Property taxes are due in two installments every year. The 1st installment is due sometime in June and the 2nd installment is due sometime in September. Current year taxes are paid to the McHenry County Treasurer's Office. Tax Bills are mailed to "Taxpayer of Record," and not to the lienholder if there is one. Mortgage companies will typically reach out on their own to verify and pay real estate taxes if you have an escrow account setup. Under Illinois Law, your taxes are due and must be paid on time, whether or not you receive a tax bill.

If payment of current taxes has not been received by the McHenry County Treasurer's Office a certified letter will be sent sometime after the 2nd installment due date informing the homeowner of any outstanding balances. Once taxes are sold, a notice prepared by the tax buyer, called a "Take Notice," is mailed by the County Clerk's Office within 4 1/2 months from the date of the Tax Sale. 

It is very important that the County has the correct information for your PIN. You can check the mailing address for the current year by looking up your tax bill on the Treasurer's website.

A notice is also placed on any subsequent tax bills mailed out.
