How to read your property tax assessment notice line by line

Last updated 2026-07-09

What is a property tax assessment notice and why does it matter?

A property tax assessment notice is the official document your county assessor mails to tell you what they think your property is worth for tax purposes. Depending on your state it goes by Notice of Assessment, Notice of Value, or Annual Notice of Assessment. That value, once finalized, is the number the taxing authority multiplies against the local rate to produce your bill.

The notice is not your tax bill. This is the single most common confusion homeowners have. The notice tells you the assessed value. The bill comes later, usually from a separate county treasurer or tax collector office, after governing bodies set their budgets and finalize the levy rate. ^[1]

Here is why the notice matters so much. If you disagree with the assessed value, you generally must appeal within a tight window after the notice is mailed, not after the bill arrives. Miss that window and you are locked into the value for the year. Deadlines range from as few as 30 days in some jurisdictions to 90 days or more in others, and some states tie the deadline to the notice date rather than when you actually received it. ^[2]

Read each line and you can check three things: whether the assessor used accurate data, whether your exemptions posted, and whether the math holds. Most assessment errors fall into a small number of categories. You can find most of them in under an hour with your notice in hand.

What do all the lines on an assessment notice actually mean?

Notices vary by county, but nearly every one in the United States carries the same underlying data points, just in a different order or under different labels. Here is what each line means and what to check.

Owner name and mailing address. Seems obvious. Check it anyway. A wrong mailing address means future notices go somewhere else and you miss a deadline. A wrong owner name matters if the property changed hands recently and the transfer was not yet recorded.

Parcel number (APN, tax account number, property ID). The unique identifier the county uses for your lot. Every record in the county system ties to this number. Write it down. You will need it for any appeal.

Property address and legal description. Verify the address matches your property. The legal description (lot, block, subdivision, or metes-and-bounds) tells you exactly what land parcel the assessment covers. If it includes a neighbor's garage or misses part of your lot, the value is wrong.

Property class or use code. Counties classify property by use: residential, commercial, agricultural, vacant land, and so on. The class decides which assessment ratio and which tax rate apply. A residential property accidentally coded as commercial can produce a wildly different bill. ^[3]

Land value. The assessor's estimate of the underlying land alone, no structures. In most states land and improvement values are assessed separately and reported separately on the notice.

Improvement value (building value). The assessor's estimate of everything built on the land: house, garage, deck, fence, pool. This line is where most residential disputes start, because the assessor estimates what your structure is worth using mass appraisal models instead of inspecting your specific home.

Total assessed value (market value or full value). Land value plus improvement value. In states that assess at 100 percent of market value, this number is supposed to approximate what your home would sell for on the open market. California under Proposition 13 is the big exception; most other states at least claim 100 percent. ^[4]

Assessment ratio or level of assessment. Some states do not tax the full market value. They apply a statutory ratio to reach the taxable base. Illinois assesses most residential property at 10 percent of market value in Cook County and 33.33 percent in other counties under 35 ILCS 200/9-145. ^[5] If your state uses a ratio, this line shows which one applies.

Assessed value after ratio (equalized assessed value, EAV, or taxable assessed value before exemptions). Market value multiplied by the ratio. In Illinois this is the Equalized Assessed Value (EAV), and it is the number exemptions subtract from. In 100 percent states, this line equals the total assessed value.

Exemptions. Any exemptions you qualify for are listed here, each cutting the taxable value. Common ones: homestead/homeowner, senior, veteran, and disability exemptions. The dollar amounts shown are reductions to your taxable value, not reductions in your actual tax. ^[6] Check that every exemption you applied for actually appears and that the amounts match what your state statute allows.

Net taxable value. Assessed value after ratio, minus all exemptions. This is the number the tax rate hits. Get it wrong and every downstream calculation is wrong.

Tax rate or mill rate. Usually not on the assessment notice itself, since it is set later, though some jurisdictions print a preliminary or prior-year rate for reference. A mill is one-tenth of one cent, or $1 per $1,000 of taxable value. A rate of 20 mills means $20 per $1,000, or 2 percent of taxable value.

