What Happens If You Get Audited and Don’t Have Receipts?

Getting audited by the Internal Revenue Service can be stressful for any taxpayer. An audit means the IRS wants to verify the information reported on your tax return — including your income, deductions, and credits.

One of the most common concerns during an audit is documentation. The IRS typically asks for receipts or other records that prove your expenses were legitimate.

But what happens if you’re audited and don’t have those receipts anymore?

Receipts can be lost, thrown away, or never collected in the first place. While this can complicate an audit, it doesn’t automatically mean you’ll lose every deduction you claimed.

In many cases, the IRS may accept alternatives to receipts for IRS audits such as other documentation, reconstructed records, or reasonable estimates supported by evidence.

In this guide, we’ll explain:

• What the IRS actually requires for receipts
• What happens during an audit if receipts are missing
• The legal protection known as the Cohan Rule
• The penalties you could face if records cannot be verified
• How to reconstruct records if receipts are lost
• Best practices to avoid this problem in the future

Being audited by the IRS means the agency is reviewing your tax return to verify the accuracy of reported income, deductions, and credits.

An audit does not automatically imply wrongdoing. It is simply a process where the IRS requests supporting documentation to confirm that your return is accurate.

During an audit, the IRS may:

• Review receipts, bank statements, invoices, or digital records
• Ask for logs or calendars for business expenses
• Verify income reported from employers, clients, or financial institutions

Most audits are routine and can be resolved by providing adequate documentation. However, failing to respond or lacking proof for claimed deductions may lead to adjustments, additional taxes, or penalties.

Being prepared and organized can make the audit process faster and less stressful, and for self-employed taxpayers, thorough records are especially important to support Schedule C deductions.

Receipts serve as proof that a transaction occurred and that an expense was legitimate. The IRS requires taxpayers to maintain adequate records to support any deductions or credits claimed on a tax return.

According to IRS Publication 583, taxpayers should maintain documentation showing:

• The amount of the expense
• The date of the transaction
• The place or vendor where the purchase occurred
• The business purpose of the expense

Receipts are especially important for deductions such as:

• Business travel
• Meals and entertainment
• Vehicle expenses
• Charitable donations
• Office supplies or equipment

Without documentation, the IRS may disallow deductions, which can increase your tax bill.

The IRS does not require a receipt for every single expense, but there are important thresholds and documentation rules.

For most travel and business expenses, the IRS requires receipts for expenses over $75.

This guideline comes from Revenue Procedure 2019-46, which outlines substantiation requirements for business expenses.

However, there are exceptions.

Receipts are required regardless of amount for:

• Lodging expenses
• Certain travel expenses where detailed documentation is required

For charitable contributions:

• Donations over $250 require written acknowledgment from the charity.
• Smaller donations may be supported by bank or credit card records.

The IRS accepts digital or electronic records as long as they accurately reflect the original information. Guidance on electronic records is provided in Revenue Procedure 98-25.

That means documentation such as:

• emailed receipts
• PDF invoices
• digital accounting records

can be used during an audit.

Self-employed taxpayers who file Schedule C face higher audit rates due to the variety of deductible expenses claimed.

Common triggers for a Schedule C audit include:

• High deductions relative to reported income
• Home office claims
• Vehicle and mileage deductions
• Meals, entertainment, or travel expenses

If receipts are missing:

• The IRS may request bank statements, invoices, or logs
• Reasonable estimates may be allowed under the Cohan Rule
• Reconstructing records demonstrates good-faith compliance, reducing penalties

For business expenses, you should maintain:

• Receipts or invoices for purchases
• Mileage logs and calendars for travel
• Bank or credit card statements supporting payments
• Digital records such as email confirmations or accounting software entries

Even small or recurring expenses should be documented to avoid disallowed deductions during an audit.

Losing receipts doesn’t automatically disqualify your deductions. Steps to take include:

1. Contact vendors or suppliers for duplicate receipts or invoices
2. Download bank and credit card statements showing the expense
3. Check email for digital receipts or purchase confirmations
4. Reconstruct logs for mileage, meals, or other recurring expenses
5. Check calendars for meetings or client visits supporting the expense
6. Request missing W-2s/1099s from the IRS if needed

Providing multiple forms of evidence increases your chances of the IRS accepting your deduction.

Most taxpayers are never audited, but certain factors increase the likelihood of IRS scrutiny.

Common audit triggers include:

• High deductions relative to income
• Large or unusual business expenses
• Self-employment income
• Cash-heavy businesses
• Discrepancies between tax forms (such as W-2s or 1099s)

The IRS also uses automated scoring systems to identify tax returns that appear statistically unusual.

Even if nothing is wrong with your return, it may still be selected for review.

Not all audits are the same. The type of audit determines how extensive the review will be and what documentation you may need to provide.

This is the most common type of audit. It is conducted entirely by mail. The IRS typically requests specific documents related to certain deductions or income items.

You may be asked to submit:

• receipts
• bank statements
• copies of tax forms

These audits are usually limited in scope and easier to resolve.

An office audit requires you to meet with an IRS examiner at a local IRS office.

The auditor may request additional documentation such as:

• expense logs
• mileage records
• invoices
• financial statements

A field audit is the most detailed type of audit.

An IRS agent visits your home, business, or accountant’s office to review records in person. These audits often involve businesses or higher-income taxpayers.

If you’re audited without receipts, the IRS will first ask whether other documentation exists. The auditor’s goal is to determine whether the expenses you claimed were legitimate.

