The land value tax, explained

Henry George's remedy in one idea: stop taxing what people make, and collect the value of the ground that nobody made.

The idea in one paragraph

A land value tax is a yearly charge on the value of a piece of land by itself, as if nothing were built on it. The house, the shop, the factory and everything inside them go untaxed. George proposed raising public revenue this way in place of taxes on wages, sales and buildings. He put the whole remedy in a sentence: keep land in private hands, and collect its rent for the public.

“It is not necessary to confiscate land; it is only necessary to confiscate rent.”

Where land value comes from

Picture two identical empty lots, one downtown and one an hour out of town. The downtown lot might sell for many times more, and the owner didn’t do anything to make that true. The difference comes from everyone else: the people who live nearby, the businesses that opened, the roads and schools the public paid for.

George called this value rent, and his law of rent explains how it’s set. The poorest land anyone needs to use sets a baseline, the margin. Whatever a better site produces above that baseline goes to whoever owns it, whether they work it or not.

Wages and interest: 25 on every plot in use. Rent takes 23% of all that is produced.

Each bar is a plot of land, best on the left. The poorest land in use sets the margin: what labor and capital earn there, they earn everywhere. Everything above the line is rent. George’s illustration, III.6 ¶30

Why George thought it would fix things

As a society grows richer, the margin gets pushed onto poorer land, so rent takes a bigger share of every gain and wages take a smaller one. That’s the heart of the argument in ten steps. Worse, owners who expect prices to rise have a reason to hold good land empty and wait, which forces everyone else onto worse land than they need to use.

Wages and interest: 18 on every plot in use. Rent takes 38% of all that is produced.

George’s example: owners expecting rents to rise ask 3 for land of 20, 2 for 19 and 1 for 18, and keep it idle until they get it. Labor is pushed onto land of 17, below the margin production needs. George’s illustration, IV.4 ¶11

“The increase of rent explains why wages and interest do not increase.”

What the tax changes

Three things follow when the public collects land value instead of taxing work and building.

First, building and working stop being punished. Put up a better building or hire more people, and your tax bill doesn’t rise. Second, holding land empty starts to cost money, so owners have a reason to use it or sell it to someone who will. George thought this would raise wages. Third, the value the community creates goes back to the community, and it can’t be passed on to tenants, because taxing land doesn’t make any less of it.

Taxes on wages, buildings and trade fall on what people make, and discourage making it. George moves the whole burden onto the one thing nobody made. George’s illustration, VIII.2 ¶19

What it isn't

It isn’t a tax on your house. It isn’t the government taking land, and it isn’t a new tax on top of everything else; George meant it to replace the taxes that fall on work and trade. And it isn’t a judgment of anyone who owns land today. Owners are following the rules they were given. The case here is for changing the rules, gradually, so the gains of a growing town are shared by the people who make the town grow.

The objections page takes the hard questions one at a time: farmers, homeowners on fixed incomes, retirees, whether landlords can pass it on, and how land gets valued apart from buildings.

Has anyone tried it?

Not all the way, and I won’t hide behind that. “It’s never really been tried” is what people say about every big idea with an awkward record, and it convinces nobody. There is a fairer test. George’s claim is about direction: move taxes off buildings and work and onto land values, and you should get more building, less idle land, and revenue that costs the economy very little. So the honest question is whether places that moved partway got partway those results.

What the evidence shows

  • Pittsburgh built more. After Pittsburgh raised its land tax to more than five times its building tax in 1979 and 1980, it saw “a dramatic increase in building activity, far in excess of other cities in the region” (Oates and Schwab, 1997). The authors credit an office shortage as “a primary driving force” and give the land tax “an important supporting role.”
  • Pennsylvania’s split-rate towns got denser. Across Pennsylvania census tracts from 1970 to 2000, adopting a split rate increased the number of housing units, built in a denser pattern, as the theory predicts (Banzhaf and Lavery, 2010). Harrisburg still taxes land at about six times the building rate (city code), and the city and land tax advocates say its vacant structures fell from over 4,200 in 1982 to under 500 by 2001 (Strong Towns). No independent study has tested that figure, so I treat it as a claim.
  • Hong Kong paid for its city with land. Nearly all land is leased from the government, and land revenue covered about 79 percent of infrastructure spending from 1970 to 1991 (Lincoln Institute). Salaries tax tops out at 15 percent, or 16 percent above HK$5 million (GovHK), with no sales tax, VAT, or capital gains tax (Treasury Bureau). But land money swings with the market, falling to HK$13.5 billion in 2024-25 (Budget), and the Lincoln study ties the system to very high property prices.
  • Singapore banks its land value. The state owns about 90 percent of the land (Phang, 2024), and about three in four residents live in public housing (HDB). Lease sales go into the national reserves, and the budget may spend up to half of their expected returns (Ministry of Finance), about 17 percent of total revenue in FY2024 (Budget 2025). The reserves hold more than land money, and like Hong Kong, Singapore is a state landowner with very high property prices.
  • Estonia keeps it simple. Estonia has taxed land and not buildings since 1993, a modest but stable source of local revenue (Lincoln Institute). The Tax Foundation ranks its tax code first in the OECD for the 13th year running, and its property tax first because it applies only to land (Tax Foundation, 2026).
  • Australia measured the cost. Australia’s Treasury found stamp duty on property sales lost about 72 cents of welfare per dollar raised, while a broad land tax was the most efficient tax it modeled, at roughly zero (Australian Treasury, 2015).

Why it keeps getting repealed

Look at how these policies end. Pittsburgh dropped its split rate in 2001 after a countywide reassessment sharply raised land values and residents objected (Chicago Fed). Altoona dropped its land-only tax in 2016. Officials said they never saw clear results, and they blamed the city’s small slice of the bill and public confusion (Altoona Mirror). Canberra’s switch from stamp duty to land-based rates has stalled (Canberra Times), and Detroit’s plan never reached a final vote in the state House (BridgeDetroit).

None of these ended because the tax stopped raising money or wrecked the economy, which is a different kind of failure from a system that collapses under its own economics. The pattern is political. A land tax sends a large, visible bill, often to homeowners right after a reassessment, while its benefits are spread thin across future builders, renters, and taxpayers who may never know they gained. Concentrated losers organize, and diffuse winners don’t. I suspect any reform has to plan for that game with slow phase-ins and predictable assessments, and it is no knock on the people who pushed back. Fairhope, Alabama, which took politics out of it by private contract, has run on land rent since 1894 (Fairhope Single Tax Corporation).
