Where to send your property tax payment

You pay property tax to your county assessor's office or county treasurer, depending on your state. The office that collects it varies — some counties have one department that handles both assessment and collection, others split the work. Your tax bill itself will say where to send payment, usually in a box at the bottom or on the back.

If you've lost your bill, call your county assessor's office directly. They can tell you the mailing address, the online payment portal if one exists, and your current balance. Most counties also list this information on their website under "property tax" or "treasurer."

Do not guess at the address. Sending a check to the wrong office delays posting and can result in a late fee, even though the error was not yours.

Key Takeaways

  • Your property tax bill tells you exactly where to send payment — check the bottom or back of the bill first.
  • You can usually pay by check, money order, online portal, or in person at the county treasurer's office.
  • Payment deadlines vary by state and county; missing the deadline triggers a late fee and sometimes a lien on your property.
  • If you pay online or by mail, allow time for processing before the deadline — online payments may take one to three business days to post.
  • Escrow accounts through your mortgage lender handle property tax payments automatically if your loan includes that option.

Payment methods and how long each takes

Most counties accept multiple payment methods. Check or money order by mail is the most common; allow five to seven business days for the payment to arrive and post. Online payment through the county's website or a third-party processor usually posts within one to three business days, though some systems are faster. In-person payment at the county treasurer's office posts immediately.

Credit card and debit card payments are available in many counties, but the processor often charges a fee — typically 2 to 3 percent of the amount. The county does not charge this fee; the payment processor does. Check whether the fee applies before you commit to that method.

Phone payment is less common but available in some counties. Call the number on your bill to ask. Wire transfer and ACH (automated clearing house) transfer are sometimes offered for large payments; ask the treasurer's office whether your county supports either.

What happens if you miss the deadline

Property tax deadlines vary by state — some are in March, others in June or December. Your bill shows your specific deadline. If you miss it, the county charges a late fee, usually a percentage of the unpaid amount. The exact percentage depends on your state and county; it ranges from 5 to 20 percent in most places.

After the late fee, unpaid taxes accrue interest at a rate set by your state, typically 8 to 12 percent per year. The longer you wait, the larger the total debt becomes. Some counties also file a tax lien against your property, which means the county has a legal claim on the house until the debt is paid. A lien makes it difficult to sell or refinance the property.

If property taxes remain unpaid for several years, the county may foreclose on the property and sell it at auction to recover the debt. This is rare for homeowners with mortgages, because lenders typically pay the taxes themselves to protect their investment, then add the cost to your loan balance. But if you own the home outright or the lender fails to pay, foreclosure is a real risk.

Using escrow to pay through your mortgage lender

If your mortgage includes an escrow account, your lender collects property tax (and homeowners insurance and mortgage insurance, if applicable) each month as part of your payment. The lender then pays the county on your behalf when the bill comes due. You do not send a separate check.

Escrow is standard for loans with less than 20 percent down payment and is optional for others. If you have escrow, your monthly mortgage statement shows the escrow portion separately. The lender is responsible for paying on time, so missing the deadline is their failure, not yours — though a lender's mistake can still damage your credit and create a lien.

If you do not have escrow and want it, contact your lender to ask whether you can set it up. If you have escrow and want to remove it, you typically need at least 20 percent equity in the home and must request it in writing. Removing escrow means you take on the responsibility of paying property tax yourself.

Paying back taxes and setting up a payment plan

If you owe multiple years of unpaid property tax, the total can become large quickly because of accumulated late fees and interest. Many counties offer payment plans that let you pay the debt over time instead of in one lump sum. Contact your county treasurer's office to ask whether a plan is available and what the terms are.

Payment plans usually require a down payment and monthly installments over 12 to 36 months. Interest and fees continue to accrue during the plan, so the total you pay is higher than if you paid in full immediately. But a plan prevents foreclosure and gives you time to catch up.

Some states also offer tax deferral programs for homeowners who are elderly, disabled, or have very low income. These programs delay payment until the home is sold or the owner passes away. may be able to access and terms vary widely by state. Ask your county assessor's office whether your state has a deferral program and whether you might may have access to.

Keeping records and confirming payment

Keep your property tax bill and proof of payment for your records. If you pay by check, keep a copy of the cancelled check or your bank statement showing the payment. If you pay online, print or save the confirmation page. If you pay in person, ask for a receipt.

After you pay, allow time for the payment to post to your account before the deadline passes. If you mail a check, send it at least one week early. If you pay online, do it at least three business days before the deadline. Do not wait until the last day.

If you do not see the payment posted within the expected time, contact the county treasurer's office. Provide your confirmation number or proof of payment. A missing payment can trigger a late fee even if you sent it on time, so follow up if something seems wrong.

Frequently Asked Questions

Can I pay property tax online in every county?

Most counties now offer online payment, but not all. Check your tax bill or the county treasurer's website to see whether your county has a portal. If not, you can pay by mail, in person, or by phone. Call the treasurer's office to ask which methods are available in your county.

What if I disagree with the amount on my bill?

Contact your county assessor's office, not the treasurer. The assessor determines the value of your property and calculates the tax. If you believe the value is wrong, you can file a formal appeal or assessment challenge within a set time frame, usually 30 to 60 days of receiving the bill. The process and deadline vary by state.

Do I have to pay property tax if I'm behind on my mortgage?

Yes. Property tax is separate from your mortgage payment. If your loan includes escrow, the lender pays the tax automatically. If it does not, you must pay it yourself even if you are behind on the mortgage. Unpaid property tax can result in a lien or foreclosure independent of mortgage problems.

What happens if my lender pays the property tax but I didn't authorize it?

If your loan includes escrow, the lender is authorized to pay property tax as part of the agreement you signed. The cost is added to your loan balance. If your loan does not include escrow and the lender paid anyway, contact them immediately to understand why and to clarify your account.

Can I deduct property tax from my federal income tax?

You may be able to deduct property tax on your federal return, but the rules changed in 2017. Consult a tax professional or the IRS website to determine whether you may have access to and how much you can deduct. This is separate from paying the property tax itself to your county.
