Things You'll Need:
- A physician’s certification if you are totally and permanently disabled
- Schedule R if you file Form 1040
- Schedule 3 if you file Form 1040A
-
Step 1
Determine whether you qualify. You must be a U.S. citizen or resident and you must be either age 65 or older or totally and permanently disabled. If you are disabled you must have received disability income in order to qualify for the credit.
-
Step 2
Determine whether you meet the income limits. There are two limits – adjusted gross income and the total of your nontaxable social security and pension income. The limits are based on your filing status. These limits are subject to change each year. You can find the limits in the instructions for schedule R (Form 1040), Schedule 3 (Form 1040A), and in IRS Publication 524.
-
Step 3
If you qualify, decide whether you want the IRS to figure your credit or you prefer to do it yourself. If you prefer to figure the credit yourself, skip to step 5.
-
Step 4
If you want the IRS to figure your credit, attach Schedule R to your return if you use Form 1040 or Schedule 3 if you use form 1040A. Check the box for your filing status and age in Part I. Complete Part II and lines 11 to 13 in Part III if you are disabled. Enter “CFE” on the dotted line next to line 48 of Form 1040 or line 30 of Form 1040A. Skip the rest of these steps.
-
Step 5
If you prefer to figure the credit yourself, fill out the front of Schedule R if you file Form 1040 or Schedule 3 if you file Form 1040A.
-
Step 6
Fill out Part III of Schedule R or Schedule 3 to calculate your credit. Your credit is 15% of the amount by which your “initial amount” (a fixed amount based on your filing status and situation) exceeds the total of your nontaxable benefits plus half the amount by which your adjusted gross income exceeds a certain base amount.
-
Step 7
Carry forward your credit from Schedule R to line 49 on Form 1040, or from Schedule 3 to line 30 on Form 1040A.
