Ahhh September and October, your calendar is suddenly full of fall festivals, college football games, back to school nights, and a reminder to pay your personal property (car) tax before the Wednesday, Oct. 5 deadline.

To give you more time for the fun things on the calendar, here are five things you need to know about car taxes (and as a bonus, here’s how to report possible car tax evaders):

#4: Registration Fee

Your personal property tax bill includes a local registration fee for vehicles regularly garaged, stored or parked in Fairfax County.

  • This is separate and distinct from the state registration fee paid to the Virginia DMV.
  • Other than a safety inspection sticker, Fairfax County does not require the display of a physical windshield decal.

New this year, the Town of Clifton and the Town of Herndon have both likewise eliminated the requirement to display a local registration windshield decal. Due to state law, each town will continue to charge a local registration fee, but there is no longer a physical decal. Fairfax County personal property tax bills now include the local registration fee charged by those towns. Fairfax County, the Town of Clifton and the Town of Herndon have entered into an agreement so the county will now bill and collect the current registration fee on behalf of the towns, and will forward the fees to each town as appropriate. The town fee will now be prorated upon the sale or move of the vehicle.

Residents of the Town of Vienna must still pay town registration fees directly to Vienna. Fairfax County is not billing Vienna town fees at this time.


#5: Tax Relief

You may qualify for tax relief, if you are a senior at least 65 years old, or permanently and totally disabled, a disabled veteran, or a spouse of a veteran killed in action. More information and forms are online, or call 703-222-8234 (TTY 711).
