HB 4305 modifies how county assessors value affordable housing properties in Oklahoma. It requires assessors to base fair cash value on projected income during construction/lease-up and adjust yearly using net income changes for stabilized properties. If such a property is sold without its affordable housing restrictions, an additional tax is imposed equal to the difference between taxes paid under this method and what would have been paid at the sale price. This tax must be paid by the property owner within 20 days of receiving written notice from the county assessor after the sale.

MODERATE
The bill was converted from the House version to the Senate floor version, which includes substantive amendments to the definitions of property types and valuation methods. The Senate version adds specific criteria for organizations to qualify for tax exemptions, clarifies the valuation process for properties under construction or in a lease-up phase, and mandates that organizations submit annual audits to the county assessor by May 1.
Scope change
The bill's scope was narrowed and clarified to apply only to real property owned by specific types of organizations that meet strict federal and state funding and usage requirements, such as those financed with low-income housing tax credits.
ELIGIBILITY
Added specific criteria requiring organizations to own property financed with federal low-income housing tax credits and subject to land use or regulatory agreements.
DEFINITION
Added precise definitions for 'Active construction' and 'Lease-up' to clarify which properties are subject to special valuation rules.
Modified the definition of 'Organization' to explicitly exclude properties that receive exempt treatment under other sections of the tax code.
REQUIREMENT
Added a requirement for qualifying organizations to deliver an annual financial audit to the county assessor by May 1.
Added a requirement for the county assessor to establish a formal process for determining market-derived capitalization rates based on project and investor data.
