&gt; Considering 30% of US land is owned by federal government (and there&#x27;s more by states and municipalities), how would this replace the income taxes?<p>By taxing the land <i>not</i> owned by the federal government, since obviously it can&#x27;t tax itself.<p>&gt; Federal budget is comprised of 46% personal income taxes and 13% federal income taxes, so roughly two-thirds of it would have to be replaced by land value tax.<p>So? Look, to replace the <i>entirety</i> of federal revenue (which is more than you need to replace, since obviously things like fees for <i>uses</i> of federal land, which are part of federal revenue, aren&#x27;t going to go away with a land-use-tax scheme) with land use tax on the 70% of land not in federal use, assuming a flat per-acre tax (which has the virtue of making calculation easy, even if its not the most likely tax scheme), you&#x27;d need an annual tax of $3.02 trillion &#x2F; 1.7 billion acres, or a land-use tax of about $1776 per acre per annum.
