Tax Lien & Tax Deed Glossary

Plain-English definitions of the terms that come up in tax lien, tax deed, and redeemable-deed investing. Rules vary by state; where a term is state-specific we say so and link the relevant guide. This is educational information, not legal or investment advice.

Tax sale

The process by which a county or municipality collects delinquent property taxes by selling either a lien against the property or the property itself (a deed) at public auction. The three broad systems are tax lien, tax deed, and redeemable (hybrid) deed.

Tax lien certificate

A document a government sells to an investor representing the delinquent taxes owed on a property, plus the right to collect that amount back with statutory interest or a penalty when the owner redeems. Buying a certificate does not transfer ownership of the property; it buys the government's claim. Tax lien investing guide →

Tax deed

A conveyance that transfers ownership of a property to the buyer at a tax sale because the taxes went unpaid. In a pure tax deed state there is no post-sale redemption right, so the buyer takes title subject only to the sale-confirmation and title-clearing process.

Redeemable tax deed

A hybrid instrument: the buyer receives a deed at the sale, but the former owner keeps a right to redeem for a set period by repaying the purchase price plus a statutory penalty or interest. If no redemption occurs, the buyer's ownership becomes absolute. Georgia, Texas, and Tennessee are redeemable-deed states. Texas redeemable-deed guide →

Redemption period

The window during which a delinquent owner (or another interested party) may reclaim the property or extinguish the lien by paying what is owed plus interest, penalty, and costs. Length varies widely by state and sometimes by property type, and the clock's start event (sale, recording, or certificate issue) also varies.

Right of redemption

The legal right of an owner, lienholder, or heir to pay the delinquent taxes plus statutory charges and recover the property or clear the lien before that right is cut off. It is the core protection for property owners in the tax-sale system.

Redemption

The act of exercising the right of redemption, paying the certificate holder or the county the taxes, interest, penalty, and costs owed. For a lien investor, redemption is the normal, desired exit: you get your capital back plus the statutory return.

Bid-down interest

An auction format used in many lien states where bidding starts at the statutory maximum interest rate and competing investors accept progressively lower rates; the lowest rate wins the lien. Arizona (16% ceiling) and Florida (18% ceiling) use bid-down formats, which is why winning rates in competitive counties can fall to low single digits. Arizona bid-down guide →

Premium bid

An auction format where investors bid the price up above the base amount owed. The excess paid over the taxes is the premium. Depending on the state, the premium may earn no interest and may or may not be returned at redemption, so overbidding directly erodes yield.

Penalty bid

A return structured as a flat percentage of the amount invested rather than interest that accrues over time. A penalty is earned in full the moment the owner redeems, so a quick redemption on a penalty-state lien can produce a very high annualized return. Georgia's 20% first-year figure is a penalty, not annual interest. Georgia penalty guide →

Over-the-counter (OTC)

The purchase of liens or deeds that went unsold at auction directly from the county, typically at the full statutory rate and without competitive bidding. OTC (also called 'county-held' or 'assignment' inventory) lets smaller investors avoid rate compression, but unsold parcels warrant extra due diligence.

Struck-off

A parcel that received no acceptable bid at a tax sale and was therefore 'struck off' to the taxing entity (the county, city, or state), which then holds it for later resale, often over the counter. Struck-off lists are a common source of OTC inventory.

Certificate of delinquency

In some states, the recorded instrument evidencing unpaid property taxes that becomes the lien sold to or enforced by a third-party purchaser. Kentucky, for example, sells certificates of delinquency to investors who may later pursue collection. Kentucky guide →

Certificate of purchase (CP)

The document issued to the winning bidder at a lien sale in some states (notably Arizona), evidencing the lien purchased and the rate bid. Holding a CP entitles the investor to redemption proceeds and, after the statutory wait, the right to begin foreclosure.

Subsequent taxes (subs)

Property taxes that come due after an investor already holds the lien. In many states the certificate holder may pay these 'subs' and add them to the redemption amount, often at the same statutory rate, a way to deploy more capital at a known return without a new auction.

Assignment

The transfer of a tax lien certificate or a county-held lien from one party to another. States that permit assignment let investors buy county-held certificates over the counter, or sell certificates they already hold to another investor.

