How to fill out a notice of appeal for property taxes

Last updated 2026-07-11

What is a notice of appeal for property taxes and what does it actually do?

A notice of appeal is the document that formally opens your case before the local review board. Some states call it a petition for review, an appeal application, or a complaint form. Without it, nothing else you do matters. You can have perfect comparable sales, a professional appraisal, and a clean argument, but if the form is wrong or late, most boards dismiss the appeal before you say a word.

The form is short. Most run one to three pages. It asks who you are, what property you own, what the assessor says it's worth, what you think it's worth, and why. That's about it. The legal weight comes from the fact that you filed on time and the board now has jurisdiction to hear your case, not from length or wording.

Filing the notice does not reduce your tax bill by itself. It opens a hearing. The reduction comes later, if the board agrees with your evidence.

The notice is the gate. Miss it and the gate locks for the year.

Where do you get the correct appeal form for your county?

Start at your county assessor's website or your county board of equalization (BOE) website. These are two different offices in many states, and the form usually belongs to whichever body runs the first-level hearing. In California, the Assessment Appeals Board is a county-level body separate from the assessor ^[1]. In Cook County, Illinois, the Assessor's Office handles the first level and the Board of Review handles the second ^[2].

If you can't find the form online, call the assessor's main line and ask: "What form do I file to appeal my assessed value and where do I get it?" That question gets a direct answer almost every time. Our guide to the cook county tax assessor tax bill covers the Illinois specifics.

A few states use a single statewide form. Missouri routes residential appeals through the local Board of Equalization but publishes standardized complaint forms through the State Tax Commission ^[3]. Other states leave form design to each county, which means a Gwinnett County, Georgia form looks nothing like a Bibb County, Georgia form. Check gwinnett county tax assessor and bibb county tax assessor for county-specific guidance.

Never use last year's form without confirming it's still current. Boards update forms, sometimes in ways that change required fields, and an outdated form is one of the most common reasons an appeal gets tossed.

What is the deadline to file a property tax appeal notice?

The deadline is the single most important thing in this process. Miss it and you generally cannot appeal that year's assessment at all, no matter how wrong the number is.

Deadlines vary a lot by state and sometimes by county within a state. The window usually runs 30 to 90 days from the date the assessment notice was mailed, not from when you received it or when your tax bill arrived. That distinction costs people every year.

Here's a snapshot of real filing windows across major jurisdictions ^{[1][3][4][5][7][8]}:

State / Jurisdiction	Appeal window	Trigger event
California (most counties)	60 days from July 2 assessment roll opening	July 2 each year
Illinois (Cook County, Board of Review)	30 days from publication of township schedule	Varies by township
Texas	May 15 or 30 days from notice, whichever is later	Appraisal notice mailing
New York City	March 1 (Tax Commission)	Fixed annual date
Georgia	45 days from assessment notice	Notice mailing date
Florida	25 days from TRIM notice mailing	Usually August
Missouri	July 10 or within 30 days of notice	Notice mailing date

These dates move to the next business day when they land on a weekend or holiday. Always verify the exact date with your county's office for the current tax year. For Los Angeles, our la county property tax and los angeles county property tax guides carry the current windows.

Texas Tax Code Section 41.44 sets the deadline as "before June 1 or not later than the 30th day after the date that notice was delivered to the property owner, whichever is later" ^[4]. The notice mailing date is the clock, not your reading of the bill.

How do you fill out each field on a property tax appeal form?

Most forms share the same set of fields, even if the labels differ. Here's how to handle each one.

Owner name and mailing address. Use exactly the name on your deed or the current assessment roll, not a nickname or abbreviation. If the property is in a trust or LLC, use the entity name as it appears on the deed. A mismatch can send the hearing notice to the wrong address, and you miss your hearing without knowing it.

Parcel identification number (PIN or APN). Copy this straight from your assessment notice or tax bill. Don't guess and don't pull it from memory. One transposed digit means you're appealing the wrong parcel. The PIN is usually a 10-to-14 digit number, sometimes with dashes.

Property address. This is usually the situs address (the physical location of the property), not your mailing address if the two differ.

Current assessed value. This is the assessor's number, not what you think it's worth. Copy it from your assessment notice. Some forms ask for "land value" and "improvement value" separately. Use the figures from the notice for each.

Requested value or basis of appeal. This is where you state your position. Two approaches: state a specific dollar amount you believe is correct, or check a box for "overvalued" or "unequal appraisal" if your state offers that option. In Texas, unequal appraisal (your property assessed at a higher percentage of market value than comparable properties) is a separate statutory basis from plain overvaluation ^[4]. Knowing which box to check matters.

