Search Fairfax County Property Tax

Fairfax County property tax records sit in a single online portal run by the Department of Tax Administration. The official starting point is the DTA website at https://www.fairfaxcounty.gov/taxes/. From there, residents reach the property search tool through the iCare portal.

The search system works through Fairfax iCare, which accepts multiple lookup methods. Users can enter a street address, type a parcel map number, or use an owner name. Each option pulls current assessment data, tax bill history, and payment status for the selected property.

The step-by-step search process looks like this:

1. Open the iCare property search portal at https://icare.fairfaxcounty.gov/ffxcare/search/commonsearch.aspx?mode=address.
2. Select a search mode from address or map number.
3. Type the requested details into the search bar.
4. Click the search button to load the property record.
5. Review assessment values, tax district code, and land use classification.
6. Check the bill status to see if any balance remains unpaid.
7. Note any active appeals or exemptions applied to the parcel.

Each record card displays the tax year, assessed value, bill amount, and payment deadlines. Users can print a copy for their own records or save it as a PDF. For deeper land records, residents can consult the Circuit Court Land Records system for deed history and ownership transfers.

Fairfax County Real Estate Tax Rates and Structure

Fairfax County sets one real estate tax rate each fiscal year through the Board of Supervisors. The FY 2026 rate stands at $1.1225 per $100 of assessed value. The proposed FY 2027 budget would retain this same rate. This rate applies to every residential and commercial parcel across the county.

The tax base for each property equals 100% of its fair market value as of January 1 of each year. The county assessor updates those values annually. For tax year 2026, residential assessments rose an average of 4.31% from the prior year, marking one of the largest jumps in recent memory.

Tax bills combine the base real estate rate with several service charges. Refuse collection, leaf collection, and stormwater fees appear as line items on each bill. The table below shows the core rate structure used for billing purposes.

Property owners in special tax districts may pay additional levies. The table covers the standard county-wide rate. Special service districts layer extra charges on top of the base figure. Refer to the official DTA website for current installment due dates.

How Assessed Value Differs from Market Value

The assessor uses mass appraisal models calibrated to recent sales. Each neighborhood receives annual updates based on closed transactions. Homes in hot markets see steeper assessment jumps than homes in slower zones.

Owners can review the assessment methodology on the DTA website. The site breaks down land value, improvement value, and total value for each parcel. Buyers and sellers can use the same data to estimate future tax exposure before closing.

Property Assessment Process in Fairfax County

The Department of Tax Administration mails real estate assessment notices each February. For tax year 2026, notices were mailed on February 17. These notices show the new assessed value, any changes from the prior year, and the deadline for filing an appeal.

Property owners have a limited window to challenge the assessment. The appeal deadline is printed on the assessment notice. Missing the window means waiting another full year to dispute the value. Appeals may be made through the Department of Tax Administration or the Board of Equalization.

The assessment process includes several steps:

• Data collection from sales, building permits, and aerial imagery
• Computer-assisted mass appraisal modeling
• Review of anomalies by trained assessors
• Notice mailing with new values
• Open appeal period for owner objections
• Finalization of the tax roll for billing

Each parcel card on the iCare portal lists the effective date of the last assessment. Owners can compare year-over-year values to spot large jumps that might justify an appeal.

Fairfax County Property Tax Calculator Methods

Two practical calculator methods exist for Fairfax County property tax. The first uses the official assessment data from iCare. The second applies the published tax rate to a known market value.

The iCare method is the most accurate. Pull the assessed value from the property record, then multiply by $1.1225 per $100. For example, a home with an assessed value of $700,100 pays roughly $7,861 in base real estate tax before service charges.

The manual method works for buyers who want to estimate future taxes on a pending purchase. Take the expected assessed value, divide by 100, and multiply by 1.1225. The result gives the base tax bill before refuse and stormwater fees.

Key inputs for any Fairfax tax estimate include:

• Most recent assessed value from iCare
• Property tax district code
• Refuse collection service area
• Stormwater service fee classification
• Active exemptions or tax relief credits

Properties with homestead exemption receive a separate calculation. Senior owners and disabled residents may qualify for additional relief that lowers the final bill.

