In short
Florida exempts property used at a qualifying AI data center from the state sales tax (6%) and most local option surtaxes (typically 1% to 1.5%). The exemption covers construction materials, servers, cooling equipment, and electricity. Fla. Stat. § 212.08(5)(r)1.d.
As of August 1, 2025, the critical IT load threshold rose from 15 megawatts to 100 megawatts. Ch. 2025-208, Laws of Fla. § 46 Critical IT load means the power reserved for the servers themselves, not the cooling or lighting. A facility must now have a total critical IT load of 100 MW or more, and each owner or tenant must have a dedicated load of at least 1 MW. The minimum cumulative capital investment (total spending on the facility) remains $150 million. All requirements must be met within five years of starting construction. Fla. Admin. Code R. 12A-1.108
There is no grandfather clause. Existing AI data centers below 100 MW will lose the exemption at their next five year review by the Department of Revenue. Law firm analysis
The exemption is administered through a temporary certificate application (Form DR-1214DCP) and a permanent certificate once requirements are met. The DOR may not issue temporary certificates after June 30, 2037. Fla. Stat. § 212.08(5)(r)4., Ch. 2025-208, Laws of Florida Separately, the commercial rent tax was repealed effective October 1, 2025, removing Florida’s business rent tax on commercial real property leases. Ch. 2025-208, § 37 A 2026 law requires utilities to charge large AI data centers (50 MW peak load and above) their own cost of service tariffs, with no cost shifting to the general body of ratepayers. Ch. 2026-65
What is the Florida sales tax exemption for AI data centers?
Florida enacted the AI data center sales tax exemption in 2017 to attract large computing facilities. It exempts qualifying purchases from the state sales tax (6%) and applicable local surtaxes (usually 1% to 1.5%). For a large project, that can mean millions of dollars saved on equipment and electricity.
The exemption covers what the statute calls data center property. That term is broad. It includes construction materials, component parts, machinery, servers, backup power systems, cooling equipment, dehumidifiers, security hardware, and operating software (including updates and upgrades). It also covers electricity used exclusively at the AI data center. The property must be used exclusively at a facility that meets the statutory definition of a data center. Fla. Stat. § 212.08(5)(r)1.c. and 1.d.
The statute defines a data center as a facility that consists of one or more contiguous parcels in this state, along with the buildings, substations and other infrastructure, fixtures, and personal property located on the parcels, is used exclusively to house and operate equipment that receives, stores, aggregates, manages, processes, transforms, retrieves, researches, or transmits data or equipment necessary for the proper operation of such data equipment, has a critical IT load of 100 megawatts or higher and a critical IT load of 1 megawatt or higher dedicated to each individual owner or tenant, and is constructed on or after July 1, 2017. Fla. Stat. § 212.08(5)(r)1.c. Older facilities do not qualify unless they were constructed after that date.
The exemption is not automatic. The owner or operator must apply to the Department of Revenue for a temporary certificate, then meet all the investment and power thresholds to get a permanent certificate. Those requirements changed sharply in 2025.
What changed in 2025?
The Florida Legislature passed an omnibus tax bill, HB 7031, in June 2025. The Governor signed it on June 30, 2025, as Chapter 2025-208. The bill made two big changes for AI data centers. It raised the critical IT load threshold from 15 MW to 100 MW. And it repealed the commercial rent tax. 2025 HB 7031
The threshold increase took effect August 1, 2025. Before that date, an AI data center needed only 15 MW of critical IT load to qualify. After that date, it needs 100 MW. Tax alert The bill also extended the deadline for DOR to issue temporary certificates from June 30, 2027 to June 30, 2037. A separate 2025 bill, HB 7031, extended the data center exemption certificate deadline to June 30, 2037, and raised the qualifying power threshold from 15 MW to 100 MW. HB 7031 bill summary
The commercial rent tax repeal took effect October 1, 2025. That tax (Fla. Stat. § 212.031) had applied to commercial lease payments, including AI data center leases, at rates typically 3% to 3.5% depending on the county. Its repeal was part of the same tax package and may have been a trade off for raising the data center exemption threshold. HB 7031 bill summary, Law firm analysis
The 2025 changes did not alter the $150 million cumulative capital investment requirement or the 1 MW minimum per owner or tenant. Those stayed the same.
