Every April brings a fresh set of numbers that quietly reshape how much retirees actually take home. The 2026/27 tax year, which starts on 6 April 2026, is no exception. Between frozen tax thresholds, a rising state pension and upcoming changes to how pensions are treated for inheritance tax, there’s plenty for anyone already in retirement to think about.
Some of these shifts will affect your weekly income straight away. Others won’t bite until 2027, but they’ll reward those who plan ahead now. Let’s take a closer look at what’s changing and what you can do about it.
Frozen Allowances, Rising Incomes
The personal allowance stays fixed at £12,570 for yet another year. It’s been stuck at this level since April 2022, and the government has confirmed it won’t budge until at least April 2031. The higher-rate threshold remains at £50,270, and the additional-rate threshold holds at £125,140.
On the face of it, nothing has changed. But when your income rises and the thresholds don’t, you end up paying more tax without any official rate increase. This is what’s known as fiscal drag, and it hits retirees just as hard as workers. If your private pension, rental income or savings interest has grown even modestly, you could find yourself pushed into a higher tax band this year.
For retirees with income just above £100,000, the sting is sharper. Your personal allowance drops by £1 for every £2 earned above that mark, vanishing entirely at £125,140. That creates an effective 60% marginal tax rate on income between those two figures.
What the State Pension Rise Means for Your Tax Bill
Thanks to the triple lock, the full new state pension will rise by 4.8% from April 2026, going up from £230.25 to £241.30 per week. The full basic state pension (for those who reached pension age before April 2016) climbs from £176.45 to £184.90 per week.
That 4.8% uplift is welcome, of course. But here’s the catch. On an annualised basis, the full new state pension will come to roughly £12,537. That’s now within touching distance of the £12,570 personal allowance. If you have even a small private pension, savings interest or part-time earnings on top, you’ll be into taxable territory.
The government has confirmed that retirees whose only income is the full new state pension won’t have to pay income tax on it in 2026/27. But if you have any other source of income at all, HMRC will adjust your tax code on other payments to collect what’s owed. It’s worth checking your tax code early in the new year to make sure it’s correct.
How to Build a Tax-Efficient Withdrawal Strategy
If you’re drawing down from a pension pot, the order in which you take income from different sources will make a real difference to your tax bill. Getting specialist support with retirement planning for retirees can help you structure withdrawals so that you’re not paying more than you need to.
A common approach is to use your tax-free lump sum (up to 25% of your pension, capped at £268,275) first, then draw on ISA savings before tapping into taxable pension income. That way, you keep your taxable income as low as possible for as long as possible.
It also pays to spread withdrawals across tax years instead of taking large lump sums. A single big withdrawal could push you into the 40% bracket for that year, while smaller, regular drawdowns might keep you within the basic rate. For couples, coordinating withdrawals between two pension pots can make a significant difference, especially if one partner has unused personal allowance.
Pension Inheritance Tax Changes on the Horizon
One of the biggest shifts for retirees isn’t arriving until April 2027, but it’s already shaping planning decisions now. From 6 April 2027, unused pension funds and death benefits will be included in your estate for inheritance tax purposes. Until now, defined contribution pensions have sat outside the IHT net, making them one of the most tax-efficient ways to pass wealth to the next generation.
Under the new rules, your pension pot will be added to the value of your home, savings and other assets when calculating IHT. If the total exceeds the nil-rate band (£325,000, or up to £1 million for married couples passing on a qualifying home), your beneficiaries could face a 40% tax bill. For those who pass away after age 75, beneficiaries may also pay income tax when they withdraw the inherited funds, creating a combined tax rate that could exceed 60%.
This changes the long-standing advice to spend ISAs and savings first while preserving pension wealth. Some retirees may now benefit from drawing down pension income earlier and using it to fund gifts, top up ISAs or simply enjoy a better standard of living in retirement. Speaking to a financial planner before April 2027 will give you time to adjust your strategy.
Before You Go
The 2026/27 tax year doesn’t contain any single headline-grabbing change for retirees. Instead, it’s a collection of smaller shifts that add up. Frozen thresholds and a rising state pension will pull more pensioners into tax. Higher dividend rates will nibble at investment income. And the looming pension IHT changes in 2027 give everyone a reason to review how they’re drawing down their savings.
The retirees who’ll come out best are those who take a step back, look at their income as a whole and plan their withdrawals with tax efficiency in mind. If it’s been a while since you reviewed your financial plan, the start of a new tax year is as good a time as any.
The value of your investments and the income from them may go down as well as up, and you could get back less than you invested. Past performance should not be seen as an indication of future performance.
