The Henry George Foundation's Response to the TPA/Neidle LVT Model: A Hybrid Land Value Tax with Statutory Building Charge

Summary

In July 2026, the Henry George Foundation (UK) published "Land Value Tax in Practice — Grounds for Cautious Optimism?" — a substantive, sympathetic-but-critical response to Dan Neidle's Tax Policy Associates (TPA) modelling of a UK residential land value tax, the report already covered on this wiki via its coverage on the Andy Burnham page. Where Neidle's report models a specific, revenue-neutral LVT replacing council tax and stamp duty and finds sharp regional winners and losers, the Foundation's response accepts much of Neidle's diagnosis but argues his design choices — particularly strict revenue neutrality and a pure land-only base — make the transition harder than it needs to be, and proposes an alternative design.

Points of Agreement

The Foundation credits Neidle's report with getting several implementation questions right: the need for a transitional mechanism to soften sudden bill increases, a roughly 10-year phase-in as politically necessary, an SDLT credit for people who recently paid stamp duty, and deferral options for elderly, asset-rich homeowners — all mechanisms this wiki's asset-rich, cash-poor objection page already treats as the standard answer to the "little old lady" problem.

The Foundation's Critique

Three points of departure from Neidle's model:

1. Revenue neutrality is the wrong constraint. The Foundation argues that "taxing income from land makes more economic sense than taxing income from other sources," and that the UK's fiscal position may justify using a residential LVT to raise additional revenue — earmarked for income tax or National Insurance Contribution cuts — rather than holding the reform to a strict swap for existing property taxes.
2. Neidle's account of what's broken about council tax is incomplete. The Foundation contends the most economically damaging feature of the current system is not simply that it is regressive or based on stale 1991 valuations, but that it leaves the bulk of land value in private hands rather than capturing it for public benefit — the core unearned increment argument, applied as a critique of the status quo Neidle's own reform proposal does not go far enough to fix.
3. A single-instrument reform (replace council tax and SDLT at once) may be politically riskier than staging it. The Foundation sketches three revenue-allocation options — replacing SDLT and funding the social-care portion of council tax with LVT revenue (Option 1); replacing SDLT while cutting employer National Insurance Contributions in labour-intensive sectors like hospitality and social care (Option 2); or combining both with a partial council-tax cut (Option 3) — as more tractable staging points than a single big-bang swap.

The Hybrid Design: Land Value Tax with a Statutory Building Charge

The Foundation's central proposal responds to what it calls the "valuation paradox": "Land valuation is accurate in theory but difficult to verify in practice, because while it can be done from the desktop... it cannot be checked against a real market transaction." Its answer is a hybrid instrument combining:

• Market-based land valuation — a desktop assessment using location, planning status, and local amenities, the same approach Welsh Government valuation testing is scoping.
• Formula-based building assessment — a statutory charge computed from objective, non-contestable characteristics (floor area, age, building type) rather than a subjective appraisal of the building's market value.

The Foundation argues this hybrid moderates the regional disparities a pure land value tax produces — the same north-south capitalization swing Neidle's modelling finds (sharp falls in London-area property values, rises in cheaper regions) — while eliminating the subjective building-valuation step that is the weakest link in a pure LVT's administrability. Its own framing is candid about the tradeoff: "proponents of LVT should remain flexible on the question of the precise form of tax that is to be introduced," preferring "a gradual, but steady and, above all, patient, roll-out" over the cleanest theoretical design.

Relation to the Georgist Case

This is a useful counterpoint to keep alongside the TPA/Neidle model already on the wiki: it comes from an explicitly Georgist advocacy organization rather than a nonpartisan tax think tank, so its policy conclusions (raise more revenue from land, don't insist on strict neutrality) should be read as advocacy — but its design critique is a genuine, substantive engineering argument about a real tension in LVT implementation: a building-value component computed by formula rather than appraisal trades some theoretical purity (a formula-based charge is not a pure land value tax) for administrability (no subjective building appraisal to contest or corrupt), which speaks directly to the assessment-accuracy objection. Whether a "statutory building charge" retains LVT's efficiency properties depends on how closely the formula tracks actual building value — a question the Foundation's piece raises but does not resolve empirically.

Bears On

• Research: Tax Policy Associates: What Would a Land Value Tax Actually Do? — the model this piece directly responds to; read together for the pure-LVT-vs-hybrid design debate.
• Objection: Land value can't be assessed accurately — the hybrid design is a direct, if untested, response to the administrability half of this objection.
• Objection: LVT hurts the 'asset-rich, cash-poor' — the Foundation endorses the same deferral/phase-in mechanisms this page already documents.
• Person: Andy Burnham — the UK political context (Burnham's premiership and LVT advocacy) both this piece and the TPA model are responding to.
