The Tax Anatomy of a Medical Practice – A Tax Prescription for a Healthy Practice

If It Is Not Recorded, It Cannot Be Measured

In medicine, symptoms are recorded, tests are performed and progress is monitored.

A medical practice should be managed the same way.

If income, expenses, debtors, tax liabilities and cash movements are not recorded accurately, the financial health of the practice cannot be measured.

Strong billings can hide weak profits. A healthy bank balance can hide unpaid tax. Billing software can show claims without showing performance.

What happens behind the consulting room matters just as much as what happens inside it.

Turnover Is Not Taxable Profit

A practice may generate significant billings while retaining far less after paying expenses such as:

  • medical indemnity insurance;
  • rooms or facility costs;
  • salaries and payroll expenses;
  • billing and practice-management fees;
  • equipment and consumables;
  • professional subscriptions; and
  • administrative costs.

Income tax is generally calculated on taxable profit rather than total billings.

The problem is often not that practitioners incur too few expenses. It is that legitimate practice expenses are paid personally, poorly documented or never recorded in the accounting system.

An expense is not deductible merely because the practitioner paid it. It must have been incurred in the production of the practice’s income and must be supported by appropriate records.

Good recordkeeping is therefore part of tax planning—not simply an administrative burden.

Keep Business and Pleasure Separate

Practice income and personal spending should not flow through the same account.

Using the practice bank account for groceries, holidays, school fees or other personal expenses makes it harder to understand the true performance of the practice and increases the risk of incorrect tax treatment.

Personal expenses do not become deductible merely because they were paid from the business account.

Separate banking and disciplined recordkeeping make it easier to:

  • identify genuine practice expenses;
  • track practitioner drawings or loan accounts;
  • prepare accurate tax returns;
  • reconcile the accounting records; and
  • understand how much cash the practice can actually afford to distribute.

Provisional Tax Requires Planning

Provisional tax is not a separate tax. It is a method of paying the expected income tax liability in advance so that the full amount does not become payable only after assessment.

Waiting until a provisional tax deadline to calculate the liability can create unnecessary pressure on the practice’s cash flow.

A healthier approach is to estimate taxable profit regularly and reserve part of the practice’s monthly collections for tax.

Tax should be treated as a recurring financial obligation—not as an unexpected year-end expense.

Do Not Ignore VAT

From 1 April 2026, the compulsory VAT-registration threshold increased to R2.3 million in taxable supplies over a 12-month period. The voluntary-registration threshold increased to R120,000, subject to the applicable requirements.

A practice approaching the compulsory threshold should not wait until year-end to consider registration.

VAT registration can affect:

  • the amounts charged to patients or medical schemes;
  • billing-system configurations;
  • contracts and tariffs;
  • tax invoices;
  • the timing of registration; and
  • the recovery of qualifying input VAT.

The VAT position may also require separate consideration where the practice earns income from product sales, room rentals, administrative services or other non-clinical activities.

VAT should therefore be monitored against actual and expected turnover throughout the year.

Billing Software Is Not Accounting Software

Billing software is essential to a medical practice, but its primary purpose is usually to record patient accounts, medical-scheme claims, payments and outstanding balances.

It does not necessarily provide a complete record of:

  • operating expenses;
  • assets and finance agreements;
  • payroll liabilities;
  • tax payments and amounts owing;
  • practitioner withdrawals;
  • unpaid suppliers;
  • loans and financing; or
  • the overall profitability of the practice.

A practice may appear successful when measured by claims submitted while still experiencing weak cash flow or declining profitability.

The billing records, bank account, payroll and accounting system must therefore be reconciled regularly.

Otherwise, the practitioner may know how much was billed without knowing how much the practice actually earned.

The Bank Balance Can Be Misleading

Money in the practice bank account does not always belong to the practitioner.

The balance may include amounts needed for:

  • VAT;
  • PAYE and other payroll liabilities;
  • provisional tax;
  • unpaid suppliers;
  • staff bonuses or leave obligations;
  • equipment instalments; and
  • upcoming operating expenses.

Similarly, a low bank balance does not automatically mean that the practice is unprofitable. Cash may be tied up in medical-scheme claims, patient debtors, equipment or other working-capital requirements.

The bank account shows how much cash is available at a particular moment.

It does not explain the financial health of the practice.

Annual Financial Statements Are Not Enough

Annual financial statements remain important, but they report on a period that has already ended.

By the time a problem appears in the annual figures, the practice may have spent months:

  • operating below the required margin;
  • allowing debtors to accumulate;
  • withdrawing more than the practice can afford;
  • underproviding for tax;
  • carrying unnecessary costs; or
  • continuing with an unprofitable service line.

Monthly management reporting allows the practitioner to identify these issues while there is still time to respond.

The objective is not to create more paperwork.

It is to turn the practice’s financial records into information that can be used.

A Healthy Practice Requires More Than Tax Returns

Good tax management does not begin when the tax return is submitted.

It begins with:

  • separate practice banking;
  • complete billing records;
  • reliable monthly bookkeeping;
  • properly supported expenses;
  • regular reconciliations;
  • current management reports;
  • ongoing tax estimates; and
  • sufficient cash reserves for upcoming liabilities.

A practitioner may be highly skilled clinically while still requiring specialist support to manage the financial health of the practice.

Ongoing reporting helps the practitioner understand whether the practice is generating sufficient profit and cash to support future decisions.

This may include:

  • purchasing medical equipment;
  • employing additional staff;
  • opening another consulting room;
  • introducing a new service line;
  • obtaining finance;
  • investing surplus cash; or
  • increasing practitioner remuneration.

The purpose is not simply to complete tax returns or report historical figures.

It is to understand what the practice is earning, provide for what it owes, plan for future cash requirements and make informed decisions about investment and expansion.

A healthy practice should not discover its financial condition only once a year.

Is Your Practice Financially Healthy?

If your practice relies mainly on billing reports, bank balances and annual financial statements, you may not have a complete view of its financial performance.
