To qualify for Pennsylvania’s data center tax incentives, you need certification from the Pennsylvania Department of Revenue under the Computer Data Center Equipment Exemption Program, which requires committing $75 million or $100 million in capital investment over four years (depending on county population), maintaining at least $1 million in annual payroll at the site, and filing the right application on Form REVK-704.1Pennsylvania Department of Revenue. Computer Data Center Equipment Exemption Program Guidelines Once certified, you can buy qualifying equipment free of Pennsylvania’s 6% state sales and use tax. Tenants inside a certified facility can qualify too, on a shorter clock and through a separate annual filing.
What the Exemption Covers and How Long It Lasts
After certification, the owner or operator of the facility presents exemption documentation to vendors and skips the 6% state sales tax at the point of sale on qualifying equipment purchases. There is no pay-then-refund step.2Pennsylvania Department of Revenue. Computer Data Center Equipment Exemption Program
For owners and operators, the exemption runs up to 25 full calendar years after the year the certification application is filed. For tenants, it lasts until the occupancy agreement ends or 10 full calendar years from lease signing, whichever comes first, and never longer than 25 years overall.3Pennsylvania Department of Revenue. Computer Data Center Equipment Exemption Program FAQ
One boundary to be aware of: Philadelphia adds a 2% local sales tax and Allegheny County adds 1% on top of the state rate. The program’s statute and guidelines don’t clearly say whether the exemption reaches those local taxes, so operators in those counties should confirm the treatment with the Department of Revenue before assuming local tax also disappears.
Investment and Payroll Thresholds
The size of your investment commitment depends on where the facility sits. If the county has a population under 250,000, you must invest at least $75 million within four years of the application approval date. In counties above that population, the threshold is $100 million over the same four-year window. Qualifying investment includes servers, networking hardware, cooling infrastructure, and other capital improvements to the facility.
A new build has to reach the threshold from scratch. A refurbished facility is measured on improvements made after the certification date, not on pre-existing value. Alongside the capital number, the operator must keep an aggregate annual payroll of at least $1 million for employees working at the site. Missing either the investment target or the payroll floor puts the exemption at risk.
Equipment That Qualifies and Equipment That Doesn’t
“Computer data center equipment” covers servers, storage devices, networking gear, cooling systems, power distribution units, and related infrastructure installed and used inside the certified facility. Several categories are carved out by statute:4Pennsylvania General Assembly. Pennsylvania Code Title 72 PS Taxation and Fiscal Affairs 9931-D
- Equipment used for proof-of-work crypto-asset mining, whether or not it sits in a certified facility.
- Equipment that generates electricity for sale to a utility, or that generates and sells more than 5% of its electricity outside the certified data center.
- Laptops, handheld devices, and motor vehicles used both inside and outside the data center.
- A telecommunications provider’s data center that primarily serves internal needs and has no retail or wholesale customers being billed for services.
The mining carve-out matters for mixed-workload facilities. Even inside a certified site, hardware dedicated to proof-of-work mining gets no relief, and misclassifying it can produce a back-tax bill on equipment you thought was exempt.
How Tenants Qualify
Tenants can access the exemption without owning the building. To count as a “qualified tenant,” you need a contract with the certified owner or operator for at least 100 kilowatts per month for two or more years.1Pennsylvania Department of Revenue. Computer Data Center Equipment Exemption Program Guidelines
The mechanics involve the host facility, not just you. The owner or operator must submit a qualified tenant list to the Department of Revenue’s program office before October 1 each year, or within 30 days of initial certification. You cannot apply for your own exemption until your name is on that list. If the operator misses the deadline, tenants on that list are disqualified from applying for the year, so the host’s paperwork discipline directly affects your tax bill.
Tenants file a separate exemption application annually and must stay in Pennsylvania tax compliance to keep it. The tenant clock runs no longer than 10 calendar years from the year the occupancy agreement was signed, or the lease expiration, whichever comes first.3Pennsylvania Department of Revenue.

How to Apply for Certification
Applications go to the Pennsylvania Department of Revenue’s Office of Economic Development at 1133 Strawberry Square, Harrisburg, PA 17128. Approved applicants receive a Certificate of Exemption on Form REVK-704, which is the document you present to vendors to buy equipment tax-free.1Pennsylvania Department of Revenue. Computer Data Center Equipment Exemption Program Guidelines Current application materials are on the Department’s Computer Data Center Equipment Program page.
Build the application around what the statute actually asks about:
- A detailed description of the facility’s operations and its physical location.
- Projected investment amounts across the four-year qualification window.
- The number of jobs the project will create or support.
- Technical detail on power capacity and cooling infrastructure sufficient to show the site meets the statutory definition of a data center.
- Tax identification numbers and proof of registration to do business in Pennsylvania.
Architectural plans and financial commitment letters help demonstrate you can hit the $75 million or $100 million threshold. The applicant must be in state tax compliance at the time of application. Tenants file annually, with renewals due before October 1 of the year preceding the exemption year.
Staying Certified
Certification is not one-and-done. If a facility misses the four-year investment target or drops below $1 million in annual payroll, the Department can revoke certification. There is no reporting requirement at the moment of purchase for either buyer or seller, which means real-time state oversight is limited, but the Department can still audit later. Equipment purchases that turn out not to qualify get hit with back taxes plus interest.
Tenants carry a second layer of risk. Your exemption depends on the host’s certification staying in place and on the operator filing the qualified tenant list on time. If the operator loses certification or misses the October 1 list deadline, your tenant exemption goes with it, even if your own operation is fully compliant. Regular check-ins with the operator about the status of the master certification are worth building into your compliance calendar.
Effect on Federal Depreciation Basis
The IRS treats the basis of a purchased asset as its cost, which includes sales tax paid at acquisition.5Internal Revenue Service. Basis of Assets Sales tax you never pay is not part of your federal basis. On a $50 million equipment purchase, the exemption saves $3 million in Pennsylvania sales tax, but your depreciable basis stays at $50 million rather than $53 million, so federal depreciation deductions over the life of the equipment are correspondingly lower. The state savings still exceed the reduced federal depreciation, but the offset belongs in the financial model, particularly at nine-figure investment levels.
