If your return is rejected with IRS rejection code R0000-902-01, 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.
Is your Social Security correct on your tax return?
Do you know if someone else may have entered you on their tax return as a dependent?
