FAQ

How is severance taxed?
Severance is taxed as supplemental wages. The federal government withholds 22% on the first $1,000,000 of supplemental wages in a calendar year and 37% on amounts above that, plus FICA and any state withholding.
Is severance required by law?
No federal law requires private employers to pay severance, with limited exceptions. Some states (notably New Jersey for mass layoffs and Maine for plant closings) require statutory severance under specific conditions.
What is OWBPA?
The Older Workers Benefit Protection Act applies when an employee age 40 or older signs a severance agreement waiving age-discrimination claims. It requires at least 21 days to review (45 for group exits) and 7 days to revoke after signing.
Does WARN apply to my layoff?
Federal WARN applies to employers with 100 or more full-time employees when 50 or more employees at a single site of employment are affected, requiring 60 days advance notice or pay in lieu. Several states have lower thresholds and longer notice periods.
