Arizona Data Center Tax Exemption: No Jobs Requirement, and Twenty Years for Reusing a Vacant Building

Arizona's computer data center programme explained: the $25M and $50M county tiers, why leased equipment counts toward the threshold, how colocation tenants qualify in their own right at 500 kW, the twenty-year period for reusing a half-vacant building, and the one recapture the state cannot claw back.

Arizona's programme is the one that most rewards reading the statute, because three of its provisions are the opposite of what the neighbouring states do, and each of the three changes what a project can be.

Start with the one that is simply absent: Arizona attaches no employment condition of any kind. No job count, no payroll floor, no wage test. Georgia asks for "new quality jobs", Virginia for 50 jobs at 1.5× the local prevailing wage, Texas for 20 jobs at 120% of the county average weekly wage, Ohio for $1.5 million of payroll. Arizona asks for investment and nothing else.

The rule

Source: A.R.S. § 41-1519 (Arizona Legislature). The relief itself is delivered as deductions under A.R.S. §§ 42-5061 (retail classification), 42-5075 (prime contracting), 42-5159 (use tax) and 42-6004 (exemption from municipal tax), covering gross proceeds or income from the sale, use, installation, assembly, repair or maintenance of computer data center equipment.

Two things follow from that list of sections. The relief reaches municipal tax, not only the state's — unlike Texas, where the exemption "applies only to the 6.25 percent state sales tax" and the retailer must still collect local tax (worked through here). And because prime contracting is included, it reaches the labour of installing and maintaining the equipment, not just the equipment itself.

The county split works like Georgia's county tiers with the dial turned down to two positions: the same project needs twice the investment to qualify on one side of a county line as on the other. Which side a given county falls on is a population question to put to the certifying authority, not something to assume.

Leased equipment counts — the reverse of Texas

The threshold is met by "new investment, including costs of land, buildings, improvements, modular data centers and computer data center equipment, whether owned or leased or paid for pursuant to a right to use agreement".

Compare Texas, which excludes from its capital investment calculation "property that is leased under an operating lease". A sponsor that leases its servers, generators and cooling plant builds no threshold in Texas and builds the full threshold in Arizona. If a pipeline deck says "we lease the equipment to improve early-year cash flow", that choice is free in one state and disqualifying in the other.

And the test is collective: a data center must meet the requirement "after taking into account the combined investments made by the owner, operator or qualified colocation tenants". A single building can also be assembled from parts — an owner "may aggregate one or more of the parcels, buildings, condominiums or modular data centers in a facility into a single computer data center" if together they clear the threshold.

Colocation is written into the statute, and tenants are protected

This is the sharpest contrast on the site. Texas allows a qualifying data center only one occupant and forbids subleasing. Arizona defines the tenant:

"Qualified colocation tenant" means an entity that contracts with the owner, the operator or another qualified colocation tenant of a computer data center that is certified pursuant to this section to use or occupy all or part of the computer data center for at least five hundred kilowatts per month for a period of two or more years.

So a multi-tenant hall is the expected case, each tenant with a 500 kW floor and a two-year minimum, and each with its own qualification period running from the date it signs.

Then the provision that matters most to a tenant, and that almost nobody will volunteer: "A qualified colocation tenant is not subject to recapture of any part of tax relief received pursuant to this section" — except that a "contributing qualified colocation tenant" may be. A tenant's benefit, in other words, largely survives the operator's failure to hit its own investment number.

Twenty years, for reusing a building nobody wanted

The "sustainable redevelopment project" definition doubles the period from ten years to twenty. It is satisfied by either of two things:

1. a newly constructed data center with at least $200,000,000 of investment that attains Energy Star, Green Globes, or LEED certification (or an equivalent) "and was not previously certified under these standards"; or
2. a data center that occupies an existing facility which either

• "[w]as at least fifty percent vacant for six of the twelve consecutive months before the acquisition by purchase or lease", or
• attains one of those same green certifications, not previously held.

The second route is the interesting one. A project that takes over a half-empty building gets twenty years of relief rather than ten, with no additional investment requirement beyond the ordinary $25M or $50M — and all demolition and expansion work on such a site counts toward the project.

That is a real and unusual arbitrage: in a market with vacant industrial or office stock, adaptive reuse is worth ten extra years of tax relief. It also cuts against the usual assumption that a greenfield build is the cleaner structure. If an Arizona offering is a new build under $200 million, it is in the ten-year bucket — and the twenty-year bucket was available for the price of a different site.

Two recaptures, and the one Arizona cannot claw back

The statute distinguishes failing your investment promise from breaking its rules, and treats them very differently.

Fail the investment test (subsection E, paragraph 1): the authority "shall revoke the computer data center's certification", every qualification period "automatically terminates", and the Department of Revenue "may recapture all or part of the tax relief provided directly to the owners and operators". Retroactive.

Violate subsection M: certification is revoked and the qualification periods terminate, but the Department of Revenue "may not recapture any tax relief provided directly to the owner, operator or qualified colocation tenant before the date of revocation". Prospective only.

What subsection M forbids is worth knowing on its own, because it touches the most-discussed structure in the sector. The section "does not allow a computer data center to do either of the following":

1. "Generate electricity for resale purposes."
2. "Generate, provide or sell electricity outside of the computer data center."

A certified Arizona data center may generate power for itself. It may not sell any of it beyond the fence. A project that builds generation and later sells surplus loses the certification going forward and keeps everything it has already saved — which is a strange incentive, and a useful thing to know before reading a plan that treats surplus power as a second revenue line. The underlying question is on behind-the-meter power.

Revocations may be appealed.

The six states side by side

This is the whole point of doing them one at a time.

Cells marked "—" are not that state's silence; they are questions we have not examined on that state's page.

Not one of those investment floors is reachable by a typical retail private placement. That is the single most useful thing on this page for most readers: across six states and every tier within them, the state sales tax exemption is not a benefit a small private data center deal can claim. If a $5–30 million offering implies one, ask which threshold it expects to clear.

Six checks on an Arizona project

1. Is the data center certified, and what is the effective date? The qualification period is counted in full calendar years from it.
2. Which investment tier applies, $25M or $50M, and is the county above or below 800,000 people?
3. Is the project claiming ten years or twenty? If twenty, on which limb — a $200M green-certified new build, or an existing facility that was at least 50% vacant for six of the twelve months before acquisition?
4. Is it a colocation deal? If so, does each tenant take at least 500 kW for two or more years, and when does each tenant's own qualification period start?
5. Who bears a recapture if the investment test is missed — and does the sponsor know that tenants are largely exempt from recapture while owners and operators are not?
6. Does any part of the plan involve selling power off-site? That forfeits the certification going forward.

Next: Texas, the mirror image on leasing and colocation; Ohio, where the percentage and term are negotiated rather than published; Virginia, the largest programme; Georgia, the lowest floor; and data center tax incentives for the shape they share.
