APPENDIX ADJUSTED MEASURES OF GOVERNMENT REVENUE
ADJUSTED MEASURES OF GOVERNMENT REVENUE
The taxation revenue statistics presented in this release are in accordance with the Australian system of Government Finance Statistics (GFS). This system is outlined in the Australian System of Government Finance Statistics: Concepts, Sources and Methods (cat no 5514.0) which is consistent with the International Monetary Fund's Government Finance Statistics Manual 2001 (IMF GFSM2001).
The GFS framework reflects taxation revenue collected by each level of government. The purpose of this appendix is to consider an alternative presentation of revenue which takes into account the level of government at which revenue is used rather than simply collected. The analysis considers the flows, by way of current grants, that occur between the levels of government in Australia, and the impact that this has on revenue at each of these levels. Also considered is the effect of direct and indirect transfers to households on total revenue. To aid in the understanding of these flows, the following analytical measures of revenue have been derived. Users should note that these measures are not themselves part of the GFS framework.
Adjusted taxation revenue
Adjusted taxation revenue is equal to GFS taxation revenue collected by each level of government, plus current grants received from higher levels of government, less current grants paid to lower levels of government. This measure is designed to give a clearer indication of the levels of government at which taxation revenue is actually used or spent. The source for a significant amount of the current grants distributed between levels of government is taxation revenue, such as the GST. However, some of the revenue distributed may have come from a source other than taxation. Further, it should be noted that some of the current grants transferred from Commonwealth to the states are Specific Purpose Payments (SPPs). Unlike the GST-related grants, these payments are 'tied' to specific policy areas or programs as agreed between the two levels of government. Similar arrangements exist between the states and local government. SPPs for current purposes are included with other current grants in deriving adjusted taxation revenue. The ABS does not have the data required to separate out SPPs from other grants.
Adjusted total revenue
Adjusted total revenue is equal to adjusted taxation revenue plus all other non-taxation sources of revenue. Non-taxation revenue includes revenue from sales of goods and services, property income (interest, dividends, income tax equivalents, land rents and royalties), fines, capital transfers, and current transfers other than grants. Current grants are excluded from non-taxation revenue because these have already been taken into account in deriving adjusted taxation revenue.
Adjusted total revenue less transfers to households
An important role of government is the redistribution of income, by way of direct and indirect 'benefits', to individual households. These transfers can be deducted from adjusted total revenue to derive adjusted total revenue less transfers to households. Direct benefits are regular cash payments made to households by government without any requirement to provide goods and services in return (for example, welfare payments). Indirect benefits are non-cash benefits and services provided by government to individual households (for example, concessions for transport and utilities, as well as natural disaster relief).
The three derived measures explained above are illustrated in the following diagram:
An analysis along similar lines was previously published in the March 2006 issue of Australian Economic Indicators (cat. no. 1350.0), in a feature article entitled "Recent Taxation Revenue Trends in Australia". This article included information on the introduction of The New Tax System on 1 July 2000.

Taking into account taxation revenue distributed by the Commonwealth government to both state and local levels of government by way of current grants, the level of adjusted taxation revenue at the Commonwealth's disposal in 2005-06 was $178,173 million. This represents a 7.1% increase from the previous year, compared with a 7.0% increase in directly collected taxation revenue. Adjusted taxation revenue for the Commonwealth was 59.8% of total taxation revenue in Australia in 2005-06, compared with 59.3% in 2000-01.
Adjusted taxation revenue at the state level of government in 2005-06 was $103,211 million. This represents a 6.5% increase from the previous year, compared with a 6.2% increase in directly collected taxation revenue. Adjusted taxation revenue at the state level of government was 34.6% of total taxation revenue in 2005-06, compared with 34.9% in 2000-01.
The two graphs below show taxation revenue and adjusted taxation revenue as a proportion of GDP for each level of government. Graph 1 shows that in 2005-06 taxation revenue collected by the Commonwealth was equal to 25.4% of GDP whereas taxation revenue collected by states was equivalent to 4.6% of GDP. After taking into account current grants (adjusted taxation revenue in graph 2) these proportions change to 18.4% and 10.7% respectively.

Adjusted total revenue for the Commonwealth in 2005-06 was $193,543 million, up 8.0% from the previous year, compared with an increase of 7.1% in adjusted taxation revenue. For the state governments, adjusted total revenue in 2005-06 was $140,159 million, an increase of 8.1%, compared with an increase of 6.5% in adjusted taxation revenue.
Graph 3 shows the adjusted total revenue for each level of government and graph 4 shows the amounts as a percentage of GDP.

Graph 4. Adjusted total revenue, As a percentage of GDP

When direct and indirect transfers to households are taken into account, Commonwealth revenue falls to $93,757 million in 2005-06 compared to $137,329 million for all state governments. This is largely because of the income redistribution role performed by the Commonwealth through the welfare payment mechanism. In 2005-06, 51.6% of the Commonwealth's adjusted total revenue was transferred to households. This figure was 54.6% in 2000-01. In 2005-06, the Commonwealth's adjusted total revenue less transfers to households grew more quickly (12.9%) than adjusted total revenue itself (8.0%).
Graph 5. Adjusted total revenue less transfers to households

After adjusting for transfers to households and comparing to GDP, there has been a slight upwards trend in total revenue available to Commonwealth and state governments since 2000-01. Commonwealth adjusted total revenue less transfers to households was equal to 9.0% of GDP in 2000-01 and had risen to 9.7% in 2005-06. The corresponding state measure had risen to 14.2% of GDP in 2005-06 compared to 14.0% in 2000-01.
