Search the Parcel, Verify the 2026 Value, and Finish the Tax Task

Use Loudoun County’s real property database to find a parcel by street address, Parcel Identification Number (PIN), Tax Map Number or combined search, then review ownership, assessment history, land and improvement values, sales, building characteristics, tax districts and parcel history.

This guide goes beyond finding a record. It explains the county’s iasWorld portal quirks, Virginia’s 100% fair-market-value assessment rule, the $0.805 2026 county real estate tax rate, June and December tax dates, neighborhood sales, WebLogis mapping, deed research, split-parcel warnings, assessment appeals, tax relief and land-use deferral risks.

Start with quick answer Search the parcel Check 2026 tax dates
Critical Loudoun parcel warning: the county’s own assessment portal warns purchasers to investigate parcels that were divided or combined within the last 36 months to make sure all taxes and levies are paid. Also review parcel history for past Land Use Assessment because deferred taxes may become relevant after a change in use or ownership circumstances.

Quick answer: use the Commissioner parcel database first

Loudoun County’s public real estate system is powered by iasWorld Public Access. Start with Property Address, PIN or Tax Map Number, open the correct parcel, verify the address and PIN, then save the Profile, assessment values, sales and district information before moving to the Treasurer, WebLogis or Clerk of the Circuit Court.

1 Find the parcel Address, PIN or Tax Map Number.
2 Verify the record Match address, PIN and owner information.
3 Read the assessment Land, improvements, total value and districts.

Portal software quirks

Loudoun uses iasWorld Public Access—and it has a few important behaviors

Portal quirks that prevent wasted searches
Portal behavior
What it means
Best user action
Search choices are separated
Address, PIN, Tax Map and advanced/combined searches are separate paths.
Use one strong identifier first instead of over-filtering.
System maintenance can occur
The portal may temporarily display a maintenance/unavailable message.
Do not interpret downtime as a missing property; retry later or call 703-777-0260.
Parcel history matters
A current parcel can have earlier split, combination or land-use history.
Open parcel history before a purchase or rollback-tax decision.
Neighborhood Sales is inside the record
Comparable sales are available after opening the parcel.
Use the Neighborhood Sales link on the right side of the property record.
WebLogis and assessment pages are linked
A parcel PIN can move between GIS and assessment records.
Keep the PIN copied so you can verify both systems describe the same parcel.
Buyer micro-check: if a parcel was divided or combined in the previous 36 months, do not review only the current parcel screen. The county expressly warns purchasers to investigate whether all taxes and levies on the parcel history have been paid.
Assessment office call script “I am researching PIN [number] at [address]. I need help with [record correction / parcel history / split or combination / valuation / land-use history]. Can you confirm which current parcel record and prior parcel history I should review?”

Virginia uses 100% of fair market value—not a 35% assessment ratio

2026 regular county rate: $0.805 per $100

Loudoun real estate is assessed at 100% of fair market value. For tax year 2026, the regular county real property tax rate is $0.805 per $100 of assessed value.

A parcel assessed at $800,000 produces a base county calculation of approximately $6,440 before considering applicable town taxes, special tax districts, exemptions, credits or other parcel-specific adjustments.

2026 tax calendar

First-half taxes are past due; second-half taxes are due December 7

2026 first half June 5, 2026

The regular first-half due date has passed.

2026 second half December 7, 2026

2026 assessment announcement lists December 7 for the second installment.

Why December 7? Weekend shift

The normal calendar date is December 5; December 5, 2026 falls on Saturday.

Assessment notice ≠ tax bill. The February assessment notice shows the January 1 value. The Treasurer sends the actual tax bills. A value appeal does not automatically postpone the tax due date.

If the June 5 payment was missed

Copy the property PIN or tax account information Have the correct parcel ready before checking the bill.
Check whether a mortgage servicer paid it Escrowed property may already show a posted payment.
Verify the current balance with the Treasurer Do not simply send the original installment amount after the deadline.
Ask about penalty and interest Late payments may accrue charges after the due date.
Confirm any town or special-district charges The bill may contain more than the regular county rate.
Save payment confirmation Keep the PIN/account, date, amount and receipt together.

Comparable-sales research

Use Neighborhood Sales before assuming the assessment is too high

Loudoun says 2026 assessments reflect market activity occurring during 2025. The parcel database provides a Neighborhood Sales link on the right side after you open a property record.

Match physical features
  • Living area
  • Age
  • Style
  • Quality
  • Condition
Match location
  • Neighborhood
  • Lot size
  • Road / access
  • School and market area
  • Town / district context
Match transaction quality
  • Valid market sale
  • Relevant sale period
  • Similar use
  • No unusual conditions
  • Comparable improvements
Do not compare only price per square foot. Loudoun’s assessment review considers proximity and features such as age, living area, acreage and amenities. A nearby sale can still be a weak comparable when those characteristics differ materially.
Recorded land records

The assessment record is not the deed record

Loudoun County Clerk of the Circuit Court maintains land records from 1757 to the present. In 2025, the Clerk launched an occasional-user remote access option that makes basic indexing information available online at no charge.

