Tax bills are typically mailed in October or November, with a December 20 deadline for the full amount or an option to pay in two installments. Idaho offers a meaningful homeowner exemption that exempts half of a home's value from taxation (up to a cap), making it one of the more generous homeowner exemptions in the western United States.

You may pay in two equal installments: First installment: Due December 20 Second installment: Due June 20 of the following year Paying by the first installment date is also an option for paying in full.