Estimated tax or prior-year tax. Some notices include an estimate based on last year's rate. Treat it as directional only. The final bill reflects the new levy rate once budgets are adopted.

Appeal deadline and instructions. Almost always at the bottom or on the back. Read this before anything else. The deadline is the most important thing on the document.

What is the difference between market value, assessed value, and taxable value?

These three terms trip up most homeowners, and mixing them up leads to confusion about what you can actually appeal.

Market value (also called full cash value or fair market value) is what the assessor believes your property would sell for between a willing buyer and a willing seller, neither under pressure. That is the starting point.

Assessed value is market value adjusted by your state's assessment ratio. If your state assesses at 100 percent, assessed value equals market value. If your state assesses at 10 percent, like Cook County residential property, a $400,000 home has a $40,000 assessed value. ^[5]

Taxable value is assessed value minus any exemptions. Take the Texas homestead exemption, where the state allows a $100,000 reduction on school district taxes as of 2023 under Texas Tax Code Section 11.13(b). ^[7] That knocks $100,000 off your assessed value before the rate applies.

When you appeal, you are almost always appealing the market value the assessor assigned. Bring that number down and every downstream figure adjusts automatically. You generally cannot appeal the tax rate, the assessment ratio, or the levy amount. Different governmental bodies set those through different processes.

Term	What it is	Who sets it	Can you appeal it?
Market value	Estimated sale price	County assessor	Yes, this is what you appeal
Assessment ratio	Statutory percentage	State legislature	No
Assessed value	Market value × ratio	Math	Not directly
Exemptions	Statutory reductions	You must apply	You can apply if missing
Taxable value	Assessed value − exemptions	Math	Not directly
Tax rate / mill rate	Budget ÷ tax base	Taxing bodies	No (different process)

How do you check whether the assessor's property description is accurate?

The second page of most notices, or a separate attached sheet, lists the physical characteristics the assessor recorded for your property. It goes by property record card, assessment card, or field data. In many counties you can pull it from the assessor's online portal using your parcel number. ^[1]

Check every line against what you actually have.

Square footage. If the assessor has your home at 2,200 square feet and it is actually 1,950, you are paying on 250 square feet of house that does not exist. These errors are common because assessors lean on permit records or old sketches instead of re-measuring. Measure your home (finished living space only, not the garage) and compare.

Bedroom and bathroom count. Each extra bedroom or bathroom adds value in a mass appraisal model. If you have three bedrooms and the record says four, that is phantom value on your bill.

Garage. Attached versus detached, finished versus unfinished, the number of cars, and whether it has heat all move the assessed value. Check each.

Year built. Wrong year built throws off the depreciation calculation. Older homes typically depreciate more under a cost approach.

Basement finish. Finished basement square footage is usually valued at a lower per-square-foot rate than above-grade space. Verify the assessor classified yours correctly.

Lot size. Cross-check against your deed or a plat map from the county recorder. An extra 0.1 acres of land value can matter in some markets.

Pool, outbuildings, solar. Each is a line item. If something listed does not exist, flag it. If something exists that is not listed, you do not need to volunteer it. Stick to errors that hurt you.

Found discrepancies? Document them with photos, your original closing documents, or a licensed appraiser's sketch. Those facts alone, without any comparable sales analysis, can carry an appeal.

Which exemptions should appear on your notice, and what happens if one is missing?

Exemptions are money on the table that many homeowners walk past. If an exemption you qualify for does not appear on your notice, you are almost certainly overpaying, and in most states you can apply retroactively for at least one or two prior years. ^[6]

The most common residential exemptions:

Homestead exemption. Available in most states for a primary residence. Texas allows a $100,000 homestead exemption on school district taxes under Tax Code Section 11.13(b) as of 2023. ^[7] Florida caps the annual assessed-value increase on a homestead property at 3 percent or the CPI change, whichever is less, under Article VII Section 4 of the Florida Constitution (the Save Our Homes cap). ^[8] The savings swing enormously by state and county.

