How do I appeal my property taxes if I think they are too high?

Appealing your property taxes usually comes down to proving that your local government’s assessed value of your home is higher than its actual market value , or that there is a factual error in your property's record. Because rules and timelines vary heavily by municipality, you'll want to check your local county or city assessor's office website for exact local protocols.

Here is the step-by-step process to build and file your appeal:

1. Know your deadlines
   This is the most critical step. Assessment notices are usually sent out in the first few months of the year, and you typically only have a short window of 30 to 45 days from the date on the notice to file an appeal. Missing this window usually means you have to wait until the next tax year.
2. Check your property record card
   Contact your local assessor's office or visit their website to pull up your official property record card. Check for factual errors:
   • Incorrect square footage of the home or lot size
   • Wrong number of bedrooms or bathrooms
   • Outdated features (e.g., claiming you have a finished basement or a new roof when you don't)
   • Unreported property damage (from storms, fire, or major deferred maintenance)
3. Compare with your neighbors (comps)
   Look at recent sales of similar homes in your immediate neighborhood (similar size, age, style, and lot size). You want to find recent, verified arm’s-length sales where comparable properties sold for less than your current assessed value. (Note: Online real estate estimate values are generally not accepted by assessment boards as legal proof).
4. Start with an informal review
   Many jurisdictions allow (or prefer) you to call or meet with the assessor's office informally before filing a formal appeal. If you found a clear factual error (like wrong square footage) or an obvious comparable sales discrepancy, an appraiser from the office may agree to adjust it on the spot without a formal hearing.
5. File the formal appeal
   If the informal review doesn't work, submit a formal appeal application through your local assessment appeal board or Board of Equalization and Review . Attach your evidence, which may include:
   • Photos of your home's condition
   • A list of comparable properties and their recent sales prices
   • Contractor estimates for major structural repairs
   • A private, independent professional appraisal (best used for high-value discrepancies)
6. Attend the hearing
   Present your case clearly and objectively. Stick strictly to market data, recent sales, and factual conditions of your home. Do not argue that the overall tax rate is too high or that you personally cannot afford the bill, as assessment boards legally can only rule on whether the valuation is accurate.

If you'd like, tell me:

• What state or county your property is in
• Whether you found a factual error or if your argument is based on comparable sales

I can help you pinpoint your local assessor portal or give you tips on what kind of evidence works best for that area.

If you mean your home’s assessed/appraised value is higher than what you believe it’s worth, you generally appeal the property valuation, not the tax bill itself.

Since you appear to be in Franklin County, Ohio, here’s the process there:

How the appeal works

1. Check your county valuation Look up your property through the auditor.franklincountyohio.gov and see the Auditor's current appraised/market value.
2. Gather evidence showing a lower value Strong evidence can include:

• A recent purchase of the property for less than the Auditor's valuation
• A professional appraisal
• Recent sales of comparable homes nearby
• Evidence of significant defects or needed repairs
• Incorrect property characteristics in the county's records

Franklin County specifically says recent appraisals and comparable sales can be presented to the Board of Revision. Franklin County Auditor Franklin County Auditor 3. File a DTE 1 complaint with the Board of Revision This is the formal mechanism for challenging the Auditor's valuation. You state what you believe the property's full market value should be and provide your supporting evidence. Franklin County Auditor 4. Attend the hearing or participate in mediation The Board of Revision can hold a hearing where you present your evidence. Franklin County also has a mediation process that may resolve the dispute without a full hearing. Franklin County Auditor Franklin County Auditor 5. If you lose, you can appeal again A Board of Revision decision can generally be appealed to the Ohio Board of Tax Appeals or the Court of Common Pleas within 30 days after the decision is mailed.

Important timing for you

The 2025 Franklin County Board of Revision filing period is closed; its deadline was March 31, 2026. Franklin County says the next BOR filing season will reopen later in 2026.

However, Franklin County is currently conducting its 2026 property-value update, and the Auditor says owners with questions about their 2026 value can request a Property Value Review through its Know Your Home Value site.

One important distinction

If your complaint is essentially “my taxes went up because my property's value went up,” the BOR is the right avenue. But if you think you qualify for something like the homestead exemption or owner-occupied reduction, that's a different process. Franklin County has separate tax-reduction programs for those situations.

