How long does a property tax appeal take from filing to decision

Last updated 2026-07-11

What's the short answer on appeal timelines?

The range is enormous, and that's not a dodge. A quick informal review by your assessor's office can close in three to six weeks. A formal hearing before a state board of equalization, if you're in a congested jurisdiction, can drag past 24 months. The difference isn't random. It comes down to four things: which level of appeal you file at, how backed-up your county's docket is, whether you submit a complete package the first time, and whether you settle early or push to a formal hearing.

The median time from filing to decision, in counties that publish this data, lands somewhere around 4 to 6 months at the informal and local board level ^[1]. State-level appeals take longer. Litigation in tax court takes longer still. Most homeowners never go past the first or second rung.

Here's the practical frame. Budget 90 days for the optimistic path, 12 months for the realistic path, and 24-plus months only if you're fighting a large commercial assessment or live somewhere with a notoriously slow board.

What are the stages of a property tax appeal, and how long does each one take?

Property tax appeals move through up to four distinct stages, and you can stop at any rung once you get a number you can live with.

Stage 1: Informal review with the assessor (2 to 8 weeks) This is the fastest and cheapest option. You contact the assessor's office, point out errors or bring comparable sales, and a staff appraiser looks at your file. Many counties resolve 40 to 60 percent of appeals here without any formal hearing ^[2]. The downside is you have no subpoena power and no independent decisionmaker. If the assessor says no, you move on.

Stage 2: Local board of review or equalization (1 to 6 months) This is the formal step most homeowners end up at. You file a petition, get a hearing date, present your evidence, and a panel of appointed board members rules. In smaller counties with light dockets, hearings get scheduled within 30 to 60 days of filing. In Cook County, Illinois, the Board of Review regularly runs dockets 6 to 12 months past filing ^[3]. In New York City, the Tax Commission's annual docket regularly carries appeals filed in March through decisions issued the following year or later ^[4].

Stage 3: State board of equalization or administrative tribunal (6 to 18 months) If you lose at the local level or want a second bite, most states have a state-level board or administrative law court. California's Assessment Appeals Boards (one per county) are legally required to hold hearings within two years of a timely filing, and many finish in 9 to 14 months ^[5]. Texas's Appraisal Review Boards aim to hold hearings within the tax year, but some ARB dockets in Harris and Tarrant counties run 4 to 6 months from filing ^[6].

Stage 4: Judicial appeal (1 to 4 years) Taking your case to state tax court or district court is slow and expensive. This path makes sense only when the dollar amount justifies attorney fees and you've used up your administrative remedies. Most homeowners never need it.

How does your county's backlog affect the timeline?

Backlog is the single biggest variable, and it's almost entirely outside your control. Boards of review are staffed and funded by local governments that often haven't scaled resources to match rising assessment volumes after hot real estate markets.

The table below shows published or reported timeline data for several large counties ^[3][4][7][8].

County / Jurisdiction	Stage	Typical wait after filing
Cook County, IL (Board of Review)	Formal board	6 to 12 months
New York City (Tax Commission)	Formal board	12 to 24+ months
Los Angeles County, CA (AAB)	Formal board	6 to 24 months
Harris County, TX (ARB)	Formal board	2 to 5 months
Hennepin County, MN (Tax Court)	Judicial	12 to 36 months
Bexar County, TX (ARB)	Formal board	2 to 4 months
Montgomery County, MD (SDAT appeal)	State admin	6 to 12 months

If you're in Los Angeles County or NYC, the long tail is real. The Los Angeles County Assessment Appeals Board has published reports showing multi-year backlogs during peak filing periods ^[7]. The Cook County Board of Review processes hundreds of thousands of appeals a year and has openly acknowledged docket congestion ^[3].

Smaller, lower-volume counties often move faster. Don't assume your situation mirrors what you read about the big metros.

Does filing earlier in the appeal window make the process faster?

Generally, yes. Filing early in the appeal window pushes you toward the front of the docket in most jurisdictions. Boards and review panels typically schedule hearings in rough order of receipt. Filing on day one of the window versus day 29 of a 30-day window can mean months of difference in your hearing date.

There's a second reason to file early. It gives you time to gather strong comparable sales evidence without rushing. A weak or incomplete filing often triggers requests for more information, which adds weeks.

One nuance: in Texas, the appraisal review board season runs from roughly May through July for most counties, and your hearing is scheduled within that window regardless of when exactly you filed your protest before the May 15 deadline ^[6]. So the gap between early and late filing matters less there than in states where hearings are scheduled year-round.

In California, the application window for most counties is July 2 through November 30, and Assessment Appeals Boards schedule hearings roughly in the order applications come in ^[5]. Filing in July versus November can realistically shift your hearing date by 6 months or more.

