GST is a Federally raised Tax which is 100% returned to the states.
The ONLY way the GST rate can change is with the approval and the want of a majority of states.....the Federal Government has NO ability to raise the GST rate.
Note.......how long before states do introduce a GST?
My view is...not long!
i can see states acting alone putting a GST on all transactions.
They could drop a few then like the onerous vendor tax in NSW......payroll tax etc.
You willsee it sooner then later.
It is almost the perfect tax.....its a tax on consumption.
