One common mistake is not choosing the right filing status. You can avoid this mistake by using the IRS’ Interactive Tax Assistant on IRS.gov to help you choose the right one.
Another common mistake is not entering the correct Social Security numbers and names for your spouse and any dependents you’re claiming exactly as they appear on everyone’s Social Security cards.
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 problem is incorrectly claiming credits and deductions. This includes things like 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, and annuities, or Social Security benefits.
Be sure not to use the wrong routing or bank account number for the direct deposit of your refund.
