Incorrect. The rate is quoted both ways to facilitate comparison to the income tax. A 30% sales tax is equivalent to a 23% income based tax. There is no intent to deceive, rather advocates wish to provide a valid basis of comparison. A 30% sales tax is NOT equivalent to a 30% income tax and those who don’t think about this at any depth would equate the two. In a rush to judgment, without a valid basis of comparison, most would dismiss the proposal out of hand as a tax increase. That is false.
Just as any other sales tax.
If you said the truth, according to how we compute sales taxes, 30%, then you would have a greater risk of having the prospect run away from you as fast as he could.
Then you would have to shout "wait you haven't heard about the pre-bates yet!"
