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

This bill changes how the "base year" is calculated for New Jersey homeowners who relocate and qualify for homestead property tax reimbursements. It revises the rule so that when an eligible homeowner moves to a new primary residence, their base year (used to calculate tax refunds) becomes the first full tax year before the move - **but only for tax years starting on or after January 1, 2010**. This affects elderly or disabled homeowners who move within the state and meet income and residency requirements. The key change prevents the new base year rule from applying to tax years before 2010, maintaining the prior calculation for earlier relocations.
