The IRS 120-Day Redemption Right: What Every Tax Deed Investor Must Know Before Bidding on a Property With a Federal Tax Lien

Why the IRS Gets a Second Bite at the Apple

When a property owner owes the federal government back taxes, the IRS files a Notice of Federal Tax Lien (NFTL) in the county recorder's office. That filing gives the lien priority against subsequent purchasers and encumbrancers who search the record. Under the Internal Revenue Code, when real property encumbered by a federal tax lien is sold through a nonjudicial or judicial foreclosure — including a county tax deed sale — the IRS retains a right to step in after the auction and redeem that property at the winning bid price. This right exists independently of any state redemption statutes. It does not expire because a state's redemption window is shorter. It runs for 120 days from the date of the sale, and it applies whether the IRS lien was wiped out by the sale or not.

The mechanism is rooted in federal supremacy. State tax foreclosure proceedings extinguish many junior liens, but Congress wrote a specific carve-out giving the IRS time to evaluate whether a property was sold for less than its market value relative to the federal tax debt it could recover. In practice, the IRS rarely exercises this right — but it does exercise it, and the possibility alone creates measurable risk that every investor bidding on a property with a recorded NFTL must price in before the auction.

How the 120-Day Clock Works in Practice

The 120-day period begins on the date of sale. During that window, the IRS can redeem by paying the winning bidder the amount paid at auction plus interest at the rate set by the IRS for underpayments, calculated from the sale date. The IRS does not reimburse any improvements you make to the property during those 120 days beyond what is specifically allowed under the statute, which creates a second layer of risk: you should not invest significant capital in renovation or resale preparation until the redemption window has fully closed.

Notice requirements matter here. The IRS is entitled to notice of the sale before it happens. If proper notice is not delivered to the IRS, the 120-day clock may not start running at all, meaning the redemption right could linger well beyond 120 days from auction. Verifying that the county or conducting authority has issued proper notice to the IRS is part of thorough pre-bid due diligence — not something to assume happened correctly.

• The IRS redemption price is generally the amount you paid at auction plus accrued interest.
• Improvements made during the 120-day window are generally not reimbursable beyond a narrow statutory allowance.
• If proper IRS notice was not given, the 120-day window may not have been triggered.
• The right applies even when the federal lien was otherwise extinguished by the foreclosure.

How to Identify Properties at Risk Before You Bid

Finding a recorded NFTL requires searching beyond just county property tax records. Federal tax liens are filed in the county where the taxpayer resides or where the property is located, depending on state rules, and they appear in the county recorder's or clerk's land records — the same index you use for deeds and mortgages. A thorough title search that includes a search of federal tax lien filings under the property owner's name is essential. Many investors run abbreviated searches before a tax deed auction and miss NFTLs entirely because they focus only on recorded deeds and junior mortgages.

You should also check the IRS NFTL filing against the property address and the owner's legal name as it appears in the assessor's records. Common name variations and middle initial discrepancies can cause liens to appear under a slightly different spelling. A licensed title professional who understands NFTL indexing conventions can help you confirm whether a lien that appears in the index actually attaches to the parcel you are evaluating. Do not assume the auction notice or the county's lien runsheet has surfaced every NFTL — county staff are not responsible for identifying federal liens on your behalf.

• Search recorder records under the property owner's exact legal name and common variations.
• Check both the county of property location and, where applicable, the county of debtor residence.
• Use a licensed title professional familiar with NFTL indexing to review ambiguous results.
• Do not rely solely on the auction package or county lien summary to identify federal liens.

What Happens to Your Plans If the IRS Redeems

If the IRS exercises its redemption right, you receive your purchase price back plus interest, and title reverts to the United States. The IRS then owns the property and will typically offer it for sale through its own disposition process. You lose any carrying costs, transaction fees, opportunity cost, and time invested in the deal. If you have already entered into a contract to resell the property or made financial commitments based on owning it, you bear those losses without recourse.

This outcome is not common, but it is also not theoretical. Investors who buy properties at auction with recorded NFTLs without accounting for this risk are making an unpriced bet. The smarter approach is to factor the 120-day hold period into your underwriting: assume you cannot market or resell the property for at least 120 days after purchase, and model what that carrying cost does to your return. If the numbers still work under that constraint, you have a defensible position. If they do not, the risk premium demanded by that IRS window may not be worth it.

How to Evaluate This Risk Systematically Before Every Auction

A disciplined pre-bid process for any tax deed auction should include at minimum: a search for recorded NFTLs under the owner's name, a review of whether the county has sent proper IRS notice as required under the Internal Revenue Code, and a clear-eyed assessment of whether the property's likely after-repair value exceeds your all-in cost including a 120-day hold. This is not just a legal checkbox — it is the foundation of rational bidding.

Tools like TaxDeedIQ are designed to help investors surface risk factors like federal liens, IRS redemption exposure, and other title hazards before a bid is placed, assigning each property a Safety Score that reflects the cumulative weight of these issues. Whether you use a platform or conduct manual research, the discipline is the same: understand every encumbrance, every redemption right, and every potential claim against the property before you commit capital. The IRS redemption window is one of the less visible risks in tax deed investing — but it is one of the most consequential if you encounter it without preparation.

Always verify findings with the county recorder, a licensed title professional, and a qualified real estate attorney in the relevant state. Statutes change and individual property circumstances vary in ways that general guidance cannot fully capture.

• Confirm NFTL search is part of every pre-auction title review, not just post-auction.
• Review auction notice documentation to verify IRS was properly notified before the sale.
• Model a minimum 120-day hold into your carrying cost calculations for any NFTL-encumbered property.
• Consult a real estate attorney in the relevant state before bidding on any property with a recorded federal lien.
