Understanding Fairfax VA property tax is essential for homeowners who want to keep more money in their pockets and make informed decisions about their largest asset. Whether you’re a long-time resident or new to Northern Virginia, property taxes can feel like a moving target—and frankly, they often are. The good news? You have more control over your tax bill than you might think.
Fairfax County consistently ranks among the highest-taxed areas in Virginia, which means your property tax bill directly impacts your monthly budget. But before you panic, know this: there are legitimate strategies to reduce what you owe, and understanding how the system works is your first line of defense.

How Fairfax Calculates Property Tax
Your Fairfax VA property tax bill starts with one fundamental equation: assessed value × tax rate = property tax owed. Sounds simple, right? The complexity lies in how the county determines that assessed value.
The Fairfax County Assessor’s office evaluates your property every year based on recent sales of comparable homes in your area. They’re not just eyeballing your place—they use sophisticated computer-assisted mass appraisal (CAMA) systems that analyze square footage, lot size, condition, location, and market trends. This means your assessment can shift significantly year to year, especially in a hot real estate market like Northern Virginia.
Unlike some states, Virginia uses what’s called “fair market value” assessment, meaning they estimate what your home would sell for on the open market. This is why your assessed value often creeps higher during seller’s markets and why you need to stay vigilant about challenging inflated assessments.
Current Tax Rates and Assessments
As of 2024, Fairfax County’s property tax rate sits at approximately $0.82 per $100 of assessed value for residential properties. While that might seem modest, it compounds quickly on homes valued at $500,000 or more—which describes a significant portion of Fairfax County real estate.
For example, a home assessed at $600,000 would generate roughly $4,920 in annual property taxes at the current rate. That’s $410 per month just for property taxes alone, before factoring in homeowners insurance or HOA fees.
The county reassesses properties annually, and these assessments typically increase 3-5% per year in appreciating markets. If you haven’t challenged an assessment in the past three years, you may be leaving money on the table. The county’s own data shows that 20-30% of assessment appeals result in reductions, meaning many homeowners successfully lower their bills when they take action.
Assessment Appeals Process
Here’s where you can actually fight back against rising property taxes. Fairfax County gives homeowners a narrow window—typically 30 days from when you receive your assessment notice—to file a formal appeal.
The appeal process involves three potential steps:
Step 1: Informal Review – Contact the Assessor’s office and request an informal review. Bring evidence like recent appraisals, repair estimates for needed work, or comparable sales data showing lower values. Many disagreements get resolved here without formal proceedings.
Step 2: Board of Equalization – If the informal review doesn’t satisfy you, file an appeal with the Board of Equalization. You’ll present your case before a panel that reviews assessment disputes. Bring documentation: photographs of defects, inspection reports, or a professional appraisal showing lower value.
Step 3: Circuit Court Appeal – This is your nuclear option, reserved for significant disputes. It’s more expensive and time-consuming, but available if you believe the Board got it wrong.
Most homeowners find success at the informal review stage. Bring comparable sales from the past 6-12 months showing homes with similar characteristics selling for less than your assessed value. The Assessor’s office has access to this same data, and if you’ve found legitimate comps, they may adjust your assessment without requiring a full appeal.
Homestead Exemptions and Credits
Virginia’s homestead property tax exemption offers a tax break for primary residences, but it’s not automatic—you must apply. The exemption reduces your taxable assessed value by up to $25,000 (as of 2024), which translates to roughly $205 in annual tax savings at Fairfax’s current rate.
While $205 might not sound transformative, it’s free money if you qualify and haven’t claimed it. The application is straightforward and available through the Fairfax County Assessor’s website. You’ll need to prove you own the property and it’s your primary residence.
Additionally, if you own property jointly with a spouse, you may qualify for a married couple’s exemption that stacks on top of the basic homestead exemption. Some homeowners don’t realize they’re eligible for these combined benefits, so review the county’s eligibility requirements carefully.
Senior Relief Programs Available
If you’re 65 or older and meet income requirements, Fairfax County offers the Elderly and Disabled Real Property Tax Relief Program. This program can freeze your property tax assessment at its current level or reduce it if you meet specific criteria.
The income limits are modest—around $58,000 for a single filer and $70,000 for joint filers as of recent years—but if you qualify, the benefit is substantial. Your assessment stays locked in place, protecting you from annual increases even as your home appreciates. For someone on a fixed income, this can be the difference between staying in your home or being forced to sell due to rising taxes.
There’s also a Disabled Veteran exemption that works similarly for qualifying veterans. If you or a family member served and has a service-connected disability rated at 100% by the VA, you may be eligible for a substantial reduction in assessed value.
Agricultural Use Tax Reductions
If you own property in Fairfax County that qualifies as agricultural land—typically 5+ acres used for farming, orchards, or similar purposes—you can apply for agricultural use assessment instead of residential assessment. This dramatically reduces your tax burden because agricultural land is assessed at use value, not market value.
A 10-acre parcel that might be assessed at $1 million for residential purposes could be assessed at $20,000-$30,000 under agricultural use classification. That’s the difference between $8,200 and $200-$250 in annual taxes.
