Yes, I pay property taxes every year that are based on the current assessed values of my home and car. Only special classes of assets are subject to property taxes. "Wealth tax" proposals are a generalization of the idea of real property taxes so as to stop penalizing specific asset classes like homes.
If you dig into how property tax is allocated, your tax will only go up if your house appreciates more than similar properties - which usually has something like redevelopment or other externality.
It is normally not a fixed percentage of your value, but simply "here's what the county/city paid this/next year, divided amongst the properties proportionate to the value."
Some, like sewer, etc, are per-property, but most are done via the above.
California is an outlier because of Prop-13 but that makes it usually better except when buying.
Side-effects of this can mean that development in your district can reduce your tax rate, depending on what kind of development and who lives there (as property tax is often mainly a school tax, a development for 55+ will bring in more tax payers but not increase the school burden noticeably).
Right. Property taxes are a combination of fee-for-service for infrastructure, and a "congestion tax" for occupying land that nobody else can use. It's explicitly not a wealth tax because you owe it even if you have 0% equity.
You owe tax based on your percentage of ownership. The taxing authority doesn't care about equity because you own 100% of your house (albeit with a lien) even if your outstanding mortgage obligations exceed the value of the house. Generally, when you close on a house in the US, you walk away with the title to the house and a mortgage equal to a large percentage of the house's value. The bank only owes property taxes if they foreclose on the property and take the title from you.
I'm sure it depends on the jurisdiction, but all the property taxes I have ever paid (which, to be fair, has been in one county) have been a fixed percentage of the value of the property.
I don't think the percentage has changed since I moved here, though the dollar amount I pay has gone up significantly as the assessed value of my house has risen.
Like with any tax, I'm guessing the rate would change if the county's revenues didn't match their expenses?
In my county, tax rates have to be renewed every year. So every year there's a chance for the rates to change. There is an automatic suggestion of a "no new revenue" option formulated by the appraisal district based on their new assessments, there are then voter approved changes, and then the county (or taxing entity) decides.
My property taxes have practically only gone up over the years, but the tax rates from the various entities have mostly trended downwards.
