HB 4304 amends Oklahoma's tax exemption rules to clarify and expand which purchases by local governments and public agencies qualify for sales tax exemption. It specifically adds an exemption for sales related to "qualified federal facilities" under the Oklahoma Federal Facilities Development Act, where property ownership transfers immediately to a political subdivision. The bill also clarifies that government entities can designate agents to make tax-exempt purchases on their behalf, requires written certification for such purchases, and updates the list of eligible public authorities (including universities and special districts) that qualify for exemptions. This directly affects local governments, public agencies, and their contractors by reducing tax burdens on eligible purchases.

The bill text was updated to reflect its final floor version, replacing the draft 'House Committee Substitute' header with the official 'Floor Version' designation.

No substantive policy, legal, or financial changes were made to the actual content of the bill.
Scope change
The scope of the bill's exemptions remains unchanged; the only modification is the document versioning to reflect its progression through the legislative process.
