Did you know that if there are mistakes on your tax return, it can take longer to get your refund? Worse yet, you may owe additional tax. Many common errors can be avoided by going slowly as you walk through each step of preparing a tax return.

One example of a common mistake is not choosing the right filing status. You can avoid this mistake by using the Interactive Tax Assistant on IRS.gov to help you choose the right one. Not entering the Social Security numbers and names for you, your spouse, and any dependents exactly as they appear on everyone’s Social Security card is also a common mistake, so make sure you double-check those. If your name changed after getting married or divorced, be sure to update the information with the Social Security Administration before filing a tax return using your new name.

Another common problem is incorrectly claiming credits and deductions. This includes the Child Care Credit, the Premium Tax Credit, and the Special Standard Deduction for people who are senior citizens or blind. Another frequent error is incorrectly figuring out the taxable amount of IRA distributions, pensions or annuities, or Social Security benefits.

Math errors are common, as well as putting in the wrong routing or bank account number for the direct deposit of your refund, and forgetting to sign and date your return before mailing it. If you’re married and filing jointly, both spouses must file and date the return. If not, the IRS will have to send it to you for your signature.
