Changes to Tax Breaks for Data Centers in Alabama

Last scannedAug 24, 2026, 9:06 AM

In one sentence

This law limits how long data centers can receive tax breaks, requires them to pay certain taxes on construction items after they start operating, and extends the deadline for these incentives.

What it does

  • Limits the maximum time a data center can get a tax break to 20 years starting in 2027.
  • Allows an extra 10-year extension if the company agrees in writing to keep investing locally and state agencies approve it.
  • Stops tax breaks on non-education property taxes once the data center begins operating, but allows education-related taxes to continue being abated.
  • Requires companies to pay sales taxes on building materials and power equipment after the facility opens.
  • Sends money collected from these construction taxes into the State General Fund instead of other accounts.
  • Extends the expiration date for this tax incentive program from July 31, 2028 to July 31, 2032.

Who it affects

  • Companies building or expanding data processing centers in Alabama
  • Local governments that grant tax abatements under the Tax Incentive Reform Act
  • The Department of Revenue and the Department of Commerce

Limits and unknowns

  • The law only applies to tax breaks granted on or after January 1, 2027.
  • It is unclear how many companies will qualify for the extra 10-year extension since it requires written agreements and state approval.
