Section 274(d) substantiation: adequate records for travel, gifts and listed property
Answer: Most business deductions are governed by the general recordkeeping duty in section 6001, under which a person liable for tax keeps such records as the Secretary prescribes. Section 274(d) imposes a stricter regime on three categories: traveling expenses, including meals and lodging while away from home; expenses for gifts; and listed property as defined in section 280F(d)(4). For those, no deduction or credit is allowed unless the taxpayer substantiates, by adequate records or by sufficient evidence corroborating the taxpayer's own statement, four elements: the amount; the time and place of the travel or the date and description of the gift; the business purpose; and the business relationship to the taxpayer of the person receiving the benefit. The practical consequence is stated plainly in Publication 463, which instructs that amounts a taxpayer approximates or estimates cannot be deducted, and in the regulations, which state that this limitation supersedes the Cohan doctrine and that section 274(d) contemplates that no deduction or credit shall be allowed on the basis of such approximations or unsupported testimony of the taxpayer. Entertainment no longer appears in the subsection's list, having been removed when the deduction itself was repealed for amounts paid after 2017.

Jurisdiction: United States — federal
Tax periods: Tax years beginning after 2017, Pub. 463 for 2025 returns, Code checked 2026-09-15
Assumptions
- The expense is otherwise deductible under the general rules and the only question is proof.
- The taxpayer is a business or an individual claiming a deduction in one of the categories section 274(d) names.
- The records being assessed are the taxpayer's own, or records the taxpayer can obtain from a payment provider or employer.
Exclusions
- State and local recordkeeping and substantiation rules.
- Whether an expense is ordinary and necessary, or the limits and disallowances elsewhere in section 274.
- Per diem and accountable plan mechanics, which substitute their own substantiation regime and are analyzed separately.
- Depreciation computation for listed property, and the business-use percentage tests that govern the method.
1. Decide which recordkeeping regime the item sits in
Section 6001 states the baseline duty: every person liable for any tax imposed by the title shall keep such records, render such statements, make such returns, and comply with such rules and regulations as the Secretary may from time to time prescribe. It adds that where the Secretary judges it necessary, a person may be required to keep such records as the Secretary deems sufficient to show whether that person is liable for tax. That is a broad and flexible obligation.
Section 274(d) is not flexible in the same way. It names three categories and provides that no deduction or credit shall be allowed for them unless the taxpayer substantiates the specified elements. The difference between the two regimes is the difference between a deduction that can survive imperfect proof and one that cannot, so classify the item before assessing the file.
The list in subsection (d) as it now reads covers traveling expenses, including meals and lodging while away from home; expenses for gifts; and listed property within the meaning of section 280F(d)(4). Entertainment was removed from that list by the 2017 legislation that repealed the underlying entertainment deduction, so an older checklist that still tests entertainment elements is testing against superseded text. The closing sentence of subsection (d) also disapplies the whole subsection to any qualified nonpersonal use vehicle as defined in section 274(i), which is worth checking before a fleet vehicle is put through this regime.
2. The four elements, tested item by item
The statute requires substantiation by adequate records or by sufficient evidence corroborating the taxpayer's own statement of, first, the amount of the expense or other item; second, the time and place of the travel or the date and description of the gift; third, the business purpose of the expense or other item; and fourth, the business relationship to the taxpayer of the person receiving the benefit. Each element is proved separately, and a file can satisfy three of the four and still fail.
Publication 463 presents the same structure as a table of elements to prove for each expense category, headed amount, time, place or description, and business purpose with business relationship. For travel it asks for the cost of each separate expense for travel, lodging and meals, with incidental expenses allowed to be totaled in reasonable categories; the dates of departure and return for each trip and the number of days spent on business; and the destination or area of travel by name.
The statute's flush language also authorizes the Secretary to provide by regulations that some or all of these requirements do not apply to an expense that does not exceed a prescribed amount. That is the hook under which the documentary-evidence thresholds discussed below operate, and it is worth noting that the relief runs to the documentation requirement rather than to the substantive elements.
3. What makes records adequate
Publication 463 states that documentary evidence will ordinarily be considered adequate if it shows the amount, date, place, and essential character of the expense. It illustrates with a hotel receipt showing the name and location of the hotel, the dates of the stay, and separate amounts for charges such as lodging, meals and telephone; and with a restaurant receipt showing the name and location of the restaurant, the number of people served, and the date and amount. A canceled check together with a bill from the payee ordinarily establishes cost, but the publication cautions that a canceled check by itself does not prove a business expense without other evidence of business purpose.
Timing is part of adequacy. The publication directs that the elements of an expense or of a business use be recorded at or near the time of the expense or use and supported with sufficient documentary evidence, and observes that a timely kept record has more value than a statement prepared later when there is generally a lack of accurate recall. It accepts a log maintained on a weekly basis that accounts for use during the week as a timely kept record, and accepts an expense account statement given to an employer or client if it is copied from the account book, diary, log, statement of expense or trip sheets.
The threshold is regulatory. Section 1.274-5(c)(2)(iii)(A) requires documentary evidence for any expenditure for lodging while traveling away from home, and for any other expenditure of $75 or more, excepting transportation charges where documentary evidence is not readily available; paragraph (B) of the same subdivision treats documentary evidence as adequate where it includes sufficient information to establish the amount, date, place and essential character of the expenditure. Publication 463 restates the rule from the taxpayer's side, identifying situations where a receipt is not required, including where the expense other than lodging is less than $75, and its sample expense record carries the corresponding instruction to attach receipted bills for all lodging and for any other expense of $75.00 or more. Lodging is therefore the category where a receipt is expected regardless of size.
