Severance Tax Rate in Texas 2026: No State Income Tax Doesn't Mean No Tax

Texas Has No State Income Tax, But Severance Is Still Federally Taxed

A laid-off Texas resident receiving severance from an Austin tech employer, a Houston energy firm, or a Dallas finance company sees a single state-level absence on the pay stub: no state income tax withholding. Texas is one of seven US states with no individual income tax, alongside Florida, Washington, Nevada, South Dakota, Tennessee, and Wyoming (plus Alaska and New Hampshire under specific rules).

The misconception that follows from “no state income tax” — that severance is therefore tax-free or near-tax-free in Texas — is wrong. Severance is treated as supplemental wages under IRS Publication 15-A, which imposes a flat 22% federal income tax withholding regardless of state. FICA — Social Security and Medicare taxes — also applies federally. The combined federal withholding plus FICA lands near 30% before any high-income Medicare surcharge for typical white-collar severance.

That’s substantially lower than New York’s combined ~46% or California’s combined ~38%, but it’s not zero.

This article walks through the actual math for Texas severance, the source-state issue that catches remote workers and recent movers, and the specific Texas Workforce Commission rules around severance and unemployment claims.

The Federal Layer Applied to Texas Severance

Severance pay is supplemental wages, which the IRS defines as wages other than regular wages — bonuses, commissions, overtime, accumulated sick leave, severance, prizes, and similar payments. Under federal law per IRS Publication 525 and the supplemental withholding rules in Publication 15-A, employers withhold federal income tax on supplemental wages using one of two methods:

• Flat rate method: 22% on supplemental wages up to $1 million in a calendar year, then 37% on the excess. Most Texas employers use this method for severance.
• Aggregate method: Calculate withholding as if the supplemental wage were added to the most recent regular wage payment. Less common for severance because of administrative complexity.

The 22% supplemental rate is mandatory for the portion above $1 million in a single calendar year — this isn’t a choice. The 22% on the portion under $1 million is the standard practice. For Texas residents with no state income tax to add, the math is straightforward: 22% federal income tax withholding plus FICA.

FICA breaks down as:

• Social Security: 6.2% on wages up to $176,100 for 2025 with annual COLA adjustment for 2026 per the Social Security Administration’s announcement. Cumulative across the year.
• Medicare: 1.45% on all wages, plus 0.9% surcharge on wages above $200,000 for single filers ($250,000 for joint filers). The 0.9% is withheld once an individual employee’s YTD wages cross $200,000 regardless of filing status.

For a Texas employee earning $120,000 base who receives 16 weeks of severance ($36,900), the math works out:

• Federal income tax withholding: 22% × $36,900 = $8,118
• Social Security (assuming prior wages didn’t exceed wage base): 6.2% × $36,900 = $2,288
• Medicare: 1.45% × $36,900 = $535
• Total federal withholding: $10,941 — roughly 29.6% of gross

The same severance for the same role in New York would have an additional 11.7% state + 4.25% NYC (if resident) — another roughly $5,900 deducted. In California, the additional state withholding plus SDI would add roughly $2,800. Texas’s no-state-income-tax structure produces net take-home roughly 16-30% higher than the New York or California equivalents on identical gross severance.

The Source-State Issue

The single biggest tax trap for Texas-residents on severance is the source-state rule. Most US states tax wages based on where the underlying services were performed, not where the recipient currently lives. Severance is compensation for past services, which means the state where those services were performed can sometimes claim tax on the severance even after the employee has moved.

Several common scenarios:

Recent move from California or New York to Texas before separation. If the severance compensates work performed in California or New York, the source state can claim tax on the proportionate share. A worker who spent 8 years in San Francisco, moved to Austin in March, and was laid off in October might still owe California tax on the portion of severance attributable to the 8 years of California service.

Remote work for a New York employer while resident in Texas. New York’s “convenience of the employer” rule treats remote work for a New York employer as New York-source for tax purposes unless the remote work is required for the employer’s necessity rather than the employee’s convenience. A Texas-resident remote employee of a New York firm has historically owed New York tax on the wages under this rule, which extends to severance.

