Can you appeal property taxes every year on the same house?

Last updated 2026-07-09

Is there a rule against appealing the same property more than once?

No. There is no federal rule, and in the overwhelming majority of states there is no state rule, that stops a homeowner from filing a property tax appeal on the same house year after year. Each assessment year is a new, independent event. If your county reassesses your home every year and sets a value you think is too high, you can challenge that new value every year.

A handful of states reassess on two-year or four-year cycles rather than annually. In those places, you still get one appeal window per assessment cycle. You could still file in back-to-back years if the reassessment year falls that way, but in most of those jurisdictions you cannot appeal a value that has not changed since the last cycle. California is the big exception to the annual-appeal model. Under Proposition 13, assessed value is locked at the purchase price and rises by at most 2 percent per year, so there is rarely a basis to appeal unless you think the purchase-price base was set wrong, or you apply for a temporary "Decline in Value" reduction under Revenue and Taxation Code Section 51 ^[1].

Everywhere else, treat the annual notice of assessment as an annual invitation to check the math and push back if it is wrong.

How often can you actually appeal, state by state?

The answer turns on two things: how often your state reassesses, and how long the appeal window stays open each cycle. The table below covers the most-appealed states.

State	Reassessment cycle	Typical appeal deadline	Repeat annual appeal allowed?
Illinois (Cook County)	Triennial (by township)	30 days after notice mailed	Yes, each reassessment year [2]
Texas	Annual	May 15 or 30 days after notice	Yes, every year [3]
New York City	Annual	March 1 (most classes)	Yes, every year [4]
Georgia	Annual	45 days after notice	Yes, every year [5]
New Jersey	Annual	April 1	Yes, every year
Florida	Annual	25 days after TRIM notice	Yes, every year
California	Annual, but base value capped	Sept 15 (most counties)	Only if decline-in-value applies [1]
Minnesota	Annual	April 30 (Tax Court petition)	Yes, every year [8]
Pennsylvania	Annual (varies by county)	Varies, often Aug 1	Yes, every year
Missouri	Odd years only	July 10 (informal)	Yes, each odd year [12]

Cook County, Illinois is worth flagging. The county is split into thirds and reassessed on a rolling three-year schedule. If your township was reassessed in 2023, your next reassessment year is 2026, and you would appeal again in 2026 ^[2]. Texas runs the opposite way. Every property gets a new appraisal every year, and you can protest every single one without any limit on how many times you have done it before ^[3].

St. Louis County runs on Missouri's odd-year schedule. For how that plays out at the local level, see our guide to st louis county personal property tax.

Does winning one year hurt your chances next year?

Not legally, no. A win in Year 1 does not bind the assessor in Year 2. They can, and sometimes do, reassess the property upward again the following year. There is no double-jeopardy protection that stops the assessor from re-raising your value.

What a prior win does give you is a useful data point for the next round. Say you got your value cut from $400,000 to $360,000 in Year 1, and the assessor comes back in Year 2 at $395,000. You can walk into the hearing with the prior ruling in hand. Many appeal boards and hearing officers give informal weight to a recent reduction, though the law does not require it. Keep the written decision or settlement letter and bring it to the next hearing.

The real risk runs the other direction. If you appealed and lost, and nothing about the market has changed, you are unlikely to win again on the same evidence. Do not re-file just to re-file. Re-file when you have something new: a recent sale of a comparable home below your assessed value, a licensed appraisal, or documented physical damage the assessor missed.

What is the deadline to appeal your property taxes each year?

Deadlines are hard stops. Miss one and you are locked out for that entire assessment year. The deadline does not stretch because you missed it last year, or because you are waiting on more information.

Deadlines vary enormously. Texas sets the protest deadline at May 15 or 30 days after the notice of appraised value is mailed, whichever is later ^[3]. New York City Class 1 properties (one-to-three family homes) must file a complaint by March 1 each year ^[4]. Georgia gives you 45 days from the date the assessment notice is mailed, a deadline that can land anywhere from late spring to midsummer depending on when your county sends notices ^[5]. In many counties the window is so short that a homeowner who gets the notice on a Friday and waits until Monday to think about it has already burned part of it.

