Sample property tax appeal letter you can adapt

Last updated 2026-07-11

What should a property tax appeal letter actually say?

A property tax appeal letter is a written request asking the local board of review, appeals board, or assessment appeals board to lower the assessed value of your property. It is not a complaint. It is a document that says you disagree with one specific number and that you have a factual basis for a different number.

Every letter that works has five parts: your property identification (parcel number and address), the assessed value you are disputing, the value you believe is correct, the evidence behind that value, and a clear request for relief. Drop any one of them and the reviewer can dismiss you on a technicality, or just skim past you.

Keep the tone flat. Assessors read hundreds of these a season. Emotional language wastes space and gives them a reason to stop reading. Stick to numbers, dates, and named sources.

Length barely matters. A one-page letter with three strong comps beats a five-page letter with none. Most people who file these themselves keep the letter to one or two pages and let the attachments carry the weight.

Re: Formal Appeal of Property Tax Assessment Parcel Number: [Your Parcel / APN / Account Number] Property Address: [Address of the Property Being Appealed] Tax Year: [e.g., 2025]

Dear [Board Chair / Chief Assessor / Clerk of the Board]:

I write to formally appeal the assessed value of my property at [address], Parcel No. [number], for the [year] tax year. The [name of assessing body] assigned an assessed value of $[assessed value on your notice]. I believe the correct market value is no more than $[your estimate], and I respectfully request the board reduce the assessment to reflect that figure.

My basis for this request is as follows:

1. COMPARABLE SALES. Three arm's-length sales of properties substantially similar to mine closed within [number] miles of my property in the [number] months before the assessment date. Those sales indicate a market value range of $[low] to $[high]. See Exhibit A.

2. ASSESSMENT RATIO EVIDENCE (if applicable). The [county/district] assessor's own published assessment ratio study for [year] shows a median ratio of [X%] for my property class. Applying that ratio to my assessment produces an effective value of $[calculated figure], which is [amount] above the indicated market range. See Exhibit B.

3. PROPERTY-SPECIFIC CONDITIONS. My property has [list defects: foundation crack, wet basement, non-conforming layout, deferred maintenance, proximity to commercial corridor, etc.] that comparable properties in the assessment record do not share. These conditions reduce market value by an estimated $[amount], based on [source: contractor estimate, prior appraisal, etc.]. See Exhibit C.

I am available for a hearing at the board's convenience. Please confirm receipt of this appeal and advise me of the scheduled hearing date. I can be reached at [phone] or [email].

Respectfully submitted,

[Signature] [Printed Name] [Date]

That is the whole letter. Everything after it is evidence. The letter's only job is to state the disagreement clearly and point the reviewer to the proof.

What comparable sales grid should you attach?

A comparable sales grid is a table that lines your property up against three to five recent sales of similar homes. Most appeals boards expect one, and some require it on their own form. If your board has no form, a plain table works fine.

Here is a format you can use:

Feature	Subject (Your Property)	Comp 1	Comp 2	Comp 3
Address	123 Main St	456 Elm St	789 Oak Ave	321 Pine Rd
Sale Date	N/A (appeal date)	03/15/2024	11/02/2023	07/20/2023
Sale Price	N/A	$285,000	$291,000	$278,500
Style	Ranch	Ranch	Ranch	Ranch
Year Built	1962	1964	1960	1965
Sq Ft (living)	1,420	1,450	1,390	1,410
Lot Size	0.22 ac	0.24 ac	0.21 ac	0.23 ac
Bedrooms/Baths	3/1.5	3/2	3/1.5	3/1
Garage	None	1-car	None	None
Condition	Fair	Good	Good	Average
Adjusted Value	$285,000	+$5k bath adj	See note	See note

Use sales from the past 12 months. Stay within a half-mile to a mile if your market is dense, or within a reasonable boundary if you are rural. Pull the data from your county's public property records, the sale history on Zillow, or the Multiple Listing Service records a title company or agent can print for you.

