From your tax return
Your Adjusted Gross Income (AGI)
+any non-taxable interest
+50% of your social security benefits
If this total (on your married filing joint return) is greater than $32,000, your social security benefits are going to be taxed. The amount of the benefits is determined by how much your calculation above exceeds the $32,000. The worksheet I referenced above in the Form 1040 instructions, Page 32 will let you use your actual figures to determine the taxable amount.
