The Cochise County tax lien map is an interactive, nightly-updated view of every parcel in the county that carries a delinquent property tax lien. You reach it from the Treasurer’s page on the county website, under the back tax lien information section. Whether you’re checking your own property or researching liens to bid on, the map works alongside the Treasurer’s Parcel Inquiry tool, and the two together are what you’ll actually use.1Cochise County, AZ.

Questions about the map itself go to the Treasurer’s office, not the GIS department. GIS maintains the mapping software but does not handle tax lien data.
Opening the Map
The map runs on a GIS interface: a zoomable view of the county with parcel boundaries drawn over aerial imagery or a plain base map. Scroll to zoom, drag to pan, click a parcel for its details. You can toggle between satellite imagery and a clean parcel-line view. Satellite is useful for rural parcels where you want to see terrain, structures, and road access before drawing conclusions from an address alone. The parcel-line view is easier to read when comparing neighboring lots.
Looking Up a Parcel
The fastest lookup is by Assessor’s Parcel Number (APN), the unique code assigned to every piece of land in the county. If you don’t have the APN, search the property’s street address through the Assessor’s website to find it, then return to the Treasurer’s Parcel Inquiry to pull the tax information.2Cochise County Treasurer.

Parcel Inquiry also accepts owner name or mailing address searches when you don’t have a parcel number.3Cochise County Treasurer. Parcel Search There is no fuzzy matching. A misspelled name or a transposed digit returns nothing or the wrong parcel, so double-check what you type.
What You’ll See on a Parcel
Selecting a parcel, whether on the map or through Parcel Inquiry, returns the information tied to that land:
- Legal description used in deeds and title documents, referencing lot numbers, subdivision names, or metes and bounds.
- Assessed valuation for tax purposes, often with a history showing how the value has changed.
- Tax payment status: current, delinquent, or subject to a lien certificate held by a third-party purchaser.
- Parcel boundaries drawn on the map, which you can view against satellite imagery.
What the Map Doesn’t Show
The map shows county tax liens. It does not necessarily show federal tax liens, mechanic’s liens, or judgment liens recorded with the county recorder. If you need the full picture of what is attached to a title, that requires a title search through the recorder’s office, not the tax lien map.
Timing is the other limit. The nightly update means there is always a short lag between a payment or a sale and the change appearing online. For anything time-sensitive, call the Treasurer’s office to confirm what you see on screen. The online tools are research aids, not a substitute for the office that keeps the records.
Using the Map to Research Liens for Purchase
Cochise County requires a completed Bidder Application before you can participate in a lien auction.1Cochise County, AZ. Treasurer – Section: Back Tax Lien Information The map tells you which liens exist. It does not give you the full financial picture on its own, which is why the county recommends running each parcel through Parcel Inquiry before bidding.
Before you bid, confirm the total delinquent taxes owed, whether the parcel carries multiple years of unpaid taxes, and the assessed value of the land underneath. A lien on a parcel worth less than the delinquent taxes is a poor investment even at a strong interest rate, because you may not recover your outlay if the owner walks away.
The Treasurer’s office is the definitive source for current payoff amounts and auction schedules. Contact the office directly before committing money based on what the online tools display.
If You’re a Property Owner Who Finds a Lien
If the map or Parcel Inquiry shows a lien on your property, Arizona gives you three years from the date of the tax lien sale to redeem it by paying the full amount owed plus accrued interest. You can still redeem after that window as long as a treasurer’s deed has not been delivered to the lien holder and the property has not been sold for excess proceeds.4Arizona Legislature. Arizona Revised Statutes 42-18152 – Redemption of Property The three-year mark is the earliest an investor can begin foreclosure, not an automatic transfer of ownership. Interest accrues the whole time, so the sooner you act, the less it costs to clear.
