What Is Severance Pay?

Severance pay is compensation an employer voluntarily provides to an employee whose position is being eliminated, most often due to a layoff, reduction in force, or company restructuring. It is distinct from final wages or accrued vacation payouts, which many states legally require. Employers are not obligated under federal law to offer severance, yet many do as a matter of policy, goodwill, or contractual obligation. According to the Bureau of Labor Statistics, roughly 46 percent of private-sector workers in the United States have access to employer-provided severance benefits, with higher rates at larger companies and more senior roles. Severance is most commonly offered in layoff situations — employees terminated for cause, such as misconduct, are frequently excluded from eligibility. Employers typically require the departing employee to sign a release of legal claims against the company as a condition of receiving payment. This is a legal waiver and should be reviewed carefully before signing. Severance pay is separate from unemployment insurance, which is a state-administered programme funded by employer payroll taxes and governed by its own eligibility rules.

How Severance Pay Works in the United States

The Fair Labor Standards Act does not require employers to pay severance. However, when a company has a written policy in an employee handbook or an individual employment contract that promises severance, that promise is generally legally binding. Surveys estimate that approximately 60 percent of US companies maintain formal severance policies. The Worker Adjustment and Retraining Notification Act, known as the WARN Act, requires employers with 100 or more employees to provide 60 calendar days of written advance notice before a mass layoff affecting 50 or more workers at a single site. The WARN Act mandates notice, not severance pay — but failure to comply can expose the employer to liability of up to 60 days of back pay and benefits. Several states have enacted additional protections with lower thresholds: California, New York, New Jersey, and Illinois each have mini-WARN statutes that apply to smaller employers. For employees aged 40 and older, the Older Workers Benefit Protection Act, enacted under the Age Discrimination in Employment Act, requires employers to allow at least 21 days to review a severance agreement before signing and 7 days to revoke the signature after signing. In a group layoff affecting multiple employees, the review period extends to 45 days.

How to Calculate Your Severance Pay

The most widely used formula is: years of service multiplied by the weeks-per-year rate, then multiplied by weekly base salary. Standard policies offer one or two weeks per year of service. An employee earning $1,000 per week who has worked six years receives $6,000 under a one-week-per-year policy or $12,000 under a two-week-per-year policy. An employee earning $1,500 per week with ten years of service receives $15,000 under a one-week policy or $30,000 under a two-week policy. Many employers cap total severance weeks at 26, regardless of tenure. Some use a tiered structure: one week per year for the first five years, then two weeks per year for each additional year, rewarding longer-tenured employees proportionally. Executive-level packages are typically negotiated individually and can include three to twelve months of base salary, continuation of bonuses, accelerated vesting of stock options or restricted stock units, and extended outplacement support. The calculation uses base salary only and excludes bonuses, commissions, and overtime unless the policy explicitly states otherwise. To confirm the exact terms that apply to you, review your employment contract, offer letter, and employee handbook. If no written policy exists, the severance amount is entirely at the employer's discretion.

Tax Treatment of Severance Pay

The Internal Revenue Service classifies severance pay as ordinary income, treated identically to regular wages. It is subject to federal income tax at your marginal rate, applicable state income tax, Social Security tax at 6.2 percent on earnings up to the annual wage base, and Medicare tax at 1.45 percent, with an additional 0.9 percent surtax on individual earnings above $200,000. Employers can withhold federal income tax on severance using one of two methods. Under the flat supplemental-rate method, the employer withholds 22 percent if the severance is paid separately from regular wages and total supplemental wages paid to that employee during the year do not exceed $1 million — amounts above $1 million are withheld at 37 percent. Under the aggregate method, the employer combines the severance with the most recent regular paycheck and withholds at the rate applicable to the combined total, which can push withholding into a higher bracket. Either method may result in over- or under-withholding; any difference is reconciled when you file your annual federal income tax return. The United States does not have an equivalent to the United Kingdom's £30,000 tax-free redundancy allowance — all severance payments are fully taxable from the first dollar.

Negotiating a Better Severance Package

Severance packages are more negotiable than many employees realise, particularly for mid-level and senior staff with strong tenure and performance records. The most effective approach is to request an increase in base weeks first, then address add-ons once the core figure is agreed. Items commonly up for negotiation include a COBRA health insurance subsidy to offset the full premium cost for a defined period, outplacement services such as career coaching and resume support, modification or elimination of non-compete clauses, accelerated vesting of unvested stock options or RSUs, a written reference letter agreement, and payment structure. The payment structure matters: salary continuation paid weekly may delay unemployment benefit eligibility in some states, whereas a lump-sum payment typically does not affect it. For any package exceeding $10,000, or any agreement that includes a release of age discrimination claims under the ADEA, having an employment attorney review the document before signing is advisable. Submit your counter-offer in writing, referencing your years of service, documented performance results, and contributions that are difficult to replace. Use your full review period and, where applicable, your revocation window before committing.
