Makes total property tax exemption for 100% disabled veterans retroactive to effective date of determination of total disability; requires State to reimburse municipalities for reimbursement of property taxes paid to veteran.

This bill makes property tax exemptions for 100% disabled veterans retroactive to the date the U.S. Department of Veterans Affairs officially determines their total disability. It directly affects veterans with qualifying service-connected disabilities (like paralysis, blindness, or amputations) who previously paid property taxes during the gap between their disability determination and when they applied for the exemption. The key provision requires the state to reimburse municipalities for property taxes paid by veterans during this retroactive period. This changes the existing law to ensure veterans receive tax relief for all eligible periods, not just from the application date forward.