What are the current eligibility requirements?
To qualify for the exemption, an AI data center must now meet these requirements, all within five years of beginning construction.
| Requirement | Current Threshold | Threshold before Aug 1, 2025 |
|---|---|---|
| Total critical IT load | 100 MW or higher | 15 MW or higher |
| Cumulative capital investment | $150 million or more | $150 million or more |
| IT load per owner or tenant | 1 MW or higher | 1 MW or higher |
| Deadline to obtain temporary certificate | Apply before June 30, 2037 | June 30, 2027 |
Fla. Stat. § 212.08(5)(r)2. and 4., HB 7031
Critical IT load means the power reserved solely for running the servers themselves. It does not include power for cooling, lighting, or common areas. Fla. Stat. § 212.08(5)(r)1.a.-Data-center-property.pdf) Cumulative capital investment means the combined total of all expenses incurred by the owners or tenants of a data center after July 1, 2017, in connection with acquiring, constructing, installing, equipping, or expanding the data center. It excludes any expenses incurred in the acquisition of improved real property operating as a data center at the time of acquisition or within 6 months before the acquisition. Fla. Stat. § 212.08(5)(r)1.b.-Data-center-property.pdf)
The DOR form DR-1214DCP asks applicants to disclose the critical IT load for the facility and for each owner and tenant. It also asks whether the property was operating as a data center within the six months before acquisition, to determine which costs count toward the $150 million. Form DR-1214DCP
The five year clock starts when construction begins. If a project takes longer or fails to meet the thresholds, the temporary certificate does not convert to a permanent one, and the exemption is not granted retroactively. The developer would owe tax on purchases made during construction.
How do you apply for and keep the exemption?
The process has two steps. First, you get a temporary certificate. Then, after the facility is built and the requirements are proven, you get a permanent certificate.
Temporary certificate
The AI data center owner files Form DR-1214DCP with the DOR Office of Technical Assistance in Tallahassee. DOR Rule 12A-1.108, Form DR-1214DCP The DOR reviews the application and issues a temporary certificate if it tentatively determines the project will meet the eligibility thresholds. Fla. Stat. § 212.08(5)(r)3.a.
During construction, the temporary certificate allows the owner and its contractors to buy qualifying property without paying sales tax. Each contractor or tenant must get a copy of the certificate from the owner and sign a certificate of entitlement. The seller relies on those documents to not collect tax. Fla. Stat. § 212.08(5)(s)3.d.–e.-Data-center-property.pdf)
Permanent certificate
Once the project is complete and all requirements are met, the certificate holder submits two declarations to the DOR.
- A written declaration from a licensed Florida professional engineer certifying the critical IT load, both for the whole facility and for each owner or tenant.
- A written declaration from a Florida CPA certifying the cumulative capital investment.
The engineer and the CPA may not be professionally related to the AI data center’s owners, tenants, or contractors, except that they may be retained by an AI data center owner to certify that the requirements have been met. Fla. Stat. § 212.08(5)(s)3.b.(I)–(II)-Data-center-property.pdf)
The DOR then issues a permanent tax exemption certificate, Form DR-14DCP. Once issued, the certificate stays valid as long as the facility continues to operate as a data center, subject to DOR review every five years. Fla. Stat. § 212.08(5)(r)3.b.(III)
Five year reviews
Every five years, the permanent certificate holder must submit a new written declaration certifying that the facility still meets the 100 MW total critical IT load and the 1 MW per owner or tenant threshold. The declaration is due within three months before the end of each five year period. Fla. Stat. § 212.08(5)(r)3.b.(III), Fla. Admin. Code R. 12A-1.108
If the DOR determines the facility no longer meets the criteria, it revokes the permanent certificate. Tax, penalty, and interest become due from the date of purchase. The DOR can assess tax within six years after the data center property was purchased, which is longer than the standard three year sales tax statute of limitations. Fla. Stat. § 212.08(5)(r)3.c.