What can slow down your appeal after you've filed?

Several things can add months to your wait, most of them preventable.

Incomplete applications. If your county's petition form requires a parcel number, legal description, or statement of the value you believe is correct, and you leave any of it blank, the clerk sends it back. That clock restart can cost you 30 to 60 days.

Requesting a continuance. If you ask to reschedule your hearing date, most boards grant it once, but you move to the back of the queue. In a busy county that's a real penalty.

Stipulation negotiations. In some counties, notably Cook County, Illinois, attorneys often negotiate stipulated reductions with the assessor's office before the formal hearing. That negotiation can save you hearing prep time but adds its own back-and-forth delay.

Appeals of the wrong thing. In states with a split assessment system (like Maryland, where the State Department of Assessments and Taxation sets values on a three-year cycle), filing at the wrong agency or missing the specific appeal type wastes months before you even get redirected ^[8].

Staffing gaps on the board. Boards of equalization are often understaffed and lean on part-time or volunteer members in smaller counties. When members leave mid-year, hearing schedules slip.

The best move is to treat your filing packet like a court filing: complete, labeled, organized, with evidence attached from day one.

Can you get a faster decision through an informal settlement?

Yes, and for most homeowners this is the fastest realistic outcome. Most assessors and boards of review have some form of pre-hearing settlement process. In Cook County, pre-hearing evidence review by the Board of Review's staff is common. In Texas, the appraisal district can make you a settlement offer before your ARB hearing, and you can accept or reject it ^[6].

Settlements happen faster for a simple reason: they skip the formal hearing slot. If the assessor's staff appraiser reviews your comps and agrees your home was over-assessed by 8 percent, they can recommend a reduction the board approves administratively, often in 2 to 4 weeks. No scheduled hearing needed.

The tradeoff is that you're negotiating without the procedural protections of a formal hearing. You also generally can't appeal a settlement to the next level. So if the informal offer is 4 percent off and you believe 18 percent is correct, it may make sense to decline and take your chances at the formal hearing.

The TaxFightBack DIY appeal kit walks through how to structure your comparable sales evidence so it's strong enough to support a settlement offer, without paying a contingency firm 30 to 50 percent of your savings.

One more thing: settlements on commercial properties in some states require board approval even when both parties agree, which adds a procedural step and sometimes a waiting period.

What happens to your tax bill while you're waiting for a decision?

This part surprises a lot of people. You still owe taxes based on the disputed assessment while your appeal is pending. You do not get to withhold payment while you wait. Missing your tax due date triggers penalties and interest regardless of any pending appeal.

What actually happens depends on your state.

Refund states. In most states, you pay the full tax bill as assessed, and if you win, the county refunds the overpayment with or without interest. California refunds overpaid taxes with interest at 3 percent per year under Revenue and Taxation Code Section 5096 ^[5]. Texas issues refunds for successful protests typically within 60 to 90 days of the ARB order.

Escrow or payment-under-protest states. Some states let you (or require you to) pay the undisputed portion and formally tender the disputed portion under protest, which reserves your rights. Mississippi, for example, has a payment-under-protest mechanism under Miss. Code Ann. Section 27-35-95 ^[9].

Abatement states. A handful of jurisdictions can suspend billing on the disputed portion while an appeal is pending, but this is the exception, not the rule, and usually requires a court order.

The bottom line: pay on time, every time, while you appeal. A refund is better than a penalty. Keep a copy of every payment as proof for the refund calculation.

For specifics on payment portals and due dates, check resources like online tax payment for property or your county assessor's site directly.

How do timelines differ between residential and commercial property appeals?

Commercial appeals take longer. Full stop.

The evidence is more complex (income approach valuations, cap rate disputes, lease abstracts), the dollar amounts are higher, and both sides are more likely to have attorneys who negotiate before and during the hearing. A major commercial appeal in a large county can easily run 2 to 4 years from filing to final resolution once you fold in a possible judicial appeal.

Residential appeals are usually simpler. You're comparing your assessed value to recent sales of similar homes in the same neighborhood. That evidence is faster to gather and faster to evaluate. Most residential decisions at the local board level come within 6 to 9 months of filing in a typical county.

One structural difference: commercial property owners in many states have separate or additional appeal tracks. New York City's Tax Commission, for instance, runs distinct procedures and timelines for different property classes ^[4]. Hennepin County, Minnesota handles many commercial disputes through the Minnesota Tax Court, with timelines that routinely run 2 to 3 years ^[7]. The Hennepin County property tax system is a useful example of how complex multi-step commercial timelines work.

If you own a commercial property under around $500,000 in assessed value, the timeline and process often mirror the residential path closely enough that self-representation is viable.