Don't cherry-pick the lowest sales. The board will spot the $350,000 sale two streets over that you skipped. Name it, and explain why it isn't a good comp (different school district, gut-renovated, half-acre lot against your quarter-acre). Being upfront about the outliers is what makes the rest of your grid believable.

How do deadlines work and where do you find yours?

Property tax appeal deadlines are some of the strictest in local government. Miss yours by a day and you usually have no recourse until the next assessment cycle. There is almost no forgiveness.

Most states set the deadline off the date your assessment notice is mailed or the date the assessment roll is certified, not the date you actually opened the envelope. That gap matters if your mail runs slow, per the Lincoln Institute of Land Policy's work on property tax administration.

Deadlines swing hard by state and often by county. The table below shows ranges from a handful of high-population states. Always check your own county's current rules against these.

State	Typical Appeal Window	Deadline Trigger	Official Source
California	60 days from notice	Date notice mailed	County Assessment Appeals Board
Texas	May 15 or 30 days from notice, whichever is later	Date notice mailed	Texas Tax Code § 41.44
Illinois	30 days from publication of assessment list	Publication date	35 ILCS 200/16-55
New York	Typically March 1 (varies by jurisdiction)	Fixed calendar date	RPTL § 524
Florida	25 days from TRIM notice mailing	Date of TRIM notice	F.S. § 194.011
Georgia	45 days from date of assessment notice	Date of notice	O.C.G.A. § 48-5-311
Cook County, IL	30 days from publication (township-specific)	Publication	Cook County Assessor

Florida gives you the shortest window on this list: 25 days from the TRIM notice mailing, under Florida Statutes § 194.011. Texas gives you the longest at up to 90 days. That is more than a threefold spread between two big states, which is why you never assume your neighbor's deadline is yours.

If you live in one of the high-tax counties we cover in depth, check the specific calendar in our guides to Cook County tax assessor tax bills, Los Angeles County property tax, or Bexar County. Each jurisdiction publishes its own dates.

The safest move: find the mailing date on your notice, count the days on a paper calendar instead of in your head, give yourself a three-day buffer, and file early.

What evidence actually wins a property tax appeal?

Comparable sales are the most persuasive evidence in most jurisdictions, period. The Appraisal Institute's The Appraisal of Real Estate treats the sales comparison approach as the primary method for valuing residential property, and appeal boards follow the same logic. Show three recent, nearby sales of genuinely similar homes below your assessed value and you have a real case.

Other evidence can back up the comps or stand in for them.

A recent independent appraisal is the single strongest document you can hand a board. A licensed appraiser's report carries professional weight and is hard to wave off without a counter-appraisal. Appeal appraisals run roughly $300 to $500 for a standard residential property, more in high-cost markets. The math is simple: if the reduction saves you $800 a year, the appraisal pays for itself in year one.

A uniformity argument says the quiet part out loud: even if my value is right, my neighbors' identical homes are assessed lower, so I'm carrying more than my share. That is a valid legal claim in most states. Pull three to five similar neighbors' records from the public database and attach them.

Income approach evidence applies mostly to rentals. Own a small apartment building? Show real rent rolls, vacancy rates, and operating expenses. The International Association of Assessing Officers treats capitalized net operating income as the main value indicator for income property, so that is what a commercial board expects to see.

Photos of defects are cheap and effective. A cracked foundation, a failing roof, a dead HVAC system, water stains on a ceiling: a reviewer can't dismiss what the camera shows. A contractor's written repair estimate turns that photo into a dollar figure.

What loses: how much you paid, what you think the tax rate should be, general anger at city hall. The appeal is about one thing, whether the assessed value matches market value or the legal assessment standard.

Do you need a lawyer or a contingency firm to appeal?

No. Most residential property tax appeals need no lawyer at all. Boards of review and assessment appeals boards are built to hear pro se (self-represented) appeals, and in many places most appeals are filed without any representation.

