Associate dentist tax estimator.
Gross associate income, minus dental-specific allowable expenses, against UK 2025/26 self-employed tax bands. Shows what a specialist-reviewed return typically saves vs. filing without claiming properly.
Total NHS UDA + private fees before any deductions. Before lab fee recharges.
SIPP, personal pension — not NHS scheme. Gross figure including the 20% tax relief. Optional.
UK 2025/26 rates. Assumes self-employed associate, no other employment, no student loan. Does not model payments on account, limited company structure, or high-income child benefit charge. A specialist models what this tool can't — and usually finds a few hundred more in allowable expenses the first year.
What this doesn't do.
- Assumes self-employed (BDA template contract). Doesn't model limited company structure, which has different tax mechanics and IR35 implications.
- Doesn't model payments on account — the cash-flow cycle of HMRC collecting next year's tax in January and July.
- Doesn't handle student loan repayments or high-income child benefit charge (HICBC, triggers above £60k).
- Expense defaults are typical — actual allowable claims depend on your specific contract terms, equipment ownership, and cross-practice arrangements.
Questions.
Which expenses are genuinely allowable for an associate?+
The defensible set: GDC registration, indemnity insurance, CPD, professional subscriptions, uniform/scrubs/PPE, small tools and equipment you own, and mileage between practices (not home to a single practice). Lab fees depend on your contract — if you pay labs directly and recharge the practice, the treatment differs from the practice paying and deducting from gross. A specialist documents the basis for each claim.
Does this include payments on account?+
No. Payments on account are HMRC collecting half of next year's estimated tax in January and half in July — it doesn't change your actual tax bill, it changes the cash-flow timing. For associates whose income grew last year, POA can feel like a double hit. A specialist can apply to reduce POA if your income is genuinely falling.
Should I incorporate to a limited company?+
Rarely a simple answer. For most associates on standard BDA contracts, a limited company triggers IR35 concerns and makes pension contributions more complicated. For some higher-earning associates with mixed income streams, it can still make sense after proper modelling. A specialist runs the numbers both ways — incorporation isn't automatic.
How accurate is this for my actual tax bill?+
Within 5% for straightforward cases (single practice, no student loan, no other employment). Larger variance if you have complex income (multiple practices with different expense splits), limited company involvement, or income near a band boundary where edge effects matter. Use it to sense-check — the self-assessment return done by a specialist is where the real numbers land.
What about the NHS pension — is that covered?+
Partly. Pension contributions to your personal SIPP get relief here via the extended basic-rate band. NHS pension contributions are deducted at source via payroll, so they don't appear on a self-employed associate's self-assessment (they're handled separately by the NHS). For annual allowance concerns, use our annual allowance estimator instead.
Where a specialist picks up.
The estimator handles the arithmetic. A specialist handles the parts that matter more over a full career: cross-practice expense allocation, HMRC status defence, pension timing across the basic-rate band, and honest incorporation modelling.
