Virginia’s Data Center Tax took effect on July 1, 2026, adding a $0.011 charge for every kilowatt-hour of electricity used by data center operators. The measure created a direct operating-cost line tied to power consumption, while Virginia kept the larger sales and use tax exemption for qualifying data center equipment in place.
The design matters because it does not tax data center revenue, server count, square footage, or lease value. It taxes electricity use. That makes the cost easier to model than many business taxes, but it also places the burden most directly on facilities with high utilization, dense compute loads, and limited ability to shift power demand. For operators, the financial effect is not just the statutory rate. It is the way that rate interacts with existing power contracts, utility billing systems, self-generation, customer pass-through language, and expansion planning.
What The Data Center Tax Changes
Effective Date And Collection Structure
The tax applied from July 1, 2026. It covers electricity supplied by utilities and electricity generated by a data center for its own use. For utility-supplied power, the tax is collected monthly through the utility. For self-supplied power, the data center is responsible for the direct remittance. That structure reduces the chance that operators can avoid the charge simply by changing procurement methods, although the exact billing and compliance workload can differ by facility.
The tax is scheduled to expire on June 30, 2028. It is also capped at $600 million in collections per year. Those two limits are material for financial planning. A two-year tax can still affect capital allocation, but it is different from a permanent change in the cost base. Operators evaluating multi-decade campuses may treat the charge as a near-term policy cost while still watching whether future budgets extend, revise, or replace it.
Data Center Tax Cost Mechanics
The Data Center Tax is narrow in one sense and broad in another. It is narrow because it is measured only by kilowatt-hours. It is broad because nearly every core function in a data center consumes electricity: compute equipment, storage, networking, cooling, power conversion, lighting, controls, and support systems. The statute therefore affects both the information technology load and the facility systems that keep that load running.
A facility using 10 million kWh per year would face about $110,000 in annual tax. A facility using 50 million kWh would face about $550,000. A facility using 100 million kWh would face about $1.1 million. These examples follow directly from the $0.011 per kWh rate. The calculation is simple, but the business effect is not uniform. A wholesale colocation site, a hyperscale campus, and an enterprise facility may allocate that new cost in different ways depending on contract terms and metering arrangements.
Cost Exposure By Electricity Use
Annualized Facility Examples
The first-order calculation is consumption multiplied by the tax rate. The table below shows the arithmetic for common facility-scale examples provided in the research record.
| Annual Electricity Use | Tax Rate | Estimated Annual Tax |
|---|---|---|
| 10 million kWh | $0.011 per kWh | $110,000 |
| 50 million kWh | $0.011 per kWh | $550,000 |
| 100 million kWh | $0.011 per kWh | $1.1 million |
This cost is small compared with the full capital expense of a large data center, but it is not immaterial. Power is already one of the largest controllable operating inputs for these facilities. A per-kWh charge attaches to every operating hour, so it increases with utilization. A lightly used facility pays less. A highly used facility pays more. That linkage may matter for customers running dense workloads where power draw is the main operating constraint.
Contract And Budget Effects
Operators will need to check how the tax is classified under customer contracts. Some agreements allow direct pass-through of taxes or utility charges. Others may treat power as part of a bundled service fee. If the tax cannot be passed through, it can reduce operator margin. If it can be passed through, it raises the effective cost to tenants or enterprise users.
Self-generation does not remove the exposure because the tax also applies to electricity generated by the data center itself. That detail is significant for facilities that use on-site generation for reliability or cost management. The tax base follows consumption, not the source of the electrons.
The Exemption Trade-Off
Equipment Incentives Remained In Place
Virginia retained the sales and use tax exemption for qualifying data center equipment, including servers, network gear, chillers, and backup generators. The exemption remains valid through June 30, 2035, with possible extensions to 2040 or 2050 if investment and employment thresholds are met.
