Frequently asked questions

Usually no. Federal law generally does not require severance unless a contract, policy, collective bargaining agreement, or enforceable severance plan promises it. Some state wage-payment laws may require payment of promised severance once conditions are met.

The estimate multiplies weekly pay by years of service and applies a state-aware weeks-per-year baseline plus a cap. It is a screening model, not a legal entitlement model, because real plans often define eligibility, release terms, and payment schedules.

Lump-sum cash is only one part of value. A real package can include COBRA subsidy, bonus treatment, equity vesting, and outplacement. You should model total package value, not just base cash severance, before signing a release.

Yes, often. Employers commonly require a release of claims. For employees age 40+, the Older Workers Benefit Protection Act sets additional rules for waiver validity, including review and revocation periods in many cases.

Check the written severance policy, offer letter, and handbook first. If the plan is governed by ERISA, administrative claim and appeal rules may apply. In some cases, state wage-payment statutes can create penalties for nonpayment of promised amounts.

It depends on state rules and payment structure. Some states treat certain severance payments as disqualifying for specific weeks; others do not. Timing, allocation language, and whether payment is salary-continuation vs lump-sum can matter.

Yes, in most cases severance is taxable wage income and subject to withholding. Federal withholding, FICA, and possibly state/local taxes apply. The IRS generally treats severance as wages for payroll-tax purposes.

Document the policy terms, your eligibility facts, and payment history. Send a written demand and preserve correspondence. Depending on plan structure and jurisdiction, you may have ERISA remedies, contract claims, or wage-payment claims.
