Can You Claim Tax Deductions Without Receipts? What the IRS Allows

Receipts go missing. The question is what happens to a genuine business expense when the paperwork behind it cannot be found.

The answer is more encouraging than most people expect and narrower than they hope. Other evidence can support a claim, estimates are sometimes accepted, and certain categories carry heightened requirements that no amount of reconstruction will satisfy.

This covers what the rules actually require, where a lower threshold applies, what can stand in for a receipt, how far a reconstruction can be taken, and the claims that should never rely on one.

The IRS Receipt Requirement, What the Law Actually Says

The IRS requires taxpayers to maintain adequate records to substantiate deductions. However, the law does not specify that a physical receipt is the only acceptable proof. What matters is that you have credible, contemporaneous documentation that establishes:

• The amount of the expense
• The time and place of the expense
• The business purpose
• The business relationship (for meals and entertainment)

The $75 Receipt Threshold

The IRS does require receipts for any individual expense over $75 that falls into certain categories (lodging always requires a receipt regardless of amount). For expenses under $75, other documentation may suffice. This does not mean you should skip receipts under $75, it means the IRS is slightly more lenient about reconstruction.

The Cohan Rule: Estimates in a Pinch

Named after George M. Cohan (the entertainer who successfully argued for estimated deductions in court), the Cohan Rule allows courts to permit estimated deductions when records are lost or destroyed, if the taxpayer can show that expenses were definitely incurred, even if the exact amount is uncertain.

Important caveats:

• The Cohan Rule is a judicial doctrine, the IRS does not apply it proactively in audits; only a tax court would.
• It does NOT apply to listed property (vehicles, computers, entertainment), those have strict substantiation requirements under Section 274.
• Estimates must be reasonable and anchored in evidence (industry norms, comparable expenses).
• The Cohan Rule is a last resort, not a planning strategy.

What Works as Proof Instead of a Receipt

The stronger your alternative documentation, the better your position in an audit. A combination of bank statement + calendar entry + email discussing the meeting is far stronger than any single alternative.

Standard Mileage Rate: No Fuel Receipts Needed

When you use the standard mileage rate for vehicle deductions, you do not need to keep fuel, oil, maintenance, or insurance receipts. The rate is designed to cover those costs. You only need a mileage log documenting business trips.

Reconstructed Records: Can You Build Records After the Fact?

Yes, but reconstruct as early as possible, and document your reconstruction process:

• Pull all bank and credit card statements for the year.
• Export transaction data and categorize each expense.
• Supplement with emails, calendar entries, and photos.
• Write a memo explaining the reconstruction and what records were lost (helpful if audited years later).

Reconstruction is credible if done shortly after records are lost. A reconstruction three years later during an audit is far less persuasive.

High-Risk Deductions Without Receipts

• Cash expenses: hardest to prove, the IRS is naturally skeptical of large cash deductions without any paper trail.
• Meals and entertainment: Section 274 requires specific substantiation (who, where, when, business purpose). The Cohan Rule does not apply.
• Vehicle listed property: requires odometer log, not just estimates.
• Home office (actual expense method): requires precise square footage and actual cost documentation.

Best Practice: The Digital Receipt Habit

• Scan every physical receipt immediately with an app (Expensify, Dext, QuickBooks Mobile), they OCR and categorize automatically.
• Forward digital receipts (Amazon, airline confirmations) to a dedicated business email folder.
• Connect your business credit/debit card to your accounting software, transactions import automatically.
• Review and categorize weekly rather than scrambling at year-end.

Pro Tip: The IRS accepts scanned receipts and digital records as valid substantiation. There is no requirement to keep paper originals once you have a legible digital copy.
