How to Find Tax Lien and Tax Deed Auctions Near You
There's no single national database of every tax sale in the country — auctions are run county by county (sometimes municipality by municipality), and there's no requirement that they all list in the same place. Finding real, current auctions means knowing where to look, which mostly comes down to three sources.
1. The county treasurer or tax collector's website
This is the primary source, every time. Whatever a third-party site tells you, the county treasurer's, tax collector's, or auditor's office (the exact title varies by state) is the legal notice-giver, and their website is where the actual, binding auction list, deposit requirements, and rules live. Search "[county name] [state] treasurer tax sale" or "[county] tax collector delinquent tax sale" — most counties publish a PDF or webpage listing upcoming sale dates months in advance.
2. The auction platform the county actually uses
A large and growing share of counties run their sales through third-party online auction platforms rather than an in-person courthouse-steps sale. The most common ones:
- RealAuction — widely used across Florida, and by counties in several other states for both lien and deed sales.
- GovEase — common across a number of Southern and Midwestern counties.
- Bid4Assets — used for many tax-defaulted property (deed) sales, including several California counties.
- SRI Inc. — runs auctions for a number of Indiana and Colorado counties, among others.
- Zeus Auction Systems / MNBid — used by some Midwestern counties, including parts of Minnesota.
The county's own website will name which platform (if any) it uses — that's always the more reliable path than guessing which platform to search first. Registering on one of these platforms with a refundable deposit is standard before you can even see full parcel lists for that county's sale.
3. State-level resources
A few state revenue or treasury departments maintain a statewide list or index linking out to individual county sales — useful as a starting point, though county-level pages are still the authoritative source for details. See our state-by-state overview for how each state structures its sale, and Market Pulse for specific dated county auctions we've verified directly against government sources.
Red flags on third-party listing sites
Plenty of sites aggregate tax sale listings and charge for "premium" property lists — some are legitimate research tools, others recycle stale data from a prior year's sale. Before trusting any list that isn't the county's own page: check the sale date against the current year, confirm the parcel numbers are still listed as delinquent on the county's own GIS or assessor site, and never pay for a list you can't verify independently against a government source first.
