To lower your property taxes, you need to shrink the assessed value that your local tax rate is applied to. That means three things, in order of effort: correct any errors on your assessment record, claim every exemption you qualify for, and appeal the assessment itself when your home’s assigned value is higher than what it would sell for. Local governments multiply a tax rate, often called a millage rate, against your assessed value, so anything that pulls that value down pulls your bill down with it.1Legal Information Institute. Millage
Check Your Assessment Record for Errors
Every property has a record card on file at the assessor’s office listing the raw data used to value your home. Errors on that card quietly inflate your assessment year after year until someone catches them.
Pull your card and read it line by line. Common problems: overstated square footage, the wrong number of bedrooms or bathrooms, a finished basement listed when yours is unfinished, incorrect lot dimensions, or structures still on the record that have been torn down. Pools, garages, and outbuildings sometimes linger on cards after they’re gone. If you find a factual mistake, call the assessor’s office. Many will correct straightforward data errors without a formal appeal or hearing.
While you’re looking at the card, also confirm the assessment ratio. Some jurisdictions tax property at 100 percent of market value; others use a fraction like 50 or 80 percent. An error in either the market value estimate or the ratio applied to it will inflate your bill, so verify both numbers before you decide whether you have a case.
Claim Every Exemption You Qualify For
Exemptions cut the taxable portion of your home’s value before the tax rate is applied. They vary a great deal by jurisdiction, so ask your local assessor or tax collector which programs are available where you live.
Homestead Exemption
The homestead exemption is the most widely available form of property tax relief and generally requires the home to be your primary residence. It subtracts a fixed dollar amount from your assessed value; the amount ranges from a few thousand dollars to six figures depending on the state or county. You usually apply once, though some places require annual renewal. Moving out or converting the home to a rental ends the benefit.
Senior and Disability Exemptions
Many jurisdictions offer extra reductions for homeowners 65 or older, often with a household income cap so relief goes to people on fixed budgets. Income thresholds commonly land somewhere around $40,000 to $60,000 in annual household income. You’ll typically need proof of age — a birth certificate, driver’s license, or passport. Homeowners with permanent disabilities may qualify for similar reductions by providing documentation such as a Social Security Administration determination.
Veteran Exemptions
Veterans with a service-connected disability frequently qualify for a property tax exemption, and some jurisdictions offer partial exemptions to all veterans regardless of disability status. You’ll generally need a DD-214 or a Department of Veterans Affairs letter confirming the disability rating. The exemption often scales with the rating; veterans rated 100 percent disabled receive a full property tax exemption in some areas.
Keeping the Exemption When Things Change
If you move your home into a living trust but keep living there as the beneficiary, most jurisdictions let you keep the homestead exemption. Surviving spouses may retain an exemption originally granted for a deceased spouse’s age or disability, though the rules differ by state. The common thread across nearly every exemption is that the home must remain your primary residence. Renting it out, even for a short stretch, can cost you the benefit.
Circuit Breakers and Deferrals
Two programs sit outside the traditional exemption system and are worth checking separately.
About 30 states and the District of Columbia run “circuit breaker” programs that issue a credit or rebate once your property tax bill exceeds a set percentage of household income. These are usually claimed on your state income tax return rather than through the assessor’s office, which is why homeowners often miss them.
Some states also let seniors and low-income homeowners defer property tax payments until the home is sold or transferred. The deferred amount becomes a lien on the property and is repaid, with interest, from the sale proceeds. A deferral doesn’t reduce your taxes; it postpones them. That’s cash-flow relief, not a savings, but it can keep someone in their home.
Start With an Informal Review
Before filing a formal appeal, ask the assessor’s office for an informal review. Many jurisdictions offer this as a first step and it’s often the fastest way to resolve a dispute. You sit down with an assessor, or submit your concerns in writing, and explain why the valuation looks wrong. If the assessor agrees, the value gets adjusted without a hearing.
Bring evidence: photos of property damage, a short list of recent comparable sales, or the data errors you spotted on the record card. Even if the informal review doesn’t fully resolve things, it gives you a preview of the assessor’s reasoning and sharpens your formal appeal. There’s usually no fee and no deadline risk, because the informal process runs alongside the formal appeal timeline rather than replacing it.
Build Evidence for a Formal Appeal
If the informal route doesn’t work, a formal appeal requires you to show that the assessed value is higher than the home’s actual market value. Studies suggest that roughly 40 to 60 percent of formal property tax appeals result in a reduced assessment, and the strength of your evidence is what moves that number.
