Check internal tax records against your tax returns. Look through your recent government tax receipts and compare these against your internal records regarding taxes paid and tax liabilities. In the U.S., keep tax receipts on hand for at least 7 years, as this is the statute of limitations on tax fraud.[17]

Create an audit report. Compile a list of your findings into a succinct audit report. An audit report is simply a document that summarizes the findings of your audit. It will state problems you found, improvements that were made, and areas that were working well.[18]
Since this is your own audit, this does not need to be a formal document, and should simply be a useful document that you can refer to for your own usage, or that you can show the IRS in the event that your business is audited.
