Common Mistakes People Make on Their Tax Returns (And How to Avoid Them)
Avoid delays, penalties, and missed refunds with these smart tips.
Filing your taxes might not be your favorite time of year—but it’s a crucial one. Unfortunately, even small mistakes on a tax return can lead to big headaches: processing delays, smaller refunds, audits, or even penalties from the IRS. The good news? Most common tax errors are completely avoidable.
At Stress Less Insurance & Tax, we’ve seen it all—and we’re here to help you steer clear of these common filing mistakes so you can file with confidence.
1. Incorrect or Missing Personal Information
It may sound simple, but one of the most frequent mistakes is entering incorrect Social Security numbers, misspelled names, or wrong birthdates—especially for dependents.
✅ Tip: Double-check all personal info before filing. Make sure names match exactly what’s on the Social Security card.
2. Filing Status Errors
Choosing the wrong filing status—such as “Head of Household” instead of “Single”—can lead to incorrect tax liability and refund amounts. It can also raise red flags during audits.
✅ Tip: Not sure which status applies? Ask a tax professional or use IRS tools to clarify. Filing jointly or separately can also affect your refund if you’re married.
3. Forgetting to Report All Income
It’s not just your W-2s. You must also report:
Freelance or gig work (1099 forms)
Unemployment income
Interest and dividends
Cryptocurrency transactions
Missing even a small source of income can result in penalties.
✅ Tip: Keep a checklist of all income sources and watch for 1099s in the mail—or electronically.
4. Overlooking Deductions and Credits
Many people miss valuable deductions and credits simply because they didn’t know they qualified. Commonly overlooked tax breaks include:
Education credits
Medical expense deductions
Earned Income Tax Credit (EITC)
Child and Dependent Care Credit
Retirement savings contributions
✅ Tip: Keep good records throughout the year and ask your tax preparer about deductions based on your lifestyle and work.
5. Math and Calculation Errors
Even with tax software, math errors can still happen—especially when entering figures manually. These mistakes can result in incorrect refunds or balances due.
✅ Tip: Use trusted software or a professional tax preparer who double-checks all figures before submitting.
6. Bank Account Mistakes for Direct Deposit
Direct deposit is the fastest way to get your refund, but if your bank account or routing number is wrong, your refund could go to the wrong place—or get delayed.
✅ Tip: Triple-check your bank information before filing. Even one wrong digit can cause a refund mishap.
7. Missing the Filing Deadline
Failing to file on time—especially if you owe—can lead to late fees and interest charges. Even if you can’t pay your full balance, filing on time is always better than ignoring it.
✅ Tip: Mark the deadline (usually April 15) and set reminders. If needed, file for an extension—but remember, an extension to file is not an extension to pay.
8. Not Keeping Copies of Your Return
After you file, you’ll need a copy of your return for future reference, especially if you’re applying for loans, financial aid, or making corrections later.
✅ Tip: Save a digital and/or printed copy of your return, W-2s, 1099s, and receipts in a secure place for at least 3–7 years.
✅ Tip: Mark the deadline (usually April 15) and set reminders. If needed, file for an extension—but remember, an extension to file is not an extension to pay.
9. DIY Filing Without Understanding the Rules
Tax software can be helpful, but it doesn’t catch every mistake—especially if you’re self-employed, have dependents, or are claiming multiple deductions.
✅ Tip: If your taxes are anything more than basic, working with a professional can help ensure accuracy, maximize your refund, and reduce your stress.