That decision is central to the state’s policy balance. The new electricity tax raises revenue from operating consumption, while the equipment exemption continues to reduce the tax cost of building and refreshing facilities. According to state economic analysis, eliminating the equipment sales and use tax exemption while keeping other conditions unchanged would have reduced net revenues by nearly $1.3 billion over five years, based on investment and employment in fiscal years 2024 and 2025, as described in the Virginia report on data center tax exemptions.
Why The Trade-Off Is Financially Uneven
The exemption and the electricity charge affect different decisions. The exemption lowers the cost of capital equipment. The electricity charge raises the cost of operation. A new campus with heavy equipment purchases may still find the retained exemption financially meaningful. A mature facility with high utilization and fewer near-term equipment purchases will feel the power-linked charge more directly.
Virginia’s forgone revenue from the sales and use tax exemption was about $1.3 billion in fiscal year 2024 and about $1.9 billion in fiscal year 2025. The new electricity tax is expected to raise up to $600 million per year under the fiscal 2026-2028 budget period. That comparison shows the scale of the policy choice: the state added a recurring consumption tax but did not remove the larger incentive structure tied to equipment investment.
Local Revenue And Grid Cost Context
Fairfax County Shows The Local Fiscal Link
Local governments have a separate fiscal interest. Fairfax County reported that data centers contributed about $110.6 million to its General Fund for tax year 2026, equal to 1.9% of total General Fund revenue, according to the county’s data centers page. That figure does not settle the statewide cost-benefit debate, but it shows why localities weigh data center policy through both revenue and infrastructure lenses.
Data centers also bring power-system planning questions. The tax is framed around electricity consumption, so it sits beside broader debates about who pays for grid upgrades, capacity needs, and related infrastructure. Readers tracking that issue can compare the tax design with related analysis of grid cost rules for Virginia data centers.
Who Bears The Cost
The immediate legal burden falls on data center operators, but the economic burden may be shared. Utilities collect the charge for utility-supplied electricity. Operators may absorb it, allocate it to tenants, or include it in future pricing. Customers with contracts that separate electricity charges from base rent may see the effect more clearly than customers paying bundled rates.
The uncertainty is not the rate. The rate is explicit. The uncertainty is incidence: who ultimately pays after contract terms, market conditions, and competitive pressures are applied. In markets where customers can choose between Virginia and another location, even a measurable tax may be only one factor among latency, land, power availability, permitting, equipment incentives, and access to skilled contractors.
Virginia Data Center Tax Cost Implications
Planning Priorities For Operators
The Data Center Tax does not replace normal energy procurement analysis. It adds a fixed per-kWh overlay that should be included in operating models from July 1, 2026, through June 30, 2028. Operators should model the charge by facility, not just at the corporate level, because utilization rates and customer cost-recovery terms can differ sharply across sites.
Finance teams also need scenario planning around the $600 million annual cap. The cap limits statewide collections, but individual operators still need to assume the statutory rate unless guidance or billing treatment indicates a different outcome. For board materials or customer briefings, the most defensible approach is to show the rate, the usage base, the resulting annual exposure, and the contract treatment separately. Teams preparing those presentations may find a related resource in the same network, accessible at FreeSlideshows, useful for organizing assumptions into clear slides.
What The Policy Does Not Answer
The policy does not determine whether each project remains financially attractive. It does not provide a complete allocation method for grid costs. It does not measure the local land-use impact of each campus. It also does not resolve whether the tax will end as scheduled on June 30, 2028. Those are separate commercial and policy questions.
The clearest financial insight is that Virginia chose a middle path. It imposed a direct charge on electricity consumption while preserving the equipment exemption that has supported data center investment. For data center operators, the near-term action is practical: measure kWh exposure, review billing and self-generation procedures, map contract pass-through rights, and update project economics with the new operating-cost line. For policymakers, the central test is whether the revenue raised by the charge offsets public cost concerns without materially weakening the investment base supported by the retained exemption.
