A non-demand deposit account is any bank or credit union account where the institution reserves the legal right to require at least seven days’ written notice before you withdraw your money. Savings accounts, certificates of deposit, and money market deposit accounts all fit the definition. In exchange for that limitation on access, you earn interest on your balance.
The Seven-Day Notice Rule
The Federal Reserve’s Regulation D sorts every deposit account into one of three buckets: demand deposits, savings deposits, and time deposits. The last two are the non-demand accounts. The dividing line is whether the bank has reserved the right to require at least seven days’ written notice before honoring a withdrawal. If yes, it’s non-demand. If the account is payable on demand or the notice period is shorter than seven days, it’s a demand deposit.1eCFR. 12 CFR 204.2 – Definitions
In everyday life, you almost never see this rule enforced. Walk into a branch, ask to withdraw from savings, and the money comes out that day. Banks reserve the notice right on paper but routinely waive it, processing savings withdrawals as fast as they process checking withdrawals.
The clause is a safety valve. During a bank run or a liquidity crisis, an institution could invoke the seven-day wait to slow outflows. Outside of extreme stress, using it would create the very panic it exists to prevent, so it sits quietly in the account agreement. Its real job is regulatory: it’s what classifies the account as non-demand and lets the bank treat those funds differently on its books.
How These Accounts Differ From Checking
A checking account is a demand deposit. You can write checks, swipe a debit card, and send transfers with no waiting period and no federal cap on the number of transactions. That convenience is why checking accounts historically pay little or no interest; the bank can’t count on your balance sitting still long enough to lend against.
A non-demand deposit works the other way. Because the bank holds the contractual right to delay your withdrawal by a week, it can put your money to work in longer-term lending with more confidence, and it pays you interest in exchange for that predictability. That is why savings accounts, CDs, and money market deposit accounts consistently pay higher yields than a typical checking account.
You may still read that non-demand accounts carry lower reserve requirements than checking. That was true historically, but the Federal Reserve set reserve requirement ratios to zero percent for all deposit categories effective March 26, 2020.2Federal Reserve. Reserve Requirements The seven-day notice right, not reserve treatment, is what now distinguishes these accounts.
The Main Types
Three account types make up almost everything a retail customer will encounter. Each satisfies the definition by giving the institution the right to demand advance notice.
Savings Accounts
A standard savings account is the plainest form of a non-demand deposit. You deposit money, earn interest, and pull funds out through ATMs, transfers, or the branch. The seven-day notice clause is in the account agreement, but banks generally waive it in practice.1eCFR. 12 CFR 204.2 – Definitions
Some banks still cap the number of monthly withdrawals under their own policies and charge excess withdrawal fees, commonly between $3 and $15 per extra transaction.3Consumer Financial Protection Bureau. Why Am I Being Charged for Transactions in My Savings Account? Read the account agreement rather than assume there are no limits.
Certificates of Deposit
A certificate of deposit locks your money away for a fixed term at a guaranteed rate. Terms range from as short as one month to as long as twenty years, depending on the institution. Because you agree not to touch the principal until maturity, CDs generally pay more than a regular savings account.
Under federal rules, a CD is a “time deposit” and must carry an early withdrawal penalty of at least seven days’ simple interest if you take money out within the first six days after deposit.1eCFR. 12 CFR 204.2 – Definitions That is a federal floor. There is no federal ceiling, and banks set their own penalty schedules above it.4HelpWithMyBank.gov. What Are the Penalties for Withdrawing Money Early From a Certificate of Deposit? A common pattern is roughly three months’ interest for a one-year CD and six months’ interest for a two-year CD, though the specifics vary.
When a CD matures, most banks give you a grace period of roughly seven to ten calendar days to withdraw, add funds, or roll into a new CD. If you do nothing, the bank will typically auto-renew at whatever rate it is currently offering, which may be well below what you originally locked in. Put the maturity date on your calendar.
Money Market Deposit Accounts
A money market deposit account blends savings and checking features. You earn interest at rates that often beat a regular savings account, and you get limited check-writing or debit card access. The seven-day notice clause still applies, and the account may impose its own transaction limits.
One point of confusion worth clearing up: a money market deposit account at a bank is not the same product as a money market mutual fund sold by an investment company. The deposit account is federally insured. The mutual fund is not. They share a name and very little else.
Deposit Insurance Coverage
Every non-demand deposit account at a federally insured institution is protected. At banks, the FDIC covers up to $250,000 per depositor, per bank, for each ownership category. Savings, money market deposit accounts, and CDs all qualify.5Federal Deposit Insurance Corporation. Understanding Deposit Insurance
At credit unions, the National Credit Union Administration provides equivalent $250,000 coverage per member through its Share Insurance Fund.6National Credit Union Administration. Share Insurance Coverage Individual accounts, joint accounts, and retirement accounts each receive separate coverage.
One detail catches CD holders off guard: if you hold multiple CDs at the same bank in the same ownership category, the FDIC adds them together. Five $100,000 CDs at one bank leaves $250,000 of that $500,000 uninsured. Spreading balances across institutions or across ownership categories keeps you inside the limit.
Taxes on the Interest You Earn
Interest on any non-demand deposit account is taxable as ordinary income in the year it becomes available to you, whether or not you withdraw it. Savings, CDs, and money market deposit accounts are all treated the same way.7Internal Revenue Service. Topic No. 403 – Interest Received
If your interest at a single institution reaches $10 or more in a calendar year, the bank sends you a Form 1099-INT reporting the amount to you and the IRS.7Internal Revenue Service. Topic No. 403 – Interest Received You owe tax on the interest even if the form never arrives, so keep your own records. For multi-year CDs, interest is generally taxable each year as it accrues, not just at maturity.
Early withdrawal penalties do carry a small tax benefit. The penalty amount is deductible as an adjustment to income on your federal return, and you can claim it even if the penalty exceeds the interest earned that year.
What the Bank Has to Tell You
Federal law requires banks to give you written disclosures about your account before you open it. Under Regulation DD, which implements the Truth in Savings Act, the institution must disclose the interest rate, the annual percentage yield, any fees, and the rules governing the account in a form you can keep.8Federal Reserve. Truth in Savings – Regulation DD
Two numbers appear on every disclosure and advertisement. The interest rate is the base annual rate the bank pays. The APY reflects compounding and tells you what you’ll actually earn over a year if the money sits untouched. When you compare accounts across banks, focus on the APY, because it accounts for how often interest compounds.
If the bank changes your account terms later, you’re owed notice. For fixed-rate accounts, the institution must give at least 30 calendar days’ advance written notice before it decreases your interest rate.9Federal Reserve. Regulation DD Truth in Savings Variable-rate accounts do not carry the same advance-notice right, which is a reason to check which type of rate your account actually uses before you open it.
