Tax saving tips for retirees

At a glance

• Good retirement tax planning is usually about coordinating multiple income sources, not chasing one “silver bullet”.
• Pension withdrawals can be part tax-free and part taxable. 
• The full new State Pension is £241.30 a week in 2026/27 and it is taxable. 
• ISAs can be a very useful way to top up retirement income without creating extra Income Tax. 
• Savings interest and dividends outside wrappers can still trigger tax in retirement. 

A practical guide to drawing retirement income tax-efficiently

One of the biggest surprises in retirement is that tax does not disappear when work stops. It simply changes shape. 

Instead of salary alone, you may now have a mix of State Pension, private pensions, ISA withdrawals, bank interest and dividends, all of which can interact in different ways when HMRC works out what you owe. 

The good news is that with a bit of planning, many retirees can reduce unnecessary tax. The key is usually taking the right money, in the right order, at the right time.

Who this guide is for

This guide is for retirees and people approaching retirement who want straight answers to the questions we hear most often: How are pension withdrawals taxed? How much tax-free cash can I take? When should I use my ISA? Will savings interest or dividends create a tax bill? It is especially relevant if your retirement income will come from more than one source. 

It is also useful for couples. In many cases, tax allowances are personal, so the way assets and income are split across a household can make a meaningful difference. 

8 tax-saving strategies that can make a real difference

1) Understand how pension withdrawals are taxed

Most modern defined contribution pensions let you take money flexibly, but not all of it is tax-free. In broad terms, you can usually take up to 25% of the amount built up in a pension tax-free, subject to the standard Lump Sum Allowance of £268,275. The taxable part of any withdrawal is added to your other income for that tax year. 

That means a large one off withdrawal can push you into a higher tax band very quickly. Retirement tax planning often starts with avoiding that trap. 

2) Treat the tax year as a planning tool

The tax year runs from 6 April to 5 April. For many retirees, it makes sense to spread withdrawals across more than one tax year rather than taking a large amount in one go. That can help you use your Personal Allowance more efficiently and avoid pushing more income into higher-rate tax than necessary. 

Sometimes the best tax saving is simply waiting until after 5 April. Read our end of year tax planning article for more detail.

3) Take tax-free cash in stages where possible

Many people assume they must take all their tax-free cash in one go. In reality, phased or partial drawdown can allow you to bring money out gradually. That can be helpful if you want flexibility and do not need the full lump sum immediately. 

Done sensibly, this can help you keep more of your withdrawals within lower tax bands over time. It also means some tax-free cash remains inside the pension (hopefully) growing inside a tax-free wrapper.

4) Use ISAs as your flexible top-up pot

For many retirees, ISAs are one of the most useful accounts to hold alongside pensions. 

Money inside an ISA grows free of UK Income Tax and Capital Gains Tax, and you are not taxed when you take the money out. GOV.UK. The ISA subscription limit is £20,000 in the 2025/26 tax year. 

In practical terms, that means if taking more pension income would tip you further into tax, using some ISA money instead can be a clean way to fund spending without increasing taxable income.

5) Check whether savings interest could become taxable

Cash savings can quietly create a tax issue in retirement, especially now that interest rates have been higher than many retirees were used to. 

Depending on your wider income, you may benefit from the starting rate for savings of up to £5,000, plus the Personal Savings Allowance of £1,000 for basic-rate taxpayers or £500 for higher-rate taxpayers. These allowances are set by HMRC and depend on your overall taxable income.

The catch is that these allowances depend on your other taxable income. A pension withdrawal that looks manageable on its own can also reduce or wipe out savings tax allowances.

6) Do not forget dividends outside ISAs and pensions

Dividend income is another area retirees often overlook, especially if they hold investment portfolios outside wrappers. 

In 2026/27 the dividend allowance is £500, and dividends above that are taxed according to your tax band. The government has also published higher dividend tax rates from 6 April 2026. GOV.UK.

So if you have shares or funds outside an ISA, your pension decisions can affect the tax paid on those dividends too.

7) Plan retirement income as a household, not just as individuals

Where appropriate, couples should look at retirement income together. Making use of two Personal Allowances, two ISA allowances and, in some cases, Marriage Allowance can reduce unnecessary tax across the household. Marriage Allowance can let a lower earner transfer £1,260 of Personal Allowance, reducing the recipient’s tax by up to £252. 

This will not suit everyone, but it is often worth reviewing who owns income producing assets and how withdrawals are split.

8) Watch for emergency tax on first withdrawals

A first flexible pension withdrawal is often taxed using an emergency basis, which can mean too much tax is deducted at source. HMRC provides in year reclaim routes, including forms P55 and P53Z, depending on the circumstances. 

This is not a reason to avoid drawdown. It is just something to expect and manage.

Common mistakes retirees make

Retirement tax issues are often caused by simple assumptions rather than complex rules. The most common ones we see are:

• taking one large pension lump sum without checking the wider tax effect 
• assuming the State Pension is tax-free because tax is not deducted from it directly 
• ignoring savings interest and dividends outside wrappers 
• drawing too much from pensions while leaving ISAs untouched when the reverse might be more tax-efficient 
• forgetting that HMRC may collect State Pension tax through another pension tax code or by Simple Assessment 

Worked example: pension only vs pension plus ISA

Assume Chris, age 67, receives the full new State Pension of £12,548 (2026/27) a year and needs £20,000 for home improvements. He has no other taxable income. This example uses the standard Personal Allowance of £12,570 and is rounded for simplicity.
