Tax Lien Interest Rates by State (2026): Where Yields Reach 18–36%

Why the statutory rate is a ceiling, not a promise

Every tax lien state publishes a maximum interest or penalty rate set by statute. That number is the most you can earn — not what you will earn. In "bid-down" states, investors compete by accepting a lower rate, so the winning bid on a desirable property can fall far below the cap. In "premium bid" states, you compete by paying extra cash that usually earns nothing, which dilutes your effective yield. Treat the statutory rate as the top of a range and build your model from there.

The second variable is time. Interest accrues over the redemption period, and a lien that redeems in 60 days earns a fraction of the same rate held for two years. A 20% rate with a six-month redemption and a 12% rate with a three-year redemption are not remotely comparable investments.

The highest-rate states in 2026

A handful of states dominate the top of the yield table. Illinois offers the highest headline penalty — up to 18% per six-month period, which can compound toward an effective 36% annually. Iowa caps at 24% simple, Indiana at up to 25% depending on the redemption window, and Maryland pays up to 20% with an unusually short six-month redemption in some counties. Florida, New Jersey, Ohio, Connecticut, New Hampshire, and Washington, D.C. cluster around an 18% maximum.

• •Illinois — up to 18% per 6 months (penalty structure, not simple annual)
• •Iowa — up to 24% simple annual
• •Indiana — up to 25% penalty depending on redemption timing
• •Maryland — up to 20%, often with a short 6-month redemption
• •Florida, New Jersey, Ohio, Connecticut, D.C. — up to 18% maximum
• •Arizona — 16% maximum, one of the most institutional markets

Penalty states vs. simple-interest states

The word "interest" hides two very different mechanics. In simple-interest states like Iowa and Arizona, your return accrues month by month, so early redemption means a smaller payout. In penalty states like Illinois, Georgia, and Texas (on redeemable deeds), the full penalty is earned the moment the lien is struck — a 20% penalty is 20% whether the owner redeems on day 2 or day 200.

That distinction changes strategy completely. Penalty states reward fast redemptions with enormous annualized yields; simple-interest states reward patience. Knowing which regime you are bidding into tells you whether a quick redemption is a windfall or a disappointment.

How bid-down auctions erode the headline yield

Florida is the classic cautionary tale. The statutory cap is 18%, but in popular counties institutional bidders drive the winning rate down to the low single digits — sometimes 0.25% — on clean, high-value parcels. Florida softens this with a mandatory 5% minimum penalty on redemption, but the lesson holds: competition, not statute, sets your real return.

New Jersey works the same way, then adds premium bidding on top. The result is that the states with the deepest, most liquid markets often deliver the lowest yields, while the fat rates survive on the messier, higher-risk parcels nobody else wants. Chasing the biggest number without reading the parcel is how investors end up owning problems.

Redemption period: the hidden term of your loan

Think of a tax lien as a loan whose term you do not control. The redemption period — six months in parts of Maryland, up to three years in Iowa, two years in Florida — determines how long your capital is tied up and whether you eventually foreclose. Longer periods raise total interest but delay liquidity and increase the odds the property changes hands or deteriorates.

Your annualized return is the rate multiplied by how the redemption actually plays out, minus carrying costs, subsequent-tax payments, and the risk that you end up owning the property through foreclosure. A spreadsheet that ignores redemption timing is not a model — it is a wish.

Rate is nothing without risk-adjusted math

Here is the uncomfortable truth: the state paying 36% is not automatically the best place to invest. A high rate on a parcel with a surviving federal lien, a demolition order, or a flood-zone tear-down can wipe out years of interest in a single closing. The number that matters is yield adjusted for the specific risks attached to the specific parcel.

This is exactly where a disciplined process beats a fat statutory rate. Before you chase 24% in Iowa or 18% in Florida, you need to know what liens survive, whether the IRS holds a 120-day redemption right, and whether the "asset" is even standing. Price the risk first; the rate is only worth collecting if you keep it.