Payment Methods for Fairfax Property Tax

Fairfax County accepts property tax payments through multiple channels. Each method has its own processing time and fee structure. Picking the right method helps avoid late penalties.

The DTA online portal accepts electronic checks and credit cards. Phone payments route through an automated system staffed weekdays from 8 a.m. to 4:30 p.m. Drop boxes sit outside the Government Center for after-hours deposits. Mail payments go to the DTA lockbox. In-person payments happen at the Government Center counter.

Card payments carry a convenience fee from the processor. E-checks and paper checks avoid that fee. Late payments post on the day received, so mail delays can trigger penalties even when postmarked on time.

Fairfax County Property Tax Bill Due Dates

Fairfax County splits the annual real estate tax bill into two installments. The first installment covers the period from January through June. The second installment covers July through December.

Each installment has its own due date. Missing the first deadline triggers penalties on that half of the bill. The second deadline carries the same risk for the second half. Refer to the DTA website for the current year’s installment due dates.

Common due dates for Fairfax County property tax include:

• First installment: refer to the DTA website for the current due date
• Second installment: refer to the DTA website for the current due date
• Personal property (car) tax: October 5, often extended to early November
• Business tangible personal property: refer to DTA for current filing deadline

The Board of Supervisors sometimes extends deadlines during weather events or system outages. Recent extensions pushed the personal property tax deadline from October 6 to November 5. Owners should check the DTA site for any active extensions before mailing a payment.

Delinquency Penalties and Late Fees

Late payments on Fairfax County property tax trigger penalties and interest on the unpaid balance. Owners should consult the DTA directly for the current penalty and interest rate structure.

For personal property tax, the rate may include an additional DMV registration hold. Owners who cannot pay on time should contact the DTA at (703) 222-8234. The office sometimes approves installment plans for owners facing financial hardship. A written request with supporting documents speeds up the review.

Common penalty structures on Fairfax County tax bills include:

• Interest charged on unpaid real estate tax (rate set by the DTA)
• Penalty assessed on personal property tax after the due date
• Additional penalty if unpaid 30 days after due date
• DMV registration stop for vehicles with unpaid car tax
• Lien filing for properties with multi-year delinquency

Call the DTA at (703) 222-8234 to discuss hardship options or confirm the current penalty schedule.

Property Tax Exemptions in Fairfax County

Fairfax County offers several exemptions that lower the taxable value of a property. Some exemptions apply only to real estate. Others extend to personal property and business tangible assets. Each program has its own eligibility rules and application form.

The most common exemption is the homestead exemption, which caps annual assessment increases for owner-occupied homes. Other programs target veterans, disabled residents, surviving spouses, and religious organizations.

Common Fairfax County property tax exemptions include:

• Homestead exemption for primary residence owners
• Disabled veteran exemption with full or partial relief
• Surviving spouse of a fallen service member exemption
• Religious use exemption for places of worship
• Nonprofit and charitable use exemption
• Elderly or disabled tax relief credit

Exemptions must be renewed or re-verified in some cases. The veteran exemption, for example, often requires annual proof of disability rating. The elderly relief program uses a one-time application with periodic income checks.

Homestead Exemption Details

The homestead exemption caps annual assessment increases for owner-occupied homes. The cap applies only to the principal residence. Rental properties and second homes do not qualify.

Owners must file the homestead application with the DTA. The form asks for proof of residency, ownership, and primary residence status. Approved applicants see the cap reflected on the next assessment notice.

Tax Relief Programs for Seniors and Disabled Residents

Fairfax County runs a separate tax relief program for residents age 65 and older, and for permanently disabled residents of any age. The program uses a sliding scale based on household income and net worth. Lower-income applicants receive larger relief credits.

Applicants must meet baseline conditions including owning and occupying the property, being a Fairfax County resident, and falling under the income and net worth limits set each year. Refer to the DTA for the current year limits.

