Errors on tax returns delay the processing of your return and often, your refund. Avoid these common errors: 

1. Incorrect Recovery Rebate Credit - The Recovery Rebate Credit is for people who did not receive a stimulus payment in 2008 or who did not receive all they were due. To avoid delays in refunds, taxpayers must know whether they received a payment in 2008 and the correct amount of that stimulus payment.
2. Incorrect or missing Social Security number - Enter exactly as it is on the Social Security card.
3. Incorrect or misspelling of dependent's last name - Enter exactly as it appears on the Social Security card.
4. Filing status errors - Make sure you choose the correct filing status for your situation.
5. Math errors - Make sure all addition and subtraction is correct. Remember, when you file electronically, the software takes care of the math for you.
6. Computation errors - Take your time. Many taxpayers make mistakes when figuring taxable income, withholding and estimated tax payments, Earned Income Credit, Standard Deduction for age 65 or over or blind, the taxable amount of Social Security benefits, and child and dependent care credit.
7. Incorrect bank account numbers for Direct Deposit - Double-check any bank account numbers you provide.
8. Forgetting to sign and date the return - An unsigned tax return is like an unsigned check - it's invalid.
9. Incorrect Adjusted Gross Income information - If you e-file this year, and you also e-filed last year, you'll need to verify your identity to the IRS by providing your 2008 AGI or PIN.
