Fairfax County Property Tax Guide: Pay, Search, Due Dates & Exemptions
Fairfax County property tax is easiest to handle when you verify the real estate record before paying. A missing bill, old stub number, mortgage escrow payment, City of Fairfax mix-up, assessment change, or tax relief question can send you to the wrong place. This guide explains how to search your property, understand the bill, check due dates, pay safely, review exemptions, and handle appeals before you use an official Fairfax County page for the final action.
Quick Answer
For Fairfax County real estate property tax, start with the official Real Estate Assessment site. Search by property address, tax map reference number, or map search, confirm the property, review assessment and tax details, find the current year’s stub number if needed, then pay through Fairfax County Department of Tax Administration payment options. Real estate taxes are paid in two installments, generally due July 28 and December 5; when a due date falls on a weekend or holiday, use the county’s official deadline page before paying.
Fairfax County vs City of Fairfax: Use the Correct Tax Office
This is one of the most important checks. Fairfax County, Virginia and the City of Fairfax are separate local governments with separate tax systems. A property with a Fairfax mailing address is not always taxed by the City of Fairfax, and a City of Fairfax tax page should not be used for Fairfax County real estate unless the property is actually inside the independent city.
| Question | Fairfax County Property | City of Fairfax Property |
|---|---|---|
| Which official site should I use? | Fairfax County Department of Tax Administration and iCare assessment search. | City of Fairfax Treasurer/Commissioner or city tax pages. |
| How do I verify? | Search the Fairfax County assessment site by address or tax map reference number. | Use City of Fairfax property/tax resources only if the parcel is inside the city jurisdiction. |
| Why it matters | Payment, bill lookup, tax relief and appeals must match the correct jurisdiction. | Paying or researching on the wrong site can delay the correct action. |
Practical rule: Do not choose a tax office based only on the word “Fairfax” in the address. Use the parcel record and official jurisdiction to confirm.

Before You Pay: Fairfax County Real Estate Tax Checklist
Most payment problems happen when a taxpayer pays before confirming the record. Use these checks before entering bank/card details, mailing a check, or assuming a mortgage company has paid.
How to Search Fairfax County Property Tax Records
The official Fairfax County Real Estate Assessment site is the safest starting point for real estate property tax research. It allows users to search by property address, tax map reference number, or map search. Use it to confirm the parcel before paying, appealing, checking tax relief, or discussing a bill with DTA.
- Open Fairfax County’s Real Estate Assessment search.
- Select address search, tax map reference number search, or map search.
- Enter the simplest version of the property address if a full address does not work.
- Confirm the parcel, property location and tax map reference number.
- Review assessment, values, tax details, sales, property characteristics and related record tabs where available.
| Search Method | Best Use | Risk to Avoid |
|---|---|---|
| Address search | Best for homeowners who know the property address but not the tax map number. | Selecting the wrong unit, similar street name, or nearby parcel. |
| Tax map reference number | Best when using a bill, assessment notice, closing papers, appeal record or MyFairfax setup. | Typing the number incorrectly or using an old document for a different property. |
| Map search | Best when the address is uncertain, land is vacant, or you are checking parcel boundaries. | Assuming the map result is correct without verifying the property details. |
What If You Did Not Receive a Fairfax County Real Estate Tax Bill?
Do not wait for a paper bill if the deadline is approaching. Fairfax County says failure to receive a bill does not exempt a taxpayer from making sure taxes are paid by the due date. You can view tax information online or request help from the Department of Tax Administration.
- Search the assessment site for your property.
- Check the current year information and bill/payment details.
- If you need a bill copy or cannot locate the information, contact Fairfax County DTA.
- Do not wait until the due date to ask for a replacement bill.
- Save the bill copy and payment proof after paying.
Practical tip: If you moved, bought the property recently, changed mailing address, or rely on escrow, verify tax information online instead of waiting for mail.
How to Pay Fairfax County Real Estate Property Tax
Fairfax County offers several payment paths, including online payment, MyFairfax, mail, phone, in-person service and other payment options. Real estate online payment may require this year’s stub number from the tax bill or Real Estate Assessment site, so search first if your bill is missing.
- Confirm the property and jurisdiction.
- Find the current year’s stub number if online payment asks for it.
- Choose the correct bill year and installment.