Contingency firms usually take 25% to 50% of your first year's tax savings. That can pencil out for complex commercial properties where the appraisal and legal work is genuinely technical. For a homeowner whose value is $50,000 too high, handing a firm half your savings for a job you could finish in a weekend is a bad trade.

That is the reason this site exists. The TaxFightBack DIY appeal kit walks you through every form, the comp analysis, and a hearing script so you keep 100% of what you save. This article covers what you need with or without any kit.

One scenario where professional help earns its fee: your state requires a licensed appraiser's report just to trigger a hearing (rare, but real in a few jurisdictions), or your appeal turns on complex valuation like contaminated land, a partial taking, or a commercial property with unusual income.

How do you address the letter and where do you send it?

This varies by state and sometimes by county, so know the exact body that hears your appeal before you mail anything.

Most states run two steps. First, an informal review by the assessor's office. Second, a formal hearing before an independent board (a Board of Review in Illinois, a Value Adjustment Board in Florida, an Assessment Appeals Board in California, a Board of Equalization in several other states). You often have to file at the assessor level first before you can reach the independent board.

Address the letter to the body for the stage you are in. Filing an informal review request? Send it to the county assessor or their appeals division. Filing for a formal hearing? Address it to the clerk of the appeals board. The address is on your assessment notice most of the time. If it isn't, search your county assessor's website for "appeal" or "protest."

For counties we cover in detail, the process and addresses are laid out in our guides to Gwinnett County tax assessor, Montgomery County property tax, and Santa Clara property tax.

Mailing a paper copy? Use certified mail with return receipt. That gives you timestamped proof of filing. Online filing does the same thing through the submission timestamp. Many counties now run portals, so check your assessor or tax collector website first.

What happens after you file: the informal review, the hearing, and negotiation

After you file, the assessor's office usually sends a written acknowledgment and either a decision on the informal review or a hearing date. Turnaround runs anywhere from two weeks to six months depending on the county and its backlog. Texas appraisal districts have to deliver a notice of determination within 45 days of getting a protest, under Texas Tax Code § 41.66. Plenty of other states set no firm timeline at all.

The informal review often hands you a partial cut, or nothing, with no hearing. Take a reduction only if it's meaningful. In most states you can decline and still go to a formal hearing even after an informal offer.

At a formal hearing, you present your evidence, the assessor's rep presents theirs, and the board asks questions. Most residential hearings run 15 to 30 minutes. Bring printed copies of everything for each board member plus one for yourself.

Here is what to say when the assessor's rep drops a comp you've never seen: ask for the address and parcel number, pull it up on your phone, and explain why it isn't comparable (different neighborhood, much larger, recently renovated). You are allowed to rebut their evidence on the spot.

Lose at the board level and most states let you go further, to the state tax tribunal or a state court. That level almost always calls for an attorney or at least a licensed appraiser's report, and the cost-benefit math shifts.

In high-volume counties you can watch comparable cases. Cook County's Board of Review docket is public. In New York, the Small Claims Assessment Review (SCAR) process handles owner-occupied homes for a $30 filing fee with fairly informal procedures, under RPTL § 524.

What mistakes get appeals rejected or ignored?

Missing the deadline is the biggest mistake, and nothing else is close. File early.

The wrong form is second. Some counties require their own petition, and stapling a letter to nothing gets you nowhere. Check whether yours makes you complete a specific petition before your letter counts.

Arguing about your tax bill instead of your assessed value confuses what you're actually appealing. You are not appealing the bill. You are appealing the value. The bill is that value multiplied by the tax rate, and no appeal changes the rate.

Bad comps hurt you. A distressed sale, a foreclosure, a sale between relatives, or a home in a clearly different market is not an arm's-length deal, and the assessor will attack it fast. Pull comps from MLS records or county deed records and confirm each one was a normal transaction.

