North Carolina just repealed the sales-tax exemption on data center electricity and left the exemptions on servers, chillers and construction materials untouched. That split is the entire story.
The subsidy that lowers the cost of building AI capacity survived intact. The subsidy that lowered the cost of running it is gone. Building is a one-time event with a ribbon-cutting. Running is a meter that never stops — and for most enterprises in 2026, the thing on the other end of that meter is inference.
What North Carolina Actually Repealed
The 2026 state budget signed by Governor Josh Stein eliminated one line from the data center incentive package and left the rest standing. Per Data Center Knowledge, the budget "repeals the sales and use tax exemption for electricity purchased by qualifying data centers and leaves in place exemptions covering qualifying equipment and other eligible investments under existing statutes." The repeal took effect with the budget's passage.
North Carolina taxes electricity at the 7.00% combined general rate, per the Department of Revenue. That rate now applies to every kilowatt-hour a qualifying data center burns in the state.
Stein was blunt about the reasoning. "The legislature agreed to remove the data center's sales tax exemption for electricity, so you and I will no longer be subsidizing their energy consumption," he said, per Carolina Journal. Senate leader Phil Berger was more transactional: "It's what we were able to agree to," he told WFAE.
Here is why "what we were able to agree to" is the load-bearing phrase. WFAE's reporting put a value on each piece of North Carolina's incentive stack:
| Exemption | Value today | If all announced projects are built |
|---|---|---|
| Electricity | ~$20M/year | ~$160M/year |
| Equipment replacement | $25–37M/year | $205–308M/year |
| Construction materials | — | $1.5–2.3B avoided |
The state repealed the smallest one. The Fiscal Research Division scores it at $21.4 million in FY 2026-27, rising to $28.6 million by FY 2030-31 — real money for a general fund, a rounding error against the $1.5–2.3 billion in construction-materials tax the state is still forgoing.
The industry read it exactly this way. Dan Diorio of the Data Center Coalition told Data Center Knowledge that while the electricity exemption "was an important part of the overall data center sales tax exemption program, we are happy that this budget provides certainty for data centers to continue investing in North Carolina." That is not the statement of a lobby that lost.
To qualify for the surviving exemptions, an operator still needs $75 million of investment over five years and must offer health insurance. Nothing about that test changed.
The Bill: Roughly $48,000 per Megawatt per Year
The arithmetic is small per megawatt and large per campus. The Tax Foundation models a representative $1 billion facility at 32 MW of utilization drawing about 0.28 TWh a year, and in its steady-state comparison, Charlotte, North Carolina showed $0 in electricity taxes — against $1,653,140 a year in Atlanta, where Georgia taxes data center power.
That $0 line is now obsolete. At North Carolina's average industrial retail price of 7.81 cents per kWh (EIA data via YCharts, 2026), 0.28 TWh is roughly a $21.9 million annual power bill. Seven percent of that is about $1.5 million a year — call it $48,000 per megawatt per year, or $4.8 million a year on a 100 MW campus.
Treat that as an order of magnitude, not a quote, because two assumptions do the work. The Tax Foundation's facility draws 0.28 TWh from 32 MW, which is essentially continuous full-power operation — at a 50% load factor the same campus pays half. And hyperscale and large colocation loads buy under negotiated industrial tariffs rather than the state average, so your effective rate will differ. The structure is what matters: this is a percentage of a bill that scales linearly with how hard you run the machines, and it recurs every month for the life of the facility.
Compare that to what North Carolina kept. The construction-materials and equipment exemptions are worth far more in absolute dollars, but they are paid once at build and once per refresh cycle — the Tax Foundation's model assumes a five-year server replacement cadence. A developer capitalizes those. Nobody capitalizes a power bill.
Why the Tax Lands on Inference, Not Training
An electricity tax is a tax on utilization, and utilization in 2026 is overwhelmingly inference. Deloitte's TMT Predictions 2026 forecasts that inference — running models, not training them — will account for two-thirds of all AI computing power this year, with nearly half a trillion dollars of new data centers built to serve it.
The mechanism is cumulative energy, not instantaneous draw — a training run pulls full power for as long as it lasts, and pays the same 7% while it does. What differs is how long it lasts. Training is a project: a cluster is stood up, a run completes, the asset is written down over years. Inference is a service: it answers requests at 3am on a Tuesday, its load factor is set by your traffic, and it never finishes. Two-thirds of the kilowatt-hours is two-thirds of the tax, and the two-thirds is the side of the ledger that never closes.