Lien priority

The order in which competing claims against a property are paid from sale proceeds. Property tax liens generally hold a superior (first) position ahead of mortgages and most other liens, which is a central reason tax liens are considered well-secured.

Super-priority lien

A lien that by statute outranks even earlier-recorded liens, including first mortgages. Ad valorem property tax liens are typically super-priority, meaning they survive and take precedence over most other encumbrances at a tax sale.

Ad valorem tax

A tax calculated 'according to value'for real estate, the property tax assessed as a percentage of the property's assessed value. Delinquent ad valorem taxes are what tax lien and tax deed sales collect.

Quiet title action

A court lawsuit that resolves competing claims and establishes clear, marketable title in the plaintiff's name. Tax deed buyers frequently must file a quiet title action (or obtain a similar judgment) before a title insurer will insure the property for resale or financing.

Tax-sale overage / surplus funds

Money left over when a property sells at a tax sale for more than the taxes, penalties, and costs owed. These excess proceeds generally belong to the former owner or junior lienholders, who must usually file a claim to recover them; unclaimed overages are a distinct niche from lien or deed investing.

Upset sale

In Pennsylvania and some other states, the first-stage tax sale where the property is sold subject to existing liens and mortgages, with a minimum ('upset') price covering taxes and costs. Properties not sold at the upset sale may later move to a judicial 'free and clear' sale.

Judicial foreclosure

Enforcement of a tax lien or deed through a court proceeding, ending in a court-ordered sale or judgment. It is slower and costlier than an administrative process but produces a cleaner, court-backed title. Many lien states require a judicial foreclosure to convert an unredeemed lien into ownership.

Administrative foreclosure

Enforcement through a non-court process handled by a county official, such as applying for a treasurer's or tax deed after the redemption period expires. It is faster and cheaper than judicial foreclosure but the resulting title may need additional clearing before it is insurable.

Lis pendens

Latin for 'suit pending'a recorded notice that litigation affecting title to a property is underway. Filing a lis pendens when starting a tax foreclosure or quiet title action puts the world on notice and binds later purchasers to the outcome.

Treasurer's deed

The deed issued by a county treasurer to a lien holder who has satisfied the statutory waiting period and notice requirements, conveying the property after the owner failed to redeem. The term is used in states such as Colorado, where recent law changed the deed-issuance process. Colorado guide →

Encumbrance

Any claim, lien, mortgage, easement, or restriction attached to a property that may affect its title or value. Tax sales extinguish some encumbrances and leave others (such as certain government liens or easements) in place, which is why title research is essential.

Due diligence

The research an investor performs before bidding: confirming the parcel, assessed and market value, condition, occupancy, other liens, code violations, and whether the taxing authority's sale terms are current. Skipping due diligence is the most common cause of tax-sale losses. Due-diligence checklist →

Face value (lien amount)

The base amount of delinquent taxes, penalties, and costs represented by a lien certificate. Statutory interest usually accrues on the face value only, not on any premium paid above it, which is a key distinction in premium-bid states.

Effective yield

The actual annualized return an investor realizes after accounting for the rate won, any premium paid that earns nothing, the time to redemption, and costs. Because of bid-down and premium dynamics, effective yield is often well below a state's headline maximum rate.

Tax certificate sale vs. tax deed sale

A certificate (lien) sale transfers only the government's claim and the right to a return, leaving the owner in possession; a deed sale transfers the property itself. Knowing which system a state uses determines whether you are buying income or real estate. Lien vs deed explained →

Statutory interest rate

The maximum rate of return a state sets by law for tax lien redemptions. It is a ceiling, not a guarantee: in bid-down states competition lowers the rate actually earned, while in fixed-rate states every certificate carries the statutory rate.

Cloud on title

Any recorded claim, defect, or irregularity that makes ownership uncertain and title unmarketable. Tax deeds commonly carry a cloud on title until a quiet title action or statutory confirmation removes it, which is why insurers often require that step before closing.

Notice (take-notice / barment)

The formal, statutorily required communication a lien or deed holder must send to the owner and other interested parties before foreclosing or barring redemption. Defective or missing notice is a frequent reason tax-sale titles are voided, so strict compliance is critical.