Write the appeal deadline on your calendar the day you receive your assessment notice. In ink. Do not assume it matches last year. Statutes change, counties change their mailing schedules, and a few states (New Jersey, for one) have seen deadline shifts after legislative sessions.

What evidence do you need to win a repeat appeal?

The evidence standard does not soften because you have appealed before. Every year, the burden is on you (in most states) to show the assessed value exceeds market value. Three kinds of evidence actually move appeal boards: recent comparable sales ("comps"), a licensed fee appraisal, and documented physical condition issues (defects, deterioration, or facts the assessor's record got wrong).

Comps are the workhorse. You want three to five sales of properties genuinely similar to yours, ideally within the past 6 to 12 months and within a half mile in urban areas or a reasonable radius in rural ones. Pull them from your county's own sales data, from the MLS through a willing agent, or from a state land records database. The closer in time and geography, the better.

A licensed appraisal is the strongest single piece of evidence, but it costs money, typically $300 to $600 for a single-family home depending on your market. If the potential tax savings justify it, it is often the right call. Say your assessment is $20,000 over market. Your tax savings might run $200 to $500 per year depending on your effective rate, which means a $400 appraisal pays for itself in one to two years and then keeps saving you money every year you hold the lower value.

Condition issues are underused. A roof that needs replacing, a foundation with documented cracks, an HVAC system at end of life, those are all value-reducing factors. Bring photos, contractor estimates, or repair invoices. Most assessors run mass-appraisal models that cannot see inside your house, and a structural problem can genuinely shift the value.

What is the success rate for property tax appeals?

Nobody has clean national data on this. The closest public figures come from individual jurisdictions that publish their own statistics.

In Cook County, Illinois, Assessor's Office data shows roughly 50 to 60 percent of residential appeals produce some reduction, though the average size varies by year and township ^[2]. Lincoln Institute of Land Policy research found that in the jurisdictions studied, over-assessment rates for lower-value homes ran materially higher than for higher-value homes, a structural bias in mass appraisal that informed appeals can correct ^[6]. The National Tax Lien Association does not publish appeal success data for residential properties.

The honest answer: success rates track almost entirely with whether the assessed value is actually above market value. File with real comparable sales showing a gap, and the win rate is high. File because you are angry about rising taxes but have no evidence the value is wrong, and the win rate is low. These two groups average out to whatever number a jurisdiction reports, which is why the aggregate tells you less than you would hope.

One clean figure from the Lincoln Institute: in some urban markets, homes in the bottom quintile were assessed at effective rates 1.5 times higher than top-quintile homes, meaning lower-value homes were proportionally overtaxed ^[6]. If your home sits in that range, that is a real reason to appeal every single year.

Should you appeal every year, or only when your value jumps?

Here is my actual opinion: check the math every year, but only file when the numbers justify it.

The check takes maybe 20 minutes. Pull up your county assessor's website, find three or four recent comparable sales in your neighborhood, and see if your assessed value holds up against those sales. If it does, skip the appeal and move on. If the gap is 5 percent or more, and the dollar savings would be meaningful, file.

The case for checking every single year, even in a flat market, is that assessors make mistakes. A neighbor's sale at a high price can pull your value up through the mass-appraisal algorithm even when your house has characteristics that don't support that price. A new addition or renovation getting double-counted happens more than you would think. Square footage, bedroom count, or lot size errors in the assessor's records are real, and they poison every year's assessment until you catch them.

Montgomery County, Maryland, which does annual assessments on a staggered three-year notice cycle, shows why. You can go years between formal notices but should still check the value each year. See our montgomery county property tax guide for how that cycle works.

Can a failed appeal raise your taxes?

This is the fear that keeps people from filing, and it deserves a straight answer.

In most states, it comes down to whether your jurisdiction lets the assessor raise your value as a result of your appeal. A handful of states and localities have cross-appeal or counter-assessment provisions. New Jersey is the clearest example: a municipality can challenge your assessment if it thinks the value is too low. If you appeal in New Jersey and a comparable sale shows your home is worth significantly more than assessed, the municipality can use your own appeal to push the value up ^[7]. This is rare in practice, but it is real, and it is the most common way an appeal backfires.

