States with the Best Tax Lien Interest Rates (2026)

Not all tax lien states are created equal. Interest rates range from 8% to 36% depending on where you invest, and the rules around redemption, bidding, and online access vary wildly. If you're choosing where to invest in tax lien certificates in 2026, this breakdown will help you compare your options.

Top States by Maximum Interest Rate

Here's how the states stack up, ranked by their maximum statutory interest rate:

Illinois — Up to 36% Annually

Illinois offers the highest potential returns in the country. The statutory rate is 18% per 6 month period, which works out to 36% annualized. Tax sales happen at the county level, typically in November or December.

The catch: Illinois uses a "penalty bid" system where investors bid the percentage of the property they're willing to forfeit if the owner redeems. It's a unique system that takes some getting used to. Cook County (Chicago) is extremely competitive.

Iowa — 24% Annually

Iowa charges 2% per month on delinquent taxes, adding up to 24% per year. Tax sales happen in June each year at the county level. Iowa liens can be purchased at the county treasurer's office, and many counties offer over-the-counter liens that didn't sell at auction.

The redemption period is 1 year and 9 months. Iowa is popular with experienced investors because of the high rate and relatively straightforward process.

New Jersey — 18% Annually

New Jersey caps its tax lien interest rate at 18% per year. Sales happen annually, typically in October or November. Many New Jersey counties now use online bidding platforms.

Competition can be fierce in densely populated counties. At competitive auctions, investors bid down the interest rate... sometimes all the way to 0%... and then bid a premium above the lien amount. This shifts the game from earning interest to hoping for foreclosure.

Florida — 18% Annually

Florida is one of the most popular states for tax lien investing. The maximum rate is 18% per year, and auctions use a bid-down-the-interest system. All 67 counties hold tax certificate sales, typically in late May or June.

Most Florida tax sales are conducted online through RealAuction. The 2 year redemption period means your capital is locked up for a while. In competitive counties like Miami-Dade and Broward, winning rates can drop to 0.25%.

Rural Florida counties tend to offer better rates. Check our Florida county pages for specific tax office contacts.

Arizona — 16% Annually

Arizona offers a flat 16% annual rate on tax lien certificates. Sales happen in February at the county level. Maricopa County (Phoenix metro) is one of the largest tax lien sales in the country, with thousands of parcels available.

Arizona uses a bid-down system where investors bid down the interest rate from 16%. The 3 year redemption period is longer than most states. Online bidding is available in most counties.

Indiana — 10% to 15% Annually

Indiana interest rates vary based on the property value. Liens on properties assessed under $150,000 earn 10% per year. Liens on properties over $150,000 earn 15%. Sales happen annually, typically in the fall.

Indiana also has a relatively short 1 year redemption period for most properties, which means your capital isn't locked up as long. Many counties use online platforms.

South Carolina — 12% Annually

South Carolina offers a flat 12% per year (3% per quarter plus 3% per quarter). Tax sales happen in November or December. The redemption period is 1 year.

South Carolina is less well-known among tax lien investors, which means less competition in many counties. This can work in your favor if you're willing to research smaller markets.

Maryland — Up to 24% (Varies by Jurisdiction)

Maryland is interesting because rates vary by county. Some jurisdictions charge up to 24% on the delinquent amount, while others are lower. Baltimore City is one of the most active tax sale markets in the state.

Maryland's system has some complexity... different rules for different jurisdictions and a high bid premium system in some areas. Do your homework on the specific county you're targeting.

States with Online Bidding

A growing number of states offer online tax lien auctions, which is a game-changer for investors who want to invest outside their home state:

›Florida — Nearly all counties use RealAuction
›Arizona — Most counties including Maricopa use online platforms
›Indiana — Many counties use Grant Street Group or SRI
›New Jersey — Several counties offer online bidding
›Maryland — Baltimore and other jurisdictions online

If you're investing remotely, online auctions are essential. But remember... the easier it is to participate, the more competition you'll face.

Minimum Investment Amounts

Tax lien certificates can be surprisingly affordable:

›Many liens sell for $100 to $500 (the amount of 1 year's delinquent taxes on a low-value property)
›Average liens in suburban areas: $1,000 to $5,000
›Premium properties: $10,000+

You can realistically start a tax lien portfolio with $1,000 to $2,000 if you target smaller liens in less competitive counties.

Choosing Your State

When deciding where to invest, consider these factors beyond just the interest rate:

›Competition level. Higher rates attract more investors. A 36% rate that gets bid down to 5% isn't really 36%.
›Online access. Can you bid online or do you need to show up in person?
›Redemption period. How long is your capital locked up?
›Subsequent taxes. Do you need to pay future taxes to protect your position?
›Foreclosure process. If a lien doesn't redeem, how expensive and time-consuming is foreclosure?
›Property values. Higher property values mean your lien is more likely to get redeemed (and your collateral is worth more if it doesn't).