Vague language sinks a letter. "I think my house is worth less" gives the board nothing. "Three arm's-length sales within 0.5 miles, all comparable in condition and size, closed between June and December 2024 at $278,500 to $291,000, indicating a market value near $285,000 against the assessed value of $340,000" gives them a specific, checkable claim.

Are there different rules for commercial property appeals?

Yes. Commercial appeals use the same procedural steps, but the valuation methods differ a lot. Income-producing properties are valued mainly through the income approach: net operating income divided by a market capitalization rate, per the International Association of Assessing Officers. If the assessor's income assumptions are off (rents too high, vacancy too low, wrong cap rate), that is your argument.

The dollars are bigger, so the case for hiring a commercial appraiser and sometimes a property tax attorney gets stronger. A 5% cut on a $5 million assessment drops $250,000 off the value, which at a typical rate saves somewhere between $2,500 and $12,500 a year depending on your local rate. A commercial appraiser's fee of $2,000 to $5,000 comes back quickly at those numbers.

For commercial owners in major markets, our county guides cover the specifics: NYC property tax, LA County property tax, and Hennepin County property tax.

The letter itself looks like the residential template above. What changes is the exhibits: rent rolls, operating statements, and a cap rate analysis take the place of the comparable sales grid as your main evidence.

How do you find your parcel number and assessment details?

Your parcel number (also called APN, account number, or tax map number, depending on the state) sits on your property tax bill, your assessment notice, and your county's online property search portal. Every county in the country keeps a public database of assessed values. Search for your county assessor's website and find the property or parcel search tool.

The assessment notice that opened your appeal window also shows the prior year's value, the new value, and the filing deadline. Keep it. That notice is Exhibit D in your letter.

Once you have your parcel number, pull your neighbors' assessment records from the same public database. That is how you build a uniformity argument. Most portals let you search by address, so you can grab three to five neighbors' records in under ten minutes.

If you pay your taxes online and want to check the bill against your assessment, our guide to online tax payment for property walks through the line items. The assessed value, the exemptions applied, and the effective rate usually all show up on the payment portal.

What if the assessor denies your appeal: what are your options?

A denial at the informal review stage is not the end. In most states you can still file for a formal hearing before the independent appeals board. A denial at the board level isn't final either, since most states let you escalate to the state tax tribunal, tax court, or circuit court.

The escalation deadlines usually run shorter than the original appeal deadline, so watch them. In Illinois you have 35 days from the board of review decision to file with the Illinois Property Tax Appeal Board (PTAB), under 35 ILCS 200. In New York, the SCAR or tax certiorari deadline is typically within 30 days of the final assessment roll, under RPTL § 524.

At the court level you generally need a licensed appraiser's report to win. Courts check whether the board's decision was backed by evidence; they will not take your word over the assessor's. Budget $500 to $1,500 for a residential appraisal, plus court filing fees that run $100 to $400 in most jurisdictions.

One more path: many states let you refile next year with stronger evidence if your circumstances or the market change. A loss this year does not lock in a bad assessment forever. Reassessments run on a one- to four-year cycle depending on the state, and each new assessment opens a fresh appeal window.

Frequently asked questions

How long should a property tax appeal letter be?

One to two pages is plenty for most residential appeals. The letter states your parcel number, the assessed value you dispute, the value you believe is correct, and a short description of your evidence. The actual proof goes in the attachments. A longer letter does not raise your odds. A short, well-organized letter with strong comparable sales does.

Can I email my property tax appeal letter or does it have to be mailed?

It depends on your county. Many jurisdictions now accept email or portal submissions and prefer them because they create an automatic timestamp. Some still require paper by certified mail or in person. Check your county assessor's website or the instructions on your assessment notice. If you mail it, use certified mail with return receipt so you have proof of the filing date.

What if I missed the property tax appeal deadline?

In most states you have no recourse for the current tax year once the deadline passes. You can still prepare for next year's cycle. Keep your comparable sales evidence, document any property defects, and set a calendar reminder for the day your next assessment notice arrives. A few states allow late filings for documented hardship, but it is uncommon, so verify with your specific county.

