The IRA audits help ensure that the businesses are paying the right amount of taxes to the department, and if the business is honest on its tax return and maintains accurate inventory records, then the IRS isn’t likely to find any issues during the audit process.

What is an IRS Audit?
The Internal Revenue Service audits businesses to make sure that they are accurately reporting their income and deductions, and are paying the proper amount of taxes to the authorities, and are complying with the tax laws. As per the law, all public companies, whether they are large private companies, financial institutions, non-profits, or government agencies, must be audited annually by independent auditors.
As per the official site “The IRS examines (audits) tax return to verify that the tax reported is correct.”
The IRS department selects the organisation for the audit through the help of different methods like internal and external referrals, statistical formulas, and pure random selection. If the business has been selected by the IRS for an audit, then the IRS will send the notice in the mail.

How the IRS Selects the Returns for the Audit
The Process of an IRS audit begins with the return selection, which is far more efficient than people understand. The IRS agency does not choose returns randomly to audit; they use refined computer algorithms and specific selection criteria for identifying the return with the highest chances of additional tax collection.
“Selecting a return for examination does not always suggest that the taxpayers has either made the error or been dishonest. In fact, some examinations result in a refund to the taxpayer or acceptance of the return without change.” stated in the examination (Audit) process of IRS.
Discrimination Information Function Scoring
It mainly signifies the primary selection method for most of the audits. It is a computer system that assigns the scores to the tax returns on the basis of the statistical formulas that compare your income, deductions, and overheads to those of similar taxpayers.
Income matching discrepancies
The inconsistencies in the income affect many audits as the information on your return does not match the third-party reports. If your Form 1040 demonstrates a different income amount than the 1099s and W-2s that the IRS has received, then their system will automatically show the difference.
Related examination selection
It takes place when your return is linked to the other audit. If your spouse or business partner gets audited, then there are chances that the IRS department can examine your return as well to ensure uniformity in the related transactions.
Information tips and Referrals
The information tips and the referrals can also affect audits, as they can occur from past employees, business associates, whistleblowers, or even through observation during other government inquiries.
The Audit Timeline
The process of an IRS audit follows the predictable timelines through the specific duration that is based on the type of audit, complexity, and how quickly you respond to the IRS requests.
- The initial contact mainly occurs within 12-24 months after you file your return. The IRS department needs some time to process the return, match the third-party data, and run its selection procedures.
- The examination phase time differ based on the audit type. The correspondence audits mainly take around 3-6 months, the office audits can be completed within 2-3 months, and the field audits can take around 6-18 months.
- After the examination phase ends, the resolution phase begins. If the IRS proposes to get changed, then you have 30 days to agree, disagree, or request an appeal conference.
Understanding this timeline is important as it will help to plan suitably and avoid decisions that can extend the audit process unreasonably.
Your Rights during the audit process
- Right to professional representation: It means that you can have a tax professional represent you at the time of the audit. In most cases, you do not have to meet the IRS personally; your representative will handle the meeting and communication on your behalf.
- Right to understand the audit: It requires the IRS to explain why they have selected your return, what items they are inspecting, and what documents are needed by them.
- Right to privacy and confidentiality: It means that the IRS can inspect only the items that are applicable to analyzing the correct tax liability.
- Right to reasonable examination: It requires the IRS to conduct the audits at a reasonable time and place. They cannot demand the meeting at inconvenient times or at a location without a good reason.
Documentation Requirements
The success of the IRS audit process mainly depends on providing clear and organised documentation that can support your tax return positions. The quality and the organisation of your records often govern the audit outcomes more than the fundamental facts.
| Contemporary records | The contemporary records can carry more weight compared to the reconstructed documentation. The IRS prefers the records that are created at the time when the transaction takes place, rather than summaries or recreated documents that are prepared for the audit. |
| Complete Documentation | Providing the complete documents is important for the smooth audit process, as it provides all the requested items in the format required. The partial or the substituted document can develop additional questions and can extend the timeline. |
| Business purpose documentation | The business purpose documentation is important for the business deduction as it helps the IRS to understand what you have spent and why these expenses are important for your business, and how it is related to the income production. |
| Charitable deduction | For the charitable deduction, it is important to provide the written acknowledgment from the organizations, electronic payment confirmation, or cancelled checks, and evidence of the business’s tax-exempt status. |
| Business expenses | For the business expenses, you have to organise the receipts chronologically with a brief description of the business purpose. You should also include the supporting documents, like invoices, contracts, and business meeting notes, which can create a link to the income-producing activities. |
| Travel expenses | For the Travel expenses, you have to maintain detailed records that display the dates, business purposes, destination, and costs. The mileage logs for the vehicle expenses should include the destinations, dates, odometer readings, and the purpose of the business for each trip. |