Senior citizen exemption. Many counties offer an extra reduction for homeowners over a certain age, often 65, sometimes with an income cap. Cook County, Illinois offers a Senior Citizen Homestead Exemption that cuts EAV by $8,000 as of 2024. ^[9]

Senior freeze (senior citizens assessment freeze). Separate from the senior exemption. This locks the assessed value for seniors who meet income thresholds so it cannot rise above the frozen amount no matter what the market does.

Veteran and disabled veteran exemptions. These run from small reductions to a full exemption from property tax for 100 percent service-connected disabled veterans. Texas exempts 100 percent disabled veterans from all property taxes under Tax Code Section 11.131. ^[7]

Disability exemption. For homeowners with qualifying disabilities, separate from the veteran benefit.

Agricultural or greenbelt assessment. If you have acreage in qualifying agricultural use, the land may be assessed at its agricultural value instead of its market value.

If an exemption is missing, go to your county assessor's website, download the application, submit it, and follow up in writing. Keep a copy of everything. If the assessor confirms you were eligible in prior years, ask about a retroactive refund. Most states allow refund claims going back at least two years, some longer.

How do you check the math from assessed value to estimated tax?

Once you have read each line, confirm the arithmetic ties together. Run this sequence:

1. Land value + Improvement value = Total market value. Check the addition. 2. Total market value × assessment ratio = Assessed value (EAV or equivalent). A 100 percent state uses a 1.0 multiplier. 3. Assessed value − all exemption amounts = Net taxable value. 4. Net taxable value × tax rate = Estimated tax. (If the rate is in mills, divide by 1,000 first.)

Here is a worked example. A home with a $350,000 market value in a state with a 33.33 percent ratio has an assessed value of roughly $116,655. If the homestead exemption is $6,000, the taxable value is $110,655. At a mill rate of 8.5 ($8.50 per $1,000), the tax is $110,655 × 0.0085 = $940.57.

If the number on your notice does not match your math, you have found a calculation error, in your favor or against you. Either way, contact the assessor's office before the appeal deadline. Calculation errors are usually corrected without a formal hearing.

Many county portals let you run the calculation interactively where the bill is paid online. See guides for specific counties like Cook County tax assessor tax bill and LA County property tax for county-specific bill breakdowns.

What does the assessment ratio line mean and how does it affect what you pay?

The assessment ratio (also called the level of assessment or assessment level) is the percentage of market value the state or county uses as the taxable base. It exists mostly for historical and political reasons. Keeping the stated assessed value low while nudging the tax rate up raises the same revenue, but the smaller number looks less alarming to homeowners.

In practice, the ratio matters because exemption amounts come off the assessed value, not the market value. If your assessed value is only 10 percent of market value, a $6,000 exemption cuts your taxable base by $6,000, which at a 7 percent effective rate saves you about $420. The same exemption against a 100 percent assessed value saves the same dollars only if rates were calibrated identically.

Where the ratio really creates problems is inequity across property classes. If commercial property is effectively assessed at a higher percentage of its actual market value than residential property (a common finding in the academic literature on assessment uniformity), homeowners come out relatively ahead. The reverse is also documented. ^[10]

For your appeal, the ratio changes nothing about what you have to prove. You still show that the assessor's market value is wrong. The ratio then applies on its own. Some states, Illinois among them, add a separate equalization factor (the "state multiplier") applied by the Illinois Department of Revenue to pull countywide assessments up to the legally required one-third of market value. If that factor moves year to year, your assessed value can jump even though your home's market value did not. ^[5]

What are the most common errors to look for on an assessment notice?

Most overpayments trace back to a handful of repeating errors. Here they are, roughly in order of how often they show up.

1. Wrong square footage. The most common error, and often the most valuable to catch. Assessors use permit data, sketches from prior appraisals, or MLS records, all of which can be stale or flat wrong. A 10 percent square footage error on a median-priced home flows straight into a real over-assessment.

