The Top 10 Real Estate Taxpayers in Loudoun

Commissioner of the Revenue Robert S. Wertz Jr. has compiled his annual list of the biggest real estate taxpayers in Loudoun.

Wertz’s list contains only properties that are assessed by his office—in other words, not properties owned by public utilities, which are assessed by the State Corporation Commission, or Dulles International Airport.

This year, for the first time since 2015, the biggest property owner in Loudoun by real estate value is not Toll Road Investors Partnership II, the owners of the Dulles Greenway. They have been passed by data center property owner and Digital Realty subsidiary Digital Loudoun 3 LLC.

Before 2015, the biggest property tax payers in Loudoun were the Dulles Town Center Mall and the Verizon campus now known as Quantum Park, formerly the home of MCI WorldCom. Those properties remain some of the biggest and most valuable plots of land in the county, but have fallen behind other major landholders in value.

This is the first year that a data center owner has been the biggest property owner in Loudoun, and this year data centers dominate the list.

Here are the top 10 real property owners in Loudoun, by assessed value:

  1. Digital Loudoun 3 LLC, data centers: $439,746,950
  2. Toll Road Investors Partnership II LP, the Dulles Greenway: $381,830,700
  3. CyrusOne LLC, data centers: $352,823,590
  4. Digital Loudoun Parkway Center North LLC, data centers: $339,144,38
  5. Chelsea GCA Realty Partnership LP, Leesburg Corner Premium Outlets: $270,036,580
  6. Redwood-ERC Ashburn LLC, Ashby Ponds retirement community: $264,781,990
  7. Equinix RP II LLC, data centers: $220,934,560
  8. Solace Ashburn DFG LLC, Quantum Park: $203,165,420
  9. Dulles Town Center Mall LLC, $183,844,810
  10. ICSP LLC, Amazon data centers, $166,616,480

    So what did they actually pay in taxes… land values are one thing, the tax breaks are another…

      downtownres it’s all public records. Just look them up at
      For instance a quick search of number 4 shows they paid $3,130,871.14 in 2018.

        Note that that’s just the property tax based on the assessed value in the article…

        These businesses end up paying a lot more than that with taxes on computer equipment.

        In a nutshell 1M of square footage brings in $22M in tax revenue on average but I’m not sure if the breakdown per company is public records.

        You may want to look at the proposed FY20 budget presentation. Lots of numbers there about data centers and their contribution to the county’s budget.
