How Property Tax Works

Alexandria County, Virginia operates a property tax system that serves as the primary funding source for essential local services including schools, public safety, infrastructure, and community programs. The county assesses real property annually based on fair market value, with tax bills calculated using a rate per $100 of assessed value. For the 2025 calendar year, the base real estate tax rate is $1.135 per $100 of assessed value, though effective rates can vary depending on your specific location within the county due to special taxing districts and additional assessments.

Property owners should note that Alexandria County's tax system includes various components beyond the base rate, and actual tax bills may differ based on special district assessments, available tax credits (which require application), and supplemental taxes triggered by property changes. The county follows Virginia state law with semi-annual payment schedules, and property owners are responsible for understanding their specific tax obligations based on their property's location and characteristics.

When Are Property Taxes Due?

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Alexandria County are additional property tax bills issued when there are changes to property ownership, value, or classification during the tax year. These taxes are triggered by events such as new construction completion, property transfers, or significant improvements that increase assessed value. The supplemental tax covers the difference between the original tax assessment and the new assessment, prorated for the remaining portion of the tax year.

For example, if you complete a home addition valued at $50,000 in September, you would receive a supplemental tax bill for the increased assessment from September through the end of the tax year. The calculation would be: ($50,000 ÷ 100) × $1.135 × (4 months ÷ 12 months) = $189.17 for the remaining four months of the tax year. Supplemental taxes have separate due dates from regular property taxes and must be paid within 30 days of the bill date.

Example Calculation

Example 1: $300,000 Home

  • Assessed Value: $300,000
  • Available Tax Credit Applied: -$1,500 (estimated homestead credit - requires application)
  • Net Taxable Value: $298,500
  • Annual Tax: $298,500 ÷ 100 × $1.135 = $3,388
  • Monthly Escrow: $282

Example 2: $600,000 Home

  • Assessed Value: $600,000
  • Available Tax Credits Applied: -$2,000 (homestead + senior credit - requires application)
  • Net Taxable Value: $598,000
  • Annual Tax: $598,000 ÷ 100 × $1.135 = $6,787
  • Monthly Escrow: $566

Example 3: $1,000,000 Home

  • Assessed Value: $1,000,000
  • Available Tax Credits Applied: -$1,500 (homestead credit - requires application)
  • Net Taxable Value: $998,500
  • Annual Tax: $998,500 ÷ 100 × $1.135 = $11,333

Escrow & Property Taxes

Most mortgage lenders in Alexandria County require property tax escrow accounts for borrowers with less than 20% down payment or upon request. Your lender collects monthly payments equal to 1/12th of your annual property tax bill plus a small cushion (typically 2 months). The lender pays your property taxes directly to Alexandria County on the due dates: June 17th for the first half and November 16th for the second half of the calendar year.

It's important to review your annual escrow analysis statement and verify that your lender has the correct tax amount, especially after reassessments or when tax credits expire. If your property taxes increase significantly due to reassessment or loss of credits, your lender may require an immediate escrow shortage payment or increase your monthly payment. Contact your lender immediately if you receive a tax bill directly, as this may indicate an escrow account error that could result in late penalties if not resolved quickly.
