If your name, SSN, and birth date do not match the database, your tax return will be returned for correction and you'll have to visit the Social Security Administration's office. If you are filing Forms 40 or 43 you must attach a copy of your federal return and schedules. Make sure you take the right standard deduction and tax table amount for the filing status you are claiming. One of the most common holdups we see is caused by simple addition and subtraction errors. Please check your math.
Unsigned returns are the other most common cause for delay.
