Where your refund comes from and who sends it

A property tax refund happens when you have paid more tax than you actually owe — usually because you overpaid during the year, your assessment was reduced, or you became newly exempt from taxation. The refund comes from your county assessor's office or tax collector's office, not from a state or federal agency. The office that collected your payment is the one that processes the refund.

The process is not automatic. You have to request the refund, and the steps depend on whether you discovered the overpayment yourself or whether the assessor's office identified it. In most cases, you will need to submit a written request with documentation showing what you paid and why you are owed money back.

Timing matters. Many counties have a statute of limitations on refund claims — typically three to five years, though this varies by state. If you discover an overpayment from several years ago, you may still be within the window to claim it, but waiting longer narrows your options.

Key Takeaways

  • Contact your county assessor's office or tax collector's office directly, because they process refunds and can tell you whether you are owed money and what documents you need to submit.
  • You will need proof of payment (a cancelled check, receipt, or payment confirmation) and documentation of why the refund is due — such as a corrected assessment notice or proof of a tax exemption you now may have access to for.
  • Most counties require a written request, not an online form, so you may need to mail or deliver documents in person to the tax office.
  • Refunds typically take two to six months to process once your request is received, though some counties are faster and some slower depending on their workload.
  • If your refund claim is denied, you have the right to appeal, usually through a county board of equalization or similar body, and you may need to file that appeal within a specific timeframe.

Gathering the documents you need before you contact the office

Before you call or visit your county tax office, collect three things: proof that you paid the tax, documentation of the overpayment, and your property identification number.

Proof of payment can be a cancelled check, a credit card statement showing the charge, a receipt from an online payment, or a letter from the tax collector confirming receipt. If you paid through an escrow account (your mortgage lender paid on your behalf), you will need a statement from the lender showing the amount they paid and the date.

Documentation of the overpayment depends on why you are owed money. If your assessment was reduced, you need the new assessment notice showing the lower value. If you became exempt — because you turned 65, became disabled, or your property changed use — you need the exemption approval letter from the assessor. If you straightforward overpaid during the year, you need your payment records and a calculation showing the difference between what you paid and what you owed.

Your property identification number (sometimes called the parcel number or APN) appears on your tax bill and assessment notice. Having it ready speeds up the conversation with the tax office.

How to submit your refund request to the right office

Start by identifying which office handles refunds in your county. In some counties it is the assessor; in others it is the tax collector or treasurer. The fastest way to find out is to call your county assessor's office and ask them directly. They will either process your request or tell you which office to contact.

Most counties do not have an online refund request form. Instead, you will write a letter or complete a paper form available at the tax office. The letter should state your name, address, property identification number, the tax year in question, the amount you believe you overpaid, and the reason for the overpayment. Attach copies (not originals) of your proof of payment and supporting documents.

You can submit your request by mail, by hand delivery to the tax office, or sometimes by email if the office has posted an email address on their website. If you mail it, send it certified mail with return receipt so you have proof of delivery. Keep a copy for your records.

Some counties have a formal process form for refunds. Ask the tax office whether one exists for your situation. If it does, use it — it ensures you provide the information they need in the format they expect.

What happens after you submit your request

Once the tax office receives your request, they will verify that you paid the amount you claim and that the reason for the refund is valid. This verification step typically takes two to four weeks. During this time, the office may contact you if they need additional information or clarification.

If your request is approved, the office will issue a refund. The method depends on the county: some mail a check, some issue a credit against future tax bills, and some offer direct deposit if you provide banking information. Ask the office which method they use and whether you have a choice.

The time from approval to receiving your money varies. A check can take two to four weeks to arrive by mail. A credit against future taxes is applied when ready but you do not receive cash. Direct deposit, if available, is usually the fastest option.

If your request is denied, the office will send you a written explanation of why. This explanation is important because it tells you what you would need to prove to appeal the decision.

Appealing a denied refund claim

If the tax office denies your refund request, you have the right to appeal. The appeal process and timeline vary by county, but most counties have a board of equalization or similar body that hears tax disputes.

To appeal, you typically must file a formal notice of appeal within a specific timeframe — often 30 to 60 days from the denial letter, though this varies. The denial letter should state the important date. File the appeal with the same office that denied your claim, or with the board of equalization if the letter directs you there.

In your appeal, explain why you believe the denial was wrong. Provide any additional evidence you have — for example, if the office said you did not provide proof of payment, submit that proof now. If the office said your assessment was not actually reduced, submit the assessment notice showing the reduction.

The board will review your appeal and either uphold the denial or overturn it. Some boards hold hearings where you can present your case in person; others decide based on written submissions. Ask the office which process applies to your county.

Refunds when your property was sold or transferred

If you sold the property or transferred it to another owner, the refund process becomes more complex because the tax office must determine who is may have access to to the money.

If you overpaid taxes for a year when you owned the property, you are generally may have access to to the refund even if you no longer own it. However, the tax office may require documentation showing the sale date and the new owner's information. If the overpayment covers a period before and after the sale, the refund may need to be split between you and the new owner based on how long each of you owned the property during that tax year.

Submit your refund request as usual, but include a copy of the deed or sale document showing when ownership changed. The tax office will handle the calculation and determine how much of the refund belongs to you.

When the refund is for a property you inherited

If you inherited the property and discovered that the previous owner overpaid taxes, you may be able to claim that refund as the current owner. However, the tax office may require proof that you are the legal owner — typically a copy of the deed in your name or a letter from the probate court confirming your inheritance.

The refund belongs to the estate of the previous owner, not to you personally, unless the will or probate court order specifically assigns it to you. If the estate is still in probate, you may need to work with the executor or administrator to file the claim. If probate is closed, you will need documentation showing that you have the legal right to claim the refund on behalf of the estate.

Contact the tax office and explain the situation. They will tell you what documents they need to process the claim. This type of refund often takes longer because the office must verify the ownership transfer and the legal authority to claim the money.

Frequently Asked Questions

How long do I have to claim a property tax refund?

Most states allow three to five years from the date of overpayment, though some allow longer. Check your state's statute of limitations by contacting your county assessor's office. If you are near the important date, submit your request when ready.

Can I claim a refund for taxes paid by my mortgage lender through escrow?

Yes. Request a statement from your lender showing the amount they paid and the date. Submit that statement with your refund request. The refund may go to you or to the lender depending on your loan agreement and the county's policy.

What if I paid property taxes on a property I did not actually own?

You may still be owed a refund, but you will need to prove you paid and that you had no legal obligation to do so. Bring your payment records and any documentation showing the actual owner's name. The tax office will investigate and determine whether a refund is due.

Do I owe 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 taxes on a federal income tax return, you may need to report the refund to the IRS. Consult a tax professional if you are uncertain.

What if the tax office says I owe money instead of getting a refund?

This can happen if the office discovers you underpaid in a previous year. Ask for an itemized explanation of the calculation. If you disagree, you have the right to appeal through the same board of equalization process used for denied refunds.
