Do I calculate Box 3 and Box 7 of my W-2 to total my taxable social security benefits?

[KatrinaB]

No. The income that would be included when calculating taxable social security benefits is the amount in Box 1 of your W-2. The amount in Box 1 is the amount of taxable income you have received for the year. This is the amount that the IRS uses to calculate taxable benefits.
