More than two in five (44%) of 55- to 64-year-olds in the UK plan to move into semi-retirement before they reach 65, according to research conducted on behalf of Aviva. That means drawing on pension savings while continuing to work part-time, rather than stopping work altogether. For someone approaching State Pension age with a modest pension pot, the difference between full retirement and semi-retirement can be thousands of pounds of annual income — and it changes how much tax you pay, how long your savings last, and what benefits you can claim.

Semi-retirement sounds appealing — keep earning, keep a connection to work, but reclaim time for what matters. The data backs that up: 91% of people who reduced their hours said they were much happier. But the decision isn’t just about lifestyle. It touches pension access rules, tax relief, National Insurance contributions, and long-term savings adequacy. The version of semi-retirement that works for someone with a full defined benefit pension is very different from the one that works for someone relying on the State Pension and a small workplace pot.
Here’s what you actually need to know.
What Semi-Retirement Actually Means for Your Finances
Before going further, it helps to define what semi-retirement actually is. Unlike full retirement, where you stop paid work entirely, semi-retirement means reducing your hours, responsibilities, or income while still earning. You might draw from a pension to supplement your part-time earnings. The goal is a smoother transition, but the rules around pension access, tax, and National Insurance mean it’s not a simple case of “work less, take some pension, enjoy life.”
What I tend to notice is that people often assume semi-retirement is just a scaled-back version of full retirement. In practice, it sits in a more complicated zone — one where pensions, earnings, benefits, and tax interact in ways that can catch you out if you haven’t run the numbers.
The Pension and Income Rules That Shape Semi-Retirement
The numbers that matter most for semi-retirement are the ones that determine when you can access your pension, how much tax you pay on combined income, and what happens to your State Pension if you keep working. Each of these changes at specific age thresholds and income levels.
The table below shows how the main pension types interact with semi-retirement at different ages and income bands.

