Retiring early is easy. Staying retired is the hard part. These are the tax, timing and State Pension traps that drain a pot faster than you planned.
You’ve done the sums. The pension pot looks healthy, the mortgage is nearly gone and the idea of handing in your notice at 58 no longer sounds daft. You might even have picked the date.
The trouble is that most early retirement plans don’t fail because the pot was too small on day one. They fail slowly, because of a few mistakes that add up over the next 30 years. Here are the ones to check for while you can still do something about them.
The first trap is assuming the money is there when you want it. At the moment you can usually take money from a private or workplace pension from age 55. From 6 April 2028 that normal minimum pension age goes up to 57. Some schemes have protected rights to an earlier age, but plenty don’t.
If you were born after 5 April 1973, plan on 57 unless your scheme confirms in writing that you can go earlier. Two extra years with no salary and no pension is a big gap to fill from savings.
The State Pension is further off. State Pension age is 66 and is moving up to 67 between 2026 and 2028, with a further rise to 68 already set in law for later. Retire at 57 and you could be living on your own money for a decade before the state pays anything. That bridge has to be paid for, and it is usually the most expensive part of the whole plan.
Not necessarily, and this is the trap people find out about too late. In the 2025/26 tax year the full new State Pension is £230.25 a week, about £11,973 a year. To get it you normally need 35 qualifying years of National Insurance. You need at least 10 to get anything.
Stop working at 55 with 30 years on your record and, unless something fills the gap, you’ll get roughly 30/35ths of the full amount. On 2025/26 rates that’s about £1,700 a year less, every year, for the rest of your life.
The fix is often cheap. Voluntary Class 3 contributions cost £17.75 a week in 2025/26, about £923 for a full year. A year’s contributions buys roughly £342 a year of extra State Pension, so you’d make the money back in under three years. Check your forecast on GOV.UK before you hand in your notice, not after. Some people get credits anyway, for example if they claim certain benefits or care for someone, so check before you pay.
Pension freedom comes with some small print. The first time you take taxable money flexibly from a defined contribution pot, the money purchase annual allowance kicks in. From then on you can only pay £10,000 a year into defined contribution pensions with tax relief, down from the normal £60,000 annual allowance. If you might go back to work, or do some consultancy and want to keep saving, that matters. Taking only your tax-free cash doesn’t trigger it.
That first withdrawal is also often taxed on an emergency code, so a big chunk gets taken off. You can claim it back from HMRC using the right form, or wait for it to be sorted out through the tax year, but in the meantime the money isn’t in your account.
Then there’s the bigger point. Taking a large lump sum in one tax year can push you into the higher or additional rate. If you spread withdrawals across years and make full use of your £12,570 personal allowance, you could pay a lot less tax on the same money. The personal allowance is frozen, so more of your income gets taxed as your pension rises. In Scotland the income tax bands and rates are different, so a Scottish taxpayer’s numbers won’t match those for England, Wales or Northern Ireland. Usually only 25% of a pension can come out tax-free, and for most people that’s capped at £268,275 in total.
The pot you retire with matters less than the order, timing and tax on the money you take out of it.
This is where bad luck with timing can do real damage. If markets fall just after you start drawing an income, you’re selling investments cheap to pay the bills. The money you sold is gone and won’t be there when prices recover. This is called sequence of returns risk.
Say you have £400,000 and plan to draw £20,000 a year. If markets drop 20% in year one, the pot is down to £320,000. Take out your £20,000 and you’re left with £300,000. To get back to where you started you now need a gain of a third, while still taking money out. Retire the year before a crash and your plan can look very different from the same plan started three years later.
People deal with this in different ways. Some keep a year or two of spending in cash so they don’t have to sell after a fall. Some cut withdrawals in bad years. Some use part of the pot to buy an annuity to cover the essentials. Each has trade-offs, and none is right for everyone.
Inflation does its damage more slowly. If prices rise 3% a year, the £30,000 you need today will be about £40,300 in ten years. A plan that ignores that will look fine at first and start to fall short in your late sixties.
Most retirement spreadsheets quietly stop at 85. Real life often doesn’t. A healthy man retiring in his late fifties has a reasonable chance of reaching his nineties, and the ONS life expectancy calculator will show you the odds for your age. Running out of money at 88 is a worse result than leaving some behind.
Then there’s inheritance tax. From 6 April 2027 most unused pension pots are set to count as part of your estate for inheritance tax. For years the standard advice was to spend ISAs and other savings first and leave the pension until last, because it passed on outside your estate. That plan needs looking at again. If yours relied on it, check it now.
Finally, don’t forget the costs that arrive all at once: a new car, a new roof, helping the children with a deposit, or care later in life. Treat these as lumpy one-off expenses, separate from your normal monthly spending. If they’re hidden inside a monthly average, you’ll underestimate them.
None of this means you shouldn’t stop work early. It means you should test the plan before you rely on it. Pension Wise offers free, impartial guidance from age 50 on your defined contribution options, and MoneyHelper covers the rest. For a decision this big and this personal, paying an FCA-regulated financial adviser for a proper cash-flow plan is often worth it.
Early retirement plans usually go wrong because of timing and tax, not because the pot was too small. Check when you can actually get your money (57 for many people from April 2028), fill any gaps in your State Pension record, watch the money purchase annual allowance and emergency tax on your first withdrawal, and plan for a market crash, inflation and a long life. Get free guidance from Pension Wise or advice from an FCA-regulated adviser before you hand in your notice.
You don’t need to sell the car and live on lentils to fix your pension after 50. These are the dull but effective levers that really make the difference, with real numbers.
Taking pension cash in your fifties sounds great until HMRC shows up. Here’s how the access age, tax-free lump sum and 40% or 45% tax can shrink your retirement.
Keeping everything in cash can feel prudent. Investing everything can feel bold. Neither is a plan. Give each pound a job based on when you will need it.
A financial shock in your fifties can unsettle your retirement plans. Here is how to work out the cash you need without treating your pension as a spare current account.
