Hi and welcome to Just Answer!
First of all - we need to determine if any of your social security benefits are taxable - here is a simple test - take half of your social security benefits plus other taxable income - if the total is less than $25,000 (for singles) - none of your social security benefits is taxable. Thus your only taxable income is $14,000 (other income besides social security benefits).
There are filing requirements – please see for reference IRS publication 501 – page 3 - 2010 Filing Requirements Chart for Most Taxpayers - http://www.irs.gov/pub/irs-pdf/p501.pdf
Thus, if you are single and below 65 – you generally must file your tax return if your taxable income is above $9350. So because your taxable income is $14,000 - you are required to file.
Thank you very much. That is all I need to know