That is a strange place for the incentive to have landed, given that idle capacity is already the industry's dominant waste line — our earlier reporting on GPU utilization covered how little of the installed fleet is doing useful work. North Carolina has now put a surcharge on the fleet that is busy and left the one that is idle exactly as subsidized as before. As a matter of tax design, that is backwards. As a matter of your operating budget, it is a line item.
For most enterprise buyers this arrives indirectly, through one of two paths:
- Colocation and wholesale leases. Power is typically billed as a metered pass-through, and the pass-through language routinely includes new or increased taxes, levies, surcharges and government charges on the supply or consumption of power. If your agreement has that clause, a repealed state exemption reaches your invoice mid-term with no renegotiation, no notice period, and no leverage.
- Managed inference. If you buy through Amazon Bedrock, Google Vertex AI or Azure AI Foundry, the provider absorbs it and you never see the line. It shows up later, blended into regional price differences and capacity siting decisions you don't control.
The first group can read the clause today. The second group cannot, which is its own kind of exposure.
Two Dozen States Are Running the Same Play
North Carolina is the cleanest example of a pattern, not an outlier. Bloomberg Tax counts two dozen states that introduced bills this year to repeal or substantially curtail data center tax breaks, with at least nine considering full repeal, against 38 states that currently offer incentives. Virginia's exemption alone reached nearly $2 billion in fiscal 2025, up from $136 million in fiscal 2022.
"The idea that states would repeal the sales tax exemption would've been unthinkable three years ago," Caleb Max of the National Artificial Intelligence Association told Bloomberg Tax. "Now, it's par for the course."
What the 2026 actions share is not the target — it is the timing of the target. Each one removes a recurring subsidy and preserves the one-time one:
- Minnesota stopped exempting electricity purchases on July 1, 2025, per the Department of Revenue, while extending the equipment and software exemptions to 2042. In their place, large-scale centers now pay an annual fee of $2 million to $5 million into low-income energy conservation programs, per GovTech — and that fee is scaled to peak demand, which prices a training cluster's spike rather than an inference fleet's steady draw. Same instinct, opposite incidence.
- Washington went after the other recurring line. Under SB 6231, effective July 1, 2026, refurbishment and equipment replacement — including installation labor — lost the exemption and now pay the state's 6.5% rate. First builds and initial server installs stay exempt. "Data centers became major users of electricity and created fewer permanent jobs than originally anticipated," the state's Office of Financial Management testified. Senator Chris Gildon's dissent named the real constraint: "It is going to put our state in a competitive disadvantage to other states, particularly Oregon, which is our neighbor."
- Arizona froze new applications entirely from July 1, 2026 through June 30, 2029 under HB 4168/SB 1861 — the longest such pause in the country, worth roughly $38 million a year by lawmakers' estimate, per the Arizona Capitol Times. Existing certifications continue.
- Illinois paused new credits on July 1, and Ohio halted new exemption requests in late May while a select committee studies the industry, per MultiState — Ohio's already-approved centers reported $27.2 billion of capital investment in 2025.
- Georgia kept its exemption after projections showed it costing $2.5 billion in fiscal 2026 — 664% above the prior estimate, and New York is weighing S8546, a fee explicitly indexed to electricity consumption, per Newsweek. Texas has directed regulators to make data centers cover their own interconnection costs, with a sales-tax phase-out queued for the 2027 session.
North Carolina may not be finished either. In June, Stein proposed sunsetting every data center sales tax exemption by the end of 2032, closing new applications at the end of 2026, per WUNC. The state estimates it would otherwise forgo $1.5–2.3 billion during construction and roughly $450 million a year afterward. A separate bipartisan bill, H 1213, would have repealed the software and electricity exemptions outright and struck the statutory definitions of "qualifying datacenter" — it was filed April 30 and has not moved. The budget did the electricity half.
If you are modeling a 15-year facility life in any of these states, the incentive you underwrote is now a variable.
The Case That None of This Matters
The strongest counterargument is that $48,000 per megawatt is noise, and it deserves a fair hearing.
Against an AI data center's capital cost — measured in millions of dollars per megawatt — and against the roughly $683,000 per megawatt per year the power itself costs at that same rate and duty cycle, a 7% tax on the energy line is low single digits of total cost of ownership. Neil Osnato of Persistence Analytics Group made exactly this point to Data Center Knowledge: for AI-scale facilities, power availability and delivery timelines matter more than tax incentives. He is right. No CTO has ever chosen a region because the sales tax on electricity was zero; they choose it because someone can actually deliver 100 MW before 2029, a constraint we've written about before.