Comparable Sales
Comparable sales, or “comps,” are the backbone of most successful appeals. Look for homes like yours in size, age, condition, lot size, and location that sold in the last six to twelve months. The closer the match, the more persuasive it is. Same neighborhood or subdivision is ideal. Stick to arm’s-length transactions between unrelated buyers and sellers; foreclosures, short sales, and family transfers don’t reflect true market value.
Appraisal standards don’t set a specific distance radius for comps, but closer is better.2The Appraisal Foundation. Uniform Standards of Professional Appraisal Practice (USPAP) 2020-2021 Edition If sales are sparse in your neighborhood, widen the search, but be ready to explain why those properties still compare to yours.
An Independent Appraisal
A professional appraisal from a licensed appraiser gives you a detailed, independent opinion of value that boards tend to find credible. Single-family appraisals typically run $300 to $500 depending on size, location, and complexity. If a successful appeal saves more than the appraisal fee over even a few years, the investment usually pays off.
Photos and Condition
Photograph anything the assessor may not know about: foundation cracks, an outdated kitchen, water damage, a deteriorating roof. Written repair estimates from licensed contractors add weight. Your goal is to show the board that the home’s real condition doesn’t match the condition the assessment assumed.
File the Appeal on Time
Deadlines are strict and vary. Many jurisdictions give you 30 to 90 days after the assessment notice arrives. Miss the date and you almost always lose the right to challenge the value for that year, so put it on the calendar the moment your notice comes in.
Get the appeal form from your local board of equalization, board of review, or the assessor’s website. It will ask for your parcel identification number, the current assessed value, the value you believe is correct, and the basis for your claim. Attach the comps, the appraisal, the photos, and any repair estimates. Filing fees vary widely: some jurisdictions charge nothing, others charge from under $50 to several hundred dollars depending on the property’s value.
File online where you can and save the digital receipt. If you mail it, use certified mail with a return receipt. Keep copies of everything.
One trap catches homeowners every year: in most jurisdictions, filing an appeal does not pause your obligation to pay property taxes. Skip the payment and you’ll rack up late penalties and interest that can erase any savings from a win. Pay on time. If the assessment is later reduced, you’ll receive a refund or credit for the overpayment.
The Hearing and What Comes After
Some hearings are informal conversations at a conference table; others are structured more like a courtroom. You’ll get the date by mail. Keep your presentation focused on the facts that affect value — comparable sales and property condition — rather than complaints about the tax rate or local spending, which the board can’t act on.
The decision comes in writing. A reduction produces a revised bill. If the appeal is denied, most states let you escalate to a higher state tax court or board within a set window; those proceedings tend to be more formal and take longer.
A successful reduction generally stays in place until the next reassessment cycle, which may be one year or several depending on where you live. A single appeal can therefore produce savings that compound across multiple tax years.
Make Sure the Savings Reach Your Monthly Payment
If your mortgage includes an escrow account for property taxes, a lower assessment doesn’t automatically lower your monthly payment. The servicer collects estimated tax payments each month and pays the taxing authority on your behalf, and it’s required to perform an escrow analysis at least once a year. If that analysis shows a surplus of $50 or more, the servicer must refund the excess within 30 days. Surpluses under $50 may be refunded or credited toward the next year’s payments.3Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts
After a win, send your servicer documentation of the reduced assessment. Servicers aren’t required to run an off-cycle analysis on request, but flagging the change helps make sure it shows up in the next annual review. Your escrow portion of the payment should then drop to match the new tax obligation.
A Note on Federal Taxes
If you itemize on your federal return, property taxes are deductible as part of the state and local tax (SALT) deduction.4Internal Revenue Service. Publication 530 (2025), Tax Information for Homeowners The SALT deduction is capped at $40,000 per year ($20,000 if married filing separately), and that cap covers property taxes, state income taxes, and state sales taxes combined.5Internal Revenue Service. Topic No. 503, Deductible Taxes Lowering your property tax bill directly saves money at the local level, but the federal deduction shrinks by the same amount, so plan around the actual number.
If a successful appeal produces a refund for taxes you already deducted, the refund may be taxable in the year you receive it under the tax benefit rule, but only to the extent the original deduction reduced your federal tax.6Internal Revenue Service. Publication 525 (2024), Taxable and Nontaxable Income If you didn’t itemize the year you paid the tax, or the deduction gave you no benefit because you were already over the SALT cap, the refund isn’t taxable.