What happens to existing AI data centers below 100 MW?
The new 100 MW threshold has no grandfather clause. An AI data center that got a permanent certificate under the old 15 MW threshold must, at its next five year review, certify that it has 100 MW of critical IT load. Because it cannot, the DOR revokes the permanent certificate. Law firm analysis
When the certificate is revoked, tax becomes due on the exempt property purchased during the exemption period, going back up to six years, with interest and penalty. This is a significant cost for an operator that has been running below 100 MW.
Florida has no operating AI data centers large enough to meet 100 MW. The largest operating facility, Centersquare TPA1 in Hillsborough County, is only 12 MW. Cleanview Many planned projects exceed 100 MW, but existing operators below that size face a new tax exposure.
How does the 2026 large load customer law affect AI data centers?
In 2026, the Florida Legislature passed SB 484, signed on May 7, 2026 as Chapter 2026-65. This law does not change the sales tax exemption itself, but it imposes new electric utility rules for large data centers. SB 484 enrolled text, SB 484 bill analysis
SB 484 requires each public electric utility to file a large load customer tariff with the Florida Public Service Commission by October 1, 2026. A large load customer is one with an anticipated monthly peak load of 50 megawatts or more. The tariff must reasonably ensure that these customers bear their own full cost of service, and that such costs are not shifted to the general body of ratepayers. Ch. 2026-65, § 366.043
The law also prohibits utilities from knowingly serving AI data centers owned or controlled by foreign countries of concern. It preserves local government zoning and land use authority over large load customers. It directs water management districts to deny consumptive use permits if the withdrawal would harm water resources. And it requires an OPPAGA study on large-scale AI data center impacts, due July 1, 2027. SB 484 enrolled text
In practice, these rules mean that a 100 MW AI data center seeking the sales tax exemption must also plan for paying full cost of service electricity rates under a PSC approved utility tariff. Florida Power & Light and Duke Energy have already begun developing large load tariffs. Utility tariff summary, EEI large load tariff summary, Utility tariff summary The Fort Meade project, which proposes 1.2 gigawatts of demand, shows the intersection. The developer needs both the sales tax exemption and a Duke Energy service arrangement under the new tariff rules. As of March 2026, Duke Energy had filed a motion to temporarily pause its rate schedule while the PSC processes the new tariff requirements.
Practical considerations for developers and investors
Developers and investors evaluating a Florida AI data center should keep several points in mind.
Electricity is a large part of the exemption value. The exemption covers electricity used exclusively at the AI data center. If a facility loses the exemption, the ongoing electricity cost becomes subject to sales tax (roughly 7% to 7.5%). That can dwarf the one time tax on equipment. The DOR rule specifically says that separately stated electricity charges from a data center owner to an AI data center tenant at or below the utility rate are exempt. Fla. Admin. Code R. 12A-1.108(4)(a)–(b)
The five year review is the trigger for loss of exemption. A sub 100 MW facility does not lose the exemption on August 1, 2025. It loses it at its next five year review when it cannot certify the new threshold. The review date depends on when the permanent certificate was issued. Developers should determine that date and model the tax impact.
The six year lookback is aggressive. If the DOR revokes a certificate, it can assess tax on all exempt purchases made within the prior six years, not just three. That includes interest and penalties. A fraudulent certificate of entitlement can trigger a tax liability plus a 200% penalty and potential felony charges. Fla. Admin. Code R. 12A-1.108(3)(c), Fla. Stat. § 212.085
The commercial rent tax repeal is a benefit. For tenants in multi tenant AI data centers, the elimination of the 3% to 3.5% tax on lease payments reduces occupancy costs. This can partially offset the loss of the sales tax exemption for smaller operators, though the net effect depends on the facility’s size and lease structure.
