Find the Loudoun Parcel, Verify the Value, and Complete the Tax Task

Search Loudoun County real estate by street address, 12-character Parcel Identification Number or tax map number, then open the detailed record to review ownership, deed references, legal description, sales, land, house characteristics, 2026 assessment values, land-use status, special tax districts and payment history.

This guide goes beyond a basic directory link. It explains the actual iasWorld search quirks, how to use WebLogis, what Virginia’s 100% fair-market assessment means, the current $0.805 real-property tax rate, the December 7, 2026 payment deadline, expired 2026 appeal dates, senior and disability relief, land-use rollback risks and the separate Clerk system for recorded deeds.

Use the right Loudoun office. The Commissioner of the Revenue determines real-property assessments and administers relief. The Treasurer bills and collects taxes. The Clerk of the Circuit Court maintains deeds and land records. GIS/WebLogis helps locate parcels but does not establish legal boundaries.

Search the official Loudoun County Real Estate Tax, Assessment & Parcel Database by property address, Parcel ID Number or tax map number. Open the correct parcel, verify its 12-character PIN and physical location, then save the assessment, tax-district and deed information before moving to payment, GIS, relief or land records.

Secret weapon: portal quirks

iasWorld search tricks that save failed searches

Loudoun iasWorld portal behavior
Portal behavior
What to do
Why it matters
Street-type matching
Leave RD, ST, DR, CT, LN, AVE and similar suffixes off the first search.
The official portal says address searches work best without the street suffix.
Wildcard
Use * before, after or within a partial string.
Useful for uncertain street spelling, PIN fragments and tax-map groups.
PIN length
Expect a 12-character Parcel ID.
A missing or extra digit can point to the wrong record or no result.
PIN punctuation
Enter the PIN with or without dashes.
The portal accepts both formats.
Range search
Use Advanced Search for criteria such as year-built, tax-map ranges or stories.
The ordinary tabs are not designed for range searches.
Data timing
Check the “Data Current as of” date shown in the portal.
The county states parcel data is updated weekly rather than continuously.
Condo parking / garage
Search for separate parcel IDs if the unit has an assigned taxable garage or parking space.
Loudoun warns these may be separately assessed parcels.
Special districts
Inspect Billing District, Special Ad Valorem Tax District and Special Project District.
The base county tax rate may not be the parcel’s entire tax burden.
Wildcard examples: `*woodland` can return addresses on a street containing Woodland, while a PIN search such as `123*` can return parcels beginning with that PIN sequence.
Map-print quirk: WebLogis currently warns that its Print Map tool does not work with 2025 imagery. If you need the built-in print function, the system directs users to 2017 imagery or its alternative printing options.
Failed-search recovery

No Loudoun parcel found? Diagnose the identifier first

Exact address fails Remove the street suffix and search the number plus main street name.
Street spelling is uncertain Use the official * wildcard rather than guessing several exact spellings.
PIN returns nothing Confirm all 12 characters and try the same number without dashes.
Condo result looks incomplete Search the residence and any separately assessed garage or parking-space parcel.
Parcel was split recently Search the prior PIN, map location and Parcel Tracking information.
Parcels were combined Review former parcel records and confirm the active tax account with the Commissioner.
Recently purchased property Remember the annual notice is sent to the January 1 owner; check the deed and current parcel profile separately.
Address has changed Use WebLogis or Mapping staff to identify the PIN from the physical location.
Buyer warning for recently changed parcels: Loudoun’s official land-record research notice tells purchasers to investigate parcels divided or combined within the previous 36 months to ensure all taxes and levies are paid. It also warns buyers to review parcel history for prior Land Use valuation because deferred taxes may later become due.
Parcel-identification call script “I am trying to identify the active real-estate parcel at [address/general location]. I have [old PIN, tax-map number, deed reference or former owner]. Can you confirm whether it was divided, combined, deactivated or assigned a new PIN?”

2026 assessment

Loudoun real estate is assessed at 100% of fair market value

The assessed value is the county’s market-value estimate

Virginia real estate is assessed at 100% of fair market value. Loudoun’s 2026 assessment represents estimated market value as of January 1, 2026 and reflects market activity examined from 2025.

The assessment is not the tax bill. The Board of Supervisors separately sets the tax rate, and a parcel may also have special district taxes, incorporated-town taxes, approved relief or land-use valuation.

Valuation date January 1, 2026

2026 assessment date.

Online release February 3, 2026

2026 assessments became available online.

Notice mailing From February 6

Assessment notices began mailing to property owners.

MARKET DATA 2025 activity JAN. 1 VALUE 2026 fair market 100% ASSESSED Virginia standard $0.805 RATE per $100 TAX BILL + districts / relief

Example: $800,000 regular-district assessment

Step 1 · Assessment

$800,000 at 100% fair-market assessment.

Step 2 · Divide by 100

8,000 taxable $100 units.

Step 3 · Multiply by $0.805

Estimated county real-property tax: $6,440 before special districts, town taxes, relief or adjustments.

If the value seems wrong: first check living area, finished basement, bathrooms, acreage, structures, condition and sale history. Loudoun specifically tells owners to call for an inspection when physical property characteristics are inaccurate.
2026 tax calendar

The next 2026 Loudoun real-estate deadline is December 7

First half June 5, 2026

First-half real-estate taxes were due on this date.

