Tax State Resilience
1. WHAT MAKES A SUCCESSFUL
TAX STATE?
Prosper Society, 2 September 2015

Professor and Director, Tax and Transfer
Policy Institute, The ANU
2. The long view: what is tax for?
“defraying the necessary expence of
any great and civilized state … this
expence must, the greater part of it,
be defrayed by taxes of one kind or
another; the people contributing a
part of their own private revenue in
order to make up a public revenue to
the sovereign or commonwealth.”
2
“That sure, steady, and permanent revenue which can alone
give security and dignity to government … for a great nation”
3. 3
Of course, government paid for by taxes
must be legitimate
The Eureka Stockade Rebellion, Australia, 1854
4. 4
“That it is the inalienable
right of every citizen to
have a voice in making the
laws he is called upon to
obey
– that taxation without
Representation is tyranny.”
And representative…
5. What is tax for?
• Public goods (benefit of government)
Some goods ‘though they may be in the highest degree
advantageous to a great society are, however, of such a
nature that the profit could never repay the expenses to any
individual or small number of individuals and which it
therefore cannot be expected that any individual or small
number of individuals should erect.’ (A. Smith, 1776)
5
Redistribution (inequality)
‘Taxation can become a regulating factor in the distribution of
national income and wealth, generally by modifying the
distribution brought about by free competition. … this second,
regulatory purpose to interference with the uses of individual
incomes and wealth … is a ‘social welfare’ concept beside the
‘purely financial’ one’(A. Wagner, 1893)

• Systems theory: The capacity of a system to
continually change and adapt yet remain stable
within critical thresholds (Brian Walker et al 2004)
• Or successfully transition to a new viable state
16
17. Tax system resilience
• Stable
• Resistant to planning
– Actual economic behaviour; and planning/arbitrage
• Low compliance, administrative costs
• Adaptable to change, eg
– Work
– Family structures
– Business and investment approaches
– Digital global economy
– Broader social or economic needs, eg environmental
sustainability
• Over short, medium- to long-term horizon

30. Stamp duties; land tax switch
• Duties are the second largest tax base
– High but volatile revenues in capital cities
– Lumpy, unpredictable
– Why borrow upfront (and pay interest) to pay a lumpy tax when can
– Duties on insurance are the most inefficient
• Land tax
– Harmonize base; change land unit
– Possible different flat rates in States?
– Low flat rate? (Prosper suggests 6%?)
• Political transition; existing land-owners will bear tax on reform –
A.C.T challenge to 2032?
• Revenues will be needed if reform is done, at least in short term
