What Is a Tax Lien State?
A tax lien state is a state that allows counties to sell unpaid property tax debt to investors at public auction. When a homeowner stops paying their property taxes, the county needs that money. So instead of waiting, they sell the debt to you.
You pay the overdue taxes. The county gets its money. The homeowner now owes you, with interest.
That interest is set by state law and can range from 8% to 36% annually, backed by real property.
There are roughly 30 tax lien states in the U.S. Let’s look at the best ones.
How Tax Lien Investing Works (Step by Step)
- A homeowner falls behind on property taxes
- The county files a lien on the property
- The county auctions the lien certificate to investors
- You buy the lien, paying the overdue taxes on the homeowner’s behalf
- The homeowner repays you with interest during the redemption period
- If they don’t pay? You can foreclose and potentially own the property
That’s it. Simple, legal, and government-secured.

The 3 Best Tax Lien States Right Now
🏆 Illinois, Up to 36%
Illinois has the highest statutory interest rate of any tax lien state in the country, 18% every six months, which compounds to 36% annually. Downstate counties often see less competition, meaning you can frequently buy at the full rate. The redemption period runs 2–3 years, giving you time to earn interest. Note: foreclosure can be complex and may require legal help.
🥈 Indiana, 10–25%
Indiana offers a short 1-year redemption period, which means faster capital turnover. A $5,000 lien that redeems in 10 months at 25% puts $1,250 in your pocket. Auctions are moving online, making it more accessible. Great for investors who want to reinvest capital quickly.
🥉 Iowa, 24% Annual
Iowa gives you strong returns with minimal institutional competition. Most auctions are still in person, which limits the buyer pool, and that’s actually good for individual investors like you. Less competition means you’re more likely to get the full rate.
Tax Lien vs. Tax Deed: Which Is Right for You?
| Tax Lien | Tax Deed | |
| What you buy | The debt | The property |
| How you earn | Interest payments | Resale or rental income |
| Risk level | Lower | Higher |
| Entry cost | Lower | Higher |
| Best for | Passive investors | Active investors |
In a tax lien state, you buy the certificate and earn interest. In a tax deed state, the county skips the lien and auctions the property directly. Both can be profitable, it just depends on your goals.
How to Start Investing in a Tax Lien State

Start small. Many liens sell for a few hundred dollars. You do not need to be wealthy to get started.
Frequently Asked Questions (FAQ)
Yes. Tax lien auctions are run by county governments and are 100% legal in the states that offer them.
You can begin the foreclosure process after the redemption period ends. In some cases, you could end up owning the property for the cost of back taxes.
Some tax lien certificates sell for under $500. You can start with a small amount and scale as you learn.
The statutory rate is set by law, but in competitive “bid-down” states like Florida or New Jersey, investors compete by accepting a lower rate. To get the full rate, focus on less competitive counties.
No. Tax lien investing does not require a real estate license.
Check your target county’s treasurer or tax collector website. Many auctions are also listed on platforms like Bid4Assets or RealAuction.
Arizona and South Carolina are widely considered the most beginner-friendly. Arizona has clear laws, online auctions, and a 3-year redemption period. South Carolina has a 98%+ redemption rate, meaning you almost always get paid.