The catch? You must actively use the land for agricultural purposes and maintain that use. The county monitors compliance, and if you stop farming or sell to a developer, you’ll owe back taxes plus interest. Still, if you genuinely operate agricultural land, this program is worth exploring immediately.
Tax Payment Options and Deadlines
Fairfax County property taxes are due in two installments: December 5 and June 5. If you miss these deadlines, penalties and interest accrue quickly—currently 10% penalty plus 6% annual interest. That’s expensive money you’re paying to the county, not toward your actual tax obligation.
You have several payment options:
Online Payment: Pay through the county’s website using a credit/debit card (small processing fee applies) or bank account transfer (free).
Automatic Withdrawal: Set up automatic payment on your due dates—the easiest way to avoid late fees.
Check or Money Order: Mail to the county treasurer’s office by the due date.
In-Person: Pay at the Fairfax County Government Center during business hours.
Many homeowners set up automatic payments and forget about them, which is fine—until your assessment increases dramatically and your payment doesn’t cover the new amount. Review your bill each year and adjust your payment if needed. Also, if you have a mortgage, your lender likely collects property taxes through escrow, which simplifies the process but means you should verify the amount collected matches your actual bill.
Common Mistakes to Avoid
Mistake #1: Ignoring Assessment Notices – Many homeowners receive their assessment notice and assume it’s gospel. Wrong. The county makes mistakes, and you have the right to challenge them. At minimum, compare your assessment to recent sales of similar homes in your neighborhood.
Mistake #2: Missing the Appeal Deadline – You typically have 30 days to appeal. Miss that window, and you’re stuck for another year. Mark your calendar the moment you receive the notice.
Mistake #3: Not Applying for Available Exemptions – The homestead exemption and senior programs don’t apply automatically. You must file the paperwork. Hundreds of eligible homeowners leave money on the table simply because they didn’t know to apply.
Mistake #4: Underestimating Property Condition Impact – If your home has deferred maintenance, roof issues, or outdated systems, document these problems. The Assessor’s office is supposed to account for condition, but they don’t always get it right. Professional inspection reports carry weight in appeals.
Mistake #5: Comparing Your Assessment to Neighbor’s Prices – Your neighbor might have bought their house in 2015 for $400,000; yours might be assessed at $650,000 today. That’s not necessarily wrong—it reflects current market value. Use comparable sales from the past year, not purchase prices from years ago.

Frequently Asked Questions
What’s the difference between assessed value and market value?
Assessed value is what the county estimates your home is worth for tax purposes. Market value is what someone would actually pay for it. They’re often close but not identical. Market value can fluctuate based on buyer demand and specific transactions; assessed value is calculated using formulas applied to comparable sales. If your home sits on the market unsold for months, its market value might be lower than its assessed value, which could support an appeal.
Can I appeal my assessment every year?
Yes. You can file an appeal annually if you believe your assessment is incorrect. Many homeowners appeal only once or twice, but technically you can do it every year. However, expect diminishing returns if your home’s condition and market comparables haven’t changed significantly.
How do I find comparable sales for my appeal?
The Fairfax County Assessor’s website provides public assessment data. Real estate websites like Zillow, Redfin, and MLS records show recent sales. Focus on homes sold in the past 6-12 months within your neighborhood with similar square footage, lot size, and condition. The county will have the same data, so if your comps are solid, they’re harder to dismiss.
Are property taxes deductible on my federal tax return?
Yes, up to $10,000 per year in state and local taxes (SALT), which includes property taxes. This deduction is available if you itemize deductions rather than taking the standard deduction. For most homeowners in Fairfax County, property taxes alone often exceed $10,000, meaning you can’t deduct the full amount. Consult a tax professional to determine whether itemizing makes sense for your situation.
What happens if I don’t pay my property taxes?
The county will assess penalties and interest, eventually placing a lien on your property. After an extended period of non-payment, the county can foreclose and sell your home to recover the debt. This is serious—don’t ignore bills. If you’re struggling to pay, contact the Fairfax County Treasurer’s office about payment plans or hardship options.
Does Fairfax County offer property tax deferral programs?
Fairfax County does offer limited deferral options for seniors and disabled individuals who meet income and property value thresholds. The Elderly and Disabled Real Property Tax Relief Program can defer taxes, though this creates a lien on the property that’s paid when the home is sold. It’s a useful tool for those facing cash flow challenges.
Final Thoughts on Fairfax VA Property Tax
Your Fairfax VA property tax bill doesn’t have to be a fixed expense. By understanding how assessments work, knowing your appeal rights, and taking advantage of available exemptions and credits, you can reduce your tax burden legitimately and substantially.
The key is taking action. Don’t assume the county got your assessment right. Don’t overlook exemptions because you didn’t know they existed. Don’t miss appeal deadlines because you thought it was too complicated.
Start by reviewing your most recent assessment notice. If it seems high compared to recent sales of similar homes, file an appeal. If you’re 65 or own agricultural land, apply for relief programs. If you haven’t claimed the homestead exemption, do it today.
Property taxes are one of the largest expenses homeowners face, but they’re also one of the few expenses where you have direct recourse. Take that power seriously, and your wallet will thank you.
