Search the Loudoun parcel database
The official parcel database provides ownership and deed references, legal description, sales, values and house characteristics. It supports parcel ID, address and tax-map searches.
- Search by parcel ID for the most exact match.
- Use address when the parcel number is unknown.
- Use the tax-map number for land and subdivision research.
- Compare the assessment date with the sales period used for valuation.
- Open land records separately when you need the recorded deed image.
What the public record contains
Loudoun’s public assessment profile combines ownership, sales and physical data.
- Parcel ID and tax-map number
- Ownership and deed references
- Legal description and acreage
- Sales and assessment values
- House characteristics and land-use information
Parcel data is maintained for assessment and does not replace a survey, title examination or current payoff statement.
Use the correct office
| Task | Responsible office | Best next step |
|---|---|---|
| Value, property characteristics or land use | Commissioner of the Revenue | Use the parcel database or COR services. |
| Tax bill or payment | Loudoun County Treasurer | Use the official payment options. |
| Formal assessment appeal | Board of Equalization | File by the BOE deadline. |
| Deed research | Clerk of Circuit Court | Use land-record research services. |
Loudoun annual valuation cycle
The Commissioner establishes value as of January 1. For 2026, notices reflected market activity during 2025, while the Board of Supervisors set the tax rate later.
Loudoun relief, exemptions and land use
The Commissioner administers relief and deferral programs and maintains special land-use assessment.
- Senior and permanently disabled tax relief
- Disabled-veteran and surviving-spouse exemptions
- Land-use assessment for qualifying agricultural, horticultural, forest and open-space property
- Exempt-status applications for qualifying organizations
- Address-change and ownership-maintenance services
Loudoun assessment review and BOE appeal
Loudoun provides an administrative Application for Review and a later Board of Equalization route.
- Check parcel characteristics, sales and the January 1 valuation basis.
- For 2026, request Commissioner review by March 16.
- If unresolved or skipped, file with the BOE by June 1.
- Submit comparable sales, photographs, appraisal or factual corrections.
- Pay June and December tax installments even while the appeal is pending.
Property-tax bills and payments
The assessment notice is not a tax bill. Loudoun real estate bills are generally due in June and December, and towns may impose an additional town real-estate tax.
Deeds, ownership and recorded documents
The Clerk of Circuit Court maintains land records. The county land-record kiosk helps research deeds and instruments, while parcel data provides assessment references.
Additional Loudoun issues
- Land-use parcels can trigger deferred-tax consequences when use changes.
- Town property can have both county and town taxes.
- Route 28 and other special tax districts may affect a parcel.
- Public-record reports can provide acreage, occupancy and land-characteristic data.
Common lookup and record problems
- Use parcel ID when multiple addresses or units appear.
- Check tax-map formatting when a parcel search fails.
- Do not treat a deed reference in the parcel database as the complete deed.
- If an ownership update is delayed, compare the Clerk recording date with the parcel profile.
- Confirm town tax obligations separately from the county bill.
Buyer and homeowner checks
- Verify land-use status and possible deferred taxes.
- Check county and town tax obligations.
- Review the January 1 assessment and recent sales.
- Search the recorded deed and deed-of-trust chain.
- Confirm whether seller relief or exemptions will terminate.
Local bottom line
Loudoun’s parcel database is unusually detailed, but the correct workflow still separates Commissioner valuation, Treasurer payment, BOE appeals and Circuit Court deeds.