Reason for appeal. Most forms give you a short text box or a checklist. Common options: overvalued, unequal appraisal, incorrect property description, incorrect classification, and improper exemption denial. Check more than one if both apply. Keep the written reason brief. "Property is overvalued based on recent comparable sales" is enough. You make the full argument at the hearing, not on this form.

Signature and date. Sign and date the form yourself. If an agent signs, many jurisdictions require an attached authorization form. An unsigned appeal form is invalid in nearly every jurisdiction.

Agent or representative information. If you're doing this yourself, which is the whole point for most readers here, leave this section blank or mark it "self-represented." Don't fill in a tax agent's name unless you've actually hired one.

What are the most common mistakes people make on appeal forms?

Wrong parcel number. This is the top error. The form goes to the right address and the right name, but the PIN points to a neighbor's lot. The board processes it for the wrong property and your actual property never gets reviewed.

Filing to the wrong office. In states with multi-level appeal systems, filing with the assessor when you should file with the Board of Equalization (or the reverse) can kill the appeal. Know which body handles the first level in your jurisdiction.

Missing the deadline by one day. Boards are not sympathetic. A Georgia taxpayer who files on day 46 instead of day 45 after their notice is usually out of luck for the year, absent something like documented mail failure or a declared disaster ^[7].

Leaving the "requested value" blank. Some people file the notice just to get in line and plan to figure out their number later. Most forms require at least a value or a basis of appeal at filing. A blank field can trigger dismissal.

Attaching your full evidence packet to the notice. The notice is not the hearing. Stapling 40 pages of comparable sales to the filing form clutters the record and sometimes causes procedural problems if you need to amend your evidence later. Save the evidence for the hearing packet, which usually goes in separately.

Using an outdated form. Check the revision date, usually printed in small type at the bottom of the page. If it's two or more years old, confirm with the county that it's still accepted.

Do you have to state your evidence on the notice of appeal itself?

No. The notice of appeal is not the place to lay out your case. It's the door opener. You're telling the board: "I dispute this assessment and here's the general basis." The evidence, meaning comparable sales, appraisals, photos, construction cost estimates, income and expense statements for commercial property, comes later.

Most jurisdictions set a separate evidence deadline that falls before your hearing date. California counties commonly require the parties to exchange evidence at least 20 days before the hearing ^[1]. Texas has a formal evidence exchange requirement under Tax Code Section 41.67 ^[4].

You should know before you file whether you have a credible basis for appeal. Filing a notice with no plan for evidence wastes a year and maybe a small filing fee. To build your evidence package, the evidence and comps section of this site goes deep on comparable sales, appraisal reports, and what boards actually find persuasive.

TaxFightBack's DIY appeal kit bundles the form guidance with an evidence-building worksheet, so you're not solving the two pieces separately. The form itself is always free from your county.

Is there a filing fee and how do you pay it?

Many jurisdictions charge no filing fee at all for residential property tax appeals. California counties generally charge nothing for residential appeals to the Assessment Appeals Board ^[1]. Missouri's Board of Equalization process is also free at the local level ^[3].

Others do charge. New York City's Tax Commission charges no fee for most Class 1 (one-to-three family residential) properties but does charge for larger properties ^[5]. Some Texas Appraisal Review Boards require a deposit or fee for certain appeal types when the dispute exceeds a threshold.

When a fee applies, payment methods vary. Most counties now take check, money order, or online payment at filing. A few still want a check or cashier's check made out to the specific board. For online payment options generally, see our guide on online tax payment for property.

Lose your appeal and the filing fee is almost never refunded. Win it and the fee is rarely refunded either, though some jurisdictions return it if the assessor concedes before the hearing. Check your county's rules.

Can you file a property tax appeal online or does it have to be on paper?

This depends entirely on the jurisdiction, and the online options keep growing. As of 2024, a rising number of large counties accept electronic filing through a dedicated portal. Cook County's Board of Review has accepted online residential filings for several years ^[2]. Bexar County, Texas allows online appeals through the Bexar Appraisal District portal. See bexar county tax assessor for specifics.

Smaller counties and older BOE systems often still require paper filing, sometimes by hand delivery or certified mail. If the form must arrive by a certain date, certified mail is your safeguard because it creates a postmark record. Most jurisdictions treat the postmark date as the filing date, but not all. Some require actual receipt by the deadline. Read the form instructions or the county's appeal guide carefully.

Mail it certified with return receipt requested. Keep the receipt and your copy of the completed form together. If the board later claims it never got your appeal, the return receipt is your proof.

Email is almost never accepted as an official filing unless the county's own system generates a confirmation with a tracking number. A PDF sent to a generic assessor inbox is not a legal filing in most jurisdictions.

