.
