A sales slip is the paper or electronic record a merchant gives you after a purchase, listing what you bought, what you paid, and how you paid. It confirms the transaction, but its real value shows up later: when a charge on your statement looks wrong, when a card is used without your permission, when a warranty claim needs proof of purchase, or when the IRS asks you to back up a deduction. Federal law shapes what the slip must show, what it must hide, and how long it matters.
What’s Printed on a Sales Slip
Most sales slips carry the same core details: the merchant’s name and location, the date, a description of each item or service, individual prices, a subtotal, any sales tax, the total, and the payment method. For card transactions completed at an electronic terminal, federal regulations require the receipt to show the transaction amount, the date, the type of transfer, an account identifier limited to four digits or letters, and the terminal’s location.1Consumer Financial Protection Bureau. 12 CFR 1005.9 – Receipts at Electronic Terminals; Periodic Statements
Beyond those federal basics, individual states set their own rules on how sales tax must appear. Some require a separate line showing the exact tax; others let the tax be folded into the displayed price if certain disclosures are made.
What Federal Law Keeps Off the Receipt
Your full card number and expiration date should never appear on a printed receipt. Under the Fair and Accurate Credit Transactions Act, merchants may print no more than the last five digits of a credit or debit card number on an electronically printed receipt, and the expiration date cannot appear at all.2Office of the Law Revision Counsel. 15 USC 1681c – Requirements Relating to Information Contained in Consumer Reports The rule covers electronically printed slips only; the old carbon-copy imprints and handwritten slips are exempt, though those have mostly disappeared.
If a merchant’s system prints your full number or expiration date, you don’t have to prove anyone stole your identity to have a claim. For a willful violation, the statute allows damages of $100 to $1,000 per receipt, plus potential punitive damages and attorney’s fees.3Office of the Law Revision Counsel. 15 USC 1681n – Civil Liability for Willful Noncompliance
Using a Sales Slip to Dispute a Credit Card Charge
When a charge looks wrong on a credit card statement, the sales slip is your evidence. The Fair Credit Billing Act gives you 60 days from the date the creditor sent the statement to file a written dispute for billing errors, including charges for the wrong amount, charges for items never delivered, and computational mistakes.4Office of the Law Revision Counsel. 15 USC 1666 – Correction of Billing Errors The original slip lets the bank compare what you authorized against what was processed.
Once the creditor receives your written notice, it must acknowledge the dispute within 30 days and resolve the investigation within two complete billing cycles, with an outer limit of 90 days.5Consumer Financial Protection Bureau. 12 CFR 1026.13 – Billing Error Resolution During that window, the creditor cannot try to collect the disputed amount or report it as delinquent.
Debit Card Disputes Are More Urgent
Debit card transactions follow Regulation E, not the Fair Credit Billing Act, and the consequences of waiting are steeper. If your card is lost or stolen, reporting it within two business days caps your liability at $50. Wait longer than two days but report within 60 days of receiving your statement, and your exposure rises to as much as $500. Miss the 60-day window, and there is no cap on what you can lose from unauthorized transfers that happen after the deadline.6Consumer Financial Protection Bureau. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
The same 60-day clock governs any error on a periodic statement. Notify your financial institution within 60 days after it sends the statement reflecting the error, or the institution has no obligation to investigate.7Consumer Financial Protection Bureau. 12 CFR 1005.11 – Procedures for Resolving Errors Keeping sales slips and matching them against your statement each month is the simplest way to catch problems before the window closes.
How Long to Keep Sales Slips
The IRS requires you to keep records that support income, deductions, or credits for as long as those records could matter, generally until the applicable statute of limitations expires.8Internal Revenue Service. Topic No. 305, Recordkeeping Three timeframes cover most situations:
- Three years is the standard period for most returns, measured from the filing date.
- Six years applies if you failed to report income exceeding 25% of the gross income shown on your return, or if undisclosed income is attributable to foreign financial assets totaling more than $5,000.
- Seven years applies if you filed a claim for a loss from worthless securities or a bad debt deduction.
These timeframes apply to individuals and businesses alike.9Internal Revenue Service. How Long Should I Keep Records? If the IRS reviews your finances and you can’t produce supporting records, the agency can disallow the deductions you claimed.
Business travel is handled a little differently. For travel, meals, and car expenses, the IRS does not require a physical receipt for any individual expense under $75, with one exception: lodging always requires a receipt regardless of the amount.10Internal Revenue Service. Publication 463, Travel, Gift, and Car Expenses The threshold comes from Treasury Regulation § 1.274-5, which also waives the receipt requirement for transportation charges where a receipt is not readily available.11GovInfo. 26 CFR 1.274-5 – Substantiation Requirements The $75 rule doesn’t mean you can forget about the expense; you still need a record of the amount, date, place, and business purpose, usually a credit card statement paired with a written log.
If you lose a receipt for a larger expense, you aren’t automatically sunk. The IRS allows taxpayers to meet their burden through adequate records or sufficient evidence supporting their own statement.12Internal Revenue Service. Burden of Proof Bank statements, card records, and contemporaneous written notes can serve as secondary evidence, but reconstructing an expense after the fact is always harder than keeping the slip.
Thermal Receipts Fade
Most printed receipts use thermal paper, which doesn’t carry real ink. The image is a heat-sensitive chemical coating that degrades under light, heat, humidity, and friction. A thermal receipt stored in a wallet or glove compartment can become unreadable within six months to two years. Sunlight and temperatures above about 77°F speed the process considerably.
That creates an obvious problem when you need a receipt three or more years later for a tax audit. Scan or photograph receipts at 300 DPI or higher and save them as PDFs soon after purchase. Cloud storage protects against hard-drive failure. The IRS accepts digital copies as long as they are accurate and legible, so the paper original is not strictly necessary once you have a good scan. If a receipt has already started to fade, photograph it right away and adjust the contrast digitally to recover what you can. You can also ask the vendor for a duplicate invoice, though most retailers only keep transaction records for a limited period.
Agreeing to a Digital Receipt Instead of Paper
Retailers increasingly ask whether you’d rather receive a receipt by email or text. Under the Electronic Signatures in Global and National Commerce Act, a business cannot simply replace your paper receipt with an electronic version. You have to give affirmative consent first, and before you consent, the business must clearly disclose your right to receive a paper copy, the process for withdrawing consent, whether consent covers just this transaction or all future ones, and the hardware and software you’ll need to open the record.13Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity
Your consent itself has to happen electronically in a way that proves you can actually access the format the business plans to use. If the business later changes its system in a way that could stop you from opening your receipts, it must notify you of the new requirements and get your consent again. You can withdraw consent at any time.
Throwing Receipts Away
Even a truncated card number paired with your name, the merchant, and the date can help someone committing fraud. The FTC’s Disposal Rule requires anyone holding consumer information for a business purpose to take reasonable steps to prevent unauthorized access during disposal, including shredding, burning, or pulverizing paper so the information cannot be reconstructed.14eCFR. 16 CFR Part 682 – Disposal of Consumer Report Information For personal use, a cross-cut shredder handles paper receipts well, and permanently deleting old digital receipts from cloud storage and local backups reduces your exposure if an account is ever compromised.
