What Is a Statement of Account: Billing Errors and Disputes

A statement of account is a periodic summary of every charge, payment, fee, and interest amount posted to a financial account during a set billing period, along with the resulting balance. Banks, credit card issuers, mortgage servicers, utilities, and vendors send them so you can see exactly where the account stands at the end of each cycle. They are more than bookkeeping. Under a longstanding common-law rule, a statement you receive and do not object to can be treated as evidence that you agreed the balance was correct.

What Appears on a Statement

Layouts vary, but the same core pieces show up on almost every statement. Together they let you trace how the balance moved from the opening figure to the closing one.

Billing cycle dates that define the reporting period.
Opening balance carried forward from the previous cycle.
Itemized charges, each with a date and description.
Credits and payments applied during the period.
Finance charges, with the interest rate used. Federal rules require creditors to itemize finance charges by type, so periodic interest, minimum charges, and other fees each appear on their own line.¹
Closing balance, which sets the minimum payment and carries into the next period.

Deposit account statements look a little different. Instead of a balance owed, they show the annual percentage yield earned, the dollar amount of interest earned, and an itemized list of any fees taken out during the period.²

Credit card issuers must send a statement for every cycle in which you carry a balance or are charged a finance charge, and the statement has to arrive at least 21 days before the payment due date so you have time to review and pay.³¹ If your mortgage includes escrow for taxes and insurance, the servicer must send an annual escrow account statement within 30 days after the end of the escrow computation year, itemizing the monthly payment, the escrow portion, all deposits and disbursements, and the ending balance.⁴⁵

How a Statement Differs From an Invoice or a Payoff Quote

These three documents look similar and confusing them can cost you.

An invoice covers a single transaction: one purchase or one service rendered. A statement of account aggregates every transaction across an entire billing period and shows the running balance. If you receive five invoices in a month, the statement at month’s end ties them together with your payments and any interest.

A payoff quote, sometimes called a payoff statement, is different again. It shows the exact amount required to fully satisfy a loan today or by a specified date. Unlike a monthly statement, which reflects only your current balance and next scheduled payment, a payoff quote factors in interest that will accrue up to the payoff date plus any early-payment or processing fees. The payoff figure is almost always higher than the balance on your latest monthly statement. For home loans, the mortgage servicer must send an accurate payoff balance within seven business days of receiving a written request.⁶

Why Ignoring a Statement Matters: The Account Stated Doctrine

Under a common-law principle called account stated, if a creditor sends you a statement and you do not object within a reasonable time, courts may treat your silence as an implicit agreement that the balance is correct. That lets the creditor use the unchallenged statement itself as evidence in a lawsuit, cutting down the proof needed to obtain a judgment against you.

Once an account stated is established, your grounds for contesting the balance narrow. Courts generally allow challenges only for reasons like fraud or mistake. What counts as a “reasonable time” depends on the circumstances, but the practical rule is simple. Read every statement when it arrives, and raise any objection promptly. A wrong balance you ignored is much harder to fight later.

Disputing a Billing Error

Federal law gives you a specific process to challenge an error on a credit card or other open-end credit statement, but the process only works if you act quickly.

The 60-Day Deadline

You must send written notice of the billing error within 60 days after the creditor mails or delivers the statement containing the mistake. Miss that window and you lose the protections that follow.⁷ The clock starts when the statement is sent, not when you open it.

What the Notice Needs to Say

Send the dispute to the address the creditor designates for billing inquiries, which is usually 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 at issue.
The reasons you believe it is an error.

The notice cannot be written on a payment stub or slip supplied by the creditor. It has to be a separate communication.⁷ Certified mail gives you a verifiable record of when the creditor received it.

What the Creditor Must Do

The creditor must acknowledge your notice in writing within 30 days, unless the issue is fully resolved in that period. It then has two complete billing cycles, and in any event no more than 90 days, to investigate and either correct your account or send a written explanation of why the statement was accurate.⁷

Your Credit While the Dispute Is Open

During the investigation, the creditor cannot report the disputed amount as delinquent to a credit bureau or threaten to damage your credit rating because of the unpaid disputed amount. If the creditor ultimately concludes the charge was correct and you still disagree, it can report the amount, but it also has to note that the amount is disputed and give you the name and address of every party it notified.⁸

Paper vs. Electronic Delivery

Most institutions default to electronic statements, but federal law protects your ability to choose. Under the Electronic Signatures in Global and National Commerce Act, a company cannot switch you from paper to electronic delivery without first getting your consent.⁹

Before you consent, the institution has to give you a clear explanation of:

Your right to continue receiving paper statements.
Whether the consent covers a single transaction or all future statements.
How to withdraw your consent later, and any consequences such as fees or account changes.
The hardware and software you will need to access electronic records.
How to request a paper copy after consenting and any fee for that copy.

You also have to consent electronically in a way that shows you can actually access documents in the format the institution will use.⁹ Duplicate or archived paper statements often carry a fee, typically in the range of $5 to $7 per statement, though amounts vary.

How Long to Keep Statements

The IRS recommends keeping financial records, including account statements, for as long as they might be relevant to your tax return. In most situations that means at least three years from the date you filed the return the records support, because that is the standard period during which the IRS can assess additional tax.¹⁰

Some situations call for longer retention:

Six years if you underreported your income by more than 25% of the gross income shown on the return, or if the underreported amount is attributable to foreign financial assets exceeding $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 failed to file at all, because the IRS can assess tax at any time.

For records tied to property, such as mortgage statements showing escrow and interest payments, keep them until the statute of limitations runs for the tax year in which you sell or otherwise dispose of the property.¹⁰
