Fairfax County provides online payment options for most tax bills. Before paying, identify your tax type first: real estate tax, vehicle tax, business tax, dog license, parking ticket, BPOL, transient occupancy tax, or another county fee.

For real estate tax, Fairfax County says you need this year’s stub number from the real estate tax bill, and if you do not have the current bill, you can find the stub number through the real estate assessment site or call DTA for help.

Fairfax County Vehicle Tax or Car Tax Payment Help
Fairfax County vehicle tax is one of the most common “tax collector” searches. Most vehicle or car tax bills are mailed in the summer and are due by October 5, unless the vehicle was bought or moved into the county on or after July 1.
For vehicles purchased or moved into Fairfax County on or after July 1, Fairfax County says bills are mailed in January of the following year and payment is due by February 15. If a payment date falls on a Saturday, Sunday or county holiday, the due date is the following business day.

Payment method router

Fairfax County Tax Relief, Exemptions and Senior Help
If you are a senior, disabled resident, veteran, surviving spouse, low-income homeowner or family helper, do not only look at the payment page. Fairfax County has separate tax relief and exemption resources that may apply before or after a tax bill is issued.
Tax relief is not the same as making a payment. Eligibility, income limits, ownership rules, filing deadlines, vehicle status, real estate status and documentation can matter. If you already applied but your bill does not reflect relief, call the proper DTA or tax relief contact route before assuming the bill cannot be corrected.
Official source: Fairfax County tax relief and exemptions and DTA contact page.Before paying full amount
Check whether you have an active or pending relief application, exemption, veteran benefit or senior-related filing.
Before missing a deadline
Ask Fairfax County what must be paid while an application, correction or appeal is pending. Do not assume relief automatically pauses payment.
Keep documents together
Save notices, application dates, confirmation emails, letters, proof of income, proof of ownership and call notes.