- Review payment amount, fee notice, bank/card details and confirmation screen.
- Save the confirmation number or receipt.
| Payment Option | Best For | Micro Steps | Official Link |

| In-person payment | Complex questions, missing bill issues, payment proof problems or accessibility needs. | Bring bill/property details → confirm accepted methods → pay or ask question → save receipt. | Hours & Directions |
Escrow warning: If your mortgage company pays real estate taxes, confirm the county payment status before paying personally. Duplicate payments can create refund delays and extra paperwork.
Fairfax County Property Tax Due Dates
Fairfax County real estate taxes are paid annually in two installments. The normal due dates are July 28 for the first installment and December 5 for the second installment. When the due date falls on a weekend or holiday, the official county due-date page controls the adjusted deadline.
- Open Fairfax County’s tax due dates and deadlines page.
- Find the Real Estate Tax section.
- Confirm whether you need the first installment or second installment.
- Check for weekend or holiday adjustment.
- If the date has passed, check payment status before paying again.
| Real Estate Tax Event | Typical / 2026 Timing | What It Means |
|---|---|---|
| Assessment notice mailed | End of February. | Review assessed value and property characteristics early. |
| DTA administrative assessment appeal deadline | April 1, 2026 by 4:30 p.m. EDT for online/email appeals or postmark if mailed. | Use this if you want DTA review of the assessment. |
| Tax rate set | Early May. | The Board of Supervisors sets the rate used to calculate the tax bill. |
| Board of Equalization appeal deadline | June 1. | Separate appeal route; confirm current year rules. |
| First installment payment due | July 28. | Pay the first half by the official deadline. |

Fairfax County Real Estate Tax Rate and How the Bill Is Calculated
Fairfax County real estate tax is based on assessed value and the tax rate set by the Board of Supervisors. For 2026, the county lists the real estate base rate as $1.12 per $100 of assessed value. Some properties may also have additional district, town, service, transportation, stormwater, refuse, leaf collection or other charges depending on where the property is located.
- Find the property’s assessed value on the assessment site or assessment notice.
- Review the current real estate tax rate.
- Check whether special district rates, town taxes, stormwater or service fees apply.
- Compare current assessment with the prior year to explain bill changes.
- If property facts or value look wrong, review appeal options.
DTA uses real property data to assess real property at estimated fair market value as of January 1 each year.
The Board of Supervisors sets the rate, and the tax rate is applied to assessed value to determine the amount due.
Some properties may have additional rates or fees based on transportation districts, stormwater, towns, service districts or local services.
If your assessment increased, your bill can rise even if the rate changes only slightly or stays close to the prior year.
Why Did My Fairfax County Property Tax Bill Change?
A higher bill can come from several sources. Do not assume the payment office made a mistake until you compare the assessment, tax rate, district charges, tax relief, property classification and escrow status.
| Possible Cause | Where to Check | What To Do |
|---|---|---|
| Assessment increased | Assessment notice and iCare property values. | Review property characteristics and comparable sales; appeal by the deadline if needed. |
| Tax rate changed | Real Estate Tax Rates page. | Compare current and prior year rates per $100 of assessed value. |
| Special district or fee applies | Tax rate/fee table and property tax district information. | Check transportation, stormwater, town, refuse or service district charges. |
| Tax relief changed | Tax relief/exemption approval and renewal records. | Review senior, disability, deferral, disabled veteran or surviving spouse relief. |
| Escrow or payment timing | Mortgage statement and Fairfax County payment information. | Confirm whether lender payment posted before paying yourself. |
Fairfax County Property Tax Relief and Exemptions
Fairfax County offers real estate tax relief and exemption programs for qualifying taxpayers. These programs are not the same as simply disputing assessed value. Relief may depend on age, disability status, income, assets, veteran status, surviving spouse status, occupancy, principal residence and application requirements.
- Identify which program may apply: senior, disability, deferral, disabled veteran, surviving spouse or another exemption.
- Read the eligibility requirements before assuming you qualify.
- Gather age, disability, income, asset, veteran, surviving spouse, occupancy and ownership documents as applicable.
- Submit the correct application or contact DTA for account-specific guidance.
