How the contribution tiers work
Unlike Income Tax, which only taxes the portion of your pay above each band, your NHS Pension contribution tier applies to your whole pensionable pay, not just the amount above the tier threshold. Moving up a tier, for example after a pay rise, increases the rate on all of your pay, not only the part above the boundary.
| Pensionable pay (whole-time equivalent) | Contribution rate |
|---|---|
| Up to £13,259 | 5.2% |
| £13,259 to £28,854 | 6.5% |
| £28,854 to £35,155 | 8.3% |
| £35,155 to £52,778 | 9.8% |
| £52,778 to £67,668 | 10.7% |
| Above £67,668 | 12.5% |
For example, someone on £32,000 of pensionable pay falls into the 8.3% tier, so their contribution for the year is £2,656. Scotland, Wales and Northern Ireland can set their own tier boundaries and effective dates rather than automatically following England's, so check your own payslip or Trust/Health Board if you're not in England.
Why it's deducted before tax
The NHS Pension Scheme is a "net pay" arrangement: your contribution comes off your pensionable pay before Income Tax (and student loan repayments, if you have one) are calculated, but after National Insurance, which is still worked out on your pay before the pension deduction. That means you get tax relief automatically at your full marginal rate, with nothing to claim yourself - see the pension tax relief explained guide for how this compares with relief-at-source personal pensions, where higher-rate staff do have to claim extra relief themselves.
It's a defined benefit pension, not a pot you build up
For almost all current members, that's the 2015 Scheme, a career average revalued earnings (CARE) design. Each scheme year, you build up a slice of pension worth 1/54th of that year's pensionable pay, added to a running total that's then revalued every year in line with inflation (CPI plus 1.5%) until you retire. For the £32,000 example above, that's roughly £593 of annual pension added for that one year. This is a fundamentally different design from a typical workplace defined contribution pension, where your eventual income depends on how a pot of invested money performs; here, what you'll receive is set by a formula, not by investment returns.
How it interacts with the Annual Allowance
Your NHS Pension still counts towards the standard £60,000 pension Annual Allowance, but because it's defined benefit, what counts isn't your contribution - it's the growth in the value of your pension over the year, calculated using a formula set out on your annual Pension Savings Statement from NHS Pensions, not anything visible on your payslip. This mainly affects high earners or staff with a large jump in pensionable pay in one year (a promotion, or a lot of extra shifts). The pension carry forward calculator covers how tapering and unused allowance from previous years work if this applies to you.
The employer contribution most staff never see
On top of your own contribution, the NHS pays in a separate employer contribution, currently 23.7% of your pensionable pay, which never appears as a deduction on your payslip. For the £32,000 example, that's a further £7,584 a year the NHS is putting toward your pension on top of your own contribution. It's a substantial part of the overall value of working for the NHS, and it's simply lost, not paid to you some other way, if you opt out.
This is a general explainer of how the scheme works, not personalised financial advice. The NHS pay calculator shows your own pension deduction alongside Income Tax and National Insurance for your actual band and pay point.
