6 Tax Deductions and Credits That Can Attract IRS Scrutiny

Not every tax break works the same way. Some are easy to claim, while others come with detailed rules that are easy to misread. If those rules are not followed carefully, the outcome may be more than a reduced refund. It can lead to an IRS notice, penalties, or even a tax bill that requires money to be paid back.

The encouraging part is that these deductions and credits are legitimate when they are claimed correctly. The challenge is that many taxpayers do not know exactly where the boundaries are, which makes it important to avoid costly mistakes.

1. The home office deduction

The home office deduction has a long-standing reputation for drawing IRS attention. That reputation is often overstated, but the deduction still has strict rules. One of the most common mistakes is assuming W-2 employees can generally claim it on their federal return, when they usually cannot.

2. Charitable deductions for non-cash donations

Giving away clothing, furniture, or other household items may seem simple, but the hard part is figuring out value and keeping proper records.

Many taxpayers assign donated items a value that is too high. The IRS requires fair market value, not the amount originally paid. A sofa that is several years old is not worth its original price. If non-cash donations exceed $500, Form 8283 must be filed. For items worth more than $5,000, a qualified appraisal is usually required.

The IRS often checks for inflated values, missing receipts, and the absence of written acknowledgment for donations of $250 or more. Keeping detailed records and taking photos of donated items can help protect your claim.

3. Business meal deductions

Business meals can be deducted, but not automatically. In most cases, they are 50% deductible. The expense must be ordinary and necessary for the business, cannot be lavish or extravagant, and you must be present.

A common error is deducting meals that are mostly social or that have no clear business purpose. In those cases, the IRS may look for proof of who attended, why the meal was tied to business, and receipts supporting the amount claimed.

Adding a short note to the receipt about the purpose of the meeting can be helpful if questions come up later.

4. Education credits

Education credits such as the American Opportunity Credit (AOTC) and the Lifetime Learning Credit can be highly valuable, but they also come with income limits, enrollment rules, and restrictions on eligible expenses.

One common mistake is claiming a credit for expenses already covered by tax-free scholarships or employer assistance. You cannot claim the same expense twice. Another problem is claiming the credit for a student who does not qualify, such as someone enrolled less than half-time for the American Opportunity Credit.

The IRS checks Form 1098-T information, income eligibility, and how scholarships and grants were applied. Because the American Opportunity Credit is partly refundable, it often receives extra scrutiny.

5. Casualty and theft losses

Casualty losses are no longer broadly deductible. In general, they apply only to losses in federally declared disaster areas. Some taxpayers still try to deduct damage from events that do not qualify, such as a burst pipe or local flooding that was not part of a declared disaster.

Even when a loss does qualify, it usually must clear the $100-per-event threshold and exceed 10% of adjusted gross income before it can be deducted. The IRS may also look for proof that the loss happened in a declared disaster area, correct adjustments for insurance reimbursements, and accurate estimates of property value before and after the event.

These rules are technical, and even small mistakes can cause a claim to fail.

6. Earned Income Tax Credit

The Earned Income Tax Credit (EITC) is one of the most valuable credits for low- and moderate-income workers, but it is also one of the most frequently audited. Common errors include claiming a child who does not meet residency rules, misreporting income, or misunderstanding the eligibility rules for self-employment income.

Because the credit can be substantial, the IRS reviews eligibility closely. It looks for proof that qualifying children lived in the home, accurate income reporting, and the correct filing status.

Claimed properly, the credit can provide meaningful help. Claimed incorrectly, it can lead to repayment and temporary loss of eligibility.

Bottom line

These tax breaks are real, and millions of Americans claim them each year without problems.

Before you claim a deduction or credit, take a few minutes to review the requirements and make sure your records back up the claim. Avoiding penalties can help protect your financial footing.

If you are unsure, a qualified tax preparer can help you work through the details and stay within the rules.