If you give me your county, your property's current assessed/appraised value, and roughly what you think it's actually worth, I can walk you through how much of a reduction you'd have a reasonable case for and what evidence would be strongest.

Property-tax appeals are handled by the local jurisdiction, and the deadlines and evidence requirements vary considerably.

What city/county and state is the property in? For example, “Arlington County, Virginia” or “Montgomery County, Maryland.”

Once you give me the location, I can walk you through the exact appeal deadline, where to file, what evidence to submit, and how to make the strongest case that the assessment is too high.

Appealing your property taxes can be a great way to lower your bill if your home's assessed value is higher than its actual market value.

Here is a step-by-step guide to navigating the appeal process:

1. Review your assessment notice
   Check your recent property tax assessment notice for accuracy. Look at the assessed value of your home and the deadline to file an appeal, as these windows are usually short (often just 30 to 60 days after the notice is mailed).
2. Gather evidence of market value
   Pull together data showing what your property is actually worth. Look for recent sales of comparable homes ("comps") in your immediate neighborhood that sold around the assessment date. You can check sites like Zillow or Redfin or request recent sales data from a local real estate agent. Additionally, check your property record card from the assessor's office for factual errors (e.g., incorrect square footage, wrong number of bedrooms/bathrooms).
3. File the formal appeal
   Contact your local tax assessor's office or local board of equalization/review to get the required appeal application form . Fill it out completely and submit it along with your supporting evidence before the strict deadline passes.
4. Prepare for an informal review
   Many jurisdictions schedule an informal meeting with an appraiser from the assessor's office before a formal hearing. Present your comps and corrections calmly; if they agree the value was inflated, you can settle and lower your taxes without a formal hearing.
5. Present your case at the formal hearing
   If the informal review doesn't work, attend your scheduled hearing before the local assessment appeals board. Bring multiple physical copies of your evidence (comps, photos, correction notes) and keep your presentation focused strictly on market value or factual errors , rather than complaining that taxes are generally too high.

If you'd like, let me know:

• Your state or county
• Whether you've already received your assessment notice

I can help you look up specific deadlines or local appeal forms for your area.

Appealing your property taxes can be a great way to lower your bill if your assessment is unfair or higher than market value. The process varies slightly by location, but the core steps remain consistent across most jurisdictions.

Step-by-Step Appeal Process

1. Review your assessment notice : Check the assessed value of your property and look closely at the deadline to file an appeal. Assessment appeal windows are often very short—sometimes just 30 to 60 days after the notice is mailed.
2. Gather evidence of over-assessment : Collect data to prove your home's value is lower than what the county claims. Strong evidence includes:
   • Recent comparable sales ("comps") : Look for recently sold homes in your immediate neighborhood that are similar in size, age, style, and condition.
   • An independent appraisal : Hiring a licensed appraiser provides an authoritative valuation.
   • Property record errors : Check your local assessor's database for mistakes (e.g., listing a finished basement when yours is unfinished, or overstating the number of bathrooms or square footage).
3. Contact your local assessor informally : Before filing a formal appeal, call or visit your local tax assessor or property appraiser's office. Sometimes, a clerical error or misunderstood fact can be corrected informally without a formal hearing.
4. File the formal appeal application : If the informal review doesn't work, obtain the official appeal form from your local county or municipal tax office, fill it out completely, attach your evidence, and submit it before the strict deadline.
5. Prepare for and attend the hearing : You will likely be scheduled for a hearing before a local board of equalization, tax tribunal, or assessment appeals board.
   • Bring multiple copies of your evidence (comps, photos, paperwork).
   • Keep your presentation focused strictly on market value or assessment equity (how your home is taxed compared to similar neighboring homes), rather than complaining about high tax rates or government spending.

If you think your property taxes are too high, the first step is usually to challenge the property’s assessed value (the value used to calculate taxes), not the tax rate itself. The process depends on your state and county. Since you appear to be in Tiffin, Ohio (Seneca County), the process is through the Seneca County Board of Revision.

How to appeal in Seneca County, Ohio

1. Check your property’s valuation

   • Review your county property record and the auditor’s assessed/market value.
   • Look for errors such as incorrect square footage, wrong property features, or a value that does not reflect the property’s actual market value.

2. Gather evidence Strong evidence can include:

   • Recent sales of similar homes (“comparables”)
   • A professional appraisal
   • Photos or documentation showing issues that reduce value
   • Records showing factual errors in the property description
     The Board of Revision considers valuation evidence such as appraisals and comparable sales.