What does the decision actually look like, and when do savings show up on your bill?

After the hearing, you typically get a written decision by mail within 2 to 8 weeks. Some jurisdictions (California's Assessment Appeals Boards, for instance) require written findings within a set timeframe after the hearing closes ^[5]. Others just mail you a form with a number.

The decision states the new assessed value, if any change was granted. It does not automatically adjust your tax bill. That takes the assessor updating their records and sending the corrected data to the tax collector's office, which then issues a corrected bill or refund.

That administrative processing step takes 4 to 12 weeks in most counties after the decision date. So your actual savings show up 1 to 3 months after you get the decision. If your county already billed for the year and you paid in full, expect a refund check (or credit against next year's bill, depending on local practice) rather than an adjusted statement.

In states with multi-year assessment cycles (Maryland, for example, reassesses residential properties on a three-year schedule ^[8]), a successful appeal locks in a lower base value for the rest of that cycle, meaning you get savings for 2 to 3 years without re-filing every year. That's a real multiplier on whatever effort you put into the appeal.

For Gwinnett County, Georgia taxpayers, decisions from the Board of Equalization are issued within a timeline set by Georgia Code, and the assessor's office then has a specific window to implement the change (see Gwinnett County tax assessor for the county-specific process).

Is there anything that can reset or extend the timeline you didn't expect?

A few scenarios genuinely catch people off guard.

Assessment corrections mid-appeal. If the assessor voluntarily corrects the assessment after you file but before your hearing (sometimes they do this when they see your comparable sales), the correction may moot your appeal or require you to re-file for a further reduction. Confirm with the clerk whether the original appeal stays active.

The board reschedules your hearing. Boards reschedule for quorum issues, staffing, or packed dockets. This happens more than people expect and can add 60 to 120 days to your wait with no action on your part.

You move to judicial appeal. If you lose at the board level and file in state tax court, you're entering a separate proceeding with its own docket, discovery rules, and timeline. Plan on 1 to 3 more years.

Ownership transfer. Selling the property mid-appeal can complicate who has standing to collect the refund. In some states, the right to appeal and any refund transfers with the deed; in others, it stays with the original owner. Check your state's rules before closing on a sale.

Disaster or mass-appraisal events. After a natural disaster or a large-scale revaluation fight, some counties open emergency appeal windows or face filing spikes that push wait times well past normal.

If your appeal is pending and you're wondering whether the Bexar County tax assessor or St. Louis County personal property tax processes have county-specific wrinkles, the assessor's office published timelines (and the state statutes behind them) are your most reliable reference.

How can you track your appeal status and know where you stand?

Most large counties now have online portals where you can check your appeal's status. Cook County's Board of Review has a public case lookup. Los Angeles County's Assessment Appeals Board publishes scheduled hearing calendars. Texas appraisal districts post protest hearing schedules online. If your county has no public portal, a phone call to the clerk of the board is entirely appropriate every 60 days or so.

Keep careful records of everything you file and every communication you get. That means dated copies of your petition, any evidence submitted, any correspondence from the board, and any offers made during informal review. If the board later claims it never got your evidence, your dated copies are your only recourse.

Build a simple tracking document: date filed, deadline for the board to schedule a hearing under your state's statute, hearing date if assigned, and follow-up dates. Many states have statutory deadlines by which boards must act. California's two-year rule under Revenue and Taxation Code Section 1604 is one example ^[5]. If a board misses a statutory deadline, you may be entitled to automatic relief or an expedited process, but you won't know that deadline is coming unless you're tracking it.

The TaxFightBack appeal kit includes a tracking checklist built around common state procedural rules, so you know when to follow up and when a delay is actually a violation of your rights.

Frequently asked questions

How long does a property tax appeal take in Texas?

Texas Appraisal Review Board hearings are generally held between May and July each tax year, so if you file before the May 15 deadline, your hearing usually happens within 1 to 4 months. The ARB has to hear and decide protests before the appraisal roll is certified, typically by late July. Large counties like Harris and Tarrant can run closer to 4 to 6 months. Refunds from successful protests typically arrive within 60 to 90 days of the ARB order.

How long does a property tax appeal take in California?

California Assessment Appeals Boards have up to two years from the filing date to hold a hearing under Revenue and Taxation Code Section 1604. In practice, many counties finish hearings in 9 to 18 months. Los Angeles County has historically run longer due to high filing volume. Filing early in the July 2 to November 30 window improves your position in the scheduling queue. After the hearing, written decisions typically issue within a few weeks.

How long does a Cook County property tax appeal take?

Cook County, Illinois has a two-stage system: the Assessor's office for informal review, then the Board of Review for a formal hearing. The Board of Review processes appeals by township on a rotating annual schedule. From filing to decision, expect 6 to 12 months at the Board of Review level. The Illinois Property Tax Appeal Board (PTAB), the next level up, can take another 1 to 3 years because of its statewide docket.

