What Does POS Adjustment Mean on Your Statement?

A POS adjustment on your bank statement is a correction your bank made to a debit or credit card transaction after the merchant finalized the actual amount, reflecting the difference between the temporary hold placed at the point of sale and what the merchant ultimately charged. These line items are routine with restaurant tips, gas station fill-ups, and hotel stays, but they can also signal an error. If one looks wrong, federal law gives you 60 days from the statement date to dispute it, and the rules differ depending on whether you used a debit card or a credit card.

How to Spot a POS Adjustment on Your Statement

A POS adjustment usually appears as its own line item rather than replacing the original transaction. When the merchant charges less than the original hold, you’ll see a credit returning the difference, often labeled something like “POS ADJUSTMENT CR” or “POS ADJ CREDIT.” When the merchant charges more than the hold, you’ll see a debit pulling additional funds. Some banks skip the separate line and simply let the pending charge settle at a different number than it originally showed.

The correction happens through batch settlement. Each card transaction starts as a temporary authorization that reduces your available balance. At the end of the business day, the merchant sends all finalized amounts to its payment processor in a single batch, and any gap between the hold and the final figure generates the adjustment once the batch settles.

Why POS Adjustments Happen

Most POS adjustments trace back to a handful of ordinary situations where the merchant can’t know the final amount at the moment you swipe or tap.

Restaurants are the most common source. The server authorizes the pre-tip subtotal when you hand over the card, you write in a tip and sign, and the restaurant closes the ticket for the higher amount. Your bank then adjusts the posted charge to match.

Gas stations place a pre-authorization hold before you pump because the final fuel cost is unknown. Visa and Mastercard have allowed holds of up to $175 at automated fuel dispensers even when the actual purchase is far smaller. Once the pump stops and the station submits the real sale amount, the hold is replaced and you may see a credit for the difference. On a debit card, the original hold can temporarily tie up funds you need elsewhere.

Hotels and rental car companies routinely add an estimated incidental amount on top of the base charge, often $50 to $200 per day for a hotel. On a credit card, the unused portion of that hold drops off without a separate refund. On a debit card, the hotel typically charges the full hold as an actual transaction and then issues a refund for the unused portion, which can take several business days to appear.

International purchases can also trigger adjustments when the exchange rate shifts between authorization and settlement. And technical issues such as double-processing, partial cancellations, or point-of-sale glitches can produce adjustments once the merchant or processor catches the mistake.

Pending Holds vs. Posted Charges

A pending hold reduces your available balance immediately but is not a completed charge. The amount can still change, and sometimes the hold drops off entirely. Pending transactions typically remain in that status for one to five business days before settling.

A posted transaction is final. Once the charge posts, the amount is fixed and cannot change without a separate refund or a formal dispute. The POS adjustment is the mechanism that bridges the two stages. If an adjustment looks wrong after the charge has posted, your only paths forward are asking the merchant for a refund or filing a dispute with your bank.

The 60-Day Deadline to Report an Error

Federal law gives you a limited window to report a POS adjustment you believe is wrong, and the clock is tied to the statement, not to when you noticed the problem.

For debit card transactions, you must notify your bank within 60 days after it sends the statement on which the error first appears. If an unauthorized transfer shows up and you report it within two business days of learning about it, your maximum liability is $50. Wait longer than two business days but still report within 60 days, and your liability rises to as much as $500. Miss the 60-day window entirely, and you could be on the hook for the full amount of any unauthorized transfers that occur after the deadline and before you finally notify the bank.¹

For credit card transactions, you also have 60 days, measured from when the creditor transmits the first statement reflecting the error. Your written notice must go to the specific billing inquiry address the card issuer provides, not the general payment address.²

Because both deadlines run from when the statement is sent, reviewing each statement promptly is the single most important step you can take to protect yourself.

Disputing a Debit Card POS Adjustment

Debit card transactions are governed by the Electronic Fund Transfer Act and Regulation E. Before contacting your bank, gather the original transaction date, the merchant name, any transaction identification numbers from your receipt, and the exact dollar difference between the hold and the posted charge.

You can notify your bank in writing or orally within the 60-day window. Most banks offer an error resolution form through their online portal or at a branch. If you report by phone, the bank can require a written confirmation within 10 business days. If you don’t send that confirmation when required, the bank is not obligated to provisionally credit your account during the investigation.³

Once the bank has your notice, it must investigate and report results within 10 business days. It can extend the investigation to 45 days only if it provisionally credits your account within those 10 business days and gives you full access to the funds. For POS debit card transactions specifically, the extended investigation period is 90 days rather than 45. The same 90-day window applies to foreign transactions and to errors on accounts opened within the previous 30 days. New accounts also get a longer initial window of 20 business days instead of 10 before the bank must resolve the error or issue a provisional credit.⁴

After the investigation ends, the bank must report its findings to you within three business days. If it determines an error occurred, it must correct the error within one business day. If it determines no error occurred, it must explain its findings in writing and may reverse any provisional credit, but only after notifying you first.⁴

Disputing a Credit Card POS Adjustment

Credit card disputes follow the Fair Credit Billing Act and Regulation Z. Send a written billing error notice to the card issuer’s designated billing inquiry address within 60 days of the statement showing the error. The notice should include your name, account number, and a description of the error with the date and amount.²

The card issuer must acknowledge your notice in writing within 30 days unless it resolves the dispute within that period. It then has two complete billing cycles, and no more than 90 days, to investigate and either correct the error or explain why it believes the charge is accurate.²

Regulation Z does not require the issuer to provisionally credit your account. Instead, you have the right to withhold payment on the disputed amount and any related finance charges while the investigation is pending. The issuer cannot report the disputed amount as delinquent or take collection action during that period. If you use autopay with the card issuer, it must not deduct the disputed portion as long as your billing error notice arrives at least three business days before the scheduled payment date.²

Business Accounts Are Not Covered

The protections above apply only to personal consumer accounts. Business debit card transactions fall under Uniform Commercial Code Article 4A, which provides far fewer automatic protections and leaves most dispute terms to the agreement between you and your bank.⁵ The mandatory investigation timelines, provisional credit requirements, and liability caps that protect consumers do not apply. Review your business account agreement to see what dispute rights your bank offers.

If the Bank Denies Your Dispute

A denial does not have to be the end. When the bank concludes no error occurred, it must provide a written explanation and make the documents it relied on available for your review. From there, you have a few options.

Request the bank’s evidence. Ask for copies of the documents it used to reach its decision, and compare them against your own receipts and records.
File a complaint with the Consumer Financial Protection Bureau online or by calling (855) 411-2372. The CFPB forwards complaints to the bank, which generally responds within 15 days, though more complex cases can take up to 60 days.⁶
Consider small claims court for smaller dollar amounts. Filing fees vary by jurisdiction, generally running from around $30 to $75 for modest claims, though they can be higher depending on the amount in dispute and local court rules.

Under the Electronic Fund Transfer Act, a financial institution that fails to properly investigate an error or to provisionally credit your account as required may be liable for actual damages, statutory damages up to $1,000 for individual claims, and your attorney’s fees.³
