I have soc. sec. disability income as my only source of income. I have custody/guardianship of my 12-yr-old grandson. Is there any way for me to file taxes and get $ back? i.e.: child tax credit, earned income credit, etc.

From the IRS site for Child Tax Credit:

For this purpose, earned income includes only:
Taxable earned income, and
Nontaxable combat pay.


For the Earned Income Credit from the IRS site:

Disability Benefits

Disability retirement benefits are considered earned income until you reach minimum retirement age. Minimum retirement age is the earliest age you could have received a pension or annuity if you were not disabled.

After you reach minimum retirement age, the payments are taxable as a pension and not considered earned income.

Benefits such as Social Security Disability Insurance, SSI, or military disability pensions are not considered earned income and thus, cannot be used to claim the Earned Income Tax Credit (EITC). You may qualify for the credit only if you, or your spouse, also have earned income.

It all hinges upon your actual age if you would be eligible to file for this tax credit.
