Clarendon Hills Property Taxes: What You’ll Actually Pay (2026)

Clarendon Hills sits in DuPage County, which keeps its tax math simpler than the Cook County villages right next door (like Western Springs and La Grange). Here’s the honest version: the real effective rate, how the bill is built, how it stacks up against Hinsdale, and the exemptions that bring it down.

The real effective rate

In Clarendon Hills, the effective property tax rate runs about 1.96% of a home’s value (per Ownwell, 2026), with a median annual bill around $10,200. That’s actually below the DuPage County average (~2.16%) and well under the Illinois statewide median (~2.33%).

How it compares to the immediate neighbors:

So Clarendon Hills lands in a reasonable middle: a touch above some Hinsdale estimates, but generally below the Cook County villages a few minutes east. Combined with lower home prices than Hinsdale, the total bill on a comparable home is often friendlier here.

What you’ll actually pay (estimate)

Applying the ~1.96% effective rate to market value (a ballpark, before exemptions):

• A $700,000 home: roughly $13,700 a year
• A $1,000,000 home: roughly $19,600 a year

Treat these as estimates. The real number depends on the exact parcel’s overlapping taxing districts and the exemptions claimed. Pull the specific PIN from the DuPage County Treasurer for an exact figure.

How DuPage builds the bill

• Residential property is assessed at one-third (33.33%) of fair market value, then the state applies an equalization factor to standardize across counties (per the DuPage tax mechanics).
• The composite rate of all your overlapping districts (village, schools, county, township, park, library, fire) is applied to the equalized assessed value, minus exemptions, to produce the bill.

The exemptions to claim

These come straight off your equalized assessed value:

• General Homestead Exemption: up to an $8,000 reduction for an owner-occupied primary residence (per DuPage County). File it the year you close.
• Senior Citizens Homestead Exemption: an additional $8,000 reduction for owners 65 and up, which stacks with the General Homestead.
• A Senior Freeze is available for income-qualified seniors.

What it means for you

• Budget around 2% of the purchase price per year as a starting estimate, then refine with the actual parcel.
• The day you close, make sure the General Homestead Exemption is filed in your name.
• When comparing to Hinsdale or to the Cook County villages, remember Clarendon Hills’ lower home prices often make the total bill more manageable for the same schools.

The bottom line

Clarendon Hills taxes are knowable and middle-of-the-road for the area: roughly 1.96% effective, on the simpler DuPage system, below the county average. Paired with home prices below Hinsdale’s, that’s part of why the village is such a value for families. Pull the specific parcel, confirm the exemptions, and compare the real total before you decide.
