To change the address on your property tax bill, send a signed address-change request to your county assessor’s office (or, in some places, the treasurer or tax collector) with your parcel number, the property’s physical address, your new mailing address, and a copy of your government-issued photo ID. Most counties process the update for free and offer several submission channels: an online portal, email or fax, certified mail, or a walk-in visit. The property owner is responsible for keeping this address current, and a bill sent to the wrong place does not excuse a late payment.
Which Office Handles the Change
Property taxes are administered locally, so the office you contact depends on your county or municipality. In most places, the county assessor maintains the master database of ownership records and mailing addresses. The treasurer or tax collector issues the bill but usually pulls address data from the assessor’s files. A request sent to the wrong office can sit untouched for weeks.
Start on your county’s website and look for an “assessor,” “property tax,” or “assessment and taxation” department. Many counties post the address-change form directly on that page. If the site isn’t clear, call the assessor and ask which department handles mailing-address updates for the tax roll.
What to Gather Before You Submit
The single most important item is your parcel number, sometimes called a Property Index Number (PIN) or tax identification number. It’s the unique code the county uses to identify your property, and you’ll find it on any previous tax bill or assessment notice. Without it, the office has no reliable way to match your request to the right account.
Beyond the parcel number, have these ready:
- Your full legal name, matching the name on the property’s title records. If the property is held by a trust or LLC, an authorized signer for that entity typically needs to submit the request.
- The property’s physical address, which stays the same regardless of where you want bills sent.
- Your new mailing address. Double-check apartment or unit numbers.
- A government-issued photo ID. Many offices require a copy for mailed or in-person requests; online portals often verify identity through account credentials instead.
Most jurisdictions require the property owner’s signature on the form. A few require extra documentation for trusts, corporations, or recently transferred properties, such as a copy of the recorded deed or authorization documents. The form is usually available as a downloadable PDF on the assessor’s website or as a paper form at the county building. Address changes are typically free.
How to Submit the Request
County offices generally accept address changes through several channels. The right one depends on how much confirmation you want.
- Online portal. The fastest option. Many assessor websites let you log in, enter your parcel number, and update the address directly. You’ll usually get a confirmation number or email receipt. Some portals require you to create an account first.
- Email or fax. Some offices accept a signed, scanned form. You may need to type your name as a digital signature and attach a copy of your ID.
- Mail. Send the signed form and a photocopy of your ID by certified mail with return receipt requested. The return receipt gives you a paper trail proving the office received your request, which matters if a billing dispute arises later.
- In person. Walking into the assessor’s or treasurer’s office lets you hand over the form, show your ID on the spot, and confirm the change was entered before you leave. Bring the original form and your ID.
After You Submit
Processing times vary. Some online portals update your address in real time; mailed or in-person requests may take several weeks. Check your county’s online property records database periodically to confirm the new address appears on your account. Some offices send a confirmation notice to the new address once the update is complete.
Timing matters relative to the billing cycle. If you submit your change after the current year’s bills have already been printed and mailed, that bill will still go to your old address. Don’t wait for the bill to find you. Look up your account balance online or call the tax office to confirm the amount owed and the deadline, and pay based on what you find.
If You Have a Mortgage Escrow Account
Homeowners whose mortgage payments include a property tax escrow face an extra layer of coordination. Your mortgage servicer typically obtains your tax amount directly from the county using your parcel number and pays the bill from your escrow account before the deadline. In theory, the mailing address matters less because the servicer is paying on your behalf.
In practice, update your address with both the county and your mortgage servicer. Some tax offices don’t release bill data electronically to third-party servicers and instead mail the bill directly. If that bill goes to an old address and your servicer never receives it, your taxes could go unpaid. If you get a notice from the county saying your taxes haven’t been paid, the Consumer Financial Protection Bureau recommends contacting your servicer right away while also verifying the account status directly through your county’s online tax portal.
Watch Out for Exemptions Tied to the Property
If you receive a homestead exemption, senior exemption, veteran exemption, or another property tax break tied to your primary residence, an address change deserves extra caution. These exemptions generally require you to occupy the property as your legal residence. When you change your mailing address to a different location, the assessor’s office may read that as a sign you’ve moved away.
That interpretation doesn’t automatically disqualify you. Plenty of owners receive mail at a P.O. box, a business address, or a relative’s home for convenience or privacy. But in many jurisdictions, you’re legally required to notify the tax commissioner or assessor if you no longer meet the occupancy requirements for your exemption. If the county flags your account, you may need to confirm that you still live at the property. Keep documentation of your continued occupancy handy, such as a driver’s license showing the property address or utility bills in your name at that location.
If you’re genuinely moving away and will no longer occupy the property as your primary residence, you’ll lose the exemption. Failing to report this change can result in back taxes, penalties, and interest for the years you claimed an exemption you didn’t qualify for. Reporting the change proactively is better than having the county discover it during an audit.
USPS Forwarding Is Not a Substitute
Setting up mail forwarding through the U.S. Postal Service when you move is smart, but it isn’t a substitute for updating your address with the assessor. Standard USPS forwarding lasts six months and can be extended to a maximum of one year. After that, mail sent to your old address simply stops reaching you. Property tax bills arrive on an annual or semi-annual cycle in most places, so a single missed forwarding window can mean a missed bill. Even during the forwarding period, delivery isn’t guaranteed for every piece of government mail.
What Happens If You Don’t Update Your Address
An outdated address on file does not pause your tax obligation. The county mails the bill to whatever address it has, and if you don’t receive it, the taxes still come due on the original deadline. Penalties for late payment vary by jurisdiction but commonly start around 5% to 10% of the unpaid amount, with additional interest accruing monthly. After a prolonged period of nonpayment, the county can place a tax lien on the property, and eventually the property can be sold at a tax sale to recover the debt.
Courts have consistently held that the owner’s failure to receive a bill is not a defense against penalties or liens. The legal burden falls on you to keep your contact information current with the assessor.
