Average Return on Tax Lien Certificates: What the Statute Pays vs What Investors Keep
About this article: “Marcus” is TaxLienSimple's educational narrator. First-person stories and dollar examples are illustrative scenarios written to explain real tax-sale concepts — they are not the personal trading history of a specific investor. Rate and legal information is sourced separately to official statutes and government records (see About and each guide's citations).
TL;DR
- →There is no single average. The statutory rate is a ceiling set by state law (Iowa 24% fixed, Illinois up to 36%, Florida and New Jersey 18%, Arizona 16%, Kentucky 12%), and the realized return depends on the bid method, how soon the owner redeems, and your costs.
- →In bid-down auctions (Florida, Arizona, New Jersey) competition routinely takes the winning rate to 1 to 5%. In fixed-rate and penalty states the headline rate survives because nobody can bid it away.
- →A $10,000 portfolio at a realized 8% earns about $800 a year before costs; the same money in county-held certificates bought at the full statutory 18% earns $1,800 if the liens stay outstanding a full year and redeem.
- →The full rate is still available without bidding: 5,850 county-held Florida certificates at 18% and thousands of Arizona certificates at 16% are purchasable today, first come first served.
The one-paragraph answer
A tax lien certificate pays the interest or penalty rate written into that state's statute, and only if the owner redeems. Statutory maximums range from 8% a year (Massachusetts tax titles taken after November 2024) to roughly 36% a year (Illinois, where the penalty is up to 18% per six-month period). Across the states we track, the statutory ceilings cluster between 10% and 18%. What an investor actually keeps is lower in every state where the rate is bid down at auction, because the certificate goes to whoever accepts the least. In Florida, Arizona and New Jersey the winning bid on a clean residential parcel is often 1% to 5%. In fixed-rate states (Iowa 24%, Kentucky 12%, Wyoming 15% plus 3%) and penalty states (Illinois, Mississippi, Texas, Georgia) the headline rate is the rate you get, which is why experienced investors rank states by yield protection rather than by the biggest number.
Statutory rates in the states investors ask about most
Every figure below is read from the state statute or the county's published terms, the same sources our county pages cite. "Bid method" is what decides whether the rate survives the auction.
| State | Statutory rate | Bid method | Redemption period | What that means for the realized rate |
|---|---|---|---|---|
| Illinois | Up to 18% per 6-month period (about 36%/yr max) | Penalty bid down | 2 to 2.5 years | Penalty is bid down at sale; 0% to 3% winning bids are common on good parcels |
| Iowa | 24%/yr (2% per month), fixed | Ownership share bid down | 1 year 9 months | Rate is never bid; competition is on the share of the parcel you take |
| Florida | 18%/yr max, 5% minimum unless bid at 0% | Interest bid down | 2 years before deed application | Winning bids of 0.25% to 5% on houses; county-held certificates keep the full 18% |
| New Jersey | 18%/yr max | Interest bid down, then premium | 2 years | Institutional bidders take most liens at 0% and pay premiums |
| Arizona | 16%/yr max | Interest bid down | 3 years | Metro counties bid to 2% to 6%; county-held (state) certificates carry the full 16% |
| Mississippi | 1.5% per month (18%/yr) plus a 5% penalty | Premium bid | 2 years | Rate is fixed; overbid premium is the cost of winning |
| Indiana | 10% if redeemed within 6 months, 15% within a year, plus 5% on overbid | Premium bid | 1 year | Flat penalty, so a quick redemption is the best case |
| Kentucky | 12%/yr simple | Lottery / priority | No fixed term | Rate is fixed; access, not price, is the competition |
| Colorado | 14%/yr for 2025 sales (9 points over the Fed discount rate) | Premium bid | 3 years | Premium is not returned on redemption |
| Maryland | Up to 18%/yr non-owner-occupied (Baltimore City), 6% to 12% elsewhere | Premium bid | 6 months minimum before foreclosure | High-bid premium is the competition |
| Texas | 25% flat within 180 days, 50% in year two (redeemable deed) | Highest bid on the deed | 180 days or 2 years (homestead) | Flat penalty on your full bid, the strongest yield protection in the country |
| Georgia | 20% flat on redemption (redeemable deed) | Highest bid on the deed | 12 months | Flat penalty; you own the deed if not redeemed |
| Wyoming | 15%/yr simple plus a 3% penalty | Lottery / rotation | 4 years | Fixed; access is by draw |
| West Virginia | 1% per month (12%/yr) | Premium bid | About 18 months | Fixed rate on the tax amount |
| South Dakota | 10%/yr max | Interest bid down | 3 to 4 years | Small auctions, usually near the maximum |
What a $10,000 portfolio actually earns
Assume ten certificates of $1,000, every one redeems, and you spend $150 on registration, research and recording across the year. The realized rate is the whole story.
