Self assessment doesn&#x27;t really solve anything, especially if it&#x27;s for unimproved value (which is the tax basis in LVT), but all other important uses (including, e.g., eminent domain) use as-is, improved value.<p>Self-assessment is arguably efficient for setting tax basis value for things with ad valorem taxes when it serves as a firm and irrevocable offer to sell at the price (e.g., if it were the firm, out upper limit, value for eminent domain purposes.) But when the value taxed if definitionally different from the price expected in any transaction, as it is worth unimproved land value taxes, self assessment is trivially fallbacks to the point of uselessness.<p>In any case, I&#x27;m unconvinced that land value tax makes sense in a post-industrial economy; in an agricultural economy out industrial economy, sure, I can see the attraction.
