Yes but many of the assets that were acquired from Billiton as part of the merger have subsequently been sold off. Perhaps the most significant lasting effect was the dual-listing. Maybe someone in the Creative Financing Department at BHP decided that they might as well use the dual-listing for something.
What makes this even a meaningful comparison? I mean why would anyone think that the ratio of tax collected from companies to the tax collected from individuals should be any particular number? The change over time is probably more significant than the actual number (the ratio).
Businesses’ profits are more volatile than individuals’ taxable incomes. Maybe business really was struggling.
It won’t be showing up on the graph yet but smaller businesses have had a reduction in the company tax rate.
Another factor is bracket creep. Because there is (more or less) only a single company tax rate, business is not subject to bracket creep, whereas individuals of course are.
To the extent that a business has only Australian shareholders and distributes its after tax profits as dividends, it really doesn’t make any difference what the company tax rate was - because of the imputation credit (franking credit) system. It could be artificially high and the green line would go shooting up. It could be artificially low and the green line would go shooting down. However in either case the Australian government’s budget position, and the shareholder’s financial position, would be essentially unchanged! It would just be swings and roundabouts.
So what was the increase for enterprises over the same period?
Also, the graph uses the word “levied” rather than the word “collected”. Neither word makes it clear how the implicit double counting that is addressed by imputation credits is being represented in those numbers.
It is important to understand what the ATO means by ‘tax gap’. From the ABC’s equivalent article:
The tax gap measures the theoretical difference between the total amount of income tax collected and the amount the ATO estimates would have been collected if every one of those taxpayers was fully compliant.
It is unclear what is meant by “compliant” since it may be that every one of those taxpayers is fully compliant with the law i.e. creatively reducing their tax but not violating tax law. Maybe what the ATO means is “if every one of those taxpayers took no steps to reduce their tax”.
Ignoring that question, we should note the words “theoretical” and “estimates”.
Also from the same article:
It was also lower than the ATO’s estimate of the small business tax gap of $11 billion annually
So, in perspective, if there is rorting alleged then “rich Australians” are rorting only chicken feed, as compared with small business.
What is a “rich Australian”, you may ask?
individuals who, together with their associated entities, control net wealth of $50 million or more
