Where to file depends on what kind of refund you're owed
Property tax refunds come from different places depending on why you're owed money. If your county assessor overvalued your home, you file with your county assessor's office or your county board of appeals. If you paid property taxes on a home you no longer own, you file with your county treasurer or tax collector. If you overpaid your escrow account through your mortgage lender, you contact the lender directly. The first step is figuring out which situation matches yours, because each one has its own filing process and timeline.
Most property tax refunds are handled at the county level, not the state level. Your county assessor's office and county treasurer's office are the two main places you'll deal with. Some states also have property tax relief programs that issue refunds to homeowners who meet income or age requirements — those go through your state revenue department or state tax authority.
Key Takeaways

- Overpayment refunds from your county are requested through your county treasurer or tax collector, and require proof of what you paid and what you owed.
- Escrow overpayments from your mortgage lender are handled by contacting your lender's servicing department with your loan number and recent statements.
- State property tax relief refunds (for seniors, disabled homeowners, or low-income households) are filed through your state revenue department and have annual deadlines that vary by state.
- Most county refunds take 30 to 90 days to process once approved, though some states take longer.
Filing an assessment appeal with your county
If you believe your home's assessed value is too high, you file an appeal with your county assessor's office or county board of appeals. The deadline is usually 30 to 45 days from the date you receive your assessment notice — check your notice for the exact date, because missing it closes your right to appeal that year. Some counties allow you to file online through their assessor's website; others require a paper form mailed or delivered in person.
You'll need to gather evidence that your home is worth less than the assessed value. This can include recent appraisals, comparable sales of similar homes in your area, photographs of damage or needed repairs, or a professional home inspection report. Your county assessor's office can tell you what documents they accept. File your appeal form with whatever supporting documents you have — you don't need a lawyer or appraiser, though some people hire one if the assessed value is significantly high.
After you file, the assessor's office reviews your appeal and either agrees to lower the value or denies it. If they deny it, you can appeal to your county board of appeals (also called the assessment review board or equalization board). That second appeal usually has its own deadline, typically 30 days after the assessor's decision. If the board also denies your appeal, some states allow a third appeal to tax court, but that usually requires a lawyer.
Requesting an overpayment refund from your county treasurer
If you paid more property tax than you owed — because you made a duplicate payment, paid on a property you no longer own, or the tax bill was corrected downward — you request a refund from your county treasurer or tax collector. Contact them by phone, mail, or in person at their office. You'll need your property address, parcel number (on your tax bill), and the years you overpaid.
Bring or send proof of what you paid. This can be cancelled checks, bank statements, credit card receipts, or payment confirmations from your county's online payment system. The treasurer's office will verify the amount you paid against their records and calculate what you're owed. Processing time varies by county — some issue refunds within 30 days, others take 60 to 90 days. A few counties issue refunds by check; others deposit directly to a bank account if you provide it.
If your county denies your refund request, ask them in writing why. Some counties have a formal appeal process for disputed refunds, usually through the county auditor's office or a tax review board. Keep copies of everything you submit.
Getting an escrow refund from your mortgage lender
Your mortgage lender holds an escrow account that pays your property taxes and homeowners insurance on your behalf. If you overpaid into that account — because you made extra payments, your tax bill dropped, or the lender miscalculated — you're owed a refund from the lender, not from your county.
Contact your lender's servicing department (the number is on your mortgage statement). Have your loan number and recent statements ready. Ask them to review your escrow account and calculate any overage. Lenders are required by federal law to refund escrow overages, though the timing varies. Some lenders issue refunds automatically once a year; others require you to request it. The refund typically arrives within 30 to 45 days as a check or direct deposit.
If your lender refuses to refund an overage you believe you're owed, you can file a complaint with your state's banking regulator or the Consumer Financial Protection Bureau. Keep records of all your payments and the lender's responses.
State property tax relief programs that issue refunds
Some states offer property tax relief refunds to homeowners who meet income limits, age requirements, or disability status. These are separate from county refunds and are filed through your state revenue department or state tax authority. Common programs include homestead exemptions, senior property tax relief, and disabled homeowner exemptions.
Each state sets its own income limits, age thresholds, and filing deadlines. Some states process these as automatic refunds if you filed a state income tax return; others require a separate application. Check your state's revenue department website or call their property tax assistance line to find out which programs you may be able to use and what the current deadline is. Deadlines often fall in spring or early summer, so don't wait until fall to file.
You'll typically need to provide proof of income (tax returns or W-2s), proof of ownership (deed or mortgage statement), and proof of residency. Some states allow you to file online; others require paper forms mailed in.
Tracking your refund status
Once you've filed, ask for a confirmation number or receipt. Keep it with your filing documents. Contact the office where you filed (county assessor, county treasurer, or state revenue department) to check on your refund status. Most county offices can tell you over the phone whether your request was received and where it stands in the review process.
If your refund is taking longer than the stated timeline, call again and ask for a specific expected date. If you filed an assessment appeal, the assessor's office should tell you when they'll make a decision. If you filed for a state relief program, the revenue department can tell you the average processing time for that program that year.
If your refund doesn't arrive within the stated timeframe, follow up in writing (email or certified mail) and ask for a written explanation of the delay. Keep copies of all correspondence.
What to do if your refund request is denied
If your county assessor denies your appeal, you can appeal to your county board of appeals. If the board denies it, you may be able to appeal to tax court, though this usually requires hiring a lawyer and costs money upfront. Some counties offer free or low-cost mediation before a formal appeal, which can be faster and cheaper.
If your county treasurer denies your overpayment refund, ask in writing why. Request a detailed explanation of how they calculated what you owe. If you believe they made an error, ask about their formal dispute process. Some counties have an ombudsman or auditor's office that can review disputed refunds.
If a state relief program denies your refund, the denial letter should explain why. Many states allow you to appeal a denial if you believe the decision was wrong. The appeal process and deadline are usually listed on the denial letter or on the state revenue department's website.
Frequently Asked Questions
How long does it take to get a property tax refund?
County assessment appeals typically take 30 to 90 days from the time you file until the assessor makes a decision. Overpayment refunds from your county treasurer usually arrive within 30 to 90 days of approval. Escrow refunds from your mortgage lender typically take 30 to 45 days. State relief program refunds vary widely by state — some process in 30 days, others take several months.
Do I need a lawyer to file an assessment appeal?
No. You can file an assessment appeal yourself with just your property tax notice and supporting documents like comparable sales or repair estimates. Many people do this without a lawyer. You only need a lawyer if your appeal is denied and you want to appeal to tax court, which is a formal legal process.
What if I can't find my property's parcel number?
Your parcel number is on your property tax bill. If you don't have the bill, call your county assessor's office or county treasurer's office with your property address, and they'll give you the number. You can also search for it on your county's online property records website, which is usually free and open to the public.
Can I file a property tax refund for a home I sold?
Yes, but only for the year you sold it. If you overpaid property taxes for that year, you can request a refund from the county treasurer. If the home was reassessed at a lower value after you sold it, you generally cannot appeal that assessment — the new owner would have to file the appeal. Contact your county treasurer to learn about you're owed a refund for the year of sale.
What happens if I miss the deadline to file an assessment appeal?
You lose the right to appeal that year's assessment. You can appeal the next year's assessment if you receive a new notice. Some counties allow late appeals in rare cases (like if you didn't receive the notice), so call your assessor's office to ask if an exception is possible, but don't count on it.
