Here is the fact to hold onto if a layoff ever lands on your desk: severance pay is not required by federal law. The U.S. Department of Labor says it plainly. Severance is a matter of agreement between employer and employee, not a legal entitlement under the Fair Labor Standards Act.
That sounds like bad news, and sometimes it is. But it also means severance is a contract, and contracts have two sides. The company is offering money because it wants something from you, usually a signed release of legal claims, a quiet exit, or both. Anything a company wants is something you can negotiate over, and the tax treatment of what you accept is more predictable than most people think.
Where severance actually comes from
Since no statute mandates it, severance flows from one of three places: a written employment contract, a company severance plan or policy, or a one-off offer made at termination. If your employer maintains a formal severance plan, it may be governed by ERISA, the federal benefits law, which requires the plan to follow its own written terms and gives you a route to claim benefits you were promised. Ask HR whether a plan document exists and get a copy. If the offer on the table is worse than the plan says, that is your first negotiating point, and it is one backed by federal law rather than charm.
What is genuinely negotiable
More than the headline number. The weeks-of-pay figure gets the attention, and a common framework is a set number of weeks per year of service, but the surrounding terms often matter as much:
Health coverage is a big one. You will generally have the right to continue your group health plan through COBRA at your own cost, and the Labor Department’s COBRA guide for employees explains how continuation works. Employers can sweeten a package by paying some months of those premiums, and many will if asked. Beyond that, people successfully negotiate the timing of payments, payout of unused vacation where state law does not already require it, treatment of unvested bonuses or equity, outplacement services, an agreed neutral reference, and the wording of a non-disparagement or non-compete clause. If you were let go mid-year, a prorated bonus is a reasonable ask, not an outrageous one.
The waiver you are signing, and the clock you get
Nearly every severance agreement asks you to waive legal claims against the employer. For workers 40 and older, federal age discrimination law sets specific safeguards, which the Equal Employment Opportunity Commission’s guidance on severance waivers spells out: you must be given at least 21 days to consider the agreement (45 days in a group layoff, along with information about who was selected), at least 7 days to revoke after signing, and a written recommendation to consult a lawyer. A waiver also cannot strip rights that are not waivable, such as filing a charge with the EEOC or claiming unemployment benefits. Do not let anyone rush you past these windows; they exist precisely so the decision is made with a clear head.
How severance is taxed
Severance is wages in the eyes of the IRS. It is subject to federal income tax, Social Security, and Medicare taxes just like your regular paycheck, and it will appear on your W-2. The Supreme Court settled the payroll tax question in 2014, so there is no clever structure that makes severance FICA-free.
For withholding, severance is treated as supplemental wages. Under the rules in IRS Publication 15, an employer paying it separately from regular wages can withhold a flat 22 percent for federal income tax, or combine it with regular pay and withhold under the normal tables. That 22 percent is only withholding, not your actual tax rate. If a large lump sum lands in one year, it can push part of your income into a higher bracket, and if your real rate is lower, you will get the difference back at filing time. Some negotiators ask to split payments across two calendar years to smooth the tax hit; employers often agree because it costs them nothing.
Severance and unemployment benefits
Accepting severance does not automatically disqualify you from unemployment insurance, but states treat it differently. Some states reduce or delay weekly benefits during the period severance is allocated to; others disregard lump sums entirely. The only reliable answer comes from your state unemployment agency, so file your claim promptly anyway and report the severance accurately. Never sign an agreement that purports to bar you from filing for unemployment; benefits eligibility is decided by the state, not by contract.
Before you sign anything
Take the full review period. Read the release, the restrictive covenants, and the ERISA plan if one exists. Compare the offer to what colleagues in past layoffs received, ask in writing for the specific improvements that matter most to you, and consider an hour of an employment lawyer’s time for a large package; it routinely pays for itself. The company drafted the agreement to protect its interests. The review window is your chance to protect yours.
