The mid-course correction
This is the decade to stop guessing. Pull your pension statements together (the free government Pension Tracing Service finds lost pots), check your State Pension forecast, and run the whole picture through the retirement gap calculator. Twenty-plus years out, a shortfall is a to-do list; ten years out it's a crisis. The gap between those two sentences is your 40s.
Catch-up still works here
Adding £300/month at 45 puts roughly £110,000 more into a pot by 67 at 5% growth — and tax relief means it costs a higher-rate taxpayer nearer £180/month in take-home pay (run your own figures in the pension tax relief calculator). After a high-income year, carry forward lets you use up to three previous years' unused annual allowance — the standard tool for bonuses and business exits, detailed in the tax year-end checklist.
The cliff-edge check for peak earners
Between £60,000 and £125,000, UK tax has traps that turn pension contributions into outsized wins: the High Income Child Benefit Charge and the £100,000 personal-allowance taper (which also switches off childcare entitlements). Salary sacrifice or extra contributions can legitimately pull income back under a threshold — individual enough maths that a one-off session with an accountant or FCA-authorised adviser often pays for itself.
The competing demands, honestly ranked
- Your retirement outranks the children's university fund. Unsentimental but standard planning logic: loans exist for degrees, not for retirements. Fund your own future first, then help from strength.
- Mortgage overpaying vs investing is a real contest now. Rates, risk appetite and your remaining term decide it — model both sides in the overpay-vs-invest calculator, and diarise every fixed-rate expiry (see mortgages explained).
- Re-size the protection. Cover bought in your early 30s rarely matches a 40s life — bigger mortgage, more dependants, different salary. Rerun the logic in protection insurance, and check income protection especially: these are your highest-stakes earning years.
- Update the paperwork. Will, pension nominations, and — increasingly relevant — powers of attorney; all covered in wills and LPAs.
The conversation nobody schedules
Your 40s are when your parents' finances start to matter to yours: care needs, powers of attorney, and estates. A calm conversation now — do they have LPAs, a will, any plan for care costs? — prevents crisis decisions later. It's also the decade to understand inheritance tax basics from both directions.
