If you work in the NHS, your pension is one of the best available in the UK. However, NHS pension tax can leave doctors and dentists across the UK with charges they may not expect.
Every year, thousands in the medical field find out too late that their generous pension growth has pushed them over the annual allowance from the government, which then triggers an unexpected tax charge.
At Tax Driven Accountants, we help doctors and dentists make sense of their NHS pension tax position and advise on how to effectively work with HMRC to stay compliant. Find out everything you need to know in this guide.

How does NHS pension tax work?
Every year, your NHS pension grows through a combination of:
- Your salary
- Service
- (for dentists) pensionable earnings.
The growth of your pension is measured against a limit known as your annual allowance. If your pension growth within a single tax year has reached higher than that allowance, the excess will then be taxed at your marginal rate, potentially 40-45%, as if it were extra income.
What is the NHS pension annual allowance?
For most people in the UK, the annual allowance currently sits at £60,000 per year. This represents the maximum amount a pension can grow by, while still receiving the full tax relief from the government.
While it appears generous, the NHS pension growth is calculated differently to a typical workplace pension, as it’s based on the increase in value of your future pension income, instead of what you or your employer pays in. For doctors and dentists with several years of NHS service, this potentially produces a larger growth figure than what may be expected from a payslip.
Why NHS professionals often face a pension tax charge
Medical professionals such as consultants, GPs, and dentists are particularly likely to be affected by NHS pension tax because:
- Pay progression and clinical excellence awards can cause a significant increase in pensionable pay for a single year
- Dentists’ pensionable earnings can fluctuate from one year to the next, depending on NHS contract activity
- Having a long period of NHS service means each year of growth is calculated on an existing and substantial pension total.
This doesn’t mean you’ve done anything wrong in building your pension over your time of employment. What it does mean, is that the allowance needs to be checked every year, as opposed to when you receive and increase in income, and it would be best to ask a professional for advice if you’re uncertain.
NHS pension tax and the tapered annual allowance
For higher earners in the NHS, your pension tax position can be affected by the tapered annual allowance.
This allowance applies if your threshold income rises above £200,000 and your adjusted income is above £260,000. This means, for every £2 your adjusted income exceeds that limit, annual allowance drops by £1, to a minimum of £10,000. Many senior consultants find themselves close to these thresholds, so we’d recommend checking this each year.
Pension saving statements
If NHS pensions believe you’ve exceeded your annual allowance and may owe tax to HMRC in a given year, you’ll receive a pension savings statement, which shows pension growth.
Check this question thoroughly for variances which could cause you issues, and to make sure the figures align correctly. For those who haven’t received a pension savings statement, you can request one directly from the NHS.
How to reduce your pension tax bill through carry forward and Scheme Pays
You may not need to pay your NHS pension tax charge in full, as carry forward allows you to use any unused annual allowance from the previous three tax years to offset the excess.
If a charge is still due after carrying forward, and it’s over £2,000, you can often request the NHS Pension Scheme to pay it on your behalf through Scheme Pays. This will have the amount deducted from your pension at retirement instead of paid upfront.
Do you need to report NHS pension tax through Self Assessment?
NHS pension tax isn’t resolved automatically, and needs to be reported through Self Assessment, along with the relevant pension input details.
Missing this, or reporting it incorrectly, can lead to penalties and interest, on top of the tax. This is one of the most common areas we see mistakes, often because of the pension figures not being straightforward to interpret.

How does pension tax work for dentists?
Dentists sit in a slightly different position to salaried NHS staff when it comes to NHS pension tax.
It depends on how you work as a dentist in the UK, as NHS pensionable earnings can alter based on how you work, and how they interact with your tax position. This changes if you’re:
- A performer
- An associate
- Through a limited company.
This type of fluctuation in NHS contract income makes annual allowance calculations more difficult to predict from year to year, and many dentists only discover an issue once the pension savings statement arrives.
This means that because dentistry often involves a mix of NHS and private income, getting a clear, joined-up view of your tax position is essential to avoid any errors.

Find the answers to NHS pension tax questions
Alongside this guide, we also wanted to share the answers to commonly asked questions regarding pensions in the UK.
Do I pay 40% tax on my pension?
Not on the pension itself, but if your pension growth exceeds your annual allowance, the excess is taxed at your marginal rate, which could be 40% or 45% depending on your income.
How much of my NHS pension can I take tax-free?
Most NHS Pension Scheme members can take a tax-free lump sum, usually up to 25% of the capital value of their pension. This is subject to HMRC limitations.
How do I calculate my NHS pension annual allowance?
It’s based on the growth in the value of your NHS pension over the tax year, instead of the contributions you make into your pension. NHS Pensions issues a pension savings statement showing this figure if you’re likely to be affected.
Why am I paying tax on my pension when I haven’t changed jobs?
Pay progression, awards, or how NHS pension growth is calculated each year can push you over the allowance even without a change in job position or role.
How does the NHS Pension Scheme work for dentists?
A dentists’ pensionable earnings are based on NHS contract activity, which can vary year to year, making annual allowance calculations less predictable than for salaried staff.