Possible outcomes include:

If you can provide other records showing that the expense occurred, the IRS may allow the deduction.

If evidence exists but the amount cannot be confirmed, the IRS may allow only part of the deduction.

If the IRS finds insufficient evidence, it may disallow the deduction entirely, which increases your tax liability.

This is where an important legal principle may help taxpayers.

A key legal precedent that sometimes helps taxpayers during audits is the Cohan Rule.

The rule originates from the landmark tax case Cohan v. Commissioner, involving entertainer George M. Cohan.

Cohan claimed significant travel and entertainment expenses but lacked detailed receipts. The court acknowledged that the expenses likely occurred and allowed reasonable estimates based on available evidence.

The rule may apply when:

• A taxpayer can show the expense likely occurred
• Documentation was lost or destroyed
• There is supporting evidence, such as bank statements or logs

The Cohan Rule does not apply to all deductions.

Certain expenses still require strict documentation, including:

• Travel
• Meals
• Vehicle expenses
• Gifts

Because of these restrictions, the rule is usually considered a last-resort option when records are unavailable.

Some deductions can still be claimed if other evidence supports them:

• Small cash expenses: Business purchases under $75
• Charitable donations: Up to $250 with bank or credit card records
• Mileage: Documented in a log or calendar
• Estimated expenses under the Cohan Rule: Reasonable business expenses supported by evidence
• Digital records: Email confirmations or PDF invoices

Tip: Combining multiple forms of proof strengthens your claim and reduces audit risk.

If receipts are missing, the IRS may accept other types of documentation that reasonably prove an expense occurred.

Common alternatives include:

• Bank statements
• Credit card statements
• Canceled checks
• Vendor invoices
• Email confirmations
• Accounting software records
• Written expense logs
• Business calendars showing meetings or travel
• Third-party verification from vendors

When the IRS asks for documents, providing multiple forms of documentation often strengthens your case during an audit.

If you no longer have receipts, you may still be able to rebuild your records. Here are practical steps many tax professionals recommend.

Many businesses can provide copies of receipts or invoices for past purchases.

Statements can confirm:

• transaction date
• merchant name
• purchase amount

Online purchases and travel bookings often include email confirmations that can be used as documentation.

Business calendars can help establish the purpose of meetings, travel, or meals connected to expenses.

You can estimate travel distances by reviewing addresses and mapping routes between locations.

If forms like W-2 or 1099 are missing, copies can often be obtained from the IRS or the issuing organization.

Reconstructing records demonstrates good-faith compliance, which may reduce penalties.

If deductions cannot be verified, the IRS may assess additional taxes and penalties.

As of 2025, common penalties include:

The IRS may impose a 20% penalty on the amount of underpaid tax due to negligence or improper documentation.

If the IRS determines that a taxpayer intentionally misrepresented information, the penalty can reach 75% of the underpaid tax.

Interest accrues on unpaid taxes until they are paid. The IRS interest rate is 8% annually as of Q1 2025.

These charges can add up quickly, which is why documentation is so important during an audit.

The IRS generally has a three-year statute of limitations to audit a tax return.

However, there are important exceptions:

• Six years if income is underreported by more than 25%
• Unlimited time if fraud is suspected

Because of these timelines, taxpayers are typically advised to keep records for at least three to seven years.

Most audits follow a predictable sequence.

1. Audit notice arrives: The IRS sends a letter identifying items under review.
2. Documentation request: The IRS asks for records supporting deductions.
3. Review process: The auditor examines submitted documents.
4. Proposed changes: The IRS may adjust the tax return.
5. Response or appeal: Taxpayers can accept the changes or challenge them.

Simple correspondence audits may be resolved within three to six months, while more complex audits can take longer. If you wish, you can engage a fractional CFO for the time being to provide you with audit support. On the other hand, in case there’s an audit dispute, the IRS offers free assistance to small businesses.

Modern recordkeeping tools make it easier to avoid missing receipts in the future. Helpful strategies include:

• Scanning receipts immediately after purchase
• Using expense-tracking apps
• Storing documents in secure cloud storage
• Linking accounting software to bank accounts
• Keeping separate accounts for business expenses
• Hiring bookkeeping services for accurate receipt tracking

Digital recordkeeping ensures documentation is easy to retrieve if the IRS ever requests proof.

1. Can you be audited without receipts?

Yes. If the IRS audits your tax return and you cannot provide receipts, the agency may request other documentation such as bank statements or invoices to verify your deductions.

2. Am I in trouble if I get audited?

Not necessarily. An audit is a review of your tax return. Accurate records and cooperation usually resolve it without major issues.

4. What is the $600 rule?

The $600 rule generally refers to the reporting requirement for Form 1099-NEC, which businesses must issue to independent contractors who receive $600 or more during the year.

5. Can you claim $300 in donations without receipts?

Some taxpayers may claim up to $300 in charitable donations without itemizing deductions, but maintaining documentation such as bank records is still recommended.

6. What are the biggest tax mistakes people make?

Common mistakes include unreported income, unsupported deductions, mixing personal and business expenses, and calculation errors. Poor recordkeeping is a frequent cause of audits.

Being audited without receipts can be stressful, but it does not automatically mean you will lose every deduction you claimed.

The IRS often accepts alternative documentation, reconstructed records, and, in limited cases, reasonable estimates under the Cohan Rule.

However, the safest approach is always strong recordkeeping. Maintaining receipts, bank records, and digital documentation ensures that you can support your deductions if the IRS ever asks for proof.
