Every employee in the United States pays FICA taxes, which fund Social Security and Medicare:
How much state tax do I pay in Texas if I make $100k a year?
If you make $100,000 in Texas, you pay $0.00 in state income tax because Texas has no personal income tax on earned wages. After taking the $15,000 federal standard deduction, your federal income tax is roughly $13,600 and your FICA taxes are $7,650 (6.2% Social Security and 1.45% Medicare). Your total tax burden is approximately $21,250 (effective tax rate of 21.25%), giving you an estimated net annual take-home pay of $78,750.
What is the standard deduction in Texas for the 2025/2026 tax year?
Because Texas does not levy a personal state income tax on earned wages, there is no state-level standard deduction or state personal exemption. However, you can claim the full federal standard deduction on your federal return ($15,000 for single filers, $30,000 for married filing jointly, and $22,500 for head of household).
Does Texas have local city income taxes or county wage withholdings?
Texas does not assess county or municipal personal income taxes. State income tax is uniform statewide, with no separate city withholding required outside of standard federal and state taxes.
How does my Texas tax liability change if I file as Married Filing Jointly?
In Texas, neither single nor married filers pay state income tax on earned wages. However, on your federal tax return, filing jointly doubles your standard deduction to $30,000 and broadens tax bracket thresholds, significantly lowering federal tax liability if one spouse earns more than the other.
Can I claim the Child Tax Credit (CTC) to lower my 2025 tax bill in Texas?
Yes. At the federal level, you can claim up to $2,000 per qualifying child under 17, with phaseouts beginning at $200,000 for single parents ($400,000 married). Texas residents benefit fully from the federal Child Tax Credit directly on Form 1040.
How do 401(k), Traditional IRA, and HSA contributions reduce my taxable income in Texas?
Contributing to a pre-tax traditional 401(k) (up to $23,500 in 2025) and Traditional IRA reduces both your federal and Texas state taxable wages. HSA contributions reduce your taxable income for both federal and Texas state income taxes.
What is the difference between my marginal tax rate and effective tax rate in Texas?
Your marginal tax rate is the statutory percentage assessed only on your highest tier of taxable income (your top federal and state bracket). Your effective tax rate is your total combined tax paid divided by your total gross income. Because of standard deductions and lower introductory brackets, your effective rate in Texas is substantially lower than your top marginal rate.
What happens if I live in Texas but work remotely for an out-of-state employer?
Generally, your wages are subject to income tax in Texas because you physically perform the work within the state. If your out-of-state employer withholds taxes for their home state, you will file a non-resident return with that state and a resident return in Texas, claiming a resident tax credit to prevent double taxation on the same income.
Does Texas tax retirement pensions, Social Security benefits, or 401(k) distributions?
No. Texas has zero state income tax on all forms of income, meaning Social Security benefits, 401(k) withdrawals, Traditional IRA distributions, and private pensions are 100% state tax-free.