| Pension type | Minimum access age | Key rule for semi-retirement |
|---|---|---|
| Workplace defined contribution | 55 (57 from April 2028) | Can take 25% tax-free; remaining drawdown is taxable income alongside earnings |
| Workplace defined benefit (final salary) | Typically 60–65 | Reduced pension if taken early; transfer value may be an option but requires advice |
| Personal pension / SIPP | 55 (57 from April 2028) | Flexible drawdown or lump sums; MPAA triggers if you take more than the tax-free cash |
| State Pension | 66 (rising to 67 in 2028) | You can defer it while working and get a higher amount later; no tax on earnings if total income stays under Personal Allowance |
The most consequential number for most people is the Money Purchase Annual Allowance (MPAA). Once you start drawing taxable income from a defined contribution pension — anything beyond the 25% tax-free lump sum — your annual allowance for further pension contributions drops from £60,000 to just £10,000. That matters if you plan to keep earning in semi-retirement and want to keep building your pension. Miss that rule and you could face a tax charge.
On the State Pension side, deferring it while you work in semi-retirement can boost your weekly amount by roughly 5.8% for each year you delay (the exact rate is set by the government each year). For someone entitled to a full new State Pension of £221.20 per week (2025/26 rate), deferring for a year adds about £12.80 per week — or £665 per year — for life. That’s a material gain if your part-time earnings are enough to live on without the State Pension.
For a financial advisor, modelling the interaction between part-time earnings, pension drawdown, and State Pension deferral is a standard calculation. The numbers vary significantly depending on whether you’re in good health, how large your pension pot is, and whether you have other savings or a partner’s income to factor in.
Common Semi-Retirement Mistakes and the Cost of Getting Them Wrong
Starting pension drawdown before understanding the MPAA
This is the most financially damaging error. Taking a small taxable income from your pension — say, £5,000 a year to top up part-time earnings — triggers the MPAA and cuts your future contribution limit to £10,000. If you planned to keep adding to your pension while working part-time, that restriction can last for years. The fix is to plan withdrawals in order: take tax-free cash first, and only move to taxable drawdown once you’re confident you won’t need to make large pension contributions again.
Claiming State Pension too early while still earning
If you claim your State Pension at 66 while still earning part-time income, you pay tax on the combined total once it exceeds your Personal Allowance. For someone earning £10,000 from part-time work and receiving the full State Pension of £11,502 per year, the combined £21,502 is well above the tax-free threshold. Deferring the State Pension for a year or two could keep you under the tax band while building a higher guaranteed income for later.
Ignoring how semi-retirement affects means-tested benefits
Pension Credit, Housing Benefit, and Council Tax Support all depend on your income. Semi-retirement earnings and pension drawdown both count as income. If you’re close to the eligibility thresholds, even a small pension withdrawal could reduce or eliminate your entitlement. The pension pot panic article covers ways to check whether you’re leaving benefits unclaimed — a step worth doing before locking in a semi-retirement income plan.
Not checking your National Insurance record before reducing hours
Your State Pension amount is based on your NI qualifying years. If you drop below the earnings threshold for NI contributions (currently £123 per week from one employer, or £6,396 per year for employed work), you may stop building qualifying years. Missing a year reduces your State Pension by about 1/35th of the full amount — roughly £317 per year of retirement income, adjusted for inflation. If you’re self-employed and reduce hours, you may still need to pay Class 2 or Class 3 contributions to maintain your record.
How to Plan a Semi-Retirement That Works for Your Situation
Step 1: Map your income sources by age
Start with your State Pension age (currently 66, rising to 67 in 2028). Then map your private pension access age (55, rising to 57 in 2028). Between those two dates, you’ll rely on part-time earnings, any savings or investments, and potentially pension drawdown. The gap between 57 and 66 is the most financially sensitive period — you have the most options but also the most rules to navigate. A second-act career guide can help you think about what part-time work might look like in practical terms.
Step 2: Decide whether to take tax-free cash, drawdown, or both
The 25% tax-free lump sum from a defined contribution pension is the most flexible tool in semi-retirement. Take it first, and use it to supplement your earnings without triggering the MPAA. Once you move into taxable drawdown, you’re restricted. If you have multiple pension pots, you can take tax-free cash from one pot at a time, leaving others untouched. That preserves your options and keeps the MPAA at bay.
Step 3: Factor in the State Pension deferral decision
If your part-time earnings cover your basic costs, deferring the State Pension for a year or more adds a guaranteed, inflation-protected income stream for life. The trade-off is that you forego immediate income. The breakeven point is typically around 18 years — if you live longer than that, deferring pays off. For someone in good health with a family history of longevity, deferral is a strong bet.
Step 4: Review your tax position annually
In semi-retirement, your income can vary year to year. One year you might earn £15,000 from part-time work and take no pension. The next year you might earn £8,000 and take £10,000 from drawdown. Each combination has a different tax outcome. Running a quick calculation each April — or using a tax advisor — ensures you don’t accidentally push yourself into a higher tax band or trigger allowances you weren’t expecting.
What the future holds: rising State Pension age and changing pension rules
The State Pension age is already set to rise to 67 in 2028, and the government is reviewing whether it should go to 68 by the mid-2030s. The minimum private pension access age moves to 57 in April 2028, with a further rise to 58 possible in the 2040s. Anyone currently in their 40s or 50s planning semi-retirement should build in a buffer — the ages you’re targeting may shift before you get there. The advantage of semi-retirement over full retirement is that it gives you flexibility to adapt to these changes without a major disruption to your plans.

The Bottom Line on Semi-Retirement for UK Workers
The case for semi-retirement is strong — 44% of people in their late 50s and early 60s are already planning it, and the vast majority who try it report being happier. But the financial mechanics are not the same as full retirement. The MPAA, the rising pension access ages, the interaction between earnings and State Pension deferral, and the impact on means-tested benefits all need to be modelled before you commit to a plan. The biggest risk is not the decision itself — it’s making the decision without understanding which rules apply to your specific pension type, age, and income level.