Second half 2026 December 7, 2026

The county’s 2026 assessment release identifies this as the second bill due date.

Standard calendar December 5

Loudoun’s normal second-half date is December 5; the exact 2026 bill controls.

Use the actual 2026 bill. Loudoun’s standing tax calendar says June 5 and December 5, but the county’s specific 2026 assessment announcement states the 2026 bills are due June 5 and December 7. Save the exact due date printed on the live account or bill.

Land Use Assessment

Farm, forest and open-space parcels need a rollback-tax check before purchase

Loudoun’s Land Use Assessment Program may value qualifying agricultural, horticultural, forest or open-space land according to use rather than full fair-market value. That can reduce current taxes, but deferred taxes may become payable when eligibility ends or land use changes.

Parcel currently qualifies

Review the Land Use Status tab, qualifying use, acreage, renewal history and documentation requirements before assuming the special valuation will continue.

VS
Use changes or parcel transfers

Ask for a rollback-tax estimate before a development, conversion, split or purchase when land-use valuation appears in parcel history.

Application timing

The county requires an application at least 60 days before the tax year for which land-use taxation is sought.

Separate parcel filing

Each parcel requires its own application.

Full renewal

A full renewal is required every six years.

Rollback exposure

Use or ownership changes can create deferred-tax liability.

Fee-date caution: Loudoun’s posted application for the 2026 tax year listed a timely fee of $125 per parcel plus $1 per acre or portion thereof, with a higher late filing charge. That form’s filing period applied to the prior cycle. For a 2027 application, use the current county form and current deadline rather than copying the old date or fee blindly.

Loudoun County assessment and property records FAQs

How do I search Loudoun County property assessment records?

Use the official Loudoun County Real Estate Tax, Assessment & Parcel Database. Search by physical property address, 12-character Parcel ID Number or tax map number, then verify the PIN and physical location before relying on the result.

What software does Loudoun County use for property assessment search?

The official real-property public search is powered by iasWorld Public Access. Loudoun’s separate parcel mapping system is WebLogis.

What is the best way to search a Loudoun property by address?

Enter the street number and main street name first and leave off the street type such as Road, Street or Drive. The official portal recommends omitting the street suffix for better results and supports an asterisk wildcard when spelling is uncertain.

How long is a Loudoun County Parcel ID Number?

The iasWorld search instructions state that Loudoun Parcel ID Numbers are 12 characters long. They can be entered with or without dashes, and the asterisk wildcard can be used for partial PIN searches.

How is Loudoun County real estate assessed?

Virginia real estate is assessed at 100% of fair market value. Loudoun’s Tax Year 2026 assessment represents estimated fair market value as of January 1, 2026.

What is the Loudoun County real-property tax rate for 2026?

The adopted 2026 regular real-property tax rate is $0.805 per $100 of assessed value. Parcels in special tax districts or incorporated towns can have additional taxes, so check the parcel’s Billing District and special-district fields.

When are Loudoun County real-estate taxes due in 2026?

The first-half 2026 real-estate tax was due June 5, 2026. Loudoun’s 2026 assessment announcement states that the second-half bill is due December 7, 2026. The county’s standard calendar uses December 5, so the exact 2026 bill or live Treasurer account should control.

Can I still appeal my 2026 Loudoun property assessment?

The regular administrative-review deadline was March 16, 2026 and the Board of Equalization filing deadline was June 1, 2026. Both have passed. Contact the Commissioner or BOE if you have a special circumstance or need to understand any remaining legal review option.

Where can I find a Loudoun County deed or lien?

Use the Loudoun County Clerk of the Circuit Court land-record system. Occasional users can create a free account for basic index research, while document images cost $0.50 per page plus the applicable transaction convenience fee.

Are Loudoun WebLogis parcel lines legal boundaries?

No. WebLogis is useful for locating parcels, adjoining properties, aerial imagery and map layers, but exact legal boundaries should be verified with recorded plats, deeds and a professional survey.

Information reviewed August 22, 2026: iasWorld Public Access search fields and wildcard behavior, WebLogis tools, 2026 assessment dates, Virginia’s 100% assessment standard, the adopted $0.805 regular real-property rate, 2026 special-district rates, June and December payment dates, assessment-review deadlines, 2026 older-adult/disability relief thresholds, Land Use program guidance, Treasurer payment rules and Clerk land-record access were checked against current Loudoun County official resources.

Verify with the official Ohio source

These calculators use the verified 2026 Ohio Department of Taxation amounts and statutory rules. For your exact bill, exemption status, and county-specific deadlines, always confirm with your county auditor and the Ohio Revised Code:

Ohio Dept. of Taxation — Real Property DTE Forms (105A, 105C, 1, 109) ORC 5715 — Board of Revision ORC 5713 — Taxable Real Property ORC 322.02 — Conveyance Fee ORC 319.54(F)(3) — State Fee ORC 5713.30 — CAUV tax.ohio.gov — Main Portal

Estimates use Ohio's 35% statutory assessment ratio and effective tax rate tiers averaged across major Ohio counties. Your actual bill depends on local school levies, voted millage, inside vs. outside millage splits, House Bill 920 reduction factors (HB 920), and special assessments. The 2026 Homestead general amount ($29,000) and enhanced amount ($58,000) reflect HB 187 inflation indexing — your county auditor's office may show slightly different transitional figures.
