IRS: Top Tax Filing Mistakes to Watch Out For

Before you send out your returns by the April 17 deadline, check for what the Internal Tax Revenue Service lists as the most common tax filing mistakes.

Rushing to make the April 17 tax filing deadline? But beware, these common tax filing mistakes can cause a lot of headaches, including expensive audits. 

  1. Incorrect or missing Social Security Numbers When entering SSNs for anyone listed on your tax return, be sure to enter them exactly as they appear on the Social Security cards.
  2. Incorrect or misspelling of dependent’s last name When entering a dependent’s last name on your tax return, ensure they are entered exactly as they appear on their Social Security card.
  3. Filing status errors Make sure you choose the correct filing status for your situation. There are five filing statuses: Single, Married Filing Jointly, Married Filing Separately, Head of Household, and Qualifying Widow(er) With Dependent Child. See Publication 501, Exemptions, Standard Deduction, and Filing Information to determine the filing status that best fits your needs.
  4. Math errors When preparing paper returns, review all math for accuracy. Or file electronically; the software can do the math for you.
  5. Computation errors Take your time. Many taxpayers make mistakes when figuring their taxable income, withholding and estimated tax payments, Earned Income Tax Credit, Standard Deduction for age 65 or over or blind, the taxable amount of Social Security benefits, and the Child and Dependent Care Credit.
  6. Incorrect bank account numbers for Direct Deposit If you are due a refund and requested direct deposit, review the routing and account numbers for your financial institution.
  7. Forgetting to sign and date the return An unsigned tax return is like an unsigned check – it is invalid. And, remember on joint returns both taxpayers must sign the return.
  8. Incorrect Adjusted Gross Income information Taxpayers filing electronically must sign the return electronically using a Personal Identification Number. To verify their identity, taxpayers will be prompted to enter their AGI from their originally filed 2010 federal income tax return or their prior year PIN if they used one to file electronically last year. Taxpayers should not use an AGI amount from an amended return, Form 1040X, or a math error correction made by IRS.
