How much can a dental associate typically save by switching to a specialist accountant?

Varies. The most common single saving is missed expenses on indemnity, CPD, and motor on a sole-trader return where the previous accountant was conservative. We have seen four-figure refunds on amended returns where the previous claims were under-stated. Switching is rarely about saving £X this year specifically; it is about not leaking that £X every year going forward.

Do I need to incorporate as an associate?

Usually not. Incorporation only typically benefits associates earning above roughly £80,000–£100,000 sustainably, and even then the NHS Pension Scheme interaction can change the answer. We model your specific numbers before recommending the structure.

What about IR35 if I work through a limited company?

Since 6 April 2021, when the engaging practice is a medium or large client (most are), the practice determines your IR35 status, not your PSC. If a practice tells you the engagement is inside IR35, you pay PAYE-style deductions despite the company structure. We will look at the determinations across your practices and model the realistic post-tax outcome before any structural decision.

Can I claim my dental school student loan interest as an expense?

No. Student loan repayments are not an allowable trade expense. They are a separate deduction taken through the self-assessment based on income level and student loan plan. Plan 2 and Plan 5 repayment thresholds differ; we apply the correct plan on your return.

Associate & locum tax

Tax support for dental associates and locums

Associate dentist tax looks simple until it isn't. Self-employment status, expense claims, the NHS Pension interaction, indemnity treatment, IR35 risk for limited-company locums on NHS contracts. We see all of it weekly and structure your return so you keep what you are entitled to keep, without picking a fight you would lose with HMRC.

Self-employment status: still the right answer for most associates, but no longer automatic

Most dental associates are self-employed, work under a BDA-style model agreement, file self-assessment and claim expenses. That is the right shape for the majority of associate engagements.

But HMRC and the tribunals have made clear that the paperwork alone does not determine status. They test the actual working arrangement against five factors: control, substitution, mutuality of obligation, financial risk, integration into the practice. If your day-to-day working arrangement looks like employment (fixed hours, no realistic substitution, practice-supplied materials, practice equipment, no real downside risk), the BDA model contract on file will not save you.

We review the working arrangement, not just the contract, and flag where status risk sits.

Allowable expenses an associate should be claiming

The genuine commercial expenses an associate incurs are deductible in the self-assessment return. Most associates we onboard are claiming roughly half of what they should be.

Indemnity insurance (Dental Protection, MDU, MDDUS) — fully allowable trade expense
GDC retention fee and any specialist register fees
CPD courses, online and in-person, where genuinely relevant to your clinical practice
Professional subscriptions to BDA, college memberships, specialty associations
Loupes, magnification equipment, instruments where you have purchased your own
Motor expenses for travel between practices (not home-to-first-practice; that is commute)
Phone and internet apportioned to clinical use (a sensible percentage, documented)
Accountancy fees and professional advice fees

Locum dentists working through a limited company

Limited-company locums working on NHS engagements have to confront the post-April-2021 IR35 rules: when the engaging practice is a medium or large client, the practice (not the locum's PSC) determines IR35 status. Inside-IR35 means PAYE-style deductions despite the company structure.

We model umbrella vs limited-company vs sole-trader for a locum dentist's specific income mix and engagement type. There is no single right answer; the right answer depends on the practices you work at, how they classify status, and how much of your work falls inside vs outside IR35.

NHS Pension scheme: still valuable, but watch the annual allowance

Many associates default into the NHS Pension Scheme and stay there without reviewing. The default is usually right — the scheme remains one of the most valuable in the UK. But high-earning principals and high-earning associates with significant private income on top can hit the tapered annual allowance and trigger a tax charge.

We model pensionable pay against the tapered allowance threshold and flag where Scheme Pays may make sense. We do not give regulated pension advice; for transfer or access decisions we work with an FCA-authorised IFA.
