Data Centers Account for Major Share of Tax Revenue in Loudoun County

Billions of dollars have been invested in facilities supporting artificial intelligence infrastructure across the United States. In some communities these projects have prompted debate over electricity demand, water consumption, land use and local services. In Loudoun County, Virginia, data centers have expanded the local tax base over several decades.

Loudoun County contains the highest concentration of data centers in the world, an area often referred to as Data Center Alley. Northern Virginia as a whole holds roughly 13 percent of global operational data center capacity. County officials and budget records show that data centers contribute between 40 and 50 percent of property tax revenue in recent fiscal years.

Jared Walczak, vice president of state projects at the Tax Foundation, stated that data centers supply about 45 percent of all local tax revenue in Loudoun County. He said this share has allowed property tax rates to remain lower than they would be without the facilities. According to Walczak, the average homeowner pays approximately $5,800 less annually in property taxes than would otherwise be the case. Data centers occupy roughly 3 percent of the county’s land area.

Loudoun County budget documents align with the 40-to-50 percent revenue range cited by Walczak, confirming the scale of the contribution through property taxes alone. The county’s tax base has grown with the addition of these facilities, which state and local governments had previously sought to attract.

The same expansion has generated discussion about effects on electricity costs and infrastructure. Some residents and candidates in the 2026 midterm cycle have raised questions about whether increased power demand could raise utility rates or require additional public investment. Walczak has argued that the property-tax effects are measurable while energy-price impacts depend on how new generation and transmission costs are allocated. He stated that data-center customers typically fund incremental infrastructure and that higher overall usage can distribute fixed grid costs across more customers.

Northern Virginia has recorded electricity prices below the national average in recent periods, according to Walczak. He noted that regions with substantial data-center development have not shown uniform increases in residential rates relative to other parts of the country. No independent analysis of Loudoun-specific rate changes or infrastructure cost allocation is presented in the available reporting.

Virginia has maintained its position as a leading data-center market for more than two decades. Continued construction tied to artificial-intelligence workloads has added to existing capacity in the region. County records indicate that the facilities remain a primary source of local revenue even as land-use and service questions continue to be discussed in public meetings and election campaigns.
