Illinois Paused Data-Center Tax Breaks. The Deals Didn't Stop.

Key Highlights

• Gov. Pritzker directed DCEO to pause all new data-center tax-incentive agreements starting July 1, 2026; existing incentives are unaffected.
• From 2020-24, 27 Illinois data centers received more than $983M in state tax incentives, per state reports.
• Chicago Mayor Brandon Johnson this week formally proposed a one-year moratorium on data-center development (The Real Deal, Sept 26).
• Joliet approved Hillwood's 795-acre, ~$20B data-center campus in March, 8-1, despite resident opposition.
• Regulators separately approved ComEd deposit requirements that raise costs for large-load projects above 200 MW.

The Signal

• State and local policy are tightening at the same time capital keeps landing -- the incentive freeze has not stopped individual megaproject approvals.
• A proposed moratorium in the region's largest city moves the risk from 'incentives may shrink' to 'entitlement may not be available at all' within city limits.

Implications

Illinois is no longer a market where incentive terms or approval paths can be assumed to hold through a project's entitlement timeline. Underwrite for narrower state support, higher utility deposits and jurisdiction-by-jurisdiction approval risk -- suburban sites with existing approvals gain relative value if Chicago's moratorium advances.

Illinois didn't stop building data centers -- it stopped promising to keep paying for them, and Chicago may stop approving them.

Background facts (incentive pause, Joliet approval) predate the 48-hour window; the news hook is The Real Deal's Sept 26 report.
