Loudoun County Property Tax Rate: How to Read It
Loudoun County publishes annual rates for real and personal taxable property. This guide explains where to check the official 2026 rate and how to use it to estimate a real property tax bill.
What is the Loudoun County property tax rate?
What is the Loudoun County property tax rate?
“Loudoun County property tax rate” can refer to more than one rate.
For example, a question about a home concerns real property, while a question about a vehicle or other personal property should be checked against the personal-property category. The county page lists both categories, but the information provided here does not include the actual rate figures. That means this overview can point you to the right place to verify a rate, but it cannot supply a specific amount.
When looking up a figure, make sure it is labeled for the property type you have in mind. A real-property rate and a personal-property rate are not interchangeable simply because both appear on a property-tax page. The county also identifies a history of the percentage of personal property tax relief on that page. [1] For more detail, see . How to Pay Los Angeles County Property Tax Online.
Be careful when a third-party website presents an “effective” property-tax rate. An estimate described that way is not, by itself, the county’s adopted rate. For the county rate, use the county’s own rate page and match the listed category to the property you are researching. If a source gives an effective-rate estimate but does not identify it as the county’s published rate, keep the distinction clear rather than treating the estimate as the adopted figure.

This section does not quote a numeric rate because the supplied county-page information identifies the rate categories, not their amounts.
Where to check the current rates
Start with the county’s rates page
It is the starting point for checking the county’s published property tax rates, rather than relying on an old article, a search snippet, or a number copied without its tax year. [1]
Before using a rate, confirm that you are looking at the tax year that applies to your question. The page is titled for 2026, so don’t assume its figures describe another year. Then check the property category: the county page presents rates for both real taxable property and personal taxable property. A rate shown for one category should not be treated as the rate for the other.
A practical way to use the page is to match the year and category to the property you’re checking, then record the rate alongside those labels. If you’re checking personal taxable property, use that category instead. This simple habit makes it easier to compare figures accurately and spot when a page or saved note may refer to a different year or type of property.
The page also provides rate history and information about personal property tax relief. Those are useful when you need context beyond the current rate: the history lets you review earlier rates, while the relief information relates specifically to personal property. Check those sections separately from the current rate listings, and avoid treating historical figures or relief information as though they were the current rate for every property category.
If you’re uncertain which category applies to a particular property, confirm the classification before comparing rates. The key checks are straightforward: use the county’s official page, verify the tax year, and match the listed rate to the correct property category. [1]
How a rate per $100 of assessed value works
A rate stated “per $100 of assessed value” is applied in $100 increments of the assessed value. For a simple estimate, divide the assessed value by 100, then multiply by the rate per $100. That gives an illustrative tax amount before any other bill details are considered.
Both inputs here are assumptions for demonstrating the arithmetic; this is not a statement of the current rate or the assessment for any particular property.
Loudoun County’s rate page lists rates for real taxable property and personal taxable property. A 2025 report on the county budget described a real estate rate moving from $0.865 per $100 of assessed value to $0.805 per $100. That reported example shows why it matters to use the rate that applies to the relevant tax period rather than carry forward an older figure. To go further, see Alabama property tax rate: how it’s calculated and who pays.
This section’s simple calculation uses only an assumed value and assumed rate; it does not account for other details that may affect what a particular property owner ultimately owes.
Estimate a real property tax bill
Start with the rate for the right year
To estimate a real property tax bill, first find the official real property rate for the year you need. Loudoun County’s tax-rate page lists rates for real taxable property and personal taxable property, so use the real-property rate for this estimate—not a personal-property rate. The page is titled “Property Tax Rates 2026”; check the county’s page for the relevant year rather than assuming a rate applies across years. [1]
Calculate an estimate
Use this formula: assessed value ÷ 100 × real property rate. Those figures are only an illustration of the arithmetic, not Loudoun County’s rate or a prediction of a bill.