What happens after you submit the notice of appeal?

First, you should get an acknowledgment. Some counties mail a confirmation letter within a few weeks. High-volume jurisdictions like Los Angeles or Cook County may take months to send a hearing date. Don't read silence as rejection.

Most residential property tax appeal hearings land 3 to 12 months after the filing deadline closes, depending on caseload. In Cook County, the Board of Review processes hundreds of thousands of appeals a year, and wait times can stretch past a year ^[2]. In smaller counties, you might get a hearing within 60 days.

While you wait, your original tax bill is still due. Filing an appeal does not defer payment in most states. You pay the bill based on the disputed assessed value, and if you win, the county issues a refund or a credit toward future bills. Florida is an exception. Section 194.014 of Florida Statutes requires a taxpayer to pay the non-ad valorem taxes and at least 75 percent of the ad valorem taxes before the appeal can proceed to court ^[6].

Before the hearing, review what evidence the assessor used to reach your assessed value. Many jurisdictions let you request the assessor's property record card and comparable sales data ahead of time. Request it as soon as you file. It tells you exactly what you're up against.

For Hennepin County and Montgomery County taxpayers, the hearing procedures and evidence rules are in our hennepin county property tax and montgomery county property tax guides.

What if you make a mistake on the form after you've filed it?

The answer depends on when you catch the mistake and what kind it is.

A typo in your mailing address can usually be fixed by calling the board clerk and confirming the change in writing. A wrong parcel number is more serious and may need a formal amendment or a fresh filing if the deadline hasn't passed. Amending a pending appeal is generally allowed before the hearing date in most jurisdictions, but there's no universal rule.

If the deadline has passed and you find the error, call the clerk's office right away. Some boards can accept corrected filings within a short window after the deadline for clerical errors. Others cannot. The statute of limitations on property tax appeals is usually absolute. Courts in most states treat appeal deadlines as jurisdictional, meaning a board has no authority to hear a late-filed appeal regardless of the reason.

That's why twenty minutes of double-checking pays off. Read the form back against your assessment notice. Confirm the PIN digit by digit.

How do you fill out the notice of appeal for commercial or income-producing property?

The form is usually the same for commercial and residential property. The difference is how you establish value. Commercial property is typically assessed using the income approach (capitalized net operating income) rather than comparable sales alone. So on the basis-of-appeal line, you might note: "Property is overvalued; income approach indicates a lower value than assessed."

Some jurisdictions run separate forms or separate hearing tracks for commercial appeals. New York City separates Class 2 (residential income property) and Class 4 (commercial) appeals ^[5]. Our nyc property tax guide covers the Class 4 application.

For commercial properties, the evidence process is heavier. You'll typically need two to three years of rent rolls, operating expense statements, and a reconciled net operating income calculation. The notice of appeal is still just the door opener, but your evidence prep needs to start the moment you file, not the week before the hearing.

Do you need a lawyer or tax agent to file the notice of appeal?

No. In nearly every U.S. jurisdiction, a property owner can file a notice of appeal and represent themselves at the hearing without any professional help. Boards of equalization and appraisal review boards are built to accommodate pro se (self-represented) filers.

For residential properties, doing it yourself is almost always practical. The form is plain, the evidence is findable (comparable sales are public record in most states), and the hearing is informal compared to a court proceeding.

Professionals add real value in a few spots: large commercial properties where the income approach needs a certified appraisal, properties with odd features that are hard to comp, and cases where the dollar amount at stake justifies the fee. A 10 percent reduction on a $500,000 assessment cuts $50,000 off the assessed value, which might mean $500 to $1,500 a year in tax savings depending on your local rate. Paying a contingency firm 30 to 40 percent of that first-year savings rarely makes sense for a homeowner.

The TaxFightBack DIY appeal kit is built for homeowners who want to keep 100 percent of whatever reduction they win. You don't need any kit to file the notice. The form is free. The process is public.

Frequently asked questions

How long do I have to file a property tax appeal after I get my assessment notice?

It depends on your state, but the common windows are 30 days (Florida, some Georgia counties), 45 days (Georgia standard), and 60 days (California). Texas gives you 30 days from the notice or until May 15, whichever is later. The clock almost always runs from the mailing date of the assessment notice, not the date you received it. Check your county's assessor website or the back of your notice for the exact deadline.

Can I file a property tax appeal without an attorney?

Yes, in every U.S. jurisdiction. Property owners have the right to represent themselves before local boards of equalization and appraisal review boards. For most residential appeals, self-representation is straightforward. You file the notice of appeal form, gather comparable sales from public records, and present your case at an informal hearing. An attorney or certified appraiser is worth considering only for high-value commercial properties where the math justifies the fee.

