What Happens If You Don’t Pay Property Taxes in Cook County?

Cook County has some of the highest effective property tax rates in the nation, and it’s not uncommon for homeowners to fall behind. But unpaid property taxes in Cook County don’t just disappear — they trigger a process that can eventually cost you your home.

Here’s what happens step by step, and what you can do about it.

The Cook County Tax Delinquency Timeline

Year 1: Penalties and Interest

When you miss a property tax payment in Cook County, the county begins adding penalties at 1.5% per month. This adds up fast — after 12 months, you owe an additional 18% on top of the original tax amount.

Year 1-2: Annual Tax Sale

Cook County holds an annual tax sale, typically 13-14 months after the taxes were originally due. At this sale, investors purchase the delinquent taxes (not the property itself). The tax buyer pays your delinquent taxes and receives a certificate entitling them to the taxes plus penalties.

Years 2-5: Redemption Period

After the tax sale, you have a redemption period — typically 2 to 2.5 years for residential property — to pay back the tax buyer the amount they paid plus substantial penalties (which increase every 6 months). During this time, you still own the property, but the clock is ticking.

After Redemption Period: Tax Deed Petition

If you don’t redeem within the redemption period, the tax buyer can petition the court for a tax deed, which transfers ownership of the property to them. At this point, you lose the property entirely.

The Scavenger Sale

Every two years, Cook County also holds a scavenger sale for properties with taxes delinquent for two or more years. At scavenger sales, properties often sell for far less than the amount owed, and the redemption terms are even steeper.

What Are Your Options?

If you’re behind on property taxes, you have several options. You can enter a payment plan with the Cook County Treasurer’s office to catch up on delinquent taxes over time. You can apply for exemptions you may have missed, like the Senior Citizen or Homeowner exemptions, which can significantly reduce your tax bill going forward. Or you can sell the property and use the proceeds to clear the tax debt.
