If you own property in Fairfax County, Virginia, you’re probably aware that your real estate tax bill shows up like clockwork—and it’s rarely a pleasant surprise. The truth? Fairfax County real estate tax assessment is one of the highest in the nation, and most homeowners have no idea they might be overpaying. We’re talking about thousands of dollars over the life of your mortgage that could stay in your pocket with the right strategy.
Here’s the real talk: property taxes in Fairfax County aren’t just a line item on your mortgage statement. They’re a living, breathing expense that changes year to year, and the county’s assessment process is designed in a way that many homeowners don’t fully understand. But that’s exactly why you’re here. This guide cuts through the noise and gives you actionable steps to understand, challenge, and potentially reduce your Fairfax County real estate tax assessment in 2024.
How Fairfax County Real Estate Tax Assessment Works
Let’s start with the basics, because understanding the system is half the battle. Fairfax County conducts a countywide reassessment every four years. The county assessor’s office estimates the fair market value of your property, and that valuation becomes the basis for your annual tax bill.
Here’s how the math works: Your property’s assessed value × the tax rate = your annual real estate tax bill. Sounds simple, right? But the assessed value is where things get murky. The county uses a mass appraisal system that compares your home to similar properties that have sold recently. If you haven’t updated your property record with the assessor—or if the county made mistakes about your home’s condition—you could be paying taxes on an inflated value.
The last comprehensive reassessment in Fairfax County happened in 2020, with adjustments in 2022 and 2024. This means your home’s assessed value may not reflect actual market conditions, especially if your neighborhood has experienced significant changes or if your property has defects the county didn’t catch.
Think of it like this: the county is making educated guesses about your home’s value based on data they collected months or even years ago. Sometimes those guesses are spot-on. Sometimes they’re wildly off. And unlike most other things in life, you have the right to push back.
Pro Tip: The county sends assessment notices annually, usually in December. Mark your calendar. You have only 30 days from the date of the notice to file a formal appeal. Miss that window, and you’re stuck with that assessment for another year.
Current Tax Rates & What You’re Actually Paying
For 2024, Fairfax County’s real estate tax rate is $0.82 per $100 of assessed value. On the surface, that might not sound like much. But let’s put it in perspective: if your home is assessed at $600,000 (which is close to the median home value in parts of Fairfax County), you’re paying $4,920 per year in real estate taxes alone. That’s $410 per month, every month, just for the privilege of owning your home.
And here’s what most people don’t realize: Fairfax County real estate tax assessment rates have been climbing steadily. Over the past five years, property values have surged, and while the tax rate itself hasn’t changed dramatically, the amount you pay has increased significantly because your assessed value went up.
To get your specific tax bill, multiply your home’s assessed value by 0.0082. You can find your assessed value on the Fairfax County tax assessor’s website, or look at your annual tax bill. The bill breaks down exactly what you’re paying in county taxes, school taxes (which is a separate line item), and any special district assessments.

How to Challenge Your Assessment (And Win)
This is where things get empowering. You absolutely have the right to challenge your Fairfax County real estate tax assessment, and thousands of homeowners do it every year. The key is knowing exactly how to do it.
First, gather evidence. Here’s what you need:
- Your official assessment notice (sent by the county)
- Recent appraisals (if you’ve had your home appraised for a mortgage or refinance)
- Documentation of any property defects or needed repairs
- Sales data for comparable homes in your neighborhood
- Photos showing condition issues (foundation problems, roof damage, outdated systems)
- Any previous assessment appeals or adjustments
The county’s assessment is based on the assumption that your home is in average condition. If your roof is shot, your HVAC system is ancient, or you have foundation issues, those factors should reduce your assessed value. The county assessor doesn’t physically inspect every home, so if they missed something significant, that’s your leverage.
According to the Virginia Department of Tax, homeowners have the right to appeal assessments through the Board of Equalization. This is your formal avenue, and it’s free to use.
