In short
Florida does not have a state level property tax exemption for AI data centers. But it offers a valuable sales tax exemption that covers equipment, construction materials, software, and electricity. A 2025 law (HB 7031) raised the critical IT load a facility must have to keep the exemption from 15 megawatts to 100 megawatts. AI data centers below 100 MW will lose the exemption at their next five year review with no grandfather protection. Local governments can grant property tax abatements through economic development agreements to offset local property tax. A 2026 law (SB 484) adds utility cost rules that raise electricity rates for large AI data centers and gives local governments more power over zoning and water permits. So the state level tax break now only lasts for mega scale projects, and local property tax breaks require negotiation.
What is Florida’s sales tax exemption for AI data centers?
The exemption covers equipment, materials, and electricity
Florida exempts the purchase and use of data center property from the state’s 6 percent sales tax and any local discretionary sales surtax. These surtaxes usually range from 0.5 percent to 1.5 percent. Fla. Stat. § 212.055, Fla. Dept. of Revenue, Discretionary Sales Surtax
The law calls the exempt items data center property. It defines that term broadly to include almost everything you need to build, outfit, and run an AI data center. Data center property covers servers, racks, cooling systems, power equipment, software, and even the electricity consumed at the site. Fla. Stat. § 212.08(5)(r)1.d.-Data-center-property.pdf)
You must meet a power threshold, an investment minimum, and other tests
To get the exemption, your project must be a statutory data center, which is what we call an AI data center. The statute defines a data center as a facility on one contiguous parcel, built after July 1, 2017, that houses and operates computer servers. It must have a critical IT load of at least 15 megawatts overall and at least 1 megawatt per individual owner or tenant. Fla. Stat. § 212.08(5)(r)1.c.-Data-center-property.pdf) That is the entry threshold. But a 2025 change, explained below, means you must reach 100 megawatts of critical IT load to keep the exemption past the first five year review.
Critical IT load is the portion of electric power capacity, expressed in megawatts, reserved solely for owners or tenants of a data center to operate their computer server equipment. It does not include ancillary load for cooling, lighting, common areas, or other equipment. Fla. Stat. § 212.08(5)(r)1.a.-Data-center-property.pdf)
You also need a cumulative capital investment of at least $150 million. This counts all expenses owners and tenants incur after July 1, 2017 for the AI data center. The investment does not include buying improved real property that was operating as a data center at the time of acquisition or within six months before the acquisition. Fla. Stat. § 212.08(5)(r)1.b.
You must meet all these requirements within five years after you start construction. Fla. Stat. § 212.08(5)(r)2.-Data-center-property.pdf)
How the application process works
The process has two main steps.
First, you file Form DR-1214DCP with the Florida Department of Revenue to get a temporary tax exemption certificate. The application states that you are seeking a qualifying data center and that you seek to meet the exemption requirements. Fla. Admin. Code R. 12A-1.108, Form DR-1214DCP With the temporary certificate, you can buy data center property without paying sales tax.
Second, once you have met all the requirements, you deliver the temporary certificate to the Department with two sworn declarations. One comes from a licensed professional engineer who certifies the critical IT load. The other comes from a Florida CPA who certifies the cumulative capital investment. Neither professional can be professionally related to the owners, tenants, or contractors, except that they may be retained by a data center owner to certify that the requirements have been met. Fla. Stat. § 212.08(5)(r)3.b.(I)-Data-center-property.pdf) If the Department approves, it issues a permanent tax exemption certificate on Form DR-14DCP. Fla. Stat. § 212.08(5)(r)3.b.(II), Form DR-14DCP
The permanent certificate lasts as long as the AI data center operates. But the Department reviews it every five years to confirm you still meet the requirements. Fla. Stat. § 212.08(5)(r)3.b.(III)
If an audit later finds you did not meet the criteria, the tax you avoided becomes due immediately with interest and penalties. The Department can look back up to six years from the purchase date. Fla. Stat. § 212.08(5)(r)3.c.-Data-center-property.pdf)
The Department may not issue a new temporary certificate after June 30, 2037. Fla. Stat. § 212.08(5)(r)4. So there is a deadline to start a project and claim the exemption.
What changed in 2025 with HB 7031?
The critical IT load requirement jumped to 100 megawatts
In 2025, the Florida legislature passed a large tax bill, HB 7031 (Chapter 2025-208). HB 7031 (2025) One provision changed the data center exemption in a major way. It raised the critical IT load a facility must have to keep the exemption from 15 megawatts to 100 megawatts. The change took effect August 1, 2025. HB 7031 Final Bill Analysis
The higher threshold works through the existing five year review. At each review, the certificateholder must certify to the Department that the AI data center still meets the critical IT load requirement. Now that requirement is 100 MW instead of 15 MW. A facility below 100 MW will fail the review and lose its exemption.
