> Is the purchase of each additional car going to increase the tax paid?

Yes, tax liability = total spending during the year plugged into the power law tax formula.

>Are exotic cars taxed more?

Depends how much the taxpayer spends in a year. There is no tax rate for each specific item. The tax rate is for a total level of spending, which eliminates all loopholes.

> You keep stating to use a power law formula but you're critically omitting what the inputs are to determine your tax rate.

The input is total spend in a year. Just like right now, the input is income in a year.

> And now you've also admitted that assets determine your sales tax

No, I did not. The formula to calculate sales tax liability only requires inputting total spending. Land value taxes are a separate thing. We currently have land value taxes, except they are flat rate and too low because property taxes inefficiently tax improvements on the land more than the land itself.

> That's why the income tax is effective - it's taxation at the moment the money changes hands / you've realized a gain.

Sales tax can also be at the moment the money changes hands. It currently is. Even with the complication of a power law tax formula, I can’t see why the government can’t email you a monthly invoice.

I don't like this idea of collecting this tax yearly. I'd skip the power formula and have this tax to be just fixed percentage on every purchase to be able to collect it immediately and automatically by using the banking system itself.

My capital gains tax is immediately collected as my bank sees any capital gains. I physically can't dodge it.

Similarily I could have tax on every purchase I pay for with any kind of bank transfer immediately collected.

A flat sales tax rate is regressive. I don’t see a reason to give rich people that benefit. Roughly speaking, the effects of consumption are not linear. A private jet, yacht, and large and heavy vehicles are going to consume much more public goods (including the environment) than cheaper goods.

[scotty79]

You can skew the tax by giving more tax credit to the poor.

Also those are not only taxes on consumption but every purchase. Yacht might be too cheap in comparison of resources used but rich don't just buy yahts, they buy entire companies.

The power law formula already skews the tax rate. There’s no need to further skew it with tax credits or other complications. If you want to adjust tax rates, simply modify the curve of the power law formula so that a given level of spending is taxed a lower or higher rate.

[scotty79]

Only of you have something to feed into the power formula and you don't unless you collect data more personal than what people are used to having collected.

Some people even object to paying with cards today because they don't want their transactions to be tied together to their identity.

So alternatives to power formula that achieve similar effect in different ways might be worth considering.

> Sales tax can also be at the moment the money changes hands

Are services included in this sales tax? e.g. if I hire a cleaning company to clean my apartment? I'm assuming they would be right? Now what distinguishes that scenario from an employee being hired?

[lotsofpulp]

Yes, I don’t think I have come across a US state where sales tax doesn’t also get applied to most services.

> Now what distinguishes that scenario from an employee being hired?

Not sure why this is relevant to this discussion, but the cleaning service’s employees do not become your employees because you don’t get to manage the cleaning service’s employees and it’s usually a limited time work engagement. There’s quite a bit more that goes into creating an employer / employee relationship.

[scotty79]

In my opinion it shouldn't be different. You should pay the same tax whether you purchase service from a company or labor from an individual.
