Most taxpayers who end up in trouble with the IRS are not trying to cheat. They are busy business owners, self-employed professionals, and families who made a few common tax mistakes. Over time, those mistakes turn into IRS notices, audits, penalties, and tax debt that can feel impossible to escape.
As a former IRS Revenue Agent with nearly two decades of experience, Gwendolyn A. Hodge, CPA, saw the same errors again and again. Her new book, Dodging the Tax Bullet, launching October 29, 2026, shares that insider knowledge in plain language so you can avoid an IRS audit, protect your money, and stay in good standing. Here are some of the most common mistakes the book covers, and how you can dodge them.
Why Honest Taxpayers End Up on the IRS Radar
The IRS uses computer matching, data analytics, and trained examiners to spot returns that do not add up. It compares the income you report against the forms third parties send, and it looks for deductions that seem out of line for your business or income level. Small errors can raise red flags, such as:
- Income that does not match your W-2s and 1099s,
- Deductions that are unusually high for your industry,
- Round numbers and estimates instead of actual records, and
- A lifestyle that does not fit the income you report.
Understanding these IRS audit triggers is the first step toward staying out of trouble.
Income Reporting Mistakes That Lead to IRS Notices
Leaving Income Off Your Return
Many people believe cash payments, payment app transfers, or side-gig income do not need to be reported. They do. All income is taxable unless the law specifically excludes it. The IRS receives copies of your Forms W-2, 1099-NEC, 1099-K, and 1099-MISC, and its systems match them against your tax return. When the numbers do not match, you can expect a CP2000 notice proposing additional tax, penalties, and interest.
To avoid underreported income problems:
- Report All Sources of Income: Include cash sales, tips, payment app receipts, gig work, and freelance income, even if you never received a 1099.
- Reconcile Your Bank Deposits: Compare your deposits to your reported gross receipts before you file, so you can explain any differences.
- Keep Copies of Every Information Return: Save each W-2 and 1099 you receive and confirm that each one is reflected on your return.
Living Beyond Your Reported Income
When your lifestyle does not match your tax return, the IRS notices. A new home, luxury vehicles, or frequent travel paired with modest reported income can lead to a lifestyle audit, also called a financial status audit. In these audits, examiners review bank deposits, spending, and assets to determine whether income is missing from your return. For cash businesses, this type of review is especially common.
Deduction and Recordkeeping Mistakes That Cost You at Audit
Poor Recordkeeping
In an IRS audit, the burden is on you to prove the income and expenses on your return. Without records, a legitimate deduction can be disallowed. Strong recordkeeping habits include:
- Keeping business and personal funds in separate bank accounts,
- Saving receipts, invoices, and bank statements for at least three years,
- Maintaining a written mileage log for business use of your vehicle, and
- Recording daily cash sales and deposits if you run a cash business.
Writing Off Personal Expenses on Schedule C
Family vacations, personal vehicles, groceries, and dinners with friends are not business expenses. Deducting personal expenses on Schedule C is one of the fastest ways to draw an auditor’s attention, and it can lead to additional tax, accuracy-related penalties, and interest. A good rule of thumb: if you would have spent the money even without your business, it is likely not deductible.
Claiming Dependents Who Do Not Qualify
The rules for claiming dependents are strict. They consider the person’s relationship to you, age, residency, and financial support. Claiming someone who does not qualify can lead to the loss of valuable credits, such as the Child Tax Credit and Earned Income Tax Credit, along with repayment and penalties. When more than one person could claim the same child, the IRS tie-breaker rules decide who is eligible.
Business Owner Mistakes With Serious Consequences
Mishandling Payroll Taxes
When you withhold income tax, Social Security, and Medicare from employee paychecks, that money belongs to the government. Using withheld payroll taxes to cover rent, suppliers, or other bills is one of the most serious mistakes a business owner can make. The IRS can assess the Trust Fund Recovery Penalty personally against owners and other responsible persons, putting personal assets at risk even when the business is incorporated.
Misclassifying Workers as Independent Contractors
Paying workers on a 1099 instead of a W-2 may seem like a way to save money, but worker misclassification can result in back payroll taxes, penalties, and interest. The IRS looks at the full relationship between you and the worker, including:
- Behavioral Control: Whether you control what work is done and how it is done.
- Financial Control: Whether you control the business side of the job, such as how the worker is paid, whether expenses are reimbursed, and who provides tools and supplies.
- Relationship of the Parties: Whether there are written contracts, employee-type benefits, and an expectation that the relationship will continue.
If you control how, when, and where someone works, the IRS may consider that person an employee.
Filing and Follow-Through Mistakes That Make Problems Worse
Even when your return is accurate, how you file and respond to the IRS matters. Common mistakes include:
- Filing Late: The failure-to-file penalty is generally 5% of the unpaid tax for each month the return is late, up to 25%. Filing on time, even if you cannot pay in full, keeps this penalty from growing.
- Relying Only on DIY Tax Software: Tax software is only as accurate as the information you enter. It cannot tell you whether a worker is an employee, whether an expense is personal, or whether a dependent truly qualifies.
- Ignoring IRS Notices: IRS letters come with deadlines, and missing them can cost you appeal rights and lead to liens and levies. Opening every letter and responding on time is essential.
