Virginia sends the bill: what the 2026 data-center tax fights mean for site selection

$1.54 million a year. That is what the Virginia Department of Taxation projected the data-center sales and use tax exemption would cost when Senator Creigh Deeds authored it and Governor Kaine signed it in 2009, with a $150 million minimum capital investment and roughly 50 new jobs required to qualify. By fiscal 2025 the annual cost was $1.6 billion.

The projection missed by 100,000%.

Nobody in Richmond in 2009 was being dishonest. They priced a colocation-era incentive, and hyperscale showed up instead. When the exemption took effect in 2010, the early adopters were colocation and enterprise facilities along the Dulles Technology Corridor, drawn by fiber density around Ashburn that predated the tax break and compounded with it. Then the hyperscalers arrived, and the arithmetic left the solar system. Cumulative exemptions from 2015 through 2024 reached $2.7 billion, which is 53% of every tax incentive dollar Virginia granted in that window, and the exemption grew from a rounding error into the single largest tax incentive in state history. Northern Virginia now hosts more than 200 data centers. The industry side of the ledger is real too: $9.1 billion in annual GDP and 74,000 jobs, per the figures in our Virginia framework file. That is the bargain the 2026 General Assembly is now re-litigating.

What did the JLARC report actually find?

The document that armed everyone is the Joint Legislative Audit and Review Commission report of December 9, 2024, and its headline number is brutal in its simplicity: for every dollar Virginia exempts, the state recovers 48 cents in economic activity and tax revenue. Whatever you believe about induced growth and corridor effects, 48 cents is below the break-even line most incentive programs get judged against, and it handed both camps of reformers the same citation. Fiscal hawks read it as proof the exemption should die. Conditioners read it as proof the exemption should be traded for something.

Handle the number with some care, though. A recovery ratio is a fiscal lens, and it does not capture everything the corridor produced that never lands in a tax receipt. The same JLARC-era accounting that shows 48 cents also sits beside 74,000 jobs and $9.1 billion in annual GDP. Both things are true at once, which is exactly why the legislature split instead of stampeding.

The 2025 session produced neither. Virginia Mercury sized up that year's data-center legislating, in an October 6, 2025 piece, as an object lesson in how bills get stalled. Stalls end.

Which bills matter in the 2026 session?

Per VPM News reporting from January 16, 2026, the marquee vehicles are Delegate Thomas's HB 155 and Delegate McAuliff's HB 503, advancing alongside a cluster of PJM and Dominion-focused energy bills that reshape how large-load costs get allocated. The institutional split is the thing to watch, and the 2026 bills file lays it out: the Senate budget proposed outright elimination of the exemption, while the House passed legislation conditioning it on clean-energy and environmental commitments. A special session was set for April 23, 2026 to resolve the impasse. Our case-file record runs through the scheduling of that session; the resolution deserves its own note. But the direction was already legible before anyone gaveled in.

Here is the part site-selection teams underrate: the tax fight and the energy fight are the same fight wearing different committee assignments. Tax bills draw the headlines. The PJM and Dominion bills move the actual economics of serving the load, because interconnection, capacity-market outcomes, and cost-allocation rules land on the operating statement every month, forever, while the sales-tax exemption lands once per equipment refresh. A team tracking only HB 155 is watching the loud bill and missing the expensive ones.

The best single predictor of which bills advance is not delegate positioning. It is Dominion's testimony. The utility is the central counterparty for Virginia data-center load growth, and its lobbying stance on each vehicle tells you the real legislative trajectory earlier than any floor speech. Watch the witness table, then read the substitutes, because the operative provisions of a Virginia bill get rewritten in committee and the introduced version you skimmed in January is rarely the version that becomes law.

Does state noise change county behavior?

It already did. Legislative attention functions as a permission slip for local tightening, and Virginia's counties read the JLARC report the same way its delegates did. Loudoun County, the heart of Data Center Alley, voted 7-2 on March 18, 2025 to end by-right development and route every new application through special-exception hearings. In August 2025, a judge voided the Prince William Digital Gateway rezonings over procedural defects. Shenandoah and Culpeper are drafting. Each local action cites the same state-level frame, and each one compounds the others: a developer priced out of Loudoun's new discretionary process lands in a neighboring county whose board is reading the same report.

So the honest way to describe Virginia in 2026 is a cumulative repricing event. No single bill changes the market by itself, and neither does any single county vote. The sum changes what "Virginia" means in a site-selection model.

How should a site-selection model respond?

Run the exemption both ways. The exemption lives at Va. Code 58.1-609.3(18), and it is a statutory entitlement rather than a negotiated agreement, which cuts both ways: there is no discretionary approval to lose, and there is no contract to enforce when the statute changes. What the General Assembly gave in 2009, the General Assembly can condition in 2026. So if your Virginia pro forma only works with the full 2009-style exemption intact, you do not have a Virginia pro forma; you have a lobbying position with a cap rate. Model the conditioned scenario, because the House version, clean-energy commitments in exchange for continued exemption, converts a tax question into a procurement question and moves the cost into your power strategy. Then price the process, separately from the tax: the entitlement path in the marquee counties is now discretionary, with hearing calendars and opposition records, and that half of the repricing arrived in 2025 regardless of what Richmond does.

The corridor fundamentals survive any of these outcomes. Twenty years of fiber and interconnection depth, plus a labor pool no other market has assembled. That is why the sky-is-falling read is wrong: Virginia remains the deepest data-center market anywhere even at full freight. What dies is the assumption that Virginia's terms are static.

My bet, on the record: the unconditioned 2009-style exemption never comes back in Virginia, in any session, and by the end of 2027 at least three other states have copied the conditioned-incentive template, trading tax treatment for energy and siting commitments. I also expect the JLARC 48-cent figure to appear in at least one non-Virginia legislature's data-center hearing before then, because numbers that clean travel. If 2028 finds Virginia back at an unconditional exemption and the copycat count at zero, I misread the decade. You are underwriting a Virginia site right now, statistically speaking. Run it at 48 cents and see if it still pencils.