3. File a complaint with the Board of Revision

   • In Seneca County, complaints against property valuation are generally accepted January 1 through March 31 each year.
   • The filing is made through the County Auditor’s office/Board of Revision.

4. Attend the hearing

   • You will have an opportunity to present your evidence.
   • Focus on why the property value is incorrect, rather than simply saying the tax bill increased. The Board evaluates valuation issues.

5. Appeal further if needed

   • If you disagree with the Board of Revision decision, Ohio law provides additional appeal options, including an appeal to the Ohio Board of Tax Appeals or, in some cases, the Court of Common Pleas.

For Seneca County, the Board of Revision is handled through the Seneca County Auditor's Office. The office lists the Board of Revision contact number as (419) 447-0692.

If you tell me your county and state (or confirm you’re in Seneca County, Ohio) and whether you’re challenging a recent reassessment, a new purchase value, or just a high tax bill, I can point you to the exact form and deadline.

If you’re in New Jersey, you generally appeal the assessed value of your property, not the tax rate itself. The key question is whether your assessment is higher than your property’s fair market value.

How the appeal works

1. Check your current assessment Find your property’s assessed value and the municipality’s assessment information. In Hoboken, the Tax Assessor’s office can provide property information and has an electronic appeal option.

2. Figure out what your home was actually worth Your strongest evidence is usually recent comparable sales of similar properties. You want to demonstrate that the market value of your property is substantially below the value implied by your assessment. NJ says the taxpayer has the burden of proving the assessment is unreasonable.

   Useful evidence can include:

   • Recent sales of comparable homes nearby
   • A professional appraisal
   • Evidence of significant defects or needed repairs
   • Your property's size, condition, age and features compared with the properties used by the assessor

3. File with the County Board of Taxation For a normal NJ assessment appeal, you generally file Form A-1 (Petition of Appeal) with your County Board of Taxation. The normal deadline is April 1, or 45 days after the bulk mailing of assessment notices, whichever is later. A municipal-wide revaluation/reassessment can change the deadline to May 1.

4. Attend the hearing Bring your evidence and be prepared to explain why the assessment doesn't reflect the property's market value. The Board's decision is based on the evidence submitted.

5. Appeal again if necessary If the County Board rules against you, you generally have 45 days from the judgment to appeal to the New Jersey Tax Court.

One important distinction

If your complaint is simply, “My property taxes are too high,” an appeal isn't necessarily the answer. NJ specifically says the taxes themselves cannot be appealed because they're driven by municipal budgets; you appeal the assessment.

If you're in Hoboken, I can walk you through the numbers for your particular property—e.g., how to estimate the assessment you should be appealing to, find comparable Hoboken sales, and determine whether an appeal is likely worth pursuing.

To appeal your property taxes because you think they are too high, you must first review your official property assessment notice and file a formal protest with your local county assessor or board of review within a strict window —usually 30 to 60 days of receiving your notice . Success depends on proving that your home's assessed market value is higher than its actual market value or that errors exist in your property's physical description.

Steps to Appeal Your Property Taxes

1. Check for Record Errors
   • Review your official property record card via your local municipality or county website.
   • Look for basic factual mistakes, such as an incorrect square footage, a wrong bedroom/bathroom count, or a nonexistent feature (like a basement or garage). Factual errors can often be fixed immediately by the assessor without a formal hearing.
2. Gather Evidence of Market Value
   • Find comparable sales ("comps") of 3 to 5 very similar homes in your immediate neighborhood that sold within the last 12 to 24 months.
   • Document physical damage, necessary major repairs (like a broken roof or failing HVAC), or deferred maintenance with photos and contractor estimates , which reduce market value.
   • Optionally, hire a professional real estate appraiser to conduct an official valuation if your home has unique or complex features.
3. Start with an Informal Review
   • Contact your local county assessor's office or township appraiser before the formal deadline.
   • Present your comparable sales or correction data. Many jurisdictions resolve over-assessments informally at this stage at no cost.
4. File a Formal Appeal
   • If the informal review fails, obtain the local appeal or complaint form from your county's Board of Review, Board of Equalization, or Value Adjustment Board.
   • Submit the paperwork and evidence packet before the strict calendar deadline . Missing this window means you forfeit the right to challenge your taxes for that cycle.
   • Note: Continue paying your standard property tax bill while the appeal is pending; if you win, the county will issue a refund or credit for the overpayment.

