Progress and Poverty Institute A Philadelphia policy briefing

Tax land more.Tax homes less.

Same revenue. Lower rate on buildings, higher on land.

One property tax, two rates

Today one rate, 1.3998% for the City and School District together, covers land and buildings alike. It has not changed since 2016.2,3 A land value tax splits it: land is taxed at 4 times the building rate, and the two rates are set so the City and School District collect exactly what they collect today, $2.42 billion a year.1

TodayLand value tax Land 1.40% 3.13% Buildings 1.40% 0.78%

Assessments stay the same. What changes is how each property's assessed value is split between land and building, and the rate each part pays. Fixing up a home is taxed at half today's rate.

A rowhouse, and the empty lot next door

Yearly tax billTodayAfterChange
Owner's rowhouse$1,903$1,723−$180
Same house, rented$3,303$2,990−$313
Empty lot, same land$682$1,525+$843

The typical home: $49,000 of land and $187,000 of building (21% land), the medians of 210,208 single-family homes with a Homestead Exemption.1,4 The owner's rowhouse takes the $100,000 Homestead Exemption; the rented one doesn't.5 Both houses save 9%.

The rule of thumb: a property pays less when its land is under about 26% of its value.

The biggest cuts go to poorer and more diverse neighborhoods

Change in homes' total tax bill, by fifths of Philadelphia neighborhoods (census block groups, cut so each fifth holds a fifth of the city's homes). Neighborhood income and race come from the Census Bureau's American Community Survey.6 The poorest fifth are block groups with a median household income under $39,767, the richest over $97,031; the whitest fifth are under 28% non-white, the most non-white over 97%. These are neighborhood averages, not households. Both charts share one scale.

The FHFA column reruns the model with an independent federal estimate of land values: the Federal Housing Finance Agency's land share for each census tract, applied to the single-family houses it covers (96% of them). Condominium units keep the main model's land, because FHFA's shares come from appraisals of houses.7 It points the same way. The gap between the poorest and richest fifths is about half as wide as in the main model. On OPA's current land values, the pattern reverses: the biggest cuts go to richer, whiter neighborhoods.1

Idle land pays more

Outline of Philadelphia with a square 1.5 miles on a side at its center. The square is the combined area of every taxable vacant lot and surface parking lot in the city.

1,470 taxable acres sit vacant or paved for parking: 21,733 taxable vacant lots and surface parking lots (1,145 acres of vacant land and 326 of parking) that together would fill a square 1.5 miles on a side.8,4 A typical such lot would see its tax bill double, so it starts to pay to build, or to sell to someone who will.1

Building-heavy property pays less and land-heavy property pays more: 66% of homes and about half of apartment buildings pay less, while most commercial properties pay more, nearly 9 in 10 warehouses and gas stations among them.1

Some homeowners pay more too. Of homes with a Homestead Exemption, 66% pay less (median saving $277) and 34% pay more (median $449), mostly where land is a big share of value. The Longtime Owner Occupants Program9 and the Senior Citizen Tax Freeze10 continue.

How Philadelphia gets there

Before a vote

Build public understanding

Poll Philadelphians and test how best to explain the shift. Give every owner a way to look up their own property. Publish accurate land values years before any rate changes, so owners see their land and building figures move while their bills don't. Land taxes have been lost this way before. Pittsburgh repealed its split rate in the backlash to a 2001 reassessment,11 and Altoona's council dropped its land tax in 2016 partly because it “caused confusion.”12

  1. 1City Council, now

    Fix land assessments

    Require the Office of Property Assessment to value land accurately, tested against sales; this page's figures use a first version of such values. No state permission is needed, and every figure on this page depends on it.

  2. 2State, in parallel

    Pass enabling legislation

    State law lets third-class cities and boroughs tax land above buildings, but not Philadelphia.13,14 The bill must also fit the Homestead Exemption and other long-running relief to two rates: under today's homestead rule, which takes it off the building first, 64% of exempt homeowners would pay more; with the fix, 34%.15,1

  3. 3City Council, then

    Pass the land value tax

    Shift the rate from buildings to land, revenue-neutral, phased in over 10 years, once land is valued accurately and the city has clear state authority. Restore the full abatement for buildings now on the graduated schedule, and let new abatements glide out over the phase-in.

Pennsylvania has done this for a century

About 20 Pennsylvania municipalities have taxed land above buildings.16,17 Harrisburg (since 1975) and Allentown (since 1997) are among those that still do.17,18,19 Published studies of those cities found:

+14%new homes a month in Pittsburgh from a 5% cut in its building tax rate, the effect Bourassa found; raising the land tax had no significant effect on its own.20
6–8 pointsfaster growth in housing units per square mile over a decade in towns with two rates: denser, less sprawl.21

Those are the published effects, in the cities and years they were measured. PPI's own projection for this plan, below, is deliberately more conservative: applied to this plan's 44% cut in the building rate, the Pittsburgh elasticity would imply several times the homes the model projects.