- Keep approval letters and renewal documents with your tax records.
| Program | Who Should Review | Important Detail | Official Link |
|---|---|---|---|
| Senior tax relief | Property owners age 65 or older. | Eligibility can depend on age, occupancy, income, assets and application rules. | Senior & Disabled Relief |
| People with disabilities | Owners who are permanently and totally disabled. | The county’s relief page explains qualifications and documentation requirements. | Senior & Disabled Relief |
| Real estate tax deferral | Eligible seniors or permanently and totally disabled applicants who need deferral instead of immediate relief. | Deferral is different from exemption; review repayment and qualification details. | Tax Deferral Details |
| Disabled veteran exemption | Veterans rated 100% service-connected, permanent and total disability who occupy the property as principal residence. | Official page also covers certain surviving spouse scenarios. | Disabled Veteran Exemption |
| Other exemptions | Users looking for broader county tax relief, exemption or special-category guidance. | Programs vary by property type, owner status and legal requirements. | Other Tax Relief & Exemptions |
Do not confuse assessment appeal with tax relief: An appeal challenges the value or property data. Tax relief/exemption programs reduce or defer tax based on eligibility.
Fairfax County Real Estate Assessment Appeals
If you believe the assessed value or property data is wrong, review the assessment appeal process quickly. Appeal deadlines are separate from payment deadlines. Paying the tax bill does not necessarily mean you agree with the value, and appealing the value does not automatically remove the need to pay on time.
- Open your assessment notice or iCare property record.
- Check assessed value, property characteristics, land/building details and comparable sales.
- Review the administrative appeal deadline for DTA.
- Review Board of Equalization timing if you need that route.
- Keep copies of evidence, photos, sales data, correction requests and confirmation receipts.
| Appeal Topic | What It Means | Practical Reminder |
|---|---|---|
| DTA administrative appeal | A review through the Department of Tax Administration. | For 2026, the DTA administrative appeal deadline shown was April 1, 2026 by 4:30 p.m. for online/email appeals. |
| Board of Equalization | A separate appeal route from DTA administrative review. | Check the official due-date/deadline page for current BOE timing. |
| Payment deadline | Tax payment due date is separate from assessment appeal deadline. | Confirm whether payment is still required while an appeal is pending. |
If Your Mortgage Company Pays Fairfax County Property Tax
Escrow does not mean the tax is already paid. Your mortgage company may collect monthly escrow, but the county payment still needs to post by the installment due date. Always compare the county record with your mortgage statement.
- Search the property record and confirm the correct parcel.
- Check the current year, installment and due date.
- Compare your escrow statement to the county payment information.
- If payment is not posted near the due date, contact your mortgage servicer for proof.
- Do not pay personally until you know whether the lender payment is pending or already sent.
If You Recently Bought a Fairfax County Property
New buyers often see property tax confusion because the bill may relate to a prior owner or prior tax period, closing credits may not mean the county was paid, and the mortgage escrow account may not be fully synced with county payment records yet.
- Find the tax map reference number or property address from closing documents.
- Search the official assessment record.
- Compare the tax bill with your closing statement and escrow disclosure.
- Check whether your mortgage servicer is responsible for the next installment.
- Review mailing address and contact details for future notices.
- Check whether tax relief, exemption or deferral from a prior owner still affects expectations.
Closing credit warning: A seller credit at closing is not the same as a posted county tax payment. Always confirm payment status on the official record.
Late, Delinquent or Unpaid Fairfax County Property Taxes
If you missed an installment, confirm the balance before making another payment. Late taxes can involve penalty, interest, collection actions, account-specific notices and additional steps. Do not rely only on an old bill if the due date has passed.
- Search the property and confirm the current unpaid amount.
- Verify which installment is late.
- Check whether escrow payment posted late or not at all.
- Contact DTA if the balance, bill, stub number or payment history is unclear.
- Keep proof of any payment and follow-up communication.
Common Fairfax County Property Tax Mistakes to Avoid
These mistakes create delays, duplicate payments and wrong-office confusion. Review them before searching, paying or calling.
Fairfax County and City of Fairfax are separate. Confirm jurisdiction before paying or appealing.
Online real estate tax payment may require the current year’s stub number. Find it from the bill or assessment site.

Assessment appeal deadlines come before payment due dates. Review value concerns early after notices are mailed.
Senior, disability, disabled veteran and other relief programs have eligibility and application rules.
Failure to receive a bill does not remove the obligation to pay on time. Search or contact DTA.