Property-characteristic errors still deserve prompt review.

Do not confuse a factual record correction with a formal appeal. If the parcel shows an incorrect living area, condition or another property characteristic, Loudoun directs owners to contact the assessment office and may schedule an inspection.

Land Use Assessment can lower current taxes—but creates deferred-tax exposure

Loudoun’s Land Use Assessment Program taxes qualifying land according to qualifying agricultural, horticultural, forestal or open-space use. The difference between use value and fair market value is generally deferred while the land remains eligible.

$125 Application fee per parcel
+$1 Per acre or portion thereof
Nov. 1 Regular annual filing date published by the program
$300 Additional late fee per parcel
Dec. 5 Published final late-filing date
Current filing tip: the program page states a regular November 1 filing deadline and late filing through December 5. If you are filing for the next assessment year, confirm the year-specific calendar with Land Use staff rather than assuming a weekend date is automatically extended.

What a new application can require

Separate application for each parcel
All real estate taxes current
Correct qualifying use category
Forest Management Plan for forestry when required
Leasing Farmer / Tenant statement when applicable
Agricultural or horticultural production documentation
Schedule F / Form 4835 or other qualifying business records where appropriate
Fee for each parcel and qualifying acreage

Rollback tax risk

Do not buy land-use property without reviewing the parcel history. Loudoun warns that land previously receiving use-value deferral may be subject to deferred taxes. A qualifying-use change can trigger rollback taxes.
Report a use change Loudoun’s rollback-tax form states that a change to non-qualifying use must be reported to the Commissioner within 60 days.
Lookback period Rollback calculation can involve the current year plus the previous five tax years.
Estimate ≠ invoice A rollback-tax estimate is not the amount due and should not be used as a payment invoice.

10 practical answers

Loudoun County tax assessment FAQs

How do I search Loudoun County real estate assessments?

Use Loudoun County’s iasWorld Public Access real property database. The portal offers Property Address, Parcel ID Number (PIN), Tax Map Number, Advanced Searches and Combined Search. Start with one strong identifier and verify the PIN and address after opening the parcel.

Can I search Loudoun County property by owner name?

The main public portal prominently provides address, PIN, Tax Map and advanced/combined search paths. If you are researching ownership, first identify the parcel using the strongest available property identifier and then review the owner information shown on the parcel record. For legal title, use the Clerk’s land records.

What percentage of market value is real estate assessed at in Loudoun County?

Virginia real estate is assessed at 100% of fair market value. Loudoun’s annual assessment represents the county’s estimated market value as of January 1 of the assessment year.

What is the Loudoun County real estate tax rate for 2026?

The regular 2026 Loudoun County real property tax rate is $0.805 per $100 of assessed value. Special tax districts or incorporated-town taxes may create additional charges for some parcels.

When are Loudoun County real estate taxes due in 2026?

The first-half 2026 real estate tax installment was due June 5, 2026. Loudoun’s 2026 assessment announcement lists the second-half bill as due December 7, 2026 because the normal December 5 date falls on a Saturday.

Why can a recently split Loudoun parcel be risky to research?

The county’s own property-search portal warns that parcels divided or combined within the last 36 months should be investigated to ensure all taxes and levies are paid. Review both current and prior parcel history before relying on the new parcel alone.

How do I find comparable sales for a Loudoun assessment?

Open the subject parcel in the assessment database and use the Neighborhood Sales link on the right side of the property record. Compare location, age, living area, acreage, amenities, quality and condition rather than relying only on sale price.

How do I appeal a 2026 Loudoun County assessment?

The 2026 administrative review deadline was March 16 and the Board of Equalization filing deadline was June 1. Those county-level deadlines have passed. If the property record contains a factual error, contact the Real Estate Division promptly and ask about the appropriate correction or remaining legal review options.

Where do I find Loudoun County deeds and land records?

The Clerk of the Circuit Court maintains land records from 1757 to the present. Occasional users can create a free remote account for basic index information and purchase document images for $0.50 per page plus the published transaction convenience fee.

How does Loudoun County Land Use Assessment affect taxes?

Qualifying agricultural, horticultural, forestal or open-space land may be assessed using use value, deferring part of the real estate tax while eligibility continues. A later change to a non-qualifying use can trigger rollback taxes, so buyers should review the parcel’s land-use history.

Information reviewed August 25, 2026: Loudoun County’s iasWorld property-search portal, 2026 assessment notice guidance, 100% fair-market-value assessment standard, adopted $0.805 real property rate, 2026 tax dates, special district rates, appeal deadlines, WebLogis search instructions, property-record fields, public assessment reports, 2026 older/disabled tax relief requirements, Land Use Assessment rules, rollback-tax guidance and Clerk land-record access were checked against current Loudoun County sources.

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.
