How Severance Pay Works in the US

Unlike the UK, the United States has no federal law requiring employers to pay severance when they lay off workers. The Fair Labor Standards Act (FLSA) simply does not mandate it. What you receive — if anything — depends on your employer's policy, your employment contract, or a negotiated agreement.

That said, severance has become standard practice at most mid-to-large employers because it serves their interests too: it reduces the risk of wrongful termination lawsuits and helps maintain employer brand reputation during layoffs. According to SHRM data, around 60% of US companies have a formal severance policy.

The major exception to the "no federal requirement" rule is the WARN Act (Worker Adjustment and Retraining Notification Act). If a company with 100+ employees lays off 50 or more workers at a single site, or 500+ across multiple sites, they must give 60 days' advance written notice. If they fail to do so, they owe employees up to 60 days' back pay and benefits — which functions like mandated severance. Some states (California, New York, Illinois, New Jersey) have "mini-WARN" laws with lower thresholds.

State law also matters: some states prohibit requiring employees to waive certain claims in exchange for severance, or mandate longer review periods for signing releases. If you are over 40, federal law (the ADEA/Older Workers Benefit Protection Act) gives you 21 days to consider a severance agreement and 7 days to revoke it after signing.

Severance Pay Calculation Methods

When employers do offer severance, there are three common approaches — and understanding them helps you evaluate whether an offer is fair.

Formula-based (most common for staff employees)
The standard formula is 1–2 weeks of base salary per year of completed service. A mid-level employee with 10 years at $1,500 per week receiving 2 weeks per year would get $30,000. Some companies cap this at 26 weeks total regardless of tenure.

Lump sum
Some employers offer a fixed lump sum unrelated to tenure — often 4, 8, or 12 weeks of pay. This is more common in smaller companies without formal HR policies. The advantage for the employee is simplicity; the risk is that it undervalues long service.

Salary continuation
Instead of a lump sum, the employer continues paying your regular salary on normal paydays for the severance period. This keeps you on health benefits longer (the coverage often ends with salary continuation) and can be useful tax planning if it straddles a calendar year.

Executive packages
C-suite and VP-level executives typically negotiate severance separately, often in employment contracts. Packages of 6–12 months of base salary plus target bonus are common. "Double-trigger" provisions (change of control + termination) are standard for equity-heavy packages.

Rule of thumb: if your employer's initial offer is below 1 week per year, it is on the low end and likely negotiable. If it is at or above 2 weeks per year, you are in typical-to-generous territory for staff roles.

Tax Treatment of Severance

Severance pay is taxed as ordinary income in the United States — there is no exclusion equivalent to the UK's £30,000 rule. Federal income tax, state income tax (where applicable), Social Security (6.2% up to the annual wage base), and Medicare (1.45%) all apply.

How your employer withholds matters. Two common approaches:

- Aggregate method: Your severance is added to your most recent regular paycheck and withheld at the rate applicable to that combined amount. Because this inflates your apparent pay rate, it often results in over-withholding. You will likely get a refund when you file your return.
- Flat percentage method ("supplemental wage" method): The IRS allows employers to withhold at a flat 22% federal rate (37% above $1 million) on supplemental wages. This is often more accurate but varies by your actual bracket.

Timing can matter significantly if your severance is large. Receiving a lump sum in a year where you have lower income (because you were only employed part of the year) can keep you in a lower bracket. If you can negotiate salary continuation instead of a lump sum, you may spread the income across two tax years.

Also consider: if you receive severance while unemployed, state unemployment benefits may be reduced or delayed during the period covered by severance, depending on your state's rules.

Negotiating Your Severance Package

Most severance offers are negotiable — employers expect some pushback, especially from longer-tenured employees. The key is to approach it as a professional discussion, not a confrontation.

Items to negotiate beyond the base amount:
- COBRA continuation: Employer-subsidised health insurance continuation (typically only 18 months under COBRA, but expensive at full cost). Ask them to cover premiums for 3–6 months.
- Outplacement services: Career coaching, resume review, and recruiter access. Employers often have existing vendor contracts; this costs them little extra.
- Non-compete scope and duration: If you are signing a non-compete, push to narrow the geographic area, shorten the duration, and limit the industry definition. An overly broad non-compete limits your earning potential.
- Reference letter: Request a specific, signed letter (not just "verify employment") that you can control the content of.
- Stock vesting acceleration: If you have unvested equity, ask for acceleration of the next tranche — especially if you are close to a cliff.
- Payment timing: Sometimes deferring into a new tax year reduces your effective rate.

Always request at least a week to review any severance agreement. If the package exceeds $10,000 or includes a non-compete, have an employment attorney review it before signing — the $200–$500 fee is almost always worth it.
