Nobody Warns You About the Virginia Car Tax

Nobody Warns You About the Virginia Car Tax

Updated September 2026

 You move from Maryland to Northern Virginia. You find the house, you sign the lease or close the deal, you get the keys. Six months later a bill shows up from the county for your car. Not the state — the county. And it’s four figures.

Nobody warns you about this. So I will.

The short answer

Virginia counties charge an annual personal property tax on every vehicle garaged in the county. Maryland does not. Maryland collects a one-time excise tax when you title the car and then leaves you alone. Virginia bills you every single year, for as long as you own it.

That’s the whole difference, and it’s the thing people miss when they compare a Fairfax payment to a Bowie payment.

The two deadlines that get people fined

Here’s the part that actually costs money, because it’s two separate clocks and most people only know about one.

Clock one: the DMV. Under Va. Code § 46.2-662 you have 30 days from establishing residency to title and register your vehicle in Virginia. Keep running Maryland tags past that and Virginia can hit you with a $100-per-year “No Plate Tax” plus a $250 “No Plate Penalty.”

Clock two: the county. Separately — and this is the one nobody tells you — you have 60 days to file a personal property return with the county you live in. Fairfax County charges a 10% late-filing penalty with a $10 minimum if you miss it. Registering with the DMV does not file your county return for you.

Two agencies. Two deadlines. Two penalties.

What it actually costs

The rate is per $100 of assessed value, and every county sets its own. Two examples I can source directly:

Run a $35,000 assessed SUV through that and you get roughly $1,151.64 in Fairfax and $828.12 in Loudoun for the year. Same vehicle. A county line apart.

A note on Loudoun: the county already has a rate cut to $2.94 scheduled for 2027, so date-stamp any number you see, including mine.

I’m deliberately not publishing relief percentages for Arlington, Alexandria, Prince William or Fairfax City. Arlington and Alexandria use tiered relief that doesn’t reduce to a single number, and quoting a flat percentage for them would be wrong. Call the county.

How they decide what your car is worth

This is where people argue and lose. Virginia localities assess using the January 1 J.D. Power “Clean Loan” value — not the trade-in value, not what you paid, not what the dealer offered you. Clean Loan runs higher than trade-in, which is why the assessment usually looks high to you.

The tax is prorated monthly, so a car you bring in mid-year is billed for the months it was garaged there. Due date in Fairfax is October 5, 2026. Loudoun bills twice, May 5 and October 5.

The Maryland comparison

Maryland has no annual vehicle property tax. It does have a one-time excise tax, and it went up: HB 352 in the 2025 session raised the excise rate from 6.0% to 6.5% and doubled the title fee from $100 to

$200, both effective July 1, 2025.

So Maryland front-loads the cost, Virginia spreads it out forever. On a car you keep eight years, Virginia is usually the more expensive side of the river. On a car you flip every two years, it’s closer than you’d think.

What to do about it

Budget for it before you sign anything. If you’re comparing a house in Woodbridge to a house in Waldorf, the mortgage payment is not the whole comparison — add roughly a thousand dollars a year per vehicle on the Virginia side and see if the answer changes.

File your county return inside 60 days even if you think you registered everything. And if you have a teenager with a car, that’s a second bill.

I’ll tell you straight: this catches more DMV relocations than any other line item, and it catches them a year after they’ve already committed to the house.

Rates and fees cited are the published Fairfax and Loudoun County figures current as of September 2026 and change annually. Confirm your own county’s rate, relief percentage and filing deadline directly with the Commissioner of the Revenue before relying on any number here.
