Property Tax in Loudoun County, 2026

A calculator and field guide for Leesburg-area homeowners — and for anyone considering a move to Loudoun County — including Virginia's 100% assessment ratio, the locality-set Real Estate Tax Relief for Elderly and Disabled (income-based), and the constitutional 100% Disabled Veterans Real Estate Tax Exemption (passed by voters in 2010, effective Jan 2011).

Loudoun County operates under Virginia's distinctive property tax structure. Virginia uses 100% assessment ratio (assessed at full fair market value) and each locality (county OR independent city) sets its own real estate tax rate. Virginia is unique among US states in having 38 independent cities that operate as both city and county for governance and tax purposes.

How the bill is built

Virginia's property tax calculation is straightforward. Step 1: Assessed Value. Loudoun County Office of the Commissioner of the Revenue reassesses your property at fair market value (some localities reassess annually, others biennially or longer). Step 2: Apply rate. Tax = AV × locality rate per $100. Loudoun's combined rate is approximately $0.840 per $100 of AV. Total bill = (AV × rate) / 100. Step 3: Apply exemptions. Disabled veterans receive the full constitutional exemption (since 2011). Seniors and disabled residents may qualify for locality-set Real Estate Tax Relief programs.

Virginia's 100% Disabled Veterans Real Estate Tax Exemption is one of the most-comprehensive in the United States. Approved by Virginia voters in 2010 (Constitution of Virginia, Article X, Section 6-A) and effective January 2011, the exemption provides FULL exemption from real estate tax on the dwelling and surrounding land (typically up to 1 acre) for veterans rated 100% service-connected disabled by the VA. Surviving spouses (unmarried) of 100% disabled veterans retain the exemption. Surviving spouses of US service members killed in action ALSO receive the full exemption regardless of veteran's disability status. No income limit applies.

Real Estate Tax Relief for Elderly and Disabled is locality-set. Each Virginia locality (county or independent city) sets its own income-based real estate tax relief program for residents 65+ and permanently disabled. Income limits and reduction percentages vary widely — Fairfax County provides up to 100% exemption with income under ~$72K; Henrico County provides up to 100% with income under ~$77K; Norfolk provides 25-100% sliding scale. Apply with your locality's Commissioner of the Revenue or Real Estate Assessor.

Independent cities operate as both city and county. Virginia's 38 independent cities (including Virginia Beach, Norfolk, Chesapeake, and Richmond) handle their own assessment, tax collection, and local government services — they are not part of any county. This is unique to Virginia in the United States. The independent city structure means residents pay one combined real estate tax to the city (covering both city AND former-county-equivalent services).

As of April 26, 2026 · From Loudoun County Office of the Commissioner of the Revenue.

Note: Loudoun County is **the wealthiest county in the United States by median household income** — the US Census reports median household income consistently above $156K (highest of all 3,142 US counties) — and one of the fastest-growing counties in the country, doubling in population since 2000. Anchored by Leesburg (the historic county seat) and Ashburn (the modern population center, home to "Data Center Alley"), Loudoun has been transformed from rural farmland to a prosperous DC exurb in less than 30 years.

Note: Loudoun County effective property tax rates run approximately 0.875% — among the **lowest rates in Northern Virginia** despite high home values (median ~$659K). The Real Estate Tax Rate is ~$0.84 per $100 of AV, plus modest fire/rescue and stormwater levies. Loudoun has a Land Use Assessment program that allows agricultural land to be assessed at use value rather than market value — historically important for the western county's horse country.

Note: For relocation buyers: Loudoun represents the high-end DC exurb choice — newer housing stock (much of it 2000s-2020s construction), top-rated public schools (Loudoun County Public Schools is consistently one of the highest-rated districts in Virginia), and lower property tax rates than Fairfax. The trade-off is longer DC commutes via Dulles Toll Road or Metro Silver Line (extended to Ashburn in 2022). Loudoun's "Data Center Alley" (Ashburn / Sterling) hosts ~70% of all internet traffic globally.

