In Australia it's illegal not to have the actual price customer will pay at the checkout, GST and any other fees and charges have to be inlcuded in the advertised price. Luckily we only have a single Federal tax called the GST, states do not levy sales taxes.
Well to be picky, the Australian states levy stamp (transfer) duty into certain purchases where land is involved and is clearly separate from the purchase price.
You will see breakdowns in NSW for fire service levy and emergency service levies on insurance premiums.
Excise and importation duties are other buried taxes. We even have tax (GST) on tax (Excise and importation duty) for fuel. Buried fuel taxes represent about 35% of the retail price
State payroll taxes are buried under SG&A costs.
From recent AFR article: "A challenge for the states is that they are responsible for nearly half of Australian general government operating expenditure, but their limited taxation capacity means they collect only about 25 per cent of total revenues.
The so-called vertical fiscal imbalance forces the Commonwealth to pay the states GST and other grants."
Other non-government changes include freight and "handling fees" for tickets amongst other things.
