A defined contribution pension scheme works by building a personal investment pot from three income streams: your contributions, your employer’s contributions, and government tax relief. That pot is invested in funds, grows or falls with the markets, and whatever is left at retirement is yours to draw on. Unlike a defined benefit (final salary) pension, which promises a specific income based on your salary and years of service, a defined contribution scheme puts the investment risk and the reward on you. Most workplace pensions set up today are defined contribution schemes, largely because UK law now requires employers to automatically enrol eligible workers into one.
How You Join and What Goes In
Since 2012, UK employers have had to enrol qualifying workers into a workplace pension. You qualify as an “eligible jobholder” if you are aged between 22 and state pension age, work in the UK, and earn above the auto-enrolment trigger of £10,000 per year for the 2026/27 tax year.1The Pensions Regulator. Employer Duties and Defining the Workforce If you meet those criteria, your employer must enrol you and start paying in. You can opt out, but your employer is required to re-enrol you roughly every three years.
The minimum total contribution is 8% of your qualifying earnings, split between your employer (at least 3%) and you (at least 5%). Qualifying earnings are the slice of your pay between £6,240 and £50,270 for 2026/27.2The Pensions Regulator. Earnings Thresholds Many employers pay more than the 3% minimum, so check your scheme details before deciding how much extra to put in yourself.
Tax Relief: Two Methods
Money also arrives from HMRC in the form of tax relief, and how you receive it depends on which arrangement your scheme uses.
Under relief at source, your contribution comes out of pay after tax. The provider then claims basic-rate relief (20%) from HMRC and adds it to your pot. Pay in £80 of take-home money and the provider tops it up to £100.3GOV.UK. Reclaim Tax Relief for Pension Scheme Members With Relief at Source Higher-rate and additional-rate taxpayers can claim the extra relief through Self Assessment.
Under a net pay arrangement, your employer takes the contribution from gross pay before income tax is calculated. You automatically get relief at your full marginal rate, with nothing to claim back. The downside is that if you earn below the personal allowance and pay no income tax, you get no relief. HMRC has introduced a top-up for low earners caught by this.4GOV.UK.

How Much You Can Pay In With Tax Relief
There is a cap on tax-relieved contributions. For 2025/26, the annual allowance is £60,000. Pay in more and you trigger an annual allowance charge that effectively claws back the tax relief on the excess. You settle it through Self Assessment, or you can ask your scheme to pay it from your benefits.
If you did not use the full £60,000 in any of the previous three tax years, you can carry the unused portion forward and add it to this year.5GOV.UK. PTM055100 – Annual Allowance: Carry Forward: General This matters in bonus years or when making a large one-off top-up. You must have been a member of a registered pension scheme in each of the years you are carrying forward from.
The Money Purchase Annual Allowance
Once you flexibly access your pot, through drawdown or an uncrystallised funds pension lump sum, the allowance for further money purchase contributions drops to £10,000.6GOV.UK. Pension Schemes Rates This is the money purchase annual allowance (MPAA), and it catches people who dip in while still working. Carry forward cannot be used to top it up, so an early flexible withdrawal has a lasting cost for future tax-relieved saving.
How the Pot Is Invested
Contributions are invested in funds holding a mix of shares, government bonds, corporate bonds, and other assets. Most members sit in the scheme’s default fund, which takes more risk when retirement is far away and gradually shifts toward lower-risk investments as your target retirement date approaches. You can usually override the default and pick from a range of funds if you want a specific asset class or risk level.
Because the pot is in the market, its value moves daily. Over long periods, equities have historically outpaced inflation, but there is no guarantee and short-term losses are routine. Nobody promises you a figure at retirement. Your final pot is whatever contributions and returns have produced, minus the provider’s fees. Those fees matter: small differences in the annual management charge compound heavily over 30 or 40 years.
When and How You Can Take the Money
You can normally start taking money from a defined contribution pension at age 55. The minimum age rises to 57 on 6 April 2028.7GOV.UK. Increasing Normal Minimum Pension Age You do not have to stop working or leave your employer first. Three main options exist, and you can combine them.
Uncrystallised Funds Pension Lump Sum
An uncrystallised funds pension lump sum (UFPLS) lets you take cash straight from the pot, either in one go or in instalments. Each payment is 25% tax-free and 75% taxed as income. It suits a specific need for a specific sum, but every UFPLS triggers the MPAA.
Flexi-Access Drawdown
Flexi-access drawdown moves some or all of your pot into a drawdown fund that stays invested while you take income from it.8GOV.UK. Personal Pensions: How You Can Take Your Pension You can usually take up to 25% of the amount you designate for drawdown as a tax-free lump sum upfront, and later withdrawals from that fund are taxed as income. You keep control of timing and amounts, and the remaining pot continues to rise or fall with the market. The risk is that poor returns or heavy withdrawals could empty the pot during your lifetime.
Buying an Annuity
An annuity converts some or all of the pot into a guaranteed income for life, paid by an insurance company. Once bought, the income is locked in. You give up access to that money in exchange for payments that will not stop, whatever happens to markets or how long you live. Rates vary between providers and depend on interest rates at the time of purchase, your age, and your health. Shopping around through the open market option is essential; the rate your existing provider offers is rarely the best.
Tax on What You Take Out
Up to 25% of your pot can be taken tax-free, subject to an overall cap of £268,275.9GOV.UK. Tax When You Get a Pension: What’s Tax-Free Everything above the tax-free portion is taxed as income at your marginal rate, alongside any other income you have that year.10GOV.UK. Income Tax Rates and Personal Allowances
Your provider deducts tax before paying you, but the code applied is often wrong in the first year of withdrawals or when you have other income. A large one-off payment can push you into a higher band for that tax year, and emergency codes commonly produce overpayments you then reclaim from HMRC. Spreading withdrawals across tax years is the simplest way to keep more of the money.
What Happens to the Pot When You Die
Defined contribution pensions do not automatically fall into your estate. The scheme trustees decide who gets the remaining pot, guided by the expression of wish form you lodge with your provider. That discretionary structure is what keeps the funds out of probate and, for now, out of inheritance tax.
If you die before 75, beneficiaries can normally receive the pot free of income tax, provided they claim within two years of the scheme learning of your death.11MoneyHelper. What Happens to My Pension When I Die? Die at 75 or older and anything they draw is taxed at their own marginal rate. They can take it as a lump sum, move it into drawdown, or buy an annuity.
From April 2027, unused pension funds and death benefits may be counted as part of your estate for inheritance tax.11MoneyHelper. What Happens to My Pension When I Die? The full detail is still being finalised, but the direction is clear: pensions are losing their uniquely favourable inheritance tax treatment. If you have a large pot and estate planning concerns, revisit your strategy well before that date.