2. Missing exemption. Homestead exemptions that never posted (often because you bought the home after the filing deadline and forgot to re-apply), senior exemptions nobody ever filed for, or veteran exemptions applied for but processed wrong.

3. Wrong property class. A vacation home assessed as a primary residence (missing the homestead benefit), or a rental accidentally coded as owner-occupied, can swing the value hard.

4. Condition not reflected. Mass appraisal models assign a condition rating. If your home has a failing roof, outdated systems, or deferred maintenance and the assessor rated it "average" instead of "fair" or "poor," the value is too high. Bring evidence: contractor estimates, inspection reports, photos.

5. Market value too high relative to sales. Even with perfect data, the model can just be wrong about your neighborhood's price level. Pull three to five recent sales of genuinely comparable homes (similar size, age, condition, location) and see where your assessed value lands against those prices. If your assessed value tops what comparable homes actually sold for, that gap is your argument. ^[2]

6. Prior year's value not carried forward. If you won an appeal last year, the corrected value should become the base. Sometimes it does not. Check that the prior value on your new notice reflects what was ordered after your appeal, not the original higher number.

When is the appeal deadline and how do you find it?

The appeal deadline is the most legally serious date on your notice. Statutes are unforgiving. Miss it and you lose the right to contest the value for that tax year, full stop. ^[2]

The deadline usually prints on the face of the notice, near the bottom, or on a detachable stub. If it is not there, your county assessor's website has it. Look for "appeal deadline," "protest deadline," or "petition period." The deadline almost always runs from the notice date, not the date you opened the envelope, so do not sit on it.

Here is a rough sense of how deadlines vary. These are approximations for the most common states. Confirm your specific county's date before you act. ^[3]

State	Typical appeal deadline (residential)	Measured from
Texas	May 15 or 30 days after notice, whichever is later	Notice date
California (Prop 13 counties)	November 30 of assessment year	Fixed annual date
Illinois (Cook County)	Varies by township (roughly April-July)	Township schedule
Florida	25 days from TRIM notice (mailed mid-August)	Notice date
New York City	March 15 (small homes)	Fixed annual date
Georgia	45 days from notice date	Notice date

Miss the formal window and your options narrow fast. Some states have a correction process for clerical or factual errors (wrong square footage, wrong owner) that runs outside the appeal window. Ask the assessor's office specifically about "correction" versus "appeal" procedures. But do not count on it. File before the deadline.

For county-specific deadline details, see county guides like Gwinnett County tax assessor or Bexar County tax assessor.

How do you compare your assessed value to what similar homes sold for?

The strongest evidence in a residential appeal is a set of comparable sales (comps) showing that similar homes sold for less than what the assessor says your home is worth. Here is how to build that case from your notice.

Start with your assessed value. In a 100 percent state, that number is what you compare to sale prices. In a ratio state, convert first: divide the assessed value by the ratio to get the implied market value the assessor assigned, then compare that to sale prices.

Work an example. If your EAV is $85,000 and your county's ratio is 33.33 percent, the implied market value is $85,000 / 0.3333 = $255,015. Now find recent sales of comparable homes. If they sold for $220,000 to $240,000, you have a strong over-assessment argument.

Where to find comps:

• Your county assessor's own online sales database (most publish one; it is public record)
• Zillow, Redfin, or Realtor.com for recent solds (usually within 12 months)
• Your state's deed recording database, which is public record

What makes a good comp:

• Same general neighborhood or subdivision (within roughly one mile for urban areas, broader for rural)
• Similar square footage (within about 15 to 20 percent)
• Similar age, condition, and features
• Sold within 12 months of the assessment date

Three to five good comps usually do the job. More does not always help. One or two outlier low sales can weaken your case if the assessor challenges their comparability. Be selective. Document each sale with the address, sale date, sale price, square footage, and source. ^[2]

For county guidance on pulling comparable sales, Montgomery County property tax and Hennepin County property tax both point to county databases worth bookmarking.

What should you do immediately after reading your assessment notice?

