ACCOUNTANCY
As tax advisors, one of the most common 
questions we hear at William Buck from our 
medical clients is: "Should I carry on my 
practice through a company?"
In the past, many medical professionals 
incorporated their practices for a number 
of reasons, including the perceived benefits 
of limited liability and the belief that 
the company can retain profits and that 
companies have access to better deductions 
for superannuation contributions.
Are these still good reasons to 
incorporate in today's business and 
taxation environment? And what are the 
benefits of incorporating versus operating 
through an unincorporated structure 
(sole trader)?
PROS & CONS
Listed below are some of the benefits and 
disadvantages of operating a medical practice 
through a company and as a sole trader:
Well Structured
Will incorporating your medical practice bring benefits, or is setting up as a sole 
trader the way to go? 
Julie Smith offers some expert advice.
 Incorporated practice
 Sole trader
Benefits
·  Some level of limited liability may be 
available, but would depend on the 
nature of the claim.
·  Ability to pay tax on income 
monthly, which can ease the strain 
on cashflow.
Benefits
·  Inexpensive to establish.
·  Sole trader profits are not subject 
to payroll tax.
·  Equal access to superannuation 
deductions as a company. 
Disadvantages
·  All profits must be paid to the 
doctor by way of wages or 
superannuation.
·  Exposure to payroll tax in relation 
to salaries and superannuation paid 
to staff (including those paid to 
the doctor).
·  Cost of establishment and annual 
compliance and regulatory 
costs apply.
·  We understand that corporate 
limited liability usually does not 
apply where there is a failing on 
a professional level.
Disadvantages
·  No access to corporate limited 
liability  your personal assets may 
be accessed by creditors to pay 
business debts.
·  Your tax bills are less regular, so 
you need discipline in saving for 
your tax as you earn your money.
As you can see, there is no great tax 
benefit in structuring through a company. 
On this basis, it is often our advice to 
structure your practice through a sole trader 
 it's the simplest and most cost-effective 
structure. This will not apply to everyone 
however, and you should discuss your own 
particular circumstances with a tax advisor 
before deciding how best to structure 
your practice.
