How to Recover Surplus Funds from Tax Foreclosure Sales in South Dakota

Did you know that when a property is sold at foreclosure for more than what was owed, the extra money -- called "surplus funds" -- sometimes belongs to the former owner? Across the country, millions of dollars in surplus funds go unclaimed every year. But in South Dakota, the rules work a little differently than most states.

IMPORTANT UPDATE: South Dakota Law Has Changed

Following the landmark Tyler v. Hennepin County (2023) Supreme Court decision, South Dakota has reformed its tax foreclosure surplus laws. Surplus must now be returned to the prior owner of record, with a 180-day window before funds transfer to the Unclaimed Property Division. This is a dramatic improvement from the prior framework.

Previously, South Dakota generally did not return surplus proceeds from real property tax deed sales to former owners. Under Section 10-25-39, when a property is sold for back taxes, the proceeds are divided among the taxing entities (the county, school district, municipality, etc.) based on their share of the tax levy -- after expenses. The former owner is typically left out.

This makes South Dakota one of the most restrictive states in the country for tax sale surplus recovery.

The Exception: Mobile Homes

There is one important exception. Under Sections 10-22-27 and 10-22-62, surplus funds from the tax sale of a mobile home may be returned to the former owner. If you lost a mobile home to a tax sale in South Dakota, you may have money waiting for you.

Mortgage Foreclosure Surplus

If your property was lost through a mortgage foreclosure (not a tax sale), the news is better. Under Section 21-48-16, surplus proceeds from a mortgage foreclosure must be paid to the Clerk of the Circuit Court. The sheriff is required to notify you and any junior lien holders that surplus funds have been deposited.

To claim mortgage foreclosure surplus:

1. Contact the Clerk of the Circuit Court in the county where the foreclosure happened.
2. Provide proof of your identity and ownership interest.
3. File a written claim for the surplus.

Key Deadlines

Act quickly. Once surplus funds sit unclaimed, they can be transferred to the State as unclaimed property. South Dakota's unclaimed property law (Section 43-41B-36) also imposes restrictions on finder's fee agreements -- agreements made within 24 months of funds being remitted to the State are unenforceable, and after that, fees are capped at 25%.

Watch Out for Finder's Fee Companies

Some for-profit companies will charge you up to 25% of your recovered funds to do paperwork you may be able to handle yourself -- or with free help from a company.

What You Can Do Today

1. Check if you lost a mobile home to a tax sale -- you may be owed surplus.
2. Check for mortgage foreclosure surplus -- contact the Clerk of the Circuit Court.
3. Search South Dakota's unclaimed property database to see if funds in your name have been turned over to the State.

Tyler v. Hennepin County: A Landmark for Property Owners

In 2023, the U.S. Supreme Court ruled unanimously in Tyler v. Hennepin County that governments cannot keep surplus proceeds from tax sales beyond what is owed, finding this violates the Takings Clause of the Fifth Amendment. This landmark decision has strengthened property owners' rights to surplus funds nationwide and prompted many states to reform their tax foreclosure laws. As of 2026, laws in this area are evolving rapidly, so always verify current statutes in your state.