To file an appeal, you’ll submit a formal request to the Fairfax County Board of Equalization within 30 days of receiving your assessment notice. The board will review your evidence and either uphold the assessment, adjust it, or in rare cases, significantly reduce it. The process typically takes 60-90 days.
Pro move: if you’re appealing, include a professional appraisal if you can get one. Yes, it costs money upfront (usually $300-500), but if it results in a lower assessment, you’ll recoup that cost in one or two years of reduced taxes.
Exemptions, Credits & Tax Relief Programs
Fairfax County offers several programs designed to reduce your real estate tax burden, and most homeowners have no idea they exist. Let’s break them down.
Homestead Exemption: If your primary residence is in Fairfax County, you may qualify for a homestead exemption that reduces your assessed value by up to $25,000. That’s a potential tax savings of $205 per year right there. You have to apply, and it’s not automatic.
Senior Citizens Property Tax Relief: If you’re 65 or older and meet income requirements, you might qualify for significant tax relief. Fairfax County has a program that can freeze your property tax at a lower level or provide outright reductions.
Disabled Veterans Exemption: Veterans with service-connected disabilities rated by the VA can receive property tax exemptions. The amount depends on your disability rating.
Agricultural/Open Space Exemptions: If you own land in Fairfax County that qualifies as agricultural or open space, you can get substantial reductions. This is often overlooked by rural property owners.
To understand whether you qualify for any of these programs, visit the Fairfax County Tax Assessor’s office website or call their office directly. They’re surprisingly helpful, and there’s no penalty for asking questions.

The Appeal Process: Step-by-Step
Let’s walk through the actual mechanics of appealing your assessment. This isn’t complicated, but it does require attention to detail and timing.
Step 1: Receive Your Assessment Notice – Usually arrives in December. Check the date immediately. You have 30 days from that date.
Step 2: Review the Assessment Details – Compare the assessed value to your recent appraisal or mortgage documents. Look for errors in property description (square footage, lot size, number of bedrooms, etc.). The county makes mistakes more often than you’d think.
Step 3: Gather Your Evidence – Compile appraisals, comparable sales, and documentation of any defects. If you’re claiming the property is in worse condition than the county thinks, get photos and contractor estimates.
Step 4: File Your Appeal – Submit a formal appeal request to the Board of Equalization. You can do this online, by mail, or in person. Include all your evidence and a clear explanation of why you believe the assessment is too high.
Step 5: Attend the Hearing – If the board requests a hearing, you’ll present your case. You can do this yourself or hire a representative. Many homeowners handle it themselves and do just fine.
Step 6: Receive the Decision – The board will issue a decision, typically within 90 days. If you disagree, you have the right to appeal further to circuit court, though this is rare.
Warning: Don’t miss the 30-day filing deadline. Once it passes, you’re locked into that assessment for another year. Mark it on your calendar the moment you receive the notice.
If you want to understand how tax abatements work, that’s another avenue for relief in some situations, though it’s more commonly used for commercial properties or new development incentives.
Smart Moves to Reduce Your Tax Burden
Beyond challenging your assessment, there are other legitimate strategies to lower your Fairfax County real estate tax burden.
Make Energy-Efficient Improvements: Some energy-efficient upgrades (solar panels, high-efficiency HVAC systems) may qualify for tax credits or exemptions. Check with the county about what qualifies.
Document Property Defects: If you haven’t already, photograph and document any issues with your home. A leaky roof, outdated electrical system, or foundation crack all reduce your property’s value in the eyes of an appraiser—and should reduce your assessment too.
Keep Your Property Record Accurate: The county’s database might have outdated information about your home. If it says you have a pool you don’t have, or lists your square footage incorrectly, request a correction. Errors in their records are grounds for assessment reduction.
Monitor Market Trends: If your neighborhood has experienced a decline in property values (which is rare but possible), that’s evidence you can use in an appeal. Keep tabs on recent sales in your area.
Consider a tax levy impact analysis: If your county implements special assessments or district levies, understand how they affect your bill. Sometimes you can challenge these separately from your base assessment.
Another strategic consideration: understand whether tax allocation districts apply to your property. These can affect your overall tax burden and may have appeal options you’re not aware of.
