Common Tax Return Mistakes to Avoid

Mistakes happen. The good news is that most tax return errors are easy to avoid with a quick review before you file. Even if a preparer completes your return, you’re still the one responsible for what’s reported.

Here are some of the most common issues we see.

Filing before you have every tax form

Before you file, make sure you’ve received all your income documents, like W-2s, 1099s, interest statements, and any other tax reporting forms. Missing one can mean an amended return later.

Tip: Your IRS Online Account is one of the easiest ways to review your tax records.

Choosing the wrong filing status

Your filing status affects your tax rate, standard deduction, and eligibility for certain credits. Pick one status and make sure it’s the right one for your situation. Consult your tax advisor if you are uncertain about which filing status applies to you.

Entering the wrong income amounts

Double-check wages, dividends, bank interest, retirement income, and any other income. A single digit off can create problems or slow processing.

Misspelled names or missing Social Security numbers

Every name and taxpayer ID number on the return must match Social Security records. Enter names exactly as shown on each Social Security card. If a name changed recently, update it with the Social Security Administration.

Missing or miscalculating credits and deductions

Tax rules change, and some credits and deductions shift year to year. Make sure you qualify, the math is right, and you have the documentation to support what you claim.

Forgetting to sign the return

An unsigned return is considered invalid. For joint returns, both spouses generally must sign and date the return. Some exceptions apply, such as certain military situations or a valid power of attorney.

Using incorrect direct deposit information

If you’re expecting a refund, a direct deposit to your bank account is usually the fastest option. Ensure the routing number and account number are correct before submitting.

Filing electronically helps catch errors

E-filing reduces common mistakes because the system checks for missing information and other issues before the return is accepted. If something doesn’t match, it can be rejected and sent back for correction, which may help avoid longer delays.
