California vs Arizona severance tax in 2026

When comparing a layoff package in California and Arizona, the gross weeks offer is only half the story. This page holds the package formula fixed ($100,000 salary · 5 years · 2 weeks/year · single · lump sum) and runs both states through the same single-filer lump-sum engine so the only moving piece is state tax law.

California keeps about $78 more after modeled federal, state, and employee payroll tax. Most of that gap is state income tax ($481 in Arizona vs $403 in California).

Use the package ladder for smaller or larger offers, then open each state calculator page to change filing status, installments, or PTO add-ons.

What “tax on severance” means here

US severance is generally treated as wages for federal income tax and FICA. States with a wage income tax usually tax the package too; no-wage-tax states still show federal and payroll withholding.

For California the vignette shows $2,187 total withheld ($1,784 federal/payroll stack + $403 state) and $17,044 net. For Arizona: $2,265 total / $16,966 net.

This is an annualized single-filer model on the lump sum as if it were the year’s only wage income for bracket purposes — payroll systems may withhold differently mid-year. Reconcile on the return.

Paycheck tax vs unemployment offsets

California is listed as “No UI offset” and Arizona as “Verify with agency” for how severance interacts with unemployment insurance on our state pages.

A no-offset state can still withhold more income tax than a full-offset state. Tax and UI are separate decisions — lump sum vs installments often matter more for UI timing than for total income tax owed.

File for unemployment promptly and confirm current rules with each state agency; categories here are summaries, not claims advice.

What this comparison leaves out

Employer taxes, city wage taxes, negotiated extras (outplacement, COBRA subsidies), and equity acceleration are outside the vignette.

Installments that cross calendar years can change Social Security wage-base timing even when state tax looks similar.

Canada uses different rules (ESA / common law / retiring allowance) — use the Canada severance calculator for provinces.

Concepts to know for this comparison

Short definitions so package tax and UI rules do not get mixed up.

Gross package vs net

Gross is weeks × weekly pay (plus any modeled add-ons). Net here is gross minus modeled federal income tax, employee payroll, and state tax — about $17,044 in California vs $16,966 in Arizona on the vignette.

Why federal still appears

Even in no-wage-tax states, federal income tax and FICA apply to severance. That is why both sides show substantial total withholding.

UI offset category

Describes whether severance delays or reduces unemployment benefits week-for-week. It does not change the income-tax engine on this page.

Lump sum vs installments

Total tax owed depends on the tax year(s) the income lands in. Installments can stretch a UI blackout in full-offset states even when the tax total is similar.

Myths vs facts — California vs Arizona

“No state income tax means almost no tax on severance.”

California (No UI offset) vs Arizona (Verify with agency) can diverge on UI timing while the paycheck tax ranking goes the other way. Read both columns.

“Withholding on the check equals final tax.”

Employers may use supplemental methods. Your return uses annual income, filing status, and credits — this page is a standardized single-filer model.

“The $100k / 5-year gap is the same for every package.”

The modeled net gap moves from about $558 on the small package to $2,796 on the large one — match the ladder to your offer.

  4. 4Re-run with your filing status in the severance calculator.
  5. 5If either state is “Verify with agency,” call the unemployment office before relying on the offset label.
