Property Tax Reduction Program

If you are a qualified Idaho homeowner, you may be eligible for the Property Tax Reduction program. This program may reduce property taxes on your home and up to one acre of land by as much as $1,500. The Idaho State Tax Commission administers the Property Tax Reduction program, but you must apply through the county assessor’s office (I.C. 63-703).  Applications must be received between January 1 and April 15*.  For newly constructed dwellings, the deadline to apply for the Property Tax Reduction program is within 30 days of receiving your notice of occupancy with your assessment notice.  Guidelines and filing procedures are outlined in the Idaho Property Tax Reduction Program brochure.  To learn more about the Property Tax Reduction program please refer to our Property Tax Reduction Story Map.

Please Note:  Property Tax reduction benefits will not reduce solid waste, irrigation or other fees or certifications charged by government entities.
