🔒 Official Fairfax County Property Tax Resources
Fairfax County Property Tax Lookup, DTA and iCare Basics
Fairfax County property tax tasks usually involve two official systems: iCare for real estate assessment lookup and DTA for payment, billing, relief, tax rate and appeal support.
The Department of Tax Administration reviews assessed values for real property each year with January 1 as the effective date. Fairfax County states real estate is assessed uniformly and at fair market value.
For a clean workflow, search the property in iCare first, verify the assessment and tax district, then use the DTA real estate payment system to view taxes currently due and pay by e-check or card.
| Need | Best Official Place | What You Can Do |
|---|---|---|
| Pay real estate tax | DTA real estate payment system | View taxes due and pay by e-check, credit card or debit card through the county payment system. |
| Search assessment | Fairfax iCare | Search by address, tax map reference number or map search and review assessed values. |
| Check tax rate | Real estate tax rates page | Review base rate, special districts, service charges and town-related taxes. |
| Appeal assessment | DTA assessment appeals | Discuss with staff appraisers and file appeal with DTA or Board of Equalization if needed. |
| Find relief options | Fairfax tax relief resources | Review relief and exemption programs for eligible homeowners and situations. |
How to Search Fairfax County Property Tax by Address or Tax Map Reference
Fairfax County iCare is the best starting point when you need assessed value, physical characteristics, sales data, tax district or assessment notice details before paying or appealing.
1
Open the official iCare assessment lookup
Search by address, tax map number or map search
Open Fairfax County’s iCare assessment site. It provides assessed values and physical characteristics for residential and commercial properties in Fairfax County.
If address search does not work, try fewer words. Use the street number and main street name first, then narrow the result after you see possible matches.
2
Review assessed value and physical characteristics
This helps explain your tax bill
Check current assessed value, land value, building value, property type, living area, year built, neighborhood, ownership and recent sales where available.
If the record shows wrong square footage, wrong property class, missing damage, incorrect characteristics or unusual sales comparison, save screenshots before contacting DTA.
3
Find your tax district and service charges
Not all tax rates apply to every parcel
Fairfax County says not all rates apply to each parcel. Your assessment notice shows the rates applicable to your property’s tax district.
Check if the parcel is subject to additional charges such as stormwater, leaf collection, refuse, town taxes, Tysons Service District, Reston Service District, McLean Community Center or other special district items.
4
Move to payment after verifying the property
This prevents wrong-parcel payment mistakes
After confirming the parcel, assessment and tax district, open the DTA real estate payment system. Match the parcel and tax year before paying.
How to Pay Fairfax County Real Estate Tax Online
Fairfax County DTA’s real estate payment system lets owners view real estate taxes currently due on county parcels and pay by e-check or credit/debit card using the online payment vendor.
E-check payment
Good for many taxpayers who want bank-account payment. Enter routing and account details carefully before submitting.
Credit or debit card
Convenient, but service fees may apply because DTA uses a third-party processor for card transactions.
1
Start from the official DTA payment page
Avoid unofficial bill-pay sites and sponsored ads
Open the Fairfax County DTA real estate tax payment system. This is the safest starting point for viewing taxes due and choosing an official payment method.
2
Confirm parcel, tax year and installment
Fairfax real estate taxes are generally paid in two installments
Before payment, verify the parcel, owner, address, tax year, amount due, installment and whether prior payments are already posted.
If your mortgage company pays from escrow, check the DTA record before making your own payment to avoid duplicate payment problems.
3
Review service fees before submitting
Card transactions may include third-party fees
Fairfax County says service fees may apply depending on payment method, and DTA uses a third-party processor for credit and debit card transactions.
Read the final payment screen carefully. On a large Fairfax County tax bill, even a small percentage fee can be meaningful.
4
Save receipt and payment proof
Useful for escrow, refinance, sale and dispute records
After payment, save the receipt, confirmation number, amount paid, date, parcel reference and tax year. Recheck the account later to confirm payment posting.

Fairfax County Tax Relief, Exemptions and Homeowner Checks
Fairfax County has tax relief and exemption resources for qualifying homeowners and special situations. Review relief rules early because filing deadlines and documentation can matter.
Older adults
Some older homeowners may qualify for real estate tax relief if county eligibility rules are met.
Disabled residents
Tax relief may be available for qualified permanently and totally disabled individuals.
Other exemptions
Different exemption categories, forms or relief programs may apply depending on property and owner facts.
1
Start from the official tax relief page
Check eligibility before assuming you cannot qualify
Use Fairfax County’s tax relief and exemption resources from the DTA site. Review age, disability, income, asset, residency, ownership and filing requirements where applicable.
2
Prepare documents before filing
Applications may require proof and deadlines
Gather proof of identity, ownership, residency, income, assets, disability status and any prior approval letters. Keep copies of the application and submitted documents.
3
Confirm the benefit appears on the bill
Do not assume approval was applied correctly
After approval, check the next tax bill and payment account. If the relief does not appear as expected, contact DTA quickly with your confirmation and documents.
Fairfax County Real Estate Assessment Appeal Help
If you believe your Fairfax County property is incorrectly assessed, DTA says you can file an appeal with the department or the Board of Equalization. DTA recommends first discussing assessment questions with staff appraisers.
Value disagreement
Use comparable sales, appraisal evidence, market listings and neighborhood assessment comparison.
Property record error
Check living area, property type, condition, year built, land details, improvements and physical characteristics.
Damage or impairment
Fairfax notes appeals may also be filed for properties damaged, destroyed or impaired by violence.
1
Review iCare and assessment notice first
Find the exact issue before contacting DTA
Look up your property in iCare and compare the record with your actual property. Check value changes, physical characteristics, neighborhood sales and tax district details.
Save screenshots and note the exact data point you believe is wrong. A focused appeal is stronger than a general complaint that the tax bill is high.
2
Talk with DTA staff appraisers
Fairfax recommends discussing questions first
Call 703-222-8234, email DTARED@fairfaxcounty.gov or make an appointment. Ask for an explanation of assessment value, comparable sales and property characteristics.
Keep notes with the date, staff name, documents submitted and response. This helps if you move to a formal appeal.
3
File the correct appeal on time
DTA appeal and Board of Equalization routes differ
Use the Fairfax County assessment appeals page for deadlines and application instructions. Fairfax notes appeals can be filed with DTA or the Board of Equalization, depending on the situation.
Real Fairfax County Property Tax Tips That Prevent Costly Mistakes
Fairfax County has high-value properties, local districts, service charges and separate city/town issues. These practical checks help you avoid wrong estimates, missed relief and weak assessment appeals.
Confirm county vs city
City of Fairfax is separate from Fairfax County. If your bill says City of Fairfax, use the city site, not county DTA.
Check tax district number
Fairfax says not all rates apply to every parcel. Your district controls service charges and special rates.
Do not ignore service fees
Card payment fees and special charges can change the final amount. Read the payment screen and bill line items carefully.
Verify escrow posting
If your lender pays, still check DTA payment status before the due date. Escrow mistakes can happen.
Use sales evidence for appeal
Assessment appeals are stronger with comparable sales, property condition proof and data errors, not just frustration.
Save annual assessment PDFs
Keep assessment notice, iCare screenshot, tax bill, receipt and appeal records together by tax year.
