Your refund amount depends on what you overpaid and when
A property tax refund is money your county or municipality owes you because you paid more in property taxes than you actually owed. The amount is not fixed — it depends entirely on the difference between what you sent in and what the tax bill required. If you paid $5,000 and owed $4,800, your refund is $200. If you overpaid by $50, your refund is $50.
The most common reason for overpayment is an error in the assessed value of your property, a change in your home's status (like a new exemption you became may have access to to), or a calculation mistake by the assessor's office. Sometimes you overpay because you made an extra payment by accident, or because an escrow account held too much. The refund process starts when the assessor corrects the record, and you then have the right to the difference.
Key Takeaways
- Your refund amount equals the difference between what you paid and what you actually owed in property taxes for that year.
- The assessor's office calculates the refund once they correct the assessed value or fix an error on your account.
- You can request a copy of your tax bill and assessment record to verify the calculation yourself before accepting the refund.
- Refunds are usually issued by check or applied as a credit to the next year's bill, depending on your county's process.
- Interest on refunds varies by state and county — some pay it automatically, others only if you request it in writing.
How to find your assessed value and calculate the difference
Start by getting a copy of your current property tax bill and your assessment record. Both are public documents and available from your county assessor's office — usually online through their website, or by calling or visiting in person. The tax bill shows what you paid; the assessment record shows the assessed value the bill was based on.
The assessed value is the dollar amount the assessor decided your property is worth for tax purposes. It is not the market value (what you could sell it for). Your tax bill is calculated by multiplying the assessed value by the tax rate your county sets. If the assessed value was wrong, the bill was wrong, and you overpaid.
Once you have both documents, the math is straightforward: take your total payment for the year and subtract the total amount that should have been due. If the number is positive, that is your refund. For example, if your bill said you owed $4,200 but you paid $4,500, you overpaid by $300.
What the assessor's office will tell you about the refund amount
When you contact your assessor's office about an overpayment, they will calculate the refund for you — you do not have to do it yourself. Tell them the tax year in question and explain why you believe you overpaid (a corrected assessment, a new exemption, an error you found). They will pull your account, review the records, and tell you the exact amount owed back to you.
Ask them to send you a written statement showing the calculation. This statement should show the original assessed value, the corrected assessed value (if that is why you are getting a refund), the tax rate, and the refund amount. Having this in writing protects you and gives you a record if there are questions later.
If you disagree with their calculation, ask them to explain each step. The assessor's office is required to show their work. If you still think the number is wrong, you may have the right to challenge the assessment through your county's formal appeal process — but that is a separate step from collecting a refund that is already owed.
Interest on your refund, if your state or county pays it
Some states and counties add interest to property tax refunds if the overpayment was large or lasted more than a certain amount of time. Interest rates and rules vary widely. Some counties pay interest automatically; others only pay it if you request it in writing and meet specific conditions.
When you contact the assessor's office, ask directly: "Does this county pay interest on property tax refunds, and if so, at what rate and for what time period?" Write down the answer. If they say yes, ask whether you need to request it or whether it will be included automatically. If they say no, ask whether you have the right to request it anyway — some counties have an appeal process for interest claims.
Interest, when it is paid, is usually calculated from the date you overpaid to the date the refund is issued. The longer the money was held, the more interest accrues. This is another reason to request your refund as soon as you discover the overpayment.
How refunds are issued and when you will receive yours
Most counties issue refunds by check mailed to your address on file. Some allow you to request a direct deposit to your bank account instead — ask when you contact the assessor's office whether that option is available. A few counties explore the refund as a credit to your next year's tax bill rather than sending money back, though you can usually request a check instead.
The time it takes to receive a refund depends on the county's workload and whether they need to investigate the reason for the overpayment. straightforward cases — where the error is clear and the amount is small — may be processed in a few weeks. Complex cases or large refunds may take two to three months. Ask the assessor's office for an estimate when you request the refund.
Once the refund is approved and issued, you will receive a notice in the mail explaining the amount and the reason. Keep this notice with your tax records. If you do not receive the refund within the timeframe you were given, contact the assessor's office again with the reference number from the notice.
What to do if you think the refund amount is wrong
If the assessor's office calculated a refund but you believe the amount is incorrect, ask for a detailed breakdown of how they arrived at that number. Request the original tax bill, the corrected assessment, the tax rate used, and the calculation itself. Go through it line by line.
Common mistakes include using the wrong tax rate, forgetting to include a penalty or fee that should have been refunded, or explore the refund to the wrong year. If you find an error, point it out in writing and ask for a corrected calculation. Keep copies of everything you send.
If the assessor's office will not correct the amount and you still believe they are wrong, you may have the right to file a formal appeal or complaint with your county's board of supervisors or equivalent body. The process and important date vary by location, so ask the assessor's office what your options are.
Frequently Asked Questions
Can I get a refund for property taxes I paid in previous years?
Yes, but there is usually a time limit. Most states allow refunds for three to five years of overpayment, though some go back further. Contact your assessor's office and ask how far back they can go. If you overpaid more than five years ago, you may still have a claim, but you will need to ask about your state's specific rules.
What if my mortgage lender paid the property taxes from my escrow account?
The refund still belongs to you, but the check may be sent to your lender instead of to you, since they paid the bill. Contact your lender and ask them to forward the refund to you, or contact the assessor's office and ask them to send it directly to you. You may need to provide written permission from your lender.
Do I have to pay taxes on the refund I receive?
Generally, no. A property tax refund is a return of money you overpaid, not income. However, if you deducted the overpaid amount on your federal income tax return in a previous year, you may owe tax on the refund. Consult a tax professional if you are unsure whether this applies to you.
What if the assessor's office says I do not have a refund coming?
Ask them to explain why. Request a copy of your tax bill and assessment record for the year in question. Review them yourself to see whether you actually did overpay. If you believe you did, ask the assessor's office to show you the calculation that led to their conclusion. If you still disagree, you may have the right to challenge the assessment or file a complaint.
How long do I have to request a refund before it expires?
This depends on your state and county. Some have no time limit; others require you to request a refund within a certain number of years (often three to five). Contact your assessor's office and ask about the important date in your area. If you think you overpaid, do not wait — request information about your refund now.
