Revising the disabled veteran property tax assistance program

This bill updates Montana's disabled veteran property tax assistance program to include veterans rated between 60% and 90% disabled, in addition to those rated 100% disabled. It establishes income-based tax rate reductions for eligible veterans and their spouses, with higher assistance percentages for those with higher disability ratings. The legislation also introduces annual verification requirements to confirm eligibility each year based on income, disability status, and residency. These changes apply immediately and affect property tax calculations for qualifying veterans and surviving spouses in Montana.
