A certificate of deposit moves through three stages that quietly decide how much of your money you keep: maturity, dormancy, and escheatment. At maturity, you get a short window to act before the bank renews the CD on its own terms. If you lose track of the account for several years after that, your state’s unclaimed property law classifies it as dormant and the bank eventually hands the balance to the state treasury. Once that happens, your money generally stops earning interest. Understanding each phase, and the moments when a small action protects you, is the difference between a CD that keeps working for you and one that slowly drains value you already earned.
Maturity and the Grace Period
The maturity date is the day your CD’s term ends. On that day, you can withdraw the full principal plus all accrued interest with no penalty. Most banks then give you a grace period of roughly seven to ten days to decide what to do: cash out, move the money elsewhere, or choose a different CD term.
Do nothing during that window and the bank almost always renews the CD automatically for the same term length at whatever rate it currently offers. That rate may be higher or lower than your original one, and you have no input once the grace period closes. The renewed CD is a new contract with its own maturity date, and taking the money out before that new term ends triggers an early withdrawal penalty. Regulation DD requires the bank to disclose the penalty structure when you open the account.1eCFR. 12 CFR 1030.4 – Account Disclosures
Notices the Bank Must Send Before Maturity
You aren’t entirely on your own to track the date. For any auto-renewing CD with a term longer than one month, the bank must mail or deliver a maturity notice at least 30 calendar days before the existing term ends. If the bank offers a grace period of at least five days, it may instead send the notice at least 20 days before the grace period expires.2eCFR. 12 CFR 1030.5 – Subsequent Disclosures
For CDs with terms longer than one year that do not renew automatically, the bank must send notice at least 10 calendar days before maturity, stating the maturity date and whether interest will be paid after that date.2eCFR. 12 CFR 1030.5 – Subsequent Disclosures All of this assumes the bank has your current address. If a notice goes to an old address and you never see it, the dates still run.
When a CD Becomes Dormant
A CD becomes dormant when you have no contact with the bank for a period set by your state’s unclaimed property law. Most states use somewhere between three and five years, and some go as long as seven or ten. The clock generally starts at the date the CD first matured, not the date you opened it.
This is where auto-renewal creates a trap. People assume that because the bank keeps rolling the CD into new terms, the account is “active.” It isn’t. The renewals themselves don’t count as owner activity. A one-year CD that has auto-renewed three times may already be past the dormancy threshold even though the bank is still faithfully managing the investment.
What does count as activity depends on the state, but the following generally resets the clock:
- Logging into your online or mobile banking account
- Contacting the bank by phone, email, or letter about the CD
- Updating information such as an address or beneficiary
- Making a transaction on the CD or a related account at the same institution
That last item matters more than people realize. In some states, activity on a linked checking or savings account at the same bank keeps the CD from being classified as dormant. If you hold a CD at a bank where you also use a checking account regularly, that routine use may protect the CD. If you opened the CD at an institution where you have no other relationship, nothing resets the clock except direct contact with the bank about the account.
What Escheatment Is and What You Lose
Once an account is classified as dormant, the bank doesn’t immediately send the money to the state. Financial institutions must first try to locate you, sending notices to your last known address warning that the funds will be transferred to the state if you don’t respond.3Investor.gov. Escheatment by Financial Institutions If those attempts fail, the bank reports and remits the funds to the state government. Every state, the District of Columbia, and U.S. territories run unclaimed property programs, with their own rules and reporting timelines.4U.S. Department of Labor. Introduction to Unclaimed Property
The state does not take ownership. It acts as a custodian, holding the funds in trust indefinitely until you or your heirs come forward. There is no deadline to claim.
The costly part is what happens to the earnings. A CD earns interest because of your contract with the bank. Once the funds move to the state, that contract is over, and in most states the money simply sits there earning nothing. A small number of states pay some interest on escheated property, but it is the exception.3Investor.gov. Escheatment by Financial Institutions A $20,000 balance that would have earned 4.5% annually loses roughly $9,000 in interest over a decade sitting in a state treasury. Some states also deduct administrative costs for publishing notices and processing claims. Those deductions are usually small, but combined with years of lost interest the erosion adds up.
Tax on CD Interest You Haven’t Withdrawn
CD interest is taxable in the year it is credited to your account or becomes available to withdraw, even if you leave it in the CD.5Internal Revenue Service. Topic No. 403, Interest Received Your bank sends a Form 1099-INT each year if the interest reaches $10 or more. For multi-year CDs, the bank typically credits interest annually, and you owe tax on that amount each year even though pulling it out would trigger a penalty. If you do pay an early withdrawal penalty, you can deduct it from your gross income.6Internal Revenue Service. Publication 550 (2025), Investment Income and Expenses
One point that trips people up: you must report all taxable interest on your federal return even if you never receive a 1099-INT.5Internal Revenue Service. Topic No. 403, Interest Received A CD that has been auto-renewing and generating interest you forgot about still carries a tax obligation. If the bank eventually escheat the account, it may issue a final 1099-INT for interest credited before the transfer.
Getting Escheated Money Back
Searching for the Account
The fastest way to check multiple states at once is MissingMoney.com, a free search tool managed by the National Association of Unclaimed Property Administrators that covers most state databases.7National Association of Unclaimed Property Administrators. National Association of Unclaimed Property Administrators Search every name variation you have used: maiden name, married name, nicknames, former spellings. If you have moved across state lines, search every state where you have lived.
Not all states participate in MissingMoney.com, so check individual state treasury or comptroller websites directly as well. You generally search by name rather than Social Security number. Having the name of the original bank and your last known address at the time of the account helps narrow the results and will matter later when you prove ownership.
Filing the Claim
Once you find a match, the state’s website walks you through filing. Most states offer an online portal, and mail submission is usually also available. You have to prove two things: that you are who you say you are, and that you are the rightful owner. Identity proof means a government-issued ID and your Social Security number. Ownership proof might be an old account statement, the original CD certificate if you still have it, or documents tying you to the address the bank had on file.
Processing times vary widely. Simple claims may resolve within a few weeks; many states allow themselves 90 to 180 days to review documentation, especially for larger amounts. Expect follow-up requests for additional proof during the review.
If the original owner has died, heirs and estate representatives can still file. You typically need a certified death certificate plus documents establishing your legal right to the property, such as a will, a trust agreement, or letters testamentary from a probate court. If the owner died without a will, most states require additional forms and affidavits. The documentation is heavier and the process is slower, but the right to claim does not disappear.
Don’t Pay a Finder for Your Own Money
If you get a letter from a company offering to “recover” unclaimed property for you in exchange for a percentage of the balance, you can almost certainly do the same thing yourself for free. These finder services search the same public databases available to anyone, then charge fees that commonly range from 10% to 35% of the recovered amount. On a $15,000 escheated CD, that is $1,500 to $5,250 for completing a form you could handle in about 20 minutes.
A growing number of states now require finders to disclose prominently that you can file directly with the state at no cost. Some states cap finder fees or void finder agreements signed within a certain period after the property was reported. If you have already signed with a finder, check your state’s rules; you may be able to cancel. The safer path is to start with MissingMoney.com or your state treasury’s website and handle the claim yourself.
