Audit-Proof Documentation: What the IRS Actually Requires

Bank and credit card statements alone do not substantiate your deductions. They show that a transaction happened, but they do not explain the business purpose behind it. Without context, a deduction is just a number with no story behind it and the IRS is looking for that story.

Here is what some proper documentation actually looks like:

• Mileage Logs- with the date, destination, business purpose, and miles driven. “Drove to client” is not enough detail to fit the bill. You can use a spreadsheet, mileage log book, or a mileage tracking app.

• Asset purchases- records showing the invoice, the date the asset was placed in service, and documentation of the business use percentage if it is used for both personal and business purposes.

• Payroll- Filed payroll reports, filed tax forms, and proof that payments were made. Payroll errors are a commonly audited area for small businesses.

• Meals- Receipts that show the date, total amount, who was present, and the business purpose of the meeting. A credit card charge alone is not what we’re looking for here.

• Home Office- Records that demonstrate the space is used exclusively and regularly for business, along with accurate square footage calculations for both the office and the total home.

The distinction matters more than most business owners realize. Organized books get you through tax season. Solid documentation gets you through an audit.