The second counterargument is that the tax is dwarfed by what the utility is about to do anyway. In late June, Duke Energy proposed a large load tariff to the North Carolina Utilities Commission: a 75% minimum take on maximum potential energy use, a 10- or 15-year minimum contract term, and a 50 MW threshold, per Canary Media. Duke has raised its 2035 large-customer forecast to 8 gigawatts in the Carolinas, up 2 GW year over year, and is justifying 9.7 GW of new gas plants with it. A commission decision is expected this fall.
A 75% minimum take is a far bigger repricing than a 7% sales tax. If it clears, you pay for three-quarters of your maximum potential energy use whether you draw it or not — which converts a variable cost into a fixed one and punishes exactly the burst-and-idle pattern most enterprise inference actually has.
But notice what both instruments have in common. The tax and the tariff both price operation. Neither touches construction. That is the signal. Two independent actors — a legislature and a regulator — reached for the operating side of the ledger in the same quarter, and the capital side came through both untouched. When the tax and the utility agree, that is not a coincidence you should model as noise.
Why This Direction of Travel Is One-Way
Nearly every state in the 2026 wave gave the same reason, and it was rarely revenue. It was the grid. Washington's finance office said data centers "became major users of electricity and created fewer permanent jobs than originally anticipated." Minnesota routed its new fee to low-income energy programs. Illinois's governor asked for residential ratepayer protections. North Carolina's Representative Matthew Winslow framed it as: "Data centers bring economic opportunity, but they must not come at the expense of our ratepayers, our water resources, or our energy reliability."
That is a durable political coalition, and it means the direction of travel is one-way. Nobody is running for office on restoring a power subsidy for AI infrastructure while residential bills climb. The $725 billion capex cycle that made these facilities politically visible is the same cycle that made them politically expensive.
The practical consequence: assume the electricity line gets worse in most jurisdictions over your contract term, and assume the equipment line stays roughly where it is. Price accordingly.
What to Check Before Your Next Renewal
This Week:
- Pull your colocation or wholesale lease and find the power clause. You are looking for whether power is billed at cost as a metered pass-through, and whether the pass-through definition includes taxes, levies, surcharges and government charges imposed after the effective date. If it does, North Carolina's repeal already applies to you and no one had to call you.
- Ask your provider, in writing, whether the exemption repeal is being passed through and from which billing cycle. Get the answer in email. A pass-through you learn about from an invoice is a pass-through you cannot contest.
- Identify which of your workloads are location-portable. Batch scoring, embeddings regeneration, offline evals and fine-tuning can move or reschedule. Interactive inference behind a customer-facing SLA cannot. Those two lists have very different exposure to a per-kWh tax.
This Month:
- Add the electricity tax regime to your site-selection checklist, separately from the equipment regime. They now diverge by state, and the electricity column is the one that compounds. Score the state, not the cloud region's marketing name.
- Model your inference load factor explicitly. A tax on energy is a tax on duty cycle. If your fleet runs at 80% around the clock, you carry roughly four times the exposure of one that runs at 20% — and you should already know that number for FinOps reasons regardless of the tax.
- If Duke's large load tariff affects you, file or join a comment before the commission's fall decision. A 75% minimum take negotiated without customer input becomes the template other utilities copy.
Before Renewal:
- Negotiate a cap or a notice requirement on tax pass-throughs. You will not get the pass-through removed — no operator will absorb an open-ended tax exposure — but a 30-day notice requirement and a right to audit the calculation are both winnable and neither is usually in the first draft.
- Re-run your build-versus-buy and on-prem math with the new operating cost. Self-hosted inference concentrates the electricity line onto your own balance sheet; managed endpoints socialize it. That trade has shifted before on smaller inputs than this.
The Bottom Line
When a subsidy gets unbundled, the piece they keep tells you what the state actually wanted. North Carolina wanted the construction jobs, the property tax base and the announcement — so the $1.5–2.3 billion construction-materials break survived. It did not want to pay the power bill for a machine that runs forever, so the $20 million electricity break died. That is not a universal law of tax policy — most states, North Carolina among them, still exempt electricity sold to manufacturers and have for decades. What makes data centers different is that this operating subsidy shows up on a residential utility bill.
For an enterprise buyer, that reframes the question. You have been evaluating regions on capacity, latency and delivery timeline. Add a fourth column, and make it the one that recurs: what does it cost to run a megawatt here in year seven, under the tax and tariff regime this legislature is heading toward — not the one that closed the deal.
The servers are still tax-free. The electricity is the part you actually buy.
