Account Adjustment Notice: Billing Errors and the 60-Day Dispute

An account adjustment notice is the document your bank or card issuer sends when it changes your balance — a charge reversed, a credit posted, a prior transaction corrected. Treat it as something that may need action, not filing. If the adjustment looks wrong, federal law gives you 60 days from the date the statement was sent to file a written dispute with your credit card issuer, and the same 60-day window to report a bank or debit card error.¹² Miss that window and the strongest consumer protections fall away.

Pull Four Things Off the Notice First

Before you do anything else, extract four pieces of information and keep them together. The reference or case number, which you’ll need for every follow-up contact. The effective date of the adjustment, which starts various clocks. The exact dollar amount, and whether it is a charge or a credit. And the billing inquiry address or department contact.

That last one matters more than it looks. The billing inquiry address is not the same as the payment address printed on your statement, and a written dispute sent to the payment address does not trigger your legal protections. Then compare the amount against your own records: statements, receipts, screenshots, prior correspondence. If the numbers line up and the adjustment is in your favor, verify the math and file the notice. If anything is off, you may be looking at a dispute.

Why You Probably Got the Notice

Most adjustment notices come from one of three situations, and knowing which one you’re in tells you whether to act.

The first is a straightforward billing correction. A merchant posted a charge twice, a payment went to the wrong account, a promotional rate didn’t apply. The institution reverses the entry and the notice documents the reversal. Verify and move on.

The second is the resolution of a fraud investigation. When you report an unauthorized charge, the institution usually issues a temporary credit while it looks into the claim. If fraud is confirmed, that credit becomes permanent. If the claim is denied, the credit is reversed and the charge reappears. This is where people get caught: a temporary credit is not a resolution. The matter is only closed when a final adjustment notice confirms a permanent correction. Read these carefully to see which direction the decision went.

The third is regulatory remediation. A regulator finds that a fee or practice was improper and the institution issues refunds across many accounts. If you receive an unexpected credit with a notice referencing a compliance review or regulatory action, that is almost certainly what you’re looking at. These are rarely worth disputing because they’re already in your favor, though any interest paid with the credit may be taxable (see below).

Does Your Situation Qualify as a Billing Error?

Credit card disputes carry the strongest federal protections when they involve what the Fair Credit Billing Act defines as a “billing error.” That category includes:

Charges you didn’t make, or charges in a different amount than you agreed to.
Goods or services that were never delivered or that you properly refused.
Payments or credits the creditor failed to apply correctly.
Computation or accounting mistakes on your statement.
Statements the creditor failed to send to your current address, provided you gave them that address at least 20 days before the billing cycle closed.
Charges for which you’ve asked for documentation or clarification and haven’t received it.

If your dispute fits one of these, the creditor must follow specific investigation procedures once you send written notice.¹ If it doesn’t, you can still contact the institution and escalate to a regulator, but the statutory procedural rights don’t apply.

How to Dispute a Credit Card Adjustment

A phone call to customer service is not a formal dispute. To get full FCBA protection, send a written notice to the creditor’s billing inquiry address — the one printed on your statement, which is different from where you mail payments.¹

Include your name, account number, the dollar amount you believe is wrong, and your explanation of why. Attach copies of supporting documents — receipts, prior statements, correspondence — and keep the originals. Send the letter by certified mail with return receipt requested so you can prove the date the creditor received it.

The 60-Day Clock

Your written notice must reach the creditor within 60 days after the creditor sent the first statement showing the error.¹ The clock runs from the transmittal date, not the day you opened the envelope or checked the app. If you fall behind on reading statements, the deadline can pass unnoticed. Missing it doesn’t bar you from contacting the creditor, but you lose the specific procedural protections of the FCBA, including the right to withhold payment while the investigation runs.

