Lump sum vs installment severance
A lump sum, salary continuation, or a mix, the choice changes your withholding, your cash-flow timing, and sometimes your unemployment. Here's how to weigh it.
Employers sometimes let you choose how severance is paid: one lump sum, continued salary over several months, or a split. The total is usually the same, but the shape matters. A lump sum gets you the cash now (useful for a runway cushion) but is withheld at the flat 22% supplemental rate. Salary continuation spreads the cash over time, is usually withheld through normal payroll (closer to your real rate), and can keep benefits like health coverage running. But it may offset unemployment for longer in some states.
Withholding: lump sum vs paid through payroll
$60,000 severance, single filer, $90,000 of other income, California:
| How it's paid | Federal withholding | Net check |
|---|---|---|
| Lump sum (flat 22%) | $13,200 | $38,250 |
| Through final payroll (aggregate) | $13,764 | $37,686 |
The lump sum withholds $13,200 at the flat 22%; run through payroll it withholds $13,764 at your marginal rate. Either way your actual tax is the same, the difference is just how much is prepaid and when you get the cash. The total tax reconciles at filing.

How to weigh it
- Choose the lump sum if you want the cash now for your runway cushion and are comfortable reconciling the withholding at filing.
- Choose salary continuation if keeping employer health coverage or steady cash flow matters more, and check whether it delays your unemployment in your state.
- A lump sum can spike one year's income, which matters for the ACA subsidy cliff, spreading it across two tax years can keep you under 400% FPL. See the COBRA vs marketplace calculator.
Questions
Is a lump sum taxed more than installments?
No, the total tax is the same. A lump sum is withheld more (flat 22%), but you reconcile at filing. Installments through payroll withhold closer to your real rate. More on the withholding myth.
Which is better for unemployment?
It depends on your state. Salary continuation can offset unemployment for the weeks it covers; a lump sum may be allocated to a shorter period. Check your state's rule before deciding.
