In 1879 an American journalist published a book arguing that the entire tax system should be replaced by a single tax, on the value of land. The journalist was Henry George. The book was Progress and Poverty. The proposal became the most argued-over piece of tax design of the nineteenth century, and it is still argued over, for a reason that has nothing to do with its author: the case for taxing land value is the strongest case in tax economics, and the policy George proposed has, in its complete form, essentially never been run.
That mismatch is why the argument isn’t settled: critics attack the version in which land is the only source of revenue, which almost nobody has tried, while defenders point to the land taxes that do exist, which are a different thing.
The idea carries three separate proposals. What follows separates them, and then works through what has actually been levied, jurisdiction by jurisdiction, with the results for each.
What George Actually Proposed
George’s proposal was not “levy a land value tax”. It was larger. Land, he argued, should be treated as common property, and all of the rent it yields taken for public use. The sentence he set as the conclusion of his remedy is flat: “We must make land common property.” (Book VI, Chapter 2.)
The single tax is his implementation of that principle, not the principle itself.
Quote
“The tax upon land values is, therefore, the most just and equal of all taxes… It is the application of the common property to common uses. When all rent is taken by taxation for the needs of the community, then will the equality ordained by Nature be attained.”
- Henry George, Progress and Poverty (1879)
He set four requirements for the best tax: that it bear lightly on production; that it be cheaply collected and fall on the ultimate payer; that it be certain; and that it bear equally. He argued land value satisfies all four, because the worth of a site is created by the growth of the community around it rather than by anything its owner does.
One design detail is usually lost. George chose the tax over taking the land: it does not penalize people who have already improved their land, and it does not require unwinding titles already granted. At the published debate between George and the socialists in New York in 1887, the socialist speaker summarized his position for him: “Mr. George does not advocate the nationalization of land… All he wants is to confiscate the rent which the present proprietor of the land gets by a taxation equivalent to the whole rent.”
A Free Trader, and Not a Socialist
He was a free trader, and he wrote a book about it. Protection or Free Trade (1886) asks “whether protection or free trade better accords with the interests of labor”, and concludes that tariffs raise prices for consumers without raising wages, and shield monopolists from competition.
Free trade was incomplete, in his framing, without land reform. “True free trade, in short, requires that the active factor of production, Labor, shall have free access to the passive factor of production, Land.” He treated the two as one doctrine.
He was equally explicit that this was not socialism. The primary text is his open letter to Pope Leo XIII, The Condition of Labor (1891).
Quote
“We differ from the socialists in our diagnosis of the evil and we differ from them as to remedies. We have no fear of capital, regarding it as the natural handmaiden of labor; we look on interest in itself as natural and just… We would simply take for the community what belongs to the community, the value that attaches to land by the growth of the community; leave sacredly to the individual all that belongs to the individual.”
- Henry George, The Condition of Labor (1891)
He called his own side “we who call ourselves single-tax men”. Karl Marx dismissed the single-tax platform as “capitalism’s last ditch”. This was a live dispute, not a later gloss on it.
One limit worth recording: his other proposals included state ownership of natural monopolies such as railroads and the telegraph, but it’s not clear how strongly he held those views.
Three Different Things Called Georgism
George’s single tax. All land rent taken for public use, all other taxes abolished. This is a claim about the entire revenue system, and it is what the book is actually about.
A modern land value tax. A tax on the unimproved value of land, levied alongside the other taxes, usually at a modest rate, and normally with exemptions for owner-occupied housing and agricultural land. It concedes nothing about whether other taxes should exist. This is what the evidence speaks to, and every figure below is about this.
Land value capture. The state owns the land and takes the value as a landlord: sale premiums, ground rent, lease renewals, development charges. Hong Kong and Singapore are the standard examples, and both get cited as working land value taxes constantly.
Most criticism of “Georgism” is aimed at the first, and most of the evidence is about the second. A reader who checks one against the other finds that it does not fit, and concludes that somebody is being slippery.
The Case Economists Agree On
This part is not contested. Adam Smith held that ground rents are “perhaps, the species of revenue which can best bear to have a peculiar tax imposed upon them”; Milton Friedman called a tax on unimproved land value the “least bad tax”; William Vickrey argued that replacing business taxes with site value taxes “would substantially improve the economic efficiency of the jurisdiction”.
The reason is set out in Taxes - Who Actually Pays. The quantity of land cannot be reduced by taxing it, so the usual cost of a tax - the activity it discourages - has nothing to discourage. The charge falls on the owner, and the standard argument adds a step: a charge on holding land pushes idle land into use. That step is an assumption rather than an accounting identity, and it is the one the record below tests.
What Has Actually Been Enacted
Land taxes are not exotic. A dozen jurisdictions levy one at national or state level.
Estonia. A national land tax, maamaks, on the value of the land only, with no buildings in the base. In force since 1993, when the Land Tax Act was passed and the first bills fell due that November. The rate was 0.1% to 2.5% up to 31 December 2024, and from 1 January 2025 is 0.1% to 1.0% on residential land, 0.1% to 0.5% on profit-yielding land and 0.1% to 2.0% on other land. The state’s Tax and Customs Board administers it, municipal councils set the rate inside the statutory band, and 100% of the revenue goes to municipalities.
