The IRS Notes that the Top 10 Mistakes for 1040 Forms Are:
1. Taxpayer identification numbers or names for dependents don't match IRS or SSA records, resulting in exemptions being denied.
2. Dependent's last name reported incorrectly.
3. Taxpayer identification numbers or names for dependents don't match IRS or SSA records, resulting in denial of all or part of the child tax credit.
4. SSN for child(ren) who qualify for earned income credit don't match SSA records.
5. Nontaxable earned income from W-2's not included.
6. Primary SSN is incorrect or illegible.
7. Earned income credit is figured or entered incorrectly.
8. Name line is illegible or does not match IRS records.
9. Based on information reported, the IRS re-calculated the tax using the filing status for a single person.

Clearly, most errors made on tax returns are the result of incorrect social security numbers and names. It is therefore very important that you be certain that the information supplied is correct.
