I am dependent of my mom and the form is asking for her SSN and I don't have it can I skip this part?

[DoninGA]

The program would not ask for the SSN of the parent who is claiming you as a dependent unless you are were entering unearned income (interest, dividends, or capital gains) of $2,700 or more on your tax return.  And it is taxed at the parent's rate if the parent's rate is higher than the child's.

What income are you entering on your tax return?

No. In most cases, you will need to give your mom's Social Security number because she's claiming you as a dependent. It's also a requirement to prove your dependency status.

If your mom has an Individual Taxpayer Identification Number (ITIN), she should use it in the proper field instead.

If you need more time to get the SSN for your mom, you can get an automatic 6-month extension by filing the Form 4868:

 If your mom isn't eligible for an SSN, she may need to apply for an ITIN. Open the link below to see how to apply for this number:
