Local Government, General - As introduced, requires that a reduction of the allocations and distributions of certain tax and other revenues to counties and municipalities due to a population loss based on the revised populations certified by the department of economic and community development be implemented incrementally in 20 percent increments over a five-year period. - Amends TCA Title 4, Chapter 3; Title 4, Chapter 49; Section 9-16-101; Title 54, Chapter 4; Title 55, Chapter 4; Title 57, Chapter 5, Part 2; Title 57, Chapter 3, Part 3 and Title 67.

HB 2182 requires Tennessee counties and municipalities to phase in funding reductions from population declines over five years instead of implementing them all at once. The bill mandates that the first year's cut cannot exceed 20% of the total projected loss, with additional 20% increments applied each subsequent year until full adjustment aligns with revised population data. This applies to annual revenue allocations based on population certifications from the Department of Economic and Community Development. If a jurisdiction's population increases during the phase-in period, the reduction schedule recalculates accordingly.
