You may qualify for a tax credit for 2012 if your income is quite low and you meet one of the following conditions:
You will not be able to claim a credit if your Social Security benefits or adjusted gross income is too high, or if you have no tax liability (34.9).
You are considered permanently and totally disabled if you are unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or that has lasted or can be expected to last for a continuous period of not less than 12 months.
For the first year you claim the credit, you need a physician’s certification of your disability. For later years, new certifications are generally not required.
You may not claim the credit if you are a nonresident alien at any time during 2012, unless you are married to a citizen or resident and you have elected to be treated as a resident (1.5).
The amount of the credit is 15% times the base amount after reductions. The base amount for the credit is generally $7,500, $5,000, or $3,750 (34.8). The base amount is reduced by nontaxable Social Security and other tax-free pensions, as well as by adjusted gross income exceeding specific limits (34.9).
The credit is not refundable. That is, it is allowed only up to your tax liability (34.9).
You claim the credit on Schedule R if you file Form 1040 or Form 1040A. You may not claim the credit on Form 1040EZ.
A married couple may claim the credit only if they file a joint return. However, if a husband and wife live apart at all times during the taxable year and file separately, the credit may be claimed on a separate return.
