No, the renewal fee is fixed. The comment you're responding to suggests taxation on an appraised value. If you're sitting on a domain name for which there are documented offers of, say, $100,000, an appraised tax would assess you annually N% of $100,000.
> We manage to assess real estate without running into those problems.
We also don't generally use the documented offer standard you suggest for domain names for real property, but on objective features of the property, replacement costs based on those objective features, and application of a depreciation schedule to those features subject to depreciation.
Of course. I don't think documented offers is how the scheme would actually be implemented. Of course: I don't think any scheme like this would be implemented in the first place.
Eh, California takes the sales price as the base price and has a 2% annual cap on increases. I guess you could charge a little bit more every year for domains, but that feels extortionist.
