NHS Pension If You Incorporate: The Dentist's Rule

If you're a dental associate or locum thinking about working through a limited company, there's one rule you have to get straight before anything else: a performer who works via a company cannot pension their NHS income. The tax savings can look attractive on paper, but for many associates the NHS pension is the single biggest reason to think twice.

This isn't a grey area or a planning opinion. It's how the NHS Pension Scheme Regulations are written, and it has been the position since 7 November 2011. Get it wrong and you can spend years building a tax structure that quietly switches off one of the best pensions in the country.

This guide is for associate and locum dentists weighing up incorporation. It explains exactly what happens to your NHS pension, why providers (practice owners) are treated differently, and what the decision really costs. We'll keep it tightly focused on the pension consequence, then point you to the wider sole trader versus company question.

In short: what happens to your NHS pension when you incorporate?

If you're a performer (an associate or locum) and you work through a limited company, you cannot pension your NHS general dental services income through that arrangement. Practice owners who are providers can incorporate and remain in the scheme, because they hold the NHS contract directly.

Why can't an associate pension NHS income through a company?

The NHS Pension Scheme is open to individuals, not companies. A dental performer has to perform the work as a person to pension their NHS general dental services (GDS) or personal dental services (PDS) income.

When an associate incorporates, the picture changes. The practice (the contractor) no longer engages you directly. Instead it sub-contracts with your company, and your company sends you in to do the work. Under the NHS Pension Scheme Regulations that company isn't recognised as a type 1 dental practitioner, so the income flowing through it can't be pensioned.

The NHS Business Services Authority (NHSBSA) sets this out plainly: a dental practitioner or performer who has set themselves up as a limited company cannot contribute to the NHS Pension Scheme, and this has applied since 7 November 2011. If you incorporated before that date and your limited status is later confirmed, any membership from 7 November 2011 onwards is refunded.

So the moment your NHS work runs through your company, the pension door closes on that income. It's not reduced or restricted. It stops.

What's the difference between a provider and a performer?

This distinction is the whole ballgame, so it's worth being precise.

A provider holds the NHS contract. In a typical practice that's the owner, or the owners, who signed the GDS or PDS agreement with the local commissioner. In NHS pension terms these are type 1 dental practitioners.

A performer does the clinical work but doesn't hold the contract. Associates and locums are performers. In NHS pension terms an associate is a type 2 dental practitioner.

Here's the table that matters most when you're deciding whether to incorporate.

The role you hold, not the label on your headed paper, decides which row you're in.

Why can practice owners stay in the scheme but associates can't?

A practice owner who incorporates is still the person who holds the NHS contract through their company structure. The NHSBSA confirms that a GDS or PDS contractor can incorporate, and the providers (the general dental practitioner shareholders) can remain in the NHS Pension Scheme.

The reason is the contract. Providers are pensioned on the profit they draw from the NHS contract they hold. That link survives incorporation because they're still the contract holders.

An associate has no NHS contract. The associate's pension depends entirely on being engaged as an individual performer. Put a company in the middle and that direct individual engagement is gone, and with it the route into the scheme.

This is why two dentists in the same building can reach opposite answers. The owner can incorporate and keep pensioning NHS work. The associate down the corridor cannot.

What does losing the NHS pension actually cost? (Illustrative example)

It helps to see the trade-off in numbers. The NHS pension is a defined benefit (career average) scheme, so the value isn't the contribution you put in, it's the guaranteed, inflation-linked income it builds. That's hard to replace with a personal pension.

Illustrative example. Maya is an associate with around £80,000 of net pensionable NHS earnings a year. She's deciding whether to incorporate.

• As a self-employed associate she stays a type 2 practitioner and keeps building NHS pension on those earnings every year she works.
• If she incorporates and runs her NHS work through a company, that £80,000 of NHS income stops being pensionable from the date of incorporation. The benefits she has already earned are safe, but she stops adding to them.
• To match a defined benefit, inflation-linked pension privately, she would need to fund and invest a personal pension herself, with no guarantee on the eventual income and no employer-style contribution behind it.

The point isn't a precise figure, because everyone's pensionable earnings and career length differ. The point is the shape of the loss: you trade a guaranteed, index-linked NHS pension on your NHS earnings for whatever you can build yourself. For an associate doing significant NHS work, that's usually the deciding factor against incorporating the NHS side.

Private and purely cosmetic work is a separate matter, and that income was never in the NHS scheme to begin with, so incorporating private work doesn't carry this particular cost.

How do associate pensions normally work, and how is the contribution declared?

If you stay self-employed, here's the machinery, so you can see what incorporation would switch off.

Your NHS pensionable pay is your net pensionable earnings: broadly your share of the practice's NHS contract value after agreed expenses, settled between you and the provider. Because the practice's full-year NHS position isn't known until the year ends, your contributions are reconciled after year end.

