A quarterly statement is a document a financial institution sends every three months that summarizes your account activity for that period: the opening balance, every deposit, withdrawal, trade, or fee, and the closing balance. Banks, credit unions, brokerages, and retirement plan administrators all issue them, and the exact contents depend on the account type. These are not just records for your files. Federal rules tie your legal rights (especially your liability for unauthorized transactions) to how quickly you review the statement after it arrives.
Why Institutions Send Them
Quarterly statements exist because regulators require them. For brokerage accounts, FINRA Rule 2231 requires every general securities firm to send an account statement at least once per calendar quarter to any customer whose account had a position, balance, or activity during that period. The statement must show securities positions, money balances, and account activity, with opening and closing balances displayed on the front.1FINRA. FINRA Rule 2231 – Customer Account Statements For deposit accounts, Regulation DD (Truth in Savings) requires banks and credit unions to include specific disclosures on their periodic statements, including interest earned and the annual percentage yield earned during the period.2eCFR. 12 CFR Part 1030.6 – Periodic Statement Disclosures
What’s Inside, by Account Type
The core framework is the same across accounts, but the emphasis shifts depending on what the institution is holding for you.
Brokerage and Investment Statements
A brokerage statement centers on what you own, what it is worth now, and how that value changed. It lists each security in the portfolio (stocks, bonds, mutual funds, exchange-traded funds) with the quantity held, cost basis, and current market price. For fund holdings, you will see the net asset value per share.
The statement separates realized gains and losses, from securities you actually sold, from unrealized gains and losses, which are the paper change in value of securities you still hold. That line matters at tax time because only realized gains trigger a taxable event. Performance figures for the quarter and year-to-date typically appear as well. Brokerage statements also carry a required notice telling 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
Bank Statements
Bank statements for checking and savings accounts document every deposit, withdrawal, electronic transfer, and check that cleared during the quarter. The focus is cash flow rather than investment performance.
Regulation DD requires banks to report the annual percentage yield earned using that exact phrase, 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 If your account was hit with overdraft or returned-item fees, the bank must disclose the aggregate total of those charges. That transparency lets you compare what the account costs against what it earns.
Retirement Account Statements
Statements for 401(k) plans and IRAs are built around contributions and long-term growth. They show your contributions for the quarter, any employer matching contributions, and the total account value broken down by each investment option you have selected.
For employer-sponsored plans, the vesting schedule is a central piece of the statement. Vesting tells you what percentage of your employer’s contributions you actually own if you leave the company. An employee who is 60% vested, for example, would forfeit 40% of employer contributions upon departure. Retirement statements often include projections of future account value based on your current contribution rate and assumed returns.
Sections You’ll Find on Any Quarterly Statement
No matter which type of account you hold, the statement follows a common framework.
Account Summary
The summary sits at the top: balance at the start of the quarter, balance at the end, and the net change. For investment accounts, this section distinguishes between total market value and cost basis. Your investments might be worth $50,000 today but have a cost basis of $42,000, and that gap is your unrealized gain.
Transaction History
A 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 means every check, direct deposit, debit card swipe, and wire transfer. On a brokerage statement, every trade: the security ticker, number of shares, price per share, and whether it was a buy or sell. This is the raw data for reconciliation and tax work.
Fee Disclosure
Every statement itemizes fees charged during the quarter. Bank statements show service charges, ATM fees, and overdraft penalties. Investment statements break out trading commissions, advisory fees, and internal fund expense ratios. A quarterly advisory fee of $375 is $1,500 a year, and over a decade of compounding, fees meaningfully erode returns.
Contact Information and Dispute Instructions
Statements include the institution’s phone numbers, mailing addresses, and online portal details, together with specific instructions for reporting errors. These instructions matter because the deadlines they describe have real teeth.
Why Reading the Statement Promptly Matters
Federal law ties your financial liability for unauthorized transactions directly to how fast you report them after the statement is sent. This is the single biggest reason not to let statements pile up.
Electronic Fund Transfers on Bank Accounts
Regulation E creates a tiered liability structure for unauthorized electronic fund transfers. The longer you wait, the more you can be on the hook for:
- Within 2 business days of learning about a lost or stolen access device, 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 can rise 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 are liable for the full amount of any unauthorized transfers that occur after that 60-day 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. Once you do report, the institution must investigate within 10 business days and report results within 3 business days of finishing. It can take up to 45 days if it provisionally credits your account within 10 business days and gives you access to those funds during the investigation.4eCFR. 12 CFR 1005.11 – Procedures for Resolving Errors
Credit Card Billing Errors
Credit card statements fall under Regulation Z (Truth in Lending). 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 Missing that window does not erase every option, but it does weaken your position considerably.
Paper or Electronic Delivery
Most institutions default to electronic statements, but your right to paper copies is protected by federal law. Under the Electronic Signatures in Global and National Commerce Act (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 requesting paper copies after opting in, and confirm that your hardware and software can access the format. You must consent electronically in a way that demonstrates you can actually open the records.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 charge for paper copies going forward.
Delivery method does not change the deadlines. The clock starts when the statement is transmitted, whether dropped in the mail or posted to your online portal. Electronic delivery often shortens your effective response time, because email notifications are easy to miss or route into spam.
How Long to Keep Quarterly Statements
IRS record retention guidance applies directly, since statements document income, deductions, and cost basis:
- At least 3 years from the date you filed the return, or 2 years from the date you paid the tax, whichever is later, if you file a claim for a credit or refund.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 related to worthless securities or bad debts.7Internal Revenue Service. How Long Should I Keep Records?
- For property and investment cost basis, until the limitations period expires for the year you sell or dispose of the property, because you need the records to calculate gain or loss.7Internal Revenue Service. How Long Should I Keep Records?
That last point is the one most people overlook. If you bought shares of a mutual fund in 2015 and still hold them in 2026, you need the statements showing your original purchase to calculate cost basis when you eventually sell. For long-term investments, this can mean keeping records for decades. Most institutions maintain online archives, but downloading annual backups to your own storage protects you against platform changes or account closures.
Using Quarterly Statements at Tax Time
Quarterly statements are working documents for tax preparation, but they do not replace the official year-end forms you actually file with. The transaction history provides the detail behind capital gains and losses, which brokers formally report to you and the IRS on Form 1099-B.8Internal Revenue Service. About Form 1099-B, Proceeds from Broker and Barter Exchange Transactions Interest income appears on Form 1099-INT, and dividend income on Form 1099-DIV.9Internal Revenue Service. About Form 1099-DIV, Dividends and Distributions
Timing matters. Forms 1099-DIV and 1099-INT must be sent to you by January 31 of the following year, but Form 1099-B, and the consolidated statements that bundle multiple 1099 types together, have a later deadline of February 17, 2026 for tax year 2025.10Internal Revenue Service. General Instructions for Certain Information Returns Your quarterly statements can help you estimate figures ahead of time, but wait for the actual 1099s before filing. Brokerages sometimes issue corrected versions that change the numbers.
