Average claim
Cost to claim
Illinois is holding about $5.0 billion in unclaimed property as of July 2026. You can search your name and claim it for free at icash.illinoistreasurer.gov, the official Illinois State Treasurer (I-Cash) site. A simple claim in your own name takes about 10 minutes and costs nothing.
How to search Illinois’s unclaimed property for free
The only site you need is icash.illinoistreasurer.gov, run by the Illinois State Treasurer (I-Cash). Searching is free, and so is filing your claim. You never pay the state to get your own money, and you never need to hand over money to see what is waiting for you.
Search your last name first, then try maiden names, nicknames, and any business you owned. Illinois lists property under old mailing addresses, so search broadly and check every result that could be you before you file.
The Illinois State Treasurer (I-Cash)
Illinois’s unclaimed property is held by the Illinois State Treasurer (I-Cash). When a bank, employer, or insurer loses touch with you for the state’s dormancy period, it must turn your money over to this office, which then holds it for you to claim.
Illinois runs 'I-Cash' out of the State Treasurer's office and reports to MissingMoney.com. Illinois is notable for its 'enhanced' auto-claim program: the Treasurer proactively mails checks to some residents it can positively identify, without any claim at all — a real letter from the Illinois Treasurer with a check is not a scam.
What’s specific to Illinois
- Branded 'I-Cash.'
- Illinois sometimes mails checks automatically to residents it can verify — a real practice, not a scam.
- Illinois pays interest on some interest-bearing accounts it holds.
How to claim in Illinois
You can do this yourself in about 10 minutes, free. Here is exactly how, step by step.
Search your name on icash.illinoistreasurer.gov
Go to icash.illinoistreasurer.gov, the official Illinois portal, and search your first and last name. Also search maiden names, misspellings, and any business you owned. Searching is free and takes about two minutes.
Open each matching property and add it to your claim
Click any result that looks like you and add it to your claim. Illinois lets you claim several properties at once, so check every address you have lived at.
Confirm your identity
The state asks for your current address and the last four digits of your Social Security number to match you to the property. You never pay a fee and you never send money to claim.
Upload proof and submit
Upload a photo of your government ID and, if asked, proof of your old address. Submit the claim online. Print the confirmation page for your records.
Wait for the state to review and pay
Illinois reviews the claim and pays valid claims by check or direct deposit. Simple cash claims are usually the fastest; claims involving stock or a deceased owner take longer.
Claiming for a deceased relative in Illinois
You can claim property that belonged to a relative who died, but Illinois will ask for more than a simple claim needs. Expect to provide a certified death certificate and proof that you are entitled to the estate — a will, letters testamentary, or a small-estate affidavit, depending on the amount.
Here’s the honest part: heir claims take longer than claims in your own name, sometimes several months, because the state verifies the chain of inheritance. If several heirs exist, each may need to sign. Our guide on claiming unclaimed money from deceased relatives walks through exactly which documents Illinois accepts.

| Utility deposits | 1 year |
| Insurance proceeds | 3 years |
| Stocks and dividends | 3 years |

Illinois finder-fee cap
You do not need a finder. A finder is a company that offers to recover your money for a cut. Their letters are not a scam, but they are unnecessary — the same claim is free if you file it yourself.
Illinois caps what a finder can charge at 10%, under 765 ILCS 1026/15-1305. If a letter asks for more, or asks for money up front, treat it as a red flag.