| Scenario | Rate earned | Held (months) | Interest | Net after $150 costs | Return on $10,000 |
|---|---|---|---|---|---|
| Crowded Florida online sale | 2% | 12 | $200 | $50 | 0.5% |
| Florida county-held certificates bought after the sale | 18% | 12 | $1,800 | $1,650 | 16.5% |
| Florida county-held, redeemed early | 18% (5% minimum applies) | 3 | $500 | $350 | 3.5% |
| Iowa fixed 24% | 24% | 12 | $2,400 | $2,250 | 22.5% |
| Indiana, redeemed in month 4 | 10% flat | 4 | $1,000 | $850 | 8.5% in four months (about 25% annualized) |
| Texas redeemable deed, redeemed in month 5 | 25% flat | 5 | $2,500 | $2,350 | 23.5% in five months |
| Illinois, bid down to 1% per period | 1% per 6 months | 12 | $200 | $50 | 0.5% |
What cuts the return below the statute
- Bid-down competition: the largest single factor. Institutional funds bid Florida and New Jersey residential liens to 0% to 1% and profit on volume and deed applications, not interest. - Early redemption: interest accrues only while the lien is outstanding. A 16% lien redeemed in six weeks pays 16% annualized on six weeks, which is small money against fixed costs. Florida's 5% minimum and the flat penalties in Texas, Georgia, Indiana and Mississippi exist to protect you from exactly this. - Premiums that do not come back: in premium-bid states (Colorado, Mississippi, Maryland, West Virginia) the overbid is usually not repaid with interest, so it is a direct reduction of yield. - Idle capital: deposits parked before the sale and money sitting between redemptions and the next auction earn nothing. - Subsequent taxes: in many states you must pay the next year's taxes to protect the lien. They earn interest too, but they tie up more capital. - Non-redeeming worthless parcels: a lien on a drainage strip or a condemned structure may never redeem and may cost more in foreclosure than it is worth. This is the loss case, and it is avoidable with due diligence.
Where the full statutory rate is still available today
Certificates that receive no bid at the annual sale are struck to the county at the maximum rate and sold afterwards, first come first served, at the tax amount plus accrued interest and fees. No auction, no bidding down. As of September 17, 2026, TaxLienSimple tracks 5,850 county-held Florida certificates at 18% across 25 counties on LienHub (Santa Rosa 2,558, Volusia 1,841, Miami-Dade 290, Sarasota 230, Alachua 229 among them) and thousands of Arizona certificates at 16% on the county sites for Pima, Pinal and Maricopa. The catch is selection: these are the parcels the bidders passed on, so vacant land, odd lots and low-value improvements dominate, and the same due diligence applies. The county pages list every one with the purchase amount and the assessed value so you can filter before you buy.
How to read any return claim you see online
Ask four questions. Is the number a statutory ceiling or a realized rate? Is the rate annual or flat per period? Does the example assume a full-year hold? Does it net out costs? Most "earn 18% guaranteed" pages fail all four. The county sale terms and the statute are the only sources that cannot exaggerate, which is why every rate on this site links to one.
