Tax in Early Retirement (UK): How to Pay Less Without an Adviser

I spent my whole career on PAYE, where tax more or less looked after itself. Planning to stop work at 58 forced me to actually understand it, and the biggest surprise was how little I'd owe in the early years if I was even slightly deliberate. Here's what I worked out for my own situation.

On a salary, the decisions were all made for me. The money arrived, it was taxed, the rest was mine. Stop work early and that flips. Pension draw-down, ISA withdrawals, the State Pension down the line, a bit of savings interest, and you're the one choosing how much comes from where, and when. Get it roughly right and the tax bill in the bridge years can be tiny. Get it wrong and you can hand over thousands you didn't need to. 

I'm not a financial adviser and this isn't personal advice. Tax turns on individual circumstances, and anything involved is worth paying a regulated professional for. What follows is simply what I worked through for myself, across the three situations I had to get my head around: a single early retiree, a couple who've both stopped, and the one I'm in, where one of you stops and the other keeps working. 

 

The foundations: the bits everything else rests on

Six things underpin all of it. 

• Personal allowance, £12,570. No income tax below this. Everyone gets it, every year, working or retired, and it's frozen at this level until at least April 2031. Above it, income up to £50,270 is taxed at 20%, then 40% up to £125,140, then 45% above. One trap worth knowing: between £100,000 and £125,140 the allowance is withdrawn gradually, which creates an effective 60% rate in that band. Few early retirees will be near it, but if draw-down plus rental or other income climbs that high, it needs managing. 
• ISA withdrawals, tax-free. Money out of an ISA, cash or stocks and shares, isn't income. It doesn't touch your personal allowance and doesn't interact with anything else. This is the single most useful feature of an ISA in retirement, and the reason building an ISA bridge before you stop is worth so much. Every pound you take from one costs nothing in tax and uses none of your allowance. 
• Pension draw-down, taxed as income. The 75% of a pension that isn't tax-free cash is taxed as income in the year you take it, added on top of everything else at your marginal rate. So how much you draw in any given year is one of the bigger levers you've got. 
• State Pension, taxable but rarely taxed on its own. It counts as taxable income. At £12,548 a year it sits just under the personal allowance. The catch is what it does once it starts: it swallows almost all of the allowance, so any draw-down on top is taxed from the first pound. That's exactly why the years before it arrives are the valuable ones. For me, stopping at 58 with the State Pension at 67, that's a nine-year window. 
• Personal savings allowance. £1,000 of savings interest tax-free at basic rate, £500 at higher rate. If your income drops in retirement and you move from higher to basic rate, this doubles. There's also a starting rate band: with low enough other income, up to £5,000 of savings interest can be taxed at 0%. Worth knowing if your draw-down is modest in the early years. 
• Capital gains tax, £3,000 a year. Gains on investments held outside an ISA or pension are tax-free up to £3,000 per person, £6,000 for a couple, then 18% at basic rate and 24% at higher. Useful if you're gradually feeding unwrapped investments into an ISA. 

 

Scenario 1: stopping before the State Pension (this one's mine) 

This is where the planning pays off most, and it's roughly my own position, so I'll use it rather than invent someone. 

I'm stopping at 58. My State Pension doesn't arrive until 67. I've a defined contribution pension, a Stocks and Shares ISA, some cash, and money from an inheritance sitting outside any wrapper. For those nine years nobody's paying me a salary, so my £12,570 allowance is doing nothing by default. 

What I worked out is this. If I live mainly off ISA withdrawals, which are tax-free and don't touch the allowance, I can top them up with pension draw-down of up to £12,570 a year and pay no income tax at all. There's a wrinkle I didn't grasp at first. If you take the pension as UFPLS, where a quarter of each withdrawal is tax-free cash and the rest counts as income, you can actually draw around £16,760 from the pension alone before any tax bites. The quarter comes out tax-free, and the remaining three-quarters lands inside the personal allowance. Add the savings allowance on top, and the CGT allowance if I'm moving unwrapped money across, and the realistic position is a comfortable income for the best part of a decade on a tax bill that rounds to almost nothing. 

What changes when the State Pension lands 

At 67 the picture shifts. The State Pension at £12,548 takes up nearly all of the allowance, and draw-down on top is taxed at 20% from the first pound. The lesson, which is shaping how I think about sequencing, is to use the allowance hard while it's free, lean on ISA withdrawals throughout, and not leave a large pension to draw down only after the State Pension has eaten the allowance. 

The sequencing, in plain terms

Before the State Pension: ISAs first, then pension draw-down up to the allowance, cash kept back for near-term security, and no large pension withdrawals that tip taxable income over the allowance without good reason. After it: the State Pension uses most of the allowance, ISAs stay free and keep doing the work, and pension draw-down above what's left of the allowance gets taxed at 20%. Spreading big withdrawals across tax years rather than taking them in one lump almost always means less tax over the whole of retirement. 

