What do people forget to claim on taxes?

Little-Known Tax Deductions You Might Be Missing

When tax season rolls around, most people focus on the basics—mortgage interest, charitable donations, maybe a home office deduction. But there’s a long list of often-overlooked expenses that could put money back in your pocket.

One common miss? Work-related living costs. If you’ve taken a temporary assignment away from home—say, a few weeks or months in another city—some of your living expenses might be deductible. Think lodging, meals, and even transportation if it’s directly tied to your job.

Another area many forget: mobile and internet bills. If you regularly use your phone or internet for work—especially if you're self-employed or not fully reimbursed—you can claim a portion based on business use. The same goes for specialized tools or software required for your job. A graphic designer’s tablet, a contractor’s measuring equipment, or a subscription to a trade publication often qualify.

Even accessories linked to work gear can count. Did you buy a case for that work phone or a headset for video calls? Those small items add up. And yes, while it might sound odd, some pet expenses are deductible—but only in very specific scenarios. For example, if you’re a farmer using working dogs or a writer with a service animal, those costs may be legitimate. But be careful: personal items, like adult toys, are only deductible if used strictly for business purposes—such as in a retail resale operation.

The key is documentation. Keep receipts, logs, and records that clearly tie the expense to your work. The IRS isn’t out to catch honest filers—but they do want proof.

Before you file, take a second look. Sometimes the biggest savings come in the smallest, most unexpected forms.
