NOTES
Fairfax County is Virginia’s most populous jurisdiction and one of the largest, most service-rich county governments accessible anywhere in the country – its library system alone (23 branches, nearly 3 million items) rivals many entire state systems, and its permitting process is correspondingly divided across many specialized county divisions rather than a single office. Because the independent City of Fairfax sits inside the county’s boundaries but is legally separate, always confirm whether your address falls within county or city jurisdiction before contacting an office – a permit or service issued by one does not apply within the other. All contact information above was sourced from official county pages as of this writing; phone numbers and hours should be reconfirmed directly with the relevant office before a visit.
About Fairfax County
Fairfax County is the most populous jurisdiction in Virginia and the thirty-ninth most populous county in the United States, covering 407 square miles of Northern Virginia between the Potomac River and the Bull Run Mountains. It is home to more than 1.15 million residents and generates an economy that, if it were a state, would rank among the largest in the country. The county’s proximity to Washington, DC – anchored by federal agencies, defense contractors, technology companies, and intelligence community infrastructure – has made it one of the wealthiest large jurisdictions in the United States by median household income.
Tysons – the unincorporated urban center at the intersection of Routes 7 and 123 – has undergone one of the most ambitious suburban-to-urban transformations in American history. Once a sprawling edge city of surface parking and enclosed malls, Tysons has attracted billions in high-rise residential and commercial development since the Silver Line Metro opened in 2014. Tysons Corner Center and Tysons Galleria remain among the highest-grossing retail centers on the East Coast, while new residential towers and mixed-use developments are adding thousands of units annually.
McLean is the county’s most exclusive residential community, home to a disproportionate share of senior federal officials, intelligence community leadership, diplomats, and technology executives. The Central Intelligence Agency headquarters sits within McLean’s boundaries at Langley. Median household incomes and property values in McLean consistently rank among the highest in the country.
Reston – planned by Robert E. Simon (whose initials give it its name) and developed beginning in 1964 – was one of America’s first planned communities and remains a model for mixed-use, walkable suburban development. The arrival of the Silver Line Metro’s second phase transformed Reston Town Center into a genuine transit-oriented center. Reston also anchors Fairfax County’s technology cluster, with major office presence from government contractors, cybersecurity firms, and cloud computing companies.
Springfield and Burke are the county’s major middle-class residential communities in the southern tier, defined by their access to the Beltway (I-495), Fort Belvoir, and the Pentagon, and by school districts that consistently rank among Virginia’s strongest.
Great Falls is Fairfax County’s affluent western edge – large-lot estate properties, equestrian land, and the Great Falls Park where the Potomac River drops 76 feet through a series of dramatic rapids, one of the most spectacular natural features in the mid-Atlantic.
Amazon HQ2 – located across the county line in Arlington – has had significant spillover effects on Fairfax County’s residential market, particularly in Tysons, Reston, and communities along the Silver Line corridor.

Fairfax County conducts annual reassessments of all real property at 100% of estimated fair market value as of January 1 each year. Assessment notices are mailed in February. The county’s Department of Tax Administration (DTA) at 12000 Government Center Parkway, Fairfax, VA 22035, phone 703-222-8234, administers assessments and tax collection.
The appeal process – two levels:
Level 1 – Informal review: Contact the DTA directly by April 1 to request an informal review. Provide comparable sales data, an independent appraisal, or other market evidence. Many successful appeals are resolved at this level without a formal hearing.
Level 2 – Board of Equalization: If the informal review does not resolve the dispute, appeal to the Fairfax County Board of Equalization by June 1. The Board is an independent body that conducts formal hearings. If still unsatisfied, further appeal is to the Circuit Court.
Key assessment considerations for Fairfax County:
– The Northern Virginia market’s volatility means year-over-year assessment changes of 5–10% are not unusual in rising markets.
– New construction triggers immediate reassessment upon completion of the improvement.
– The county offers a real estate tax relief program for qualifying seniors and permanently disabled residents – income and net worth limits apply. Apply at the DTA.