Will I still owe property taxes while my appeal is pending?

Yes. Filing an appeal does not suspend your obligation to pay taxes based on the current assessed value. Pay your bill on time to avoid penalties and interest. If you win, the county refunds the overpayment, sometimes with interest. In a few states you can pay under formal protest to preserve rights, but you still have to pay. Missing the due date while waiting for an appeal outcome is a common and costly mistake.

What is the fastest way to resolve a property tax appeal?

Settling informally with the assessor's office is almost always faster than a formal hearing. Bring clear comparable sales showing your home sold or is worth less than the assessed value, submit them with your petition, and ask the appraiser to review before your scheduled hearing date. Many assessors will offer a reduction rather than proceed to a formal hearing. A complete, well-organized evidence packet at filing is the single biggest factor in a quick settlement.

Can my property tax appeal be denied before a hearing?

Yes, though it's relatively uncommon. An appeal can be dismissed before a hearing if it's filed after the deadline, if it lacks a parcel number or legally required information, or if the petition doesn't state a basis for the appeal as required by your county's rules. Some boards also dismiss appeals where the assessed value already equals or exceeds the market value the owner cited. Always confirm your petition was received and deemed complete.

What happens if the board doesn't schedule a hearing within the legally required time?

Most states have statutory timelines for board action. California gives boards two years. If a board misses its statutory deadline, the property owner may be entitled to automatic relief, meaning the assessed value drops to what the owner claimed, or the right to appeal directly to a higher tribunal. You need to track the deadline yourself and formally notify the board in writing if it lapses. Consult your state's revenue or equalization statute for the exact provision.

Does winning an appeal lower my taxes for multiple years?

It depends on your state's assessment cycle. In states with annual reassessment (most of Texas, for example), a successful appeal applies to that tax year only, and the district can reassess upward the next year. In states with multi-year cycles like Maryland's three-year residential cycle, a reduced base value carries forward for the rest of the cycle. California's Proposition 13 limits annual increases, so a successful appeal can have long-lasting effects on your base value.

How long does a New York City property tax appeal take?

New York City property owners file with the NYC Tax Commission between January 15 and March 1 each year. Simple residential cases (one-to-three family homes) can get administrative decisions within a few months. Larger residential and commercial properties often wait 12 to 24 months or longer. The Tax Commission can also settle cases before a formal hearing. If you reject the Tax Commission's determination, you can file in state Supreme Court, which adds years to the timeline.

Do I need a lawyer to appeal, and does hiring one change the timeline?

For most residential homeowners, you do not need a lawyer. Informal reviews and local board hearings are built to be accessible to self-represented owners. Hiring an attorney or contingency firm doesn't typically shorten the timeline. It may give you better access to negotiation channels in some commercial or high-value cases. For straightforward residential appeals, the cost (often 30 to 50 percent of first-year savings for contingency firms) usually exceeds the value of any timeline advantage.

How long does a property tax appeal take in Florida?

Florida homeowners file with the Value Adjustment Board (VAB) by the September 18 deadline (or 25 days after the Notice of Proposed Property Taxes is mailed). VABs must complete hearings by the time the tax roll is certified, which typically means decisions by December or January. Many counties finish hearings within 3 to 5 months of the filing deadline. Special magistrates conduct individual hearings and VABs then ratify decisions.

What's the difference between an informal review and a formal hearing timeline?

An informal review is a conversation with the assessor's staff appraiser. It has no official deadline for resolution, but most wrap up in 2 to 8 weeks simply because there's no scheduling backlog. A formal hearing before a board has a scheduled date on the docket, procedural notice requirements (typically 15 to 30 days advance notice to both parties), and a written decision afterward. Formal hearings take longer because of that scheduling queue, but they give you more procedural rights.

Can I speed up my appeal if I have strong evidence?

Strong evidence can speed up your appeal indirectly. If you submit clear comparable sales showing a significant over-assessment, the assessor's office is more likely to offer a settlement before the formal hearing, cutting months off the timeline. Strong evidence also reduces the chance of continuances or requests for more information from the board. You can't jump the formal hearing queue, but you can avoid adding time through incomplete filings or weak documentation.

What if I miss the property tax appeal deadline?

In almost every jurisdiction, missing the appeal deadline is fatal to your appeal for that tax year. There are narrow exceptions: some states allow late filing if you can prove you didn't receive notice of the assessment, or if there was a clerical error. A few states have a separate track for manifest errors that can be corrected outside the normal appeal window. Outside those narrow exceptions, you wait until the next assessment notice and file promptly then.
