Under GAAP accounting for certificates of deposit, you record the CD at cost on acquisition, place it on the balance sheet based on its original maturity, accrue interest as it is earned rather than when it’s paid, and disclose the holdings in enough detail for a reader to judge liquidity and credit risk. Most non-negotiable bank CDs stay at amortized cost for their entire life. Negotiable or brokered CDs can trigger the debt-security classification rules in ASC 320, which changes the measurement model. The acquisition decision drives everything that follows, so the classification work belongs at purchase date, not year-end.
Where the CD Belongs on the Balance Sheet
The first call is classification, and it turns on the instrument’s original maturity at the date you acquire it.
A CD with an original maturity of three months or less from the purchase date qualifies as a cash equivalent. ASC 230-10-20 defines cash equivalents as short-term, highly liquid investments that are readily convertible to known amounts of cash and carry insignificant risk of value changes from interest rate movements. “Original maturity” means maturity from the instrument’s issue date, not the time remaining when you buy it. A six-month CD purchased with 60 days left does not qualify, because the original maturity exceeds three months.
CDs with original maturities beyond three months are investments. If the CD matures within one year of the balance sheet date (or within the operating cycle, whichever is longer), it sits in short-term investments. Anything maturing beyond that window is a long-term investment. When a CD originally classified as long-term crosses the one-year threshold on a later balance sheet date, reclassify it to short-term.
Record the CD at cost at acquisition, which is the face value of the principal deposit. For a standard non-negotiable bank CD, cost and fair value are effectively identical at inception. The entry is simple: debit the appropriate asset account (Certificate of Deposit, Short-Term Investment, or Cash Equivalents) and credit Cash for the deposit amount.
When ASC 320 Applies
Not every CD gets the same ongoing treatment. Whether a CD is a debt security under ASC 320 (Investments — Debt Securities) depends on its form, and that classification controls measurement, impairment, and disclosure downstream.
A standard non-negotiable CD purchased directly from a bank is generally not a debt security. It represents a time deposit with the issuing institution and lacks the transferability that defines a security. One SEC registrant put it plainly in its policies: “The type of certificates of deposit that the Company invests in are not considered debt securities under Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 320, Investments – Debt Securities.”1SEC. Summary of Significant Accounting Policies These CDs are carried at amortized cost without the HTM/AFS/Trading framework.
Negotiable and brokered CDs are different. A negotiable jumbo CD can be sold on a secondary market before maturity, which gives it the characteristics of a debt security. When a CD meets that definition, you must classify it at acquisition into one of three categories:
- Held-to-maturity, where you have both the positive intent and the ability to hold the CD until it matures. HTM securities are carried at amortized cost. The classification is restrictive and cannot be used if you might sell based on interest rate changes, liquidity needs, or better yields elsewhere. Intent and ability must be reassessed each reporting period.
- Available-for-sale, the default for debt securities that are neither trading nor HTM. AFS securities are carried at fair value, with unrealized gains and losses reported in other comprehensive income rather than net income.
- Trading, for CDs bought and held principally for selling in the near term. Trading securities are measured at fair value with changes flowing through net income. This category is rare for CDs.
If you only hold standard non-negotiable bank CDs, the ASC 320 framework does not apply and the CD stays at amortized cost throughout its life. If you hold negotiable or brokered CDs, the classification at purchase date locks in the measurement model, so document the rationale carefully.
Recognizing Interest Income
Under accrual accounting, interest income is recognized as earned over time, not when the bank pays it. A 12-month CD purchased on July 1 that pays all interest at maturity will generate six months of interest income in the first fiscal year even though no cash arrives until the following July.
At each reporting date, calculate the interest earned since the last accrual. For a $100,000 CD earning 4.5% annually, a quarterly accrual would be $1,125 ($100,000 × 4.5% × 3/12). Debit Interest Receivable and credit Interest Income for that amount. The carrying value of the CD itself does not change; the receivable is a separate asset.
When the bank pays, clear the receivable. Debit Cash for the amount received and credit Interest Receivable to zero out the balance. If several accrual periods have passed since the last cash payment, the receivable will reflect the cumulative accrued amount.
Compounding CDs
Some CDs reinvest earned interest into the principal rather than paying it out. No cash changes hands, so instead of debiting Cash, debit the Certificate of Deposit asset to increase the carrying value. The credit still goes to Interest Income, because the revenue is earned whether you receive cash or additional principal. Over the life of a compounding CD, the carrying value grows with each accrual, and subsequent interest calculations should use the updated principal.
Early Withdrawal and Penalties
Breaking a CD before maturity triggers three tasks: remove the CD asset, remove any accrued interest receivable, and recognize the bank’s penalty as a current-period expense.
Work from the net cash proceeds. The bank calculates principal plus accrued interest, then subtracts its penalty. Suppose a CD has a $50,000 carrying value and $500 of accrued interest receivable, and the bank charges a $200 penalty. Net cash is $50,300. The entry debits Cash for $50,300 and Penalty Expense (or Loss on Early Withdrawal) for $200, then credits Certificate of Deposit for $50,000 and Interest Receivable for $500.