Eligibility rules for the senior and disabled relief program include:

• Age 65 or older, or 100% disabled rating
• Property owned and occupied as primary residence
• Household income below the published ceiling
• Net worth below the published ceiling excluding primary home
• Annual re-application in some cases

The DTA mails workshop notices each spring for the upcoming filing season. Workshops help residents complete the application without errors. The official workshops page at https://www.fairfaxcounty.gov/taxes/workshops lists upcoming dates and required documents. The DTA is open weekdays from 8 a.m. to 4:30 p.m. on the phones and to walk-in traffic.

Fairfax County Property Tax Appeal Process

Property owners who disagree with the assessed value can file an appeal. The appeal goes first to the Department of Tax Administration. If denied, the case moves to the Board of Equalization for a formal hearing.

Appeals must be filed by the deadline printed on the assessment notice. Late appeals get rejected without review.

The step-by-step appeal process looks like this:

1. Review the assessment notice and gather comparable sales data
2. File the appeal online or by mail before the deadline
3. Wait for the DTA administrative review
4. Receive a decision or hearing notice
5. Attend the Board of Equalization hearing if needed
6. Receive a written ruling with adjustment details

Owners with strong evidence of value overstatement often see reductions. The best evidence includes recent sales of similar homes in the same neighborhood. A licensed appraiser can also prepare a formal valuation report for the hearing.

Property Tax Refund Process

Overpayments on Fairfax County property tax trigger automatic refunds in most cases. The DTA issues refunds for duplicate payments, exemption credits applied after billing, and successful appeal adjustments. Refunds process within 30 days of verification.

Owners who receive an unexpected refund should confirm the source. Appeals can produce refunds months after the original payment. Exemption approvals also generate retroactive credits.

Common sources of Fairfax County property tax refunds include:

• Successful assessment appeal adjustments
• Approved exemption or relief credit
• Duplicate payment by check and online
• Overpayment due to billing error
• Escrow account surplus refunds from mortgage lenders

Refunds under a small threshold stay on the account as a credit. Larger refunds issue as paper checks mailed to the owner of record. The DTA updates the property record once the refund clears.

Personal Property Tax on Vehicles

Fairfax County levies an annual personal property tax on vehicles registered in the county. The tax rate applies to the vehicle’s assessed value, which the county calculates from a published guidebook. Most cars, trucks, motorcycles, and trailers fall under this program.

Vehicle owners receive a bill each fall. The standard deadline falls in October. Recent years saw the deadline extended to early November to give owners more time. The Board of Supervisors sets the extension based on billing cycle conditions.

Key facts about Fairfax personal property tax include:

• Annual bill sent to the registered owner in fall
• Assessed value based on published trade-in value
• Tax rate set per $100 of assessed value
• October deadline with possible November extension
• DMV registration stop for unpaid bills

Vehicle owners who move out of the county or sell the car can file for a partial-year proration. The DTA prorates the bill based on the date the vehicle left the county. A copy of the out-of-state registration or bill of sale supports the request.

Business Property Tax Requirements

Businesses in Fairfax County file an annual Business Property Return. The return covers furniture, fixtures, machinery, equipment, and tools used in the business. The county uses the return to assess business tangible personal property tax each year.

Returns must be filed by the deadline set by the DTA. Late filers face an automatic assessment based on prior year data. That assessment may be higher than the actual value, leading to a larger tax bill. Refer to the DTA for the current year’s filing deadline.

Key elements of the Fairfax County business property tax include:

• Annual Business Property Return (refer to DTA for current due date)
• Tax rate applied to reported asset value
• Original cost basis used for depreciation
• Late filing penalty applied to estimated assessment
• Separate filing for leased and owned equipment

Businesses can file the return through the DTA portal. New businesses must register with the DTA after starting operations in the county. Refer to the DTA for the registration window and current procedures.

Fairfax County Tax Forms and Documents

The DTA hosts a library of official tax forms on the county website. Each form has its own PDF and instructions. Forms cover real estate appeals, exemption applications, business returns, and refund requests.