What is a parcel identification number and where do I find it?

A parcel identification number (PIN, APN, or parcel number) is the unique identifier your county uses to track your property in its records. It appears on your assessment notice, your property tax bill, and usually on your deed. It's typically a 10-to-14 digit number, sometimes formatted with dashes. Always copy it directly from your official document. One wrong digit and you're appealing a different property.

What do I put in the 'reason for appeal' box on the form?

Keep it short. Something like 'Property is overvalued based on recent comparable sales' or 'Assessed value exceeds fair market value' is enough. The form is not the place for your full argument. You present evidence at the hearing. If your state offers an 'unequal appraisal' basis (Texas does under Tax Code Section 41.41), check that box too if your neighbors' similar properties are assessed lower than yours.

Do I have to pay my property tax bill while my appeal is pending?

In most states, yes. Filing an appeal does not defer your payment obligation. You pay the bill at the disputed assessed value, and if you win, the county issues a refund or a credit. Florida requires payment of at least 75 percent of the ad valorem taxes before an appeal can proceed to circuit court (Florida Statutes Section 194.014). Missing the due date can also add penalties and interest that won't be wiped out even if you win.

What if I miss the property tax appeal deadline?

In most cases you lose the right to appeal that year's assessment. Appeal deadlines are generally jurisdictional, meaning the board has no legal authority to hear a late case even if your reason is sympathetic. A few states allow exceptions for documented mail failures or declared disasters. If you just missed the window, contact the board clerk immediately and ask whether any late-filing provision exists. Then prepare for next year's assessment.

Should I attach comparable sales or an appraisal to my notice of appeal?

Generally no. The notice of appeal opens your case; it doesn't present your evidence. Most jurisdictions have a separate evidence submission deadline before the hearing. Attaching a large evidence packet to the initial notice can create procedural problems and clutters the record. Keep your evidence organized separately and submit it on the timeline the board gives you after acknowledging your appeal.

What assessed value should I request on the appeal form?

Request a specific number if you can support it. The best anchor is the price of recent comparable sales of similar homes in your neighborhood, adjusted for differences in size, age, and condition. If three comparables average $280,000 and your assessed value is $340,000, requesting $275,000 to $285,000 is defensible. Avoid an arbitrary low number with no support. Boards that see $1 requests or obviously unsupported figures give them no weight.

Can I appeal if my property tax bill went up but my assessment didn't change?

Usually not through the standard assessment appeal process. If your assessed value stayed the same but your tax bill rose, the change likely came from a mill rate or levy increase by your taxing district, not the assessor. You can't appeal a tax rate through the assessment appeal process. You can only appeal the assessed value. Check your assessment notice first to confirm whether the value itself changed.

What is unequal appraisal and how do I claim it on the form?

Unequal appraisal means your property is assessed at a higher percentage of market value than comparable properties nearby, even if the absolute dollar value is arguably close to market. Texas explicitly recognizes this as a separate appeal basis under Tax Code Section 41.41. Some other states have similar provisions. On the form, check both 'overvalued' and 'unequal appraisal' if both apply. Evidence for unequal appraisal is typically a ratio study comparing your assessed-to-market ratio against neighbors.

How do I file a property tax appeal in a different county from where I live?

You file with the county where the property is located, not where you live. If you own a rental in a different county or state, find that county's assessor or BOE website, get their specific form, and follow their deadline and submission rules. Being out of the area doesn't change the process. Online filing portals make this far easier for remote owners than it was a decade ago.

What happens at the actual appeal hearing after I file my notice?

Most residential hearings are informal, lasting 15 to 30 minutes. You present your evidence (comparable sales, an appraisal, photos showing condition issues), the assessor's representative explains their valuation, and the board asks questions. In some jurisdictions the board decides on the spot; in others you get a written decision by mail weeks later. You don't need to dress or speak like a lawyer. Clear, fact-based presentation of your comparable sales is what wins cases.

Is the notice of appeal the same as the hearing request form?

In most jurisdictions, yes. The notice of appeal both tells the board you're disputing the assessment and triggers the scheduling of your hearing. A handful of states use a two-step process where you first file a protest notice and then separately request a formal hearing if informal resolution fails. Texas uses this model through the Appraisal Review Board. Read your county's instructions to know whether one form or two are required.

Can I withdraw my appeal after filing the notice if I change my mind?

Yes, in almost every jurisdiction. You typically file a written withdrawal with the board before your scheduled hearing date. There's usually no penalty for withdrawing, and in some cases the assessor may have already offered an informal reduction before the hearing that makes withdrawal the right move. If you withdraw after accepting a settlement, make sure the agreement is in writing and specifies the adjusted assessed value before you sign anything.
