Property Taxes in Illinois: What Every Home Buyer and Seller in Naperville, Aurora, Oswego, and Plainfield Should Know
Nobody loves talking about property taxes. But if you're buying or selling a home in Illinois, they might be the most important number you're not looking at closely enough. Illinois has some of the highest property tax rates in the country, and here in the western suburbs, the differences from one street to the next can be significant.
How Property Taxes Work in Illinois
In Illinois, property taxes fund local services including schools, the county, the city or village, and park districts. The school district alone typically accounts for about 70 percent of your total tax bill. That's why two homes that are half a mile apart can have very different tax bills if they fall in different school districts.
Our area spans DuPage County and Will County. Both counties have their own assessment and taxing structures. Buyers who move here from other states are often surprised by how much Illinois property taxes add to a monthly housing payment. This is not a scare tactic. It's something we walk every buyer through before they make an offer.
Illinois carries one of the highest average effective property tax rates in the country. That's a fact worth building into your budget from day one.
What to Know By City
In Naperville, median sale prices are around $665,000 and the tax bills reflect those values. The City of Naperville also charges a real estate transfer tax of $1.50 per $500 of the sale price. Keep that in mind when you're calculating closing costs.
In Aurora, the median effective property tax rate is around 3.06 percent, which is above the Illinois state median of 2.33 percent. The City of Aurora charges a transfer tax of $3 per $1,000 of value, typically paid by the seller but sometimes negotiated. All city accounts must be paid in full before a transfer stamp is issued.
In Oswego, the Village charges a real estate transfer tax of $3 per $1,000 of the sale price, paid by the buyer. If you've lived in your Oswego home for at least 12 months and you're buying a new primary home in Oswego, you may be exempt from that fee. Median prices in Oswego are around $400,000.
In Plainfield, if your property is incorporated within the Village of Plainfield, there is generally no municipal transfer tax. But some properties with a Plainfield mailing address fall under different village limits, so always confirm with the specific municipality. This is one of those details that trips people up, and it's exactly the kind of thing we check on every transaction.
What This Means When You're Buying
Before you make an offer, ask for the current property tax history on the home. Ask about any pending reassessments. Understand which school district the property falls in and verify it directly because online listing data is sometimes wrong about school boundaries.
We use a tool called RealReports on every home we evaluate with clients. It pulls data from more than 30 sources and includes tax history, flood zone info, permit history, and more. It's not something most buyers know to ask for, but we build it into our process because it protects you.
You can start your search now on Zenlist, which gives you real-time MLS access so you can see homes the moment they come available.
What Sellers Should Keep in Mind
Your property tax history is something buyers will look at closely. If your taxes are significantly higher than comparable homes nearby, it can affect your price or buyer pool. We help sellers understand this dynamic as part of our pricing strategy process.

How do I find out what the property taxes are on a home I'm interested in near me?
