## The human problem

A large local tax base can fund public services while also making a government dependent on one fast-changing industry.

## The prior constraint

Headline revenue figures often omit whether they are audited, budgeted, gross, net of incentives, or concentrated enough to create fiscal risk.

## AI’s actual role

AI demand is one driver of data-center investment; the measured record here is county budgeting and risk management, not a causal estimate of AI’s share.

## The documented result

Loudoun County reports $1.2 billion in data-center real- and personal-property tax revenue for FY 2026. Its FY 2027 adopted budget projects $1.3 billion, or 40% of the county budget. FY 2026 materials show a $119.7 million revenue-stabilization reserve after a $39.7 million contribution.

## Why it may matter

It is a mature example of both a substantial public revenue stream and the need to plan for its volatility.

## Limitations

The figure is budgeted gross tax revenue, not an audited net-benefit calculation.

It does not subtract incentives, infrastructure, schools, services or utility-system effects.

The countywide figure cannot be attributed to a single facility or company.

## Unresolved questions

What are audited receipts after the fiscal year closes?

What public costs and foregone taxes should be netted against the gross figure?

How resilient is the budget to equipment depreciation or tax-policy change?
