Avoiding Tax Sale Scams: Spot Fraud and Verify a Real Lien

Tax sales draw fraud from two directions. Former owners who just lost a property are chased for the surplus money the sale leaves behind, and new investors are sold fake liens, bogus lists, and guaranteed-return courses. The good news is that almost every one of these schemes breaks the same rule: it asks you to trust a stranger instead of the public record. This guide walks the common scams on both sides, the red flags they share, and the simple habit that defeats most of them, which is to verify everything at the county source. None of this is legal advice, and the specific rules vary by state.

Deed theft and forged liens

The most damaging scam does not involve a tax sale at all until the end. Criminals forge or fraudulently record a deed, often a quitclaim, to transfer a property out of the true owner's name, then try to sell it, mortgage it, or rent it out. The real owner has to go to court to reclaim it.

Tax-delinquent and vacant parcels are the favorite target. In a 2026 public service announcement, the FBI's Internet Crime Complaint Center described a scheme in which criminals impersonate the owners of vacant parcels, using stolen personal information, counterfeit IDs, and fake email and phone numbers to push through a sale before anyone notices. The absentee, no-mortgage profile that fits so much rural tax-deed land is exactly what they look for.

Two facts protect you. First, per the FTC, there is no way to lock your title, and paid title-lock products do not prevent a fraudulent deed from being recorded. Second, the real safeguards are free: many county recorders run a recording-notification program that emails you whenever a document is filed under your name, and the FBI recommends enrolling.

Surplus and overage recovery scams

When a property sells at a tax sale for more than the taxes owed, the extra money, the surplus or overage, does not belong to the county. In Tyler v. Hennepin County (2023), a unanimous Supreme Court held that keeping more than the tax debt violates the Fifth Amendment Takings Clause, so that surplus is generally the former owner's to claim. That real, claimable money is exactly what recovery scammers chase.

The pitch arrives by letter or a knock on the door, offering to recover funds you may not even know exist, for a large cut. The New Jersey Attorney General warns that these outfits sometimes charge up to 75 percent of the surplus, and points out the counter-fact: an owner can usually apply directly, often for less than 100 dollars and sometimes without an attorney, by contacting the county office that holds the money. If someone wants a big fee to claim money that is already yours, slow down and call the county first. Our guide to tax deed surplus funds covers who is actually entitled to the overbid.

Fake government, free-list, and guaranteed-return scams

New investors get a different set of pitches. Some are fake-government letters, which the CFPB flags for using designs, emblems, logos, or names that look or sound like a real agency, along with pressure to act immediately. Others sell overpriced or bogus property lists, or offer to privately sell you a tax lien outside any auction, which a legitimate lien never is.

Then there are the courses. A cheap introductory seminar upsells to a five-figure mentorship, sold on the promise of guaranteed, government-backed returns. The FTC has taken real action here: in a case that resolved with refunds in 2024, it sued a real-estate investment training operation over false earnings promises, won a permanent ban on selling wealth-creation products, and returned more than 10 million dollars to consumers. Tax-lien and tax-deed returns are never guaranteed. They depend on redemption, the property's real value, and the statutory process, and you can lose money, as our guide to realistic tax lien returns explains.

How to verify a real tax lien or tax deed

Every legitimate tax lien and tax deed comes from county government through a public, statutory process. The tax collector or treasurer runs the certificate sale; the clerk of court or county runs the tax-deed auction after the statutory redemption period; the sale is publicly noticed and conducted by the county or its official online platform. No stranger can privately sell you a valid tax lien outside that process.

To confirm any specific lien, deed, or auction, go to the source of record rather than a third party:

• Recorded deeds and liens: the County Recorder or Register of Deeds.
• Certificate status: the County Tax Collector or Treasurer.
• Tax-deed cases: the Clerk of Court.

Type the county's official .gov address yourself instead of following a link from an email, cross-check the parcel ID and legal description, and confirm any auction site through the county's own page. Our guide on how to find tax sale property lists points to the official sources for each state.

The red-flags checklist

Any one of these is a reason to stop and verify:

• An upfront fee to claim money or guarantee a result.
• Urgency: act now, today only, before someone else does.
• Government impersonation: official-looking logos or agency-sounding names on mail or email.
• Guaranteed returns or government-backed certain profit.
• A private, off-auction offer to sell you a tax lien or certificate.
• Pressure to sign over your title or to stop paying your lender.
• Payment by wire, gift card, or cryptocurrency, or to an out-of-state account.

Protect yourself, and where to report

Enroll in your county recorder's free recording-alert program, check your own property records now and then, and carry title insurance with forgery coverage on any purchase. When something looks wrong, report it to the right channel: identity or deed fraud to the FTC (IdentityTheft.gov and ReportFraud.ftc.gov) and the FBI (ic3.gov); mortgage or foreclosure-relief scams to the CFPB; surplus scams and general fraud to your state attorney general; and a forged recording to your county recorder and local police. Reporting protects the next person as much as it helps you.

Bidding at a real sale still carries real risk, which is a separate topic from fraud; see the risks of tax lien and tax deed investing for that side. On the fraud side, the rule is simpler: verify at the county, and never pay a stranger for access to the public record.