Tax relief and exemptions for 2026

Virginia's homeowner tax relief is unusual: there is no statewide homestead exemption (unlike most US states). Instead, each locality (county or independent city) sets its own income-based Real Estate Tax Relief for Elderly and Disabled program. The constitutional 100% Disabled Veterans Real Estate Tax Exemption (since 2011) is statewide.

Disabled Veterans Real Estate Tax Exemption (constitutional)

Approved by Virginia voters in November 2010 (Constitution of Virginia, Article X, Section 6-A) and effective January 1, 2011, this is among the most-comprehensive disabled-veteran property tax exemptions in the United States. Veterans rated 100% service-connected disabled by the VA — including 100% individual unemployability ratings — receive full exemption from real estate tax on their primary residence (dwelling and surrounding land, typically up to 1 acre; localities can set higher limits). No income limit applies. Surviving spouses (unmarried) of 100% disabled veterans retain the exemption. Surviving spouses of US service members killed in action ALSO receive the full exemption, regardless of veteran's disability rating.

Apply with your locality's Commissioner of the Revenue or Real Estate Assessor with VA documentation of disability rating. Application is typically a one-time process; the exemption renews automatically unless circumstances change.

Real Estate Tax Relief for Elderly and Disabled (locality-set)

Each Virginia locality sets its own income-based program for residents 65+ or permanently disabled. Income limits and reduction percentages vary widely:

Fairfax County: up to 100% exemption (income under ~$72K), sliding scale up to ~$100K
Arlington County: up to 100% (income under ~$99K)
Henrico County: up to 100% (income under ~$77K)
Norfolk: 25-100% sliding scale (income under ~$67K)
Virginia Beach: up to 100% (income under ~$80K)

Apply annually with your locality's Commissioner of the Revenue or Assessor. Most localities require proof of age, income, and asset documentation.

Independent City structure

Virginia is unique among US states in having 38 independent cities that operate as both city and county for governance, assessment, and tax collection purposes. Independent cities (including Virginia Beach, Norfolk, Chesapeake, and Richmond among the largest) handle their own assessment and collect a single combined real estate tax — there is no separate "county" portion. This contrasts with most states where city residents pay both city and county property taxes. The independent city designation dates to 1871 and reflects Virginia's Reconstruction-era urban governance reforms.

Appealing your assessment

Virginia's appeal process runs through the local Board of Equalization (BOE) — each locality has its own. Homeowners file an Application for Review with the Loudoun County Office of the Commissioner of the Revenue typically within 30-90 days of receiving the annual reassessment notice (deadlines vary by locality). The BOE holds hearings during the assessment cycle — homeowners can present comparable sales, recent appraisals, or independent appraiser testimony. BOE decisions can be appealed to the local Circuit Court within 1 year. Some localities (including Fairfax) reassess annually; others reassess every 2-6 years.

About Loudoun County

Beyond the property tax — a few things you might not know about the place.

Weird fact

Loudoun County contains **the highest concentration of data centers in the world** — Ashburn alone hosts approximately 70% of all internet traffic globally. The phenomenon began when AOL chose Dulles in the 1990s for its servers; the resulting fiber optic infrastructure became the backbone for cloud computing. Today Loudoun has 25+ million square feet of data center space (a typical data center is 200,000-500,000 sq ft, so this represents ~50-125 buildings), generating an estimated $700+ million in annual property tax revenue — by far the largest line item in the county budget and the reason Loudoun real estate taxes are unusually low for Northern Virginia.

Hometown hero

Robert E. Lee

The Confederate general's family roots run through Loudoun County — Lee's family owned Stratford Hall (in nearby Westmoreland County) but Lee himself spent significant time at Sully Plantation (now Sully Historic Site, in eastern Loudoun) and at the Lee family estate at Arlington House (now in Arlington County, the present-day Arlington National Cemetery). The Sully Historic Site is one of the most-significant 18th-century plantation house museums in Northern Virginia.