For a useful estimate, enter the property’s actual assessed value and the official rate for the year being reviewed. The source page supplied here does not provide a specific rate or assessment, so it is not enough to calculate a supported dollar amount. Confirm the rate on the county page before using it in your calculation. [1]
Check the property details
After calculating, confirm with the county whether any applicable adjustments affect the property or the amount due. Keep the tax year, real-property rate, and actual assessment together as you review the estimate. If you do not have one of those inputs, avoid filling the gap with a guess. The county page also describes a history of the percentage of personal property tax relief; that information is distinct from the real-property rate used in this calculation. [1]
Adopted rate versus effective tax rate
The adopted rate and an effective-rate estimate are not the same measure. The adopted rate is the county’s published rate for taxable property, and Loudoun County’s official rate page lists rates for real taxable property and personal taxable property. [1] Start with that page when you need the county’s published rate, and use the property category that fits your comparison. [1]
An effective-rate figure is a separate estimate. Outside sources report different figures: SmartAsset describes an average effective tax rate of 0.79%, while Ownwell reports an effective rate of 0.87%. [2][3] Keep these figures labeled as outside estimates; neither should be presented as the county’s adopted rate. The summaries provided do not explain enough about their underlying data or methods to show why the estimates differ. [2][3]
For a clear comparison, use separate labels such as “county published rate” and “outside effective-rate estimate.” If you include an effective-rate figure, retain its source and avoid implying that it is the rate listed on the official county page. [1][2][3] For example, a table could place the county figure in one column and an estimate in another, with each measure and source identified. That format helps readers see that the figures answer different questions rather than treating one as confirmation of the other.
Use the county rate page for the adopted rate, not an outside average. [1] If a source does not describe how its effective-rate estimate was calculated, do not infer what data it includes or how it applies to a particular property. Instead, present the estimate with its source and method limitations, and keep it distinct from the official county rate.
Frequently asked questions
Where can I find Loudoun County’s official rates?
Use Loudoun County’s official Property Tax Rates page to look up the published rates for the tax year shown on the page. It also provides a history of the percentage of personal property tax relief. Check the page itself rather than relying on an older article, saved note, or search snippet: the relevant figures are the ones published for the year you are reviewing. The source page does not provide the rate amounts in the text available here, so this section does not repeat a number.
Are real and personal property rates the same?
Treat them as distinct entries when you review the rate table; do not assume a rate shown beside one category applies to the other. The page also identifies personal property tax relief separately, as a history of its percentage. If you are checking a vehicle or another personal taxable property item, look for the personal-property entry and any relevant relief information rather than using the real-property listing. The source confirms that these categories and relief history are available, but does not give the specific rates or explain how relief is calculated.
How can I confirm which rate applies to my property and tax year?
Start with the county’s rates page and match the property category and tax year to the information you need. If you are unsure which category describes your property, or whether a relief entry affects your bill, confirm with the county before relying on a rate. For example, someone checking a home should compare the real-property listing, while someone checking personal taxable property should use that category’s entry; the page’s category labels help keep those checks separate. This source does not explain individual assessments or bills, so use the county’s applicable tax information for questions about your specific account.
Check the official rate before estimating
Before using a figure for the loudoun county property tax rate, check the county’s official Property Tax Rates page. It identifies rates for real taxable property and personal taxable property, so first make sure the category you are looking at matches the property in your estimate. [1]
Then match the rate to the tax year you need. The cited page is titled “Property Tax Rates 2026,” but that title alone does not establish the rate for another year or tell you which year applies to a particular bill. [1] If you are reviewing a bill or planning an estimate, use the relevant year shown by the county rather than carrying a figure over from a different year.
Keep the calculation clearly labelled as an estimate until you have checked it against the county’s current information. For example, if you are estimating tax on a home, use the real taxable property category; for a personal taxable property estimate, use that category instead. These are different categories on the county page, so do not substitute one for the other. [1] The source page does not provide a specific rate in the material available here, so this section does not quote one.
The page also describes a history of the percentage of personal property tax relief. [1] Treat that as a separate item to check when it is relevant to your calculation; do not assume a relief figure is itself the property tax rate.
In short: confirm the tax year, select the matching property category, and use the county’s official rate page as the final reference. If the rate or category is unclear, verify it with county information before relying on the estimate. That keeps the result useful without presenting an unchecked calculation as a confirmed amount.