The 2026 utility law adds a separate cost layer. The full cost of service tariff for 50 MW and above customers can raise electricity rates compared to blended rates that shift costs. Developers should include these tariff costs in project financial models, independent of the tax exemption analysis.
Water and zoning hurdles now have statutory backing. SB 484 explicitly preserves local control and requires water management districts to protect water resources. The Fort Meade project’s water permit from the Southwest Florida Water Management District was still pending as of April 2026. Lakeland Ledger Project Jarvis in St. Lucie County was withdrawn partly because of the advancing legislation. Florida Data Centers
DOR administrative rules are not yet updated. Rule 12A-1.108 still reflects the 15 MW threshold as of May 2026. DOR rule page The DOR has not published a revised temporary certificate form that incorporates the 100 MW requirement. Applicants should monitor the DOR website for updates and consider filing under current forms while noting the statutory change.
Key takeaways
- Florida’s sales tax exemption for AI data centers is still available, but only for facilities with a critical IT load of 100 MW or more.
- The minimum cumulative capital investment remains $150 million, and each owner or tenant must have at least 1 MW.
- There is no grandfather clause. Existing AI data centers below 100 MW will lose the exemption at their next five year DOR review.
- The exemption covers electricity, so losing it creates a recurring operating cost increase, not just a one time equipment tax.
- The DOR can look back six years to assess tax, penalty, and interest on revoked exemptions.
- Temporary certificates must be applied for by June 30, 2037.
- The commercial rent tax was repealed effective October 1, 2025, which helps tenants but does not affect the sales tax exemption.
- The 2026 law (SB 484) requires full cost of service utility tariffs for AI data centers with 50 MW or more peak load and imposes new water and zoning restrictions.
- DOR administrative rules have not been updated for the 100 MW threshold. Check for new forms and guidance before filing.
Frequently asked questions
Q:Does the exemption apply to electricity?
A:Yes. Electricity used exclusively at a qualifying AI data center is exempt from sales tax. If the exemption is lost, electricity becomes taxable.
Q:What is critical IT load?
A:Critical IT load is the power capacity reserved for running the servers themselves. It does not include power for cooling, lighting, or common areas.
Q:Can a multi-tenant AI data center qualify?
A:Yes. Each tenant must meet the 1 MW minimum, and the entire facility must meet the 100 MW threshold and $150 million cumulative investment.
Q:What happens if my facility cannot meet the 100 MW threshold by the five year review?
A:The DOR will revoke the permanent certificate, and tax, interest, and penalties become due on all exempt purchases made within the previous six years.
Q:Is there any way to keep the exemption for a sub 100 MW facility?
A:No. The statute provides no grandfather clause or waiver. The facility must meet 100 MW at each five year review.
Q:When do I need to apply for the temporary certificate?
A:You must apply before June 30, 2037. However, the earlier you apply, the earlier you can make tax exempt purchases during construction.
Q:Does the 2026 utility law change the tax exemption?
A:No. The sales tax exemption is separate from utility rates. But the utility law can affect the overall cost of operating an AI data center in Florida.
Q:Are there local zoning and water permit requirements for these projects?
A:Yes. SB 484 explicitly preserves local government zoning authority and requires water management districts to deny permits that harm water resources. Expect thorough local review.
Q:What is the current state sales tax rate?
A:The state rate is 6%. Local option surtaxes add typically 1% to 1.5%, depending on the county.
Q:Where can I find the DOR forms?
A:The temporary certificate application is Form DR-1214DCP, available on the Florida Department of Revenue website. The permanent certificate is Form DR-14DCP. DOR forms