The 10-year abatement is honored, then glides out

Philadelphia's 10-year abatements take new construction and improvements off the tax bill for a decade.22 Under this plan no abatement ends early, and buildings now on the graduated schedule, whose exempt share falls 10 points a year, get the full 10-year abatement back. While an abatement runs, its owner pays more on the land. Of the 20,233 abated properties, 33% never pay more overall, including 80% of those on the graduated schedule (44% without the restoration); 44% pay more for a time and are made whole after the abatement ends; 23% pay more for good. Once it ends, 76% pay less than under today's tax, a median $780 a year. The last abatement expires in 2036.1

New buildings get the glide. A project starting in 2027, the reform's first year, is fully abated for ten years; each later start year is exempt 10 points less, and projects starting after 2036, when the phase-in is complete, get none, only the lower building rate. The model projects about 6,000 more homes over 20 years than under today's law, about 300 a year, a tenth more than the 2,700 the city now adds each year, and about 1,400 more than ending new abatements when the phase-in starts.1 That figure values the land under a new building as land, as the plan does; OPA today sets it at a fifth of what is built. With OPA's rule kept, the model projects about 4,000, so about 34% of the figure is the change in how new buildings' land is assessed.1

Everyone else pays for the abatements, as they do today. The glide's abatements shift about $129 million onto other bills through 2045, less than keeping today's graduated abatement alongside the phase-in would ($197 million). Restoring the graduated buildings' full abatement shifts $29 million more through 2035, raising other bills by at most 0.2%.1

This is the reform phased in over 10 years from tax year 2027. The homes are a projection. Their direction holds in every run of the model, but their number rests on how developers discount future taxes and how widely projects' prospects vary: those runs put it between 3,000 and 12,000, and the model's full sensitivity runs reach wider than that. Today's law means the graduated abatement for every new project and OPA's land rule on new buildings, with building held at the pace of 2023–2025 permits.

A Philadelphia idea

Pennsylvania state historical marker for Henry George. It says he urged taxing socially produced land values instead of individually produced labor and capital.

Land gets its value from all of us: the transit, schools, jobs and neighbors around it. A building gets its value from the people who build it and keep it up.

Henry George, who made that case, was born at 413 S. 10th St. in 1839. The state marker outside reads:23

Tax socially produced land values, he urged, instead of individually produced labor and capital.

How the numbers are made

Every figure on this page is a modeled estimate for tax year 2026, not a tax bill. They come from PPI's Philadelphia model, built on LVTShift, an open-source toolkit that recomputes the bill for every taxable parcel in the city.28 Every figure on this page is published with it as data.1

The records
The Office of Property Assessment's tax year 2026 roll: one row per parcel, with its taxable land and building, property type, lot size and Homestead Exemption.4 "Homes" are taxable 1–4-unit residential parcels with a tax bill today (482,976 of them). Owner-occupied homes, those with a Homestead Exemption or an individual owner whose mailing address is the home, pay less about as often as homes overall (66% of them), but as a group they pay about the same as today (−0.8%): the increases on land-heavy homes offset the majority's savings.1
Land values from land sales
OPA's land values sit close to a fixed share of each property's value. The model replaces them with PPI's own estimates from 3,666 Philadelphia land sales since 2020: lots sold vacant, whether still empty or built on since, and teardowns. Each lot takes the weighted median price per square foot of its ten nearest such sales, each adjusted to the lot's size and to the valuation date; the size adjustment is measured from pairs of nearby sales. On lots larger than 10,000 square feet, which few land sales test, the estimate runs high, so it is scaled down by how far it overshoots the sales of such lots, by lot size. Bare tracts with a restricted use, such as rail corridors and port terminals, keep OPA's value (see the largest lots, below).1
Assessments stay put
For a parcel with a building, land becomes the sales-based estimate (capped at the parcel's total) and the building is the rest. The total assessment does not move, so nobody's assessment goes up; 100% of the 515,731 built parcels keep exactly today's total. Bare lots, having no building to hold a total against, are valued at their land estimate (30,583 of them).
Revenue-neutral rates
With land taxed at 4 times the building rate, the building rate is the one that raises today's revenue:
building rate = revenue ÷ (4 × taxable land + taxable building)
and the land rate is 4 times that: 3.13% and 0.78%.
Other long-running relief
Some properties carry other relief that OPA records as an exemption. It has run since 2015 or earlier and rises with each reassessment, so it is not a construction abatement, and OPA's data does not name its program. How it should divide between land and building under two rates is not set by law. These figures keep it and take it off land and building in proportion to value, like the homestead.1
The Homestead Exemption
At one rate it does not matter which part of a home the $100,000 exemption comes off. Under two rates it does. State law takes it off the building first,15 which would cut the median homeowner's exemption from $1,400 a year to $742, about half. This page's figures take it off land and building in proportion to their value, which keeps most of its worth ($1,251) and needs § 8583(c) amended.1
After today's abatements
The figures describe the city after today's 10-year abatements have run out, with each abated building back on the roll. The transition while they run is modeled year by year in the abatement section.
New homes under the plan
PPI's housing supply model tests, for every parcel that may hold housing, whether building what its zoning allows is worth more than keeping it as it is, after construction costs and taxes, with each project's price allowed to scatter around the neighborhood's. It is fitted to where residential permits were filed in 2023–2025, under today's graduated abatement. Each start year is priced on the phase-in's rates from that year on and the abatement it would get, against today's law. The count is net of the homes a redevelopment replaces.1
The largest lots
The land sales are mostly small lots, so for lots larger than 10,000 square feet the estimate is an extrapolation, and on the sales of such lots that exist it runs high: about 1.17 times the price up to an acre and 1.88 times above. The figures here divide it by that. In these figures homes' total saving is $39 million a year, and most of it goes to homes that are not owner-occupied, mostly rented: they save $31 million (5.0%). Owner-occupied homes as a group pay about the same as today (−0.8%), though 66% of them pay less. Other defensible readings of the largest lots move homes' total saving from $32 million to $68 million. The share of homes paying less barely moves. The table varies only the 1,653 bare lots larger than 10,000 square feet.
