Lost your receipts?You're not alone—and you may still be able to claim those deductions. The IRS accepts alternative documentation, and in some cases, reasonable estimates can work.
However, claiming deductions without proper records is risky. Some expense categories have strict requirements that can't be bypassed. In this guide, you'll learn exactly what the IRS accepts, when estimates are allowed, and how to protect yourself from audit penalties.
IRS Documentation Requirements
The IRS requires "adequate records" to substantiate business deductions. While receipts are the gold standard, they're not the only acceptable form of documentation. The IRS cares about proving:
- The amount of the expense
- The date the expense was paid or incurred
- The place or description of the expense
- The business purpose of the expense
- For certain expenses: the business relationship to people involved
The Cohan Rule Explained
The Cohan Rule comes from a 1930 tax court case involving Broadway entertainer George M. Cohan. The court ruled that taxpayers can estimate expenses when exact records are unavailable, as long as there's clear evidence the expense occurred and the estimate is reasonable.
Important Limitations
- Does NOT apply to travel expenses
- Does NOT apply to entertainment expenses
- Does NOT apply to gift expenses
- Does NOT apply to listed property (vehicles, computers)
- Estimates must be reasonable and supportable
- You must prove the expense actually occurred
Alternative Documentation the IRS Accepts
Bank and Credit Card Statements
Show the amount, date, and payee. Download statements for the entire tax year from your bank's website. These are your strongest alternative documentation.
Canceled Checks
Show the amount, date, and payee. Many banks provide images of canceled checks in your online account or on your statements.
Written Records and Logs
Contemporaneous written records (made at or near the time of the expense) are highly valued by the IRS. Calendars, diaries, and expense logs count.
Digital Records
Email confirmations, online order histories, digital invoices, and app-based records (like Uber receipts in the app) are all valid documentation.
Pro Tip: Check Your Email
Search your email for keywords like "receipt," "order confirmation," "invoice," and vendor names. Many businesses send digital receipts that you may have overlooked.
Expenses Requiring Strict Documentation
Some expense categories have "strict substantiation" requirements under IRC Section 274. For these expenses, the Cohan Rule does NOT apply—you must have adequate records or lose the deduction entirely.
Expenses That Require Strict Records
Travel Expenses
Must document: amount, date, place, business purpose, and trip details
Entertainment Expenses
Must document: amount, date, place, business purpose, and attendees
Gift Expenses
Must document: cost, date, description, business purpose, and recipient relationship
Vehicle Expenses
Must maintain a contemporaneous mileage log with date, destination, business purpose, and miles

Audit Risk and Consequences
Claiming deductions without proper documentation increases your audit risk. If audited, here's what could happen:
Disallowed Deductions
The IRS can disallow any deduction you can't substantiate, resulting in additional tax owed plus interest.
Accuracy Penalties
A 20% penalty may apply if the IRS determines you were negligent or substantially understated your tax.
Fraud Penalties
If the IRS believes you intentionally claimed false deductions, fraud penalties of 75% plus potential criminal charges can apply.
Frequently Asked Questions
Can I claim business expenses without receipts?
Yes, in some cases. The IRS accepts alternative documentation like bank statements, credit card records, and written logs. The Cohan Rule allows reasonable estimates when records are lost, but this is risky and should be a last resort.
What is the Cohan Rule?
The Cohan Rule is a legal precedent that allows taxpayers to estimate expenses when records are unavailable, as long as there's clear evidence the expense was incurred and the estimate is reasonable. However, it doesn't apply to travel, entertainment, or gift expenses.
How long should I keep receipts for tax purposes?
The IRS recommends keeping receipts and records for at least 3 years from the date you filed your return. If you underreported income by more than 25%, keep records for 6 years.
What expenses require strict documentation?
Travel, entertainment, gifts, and vehicle expenses require strict substantiation including amount, date, place, business purpose, and business relationship. These cannot be estimated under the Cohan Rule.
