Pension tax relief explained

Pensions are one of the most tax-efficient ways to save for your future, largely thanks to pension tax relief from HMRC. In this article, we'll explain everything you need to know about tax relief on pensions in simple, everyday terms.

Key takeaways

• Pension tax relief is a government top-up added to your pension contributions
• Basic rate relief is applied automatically
• Higher and additional rate relief must be claimed from HMRC
• You can claim up to four years back
• You can receive tax relief on up to £60,000 per year (or 100% of earnings)

What is pension tax relief?

You've probably heard that the main benefit of saving into a pension is tax relief. But what does that mean in real money terms?

The UK government wants to encourage you to save for life after work. They do this by offering a 'bonus' on contributions into your pension pot. This bonus comes from tax relief.

How does pension tax relief work?

Every time you pay into your pension, that money is exempt from tax. So if you're a basic rate taxpayer, adding £100 into your pot means you no longer owe the 20% basic rate income tax on that £100. This is true, even if you're self employed.

The government then 'refunds' this tax into your pension pot as a 'tax bonus'. So using the £100 example, you'll get £25 extra in your pot. Here's why.

You've already paid tax on the £100 you added to your pension. If you hadn't, your £100 would have been £125 - that's because £125 taxed at 20% is £100.

So, to make up the difference, the government refunds you £25 back into your pension. This is why you may see the pension tax bonus described as 25%. A 25% bonus on £100 is £25. £100 + £25 = £125.

Higher and additional rate taxpayers get to benefit from even more tax relief. Scroll down to check out how UK pension tax relief works for higher earners.

Tax relief on pension contributions is one of the main advantages of pensions when it comes to saving for the future.

Pension Tax Relief Examples

Here’s how pension tax relief works in real money terms for different taxpayers.

Basic rate taxpayer (20%)

• You pay: £80
• Government adds: £20
• Total in your pension: £100

This works because £100 before tax becomes £80 after 20% tax. Your pension provider claims the £20 back from HMRC and adds it to your pension automatically.

Higher rate taxpayer (40%)

• You pay: £60
• Government adds: £40
• Total in your pension: £100

Your pension provider automatically adds the first 20% (£20).You must claim the additional 20% (£20) back from HMRC through your tax return, by phone, or in writing.

Net result: £100 in your pension at a cost of £60.

Additional rate taxpayer (45%)

• You pay: £55
• Government adds: £45
• Total in your pension: £100

As with higher-rate relief, you must claim the additional tax relief directly from HMRC.

Net result: £100 in your pension at a cost of £55.

How do I claim pension tax relief?

Thankfully for most of us, claiming pension tax relief is easy.

When you pay into a private or personal pension, your provider will claim pension tax relief back on your behalf. As soon as your contribution has been processed and approved by the government, your tax bonus will be added to your pot automatically. This normally takes 2-3 months.

If you're contributing to a workplace pension scheme, the way tax relief is applied depends on the setup your employer uses. Some schemes use relief at source – where contributions are taken after tax, and your provider claims basic rate tax relief for you. Others use the net pay method – where contributions are taken before tax, giving you tax relief automatically.

If you're a higher or additional rate taxpayer, you may still need to claim extra relief via a self-assessment tax return, or by calling or writing to HMRC. Read on for more information on how that works.

How far back can I claim pension tax relief?

If you're thinking about claiming tax relief on pension contributions for previous years, you only have a limited time to do so.

You have four years from the tax year of the relevant pension contribution to let the government know you're owed tax relief on your payment.

Tax-free pension allowance

An important thing to bear in mind with pension tax relief is your pension tax limits. Everyone is entitled to tax relief on pension contributions up to the annual allowance threshold.

The pension tax allowance limits mean that you will only benefit from tax relief on a certain amount each tax year. The annual limit is:

• £60,000, or
• 100% of your earnings

You can still contribute to your pension above this amount - you just won't benefit from tax relief on any payments above this threshold. It's also worth knowing that you can carry over any unused allowance for up to three tax years.

Claiming higher rate tax relief on pension contributions

Basic rate pension tax relief is added to your pension automatically. However, if you’re a higher or additional rate taxpayer, part of your tax relief must be claimed directly from HMRC.

This is because most pension providers will only add the basic rate (20%) tax relief to your pension. Any extra relief you’re entitled to above this must be reclaimed separately.

Who needs to claim extra pension tax relief?

You will usually need to claim additional tax relief if:

• You pay 40% or 45% income tax
• Your pension uses a relief at source setup (most personal pensions and SIPPs)

If your workplace pension uses the net pay method, higher-rate relief is usually applied automatically through payroll, so no further claim is needed.

How to claim higher rate pension tax relief

You can claim your extra pension tax relief from HMRC in one of the following ways:

• By completing a self-assessment tax return
• By calling HMRC
• By writing to HMRC with details of your pension contributions

Once processed, the extra tax relief is usually paid:

• As a tax rebate, or
• By adjusting your tax code

How far back can higher rate tax relief be claimed?

You can usually claim back up to four tax years of unclaimed higher rate pension tax relief, as long as the contributions were eligible at the time they were made.
