Summary
Iowa's 2025 Acts chapter 148 (House File 976) amended the state's data center sales tax exemptions. For data center construction or additions on or after the division's 6 June 2025 effective date, the exemptions for backup generation fuel and electricity last only for the first 10 or 15 years of operation, depending on city size, while data centers already operating keep an unlimited duration. The act does not repeal the exemption and does not stop any data center from operating.
What this does not establish
- The act was approved on 6 June 2025, and section 87 makes the division effective on enactment, so the approval day is stored as the effective day.
- This record is the amending act. The exemption it amends is recorded separately as Iowa Code section 423.3(95).
- Other divisions of chapter 148 are outside this record.
Unresolved questions
None recorded.
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.
