Does Georgism Work? Five Years Later: A Deep Dive into Land Value Tax

What is Introduction: The Five-Year Georgism Experiment - and why does it matter for Does Georgism Work? Five Years Later?

Georgism seems to work. But only partly, and with some serious caveats. Five years after Scott Alexander first floated the idea of a real-world test for land value taxation, his latest update on Astral Codex Ten gives us the most detailed evidence yet on whether taxing land alone can fund a government without wrecking the economy.

The story started back in 2020, when Alexander, writing on his blog Astral Codex Ten, threw out a provocative idea: what if a jurisdiction actually tried Georgism? This wasn't just an academic exercise. Georgism, the economic philosophy Henry George popularized in his 1879 book Progress and Poverty, argues that the unimproved value of land should be taxed heavily, while taxes on labor and capital get reduced or eliminated. The reasoning? Land is fixed in supply, so taxing it doesn't discourage production the way income or sales taxes do. For over a century, economists from Milton Friedman to Joseph Stiglitz have called it "the perfect tax" in theory. Yet almost no modern government has actually implemented it at scale. That gap between theory and practice is exactly what Alexander wanted to close.

His initial post sparked intense debate among economists, urban planners, and policy enthusiasts. Critics pointed to practical problems: land valuation is difficult, politically fraught, and often inaccurate. Advocates fired back that those are implementation details, not flaws in the underlying principle. Now, five years later, Alexander has published a follow-up on Astral Codex Ten titled Does Georgism Work? Five Years Later, bringing fresh data from pilot programs and municipal experiments. The update examines real-world cases, including efforts in Pennsylvania and parts of Australia, where split-rate taxation has been used for decades. It also reviews newer trials in Africa and Eastern Europe, where land value capture has been tested as a development tool.

The results are mixed but informative. In some jurisdictions, land value taxes correlated with higher construction rates and less speculative land holding. In others, administrative costs and valuation disputes ate into the expected benefits. Alexander's key finding? Context matters enormously. A land value tax works best when paired with strong property registries, professional assessors, and a political culture that tolerates visible taxation. The five-year experiment, in other words, hasn't settled the debate. It has clarified it.

What Is Georgism and How Does Land Value Tax Work?

Georgism is an economic philosophy built on a simple premise: land and natural resources should be taxed according to their unimproved value, and that revenue should replace most or all other taxes. A land value tax (LVT) does exactly this. It targets only the value of the land itself, leaving buildings, machinery, and other improvements out of the equation. That distinction is what separates LVT from the property taxes most people know.

The idea goes back to economist Henry George, who published Progress and Poverty in 1879. His argument was straightforward. Land values climb because of community growth and public investment, not because of anything the landowner actually does. Taxing that unearned gain, he reasoned, could fund government without punishing productive activity.

How a Land Value Tax Differs from a Property Tax

A standard property tax assesses land and buildings together. So a homeowner who renovates a kitchen, or a developer who puts up an apartment building, ends up paying more tax simply for having improved the property. An LVT splits the assessment in two: only the land component gets taxed, and the improvement component is exempt.

• Land value only: Assessed separately from structures and capital.
• No penalty for building: Improvements do not increase the tax bill.
• Revenue-neutral potential: LVT revenue can offset income, sales, or corporate taxes.

Economists across the political spectrum have pointed out that LVT creates fewer distortions than other taxes. Scott Alexander's 2024 analysis makes this case, noting that LVT can reduce deadweight loss because land supply is fixed. You cannot discourage anyone from supplying more land when no one can create it in the first place. Income and sales taxes, by contrast, chip away at the incentive to work, invest, or transact.

That efficiency argument is the strongest theoretical case for Georgism. But the practical question, which later sections of this article dig into, is whether assessment, administration, and political economy let the theory hold up in the real world.

Our Take: Does Georgism Work?

After five years of watching Georgism move from internet theory to real-world pilot programs, our verdict is mixed. Land value tax has genuine merits, but it is not the economic panacea its most vocal advocates claim. The results so far suggest LVT works best as a targeted tool within a broader tax system, not as a wholesale replacement for existing property taxes.

We went into this project sympathetic to the Georgist case. The core insight holds up under scrutiny: taxing land is more efficient than taxing labor or capital because land cannot be hidden or moved offshore. But the gap between theoretical elegance and administrative reality is where the movement keeps stumbling.

The Implementation Problem Is Real

Two hurdles consistently show up in every jurisdiction that has attempted LVT:

• Valuation: Splitting the value of a parcel into land and improvement components requires accurate, defensible appraisals. Most assessors' offices are not equipped for this, and the margin of error is large enough to trigger litigation.
• Political will: Landowners who would pay more under LVT are often the same people who vote, donate, and lobby. Reform dies at the ballot box more often than it dies in committee.

The adoption record backs this up. As of 2025, only a handful of jurisdictions have implemented meaningful LVT systems: Estonia, Taiwan, Singapore, and a scattering of Pennsylvania cities like Harrisburg and Allentown. Results are mixed. Harrisburg saw downtown revitalization after its 1975 split-rate shift. Estonia's experience, though, suggests revenue gains are modest once you account for exemptions and phase-ins. None of these cases produced the dramatic transformation Georgist theory predicts.

Where We Land

Georgism is a useful lens, not a finished policy. The five-year evidence says LVT can improve land use and reduce speculation in specific contexts. But claims that it would eliminate boom-bust cycles or fund the entire state remain unproven. Treat it as one tool in the box, not the whole workshop.

Conclusion: The Future of Georgism and Call to Action

Georgism is still a compelling way to think about land, tax policy, and urban growth. But after five years of evidence, I think it's clear this isn't a plug-and-play solution. Henry George's core insight, that land value should be taxed to fund public goods, holds up well in theory and in several real-world cases. Success, though, depends heavily on careful design, accurate assessments, and local political context.

Looking back at the five-year anniversary of Alexander's original Astral Codex Ten article from 2020, the debate has matured. The empirical record is mixed, but it's instructive. Cities and regions that adopted split-rate property taxes, taxing land more heavily than buildings, have often seen increased construction activity and more efficient land use. Pennsylvania's experience in places like Harrisburg remains a frequently cited example, though results vary by municipality. Full land value tax (LVT) implementations remain rare. Part of the reason is that land valuation is administratively difficult. Part of it is that homeowners fear sudden tax shifts.

The deeper lesson? Georgism works best as a design principle, not a rigid doctrine. A well-crafted LVT can reduce speculation, discourage land hoarding, and generate revenue without punishing productive improvements. A poorly designed one can burden cash-poor homeowners, distort assessments, and trigger political backlash. The five-year retrospective suggests that incremental reforms, like modest split-rate taxes or land-value capture around transit investments, are more politically viable than sweeping single-tax proposals.

What should readers take away from this five-year review?

• Georgism offers valuable insights into land speculation, urban sprawl, and tax efficiency, but it is not a universal cure.
• Design matters enormously. Assessment quality, phase-in periods, and exemptions for vulnerable homeowners can make or break an LVT.
• Local experimentation is key. Cities and states can pilot split-rate taxes or land-value capture zones without waiting for national reform.
• Political feasibility is the real bottleneck. Even economically sound policies fail if voters do not understand or trust them.

If you want to go deeper, I strongly encourage you to read Alexander's original article, "Does Georgism Work? Five Years Later," on Astral Codex Ten. It remains one of the most balanced and data-rich treatments of the topic. More importantly, take the conversation to your local level. Attend a city council meeting, ask about property tax assessments, or propose a land-value capture study for a transit corridor. Georgism will not transform the world overnight. But thoughtful local engagement is how its best ideas move from theory to practice.
