My W2 income is 4.5 times higher than my 1099-misc income

[alissajade1998]

If my return on the W-2 would be almost twice as high as tax owed for 1099, why do I still owe to the IRS?

You cannot look at each piece of your income; that's not how it works.  It depends upon your overall picture: income, taxes withheld, deductions, credits, etc.
