Revises criteria to establish base year for homestead property tax reimbursement after relocation.

This bill revises how the "base year" is determined for New Jersey's homestead property tax reimbursement program when eligible claimants relocate. It specifies that for those who move to a new homestead within the state, the base year becomes the first full tax year prior to the move (instead of the year of relocation), but this rule does not apply to tax years beginning before January 1, 2021. The change directly affects qualifying seniors (65+) or disabled residents with income limits who own or rent a principal residence and seek tax reimbursement after moving. The policy update ensures consistent base year calculations for relocation claims under current eligibility rules.
