Your qualifying child’s full name, SSN, and DOB must match what is currently on file with the IRS e-file database and Social Security Administration.
Fix #1: Sign into your RapidTax account to doublecheck that each child’s name, SSN and DOB are correctly reported. If not, update as per the instructions shown on your rejection status page.
Fix #2: If the information you provided seems to be correctly entered to the best of your knowledge, then you may need to paperfile your tax return for this year and contact the Social Security information as soon as possible to update this information.
