From gross pay to take-home pay
Three separate tax bills sit between the gross salary and the bank account: federal income tax, FICA, and state income tax. For Computer and Information Systems Managers earning the Williamson County, TX median of $176,990, they add up to $45,029.

Put another way, of every $100 earned, about $25 goes to taxes and $75 reaches the paycheck. The overall effective tax rate is 25.4%.
Federal income tax
After the $15,750 standard deduction, taxable income is $161,240. Federal brackets are marginal, so only the slice of income above each threshold is taxed at the higher rate; the last dollars of this salary fall in the 24% bracket. The resulting federal income tax is $31,545, an effective 17.8% of gross pay, well below the 24% marginal rate because the lower brackets are cheaper.
Social Security and Medicare (FICA)
Payroll taxes are a flat percentage of wages. Social Security takes 6.2% up to a wage base of $176,100, which costs $10,918 on this salary, the maximum for the year because pay exceeds the cap. Medicare takes 1.45%, or $2,566. FICA totals $13,485, which is 7.6% of gross pay.
State income tax in Texas
Texas does not tax wage income, so the state income tax line for Computer and Information Systems Managers in Williamson County, TX is $0. That alone leaves more in the paycheck than the same salary would in a state with an income tax. For scale, a hypothetical flat 5% state tax on this salary would cost about $8,850 a year, so the absence of a state tax is worth roughly $737 a month.