Homestead Exemptions & Senior Programs
Let’s dive deeper into these programs because they can save you serious money.
Homestead Exemption Basics: Virginia’s homestead exemption allows you to reduce your assessed value by up to $25,000 if your primary residence is in Fairfax County. This applies to county taxes only (not school taxes). At the current rate of $0.82 per $100, that’s $205 in annual savings. Over a 30-year mortgage, that’s $6,150 in total savings—just for filling out a form.
You have to apply. It doesn’t happen automatically. Contact the Tax Assessor’s office and request the homestead exemption application. You’ll need to prove that the property is your primary residence.
Senior Citizen Tax Relief: If you’re 65 or older and have owned your home for at least two years, Fairfax County has programs that can significantly reduce your tax burden. Income limits apply (typically around $60,000-$75,000 depending on the program), but if you qualify, the relief can be substantial.
Some seniors get their tax frozen at the level it was when they turned 65. Others get outright reductions. The exact benefit depends on your income and the program you qualify for.
Disabled Veterans: If you’re a veteran with a service-connected disability rated by the VA, you may qualify for a property tax exemption. The amount of the exemption depends on your disability rating (10%, 20%, 30%, etc.). A 100% disabled veteran can get a full exemption on their primary residence.
These programs require applications and documentation, but they’re worth pursuing if you qualify. The county’s tax assessor’s office can walk you through the process.
Frequently Asked Questions
What is the current Fairfax County real estate tax rate for 2024?
– The current rate is $0.82 per $100 of assessed value. This applies to county taxes only; school taxes are assessed separately. On a $500,000 home, you’d pay roughly $4,100 per year in county real estate taxes.
How often does Fairfax County reassess property values?
– Fairfax County conducts a comprehensive reassessment every four years. The last full reassessment was in 2020, with updates in 2022 and 2024. You receive an assessment notice annually, but the value can change year to year based on market conditions and property updates.
Can I appeal my assessment if I think it’s too high?
– Yes, absolutely. You have 30 days from the date of your assessment notice to file an appeal with the Board of Equalization. You’ll need to provide evidence (appraisals, comparable sales, documentation of defects) to support your claim. The process is free and typically takes 60-90 days.
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 your home would actually sell for. They’re often different. Your assessed value might be lower or higher than market value depending on market conditions and the county’s appraisal methods.
Do I qualify for the homestead exemption?
– If your primary residence is in Fairfax County and you own the property (or are buying it), you likely qualify. You have to apply—it’s not automatic. Contact the Tax Assessor’s office to request an application. There’s no income limit for the basic homestead exemption.
What happens if I miss the 30-day appeal deadline?
– You’re locked into that assessment for another year. You can appeal again next year when you receive your next assessment notice, but you can’t go back and appeal the previous year’s assessment. This is why it’s critical to mark your calendar when you receive your notice.
Can property improvements increase my assessed value?
– Yes. If you add a room, renovate your kitchen, or make other significant improvements, the county will likely increase your assessed value. This is why it’s important to weigh the benefit of improvements against the potential tax increase. A $50,000 kitchen renovation might increase your assessed value by $40,000-$50,000, resulting in higher annual taxes.
Are there tax relief programs for seniors in Fairfax County?
– Yes. If you’re 65 or older, own your home for at least two years, and meet income requirements, you may qualify for significant tax relief. Some programs freeze your tax at a certain level; others provide outright reductions. Contact the Tax Assessor’s office for details on current programs and income limits.
What documents do I need to file an appeal?
– You’ll want a recent appraisal, comparable sales data for your neighborhood, documentation of any property defects, and your assessment notice. Photos of condition issues are helpful. You don’t need all of these, but the more evidence you have, the stronger your case.
How much can my assessment be reduced if I win an appeal?
– There’s no fixed amount. It depends on the evidence you present. Some homeowners get reductions of 5-10%; others get 20% or more if the county made a significant error. On average, successful appeals result in reductions of 10-15% of the assessed value.
