Texas Bonus Tax Calculator 2026
Texas has no personal income tax — its constitution bars one — so a Texas bonus check is reduced only by federal income tax, Social Security and Medicare.

Barred by the Texas Constitution
Article 8, Section 24-a of the Texas Constitution, titled "Individual Income Tax Prohibited," says "the legislature may not impose a tax on the net incomes of individuals, including an individual's share of partnership and unincorporated association income." Texas employers therefore withhold no state income tax from wages or bonuses.
Flat or aggregate is the decision that matters
Because there is no state line, a Texas bonus check turns almost entirely on the federal method. A $5,000 bonus nets $3,517.50 at the 22% flat rate and $3,451.19 if payroll adds it to a $3,000 biweekly paycheck. At $50,000 the gap is larger: $35,175.00 flat versus $28,808.45 aggregated. Either way the bonus is ordinary income on the federal return, where the real tax is settled.
When the work is in another state
Texans who work in Louisiana, Oklahoma or New Mexico are taxed there on wages earned there. On the same bonus that means an estimated $150.00 for Louisiana (flat 3% rate), $225.00 under Oklahoma's formula and $295.00 under New Mexico's 5.9% flat option.