Frequently Asked Questions
What is the average interest rate on a tax lien certificate?↓
Statutory maximums cluster between 10% and 18% a year across lien states, with Iowa at 24% fixed and Illinois up to about 36% a year. Realized rates in bid-down auctions (Florida, Arizona, New Jersey) are commonly 1% to 5%. There is no national average because each state's law and bid method differ.
Which states pay the highest tax lien interest?↓
By statutory maximum: Illinois (up to 18% per six-month period), Iowa (24% fixed), then Florida, New Jersey, Mississippi and Maryland at 18%. For yield that survives the auction, fixed-rate and penalty states (Iowa, Texas at 25% flat, Georgia at 20% flat, Mississippi, Indiana) rank higher than bid-down states.
Can I get the full 18% in Florida?↓
Yes, on county-held certificates: liens that received no bid at the June sale are held by the county at 18% and sold year-round on LienHub at the tax amount plus accrued interest. At the auction itself, competitive parcels are usually bid down to 5% or less.
How long until I get paid on a tax lien?↓
When the owner redeems, which can be days or years. Most certificates that redeem do so within the first year. If the owner never redeems you must apply for a deed or foreclose after the state's redemption period (1 to 4 years depending on the state), and interest stops when the deed issues.
Are tax lien returns guaranteed?↓
The rate is set by statute, but payment depends on redemption. If the property is worthless and nobody redeems, the certificate can expire or cost more to foreclose than it returns. Returns are statutory, not guaranteed.
From real investor threads
What people get wrong about tax lien returns, from Reddit and BiggerPockets threads
The statutory rate is the number in every advertisement. These are the ways real investors found out what they actually earned, each one linked to the thread where they said it.
Is the 18% tax lien rate real? In a bid-down auction it went to zero and below
The mistake: Turning up to a New Jersey or Florida online sale expecting the statutory maximum. On liens with a mortgage behind them, banks and funds bid the rate to nothing to protect their position.
“0%. Negative 1%. Negative 2%. These people were now paying for the privilege of owning the tax lien. This wasn't an investment anymore.”Empathic Finance, first-person account of a Camden County NJ sale: read the thread
How to avoid it: Check what last year's winning rates were in that county before you register. In Florida the 5% minimum on redemption is the floor that makes a 0.25% bid survivable; in New Jersey the money is in subsequent taxes at 18%, not the auction rate. If you want the full statutory rate without bidding, county-held certificates carry it.

The mistake: Quoting the annual rate as the return. Interest accrues only while the lien is outstanding, and most liens redeem fast.
“If your lien gets redeemed in one month, you are only getting 1/12 of 4%. (95% liens will be redeemed)”BiggerPockets forum, Coconino County AZ results thread: read the thread
How to avoid it: Run the redemption month, not just the rate, before you bid. Penalty states (Texas 25% flat, Georgia 20%, Indiana 10% to 15%) and Florida's 5% minimum exist precisely because early redemption guts a per-annum rate.

The mistake: Buying liens so small that the treasurer's flat administrative fee is larger than a year of interest.

How to avoid it: Set a minimum lien size per county so the fee schedule cannot eat the yield. Read the fee page before the sale; it is usually one paragraph.

The mistake: Paying a premium that implies an 18-month breakeven in a county where most liens redeem inside a year.
“I won ~$100k worth in the 4-9 month range, in the end I felt lucky to break even.”Reddit r/realestateinvesting (u/CRE_Energy): read the thread
How to avoid it: Compute the breakeven month for any premium before bidding, and walk when it is longer than the typical redemption in that county. Premiums are not returned with interest in most premium states.
Find the premium that leaves your target return intact →"The rate is mandated by law" is true; who pays it is the question
The mistake: Treating the statute as a guarantee of payment rather than a guarantee of the rate if payment comes.
“It is true, % is mandated by law. But like a deadbeat renter, someone has to pay.”Reddit r/realestateinvesting (u/Away-Opinion-8540): read the thread
How to avoid it: Underwrite the parcel, not the rate: assessed value against the lien, a structure that can burn, prior-year certificates outstanding. A lien on a worthless lot pays the statute on nothing.
