Establishes a real property tax exemption for widows and widowers of police officers killed in the line of duty

This bill creates a real estate tax exemption for the primary homes of widows and widowers whose spouses were police officers killed in the line of duty. Under the new rules, eligible survivors can receive a fifty percent reduction on their property taxes, though local governments or school districts retain the authority to lower this percentage if they choose. The law defines eligible police officers using existing state definitions and includes specific provisions for cooperative apartment residents, while also establishing a standardized list of documents to prove eligibility. The exemption applies to properties owned directly by the survivor or held in trust for their benefit, and it becomes effective on the first day of January following its passage.