Do these in order, preferably the day the notice arrives.

Step 1: Note the appeal deadline. Write it on your calendar, set a phone reminder, whatever works. Everything else is secondary.

Step 2: Pull the property record card. Go to your assessor's website, enter your parcel number, download or print the full record card. Compare every physical characteristic to your home.

Step 3: Check for missing exemptions. Read each exemption line. If the homestead exemption is absent and you live there as your primary residence, call the assessor's office right away. This is often fixable before the deadline with minimal paperwork.

Step 4: Look up the implied market value. Do the ratio math if needed. Compare it against what you know about recent sales in your area.

Step 5: Decide whether to appeal. If the assessed market value sits within 5 percent of what you think is fair, the cost of your time probably outweighs the savings. If the gap is 10 percent or more, the appeal is worth pursuing. In many jurisdictions, filing a simple administrative appeal is free and takes only a short form plus your evidence. ^[2]

Step 6: Gather evidence now. Pull three to five comparable sales. Take photos of any condition issues. Compile the record card with your documented corrections. The window is short and evidence gathering takes longer than people expect.

The appeal itself, in most counties, is a short informal hearing or a written submission. You do not need an attorney. You do not need an appraiser, though one helps in complex cases. What you need is organized, factual evidence that the assessor's number is too high.

What does your property tax assessment notice look like in specific major counties?

Notices are not standardized nationally, so the layout shifts county to county. Here is what to expect in a few big ones.

Cook County, Illinois. Cook County sends a separate reassessment notice from the assessor's office and a later tax bill from the Cook County Treasurer. The reassessment notice shows your property class, prior assessed value, new assessed value, and the appeal deadline. The EAV runs roughly 10 percent of market value for residential class 2-00 properties. ^[5] See Cook County tax assessor tax bill for the full breakdown.

Los Angeles County, California. Under Proposition 13, the assessed value grows by no more than 2 percent per year unless the property transfers or is substantially improved. ^[4] The notice shows the prior year value, the 2 percent factored base year value, and any supplemental value from a recent sale or construction permit. The regular roll appeal period runs July 2 through November 30. See Los Angeles County property tax for specifics.

New York City. NYC notices show market value, assessed value (capped at 45 percent of market value for large income-producing properties; residential Class 1 homes are capped differently), and transitional assessed value. The deadline for most small residential properties is March 15. ^[11] See NYC property tax for more detail.

Texas (for example, Bexar County). The Central Appraisal District sends a Notice of Appraised Value. Texas assesses at 100 percent of market value. The notice lists market value, assessed value (which may be lower if a homestead cap applies), and the exemptions. The protest deadline is May 15 or 30 days from the notice date. ^[7] See Bexar County tax assessor.

Santa Clara County, California. The Assessor's Office sends an annual notice for properties that had value changes. The notice shows the prior value, the new value, and the grounds and deadlines for appeal to the Assessment Appeals Board. ^[12] See Santa Clara property tax.

Frequently asked questions

What is the difference between the assessment notice and the tax bill?

The assessment notice shows the value the assessor placed on your property. The tax bill, sent separately and often months later, applies the tax rate to your taxable value to show what you owe. You appeal the assessment. You pay the bill. Miss the assessment appeal deadline and you cannot challenge the value that produced the bill, so read the notice first.

How do I know if my property is assessed too high?

Convert your assessed value to an implied market value (divide by your state's assessment ratio). Then look up three to five recent sales of comparable homes in your neighborhood. If those homes sold for meaningfully less than the assessor's implied market value for your home, usually 10 percent or more, you likely have grounds for an appeal. Free sales data sits on most county assessor websites.

What is a homestead exemption and how do I check if mine is applied?

A homestead exemption reduces the taxable value of your primary residence, lowering your tax bill. It shows as a line item under exemptions on your notice. If you own and occupy the home as your primary residence and no homestead exemption appears, contact your assessor's office right away. Most counties require a one-time filing that stays in effect as long as you own the home.

Can I appeal just the physical description errors without doing a full comparable sales analysis?