Virginia taxation context: Virginia has no state estate tax and no state inheritance tax – a significant advantage over Maryland (estate tax above $5M) and DC (estate tax above $4M) for wealthy Northern Virginia residents. Virginia does impose a probate tax of $1 per $1,000 of estate value ($0.3333 per $1,000 for the state, $0.6667 per $1,000 local) on estates going through probate.
OWNWELL CTA: Fairfax County annual reassessments at 100% fair market value – informal review deadline April 1, Board of Equalization deadline June 1. Northern Virginia’s sustained appreciation creates regular appeal opportunities. Ownwell manages the appeal with no upfront cost.

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
Fairfax Circuit Court, Probate Division 4110 Chain Bridge Road, Suite 401, Fairfax, VA 22030 (703) 691-7320 (press 3, 5, 1 for probate appointments)
Fairfax County is Virginia’s most populous jurisdiction, part of the 19th Judicial Circuit, and shares its Circuit Court with the independent City of Fairfax. Virginia has NO separate probate court – probate (“qualification”) is handled entirely by the Circuit Court Clerk’s Office in the city or county where the decedent resided.
Step 1: figure out which path applies
Virginia calls the probate process “qualification” rather than “appointment,” and – unusually among states – it happens administratively at the Circuit Court Clerk’s Office, not before a judge, unless a dispute arises.
Small Estate Affidavit (Va. Code § 64.2-601, the “Virginia Small Estate Act”) – available when the decedent’s entire personal probate estate (excluding real estate) does not exceed $75,000, at least 60 days have passed since death, and no personal representative has been appointed or has a pending application in any jurisdiction. If a will exists, it must first be admitted to probate (recorded with the Clerk) even though no executor is appointed – this is a simpler recording step, not full administration. As of July 1, 2026, the affidavit must be filed on the statewide form (CC-1685) prepared by the Office of the Executive Secretary of the Supreme Court of Virginia.
Single Small Asset Release (Va. Code § 64.2-602) – an even simpler mechanism: any person or institution holding a single asset of $35,000 or less may release it directly to a successor once 60 days have passed since death and no personal representative has qualified, without any affidavit being required at all.
Real Estate Affidavit (Form CC-1612) – if the decedent owned only real estate, this affidavit can be recorded directly in land records without a full probate proceeding. Real estate generally CANNOT be transferred through the small estate affidavit process above.
Full Qualification / Administration – the standard path for larger or more complex estates. The personal representative appears before the Clerk (or deputy clerk), takes an oath, files the will and death certificate, and typically posts a surety bond (unless waived by the will or by all beneficiaries). The estate is then supervised by a Commissioner of Accounts – an attorney appointed by the Circuit Court to review inventories, accountings, and creditor claims – throughout administration.
Step 2: filing for administration
The person seeking to qualify as executor or administrator brings the original will (if any) and a certified death certificate to the Fairfax Circuit Court Probate Division – an appointment is strongly recommended.
The Clerk reviews the will’s validity (often via a self-proving affidavit attached to the will, or witness testimony) and admits it to probate.
The personal representative takes an oath and qualifies, posting a bond if required; the Clerk issues Letters Testamentary or Letters of Administration.
The Commissioner of Accounts oversees the estate going forward – reviewing the inventory, receipts and disbursements, and periodic accountings filed by the personal representative.
The personal representative notifies creditors, pays valid debts, and manages estate assets.
Remaining assets are distributed to beneficiaries or heirs, and the estate is closed once final accounting is approved.
What it costs
Virginia imposes a PROBATE TAX on most wills admitted to probate and grants of administration: $1 state tax + $0.33 local tax for every $1,000 of estate value (roughly $1.33 per $1,000, or about $133 on a $100,000 estate). No tax is imposed on estates valued at $15,000 or less. This tax applies to real and tangible personal property located in Virginia, and – for resident decedents – to intangible personal property (bank accounts, stocks, bonds) regardless of location.
Filing fees for qualification vary by estate size and are set by the Clerk’s Office; confirm current Fairfax County fees directly.
Virginia does NOT impose a state estate tax or inheritance tax – Virginia repealed its estate tax for deaths on or after July 1, 2007. Only the federal estate tax may apply, and only to very large estates (roughly $15 million exemption for 2026).
