A quarterly statement is a document a financial institution sends every three months that summarizes what happened in your account during that period: every deposit, withdrawal, trade, fee, and balance change, along with your opening and closing balances. Banks, credit unions, brokerages, and retirement plan administrators all issue them, and the specific contents depend on the type of account you hold.
What the Statement Is For
A quarterly statement creates an official record of your account’s activity across roughly 90 days. It shows where your balance stood at the start of the quarter, documents every transaction in between, and ends on a closing balance. For deposit accounts, that means tracking cash flow. For investment accounts, it means tracking both cash and the changing market value of your holdings.
Institutions don’t send these as a courtesy. Regulation drives both the timing and the contents. FINRA Rule 2231 requires general securities firms to send account statements at least once per calendar quarter to any customer whose account had a position, balance, or activity during the period, and those statements must display opening and closing balances on the front along with securities positions, money balances, and account activity.1FINRA. FINRA Rule 2231 – Customer Account Statements On the banking side, Regulation DD (Truth in Savings) requires depository institutions to disclose interest earned and the annual percentage yield earned during the statement period, using that exact phrase.2eCFR. 12 CFR Part 1030.6 – Periodic Statement Disclosures
What’s Inside
Across account types, quarterly statements follow a common framework built from a handful of standard sections.
Account Summary
The summary sits at the top and gives you the quick picture: opening balance, closing balance, and the net change. For investment accounts, this section also distinguishes between total market value and cost basis. Your investments might be worth $50,000 today against a cost basis of $42,000, and that gap is your unrealized gain.
Transaction History
This is the chronological line-by-line record of every movement of money or securities. Each entry shows the date, a description, and the dollar amount. On a bank statement, that covers every check, direct deposit, debit card swipe, and wire transfer. On a brokerage statement, it covers every trade: the security, number of shares, price per share, and whether it was a buy or sell. This is the raw data you’ll use for reconciliation and tax preparation.
Fees
Every statement must disclose the fees charged during the quarter. Bank statements itemize service charges, ATM fees, and overdraft penalties, and Regulation DD requires banks to disclose the aggregate total of overdraft and returned-item fees when they apply.2eCFR. 12 CFR Part 1030.6 – Periodic Statement Disclosures Investment statements break out trading commissions, advisory fees, and fund expense ratios. A quarterly advisory fee of $375 looks small in isolation; annualized, it’s $1,500.
Contact and Dispute Instructions
Statements include the institution’s phone numbers, mailing addresses, and portal details, along with specific instructions for reporting errors. Brokerage statements must also carry a notice advising you to report any inaccuracy or discrepancy promptly and to confirm oral communications in writing to protect your rights under the Securities Investor Protection Act.1FINRA. FINRA Rule 2231 – Customer Account Statements
How the Contents Change by Account Type
Bank Statements
Checking and savings statements document every deposit, withdrawal, electronic transfer, and check that cleared during the quarter. The focus is cash flow and liquidity. Regulation DD requires banks to report the annual percentage yield earned, the dollar amount of interest earned, and an itemized list of fees charged during the period.2eCFR. 12 CFR Part 1030.6 – Periodic Statement Disclosures
Brokerage Statements
Brokerage statements center on what you own, what it’s worth today, and how that value changed. They list each security in the portfolio (stocks, bonds, mutual funds, exchange-traded funds) with quantity held, cost basis, and current market price. For fund holdings, the statement shows the net asset value per share.
Realized gains and losses (from securities you actually sold) appear separately from unrealized gains and losses (paper changes in value on securities you still hold). That distinction matters at tax time because only realized gains trigger a taxable event. Performance metrics usually appear too, showing returns for the quarter and year-to-date.
Retirement Account Statements
Statements for 401(k) plans and IRAs are built around long-term growth and contribution tracking. They show your contributions for the quarter, any employer matching contributions, and the total account value broken down by each investment option you’ve selected.
For employer-sponsored plans, the vesting schedule is a central piece. Vesting tells you what percentage of your employer’s contributions you actually own if you leave the company. An employee who is 60% vested would forfeit 40% of employer contributions on departure. Retirement statements often include projections of future account value based on your current contribution rate and assumed returns.
Why the Statement Matters When It Arrives
Reading the statement quickly isn’t just good hygiene. Federal law ties your financial liability for unauthorized transactions to how fast you report them after the statement is sent.
For electronic fund transfers from bank accounts, Regulation E creates a tiered structure that escalates the longer you wait:
- Within 2 business days of learning about a lost or stolen access device, your liability is capped at $50 or the amount of unauthorized transfers before you notified the bank, whichever is less.3eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
- After 2 business days but within 60 days of the statement being sent, liability rises to as much as $500.3eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
- Beyond 60 days after the statement is sent, you’re liable for the full amount of unauthorized transfers that occur after that window and before you finally notify the bank.3eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
That third tier is unlimited. The 60-day clock starts when the institution transmits the statement, not when you open it.
When you do report an error, the institution must investigate within 10 business days and report results within 3 business days of completing the investigation. It can take up to 45 days if it needs more time, but only if it provisionally credits your account within 10 business days and gives you full access to those funds during the investigation.4eCFR. 12 CFR 1005.11 – Procedures for Resolving Errors
Credit card statements fall under Regulation Z rather than Regulation E, but the dispute window is similar: you have 60 days from the date the creditor transmitted the statement reflecting the billing error to send a written dispute notice to the address specified on the statement.5CFPB. 12 CFR 1026.13 – Billing Error Resolution
Paper or Electronic
Most institutions now default to electronic statements, but your right to receive paper copies is protected by federal law. Under the E-Sign Act, a financial institution cannot switch you to electronic-only delivery without your affirmative consent.6Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity
Before you consent, the institution must tell you about your right to receive paper records, explain how to withdraw consent later, describe any fees for paper copies after you opt into electronic delivery, and confirm your hardware and software can actually access the electronic format. Consent has to happen electronically in a way that demonstrates you can access records in the format the institution will use.6Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity You can withdraw consent and return to paper at any time, though the institution may then charge for paper copies.
The legal deadlines for reporting unauthorized transactions run from when the statement is transmitted, whether that means dropped in the mail or posted to your online portal.
How Long to Keep Them
Quarterly statements document income, deductions, and cost basis, so IRS retention guidance applies:
- At least 3 years from the date you filed the return, or 2 years from the date you paid the tax if later, as a general rule.7Internal Revenue Service. How Long Should I Keep Records?
- 6 years if you failed to report income exceeding 25% of the gross income shown on your return.7Internal Revenue Service. How Long Should I Keep Records?
- 7 years for records tied to worthless securities or bad debts.7Internal Revenue Service. How Long Should I Keep Records?
- For property and investment cost basis, keep records until the limitations period expires for the year you sell or dispose of the property, because you need them to calculate gain or loss.7Internal Revenue Service. How Long Should I Keep Records?
That last point catches most people out. If you bought shares of a mutual fund in 2015 and still hold them in 2026, the statements showing your original purchase are what you need to calculate cost basis when you sell. For long-term investments, that can mean holding records for decades. Most institutions maintain online archives, but downloading annual backups protects you against platform changes or account closures.
Quarterly statements don’t replace the year-end tax forms you actually file with. Interest income arrives on Form 1099-INT, dividend income on Form 1099-DIV,8Internal Revenue Service.