Common forms on the Fairfax County DTA site include:

• Real Estate Assessment Appeal Form
• Homestead Exemption Application
• Disabled Veteran Exemption Application
• Senior and Disabled Tax Relief Application
• Business Personal Property Return
• Personal Property Tax Relief Application
• Address Change Request Form

The library research page at https://research.fairfaxcounty.gov/tax/forms also helps residents access printable tax forms. The page lists federal and state tax resources, plus a few county-specific documents. The library system charges a small printing fee for paper copies.

Property Tax Liens and Sale Information

Unpaid Fairfax County property tax becomes a lien on the real estate. The lien takes priority over most other claims. The county can eventually sell the property at a tax sale to recover the unpaid balance.

The DTA publishes a tax sale list each year. The list includes delinquent parcels that have crossed the legal threshold for sale action. Bidders compete at the public auction, and the winning bid pays off the tax debt plus fees.

Key facts about the Fairfax County tax lien process include:

• Lien attaches on the due date of the unpaid bill
• Notice sent to the owner before sale action
• Publication in a local newspaper of record
• Auction held at the Government Center
• Right of redemption for the former owner in some cases

Owners facing a tax sale can stop the process by paying the full balance plus penalties and fees. Payment plans sometimes work for owners who catch the issue early. Calling the DTA at (703) 222-8234 starts the resolution process.

GIS Map and Parcel Lookup Tools

Fairfax County runs a GIS map that overlays property data on an aerial view. The map shows parcel boundaries, owner names, land use codes, and assessment values. Users can search by address or parcel number.

The map helps buyers evaluate a property before closing. Investors use it to spot zoning changes and development patterns. Researchers use it to track neighborhood trends over time.

Common features on the Fairfax County GIS map include:

• Parcel boundary lines and dimensions
• Owner name and mailing address
• Land use code and zoning designation
• Assessed land and improvement values
• Tax district boundaries
• School district and voting precinct overlays

The iCare portal at https://icare.fairfaxcounty.gov/ffxcare/search/commonsearch.aspx?mode=address provides the public access point. Users can toggle between map, address, and parcel number searches from a single page.

Renter Property Tax Considerations

Renters in Fairfax County do not pay property tax directly. Landlords pay the tax as part of owning the rental property. The landlord may pass some of that cost through to tenants in the form of rent, but the tax bill itself stays in the landlord’s name.

Renters who want to research their landlord’s tax status can search the property by address on the iCare portal. The portal shows the current bill status, last payment date, and any active liens. This data helps renters spot landlords with serious delinquency issues.

Key points for renters in Fairfax County include:

• Property tax billed to the owner of record
• Rent may include a property tax pass-through
• Public records show owner tax status
• Escrow accounts do not apply to tenants
• Renters cannot appeal the assessment directly

Some apartment complexes advertise gross rent that includes a property tax estimate. Renters comparing units should ask how the landlord accounts for annual tax changes. A jump in the property tax bill can push rents higher the next lease cycle.

HOA Fees and Property Tax Distinctions

Homeowners association fees and property tax bills are separate charges. HOAs collect dues to maintain common areas, pay insurance, and fund community amenities. The county collects property tax to fund schools, roads, and public services.

Some HOA communities sit in special tax districts. Those districts add a small annual charge on top of the base tax rate. The charge shows up as a line item on the tax bill rather than on the HOA statement.

Common differences between HOA fees and property tax include:

• Property tax goes to county and state budgets
• HOA fees stay within the community
• Tax bills are public record
• HOA ledgers stay private to the community
• Tax bills qualify for federal and state deduction in some cases
• HOA fees do not qualify as tax deductions

Buyers evaluating a home in an HOA community should request both the current tax bill and the latest HOA budget. The combined monthly cost gives a clearer picture of the total housing expense.

Land Tax Rates for Undeveloped Property

Undeveloped land in Fairfax County pays the same real estate tax rate as improved property. The current rate sits at $1.1225 per $100 of assessed value. The assessment depends on the land’s zoning, acreage, and highest and best use.

Landowners who hold raw acreage for future development see tax bills based on the underlying value. Agricultural land with an active farming use may qualify for a separate land use assessment that lowers the bill. Owners must apply for the land use classification each year.