HB 7031 did not include a grandfather clause. Existing AI data centers below 100 MW get no protection. They lose the exemption at their next five year review, just like a new applicant. So a 30 MW AI data center that once bought equipment tax free will eventually owe sales tax on future purchases and electricity.
The law also repealed the commercial lease sales tax
HB 7031 did another thing that helps AI data center tenants. It repealed Florida’s sales tax on commercial leases, effective October 1, 2025. Before the repeal, landlords charged a 2 percent state tax plus local surtax on rent. Now that tax is gone. The change saves businesses an estimated $900 million each year. HB 7031 (2025), CoStar, CoStar analysis
For a tenant, the lease tax repeal cuts occupancy costs. But for a smaller AI data center, the loss of the equipment and electricity exemption may outweigh that saving.
A quick look at the before and after
| What changed | Before August 1, 2025 | After August 1, 2025 |
|---|---|---|
| Critical IT load to maintain exemption | 15 megawatts | 100 megawatts |
| Projects that keep the exemption | All qualifying AI data centers | Only those with 100 MW or more of critical IT load |
| Grandfather protection for existing facilities | Permanent exemption subject to reviews | No grandfather, exemption ends at next five year review |
| State sales tax on commercial rent | 2 percent plus local surtax | Repealed October 1, 2025 |
What the 100 megawatt threshold means for developers?
An AI data center project below 100 MW now faces a very different tax picture.
First, future purchases of data center property will be taxable. That includes construction materials, servers, cooling gear, and software. Under Florida law, contractors are generally the ultimate consumers of the materials they buy, so they pay sales tax unless an exemption applies. Fla. Admin. Code R. 12A-1.051 Contractors who priced bids assuming tax free supplies will see costs rise.
Second, electricity becomes taxable. Electricity counts as data center property and was exempt. A sub 100 MW facility now owes sales tax on its power bill, a large and recurring cost.
Third, a data center that claimed the exemption and later fails the review faces a clawback. The Department can assess back taxes, interest, and penalties on the earlier tax free purchases.
Mega scale projects above 100 MW can still benefit. The Atlas Compute campus in Fort Pierce plans 240 MW of initial capacity with planned expansion of up to 1 gigawatt. Yahoo Finance That sits well above the threshold. Another large project, the Fort Meade campus in Polk County, aims for up to 1.2 GW. But most of Florida’s existing AI data centers are far smaller. The largest operating facility by capacity, Centersquare TPA1 in Tampa, is only 12 MW. Cleanview The 100 MW bar shuts out the majority of the current market from the state level tax break.
Local property tax abatements fill part of the gap
Florida has no state level property tax exemption for AI data centers. The state simply does not offer one. But there is a local tool that can help.
Under Article VII, Section 3 of the Florida Constitution and section 196.1995, Florida Statutes, counties and municipalities can grant Economic Development Ad Valorem Tax Exemptions to qualifying businesses after voter referendum approval. EDR report, Section 196.1995, Fla. Stat. This is a property tax abatement. The local government votes to exempt a portion of the value of new improvements from property taxes for a set period, often up to ten years. The tax savings equal the exempted value multiplied by the local millage rate.
These abatements are not automatic. A developer must negotiate with the local government and usually promise job creation and capital investment. Upon a majority vote in favor of such authority in a referendum, the governing board may, at its discretion, grant the exemption by ordinance. Fla. Stat. § 196.1995
A recent real example is the Fort Meade AI data center campus in Polk County. The city approved a twenty year development agreement that includes a $150 million, ten year local tax break. Florida Data Centers This is a property tax abatement. Other projects may seek similar deals.
Because there is no state level property tax exemption, an AI data center’s real and personal property is normally fully taxable at local millage rates. The local economic development exemption is the only way to reduce that local property tax burden.
How SB 484 in 2026 shapes the tax and cost picture
SB 484, signed into law in May 2026 and effective July 1, 2026, is not a tax bill. It creates a new regulatory framework for large scale AI data centers. The law requires large scale AI data centers to bear their own full cost of service and prevents those costs from being shifted to ratepayers. SB 484 (2026)
The law defines a large load customer as one with an anticipated monthly peak load of 50 megawatts or more, calculated as the highest average load over any 15 minute interval. It prohibits splitting loads to avoid the threshold. SB 484 Bill Analysis
SB 484 requires the Florida Public Service Commission to develop large load tariff rules. These rules must ensure that large load customers pay the full cost of serving them, with no cost shifting to residential or small business ratepayers. The law also bars utilities from serving AI data centers owned or controlled by foreign countries of concern. Governor press release
In practice, this means higher electricity rates. Florida Power and Light already obtained approval for new Large Load Contract Service tariffs in early 2026. Under those tariffs, the typical rate for an eligible large load customer is about 10.2 cents per kilowatt hour, compared to about 6 cents per kilowatt hour under the prior tariff. That is a roughly 70 percent increase. FEIA brief To qualify, a customer must have at least 50 MW of peak load, an 85 percent minimum load factor, and a take or pay demand charge of at least 70 percent. So the customer must commit to paying for a large block of power even if it uses less.
