How are Kendall County property taxes paid?

The Kendall County Treasurer and Collector, at 504 S. Main Street in Yorkville, (630) 553-4124, bills taxes in two installments. For 2026 the Treasurer’s paying taxes page lists September 9, 2026 for the second installment, and the county announced June 9 for the first. The Treasurer says estimated or partial payments aren’t accepted: you pay the exact installment amount or the whole bill.

What happens if I pay late?

The Treasurer’s paying taxes page says anything postmarked after a due date is charged a penalty of 1.5% of the installment amount per month. Banks may take payments after the first due date at their discretion, but the Treasurer says banks can’t accept any payment after the second due date, so late payments go to the Collector’s office.

When is the Kendall County tax sale?

Unpaid taxes can be offered at the county’s annual tax sale, run by the Treasurer. The sale is usually held in the fall. The county also has a single bidder ordinance (22-13), listed on the same tax sale page. If the taxes are sold, the house isn’t sold; a buyer pays the taxes and gets a certificate against the property.

Who handles redemption after a sale?

The County Clerk, not the Treasurer. The Kendall County Clerk and Recorder is at 502 S. Main Street in Yorkville; the Clerk’s line is (630) 553-4104 and the Recorder’s is (630) 553-4112. The notice set out in 35 ILCS 200/22-5 tells owners to contact the County Clerk for the redemption deadline and the exact amount, and says most residential property with fewer than 6 units has a redemption period of 2 1/2 years from the date of sale, which can be extended. Confirm your own deadline with the Clerk.

Can I sell the house if I’m behind on taxes?

Yes. Unpaid or sold taxes are a lien on the house, and a title search will show them. At closing, the title company typically pays what’s owed from the sale proceeds. We explain every cost up front, before you sign anything, including how the tax payoff shows up on the closing statement. We can often cover closing costs.

What if I want to keep the house?

Call the Treasurer at (630) 553-4124 before the sale, or the County Clerk at (630) 553-4104 after it, and ask for the exact amount. A HUD-approved housing counselor, which you can find through the CFPB counselor search, can help you look at options at no cost to you. Talk to an Illinois attorney if a tax deed notice has arrived.

Should I sell to you or list with an agent?

Here’s an honest comparison:

Listing usually wins when the house is in good shape, you have time, and you want the highest possible price.
Selling to us may fit when the house needs work you don’t want to do, you’re behind on payments, or you need a set closing date.
Costs. Selling directly to us means you don’t list with an agent, and we can often cover closing costs. We explain every cost up front, before you sign anything.

If listing is the better choice for your house, I’ll tell you.

What if selling is the cleaner path?

You don’t have to fix anything first.

We buy as-is: no showings, no repairs needed. Selling directly to us means you don’t list with an agent.

We can often cover closing costs. We explain every cost up front, before you sign anything.

How do you check out any cash buyer before you sign?

Get the offer in writing. It should show the price and who pays which costs.
Read the whole contract. Ask about any line you don’t understand before you sign.
Have your own attorney. An Illinois real estate attorney can review the contract for you.
Check that the business is registered. You can look it up on the Illinois Secretary of State business search.
Don’t pay upfront fees. You shouldn’t have to pay anyone just to sell your house.
Ask about your right to cancel. Illinois law gives owners behind on a mortgage or taxes extra protections in some sales. An attorney can tell you what applies to you.

This is general information, not legal advice. Talk to an Illinois attorney about your situation.
