The document discusses the increasing complexity of Australia's tax system, which has expanded from around 1,080 pages in the 1950s to over 14,000 pages due to various policy adaptations. This complexity results in significant compliance costs, estimated at $40 billion annually, with small businesses particularly burdened. A more streamlined tax policy applicable to all taxpayers could potentially reduce this complexity and associated costs.

2. How did it get so complex?
2
In the 1950s Australia had a
tax system made up of
around 1080 pages of tax
law.
Since then, Governments
have identified gaps,
addressed omissions, and
attempted to adapt the tax
system to changes in
business and society.
Our tax system is now a
complex patchwork of rules.

3. Layer on layer of complexity
3
As the world has become more
complex, so has Australian tax law.
We now have more than 14,000
pages of tax law dealing with
countless specific scenarios.
This has resulted from trying to
deliver different policy outcomes,
for different taxpayers, in different
situations. Having fewer policies
that apply to all taxpayers, rather
than a range of different policies
for different taxpayers, would help
to reduce complexity.

• More complexity means higher
compliance costs; that is, the
time and money the
community spends complying
with tax obligations.
• The most recent estimate
places the compliance costs
associated with taxes the ATO
administers in the order of
$40 billion each year.1
• Small business in particular
bears the burden of
compliance costs associated
with a complex system.
The knock-on effect of complexity

Treasury, Stocktake of Regulation Final Report March 2015 (2015).

5. • 12.8 million Australians lodged personal tax returns.
• 73.5% of these used a tax agent or accountant.
• The average cost of managing tax affairs was $370 per
person - a total cost of more than $3 billion.
• 8.3 million had “simple tax affairs.”1
• But 5.4 million of these still used a tax agent or
accountant.
1 Simple tax affairs - includes anyone without any: net rental income, capital gains, business income, trust income or
income from certain overseas entities.