In Texas, Georgia, Illinois, New York, and most other states, the assessor cannot raise your value as a direct result of your appeal. They can raise you at the next assessment cycle, but that would have happened anyway. The appeal itself does not trigger the increase.

If you are in New Jersey or another jurisdiction with cross-appeal exposure, run the math before filing. If your assessed value already sits below market, you may want to leave it alone.

What happens to your appeal if you sell the house?

A pending appeal generally does not transfer to a buyer on its own. In most states, when you sell, the appeal either lapses or you assign it to the buyer in writing as part of the sale contract. If you filed and then sold before the hearing, you typically need to either withdraw the appeal or work out with your buyer who gets any resulting refund.

This matters because many residential appeals take 6 to 18 months to resolve, especially if you push past the informal hearing to a formal board or tax court. Buy a house in the spring, file an appeal in the summer, sell the following winter, and the appeal might still be open at closing.

Disclose any pending appeal to your real estate agent and have your attorney address it in the sale contract. The refund, if you win, is real money, and leaving it unaddressed creates confusion that can delay closing.

For LA County homeowners in a sale, the timing of the annual assessment and appeal cycle intersects with California's Prop 13 decline-in-value rules in specific ways. Our la county property tax article covers how that plays out.

How do you file a property tax appeal without a lawyer or contingency firm?

You do not need either. The informal appeal at the local level, which is where most cases settle, is a plain administrative process any homeowner can handle.

The basic sequence: (1) get your assessment notice, (2) note the appeal deadline, (3) pull comparable sales from your county's public records or the MLS, (4) compare those sales to your assessed value per square foot, (5) fill out the appeal form (almost always on your county assessor's or board of review's website), (6) attach your comps and any condition documentation, and (7) show up (or submit remotely where allowed) and walk through your evidence calmly.

The formal levels, board of equalization hearings and tax court, are more involved but still doable without an attorney for single-family residential cases. Tax court has filing fees (usually $25 to $75), and some states want a formal appraisal at that level. Contingency firms typically charge 25 to 40 percent of the first year's savings ^[11]. For a reduction that saves you $600 per year, that is $150 to $240 gone to fees. Over five years at the same reduced value, that money stays in your pocket if you filed yourself.

The TaxFightBack appeal kit is built for exactly this process, with state-specific forms, a comparable sales worksheet, and a step-by-step guide to presenting your case at an informal hearing without a representative.

What if your assessed value did not change but your tax bill went up?

This trips up a lot of homeowners. Your property tax bill is the product of two numbers: your assessed value and the tax rate ("mill rate" or "levy rate"). An appeal can only touch the assessed value. It cannot touch the tax rate, which your local government sets through a separate budget process.

So if your assessed value stayed flat at $300,000 but your county raised the mill rate from 1.2 to 1.4 percent, your bill climbs from $3,600 to $4,200, and an appeal does nothing to fix that. The only way to fight a rate increase is political: attending budget hearings, contacting your county commissioners, or voting.

If your assessment went up and your tax rate went up too, you have two problems, and an appeal only solves one. Still worth filing if the assessed value is above market, but calibrate your expectations. Even a win might not bring the bill back to last year's number.

Property tax bills also carry special assessments and fees (stormwater, fire district, lighting) that have nothing to do with the assessed-value appeal. Read your bill line by line so you know what is actually driving the increase before you decide to appeal.

Frequently asked questions

Can you appeal property taxes every year in Texas?

Yes. Texas Tax Code Section 41.44 lets a property owner file a protest every single year, and the Appraisal Review Board hears it fresh each time. There is no limit on how many years in a row you can protest. The deadline is May 15 or 30 days after the appraisal notice is mailed, whichever is later. Homeowners who protest consistently tend to report cumulative savings well above a one-time appeal.

Does winning a property tax appeal affect future assessments?

Not legally, but practically, yes. A win creates a documented market-value finding that some assessors and hearing officers treat as informal precedent the following year. The assessor is not legally bound by your prior reduction. They can re-raise your value at the next reassessment cycle. Keep the written decision from every successful appeal and bring it to any future hearing as supporting evidence.

Can your taxes go up because you appealed?