On the administrative objection, Estonia is informative. The Economist reported in February 1998 that valuations had been posted on maps in town halls and that the tax collected at a 95.5% rate in 1996 with few appeals. Two facts belong together: The Economist called it “one of the most important sources of funding” for rural municipalities, and the OECD’s Revenue Statistics 2023 records property taxes at under 1% of total tax revenue there. It funds local government but not the country.
Denmark. Grundskyld, a municipal land tax on the assessed value of the land only, on a base of 80% of that assessed value. The OECD records the municipal rate band at 1.6% to 3.4%. The cap was cut from 34 per mille to 30 per mille from 2024, and the 2024 reform added per-municipality caps through 2028 and a 4.75% annual limit on increases for non-owner-occupied property. The year grundskyld began could not be sourced: a 1903 valuation law appears in a tertiary footnote, which implies a starting point rather than establishing one, so no date is printed.
Denmark is also where a false claim circulates, worth mentioning because it gets frequently repeated. A university course note states that Denmark collects 50% of its revenue from land-valued tax. The OECD puts all taxes on property in Denmark at 1.9% of GDP, and property taxes at 1.8% to 1.9% of total tax revenue. The 50% figure is wrong.
Taiwan. Two separate taxes. The land value tax falls on declared land value, which must sit between 80% and 120% of the government’s announced land value: a basic rate of 1%, rising through 1.5%, 2.5%, 3.5%, 4.5% and 5.5% on the cumulative value above a starting point, with 0.2% for self-use residence and 1% for industrial and publicly owned land. The land value increment tax falls on the gain at transfer: 20%, 30% and 40% since February 2005, where the structure set in 1977 had been 40%, 50% and 60% and was halved for 2002 to 2004.
Taiwan’s weak point is the base rather than the rate. Ministry of Interior figures reported for 2016 put the national average announced land value at 20.50% of normal market transaction price, while the announced present value used for the increment tax stood at 90.53%. That 20.50% comes from a private company’s write-up of the ministry’s statistics rather than the ministry’s own release, so it carries that caveat. Agricultural land sits outside the base.
Australia. Every state taxes unimproved land value. New South Wales levies a statewide land tax on unimproved value with a general threshold of $1,075,000, computed on a three-year average of values supplied by the Valuer-General - the smoothing that makes an annual charge on a volatile asset practical.
Pennsylvania. Split-rate taxation, where land is taxed at a higher rate than buildings. The enabling law dates from 1913, Harrisburg has used it since 1975, school districts since 1993 and boroughs since 1998. Ratios run from about 4.5 to 1 in Allentown and 5 to 1 in Harrisburg, up to 24 to 1 in DuBois and 30.75 to 1 in Washington. Altoona went the whole way and taxed buildings at zero, which makes it a land value tax in fact rather than in degree.
The count of these municipalities peaked in 2000 and then fell. By 2006, Lincoln Institute research had processed 33 of them: 16 levying a split rate, 5 rescinded, and 12 that considered the change and never implemented it. Pittsburgh rescinded in 2001 after a countywide reassessment, and Altoona reverted in 2016. Which of the rest still levy one in 2026 is not established, so no current count is printed.
The outcome evidence is narrower than it is usually presented. Oates and Schwab, writing in the National Tax Journal in 1997, studied Pittsburgh, and Plassmann and Tideman, in the Journal of Urban Economics in 2000, found that two-rate cities showed increased construction relative to similar single-rate cities. That is evidence about splitting a rate, not about funding a government from land. Altoona’s repeal carries the detail that matters: the mayor gave two reasons, neither of them administrative impossibility - limited impact, when school district and county property taxes dominate the total bill, and unfamiliarity, because businesses and residents did not understand what had been done to their rates.
What Was Cut Back, and Why
Britain, 1909. The Finance (1909-10) Act 1910 imposed land duties, including an increment value duty of 20% and an undeveloped land duty of about 0.208% a year, and required a statutory valuation of all land in the United Kingdom as at 30 April 1909. All of it was repealed by the Finance Act 1920, section 57, which provided that “the land values duties shall cease to be chargeable” and that the obligation to value all land in the UK “shall cease”, while keeping the mineral rights duty. A second attempt came in 1931, at about 0.42%, and was repealed the same year. That episode rests on a single secondary source and has not been checked against the statute or Hansard, so it is recorded with the warning rather than offered as a fact.
New Zealand. A national land tax ran from 1878, and from 1894 it was levied on unimproved land value only, which makes it a land value tax proper. It was repealed by the Land Tax Abolition Act 1990, with effect from the payment year beginning 1 April 1992 - by a National government that had also abolished estate duty and was cutting the tax take.
Ireland. This is the cleanest case in the record, because the officials wrote down their reason. Ireland had no recurring residential property tax after domestic rates were abolished in 1978, and a residential property tax that ran from 1983 to 1997 was abandoned when only about 2% of households were paying it. A site value tax then became a formal government commitment in 2009, costed in the National Recovery Plan 2010-2014 at €180m for 2012, €355m for 2013 and €530m for 2014.