Key facts about Fairfax County land tax include:

• Standard rate of $1.1225 per $100 of assessed value
• Land use assessment available for qualifying agricultural parcels
• Special classifications available for qualifying parcels (refer to DTA for details)
• Annual application required for all special classifications

Buyers of vacant land should request the current year’s tax bill before closing. The bill shows the assessment, the rate, and any pending land use application. Land within sewer service areas may also carry an additional availability charge.

Real Estate Tax History and Records Access

Fairfax County keeps real estate tax records going back many years. The Circuit Court Land Records system holds deed transfers, mortgages, and liens. The DTA system holds tax payment history and assessment rolls.

Title companies, attorneys, and homeowners often need historical tax data. The data confirms chain of ownership, checks for unpaid liens, and validates prior assessments. Each record can be printed or downloaded for use in legal filings.

Common sources for Fairfax County real estate tax history include:

• DTA iCare portal for current and recent tax years
• Circuit Court Land Records site for deed and lien history
• Fairfax County Public Library for archived research
• Title company abstract reports for chain of title
• County archive vault for older paper records

Consult the official Fairfax County website for current URLs to the Circuit Court land records system and related services.

Fairfax County Tax Statistics and Market Context

Fairfax County property tax bills run higher than the statewide and national medians. Recent data shows a median annual tax payment of $7,669 in the county. That figure is more than double the Virginia statewide median of $2,872 and well above the national average. Other recent data points to a median tax bill of $7,795 in 2026.

Home values drive the gap. The median home sale price in early 2026 reached $700,100, with 2,225 properties changing hands in the first quarter. Higher assessments produce higher tax bills even when the rate stays flat.

Key Fairfax County property tax statistics include:

• Median home sale price of $700,100 in Q1 2026
• Median annual tax bill of $7,669 per parcel (2026 data)
• Median tax bill of $7,795 in 2026 (alternate data source)
• Average assessment increase of 4.31% for 2026
• Effective tax rate of 1.1% of median assessed value

The effective rate exceeds the national average of 0.888% reported in 2026 data. Homeowners in Idylwood, Woodburn, and Fair Lakes carry some of the highest effective tax rates in the county. The gap comes from a combination of higher assessments and flat tax rates.

Electronic Filing and Online Services

Fairfax County encourages electronic filing for most tax services. The DTA portal supports online appeals, exemption applications, business property returns, and address changes. Electronic filings process faster than paper submissions.

Online services cut down on printing costs, mailing delays, and data entry errors. The portal guides users through each form with built-in validation. Errors get flagged before submission rather than after processing.

Common online services on the Fairfax County DTA portal include:

• Real estate appeal submission
• Homestead exemption application
• Business personal property return filing
• Address change request
• Tax bill payment
• Filing of personal property tax relief

Owners who prefer paper filings can still mail forms to the DTA. The mailing address appears on every form and on the DTA website. Paper filings take longer to process because staff must enter the data manually.

Tax Year vs Fiscal Year in Fairfax County

Fairfax County real estate tax uses a calendar tax year. The tax year runs from January 1 through December 31. Each tax year produces one annual bill split into two installments.

The fiscal year differs from the tax year. The fiscal year starts on July 1 and runs through June 30. The Board of Supervisors adopts the budget for each fiscal year in the spring before the fiscal year begins.

Common tax year and fiscal year milestones include:

• January 1: assessment date for the new tax year
• February: assessment notices mailed
• April: appeal filing deadline (per the assessment notice)
• July 1: new fiscal year begins
• First installment due in July (refer to DTA for current date)
• Second installment due in December (refer to DTA for current date)

Owners who see a tax bill in the spring should know that the bill covers the current calendar tax year. The bill sent in fall covers the second half of the same tax year. Two bills per year equal one tax year of liability.

Submit the form by mail or in person to the DTA office at 12000 Government Center Parkway, Suite 223. Approved exemptions reduce the taxable value on the next bill.

What penalties apply if my Fairfax property tax payment is late?

Paying before the due date avoids all penalties and keeps your credit clear.
