What Is a Tax Receipt? Requirements, Rules, and Recordkeeping

A tax receipt is any document that proves a transaction on your return actually happened — the payment, donation, or purchase behind a deduction or credit you’re claiming. It isn’t a specific form. A canceled check, a credit card statement, an invoice, a cash register slip, or a written acknowledgment from a charity can each serve as a tax receipt, provided it contains enough detail to substantiate what you reported. Federal law requires every taxpayer to keep records sufficient to verify the income, deductions, and credits on their return, and the IRS can disallow a claim entirely when the supporting documents are missing or inadequate.¹

The ordinary slip you get at a coffee shop or gas station often falls short. “$47.50” printed on a faded strip with no vendor, no date, and no description of what you bought won’t hold up during an examination. The IRS expects documents that tie a specific dollar amount to a specific, qualifying purpose.²

What a Valid Tax Receipt Has to Show

IRS recordkeeping guidance points to a short list of data points that every supporting document should capture:

The date of the transaction, which fixes the tax year the expense belongs to.
The exact amount paid.
The payee — the name, and ideally the address, of the vendor, charity, or person receiving the money.
A description of what was purchased or what service was provided. Vague labels like “supplies” or “miscellaneous” invite trouble.
Proof that money actually changed hands: a canceled check, a credit card statement, or an electronic transfer confirmation.

Those elements come straight from IRS guidance on records for business purchases and expenses.³ Certain categories — charitable donations, business travel, meals, and gifts — carry additional requirements on top of these basics.

When You Actually Need a Receipt

You don’t need a physical receipt for every minor expense. Publication 463 requires receipts for all lodging expenses regardless of amount, and for other business costs a receipt is required only when the expense is $75 or more.⁴ Cab fares, tolls, and small meals on the road fall below that line.

Under $75 doesn’t mean no records. You still need to document the amount, date, place, and business purpose. A quick entry in a spreadsheet or expense-tracking app is enough. The threshold exempts you from keeping the paper slip, not from tracking the expense.

Two exceptions push the threshold aside. Business gifts require receipts at any dollar amount, and employee reimbursements under an accountable plan need documentation regardless of size, or the employer has to treat the payment as taxable wages.

Charitable Donation Receipts

Donations follow their own, stricter rules. For any single cash donation of $250 or more, you cannot claim the deduction without a contemporaneous written acknowledgment from the charity.⁵ “Contemporaneous” means you have to hold the acknowledgment before you file the return, or before the filing deadline including extensions, whichever comes first.⁶

The acknowledgment has to state the amount of cash (or describe the property), say whether the charity provided any goods or services in return, and give a good-faith estimate of the value of those goods or services.⁷ That last piece matters when part of your payment buys something. Pay $500 to attend a charity gala where the dinner is worth $150, and your deductible amount is $350. The receipt needs to spell that out.

For cash donations under $250, a bank record, a receipt from the charity, or a written communication showing the charity’s name, the date, and the amount is enough. Unlike business expenses, charitable contributions get no help from the estimation rule discussed below — no documentation means no deduction, regardless of how credible your account is.⁸

Non-cash gifts add another layer. If your total deduction for non-cash contributions exceeds $500, you must file Form 8283 with your return, listing what you donated, when you acquired it, how you valued it, and who received it.⁹ Property valued above $5,000 generally needs a qualified appraisal. The charity’s acknowledgment describes the property but does not assign it a value.

Travel, Meals, and Gifts: Stricter Rules

Business receipts for travel, meals, and gifts carry a requirement that ordinary receipts don’t: you have to prove the business purpose. Section 274 requires you to substantiate four elements — the amount, the time and place, the business purpose, and the business relationship of each person involved.¹⁰ These are the “strict substantiation” rules, and they don’t tolerate estimates.

A restaurant receipt for a business meal should show the restaurant’s name and location, the date, the amount, and the number of people served.⁴ Note the names of the attendees and the business topic discussed on the receipt itself or in a separate log. Most meal deductions fall apart here: the slip is intact, but there’s no record of who was at the table or why.

Digital Receipts

The IRS accepts electronic records in place of paper originals, but the digital copies have to meet specific standards. Under Revenue Procedure 97-22, an electronic storage system must produce records with a “high degree of legibility and readability,” meaning every letter and number is clearly identifiable.¹¹ A blurry phone photo of a faded receipt won’t clear that bar.

The system also needs indexing so you can retrieve any specific record on request, and reasonable controls to prevent unauthorized changes. During an examination, you must produce the records and provide whatever hardware, software, or assistance the IRS needs to read them. One detail catches people out: if you stop maintaining the software or hardware needed to open your stored files, the IRS treats those records as destroyed. Migrating files to current formats is part of the retention obligation.

How Long to Keep Receipts

The general rule is three years from the date you filed the return, or two years from the date you paid the tax, whichever is later.¹² That window matches the standard statute of limitations for the IRS to examine your return. Longer periods apply in specific situations:

Seven years for a claim involving a loss from worthless securities or a bad debt deduction.
Six years if you underreport your income by more than 25%, since the IRS then has six years to assess additional tax.
No limit if you file a fraudulent return or don’t file at all.
For property, keep records tied to the asset’s basis until the limitations period expires for the year you sell or dispose of it. On real estate held for decades, that means holding purchase documents, improvement receipts, and depreciation records for the entire ownership period plus the applicable limitations period afterward.

If you received property in a nontaxable exchange, your basis carries over from the old property to the new one, so you keep the records for both until well after you dispose of the replacement.

What If You Lose a Receipt

Losing a receipt doesn’t automatically kill the deduction, but it weakens your position. For most business expenses, courts apply the Cohan Rule, which permits estimates when records are gone as long as the taxpayer offers credible evidence that the expense occurred. Courts have said they will “bear heavily” against the taxpayer whose poor recordkeeping created the problem, so any allowed amount tends to be less than what was claimed.⁸

The rule has limits. It does not apply to expenses under strict substantiation — travel, meals, and gifts — where the statute demands specific records, not estimates.¹⁰ It also does not apply to charitable contributions, where Congress explicitly barred deductions without a receipt or similar evidence.

If records are destroyed in a fire, flood, or other disaster, you can request copies of prior returns on Form 4506 or transcripts on Form 4506-T, then rebuild from bank statements, credit card records, and duplicate invoices from vendors.¹³ The goal is a secondary paper trail the IRS can verify without relying on your word alone.

The immediate cost of missing documentation is the deduction itself. The burden of proof for every claimed expense falls on you, and the IRS expects documentary evidence to carry it.¹⁴ When the deduction is reversed, the resulting underpayment can trigger the accuracy-related penalty under Section 6662, which adds 20% on top of the tax owed for underpayments caused by negligence or disregard of rules.¹⁵ Interest runs from the original due date of the return. Reasonable cause can excuse the penalty in cases like disaster loss followed by genuine reconstruction efforts, but forgetting to save receipts is not reasonable cause.