If you're in California, you generally appeal the assessed value of your property—not the tax rate itself. Since you're in the Los Angeles County area, here’s the practical process for L.A. County:

1. Check your assessed value.
   Look at your property tax bill or assessment notice. The key question is whether the county's assessed value is higher than the property's legally applicable value—often its fair market value as of the relevant assessment date.

2. Gather evidence showing a lower value.
   Useful evidence can include:

   • Comparable properties that sold around the relevant assessment date
   • Recent sales of your own property
   • Photographs/documentation of significant defects or needed repairs
   • Appraisals or other credible valuation information

   The appeals board considers evidence from both you and the Assessor when determining the property's value.

3. File an Assessment Appeal.
   For a regular L.A. County assessment, the filing period is July 2 through November 30 each year. For 2026, the deadline is November 30, 2026.

4. Pay the filing fee.
   L.A. County currently charges a $46 non-refundable filing fee. A fee waiver may be available if paying it would cause undue financial hardship.

5. Prepare for the hearing.
   You'll have an opportunity to present your evidence and explain why the assessment should be reduced. L.A. County offers both virtual and in-person hearings.

6. Keep paying your property taxes while appealing.
   Filing an appeal does not suspend your obligation to pay your property taxes. If you don't pay by the applicable deadlines, penalties can accrue even while your appeal is pending.

One important distinction

If you're saying "my house is worth less than the county says", an assessment appeal may be appropriate.

If you're saying "my property-tax bill is high because the tax rate or a particular charge is wrong," that's a different issue—the appeals board generally does not decide disputes over tax rates, local budgets, or tax policy.

L.A. County also holds free public education seminars on how to prepare an assessment appeal; the next listed one is August 19, 2026.

If you tell me your property's assessed value, roughly what you think it's worth, and the year you bought it, I can walk you through whether you likely have a good appeal and what evidence to submit.

Appealing your property taxes usually means challenging the assessed market value of your property set by your local government, rather than fighting the tax rate itself.

Step 1: Review Your Assessment and Check Deadlines

• Watch the calendar: Property tax assessment notices are time-sensitive. Most jurisdictions give you a strict window—typically 30 to 45 days from the date on the notice—to file an appeal. Missing this deadline usually means you forfeit your right to challenge the valuation for that year.
• Pull your property record card: Visit your local municipality or county assessor's website to look up your official property record card. Check for blatant factual errors (e.g., listing a finished basement that is unfinished, counting the wrong number of bedrooms/bathrooms, or overstating the lot size or square footage). Fixing an administrative error is often the fastest way to get a reduction on the spot.

Step 2: Gather Your Evidence

To win an appeal, you need objective, verifiable data—not just the opinion that your taxes are too high. Strong evidence includes:

• Comparable sales ("Comps"): Find 3 to 5 very similar properties in your immediate neighborhood (same style, comparable square footage, similar age) that sold for less than your current assessed value around the official valuation date.
• Recent independent appraisal: If you recently refinanced or bought the home, a recent professional fee appraisal can be hard evidence of your true market value.
• Condition documentation: Take clear photographs and get contractor estimates for major structural defects, un-repaired storm damage, or deferred maintenance that lowers your home's market appeal.

Step 3: File an Informal Appeal

• Contact the assessor: Many local assessment offices prefer or require an informal review before scheduling a formal hearing.
• Submit your data: Talk or write to the assessor’s office, present your comps or corrections, and see if they agree to adjust the value downward without a formal contest.

Step 4: File a Formal Appeal

• Complete local forms: If the informal review doesn't work out, obtain the official appeal or petition form from your local government website (often routed through a local Board of Review, Board of Equalization, or County Tax Board).
• Include your evidence: Attach your gathered documentation, clearly state your requested market value, and submit it before the statutory deadline.
• Pay your current bill on time: Keep paying your property taxes by the standard due date while the appeal is pending. Withholding payment can trigger penalties and interest. If your appeal succeeds, the county will issue a credit or refund for the overpayment later.

Step 5: Attend the Hearing

• Present professionally: If your case goes to a formal hearing before a local board or hearing officer, keep your presentation brief, factual, and focused strictly on market value rather than your personal ability to pay or complaints about rising government spending.
