Search Your Fairfax Assessment and Decode the Value

Use Fairfax County’s iCare real-estate assessment system to find a parcel by street address, Tax Map number or map location, then open the record to review the 2026 fair-market value, land and building data, assessment history, neighborhood sales and Tax District.

This guide also solves the questions that usually come next: whether you are searching Fairfax County or the separate City of Fairfax, why a value changed, how the $1.12 base tax rate works, what is still due in 2026, which appeal deadlines have passed, what evidence actually helps, and which office handles assessment, payment, deeds, GIS or tax relief.

Start with quick answer Search assessment Check 2026 dates
Fairfax County and the City of Fairfax are separate taxing jurisdictions. A mailing address that says “Fairfax, VA” does not prove that the property is inside the independent City of Fairfax. County properties use Fairfax County DTA/iCare; City properties use the City of Fairfax Real Estate Assessment Office and a different database, tax rate and appeal calendar.

Quick answer: use Fairfax County iCare for the assessment

For a Fairfax County parcel, open the official Real Estate Assessment Site powered by iasWorld Public Access. Search by address, Map Number or Map Search. Open the matching property, confirm the Tax Map Reference Number and location, then use the record’s Values and Neighborhood Sales information before judging whether the assessment is reasonable.

Why a Fairfax property may not appear where you expect

The address says “Fairfax” It may be inside the independent City of Fairfax rather than Fairfax County.
Exact address returns nothing Simplify the property-location search and retry before adding every directional or suffix.
Condo or unit is confusing Use the Tax Map Reference Number from a notice, tax bill or prior record when available.
New parcel or subdivision Search the map and surrounding parcel records; recent divisions or consolidations can change identifiers.
Recent sale but old owner appears Assessment databases and recorded land documents answer different questions and can update on different schedules.
You only know the owner’s name iCare’s main public search is structured around address, Map Number and Map Search rather than a simple owner-name box.
You need legal ownership proof Move to Circuit Court Land Records; do not rely solely on the assessment owner field.
You need a current tax payoff Move to Revenue Collection/MyFairfax rather than calculating from the assessment page.

Fairfax County assesses real estate at 100% of fair market value

The assessed value is intended to represent market value

Unlike states that apply a fractional assessment ratio after estimating market value, Virginia requires real-estate assessments to represent fair market value. Fairfax County’s annual assessment has a January 1 effective date.

That does not mean the tax rate is 100%. The tax calculation happens afterward by applying the applicable rate per $100 of assessed value.

2026 local market context

The county average is context—not your property’s answer

Fairfax County reported 357,018 taxable parcels for Tax Year 2026, with 316,098 parcels experiencing a value change. Main-book assessments totaled approximately $354.06 billion, up about $12.87 billion or 3.77% from the prior assessment base.

Residential equalization

+3.99% aggregate market-driven change.

Single-family mean

About $1,012,504 in the county’s 2026 published comparison.

Townhome mean

About $612,580 in the 2026 published comparison.

Condominium mean

About $387,560 in the 2026 published comparison.

Do not compare your individual assessment directly to the county average. Fairfax County explicitly warns that aggregate percentages are not necessarily indicative of one parcel. Neighborhood, property type, size, condition, renovations and comparable sales can produce a very different change.

Ask these questions when a value changed

Did land value change?
Did improvement value change?
Was square footage updated?
Was a renovation or addition recognized?
Was a prior data error corrected?
Was there a parcel division or consolidation?
What similar properties sold recently?
Are those sales truly comparable?

2026 tax calculation

The $1.12 base rate may not be the only rate on your parcel

Fairfax County’s Tax Year 2026 rate table lists a general real-estate base rate of $1.12 per $100 of assessed value. A parcel can also fall inside a special tax or service district, so the safest calculation starts with the Tax District number from iCare.

A strong Fairfax appeal attacks the value or the facts—not the tax bill

The normal 2026 appeal windows are closed. The DTA administrative deadline was April 1, 2026 at 4:30 p.m. EDT, and the Board of Equalization deadline was June 1, 2026. The residential online administrative appeal system is no longer accepting 2026 filings.

Fairfax recognizes three core appeal problems

Fair market value The assessment is greater or less than the property’s fair market value based on market evidence.
Lack of uniformity The assessment is out of line with similar properties that should be treated comparably.
Property-description error The record contains a material factual problem involving the physical property.

