Avoid These Small Business IRS Audit Mistakes
Businesses that are slowly emerging from the COVID-19 pandemic should now keep their eye on another looming obstacle: IRS audits. In late 2020, the IRS announced that it will increase tax audits of small businesses by 50 percent in 2021. Here are several mistakes to avoid if you do get audited by Uncle Sam.
- Mistake: Missing income. A long history of investigating has led IRS auditors to focus on under-reported income. If you’re a business that handles cash, expect greater scrutiny from the IRS. The same is true if you generate miscellaneous income that’s reported to the IRS on 1099 forms. Be proactive by tracking and documenting all income from whatever source. Invoices, sales receipts, profit and loss statements, bank records—all can be used to substantiate income amounts.
- Mistake: Higher than normal business losses. Some small businesses struggle in the early years before becoming profitable. If your company’s bottom line never improves, the IRS may view your enterprise as a hobby and subsequently disallow certain deductions. As a general rule, you must earn a profit in three of the past five years to be considered a legitimate business.
- Mistake: Deductions lacking substantiation. Do you really use your home office exclusively for business? Does your company earn only $50,000 a year but claim charitable donations of $10,000? Do you write off auto expenses for your only car? The key to satisfying auditors is having clear and unequivocal documentation. They want source documents such as mileage logs that match the amount claimed on your tax return and clearly show a business purpose. If you can’t locate a specific record, look for alternative ways to support your tax return filings. In some cases, a vendor or landlord might have copies of pertinent records.
- Mistake: No expense reports. If you use your credit card for business, create an expense report with account numbers and attach it to each statement. Then attach copies of the bills that support the charges. This is an easy place to blend in personal expenses with business expenses and auditors know it.
- Mistake: No separate books, bank accounts or statements. Never run personal expenses through business accounts and vise versa. Have separate bank accounts and credit cards. A sure sign of asking for trouble is not keeping the business separate from personal accounts and activities.
- Mistake: Treat the auditor as an enemy. Auditors have a job to do, and it’s in your best interest to make their task as painless as possible. Try to maintain an attitude of professional courtesy. If you’re called to their office, show up on time and dress professionally. If they come to your place of business, instruct staff to answer questions honestly and completely.

Do’s and don’ts for taxpayers who get a letter or notice from the IRS
The IRS mails letters or notices to taxpayers for a variety of reasons including if:
- They have a balance due.
- They are due a larger or smaller refund.
- The agency has a question about their tax return.
- They need to verify identity.
- The agency needs additional information.
- The agency changed their tax return.
Here are some do’s and don’ts for taxpayers who receive one:
- Don’t ignore it. Most IRS letters and notices are about federal tax returns or tax accounts. The notice or letter will explain the reason for the contact and gives instructions on what to do.
- Don’t panic. The IRS and its authorized private collection agencies generally contact taxpayers by mail. Most of the time, all the taxpayer needs to do is read the letter carefully and take the appropriate action.
- Do read the notice. If the IRS changed the tax return, the taxpayer should compare the information provided in the notice or letter with the information in their original return. In general, there is no need to contact the IRS if the taxpayer agrees with the notice.
- Do respond timely. If the notice or letter requires a response by a specific date, taxpayers should reply in a timely manner to:
- minimize additional interest and penalty charges.
- preserve their appeal rights if they don’t agree.
- Do pay amount due. Taxpayers should pay as much as they can, even if they can’t pay the full amount. People can pay online or apply for an Online Payment Agreement or Offer in Compromise. The agency offers several payment options.
- Do keep a copy of the notice or letter. It’s important to keep a copy of all notices or letters with other tax records. Taxpayers may need these documents later.
- Do remember there is usually no need to call the IRS. If a taxpayer must contact the IRS by phone, they should use the number in the upper right-hand corner of the notice. The taxpayer should have a copy of their tax return and letter when calling. Typically, taxpayers only need to contact the agency if they don’t agree with the information, if the IRS request additional information, or if the taxpayer has a balance due. Taxpayers can also write to the agency at the address on the notice or letter. If taxpayers write, they should allow at least 30 days for a response.
- Do avoid scams. The IRS will never contact a taxpayer using social media or text message. The first contact from the IRS usually comes in the mail. Taxpayers who are unsure if they owe money to the IRS can view their tax account information on IRS.gov.
