Property tax due dates by county

When are property taxes due? All counties at a glance

Most counties bill once a year in the fall and give you until a delinquency date, while some split the bill into two installments. Paying after the delinquency date adds penalties and interest set by state law. The table lists every date we track, from each county's tax office.

What happens if you pay late

Late payment adds a penalty and monthly interest set by state law, and unpaid taxes become a lien on the home that can eventually be sold at a tax sale. The penalty column above shows the rule for each county where the office publishes it; Cook County, for example, holds its annual tax sale for tax year 2023 delinquencies on December 15, 2026.^[2]

• Mortgage escrow: if your lender pays from escrow, check that the payment posted; you are still liable if it did not.
• Postmarks: most offices accept a payment postmarked by the due date, but online payments are dated when submitted.
• Seniors and disabled owners: several states allow deferral or installment plans; see property tax exemptions for seniors.
