Effective for the 2026 tax year, Loudoun County has introduced new classification changes and updated assessment schedules for several property categories under its Business Tangible Personal Property (BTPP) tax. Businesses must reflect these changes when filing returns for the March 1, 2026 deadline.

Taxpayers should have received official notice of these changes from Loudoun County in late December 2025. If you haven’t, review county resources immediately to ensure compliance.

Who is Affected

These changes impact businesses with tangible assets in Loudoun County, including:

What Changed

Taxable value continues to be calculated as a percentage of an original capitalized cost, which includes installation, freight, and similar expenses. According to Loudoun’s memo, key updates include:

  • Updated Percentages for Several Categories: Assessment schedules for computer equipment in a data center (DE), heavy equipment (HE), and machinery and tools (M&T) have been updated.
  • New Classification Structure: General computer equipment (CE) and furniture/fixtures (FF) were consolidated into business equipment (BE). This category now has its own assessment schedule.
  • Expanded Reporting Requirements: Businesses must now summarize costs by year of acquisition for the current year plus the prior five years (or the current year plus the prior six years for heavy equipment).

These changes will generally increase assessed values for newer assets and may affect how businesses classify and report assets. Exclusions still apply, including inventory, certified pollution control equipment, application software, and household goods not used for business.