Hybrid work across multiple states. Severance attributable to a multi-year tenure that spanned work in different states gets allocated based on the work-day distribution during the relevant period. Accurate records of work-day locations are valuable in defending the allocation if a source state audits.

The general approach: file a non-resident return in the source state claiming the allocated portion of severance, and pay state tax there. Texas’s lack of state income tax means there’s no offsetting credit to claim — the state tax paid to the source state is a real cost that wouldn’t apply if the underlying services had been performed in Texas the entire time.

Severance and Texas Unemployment

The Texas Workforce Commission treats severance pay as potentially deductible from unemployment benefits under specific conditions. The TWC’s unemployment guidance distinguishes between two categories:

Wages in lieu of notice. Severance paid for a specific period — for example, “8 weeks of pay” — is treated as wages in lieu of notice for that period and disqualifies the recipient from unemployment benefits during the period.

Lump-sum severance not tied to a period. Severance paid as a single lump sum without a specified period it represents is generally not deductible against unemployment, though TWC will investigate the underlying agreement to determine whether the lump sum is functionally equivalent to wages for a period.

The practical implication: how the separation agreement characterizes the severance payment materially affects unemployment timing in Texas. A lump-sum payment without a stated week-equivalent is more favorable for unemployment than the same dollar amount paid as 8 weeks of salary continuation.

This differs from New York’s approach to severance and unemployment — see the JPMorgan severance package discussion of how salary continuation interacts with unemployment in major bank separations. New York’s treatment is more uniformly week-for-week deductible regardless of how the payment is structured.

Filing for unemployment immediately after separation is the standard advice in Texas, even if severance is being paid. The TWC determines the allocation based on the documentation provided; appeals are routine if the initial determination is incorrect. A laid-off employee who delays filing while severance is paid generally loses no eligibility — but receives no benefits during the wait either, which means the delay is purely downside.

Reconciliation at Filing Time

The 22% federal supplemental withholding rate is not the final federal tax rate. Actual federal tax owed reconciles on Form 1040 against the year’s total income and standard brackets.

For typical white-collar Texas severance recipients earning under $200,000 in total annual wages, the 22% supplemental rate is slightly above the 22% marginal bracket for joint filers (which starts at $94,300 of taxable income for 2026) and below the 24% bracket. The reconciliation produces near-zero adjustment for most filers in this range — modest refund or modest balance, dominated by other factors like deduction profiles.

For high earners — Texas tech executives, Houston energy executives, Dallas finance executives — the 22% supplemental rate sits well below the actual marginal bracket. A Texas-resident MD or VP earning $400,000+ annually whose severance is withheld at 22% federal will owe additional federal tax at filing. The amount depends on the total income picture but typically lands in the 10-15% range of the gross severance.

The Social Security wage base reconciliation is straightforward and usually invisible to the employee. An employee whose total wages crossed the $170,300 wage base during the year stops accruing additional Social Security on subsequent wages including severance. An employee whose total wages stayed below the wage base owes Social Security on the entire severance.

What’s Worth Tracking Before Signing

For Texas residents, three questions are worth answering before signing a separation agreement:

1. Was any of the underlying work performed in a state with income tax? Source-state allocation can materially change the tax picture, particularly for employees who moved to Texas recently or worked remotely for an out-of-state employer.

2. How is the severance characterized in the agreement? “Wages in lieu of notice for X weeks” is functionally worse for Texas unemployment timing than “lump-sum severance” — both negotiable language at signing time.

3. Will the year’s total income exceed $1 million? The 37% federal supplemental rate on amounts above $1 million per calendar year is relevant for senior executives at major Texas employers. Payment-timing flexibility (splitting across two calendar years) sometimes produces material federal tax savings.

None of these change the formulaic severance amount itself, but they affect the after-tax take-home meaningfully. For Texas residents in finance or tech roles, the after-tax picture is generally favorable compared to coastal-state equivalents — the absence of state income tax is real money on a typical white-collar severance.