The penalty expense hits the income statement in the period of withdrawal. Classify it consistently, either as a component of interest expense, a separate line item, or within other non-operating losses, and apply that treatment uniformly.
One detail catches people off guard. If the penalty exceeds the accrued interest, the bank effectively claws back part of previously recognized income. Cash received will be less than the CD’s carrying value, and the penalty expense covers the full shortfall. Interest income already recognized in prior periods is not reversed; the penalty is a separate charge.
CDs Pledged as Collateral
Entities sometimes pledge CDs to secure letters of credit, loan agreements, or other obligations. A pledged CD does not leave the balance sheet (you still own it), but presentation and disclosure change.
SEC Regulation S-X requires that assets pledged or subject to a lien be designated on the financial statements, with the collateralized obligation briefly identified.2eCFR. Part 210 Form and Content of and Requirements for Financial Statements Whether the CD must be reclassified as restricted depends on the arrangement. Regulation S-X notes that time deposits and short-term CDs “are not generally included in legally restricted deposits,” so a pledge does not automatically make a CD restricted cash. If the pledge genuinely prevents you from accessing the funds during the restriction period, however, separate presentation as a restricted asset is appropriate, and the footnotes must describe the terms.
Credit Losses Under CECL
The current expected credit loss model under ASC 326 technically applies to financial assets measured at amortized cost, which includes CDs. In practice, the allowance for most CDs is zero or close to it.
For CDs held at FDIC-insured banks, deposit insurance covers $250,000 per depositor, per insured bank, for each ownership category.3FDIC.gov. Your Insured Deposits When the balance falls within FDIC limits, the federal guarantee effectively eliminates credit risk, and expected losses can reasonably be concluded to approximate zero. CDs that exceed the insurance threshold at a single institution carry uninsured exposure, and that residual credit risk should at least be evaluated even if the bank has a strong credit rating.
Negotiable CDs classified as HTM debt securities fall under ASC 326-20’s CECL framework explicitly. AFS debt securities follow the separate impairment model in ASC 326-30, which evaluates whether a decline in fair value below amortized cost is credit-related. For non-negotiable bank CDs outside ASC 320, the amortized-cost CECL model in ASC 326-20 still applies, but the analysis is usually brief given the FDIC backstop.
Footnote Disclosures
Footnotes need to give readers enough to evaluate liquidity, credit risk, and valuation of the CD portfolio. A single aggregated line does not do the job when the holdings are material.
Maturity and Classification Detail
Disclose the aggregate carrying amount of CDs, broken out by classification (cash equivalents, short-term investments, long-term investments) and by maturity band. A maturity schedule helps readers project when cash returns and assess whether the portfolio’s duration matches liquidity needs.
Fair Value
ASC 825 requires disclosure of the fair value of financial instruments. For non-negotiable bank CDs, fair value typically approximates carrying value because there is no secondary market price fluctuation and credit risk is backed by FDIC insurance. When fair value materially differs from carrying value, most likely for longer-duration CDs in a volatile rate environment, disclose both. CDs measured at fair value for disclosure purposes are generally classified as Level 2 in the fair value hierarchy, based on observable inputs for similar instruments, unless a quoted price in an active market puts them in Level 1.4SEC. Fair Value Measurements and Financial Instruments
Concentration of Credit Risk
If a significant portion of the CD portfolio sits with a single bank or small group of banks, that concentration requires explicit disclosure. Readers need to know whether one institution’s failure could impair a material chunk of the holdings. Identify the nature of the concentration and whether balances exceed FDIC insurance limits.5FDIC.gov. Understanding Deposit Insurance
Pledged or Restricted CDs
Any CDs pledged as collateral must be identified in the footnotes, with the approximate amount and the obligation they secure. If any CDs are restricted as to withdrawal, describe the provisions of the restriction.2eCFR. Part 210 Form and Content of and Requirements for Financial Statements
Book-to-Tax Differences
GAAP and the IRS do not always recognize CD interest in the same period, and the gap creates reconciliation work at year-end.
Under GAAP, you accrue interest day by day. For federal tax purposes, interest on a CD is generally reportable when it is “credited or set apart” for the depositor without substantial restriction, essentially when the bank makes it available.6Internal Revenue Service. Instructions for Forms 1099-INT and 1099-OID For a CD that pays interest only at maturity, GAAP will have recognized income ratably across every reporting period, while the 1099-INT may report the entire amount in the maturity year. Cash-basis taxpayers see the biggest timing mismatches; accrual-basis taxpayers less so, though cutoffs around year-end can still differ.
Early withdrawal penalties receive favorable tax treatment. The penalty appears in Box 2 of Form 1099-INT and is deductible as an adjustment to gross income, an above-the-line deduction that does not require itemizing.7Internal Revenue Service. Penalties for Early Withdrawal On the GAAP side, the same penalty hits the income statement as an expense in the withdrawal period. Timing usually aligns, but the income statement line (penalty expense) and the tax return line (adjustment to income) sit in different places, so track them separately during reconciliation.
