Forest Park's Property Tax Rate Almost Matches Oak Park's. Here's Why the Bill Doesn't.

How can two towns three miles apart charge almost the same property tax rate, yet one homeowner ends up paying less than half of what the other pays every year? That is the question anyone comparing Forest Park to Oak Park runs into the moment they look past the percentage sign and toward the actual bill.

If you are cross-shopping these two near-west suburbs, you have probably already seen the tax rate comparisons on the usual sites. They look close enough to call it a wash. It isn't. The gap between what a Forest Park homeowner pays each year and what an Oak Park homeowner pays is one of the more consistently underestimated numbers in this corner of the market, and it traces back to something almost nobody mentions in a listing: how much of Forest Park's land doesn't pay property tax at all.

The rate that looks like a tie

Based on Cook County tax bill data compiled by Ownwell, Forest Park's median effective property tax rate sits at 2.99 percent. Oak Park's sits at 3.04 percent. Five hundredths of a percentage point apart. On paper, that is close enough that a buyer skimming two listings might reasonably assume the tax line item will land in the same neighborhood too.

It doesn't.

The rate is nearly identical. The bill is not close. Oak Park's median tax bill runs about $6,400 a year higher than Forest Park's, and the reason has nothing to do with the rate itself. It's the base the rate gets applied to. A near-equal percentage of a much smaller number produces a much smaller bill. Current listing activity backs up the scale of that gap even more: Forest Park's median asking price ran near $325,000 in August 2026, still well under Oak Park's home values, so the price difference driving this math isn't a snapshot from a stale dataset. It's the market right now.

For a buyer, that means the tax rate is close to irrelevant as a comparison point between these two towns. The number that actually predicts your monthly payment is the price of the house, not the percentage printed next to it.

Half the village doesn't pay a dime

Here is the part that explains why Forest Park's rate is elevated at all, given how modest its home values are. According to Forest Park's own 2014 Comprehensive Plan, reported by the Forest Park Review, cemeteries are the predominant land use in the village, anchoring its west and south sides. The plan puts the figure at roughly 40 to 45 percent of the village's total land area.

That is not a rounding error. That is close to half the town.

Forest Home Cemetery, which absorbed the adjacent German Waldheim Cemetery in a merger in the late 1960s, sits along the Des Plaines River and borders the Eisenhower Expressway. Concordia Cemetery, the first in the village to hold a consecrated burial, sits nearby. Woodlawn Memorial Cemetery, home to the roughly 750 burial plots known as Showmen's Rest for circus performers killed in a historic train wreck, adds still more acreage. Altenheim rounds out the list. Illinois law exempts land used exclusively for burial from property tax, the same exemption that applies to cemeteries statewide, so none of that land shows up on the village's tax rolls in any meaningful way.

That has a direct mechanical consequence. When a large share of a town's footprint contributes nothing to the tax base, the remaining taxable parcels, mostly homes and a modest commercial strip, have to cover the whole cost of running the village. Fewer taxable acres spreading the same fixed costs of police, fire, schools, and streets pushes the rate up on everyone who is left paying. That is the mechanism holding Forest Park's rate close to Oak Park's even though Forest Park's homes are worth a fraction of Oak Park's. It isn't that Forest Park's government spends like Oak Park's. It's that a smaller taxable base has to carry the load on its own.

The commercial corridor isn't picking up the slack either

A thin tax base usually gets some relief from commercial property, but Forest Park's Madison Street and Roosevelt Road corridors have had their own churn. In a 2025 accounting by the Forest Park Review of storefronts on the market along those two streets, several long-running businesses were in transition at once. Brown Cow Ice Cream Parlor's owner, Connie Brown, put the building and business up for sale, citing a mortgage up for renewal and three children now grown into adults. Shanahan's, a Madison Street fixture for 35 years, was possibly changing hands. McGaffer's Saloon on Roosevelt Road had closed indefinitely after its owner, Pat Malone, was injured in a fall at the bar. ABC Automotive and Electronics was in the process of relocating out of its Roosevelt Road storefront to a larger space built for upfitting police squad cars.

None of that is unusual for a small commercial strip working through ordinary turnover, and some of those situations may well have resolved by now. But it illustrates the point: Forest Park's commercial tax base is not deep enough to absorb the shortfall left by nearly half the village sitting on tax-exempt cemetery ground. The village has responded by leaning on tax increment financing, with a Roosevelt Road Corridor TIF district and others directing new development's tax growth back into the corridor rather than the general fund. That is a tool for building the base over time. It is not a substitute for having one now.

What the gap actually buys you

Translate the two bills into monthly terms and the comparison gets concrete fast. Forest Park's median annual tax bill of $4,646 works out to about $387 a month. Oak Park's median annual bill of $11,084 works out to about $924 a month. That's a difference of roughly $537 every month, purely in property tax, before either homeowner has made a mortgage payment.

For a buyer weighing a move from the city or comparing near-west suburbs against each other, that monthly gap can be the difference between qualifying for a slightly larger mortgage or not. It also means a lower-priced Forest Park home is not just cheaper on the sticker price. It is cheaper in a way that compounds every year the tax rate stays close to where it sits today, since the smaller price base keeps multiplying against a similar percentage indefinitely.

None of this means Forest Park is automatically the better financial choice or that Oak Park is overpriced for what it delivers. It means the tax rate, the number most comparison tools lead with, tells you almost nothing about what you'll actually owe each year. The bill does. And the bill is driven by a structural fact about the village's land, not by anything printed on a listing sheet.

A couple of questions worth asking before you assume Forest Park is "the cheap one"

Does a lower tax bill mean Forest Park gets less in services? Not necessarily. The gap here traces to the size of the taxable base, not to a decision to spend less. A smaller base times a similar rate produces a smaller bill regardless of what the village funds with it. If service levels matter to your decision, that's a separate conversation worth having block by block, not something you can infer from the tax bill alone.

Is the 40 to 45 percent cemetery figure still accurate, given the plan is from 2014? Cemetery land doesn't get redeveloped or rezoned in the way commercial or residential parcels do, so the underlying share of the village's footprint tied up in burial grounds has almost certainly held steady since that plan was written. The document is over a decade old. The land use it describes isn't the kind that changes on that timeline.
