Summary
House Bill 646 would create a Data Center Study Commission and change several Ohio Revised Code sections about data centers, including the data center sales tax exemption statute, section 122.175. The House passed an amended version on 18 March 2026. On 10 June 2026 the Senate Energy Committee reported a substitute bill, which was then informally passed and sent back to the committee. The status page opened on 23 September 2026 shows no later action. It is a pending proposal, not law.
What this does not establish
- The bill text was not read for this record; the scope comes from the bill's official short and long titles. The House-passed text and the Senate substitute were not compared.
- The long title lists the sections the bill would amend or enact; it does not show what each new section would require.
- Section 122.175 is the separate record oh-orc-122175-data-center-exemption.
Unresolved questions
- Contents of the Senate Energy Committee substitute bill.
- Whether the Senate will act on the bill before the 136th General Assembly ends.
Relationships
Supersession means a later instrument replaces the earlier legal effect. Repeal links identify the repeal instrument and the measure it ends. A later implementation or related letter is not treated as a replacement unless the record says so.