Each year, after the Annual Reconciliation Report (ARR) is completed on the NHSBSA's Compass system, you get an SD86C, your Annual Pensionable Earnings and Contribution Statement. The ARR process runs to around the end of July, with the SD86C typically available on Compass from early August. Your accountant uses that SD86C to confirm the superannuation figures in your accounts and tax return.

Run your NHS work through a company and none of this applies to that income, because there's nothing pensionable to reconcile.

Is the superannuation contribution tax deductible?

Yes, while you remain a self-employed practitioner. This is another piece of value that disappears with incorporation.

HMRC's Business Income Manual at BIM54020 confirms that a self-employed dental practitioner pays both the employee contribution and the employer's contribution to the NHS Pension Scheme, and that for tax purposes both elements are relievable as member contributions in computing trading profits. That treatment has applied since April 2006.

BIM54020 also notes that these NHS superannuation contributions are disregarded when working out whether you've exceeded the annual allowance, and can be excluded when calculating threshold income for the tapered annual allowance, unless they were made under a salary sacrifice arrangement entered into on or after 9 July 2015.

So as a self-employed associate you get a real, allowable deduction for your superannuation. Incorporate your NHS work and there's no NHS contribution to deduct, because there's no NHS pension contribution to make.

What about the annual allowance, Scheme Pays and McCloud?

If you stay in the scheme, three things are worth knowing. They don't change the incorporation rule, but they shape the value of staying in.

The annual allowance. For 2025/26 the standard annual allowance is £60,000. It can taper for high earners: it reduces by £1 for every £2 of adjusted income over £260,000, down to a minimum of £10,000, and only bites where threshold income is also over £200,000. For NHS defined benefit pensions the figure that counts against the allowance is the growth in your pension value, not the cash you pay in, which is why high-earning dentists can face an annual allowance charge in a strong growth year.

Scheme Pays. If you have an annual allowance charge, you can ask the NHS Pension Scheme to pay some or all of it to HMRC on your behalf in exchange for a reduction in your benefits. The standard deadline for a voluntary Scheme Pays election is 31 July in the year following the relevant Self Assessment deadline.

McCloud. To remove age discrimination, pensionable service for the remedy period of 1 April 2015 to 31 March 2022 has been rolled back into the 1995/2008 scheme. That rollback can change earlier annual allowance positions, and HMRC has a digital service that lets affected members reassess annual allowance charges and, where due, claim a refund or compensation.

All three are reasons the NHS pension is worth protecting. None of them is available on NHS income you've routed through a company, because that income isn't in the scheme.

What's changed for associate self-employed status since 2023?

There's a related change worth flagging, because it interacts with how associates are taxed.

Until recently, HMRC operated a long-standing concession (set out in its Employment Status Manual at ESM4030) that treated associate dentists on a standard BDA or DPA-style agreement as self-employed for tax purposes. That concession was withdrawn from 6 April 2023.

Associate self-employment now rests on the ordinary employment status tests, the same factors HMRC applies to anyone, supported by its Check Employment Status for Tax (CEST) tool. In practice most genuine associate arrangements remain self-employed, but the status is no longer automatic and the agreement and working reality both matter.

This doesn't change the incorporation rule. It's a reason to make sure your status and contracts are sound before you start restructuring anything.

A decision walkthrough before you incorporate

Here's the order we'd think it through with an associate or locum client.

1. What's your role? If you're a provider (you hold the NHS contract), you can incorporate and stay in the scheme as a provider. If you're a performer (associate or locum), NHS income through a company isn't pensionable. This is the first fork in the road.
2. How much of your income is NHS? The more of your earnings that are NHS and pensionable, the more an NHS associate stands to lose by incorporating that work. Heavily private or cosmetic associates lose less here, because that income was never pensionable anyway.
3. What would replacing the pension cost? Be honest about funding a private pension to stand in for a guaranteed, inflation-linked NHS benefit. That replacement cost belongs in any comparison with the corporation tax and dividend savings.
4. Is your self-employed status solid? With the ESM4030 concession gone since April 2023, confirm your status holds before you build a structure on top of it.
5. Could you split private and NHS work? Some dentists keep NHS work as an individual to protect the pension and consider a company only for clearly separate private work. Whether that's appropriate depends on your contracts and the commercial reality, and it needs proper advice.

That's the pension-focused view. The full incorporation decision also covers corporation tax, dividends, salary, pensions other than the NHS scheme, and admin. We've covered the wider picture in our guide to choosing between a dentist limited company and sole trader, and you can read more about how we support associates on our associate dentist accounting page.

This is a high-stakes, easy-to-get-wrong area, so it's worth a proper conversation before you act. If you want a second opinion on the numbers and the pension trade-off, our tax advisory team can model it with you.
