Frequently asked questions
What's the take-home on $100,000 in Texas?
For a single filer with no pre-tax contributions, take-home is approximately $78,980 per year — about $3,038 biweekly. Married filing jointly is higher due to wider brackets and a larger standard deduction.
Does this include state income tax?
Texas has no state income tax. The only deductions on your $100,000 are federal income tax, Social Security (6.2% up to the wage base), and Medicare (1.45% plus the 0.9% additional Medicare above thresholds).
How does this compare to California or New York?
California taxes wages 1%–13.3% progressively, plus 1.1% SDI. New York is 4%–10.9%, plus NYC's local tax for residents. Texas at $0 means meaningful savings — see the comparison tool above.
Does the take-home change if I contribute to a 401(k)?
Yes. Pre-tax 401(k) lowers your federal taxable income (saving roughly your marginal rate × contribution) but does not affect FICA. HSA contributions lower both. Use the calculator above with contributions filled in for personalized math.
