How to Appeal Your Property Tax Assessment in Northern Virginia

Every year, Northern Virginia homeowners open their assessment notice and wonder where the number came from. Most assessments are reasonable. But mass appraisal models can miss things like a dated kitchen, a busy road or a foundation problem. If your assessment is higher than what your home would actually sell for, an appeal can lower your tax bill for the year.

How assessments are made

Local assessors value thousands of homes at once using sales data, property records and models. They usually don’t walk through your home. That means their records can be wrong on square footage, bedroom count, finished basement space or condition. Errors in the record are the easiest thing to fix.

The three levels of appeal

Step	Who decides	What to expect
1. Administrative review	Your local assessor’s office	Usually a written request with evidence. Fastest and most common.
2. Board of Equalization	A board of local residents	A hearing where you present your case if step 1 didn’t resolve it.
3. Circuit court	A judge	Formal and costly. Rarely worth it for a typical home.

Each city and county sets its own deadlines, and they are often only weeks after notices are mailed early in the year. Check your assessor’s website the day your notice arrives.

Evidence that works

1. Fix factual errors first. Compare the county’s record with your home: square footage, bedrooms, baths, lot size and finished space.
2. Use three to five recent sales. Pick homes close by, similar in size, age and condition, sold close to January 1 of the assessment year.
3. Document condition. Photos and contractor estimates for a failing roof, foundation cracks or water problems matter.
4. Note location issues. Backing to a major road, power lines or commercial property can lower value.
5. Be specific. Ask for a specific value and show how you got there.

A worked example

Say your Fairfax County home is assessed at $820,000. Three similar homes on nearby streets sold for $775,000, $782,000 and $790,000 around the start of the year, and yours has an older kitchen than all three. You request $780,000. If the county agrees, your assessment drops by $40,000.

Item	Amount
Assessment reduction	$40,000
Tax rate	About $1.12 per $100
Yearly savings	$40,000 × 1.12 ÷ 100 = $448

That savings applies to the year you appealed. Next year starts with a new assessment, so the benefit doesn’t automatically carry forward, but a corrected record often keeps future values more accurate.

How to write a strong request

Keep it short and organized. Start with the value you believe is correct. List each comparable sale with its address, sale date, price, square footage and a one-line note on how it compares to your home. Attach photos of any condition problems and any contractor estimates. Finish with a clear summary: “Based on these sales and the condition issues shown, I request an assessed value of $780,000.” Assessors review many requests, and a clear one is easier to approve.

Common mistakes

• Arguing that taxes are too high. The appeal is about value, not the tax rate.
• Using sales from a different neighborhood or a much newer home.
• Relying on an online estimate as your main evidence.
• Missing the deadline, which ends the appeal for that year.
• Comparing your assessment to a neighbor’s assessment instead of to actual sales.

Assessed value and market value aren’t the same thing, which matters when you buy as well. See why you shouldn’t base an offer on tax assessed value and how a comparative market analysis works.

Frequently asked questions

Can my assessment go up if I appeal?

It’s possible in some localities if the review finds your home was under-assessed. That’s one more reason to start with solid sales data.

Do I need a lawyer or appraiser?

Not for most homes. A clear request with good comparable sales is usually enough. An appraisal can help for unusual or very high value properties.

Should I appeal if I just bought the home?

If you paid well below the assessment in an arm’s-length sale close to January 1, your purchase price can be strong evidence.
