Checklist of Common Tax Return Errors

Before filing your return, make sure it's correct and complete. It's important that you review your entire return, even if you have someone else prepare it, because any errors may delay the processing of your return.

The following checklist may help you avoid common errors:

• Submitting your tax return electronically ensures greater accuracy than mailing your return. The e-file system often detects common errors and rejects your tax return, sending it back to you for correction. This could save you delays in processing your tax return.

• Did you clearly print your name, taxpayer identification number, and current address, including your ZIP code, directly on your return?
• Did you choose only one correct filing status? See What Is My Filing Status? at Link opens in a new windowhttps://www.irs.gov/help/ita/what-is-my-filing-status.
• Did you check the appropriate exemption boxes for your personal, spousal, and dependency exemptions?
• Did you enter the total number of exemptions? Review Link opens in a new windowPersonal/Spousal Exemptions and Link opens in a new windowDependency Exemptions to find out if you qualify.
• Did you enter the names and taxpayer identification numbers for everyone listed on your return? If using Social Security numbers, they must be entered exactly as those names and numbers appear on each person's Social Security card. If there have been any name changes, be sure to contact the Social Security Administration at SSA.gov, or call it at 800-772-1213.
• Did you enter your income on the correct lines?
• Did you calculate deductions and credits correctly, put them on the right lines, and attach the necessary forms or schedules?
• Did you put brackets around negative amounts?
• If you're taking the standard deduction and checked any box indicating either you or your spouse were age 65 or older or blind, did you find the correct standard deduction using the chart in the Form 1040 Instructions or the Form 1040A Instructions?
• Did you figure the tax correctly? If you used the tax tables, did you use the correct column for your filing status?
• Did you sign and date the return? If it's a joint return, did your spouse also sign and date the return?
• If you received an IP PIN (Identity Protection PIN) from the IRS, see "Identity Protection PIN" in the instructions for your form and Link opens in a new windowThe Identity Protection PIN (IP PIN) page.
• Do you have a Form W-2 from each of your employers, and did you attach Copy B of each Form W-2 to your return? If you have more than one job, combine the wages and withholdings from all Forms W-2 you received, and report those amounts on one return.
• Did you attach each Form 1099-R that shows federal tax withholding?
• Did you attach all other necessary schedules and forms in the order of the sequence number shown in the upper right-hand corner?
• Did you use the correct mailing address from your tax form instructions?
• Did you use the correct postage on the envelope?
• If you owe tax, did you enclose a check or money order made payable to the "United States Treasury" with your return and include your name, address, Social Security number, daytime telephone number, tax form, and tax year on the payment?
• If you're due a refund and requested direct deposit, did you double-check your routing and account numbers for your financial institution?
• Did you make a copy of the signed return and all schedules for your own records?
