This line of thinking though assumes it would have no impact on the largest players though. It hinges on a "calling their bluff", that high NW individuals won't change anything despite now being forced to annually liquidate assets to cover taxes. And this doesn't even touch on the immense impracticality of annually valuing assets. Or how to manage assets in illiquid markets, or how to sell 30% of a painting to cover 1% of it's mark-to-market value by year end.

The reason wealth taxes never go anywhere is because when you sit down and learn what wealth is, how it works, and what is practical, it makes the most sense by far to just tax things whenever they go back to cash.

Really the only genuine tax loop-hole is the step-up basis on inheritance. Everything else is just an elaborate deferral to pay taxes later.

Allow paying the tax with assets. Put the assets into a black box sovereign wealth fund that's controlled by some mechanical algorithm which sells things at random as needed to fund the government budget. At scale this will be indistinguishable from a whole-economy index fund.

The best part about this is rich people can't beg off by saying "I have to liquidate stuff".

How do you pay with assets for real estate or boats or paintings? An IOU that can be cashed in when the asset is sold. Oh the boat is owned by an LLC so it never changes hands? No problem, the government has a share in the LLC too. (IANAL, IANAA so working out the loopholes is left as an exercise for the reader).

A second benefit is startup shares don't have to get hit with a capital gains tax before the startup goes public. Right now people sometimes pay taxes on shares that are eventually worth zero. Instead if this tax could be paid in startup shares, then there's no unfair tax bill.

As a condition of paying in assets, forbid the government from exercising any control over the assets. No shareholder voting, no board seats, not even choosing the paint color on the boat.

Additionally, this tax can't be on top of income tax. The whole point is to fix the worker-funded tax pyramid scheme. It has to be revenue-neutral with respect to income tax.

The bigger issue is, at least in the US, roughly 2/3 of assets of the wealthy have no meaningful liquidity. There is also no mark-to-market because in many cases these are idiosyncratic goods that may only find a buyer once over decades. Even some real estate markets only clear a single transaction on the scale of decades so any valuation is mostly fiction -- there are no comparables.

You could pay for these using the 30% of the assets that have some practical degree of liquidity but now you are putting massive downward pricing pressure on those because it is essentially a leveraged liquidation. Effectively, the total percentage of assets that are non-liquid would increase.

People tend to underestimate just how non-liquid the assets of the wealthy are. Most of that wealth isn't in stocks and bonds.

Real estate is a bad example because it's already subject to property taxes, which is a form of wealth tax. Maybe it doesn't need another wealth tax.

Private businesses are a better example. They don't trade on markets, sometimes don't have multiple shareholders. There already exist methods for valuing businesses (discounted cashflow, for example). Let the taxpayer pick one and make them stick to it.

I already said "no liquidations, pay with assets". For non-liquid assets pay with IOUs on said assets. The government cashes in the IOU when the asset changes hands - whether it's by sale, gift, or inheritance. Yes that's an inheritance tax; who cares? If you want to add a wealth tax to real estate, this is the way to do it.

There are a surprising number of edge cases out there.

Quite a few assets can never clear a market — they have value in some abstract sense but no concrete sense. For example, assets that are legal to own and transfer but illegal to buy or sell.

Some commodity assets have value that it is nonetheless not always transferrable. A common example relevant to wealth taxes is intangible assets where value is bound in who owns it and not the asset per se. Most of the value vanishes the instant you transfer to e.g. the government.

Another common issue is that wealth taxes can directly conflict with existing load-bearing contracts. As a practical matter, these government can’t just void most contracts, including contracts the government is a party to, for the purposes of generating tax revenue.

All of which is why most real-world wealth taxes limit scope to a handful of liquid, legible securities and similar. But as a percentage of wealth, these are pretty small so you don’t collect much revenue.

What's an actual example of this?

Such as?

While I agree with "it's more complex than it seems", some simple things are not done because of FUD and politicians.

There are countries (ex: https://en.wikipedia.org/wiki/Taxation_in_the_Netherlands#Bo...) that do tax wealth assets (maybe not all, and maybe not perfectly) and they seem to be doing just fine.