 

Scenario 2: both of you retired 

When both partners have stopped, it gets easier, because each of you has your own personal allowance, ISA allowance and CGT allowance. They don't merge. They stack. 

Two retired partners can each take £12,570 of taxable income with no tax, £25,140 between you, with tax-free ISA withdrawals on top. The commonest mistake is drawing everything from one person's pension while the other's allowance goes to waste. If one of you holds the big pot, the pull is to take it all from there, and the second allowance sits idle. Where both of you can access a pension, drawing up to £12,570 from each uses both allowances and leaves the household clearly better off. 

ISA allowances double too, £20,000 each, £40,000 between you, each person's withdrawals independently tax-free. If one ISA is much larger than the other, it can be worth moving investments between you over time to even them up. Transfers between spouses are free of CGT, and the receiving partner can then shelter them within their own ISA allowance in later years. The same no-gain-no-loss treatment on spousal transfers also gives you some say over who realises a gain and when. Once both State Pensions are in payment, at roughly £12,548 each, both allowances are largely used up, and the ISA becomes the one source that doesn't interfere with any of it. 

 

Scenario 3: one stops, one carries on (also mine, for now)

This is the fiddliest of the three and the most common among people stopping in their fifties. It's also my own household: I'm stopping shortly, my wife is self-employed and carrying on. I'll keep our specifics out of it, but the general mechanics are worth setting out. 

When one partner is still working, that partner is probably using most of their allowance through their income. The one who's stopped may have an allowance going partly or wholly unused, depending on what they draw. That unused allowance is the opportunity. The retired partner can draw pension income up to £12,570 with no tax, and if the working income already covers the bills, that draw-down can be redirected into an ISA or simply held rather than spent. It's household income arriving tax-free that wouldn't exist if you were both on salaries. 

A couple of smaller levers. Marriage allowance lets the lower earner pass £1,260 of unused allowance to the other, worth £252 a year, but only where the receiving partner is a basic-rate taxpayer. If they're over £50,270, it doesn't apply. And even a partner with no earnings can pay £3,600 gross into a pension each year, £2,880 of their own money plus £720 of tax relief, which quietly keeps a pot growing. The thing to watch in this set-up is the higher-rate threshold. If the working partner is near £50,270, an extra income source on their side can tip them over, so it pays to know where each of you sits. 

 

Income that isn't taxed

Quick reference for the tax-free sources that matter most to early retirees: 

• ISA withdrawals, no limit. 
• The 25% tax-free cash from a pension, subject to the £268,275 lump sum allowance. 
• Premium bond prizes, whatever the amount. 
• Interest and gains inside an ISA. 
• Gains inside a pension. 
• Gifts you receive (different inheritance tax rules apply to the person giving). 

 

The April 2027 inheritance tax change

One thing that's genuinely important and still not widely understood. From April 2027, unspent pension funds will generally fall into your estate for inheritance tax. Until now they sat outside it, which made a pension a quietly excellent way to pass money on. That advantage is going. It doesn't change how withdrawals are taxed while you're alive, but it does change the case for leaving a pension untouched, and it may change which pots you'd sensibly draw down first. If you've a meaningful pension and an estate to think about, it's worth talking through with an adviser before the date. It's on my own list to sort. 

 

The 2026/27 numbers, in one place

• Personal allowance: £12,570 - frozen until at least 2031. 
• Basic rate: 20% on income £12,571 to £50,270. 
• Higher rate: 40% on income £50,271 to £125,140. 
• Additional rate: 45% on income above £125,140. 
• Marriage allowance: £1,260 transfer — saves up to £252 per year. 
• ISA allowance: £20,000 per person per year. 
• CGT annual exempt amount: £3,000 per person. 
• Personal savings allowance: £1,000 basic rate / £500 higher rate. 
• Pension annual allowance: £60,000. 
• MPAA after taxable draw-down: £10,000 — permanent once triggered. 
• Tax-free cash lifetime cap: £268,275. 
• State Pension 2026/27: £12,548 per year. 

Tax rules move, so check the current figures at gov.uk before acting on any of them. 

 

Self-assessment: the admin nobody warns you about

Once you're drawing pension income and savings interest rather than a salary, you'll almost certainly need to register for self-assessment and file a return each year. HMRC doesn't automatically see draw-down from a personal or workplace pension. It's also how you reclaim the emergency tax that usually gets applied to a first pension withdrawal, and how you claim the marriage allowance. 

Registering is on my own to-do list for after my last day. The deadline is 5 October following the end of the tax year you start drawing taxable income, and from everything I've read the return itself is more straightforward than its reputation. I'll find out soon enough.

• Self-assessment registration and guidance. 
• For marriage allowance claims - you can apply online in minutes. 
• For the genuinely involved decisions, how draw-down, State Pension timing and ISA strategy interact across years, regulated independent advice earns its fee. The gap between a planned draw-down and an unplanned one can run to tens of thousands over a retirement.
