How are pensions taxed? 

Many people believe pensions are completely tax-free, however, they are actually ‘tax-deferred’. You are deferring tax today, to pay it later, usually when your income (and tax bill) is typically lower in retirement. 

Do you pay tax on your personal pension? 

Yes. Once you have taken your tax-free cash, any regular pension income or lump sums you withdraw from your private or workplace pension are usually treated as  income.

This is added to any other income you have (like the State Pension) and taxed at your standard Income Tax band i.e. 20%, 40%, or 45% for England and Wales (Scotland Tax Bands are different. 

‍

Do you pay tax on your State Pension? 

Yes, the State Pension is taxable income. However, the government will not deduct the tax from the State Pension payment itself. 

• The State Pension uses up part (or soon to be all) of your Personal Allowance of £12,570 that you can earn tax-free.
• If your total income (State Pension and private pot) exceeds the Personal Allowance, the tax is usually deducted from your private pension provider before they pay you.

Do you pay tax on pension contributions? 

No, you won’t pay tax on pension contributions. In fact, the opposite happens. You receive tax relief on contributions, meaning the money enters your pension free of Income Tax.

With tax relief, the government is technically ‘paying you back’ for the tax you already paid. 

Do you pay tax on your pension lump sum? 

Usually, the first 25% of your pension pot can be taken completely tax-free. The remaining 75% is taxed as income.

• It’s important to note if you take a single lump sum that includes both the tax-free and taxable parts, the taxable portion could push you into a higher tax bracket for that year, resulting in a large tax bill.

How does pension tax relief work? 

Pension tax relief is designed to refund the Income Tax you would have otherwise paid on your earnings. It acts as a government top-up to your retirement savings, boosting the amount that goes into your pot.

The "Net" vs. "Gross" Calculation

Tax relief is calculated as 20% of the "gross" contribution (the total amount in your pot after the top-up). This is equivalent to a 25% top-up on the "net" amount you pay in.

• Example: If you pay in £80 (your net contribution), the government adds £20 (25% of your payment). This totals £100 in your pension. That £20 represents exactly 20% of the final £100 gross total.

How tax relief is applied depends on the type of scheme you're in:

• Relief at source (most personal and some workplace pensions): You contribute from your take-home pay, and your provider automatically claims 20% basic rate relief from HMRC, adding it to your pot. If you're a higher or additional rate taxpayer, you claim the extra back through Self Assessment.
• Net pay (most workplace pensions): Your contributions are deducted from your salary before tax is calculated, so you automatically receive full relief at your marginal rate, no claiming required.

Taxpayer Brackets

• Basic rate taxpayers: You receive the automatic 25% top-up on your net contributions as shown above.
• Higher rate taxpayers: You can claim back an additional 20% through your Self-Assessment tax return. This means a £100 total contribution effectively costs you only £60 out of pocket.
• Additional rate taxpayers: You can claim back an additional 25%, meaning a £100 total contribution effectively costs you only £55.

This relief doesn't happen automatically, you need to claim it via a Self Assessment tax return. If you're a higher or additional rate taxpayer and haven't been doing this, you may be owed a significant rebate. 

Remember: If you are in a ‘net pay’ workplace scheme, this relief usually happens automatically before tax is deducted from your salary. Tax treatment depends on your individual circumstances and may be subject to change in the future.

The allowances

While the tax breaks are generous, they are not unlimited. If you save too much into a pension, or hold too much wealth, you hit the government's thresholds.

What is the pension annual allowance? 

The pension Annual Allowance is the threshold for how much you can save into your pensions each tax year while still receiving tax relief.

• The limit For the 2025/26 tax year is £60,000 (or 100% of your earnings, whichever is lower).
• This £60,000 limit includes your contributions, your employer's contributions, and the government's tax relief.

What is the tapered annual allowance? 

If you are a very high earner, your annual allowance threshold may be reduced (tapered) below £60,000.

Generally, this only applies if your ‘adjusted income’ (total taxable income and pension contributions) is over £260,000.

For every £2 your income goes over £260,000, your annual allowance is reduced by £1. The allowance can drop as low as £10,000 for the highest earners.

This only applies if your threshold income (total taxable income, excluding pension contributions) exceeds £200,000 and your adjusted income exceeds £260,000. 

What is the lump sum allowance? 

In April 2024, the government abolished the ‘Lifetime allowance’ (the cap on the total size of your pension pot). However, they kept a strict threshold on the tax-free cash you can take.

This is called the Lump Sum Allowance (LSA).

• The limit on the tax-free amount you can take over your lifetime is currently £268,275.
• You cannot take the excess tax-free if your 25% lump sum would exceed this amount, and this portion would be subject to Income Tax.

Pension funds

Once your money is inside the pension wrapper, it doesn't just sit there like cash in a bank account. It is put to work.

Your contributions are used to buy assets like shares in companies or government bonds, which are grouped together into a ‘fund’.

Understanding what this fund is, and whether you are in the right one for you, is one of the most significant factors in how much your pot will grow over time. Learn more about pension funds.
