Each dependent reported on your tax return must have a valid SSN and full name matching what is on record in the IRS database and Social Security Administration.
Fix #1: Sign into your PriorTax account and make corrections to your dependents' SSNs and names on your rejection status page.
Fix #2: Sign into your PriorTax account. If the information you entered seems to be correct to the best of your knowledge, you may need to paperfile your tax return this year. You should also contact the Social Security Administration to make sure they have the correct information on file for your dependents.
