Alabama Data Center Tax Incentives: Tiers, Exemptions, and Abatements

Alabama’s data center tax incentives combine two stackable programs: Chapter 9B of the Alabama Code (the Tax Incentive Reform Act of 1992) provides sales and use tax exemptions and non-educational property tax abatements for 10, 20, or 30 years depending on investment size, and the Alabama Jobs Act layers on an investment credit worth up to 1.5% of qualified capital per year and a payroll rebate of up to 3%. To qualify, a facility must create at least 20 new jobs with average annual compensation of at least $40,000 including benefits.¹

How the Three Investment Tiers Work

The length of both the sales tax exemption and the property tax abatement scales with cumulative capital investment by the private user or users of the facility. There are three tiers:

Tier 1: up to $200 million invested within 10 years earns 10 years of sales and use tax exemptions plus 10 years of property tax abatement.
Tier 2: more than $200 million but not more than $400 million within 10 years earns 20 years of each.
Tier 3: more than $200 million within 10 years and exceeding $400 million within 20 years earns 30 years of each.

A project that starts in Tier 1 can move up if cumulative spending crosses the next threshold inside the statutory window, which is why phased hyperscale campuses gravitate to this structure.²

The property tax abatement clock starts when the property becomes “owned for federal income tax purposes” by the operator, not on the date the abatement agreement is signed. In build-to-suit and sale-leaseback arrangements, that distinction can shift the effective start date by months or years.¹

Who Qualifies as a Data Processing Center

Section 40-9B-3 sets two baseline requirements. The facility must create at least 20 new jobs, and the average annual total compensation for those positions, including benefits, must be at least $40,000. Because benefits count toward the average, base salary alone can be lower.¹

The 20-job floor is deliberately low relative to the capital involved. A $400 million project employing 20 people works out to $20 million of investment per job, which reflects that modern data centers are capital-intensive rather than labor-intensive.

Qualifying activities are broad: data processing, hosting, automated data entry, application service provisioning, general time-share mainframe operations, and the processing, storage, backup, retrieval, or distribution of data. Co-location centers where a lessor and one or more lessees share the facility also qualify, and the aggregate investment of all users counts toward the tier thresholds.¹

What the Sales and Use Tax Exemption Covers

Alabama’s general state sales tax rate is 4%.³ For a qualifying data center, the Chapter 9B exemption removes that tax on purchases of tangible personal property and taxable services whose costs can be capitalized for federal income tax purposes. That reaches servers, storage arrays, networking gear, cooling systems, power distribution equipment, generators, and the construction materials that go into the building itself. Electricity used to run the facility can also qualify.

The exemption runs for the same 10, 20, or 30 years tied to the investment tier.²

One important limit: the state-level exemption does not automatically extend to local sales taxes. Counties and cities must pass their own resolutions to abate their portion. Combined state and local sales tax rates in Alabama average over 9%, so the local piece is often larger than the state piece. Negotiate the local exemption as part of the initial incentive package; retrofitting it after construction begins is difficult.

How Property Tax Abatements Work

Chapter 9B abatements apply only to the non-educational portion of ad valorem taxes. The educational share stays intact to protect school funding regardless of any abatement agreement. Within that scope, the abatement covers both real property (land, buildings, site improvements) and personal property (servers, networking equipment, cooling infrastructure, generators).²

Approval mechanics change at the 10-year mark. For years 1 through 10, a single granting authority (the county, city, or a public industrial authority) can abate state, county, and city non-educational property taxes through one resolution. For years 11 through 20, each taxing jurisdiction must independently grant its share: the county commission for county taxes, the city council for municipal taxes, and the governor for state non-educational property taxes. That second layer of approval is where extension deals can stall, so operators pursuing a 20- or 30-year package should build political relationships early at every level.²

Alabama Jobs Act Credits That Stack on Top

Chapter 9B is not the whole package. The Alabama Jobs Act adds two more incentives that qualifying data centers can layer on:

An investment credit of up to 1.5% per year of qualified capital investment, available for up to 10 years, or up to 15 years for projects in a Targeted or Jumpstart County. The credit offsets Alabama income tax, financial institution excise tax, insurance premium tax, utility tax, or utility license tax liability, and unused credits carry forward for five years.
A jobs credit of up to 3% per year of the previous year’s gross payroll (excluding fringe benefits) for eligible Alabama-resident employees, available for up to 10 years, paid as a cash rebate.

⁴

On a $400 million project, a 1.5% annual investment credit is $6 million a year, or as much as $60 million across the full 10-year term. At the governor’s discretion, the first five years of the investment credit can be transferred to another taxpayer for at least 85% of face value, which gives operators without enough Alabama tax liability a way to monetize the credit rather than let it sit.⁴

Data centers also enter the Jobs Act under a reduced job-creation threshold: net new full-time positions are enough, rather than the higher hiring floors that apply to most other industries.

How to Apply

Chapter 9B applications go through local government first, then the Alabama Department of Revenue (ALDOR). The general sequence:

Lock in the project site. No abatement can be granted before the location is set, and the site determines which local government has jurisdiction.
File Form CO:CAA, the “Application to Granting Authority for Abatement of Taxes,” with the county, city, or public industrial authority that covers the site.
Obtain a local resolution approving the abatement and execute a written abatement agreement with the granting authority.
Within 90 days of the local grant, submit the full package to ALDOR: the executed abatement agreement, the certified resolution, the original Form CO:CAA with a list of property to be acquired, a certificate of exemption application (Form ST:EX-A2), proof of enrollment in E-Verify, a copy of the resolution sent to the county commission if a city or municipal authority granted the abatement, and proof of project notification filed with the Alabama Department of Commerce.
Receive the Certificate of Exemption from ALDOR, which the operator and its contractors present to vendors for tax-free purchases on the project.

Contractors and subcontractors buying materials for the project must file their own Form ST:EX-A2 with ALDOR, together with a letter from the operator or general contractor confirming that the purchases are being made on behalf of the project. Skipping this step is a routine mistake: contractors end up paying sales tax at the register and then chasing refunds.²

One boundary worth noting: projects located on premises where the Alabama State Port Authority has an ownership or possessory interest need separate written approval from the Governor, the Finance Director, and the Director of the Alabama State Port Authority before any local body can grant a Chapter 9B abatement.⁵ Data centers on privately held or commercially leased land are not affected by that carve-out.

Staying Compliant and Clawback Risk

Winning the abatement is the easy part. Keeping it requires meeting the investment and employment commitments in the abatement agreement, and Alabama tracks those metrics through annual reporting.

The most common slip is letting the headcount fall below the 20-job minimum. Data centers automate hard, and staffing can drift down after initial buildout as remote monitoring replaces on-site personnel. Define qualifying positions broadly in the original agreement and track headcount quarterly, not just at year-end.

If a facility shuts down or relocates before the abatement period ends, the state can pursue repayment of previously waived taxes. How painful that gets depends on how the abatement agreement is drafted. Some agreements prorate the penalty to the shortfall. Others treat early termination as grounds for full recapture. Getting the clawback language right during negotiation is far cheaper than litigating it later.

Pending 2026 Legislation to Watch

The incentive program is under active legislative review. In early 2026, the Alabama Senate and a House committee advanced legislation that would cap the maximum abatement at 20 years instead of 30 and strip state construction tax abatements for projects consuming more than 100 megawatts once those facilities enter service. That bill has not been signed into law as of this writing. A project that qualifies for the 30-year tier under current law could be capped at 20 if the rules change before the abatement agreement is executed, so operators on multi-year timelines should track the session closely and, where possible, get their abatement agreement executed under the current statute.