Do I need a lawyer to write a property tax appeal letter?

No. Residential appeals boards are built to hear pro se cases, and most homeowners who win never used an attorney. You need clear evidence, specifically comparable sales or an independent appraisal, not legal skill. A lawyer adds cost and rarely adds value for a standard residential appeal. Commercial properties with complex valuation questions are the exception.

What is the success rate of property tax appeals?

Nobody has truly clean national data on this. The National Taxpayers Union Foundation has cited figures suggesting 20% to 40% of homeowners who appeal receive some reduction, but the number swings widely by county and year. In Cook County, Illinois, a large share of appealed residential assessments get reduced through the board of review in a given year. Your odds jump when you attach real comparable sales.

Can I appeal if I just bought the house and the assessed value is higher than what I paid?

Yes, and your purchase price is strong evidence of market value, as long as it was an arm's-length deal between unrelated parties and not a distressed sale. Attach the settlement statement (HUD-1 or Closing Disclosure) as an exhibit. Most assessors have to consider recent sales as evidence of market value, and your own recent sale is the most direct comp you have.

What does 'assessed value' mean and is it the same as market value?

Assessed value is the figure the taxing authority assigns to your property for tax purposes. It may equal market value or it may be a set percentage of it, called the assessment ratio, which varies by state and sometimes by property class. If your state assesses residential property at 80% of market value and your home is worth $300,000, the assessed value should be $240,000. Your appeal targets whichever figure produces your bill.

How many comparable sales do I need to include in my appeal?

Three is the minimum most boards find credible. Five is better. The comps should be arm's-length sales of homes with similar size, age, condition, and location, closed within 12 months of the assessment date. Skip distressed sales, foreclosures, and related-party deals. If comparable sales are genuinely scarce in your area, a licensed appraisal can stand in for them.

Will appealing my property tax assessment hurt me in any way?

No. Filing an appeal cannot raise your assessment in most states. Some states bar the board from lifting your value above the assessor's original figure without giving you specific notice. There is no penalty for filing and losing. The only real cost is the time you spend preparing the case.

What is a notice of assessment and what do I do when I receive one?

A notice of assessment is the document your county sends showing the new assessed value for the upcoming tax year. When it arrives, check the value against recent comparable sales right away. If it looks inflated, count the days to the appeal deadline from the mailing date on the notice. Then gather your comps, complete any required petition form, and submit before the deadline.

Can I appeal based on my neighbors having lower assessments than me?

Yes. This is a uniformity or equity argument. If you can show that neighboring properties with similar characteristics are assessed lower, you are carrying a disproportionate tax burden, which is legally challengeable in most states. Pull your neighbors' assessment records from the public county database, build a simple comparison table, and attach it as an exhibit labeled 'Assessment Uniformity Analysis.'

How do property tax appeals work differently for condos versus single-family homes?

The process is the same, but finding comps is harder because condos share a building. Use comparable condo unit sales in the same building first, then the same complex or neighborhood. Also check whether the assessor used the correct unit square footage and amenities. Condo assessments sometimes pull the wrong unit data from a master record, which is an easy factual error to fix.

Is there a filing fee to appeal my property taxes?

Often yes, but usually small. New York's SCAR process charges a $30 filing fee. California's assessment appeals boards charge fees from $0 to about $65 depending on the county and the assessed value. Some counties charge nothing for an informal review but add a fee for a formal hearing. Check your county's assessor or appeals board website for the current fee schedule before you file.

What happens if my property tax appeal is successful: when does my tax bill change?

Win before the tax bill is issued and the corrected value shows up on that year's bill. Win after you have already paid and most jurisdictions send a refund check or credit the overpayment against your next bill. Refund timelines run from a few weeks to several months. Ask the clerk at your hearing when to expect the adjustment.
