Any tax needs to balance how nice and efficient it is on paper with how practical it is to collect in the real world.. Replacing both income and capital gains taxes with a single wealth tax would be theoretically most efficient and incentive-aligned, but wealth taxes are extremely difficult to administer in real life, so we don't do them and instead have income and capital gains taxes as an imperfect but easy-to-collect proxy.

It's the same thing with "buyer-reported sales taxes": nice in theory, impossible in practice (note that this isn't a hypothetical: as others have mentioned in the thread, before sales taxes were extended to internet purchases you were supposed to report internet purchases as use taxes, which approximately nobody did).

Right, but with electronic payments, total purchase amounts can be reported to the government, just like income is reported now.

And you do not have to worry about figuring out valuations of a million different kinds of wealth or who owns what. A much simpler formula for taxation, you spend up to $x, tax rate is y%, and so on and so forth.

> you were supposed to report internet purchases as use taxes, which approximately nobody did

There was an article on here a few days ago about someone trying to do so and no one at the state tax office could figure out what was actually needed for them to do so.

There is a place to do that on your state income taxes at the end of the year. I'm not sure how no one at the state tax office would not know that, they have an easy to understand website. Alternatively, you can report it directly to them.

Not all states have income tax

Sorry, it was an article about California, figured that was what we were talking about

fair enough, as a Washingtonian I sometimes forget that others have to deal with state income tax, definitely makes sense it'd just be part of yearly tax paperwork you already have to do.

From a quick google I think a lot of the additional confusion is the mix of Use/Sales tax when they mostly (as a customer) have the same meaning but for a tax authority have different meaning, searching for "Washington how to declare sales tax" turns up a bunch of random stuff about regulations for retailers showing sales tax correctly, if you search for "Washington how to declare use tax" actually brings up the correct documents from the state, I can def see some bureaucrat not connecting that that's what was actually meant.