In most states, no. Filing an appeal does not trigger a review of whether your value should be higher. New Jersey is the main exception: municipalities can cross-appeal if comparable sales suggest your property is under-assessed. If you are in New Jersey and your assessed value already sits below market, think carefully before filing. In Texas, Georgia, Illinois, Florida, and most other states, there is no cross-appeal risk on residential property.

What is the deadline to appeal property taxes in most states?

It varies sharply. Texas: May 15 or 30 days after notice, whichever is later. New York City: March 1 for most residential classes. Georgia: 45 days from the assessment notice date. New Jersey: April 1. Florida: 25 days after the TRIM notice, usually in mid-September. Missing the deadline by even one day kills your appeal for that year. Check your specific county assessor's website for the exact current date.

How long does a property tax appeal take?

Informal hearings at the county level typically resolve in two to six months. Escalate to a formal board of equalization or state appeal board and add another three to nine months. Tax court cases can run one to three years. In Cook County, Illinois, the full path from filing to a board of review decision has historically taken six to twelve months. Most homeowners settle at the informal level, which is faster and needs no attorney.

Can you appeal if your assessment stayed the same as last year?

In most states, yes. As long as you believe the current assessed value exceeds market value, you can appeal, even if the number did not change from the prior year. The test is whether the value is correct today, not whether it moved. An unchanged assessment that was already too high is still appealable. Pull current comparable sales to see if a gap exists before you file.

Do you need a lawyer to appeal property taxes?

No, especially at the informal hearing level. Most states let any property owner represent themselves before the local board of review or appraisal review board. Lawyers and contingency firms earn their keep on high-value commercial properties or cases headed to tax court. For a typical single-family home, the informal hearing is manageable without professional help, and doing it yourself means you keep 100 percent of any reduction.

How much can you save by appealing your property taxes?

It depends entirely on how far your assessed value exceeds market value and what your local tax rate is. A $30,000 reduction at a 1.5 percent effective rate saves $450 per year. Over five years, that is $2,250. The Lincoln Institute of Land Policy found systematic over-assessment of lower-value homes in multiple U.S. cities, so the opportunity is real and recurring. There is no guaranteed savings; check the comparable sales in your specific neighborhood.

What evidence is strongest for a property tax appeal?

Recent comparable sales (within 6 to 12 months, geographically close, genuinely similar homes) are the strongest evidence at an informal hearing. A licensed appraisal is the strongest single document but costs $300 to $600. Documented physical defects, structural issues, or record errors (wrong square footage, wrong bedroom count) are also very effective because they directly challenge the data the mass-appraisal model used. Bring photos and written estimates for any defect you claim.

Can you appeal a property tax assessment after the deadline?

Almost never. The deadline is a statutory hard stop in virtually every state. Courts have repeatedly upheld late-filing rejections even when the homeowner had a strong case on the merits. A few states allow a late appeal in cases of documented hardship or when the assessment notice was never received, but these exceptions are narrow and rarely granted. The only safe approach is to file on time.

What is the difference between a property tax appeal and an exemption application?

An appeal challenges the assessed value of your property, arguing it is set too high relative to market value. An exemption (homestead, senior, veteran, disability) cuts the taxable value or the tax owed by a fixed amount or percentage, regardless of what the market says the property is worth. You can pursue both in the same year. They run through different offices: the appeal goes to a board of review or appraisal review board, while exemption applications go directly to the assessor.

If you get a reduction, does it apply automatically next year?

No. A successful appeal locks in the reduced value for the current tax year only. The assessor reassesses the property in the next cycle and may raise the value again. You have to check the new assessment when it arrives and, if it is high again, file a new appeal. This is exactly why the annual review habit pays off: last year's win does not protect you from this year's over-assessment.

How do property tax appeals work in New York City?

NYC has a four-class property tax system. Most homeowners (Class 1, one-to-three family homes) file a complaint with the Tax Commission by March 1 each year. The Tax Commission reviews the complaint and either offers a settlement or schedules a hearing. If you are unsatisfied, you can proceed to Small Claims Assessment Review (SCAR), which has a $30 filing fee. You can file with the Tax Commission every year. See our nyc property tax guide for full details.
