What is the severance tax rate in New Jersey for 2026?

Does New Jersey require employers to pay severance?

How does New Jersey treat severance for unemployment benefits?

Severance generally affects unemployment eligibility in two patterns: (1) Salary continuation: paid as weekly pay continuation typically delays UI eligibility week-for-week. (2) Lump-sum: treatment varies by state; in many states the lump sum is attributed to the week of separation rather than spread across the period it represents. Filing for UI immediately and letting the state agency determine the allocation is the standard approach; appeals are routine if the initial determination is wrong.
