Why is the income total different from what I entered to what was used to calculate my taxes?

[48kmcu58]

My income totaled $100,604 but the amount used to calculate my taxes owed was $97,680.   What is the $2,924 difference?

Can you tell us what makes up the $100,604?

W-2s, 1099-Rs, SSA-1099

[Anita01 · Accepted solution]

The SSA-1099 is for Social Security, and up to 85% of that income can become taxable, based on the amount of your other income. You would not expect to see all of your Social Security included in your taxable income.
