Tax sale lists
Tax sale lists: find current auctions and verify them
The authoritative tax-sale list is the current notice published by the responsible county or its formally identified auction provider. A research platform can organize discovery, but the official source decides whether a sale is current.
Prepared by TaxLienSimple Research Team. Reviewed July 28, 2026 against the official-source workflow described in our verification policy.
This page explains a general process. State and county guides identify the responsible office and point to the current official source for each jurisdiction.
Where official lists appear
Counties may publish notices through a tax collector, treasurer, clerk, sheriff, court, newspaper of record, or auction vendor. The location varies by state and county.
Start with the state guide, then follow the official county source. Avoid treating a third-party list as a final confirmation.
How to assess freshness
Check posted date, sale date, source link, and whether the record says active, historical, cancelled, or timing unassigned.
A procedure page can be valuable research without being a current auction. Do not remove a legitimate record solely because timing is not assigned; label it correctly and continue verification.
Build a repeatable watchlist
Save the jurisdiction, official link, sale type, likely schedule, registration requirements, and reminders. When a property is available, connect it to research notes and a pre-set bid limit.
This keeps auction-day choices from becoming a scramble across unrelated tabs.

A narrated walkthrough: find tax liens by county, read the Research Score, risk flags and sources, set your maximum bid and save a Deal Radar.
Read the transcript
If you came here for tax liens, start in Property Research and choose Tax Lien.
Liens without a set sale date sit under Timing not assigned yet. That includes over the counter liens you can buy now, with no auction.
Pick a state and a county. I'll use Maricopa County, Arizona.
Tick Mapped only to see each lien on the map, and switch to aerial imagery to look at the property from above.
Open a lien to see the full research.
The Research Score grades it from A to D, out of one hundred, and shows where the points come from.
Estimated value and confidence gives you a value range, and tells you how far to trust it. It's a starting point, not an appraisal.
Risk flags come up before you buy: whether it's still available, liens that may survive, and a source that may be out of date. Open one to see what to check.
The due diligence checklist shows the lien to value ratio and the back taxes, and what you still need to verify yourself.
Sources and freshness links every fact back to the county's own record.
Then calculate your maximum bid. You get a comfortable range, a caution range, and the price where you should stop.
Back in Research, mark it as a bid candidate, and add private notes that only you can see.
Save your search as a Deal Radar, and new matches come to you by email.
That's tax liens: from a county to a lien worth buying, with every fact sourced to the county.

Finding tax lien sales: auctions, OTC, and calendars
Real tax-lien sales are published by the county treasurer or tax collector, not by a marketing calendar, start at the source.
Use official sources next
Browse the statute-oriented state guides, then verify a current notice through the linked county or auction source. Use the calculator to set a disciplined limit, not to replace title or legal review.
