A dental practice’s accounting records have to do something most small business books do not: keep several fundamentally different income streams and cost relationships separate all year. NHS contract income, private fees, plan income and associate arrangements each behave differently in the accounts, and books that merge them produce accounts that mislead and filings that need reworking. The checklist below is organised around those streams.

It applies to practice owners, whether trading as sole practitioners, partnerships or limited companies, and to practice managers who run the day-to-day books.

Splitting NHS and private income at source

Record NHS contract payments, private fee income and plan scheme receipts as separate income categories from the moment they are entered, and reconcile each to its own source document: the NHS statement, the practice management system’s private takings report, and the plan provider’s remittance. The split matters for understanding practice performance, for accounts disclosure and for tax treatment, and it cannot be reliably rebuilt from a merged bank feed at year end. Keep the monthly NHS schedules themselves; the bank credit alone does not show deductions made before payment.

Associate arrangements and payments

For every associate, keep the written agreement, the basis of their pay, monthly calculation sheets showing gross fees, deductions for lab work and other agreed items, and the payment actually made. Associate status is a question of fact that the practice needs to assess and document for each associate, rather than something the standard agreement determines. Keep the assessment alongside the agreement, because the practice carries the PAYE risk if the assessment is wrong. Where an associate is self employed, your records and theirs must be able to agree with each other; disputes and tax queries both start where the two sets diverge. What the associate should hold on their side is covered in accounting records for associate dentists.

Lab fees and clinical consumables

Lab invoices should be recorded against the period and, where your systems allow, the dentist whose work generated them, because associate deductions and practice profitability both depend on that link. Consumables need supplier invoices retained and a periodic check that spending patterns make sense against activity. Unmatched lab invoices are a classic source of associate pay disputes.

Equipment, surgery fit-outs and finance

Dental equipment is expensive and long-lived, so keep purchase invoices, finance and lease agreements, and a simple asset register recording what was bought, when and how it was funded. The tax treatment of equipment spending depends on the item and your circumstances, and the paperwork is what makes the right treatment available. Disposal and part-exchange documents matter as much as purchases.

The dental practice accounting records checklist

  • NHS statements and schedules, filed monthly and reconciled
  • Private takings reports reconciled to banking, including card settlements
  • Plan provider remittances, broken down by patient scheme
  • Associate agreements, monthly pay calculations and payment records
  • Lab invoices matched to periods and clinicians
  • Supplier invoices for materials and consumables
  • Payroll records for employed staff, run under the rules in the GOV.UK guidance on PAYE for employers
  • Asset register with purchase and finance documents
  • Bank and card statements for every practice account
  • Records retained for the minimum periods HMRC publishes, checking the page that matches how the practice is structured: sole practitioners and partners follow the self employed rule in the GOV.UK guidance on keeping your pay and tax records, while a limited company follows a separate and longer company rule

Where practice books usually go wrong

  • Patient refunds netted against takings instead of recorded separately
  • NHS deductions ignored, so recorded income never matches the contract value
  • Associate deductions calculated outside the books on scraps of paper
  • Card settlements banked net of charges with no gross figure recorded
  • Locum cover paid without any record of the terms

When owner-managed books stop being enough

A single-surgery practice with an engaged manager can run excellent records in-house. Multiple surgeries, several associates, mixed NHS and private contracts or an incorporation all push the bookkeeping beyond what spare hours cover. Our bookkeeping service runs stream-separated records for practices, and sister checklists exist for medical practices and pharmacies facing parallel problems.

Frequently asked questions

Why does the NHS and private split matter so much in the records?

Because the two streams differ in how income is earned, when it is recognised and how it is taxed, and because practice performance is unreadable without the split. A practice valuing itself for sale will also be asked for it immediately.

Should associate pay calculations live inside the bookkeeping system?

Yes, or at least be filed with it. Calculations kept in side spreadsheets get lost, and the deduction history is exactly what you need when an associate queries a payment months later.

How should a practice record patient plan income?

From the plan provider’s remittance, broken down to its components, not from the net bank credit. The remittance shows joining fees, monthly amounts and deductions that the bank line hides.

Do these records change if the practice is a limited company?

The record keeping is broadly the same, but a company adds statutory accounts obligations and its own filing regime, and transactions between the company and its directors need particularly clean documentation. Retention differs as well, because the company rule runs from the end of the financial year the records relate to and is longer than the self employed one. The structure changes the filings more than the bookkeeping.
