Gross and Net Salary: Why I Don't Like Taxes

    My gross salary is $250,000. First I took out federal taxes. I am in the $15,454-$33,379 tax bracket, assuming I get paid a monthly (giving me a $20,833.33 paycheck). The taxes for $15,454 are $3,716.95, so I added that to the required 33% of the money I made over $15,454. This 33% is taxed on $5379.33 for an additional $1,775.19. (This is what I add to $3,716.95 for a total of $3,550.36 monthly income tax.) My yearly income tax withholding is $42,604.32.
    Social security is a 6.2% withholding of a paycheck, but there is a cap where I stop paying the 6.2% on my income at $113,700. This makes for a total of $7,049.40 out of my paycheck for social security. Medicare is a 1.45% deduction on the total gross income, so that is a $3,625 deduction.
    So far, with federal income taxes paid and social security and Medicare payments withheld, I have $196,721.28. Using this amount, I filled out the 2012 TC-40 form, which is Utah's individual income tax return form. $9837 was deducted in state taxes. This leaves me with a yearly net income of $186,884.28.
