Why doesn't my Social Security numbers show up as income on my tax return after I added them into the system?

Not all of your social security income is taxable.  Sometimes none of it is taxable. Have you entered all of your other income? If you look at line 6a of your 1040, you will see the amount you entered.  Line 6b will tell you the amount that is taxable. 

If you fall into the following, 85% of your social security is taxable income

• Single with income above $34,000
• Married Filing Jointly with income above $44,000
• Married Filing Separate regardless of income

If you fall into the following, 50% of your social security is taxable income

• Single with combined income between $25,000-$34,000
• Married Filing Jointly with combined income between $32,000 and $44,000

If less than $25,000 and not married filing jointly, it would not be included as taxable income. 

Your combined income is calculated by adding your

• AGI plus
• Nontaxable Interest plus
• 1/2 of your social security Benefits
