What Is a Statement of Account: Errors, Disputes, and the 60-Day Rule

A statement of account is a periodic summary of every charge, payment, fee, and credit posted to your account with a bank, lender, or vendor during a set billing period, along with the balance those entries produce. Banks send them for checking and savings. Card issuers send them each cycle. Mortgage servicers send them annually for escrow. They exist so you can see where an account stands, but they also carry legal weight: under a longstanding common-law rule, a statement you never object to can be treated as evidence that you accepted the balance on it.

That makes reading each one, and speaking up quickly when something is wrong, the whole point.

What Appears on the Statement

Formats vary, but the same building blocks show up on almost every credit statement:

The billing cycle start and end dates.
The opening balance carried over from the last cycle.
Each new charge, fee, or debit, dated and described.
Payments you made and any credits or returns.
Finance charges, with the interest rate applied. Federal rules require creditors to itemize finance charges by type, so periodic interest, minimum charges, and other fees each get their own line.¹
The closing balance, which sets your minimum payment and rolls into the next period.

Deposit accounts look different. Instead of a balance owed, a checking or savings statement shows the annual percentage yield earned, the dollar amount of interest earned, and any fees debited during the period, itemized by type.²

How It Differs from an Invoice or a Payoff Quote

These three documents look alike, and confusing them can cost you money.

An invoice bills a single transaction: one purchase, one service. A statement of account gathers every transaction from a billing period, adds payments and interest, and shows the running balance. Five invoices in a month get reconciled on one end-of-month statement.

A payoff quote is a different animal. It tells you the exact amount needed to fully satisfy a loan on a specific date, including interest that will accrue up to that date and any early-payment or processing fees. The payoff figure is almost always higher than the balance printed on your latest monthly statement, so paying the statement balance will not close the loan. For a home loan, the servicer must send an accurate payoff balance within seven business days of receiving a written request.³

Where You’ll See Statements of Account

Bank Accounts

Periodic statements for checking and savings must disclose the annual percentage yield earned, the dollar interest earned, fees itemized by type, and the number of days in the statement period.² If the account earns $10 or more in interest during the year, the institution files a Form 1099-INT with the IRS and sends you a copy for your return.⁴

Credit Cards and Other Open-End Credit

Card issuers must send a statement for every billing cycle in which you carry a balance or are charged a finance charge. It has to show your previous balance, each transaction with its date, all credits, the finance charge broken down by type, the interest rate, and the new balance.⁵ The statement has to reach you at least 21 days before the payment due date.¹

Mortgage Escrow

If your mortgage includes an escrow account for taxes and insurance, the servicer must send an annual escrow statement within 30 days after the end of the escrow computation year. It has to itemize your monthly payment, the portion going into escrow, all money paid in and out, and the remaining balance.⁶ The statement must also explain how a surplus will be handled and how you’re expected to cover any shortage.⁷

Utilities and Business Vendors

Utility companies and vendors in long-term commercial relationships also issue statements of account. They are less heavily regulated at the federal level, but the structure is the same: opening balance, new charges, payments received, and the amount now due. In business-to-business use, these statements are how accounts receivable and payable get reconciled month over month.

Disputing an Error on a Statement

For credit cards and other open-end credit, federal law gives you a specific process to challenge a mistake, but the window is short.

The 60-Day Window

You must send written notice of the billing error within 60 days after the creditor mails or delivers the statement containing the mistake. Miss the window and the protections below no longer apply.⁸ The clock starts when the statement is sent, not when you open it.

What the Notice Has to Say

Send the dispute to the address the creditor designates for billing inquiries, which is often different from the payment address. Include:

Your name and account number.
A statement that you believe the bill contains an error, and the dollar amount involved.
The reasons you believe it’s an error.

The notice cannot be written on a payment stub. It has to be a separate communication.⁸ Certified mail gives you a record of when the creditor received it.

What Happens Next

The creditor must acknowledge your notice in writing within 30 days, unless the issue is resolved inside that period. From there, the creditor has two complete billing cycles, and no more than 90 days, to either correct the account or send a written explanation of why the statement was right.⁸

While the investigation is open, the creditor cannot report the disputed amount as delinquent to any credit bureau or threaten your credit rating over it. If the creditor concludes the charge was correct and you still disagree, the creditor may then report the amount, but must note that it is disputed and give you the name and address of everyone it notified.⁹

Why Ignoring a Statement Is Risky: the Account Stated Doctrine

Under the common-law doctrine of “account stated,” if a creditor sends you a statement and you don’t object within a reasonable time, a court may treat your silence as implicit agreement that the balance is correct. The unchallenged statement itself can then serve as evidence in a lawsuit, cutting down the proof the creditor needs to win a judgment.

Once an account stated is established, courts generally allow you to contest the balance only on narrow grounds such as fraud or mistake. What counts as “reasonable” time depends on the circumstances, but the practical rule is simple: review each statement when it arrives, and raise objections in writing while the 60-day billing-error window is still open. A wrong balance is far harder to fight after the fact.

Paper, Electronic, and Recordkeeping

Most institutions default to electronic statements now, but they cannot switch you from paper to electronic delivery without your consent under the Electronic Signatures in Global and National Commerce Act.¹⁰ Before you agree, they have to explain your right to keep receiving paper, how to withdraw consent later, and the hardware and software you’ll need to open the electronic files. Duplicate paper copies after you go electronic usually cost a fee, often in the $5 to $7 range depending on the institution.

If you can’t find a past statement, most portals archive them under a “Statements” or “Documents” tab. Older statements may only be available by request through customer service, sometimes for a fee.

For tax purposes, the IRS recommends keeping statements for as long as they support items on a return. In most cases that’s at least three years from the date the return was filed, which is the standard period the IRS has to assess additional tax.¹¹ Longer holds apply in specific situations:

Six years if you underreported income by more than 25% of the gross income shown on the return, or if the underreported amount is tied to foreign financial assets over $5,000.
Four years for employment tax records, measured from when the tax is due or paid, whichever is later.
Indefinitely if you filed a fraudulent return or didn’t file at all, because the IRS can assess tax at any time in those cases.

For property records like mortgage statements showing escrow and interest, hold onto them until the statute of limitations runs on the year you sell or dispose of the property.¹¹