What You Can Withhold

Once you’ve filed a proper written dispute, you don’t have to pay the disputed portion of the balance, including related minimum payment amounts and finance charges, while the investigation is pending. You do still owe any undisputed charges, and you should keep paying those on time to avoid late fees on the part of the bill you aren’t contesting.¹

What the Creditor Has to Do

After receiving your written dispute, the creditor has 30 days to send written acknowledgment, unless it resolves the matter in full within that same 30 days. The investigation itself must conclude within two complete billing cycles and no later than 90 days from the date it received your notice. During that period, the creditor cannot try to collect the disputed amount.¹

Your credit is protected while the dispute is open. The creditor cannot report the disputed amount as delinquent to any credit bureau or threaten your credit standing over your refusal to pay the contested charge. It is allowed to note that the amount is in dispute.³

If the investigation confirms the error, the creditor must correct the account and refund any finance charges that resulted from the incorrect billing, with a written explanation of the correction.¹ If the creditor concludes the original charge was correct, it must send a written explanation of its reasoning and, on request, copies of the documents it relied on. You then get at least 10 days to pay before the creditor can report you as delinquent or impose late fees. If you still disagree, you can submit a follow-up written notice; the creditor may then report the amount as delinquent, but must simultaneously note the dispute and tell you every entity it reports to.³

If the Creditor Blows the Procedure

A creditor that fails to acknowledge your dispute in 30 days, misses the 90-day investigation deadline, or otherwise violates the FCBA’s procedures forfeits the right to collect the disputed amount and any related finance charges — but that forfeiture is capped at $50 regardless of how large the disputed charge was.¹

The real remedy is a private lawsuit. You can recover actual damages plus twice the finance charge on the disputed amount, with a statutory minimum of $500 and a maximum of $5,000 for open-end credit, along with attorney’s fees and court costs.⁴ That $500 floor makes even small procedural violations worth pursuing.

If the Notice Is From Your Bank or Debit Card

Debit cards and checking accounts fall under a different law, the Electronic Fund Transfer Act, implemented through Regulation E. The process looks similar but the details differ, and the consumer protections are weaker.

You still have 60 days from when the institution sent the statement showing the error to report it. Unlike the credit card process, Regulation E accepts both oral and written notices.⁵ The institution can ask you to confirm an oral report in writing within 10 business days, and failing to do so can limit its investigation obligations.

The bank must investigate within 10 business days of receiving your notice. If it can’t finish in time, it can take up to 45 calendar days, but only if it provisionally credits your account within those first 10 business days and gives you access to the funds. The window stretches to 90 calendar days if the account has been open less than 30 days, the transaction was a point-of-sale debit card purchase, or the transfer was international. Provisional credit is still required within 10 business days for new accounts, or 20 business days for the other two situations.⁶

Unauthorized Transactions: Credit vs. Debit

If the adjustment relates to an unauthorized charge, your exposure depends heavily on which type of card was used.

Credit card liability is capped at $50 total, and most major issuers waive even that as a matter of policy. Once you report the card lost or stolen, you owe nothing on charges after the report.⁷

Debit card liability is tiered by how fast you report:

Report within 2 business days of learning of the loss or theft: liability capped at $50.
Report after 2 business days but within 60 days of statement transmittal: liability can reach $500.
Report after 60 days from statement transmittal: no cap on unauthorized transfers that occur after the 60-day window closes.

That last tier is why debit card fraud is so much more dangerous. If someone drains your checking account and you don’t catch it for two months, the bank has no obligation to reimburse what happened after day 60.² Procrastination here has a direct dollar cost.

If the Bank Denies Your Dispute

You have options beyond accepting the outcome.

The Consumer Financial Protection Bureau accepts complaints against banks, credit card companies, and other financial institutions through its online portal. You describe the problem, attach up to 50 pages of supporting documents, and identify the company. The CFPB forwards the complaint to the institution, which typically responds within 15 days; complex cases can take up to 60 days.⁸ A CFPB complaint isn’t a lawsuit, but these filings are tracked, published in a public database, and can draw regulatory attention. That alone can shift the calculus for a bank that denied a borderline dispute.

For FCBA violations specifically, a private lawsuit remains available, with the $500 statutory minimum, $5,000 ceiling for open-end credit, and attorney’s fees already described.⁴ Small claims court is a practical venue for lower-dollar disputes; filing fees generally run between $15 and $375 depending on the jurisdiction.

Tax Note on Remediation Credits

Most adjustments — reversed billing errors, merchant refunds — don’t create a tax obligation, because they restore money that was already yours. But when a bank pays interest as part of remediation, say on funds that were improperly held, that interest is taxable income. Institutions must report interest payments of $10 or more on Form 1099-INT.⁹ If a large regulatory credit lands in your account with an interest component, expect that form at tax time.
