They do, but the financial impact to you is much less.
Example
- Let's say you bough a home for $100k
- Property taxes are 1% of home value
In Year 1, you owe $1k in property taxes.
Let's say (dramatically) that property values double in Year 2.
- Now, you're $100k home is worth $200k
So your property taxes in Year 2 are now $2k.
-----
With taxing your unrealized gains at the nominal Federal & State income tax bracket.
- Your Federal Income tax rate might be 30% (dependent upon your earnings)
- Your State Income tax rate might be 10%
So you have a combined 40% tax rate on "earnings"
Now in that example of your home going from $100k to $200k in Unrealized gains, you'd have to cut a check for $40K!
That's huge and most people wouldn't even have that kind of cash to pay.
