The Most Common Mistakes People Make on Their Tax Returns

And How You Can Avoid Them This Year

Filing your tax return might feel like just another task on your to-do list — but even one small oversight can lead to penalties, delays, or missed refunds. At Khob Tax, we’ve seen it all. And more often than not, the biggest tax issues stem from surprisingly common mistakes — especially for self-employed individuals and sole proprietors.

Let’s walk you through the most frequent ones — and how to steer clear of them.

Mistake #1: Guessing Instead of Confirming

A lot of people go off memory when entering income figures, forgetting things like freelance work, side gigs, or rental income.
Even one missed 1099-NEC form or 1099-INT from Bank can trigger an IRS notice.

Pro Tip: Wait until you’ve received all income forms — including 1099 NEC reporting for non-employee compensation — before filing. Self-employed? Keep a record of every payment, no matter how small.

Mistake #2: Misreporting Self-Employment Income

Self-employed income reporting is one of the most mishandled areas on tax returns. Many business owners underreport or skip eligible deductions — like home office expenses, mileage, or software subscriptions.

Pro Tip: Our Self-Employed Income Tax Reporting Guide ensures your return is accurate and optimized — especially if you’re filing as a sole proprietor in Fremont, Dublin, or Milpitas. We specialize in:

• Sole proprietorship tax return in Milpitas
• Self-employed tax filing in Fremont
• Small business tax return in Dublin

Mistake #3: Not Reporting Foreign Income

If you earn income outside the U.S., you must declare it — even if it’s taxed abroad. Many filers are unaware that failing to report global earnings can result in serious penalties.

Pro Tip: Our experts will show you How to Report Foreign Income on Taxes, navigate FBAR requirements, and avoid legal trouble.

Mistake #4: Rushing or Delaying Your Filing

Filing too fast can cause you to miss key deductions. Filing too late could mean penalties, missed refunds, or stress.

Pro Tip: Schedule early with a Professional Tax Consultant in the Bay Area like Khob Tax. We’ll help you get organized without the pressure.

Mistake #5: Confusing Tax Classifications

Many new business owners don’t know whether they’re supposed to file as a sole proprietor, LLC, or S Corp. Even worse, they may file under the wrong classification.

Pro Tip: If you’re unsure whether your sole proprietor tax filing is done correctly — or if your 1099-NEC tax reporting was handled right — we’re here to help.