Two further points reduce unnecessary paperwork. The publication states that information already shown on a receipt need not be duplicated in the account book so long as the records and receipts complement each other in an orderly manner, and that confidential information relating to an element need not be entered in the account book provided it is recorded elsewhere at or near the time of the expense and is available to prove the element. Business purpose generally requires a written statement, although the publication notes the degree of proof varies with the circumstances and no written explanation is needed where the purpose is clear from the surrounding circumstances.
4. When the records are incomplete
Publication 463 addresses incomplete records directly and sets out a two-part substitute: the taxpayer's own written or oral statement containing specific information about the element, together with other supporting evidence sufficient to establish the element. It then draws the line that matters. Where the element is the description of a gift, or the cost, time, place or date of an expense, the supporting evidence must be either direct evidence or documentary evidence, direct evidence meaning written statements or the oral testimony of guests or other witnesses setting forth detailed information about the element. Only where the element is the business relationship of guests or the business purpose of the amount spent may the supporting evidence be circumstantial.
That asymmetry is the whole of the practical rule. Purpose and relationship can be inferred from the nature of the work, and the publication gives the example of delivery work supplying circumstantial evidence of business use of a car, with delivery invoices establishing when the car was used. Amounts and dates cannot be inferred in the same way, which is why the note that approximated or estimated amounts cannot be deducted bites hardest on the amount element.
The regulation is explicit about why approximation is unavailable here. It states that the substantiation limitation supersedes the doctrine found in Cohan v. Commissioner, 39 F.2d 540 (2d Cir. 1930), describes that decision as having held that where the evidence indicated a taxpayer incurred deductible travel or entertainment expenses but the exact amount could not be determined the court should make a close approximation rather than disallow the deduction entirely, and states that section 274(d) contemplates that no deduction or credit shall be allowed on the basis of such approximations or unsupported testimony of the taxpayer. That is the regulation's own characterization of the decision, relied on here as regulatory text rather than as an independent reading of the case.
Two named routes remain. Under sampling, an adequate record kept for parts of a tax year may be used to prove business or investment use for the entire year, provided the taxpayer demonstrates by other evidence that the sampled periods are representative of use throughout the year. Under destroyed records, the publication states that where a receipt cannot be produced for reasons beyond the taxpayer's control, a deduction may be proved by reconstructing records or expenses, and identifies fire, flood and other casualties as such reasons. A separate exceptional-circumstances provision allows other evidence that is the best proof possible where a receipt could not be obtained because of the nature of the situation.
Note what none of these routes is. None of them authorizes a plausible figure chosen after the fact. Reconstruction is evidence-driven work against bank records, calendars, mileage between known locations and third-party confirmations, and the reconstruction itself should be documented as such.
5. A records checklist to put in the file
For each item in a section 274(d) category, record: the category and why the item falls in it; the amount and the document evidencing it; the date, and for travel the departure and return dates and business days; the place or, for a gift, the description; the business purpose in writing unless it is evident from the circumstances; and the business relationship of the recipient or beneficiary. Mark which of the four elements each document proves rather than filing documents by date alone, since that mapping is what an examiner is testing.
For the surrounding general records, the IRS recordkeeping page groups supporting business documents into gross receipts, purchases, expenses and assets, and names examples for each, including cash register tapes, deposit information, receipt books and invoices for receipts; canceled checks or other proof of payment, credit card receipts and statements for purchases and expenses; and purchase and sales invoices, real estate closing statements and canceled checks for assets. It states that supporting documents should identify the payee, the amount paid, proof of payment, the date incurred, and a description of the item purchased or service received, and that requirements applying to hard copy books and records apply equally to electronic records.
On retention, Publication 463 states that records must be kept as long as they may be needed for the administration of any provision of the Code, generally meaning three years from the date the return claiming the deduction is filed, with a return filed early considered filed on the due date. It adds that records of the business use of a car must be kept for each year of the recovery period, which extends well beyond the general three-year expectation for that class of property.
This page is about proving a cost. The live Taxterity page Business repairs vs. capital improvements: the §1.263(a)-3 decision sequence is about classifying one, and the two questions are often confused in the same file. Where an item's proof is contested, ask Taxterity a research question that names the category and the records you actually hold, or have it draft a Federal Tax Memo on the substantiation elements for that category, and then check each conclusion against the current statute, regulation and publication.

Limitations
- This page states a proof standard and a records workflow. It is general research information, not advice, and it does not conclude that any particular expense is substantiated or deductible.
- The $75 documentary-evidence threshold and the displacement of approximation are regulatory and are cited to the current eCFR text. The eCFR is authoritative but unofficial; the annual Code of Federal Regulations or the Federal Register should be consulted where official regulatory text is required.
- Publication 463 addresses travel, gift and car expenses. Listed property other than vehicles, and taxpayers using per diem or accountable plan arrangements, follow additional rules not covered here.
- Substantiation is only one hurdle. An item can satisfy section 274(d) and still be disallowed under another provision of section 274 or under the general deduction rules.
- Statutory text was read on uscode.house.gov in the preliminary edition, whose currency line states that it contains the laws in effect on September 14, 2026. That Act amended section 274 in subsections (l), (n) and (o) only; subsection (d), on which this page relies, was last changed by the 2017 legislation that removed entertainment from its list.
