Taxes, Real Property - As enacted, establishes the process for property tax assessment and valuation of multi-unit rental housing that receives a federal, state, or local incentive based on low-income renter restrictions. - Amends TCA Title 7; Title 13; Title 48; Title 49; Title 67 and Title 68.

SB 539 establishes new rules for taxing multi-unit rental properties (four or more units) that receive federal, state, or local incentives tied to low-income housing restrictions, such as tax credits or rent subsidies. Property owners must notify local assessors by December 31 each year if their property has such restrictions, and assessors must value these properties using specific methods - including adjusting for rent differences between restricted and non-restricted units and excluding tax credits from valuation. The bill requires a higher capitalization rate (50-150 basis points above the national average) for these properties to reflect their reduced market value, with rules taking effect for tax year 2026. This directly affects owners of qualifying rental housing and property assessors statewide.