In 2012 an inter-departmental group recommended against it, on the ground of “likely difficulties in ensuring acceptance by taxpayers, i.e. arriving at values that are evidence-based, understandable and acceptable to the public, in addition to the complexities and uncertainties in the valuation effort”. Ireland introduced the Local Property Tax in 2013 instead, on the market value of the property including improvements, at 0.18% up to €1m and 0.25% above. It yields about €500m, roughly 7% of local government revenue and under 1% of total tax revenue, and Revenue Ireland describes it as “a tax on land and buildings, and not a land or site value tax”.
Canada and the single-tax colonies. Land value taxes were common in western Canada around 1900, and in Vancouver the land tax became the sole form of municipal taxation in 1910; on one academic account, by Gary B. Nixon in 2000, the rate never exceeded 2% of land value, too low to prevent the speculation that led to the 1913 crash. Fairhope in Alabama, Arden in Delaware and Free Acres in New Jersey were private corporations rather than governments. That material rests on single citations and needs a primary check.
Two Places That Are Not Georgism
Singapore. Property tax falls on Annual Value - the estimated annual rent of the whole property, land and building together - at rates from 0% to 32% for owner-occupied homes and 10% for commercial and industrial property. That is a tax on rental value. The state separately owns much of the land and grants 99-year leases, capturing value as a landlord at the moment of grant; the share it owns could not be sourced, so no percentage is given.
Hong Kong. Government Rent is 3% of the rateable value, which is the estimated annual rent of land and building, and new leases from 15 July 1997 run 50 years at a premium plus 3% rent. The real capture is the one-off premium at grant, not the annual charge.
Neither is a tax on land value alone. Citing either as a working land value tax is a tax-base error: the base includes the building.
The Closest Anyone Came
One historical case came close, and it was not in the English-speaking world. Kiautschou was the German leasehold on the Shandong coast whose port was Qingdao, administered from 1898 to 1914. Its land and tax statute, written by Wilhelm Schrameier, was, in the words of the American Journal of Economics and Sociology’s 1984 study of it, “inspired by Henry George”. The government bought land at pre-occupation prices and sold it at public auction: buyers paid a 6% land tax on assessed value, a reseller paid one third of the net profit to a government that held a pre-emption right, and if the land was not resold a one-third increment levy fell every 25 years.
What cannot be confirmed is that it levied no other taxes. The sources describe land revenue as central and the port as duty-free, and duty-free is not the same as a single tax. So Kiautschou is the closest historical approach, not a demonstration.
The Verdict
The single tax has never been fully implemented. No jurisdiction identified here has ever funded itself from land value alone. The Economist said as much in February 1998, and that remains the position. It is a magazine’s statement of a widely held view rather than a systematic survey, and is reported as such.
A land tax is not administratively impossible at scale. Estonia has levied a national one since 1993, Denmark a municipal one on a land-only base, Taiwan two, and every Australian state taxes unimproved land value. What it requires is a valuation roll separating land from improvements, and building that is a real cost. A cost is not an impossibility.
Where land taxes have moved, the movement is visible and small. Denmark’s cap went from 34 to 30 per mille and the tax stayed. Estonia’s 2025 bands are narrower for residential land than the old 0.1 to 2.5% range. Capping and rate creep are the documented pattern; outright abandonment is the exception.
Where a land tax has been cut back, the documented cause is political. Ireland in 2012 is the case with the reason written down. Samuels, writing in the American Journal of Economics and Sociology in 2003 on why the Georgist movement did not succeed, attributes it to ideology and organized interest, naming the Catholic Church as a major landowner opposed to the tax. The Pennsylvania record shows ordinary municipal politics doing the same work. This is a story about who can be overruled, not about whether the tax can be administered.
Two claims should be dropped, and one of them is ours. In The Wealth Tax Video That Got Everything Right (Until It Didn’t) we said that land value taxes are politically toxic and administratively difficult at scale, and that every country which has tried a serious land value tax has watered it down or abandoned it. The second half of that sentence does not survive the list above: Denmark, Estonia and Taiwan levy land taxes now, so does every Australian state, and one named counter-example falsifies an “every”. The defensible version is narrower and stronger: no jurisdiction has ever funded itself from land alone.
The second claim to drop is that a land tax can be shown to raise enough to replace other taxes. No such claim was verified, and the pair of Estonian facts belongs together: a major source of municipal funding, and under 1% of total tax revenue.
That leaves the argument where the numbers put it. A land tax has the strongest theoretical case of any tax, a working set of jurisdictions that levy one, a much thinner set that has tried to live on one, and a documented pattern of being capped or repealed by the people who own the land. Whether that is a reason to stop proposing it, or a reason to design it so the losers cannot reach the switch, is the question the evidence leaves open.
Rent is the value a land tax would collect, and capping the rent instead of taxing it is the more common intervention, with the results set out in The Fastest Way to Destroy a City - Except for Bombing. California’s Wealth Tax runs into the opposite constraint: a tax on wealth chases a base that can leave, and land is the one asset that cannot. That is George’s point arriving from a direction he did not have to argue.