Evidence that can make the conversation useful

Recent arm’s-length sales
Comparable properties in the assessment neighborhood
Correct living-area measurement
Current photographs of condition
Inspection or repair evidence
Permit or construction-completion information
Evidence of incorrect property characteristics
Income/expense data for applicable commercial property
Appeal-risk detail: a Fairfax assessment review can result in the value being affirmed, decreased or increased. Verify the entire record before asking for review.
Damage after the normal appeal period: if a building has been substantially damaged or destroyed, do not assume the missed April/June appeal dates end every possible value adjustment. Fairfax County provides a separate route for qualifying damaged or destroyed property; contact DTA with the Tax Map number, damage details, photographs, repair estimates and other supporting material.
Appealing does not stop tax payment deadlines. Fairfax County requires taxes to be paid on time even while an appeal is pending; otherwise penalties and interest can apply.
Appraiser discussion script “I am reviewing Tax Map [number] at [address]. The 2026 assessment is [amount]. I believe the issue is [fair-market value / uniformity / property-description error].

2026 tax relief

Fairfax County provides real-estate tax relief for qualifying residents age 65 or older and residents who are permanently and totally disabled, subject to ownership, occupancy, income and financial-worth rules.

First-time or hardship applicant

Relief is capped by the property-value rule

Qualifying senior/disability relief applies to the home and eligible land, with the county’s relief calculation capped at 125% of the mean assessed value of residential properties for the tax year. Value above the applicable relief cap remains taxable.

Other Fairfax exemptions worth checking

Disabled veteran

Fairfax lists real-estate exemption provisions for veterans rated 100% service-connected, permanent and total, subject to the program’s requirements.

Surviving spouse

Separate exemptions exist for certain qualifying surviving spouses of disabled veterans, military members killed in action and first responders killed in the line of duty.

Tax deferral

A separate deferral option may apply to qualifying seniors and people with disabilities with income up to $100,000 and net worth up to $500,000, subject to program rules and interest.

10 practical answers

Fairfax tax assessment search FAQs

Where do I search Fairfax County real-estate assessments?

Use Fairfax County’s official iCare Real Estate Assessment Site. Its main search routes are Search by Address, Search by Map Number and Map Search. Open the matching parcel and verify the Tax Map Reference Number and location before relying on the record.

Can I search Fairfax County property by owner name?

The county’s main public iCare search is structured around property address, Map Number and Map Search rather than a simple owner-name search. If you only have an owner name, use other location clues or contact DTA for help identifying the correct parcel.

Is Fairfax County property assessed at 100% of market value?

Yes. Virginia real property assessments are intended to represent fair market value, and Fairfax County’s annual real-estate assessment uses January 1 as the effective date.

What is the Fairfax County 2026 real-estate tax rate?

Fairfax County’s Tax Year 2026 rate table lists a base real-estate rate of $1.12 per $100 of assessed value. Additional district taxes or service charges can apply, so use the parcel’s Tax District number to determine the correct rate combination.

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

The first installment was due July 28, 2026. The normal second-installment date is December 5, but because December 5 falls on a Saturday in 2026, the county extends the deadline to Monday, December 7, 2026.

What happens if I missed the July 28 Fairfax property-tax payment?

Verify the live balance with Fairfax County Revenue Collection before paying. The county states that a 10% late-payment penalty is applied automatically to late real-estate installments and interest also applies.

Can I still appeal my 2026 Fairfax County assessment?

The ordinary 2026 DTA administrative appeal deadline of April 1 and Board of Equalization deadline of June 1 have passed. If your issue involves substantial property damage or another special circumstance, contact DTA rather than assuming no adjustment route exists.

What evidence helps with a Fairfax assessment challenge?

Useful evidence can include comparable sales, correct measurements, photographs, property-condition documentation, permits and proof of inaccurate property characteristics. A large percentage increase or a high tax bill alone does not establish an incorrect market value.

How do I get my Fairfax County 2026 assessment notice online?

Fairfax County allows linked real property to be accessed through MyFairfax. Linking generally requires the Tax Map Reference Number and the current year’s Web Control Number. The Web Control Number changes each year and appears on the current Notice of Assessment Change.

Is Fairfax City property included in Fairfax County iCare?

No. The independent City of Fairfax maintains its own real-estate assessment database and its own assessment, appeal and tax-payment process. Confirm the actual jurisdiction before using County dates or rates.

Information reviewed August 22, 2026: Fairfax County iCare search routes, iasWorld Public Access portal behavior, 2026 assessment statistics, Virginia fair-market-value assessment basis, Tax Year 2026 rate table, special district examples, July and December payment dates, late-payment rules, administrative and Board of Equalization deadlines, MyFairfax linking requirements, senior/disability tax-relief thresholds, Circuit Court Land Records/CPAN guidance, DTA contacts and the separate City of Fairfax assessment system were checked against current official Fairfax County and City of Fairfax sources.

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.
