It seems fair that you shouldn't be able to have it both ways—if you are getting any financial benefit from an asset, including a loan, there's a pretty strong argument that you yourself are "realizing" that value.
I think it would be more realistic to heavily tax inheritance and re-evaluate trust based loopholes.
I mean, you’re clearly moving the goalposts here. We’re talking about tax on unrealized gains for the wealthy, not sales tax, property tax, or taxes on the bank.
If you’re able to keep taking out new loans to pay off the old loans until you die, with an appreciating “unrealized” asset as collateral, then yes all that money is effectively tax free if we’re talking about income tax and capital gains.
There is no such federal tax in the USA.
And it is just ludicrous to suggest that stock holdings cannot be subject to a wealth tax. The value of stock holdings are established all the time when the wealthy provide their net worth for their business dealings.
The IRS requires me to submit the value of my IRA holdings as of the end of the year to determine how much will be taxed the next year (by forcing me to withdraw a dollar amount - determined by the asset value of my holdings - which vary minute by minute when the markets are open). So, I guess it's ok for the IRS to measure my wealth each year to enable the IRS to collect a tax on that wealth - but some how you say that's impossible to do for billionaires?
If an equity is valued at $X on some date when we lock in the value for a wealth tax or a tax on unrealized gains then sell enough of your equities on that date to pay for the tax and store that in a zero-risk asset. This can easily be done automatically.
Real estate can already be taxed via property taxes. Unrealized gains in securities can't be taxed the same way as their value is much more volatile, with potentially large daily swings. Texas makes up for the lack of income taxes with relatively high property taxes.
>In addition to real estate I might consider other property such as bank accounts, at least above a certain threshold.
Interest from savings accounts is already taxed. The wealthy don't hoard their wealth in bank accounts though.
