If your property was sold at a tax deed sale in Idaho, surplus funds may be available. Idaho follows a tax deed process, meaning that when property taxes remain unpaid, the county eventually takes ownership of the property through a tax deed and sells it at public auction. If the sale price exceeds the total amount of delinquent taxes, penalties, interest, and costs, the excess is classified as surplus funds. The Idaho statutes that address tax deed sales and excess proceeds are referenced below — read the current statute text on the official Idaho Legislature website. The practical reality is that the process requires former owners to take action; counties do not actively chase you down.
One of the most significant developments in Idaho surplus funds law came with Senate Bill 1347a, which amended Idaho Code 31-808. This legislation established that unclaimed surplus funds from tax deed sales are transferred to the Idaho State Treasurer rather than remaining indefinitely with county treasurers. The state maintains a searchable unclaimed property database at yourmoney.idaho.gov, where former property owners can look up funds that may have been transferred on their behalf. If surplus funds from your property sale have already been sent to the state, your claim must be filed through the State Treasurer's office instead of the county.
How Idaho Tax Deed Sales Generate Surplus Funds
When an Idaho property owner falls behind on property taxes, the county records a tax lien against the property. If the delinquency continues, the county treasurer can obtain a tax deed, transferring ownership to the county. The county then sells the property at a public auction. When the winning bid exceeds the total tax debt and associated costs, the remaining balance becomes surplus. Idaho counties are required to hold these excess proceeds for the former owner, but they are not obligated to conduct extensive searches to locate you. The responsibility to discover and file a claim rests with the former property owner.
Key Idaho Counties With Surplus Fund Activity
Ada County is by far the largest source of surplus funds in Idaho. As the home of Boise, the state capital and most populous city, Ada County processes a high volume of tax deed sales each year. Ada County is also one of the more accessible counties for claimants because it publishes surplus fund claim forms directly on its website. You can contact the Ada County Treasurer's office to request documentation and begin the claims process.
Canyon County borders Ada County and includes the cities of Nampa and Caldwell. As the second most populous county in Idaho, Canyon County regularly conducts tax deed auctions that generate surplus funds. The Canyon County Treasurer handles all excess proceeds claims and can provide information about specific properties that produced overages at sale.
Kootenai County is located in northern Idaho and includes Coeur d'Alene, one of the fastest-growing areas in the state. Rising property values in the Kootenai County area have made it increasingly common for tax deed sales to produce significant surplus amounts, as auction prices often far exceed the relatively small tax debts that triggered the sale. Former owners in this region should check with both the county treasurer and the state unclaimed property portal.
How to Claim Surplus Funds in Idaho
To begin a claim, contact the county treasurer's office in the county where your property was located. You will typically need government-issued identification, proof that you were the owner of record at the time of the tax deed sale, and the property address or parcel number. If the county has already transferred unclaimed surplus to the Idaho State Treasurer (Idaho Code 31-808 is the relevant statute), the claim path shifts to the state through yourmoney.idaho.gov. Some counties, like Ada County, provide downloadable claim forms on their websites, while others require you to submit a written request. If multiple parties held an interest in the property, such as a mortgage lender or lien holder, the county or state may need to determine priority before releasing the funds.

Check Both the County and the State
Idaho's transfer of unclaimed surplus to the State Treasurer means you should search in two places. Start with the county treasurer where the property was sold, then check the Idaho State Treasurer's unclaimed property database. Many former owners miss out on funds simply because they only check one source. Acting quickly is important because the longer surplus funds sit unclaimed, the harder they can be to track down as records age and offices change procedures.
Begin your search by browsing our Idaho surplus funds directory to see available records organized by county. You can also contact your county treasurer directly or visit yourmoney.idaho.gov to check whether your surplus has been transferred to the state. The sooner you file your claim, the better your chances of recovering the money you are owed.