Yes. Many assessment offices have an informal correction process for clear factual errors: wrong square footage, missing rooms, a pool that does not exist, incorrect lot size. You can often fix these with a simple request and supporting documentation (photos, your closing survey, permit records) without a formal hearing. Correcting the data often produces a value reduction on its own.

What is the assessment ratio and does it differ by property type?

The assessment ratio is the percentage of market value used as the taxable base. It varies by state and sometimes by property class within a state. In Illinois, residential property in Cook County is assessed at 10 percent of market value while commercial property is assessed at 25 percent under 35 ILCS 200/9-145. In Texas and California, the stated ratio is 100 percent of market value, though California's Proposition 13 caps annual increases.

What does 'equalized assessed value' (EAV) mean on my Illinois notice?

EAV is the assessed value (already reduced by the Cook County assessment ratio) further multiplied by the state equalization factor set each year by the Illinois Department of Revenue. The goal is to pull assessments statewide up to the required one-third of market value. Your exemptions then subtract from EAV to produce your net taxable value. Exemptions and tax rates both apply to EAV, not to market value.

How far back can I apply for a missed exemption?

It depends on your state. Most states let you claim retroactive refunds for at least two prior tax years for an exemption you qualified for but did not receive. Some allow three years; a few allow only the current year. Contact your assessor's office and ask specifically about retroactive applications. File sooner rather than later, because statutes of limitations do apply.

What if my appeal deadline has already passed?

Your options are limited but not zero. Some states have a separate correction or abatement process for factual errors (wrong ownership, wrong property description, clerical mistakes) that runs outside the normal appeal window. A few states allow late filing for good cause shown. For next year, set a calendar reminder now. Your notice date starts the clock, so act within days of receiving it, not weeks.

Do I need a licensed appraiser to appeal my property tax assessment?

No, not for an informal or administrative appeal. A well-prepared set of comparable sales, printed from public sources and organized clearly, is usually enough evidence at the board of review or appraisal review board level. A licensed appraisal (costing $300 to $600 or more) becomes worth considering if your potential tax savings are large, the assessor disputes your comps, or you need to go to formal tax court.

What does the mill rate or mill levy on my notice mean?

A mill is $1 per $1,000 of taxable value. A mill rate of 15 means your annual tax is $15 for every $1,000 in taxable value, or 1.5 percent. To calculate: taxable value ÷ 1,000 × mill rate = annual tax. If your mill rate is not on your assessment notice, check your prior year tax bill or your county's budget documents. Taxing bodies set the rate after the assessment is finalized.

Can a commercial property owner use the same process to read and appeal their assessment?

The notice lines are largely the same, but the valuation method differs. Residential property is typically valued by the sales comparison approach; commercial property often uses the income approach (capitalized net operating income). Commercial appeals are more complex and the stakes are higher. The same first step applies: verify the physical data and confirm the property class and use code before you analyze the value.

What is a supplemental assessment notice and does it require a separate appeal?

A supplemental assessment is an added assessment triggered by a mid-year event, typically a purchase or new construction, that changes the property's value after the annual roll is already set. California issues supplemental assessments after a change in ownership under Revenue and Taxation Code Section 75. Yes, a supplemental notice has its own appeal deadline and requires a separate appeal filing if you disagree with it.

How do I find my county assessor's website to pull my property record card?

Search '[county name] assessor property search' or '[county name] appraisal district' in any search engine. Most county assessors have a parcel search tool on their homepage. Enter your parcel number (from your notice) or your property address. Download or print the full property record card, sometimes called the property detail or assessment card, which shows the physical data the assessor used.

What should I do if the owner name or address on my notice is wrong?

Contact both the county assessor and the county recorder (or register of deeds) in writing as soon as you can. A wrong mailing address means you may not receive future notices or tax bills, which can trigger missed deadlines or delinquency without your knowledge. A wrong owner name after a recent sale usually means the deed transfer has not processed yet. Confirm with the title company or attorney who handled your closing.