SB 484 also gives local governments clear authority over zoning, permitting, and land use for these large load projects. An AI data center cannot be labeled an electric substation to bypass zoning rules. The law creates new consumptive use permit requirements and allows water management districts to require reclaimed water. It bars consumptive use permits for large scale data centers if the proposed water use would be harmful to water resources of the area. SB 484 Bill Analysis These rules can delay a project or block it entirely.
For a developer, the combination of higher power bills, stricter water rules, and local opposition can eat into the savings from the sales tax exemption and any local property tax abatement. The net tax benefit shrinks.
Key takeaways
- The Florida sales tax exemption for AI data center property is powerful but now only benefits projects that can reach 100 MW of critical IT load and maintain it through each five year review.
- Existing AI data centers below 100 MW get no grandfather protection. They will lose the exemption at their next review and should budget for sales tax on future purchases and electricity.
- Developers of smaller projects must plan for sales tax on equipment, materials, and power. Contractors should price bids accordingly.
- There is no state level property tax exemption. Seek a local Economic Development Ad Valorem Tax Exemption by negotiating with the county or municipality. These require public approval and are not guaranteed.
- SB 484 will raise electricity rates for large load customers and impose new water and zoning hurdles. Model the all in cost of power under the new FPL LLCS tariffs before relying on the sales tax exemption.
- Watch whether the 2026 Legislature revisits the 100 MW threshold or adds a grandfather provision now that SB 484 provides a broader regulatory framework.
Frequently asked questions
Q:What is Florida’s sales tax exemption for AI data centers?
A:It exempts the purchase and use of data center property, like servers, cooling gear, software, and electricity, from Florida’s 6 percent state sales tax and local surtax. The exemption requires a qualifying AI data center to meet certain power and investment thresholds.
Q:What is critical IT load and why does it matter?
A:Critical IT load is the amount of power in megawatts reserved only for running the computer servers. It does not include cooling, lighting, or other building loads. The exemption originally required 15 MW. Now, to keep the exemption past the five year review, a facility must have 100 MW of critical IT load.
Q:What projects qualify for the exemption today?
A:An AI data center built after July 1, 2017 on contiguous parcels, with at least 15 MW of critical IT load (1 MW per owner or tenant), and $150 million in cumulative capital investment. To keep the exemption beyond the five year mark, it must reach 100 MW of critical IT load.
Q:Does the 2025 change affect existing AI data centers?
A:Yes. There is no grandfather clause. When an existing facility below 100 MW reaches its next five year review, it must certify a 100 MW critical IT load. If it cannot, the Department revokes the permanent exemption and future purchases become taxable.
Q:Is there a Florida property tax exemption for AI data centers?
A:No state level property tax exemption exists. However, counties and municipalities can offer property tax abatements through the Economic Development Ad Valorem Tax Exemption program. These are negotiated locally and require public approval.
Q:How does the commercial lease tax repeal help AI data center tenants?
A:Since October 1, 2025, Florida no longer imposes sales tax on commercial rent. That saves tenants roughly 2 percent state tax plus local surtax on their lease payments. For an AI data center tenant, this lowers occupancy costs, though it may not offset the loss of the equipment and electricity tax exemption.
Q:What is SB 484 and how does it affect my project?
A:SB 484 is a 2026 Florida law that regulates large load AI data centers with a peak load of 50 MW or more. It forces these customers to pay the full cost of utility service, resulting in higher electricity rates. It also tightens water permitting and gives local governments more control over zoning. These rules raise costs and can delay or block projects.
Q:How do I apply for the sales tax exemption?
A:File Form DR-1214DCP with the Department of Revenue to get a temporary certificate. After you meet the investment and power requirements, submit sworn declarations from an independent engineer and CPA to convert to a permanent certificate (Form DR-14DCP). You must do all of this within five years of starting construction.
Q:Is there a deadline to start a project and get the exemption?
A:The Department cannot issue a new temporary certificate after June 30, 2037. You must begin the process before that date.
Q:Can a contractor benefit from the exemption?
A:Yes. Contractors can buy materials for a qualifying AI data center without paying sales tax if they present a copy of the owner’s exemption certificate and a signed Certificate of Entitlement to each vendor. This only works if the data center itself qualifies.
