If your return is rejected with IRS rejection code R0000-902, the taxpayer identification number (TIN) for the primary taxpayer has already been used on a return filed with the IRS. In most cases, the taxpayer's social security number (SSN) was entered incorrectly.
To fix this error and refile:
From within your TaxACT return (Online or Desktop) click on the Basic Info tab
Click Personal Info directly below the tabs
On the following screen, verify that your entries match the information on your social security card. If necessary, click Continue and verify that the same SSN was not accidentally entered for your spouse.
After fixing any errors, click the Filing tab and repeat the steps to e-file your return. You have not resubmitted until you click the green Submit button.
If you do not find any errors, contact the Social Security Administration at 1-800-772-1213 to verify that your information matches their file.
