When a company initiates a layoff or restructuring, employees often find their final paycheck includes a substantial severance package. While the check provides a crucial financial cushion during a period of transition, it often arrives with a significant surprise: a large tax bill. The reason severance pay taxed at a higher rate stems from how the Internal Revenue Service (IRS) classifies these payments, treating them not as a simple gift, but as a form of compensation that requires the highest withholding rates.
How the IRS Classifies Severance Payments
The primary factor determining the tax rate on severance is how the IRS categorizes the payment. Unlike a regular paycheck that covers salary for hours worked, severance is viewed as a substitute for wages and, in most cases, is considered supplemental wage income. Because of this classification, employers are required to withhold federal income taxes at a specific rate. For many years, the standard rule dictated that any supplemental wages, including severance, were subject to a flat 22% federal withholding rate if paid separately from regular wages.
The Shift to Flat Rate Withholding
Historically, the taxation of supplemental wages was complex, often requiring employers to aggregate the severance with the employee's regular salary for the pay period. This method frequently pushed the combined income into a higher tax bracket, resulting in a substantial and unexpected tax bill. To simplify the process and ensure consistent revenue collection, the IRS updated its withholding rules. The current flat rate system applies a uniform 22% rate to severance payments of $1 million or less, making the calculation straightforward for employers but often resulting in a higher immediate tax than some employees anticipate.
Why 22% Feels Higher Than Expected
While 22% might seem like a reasonable middle ground, it often feels like a "higher rate" compared to an employee's normal tax bracket. Most American taxpayers fall into the 10% or 12% ordinary income tax brackets, so seeing 22% withheld from a severance check creates a stark visual difference. Furthermore, this flat rate only covers federal income tax. The employer must still withhold the standard 6.2% for Social Security and 1.45% for Medicare, pushing the total combined withholding rate closer to 30% or more when all payroll taxes are factored in.
State Tax Implications
The financial impact becomes even more pronounced when state taxes are applied. Unlike federal rules which provide a flat rate, state tax treatment of severance varies significantly. Some states treat severance the same as federal law and apply a flat withholding rate, while others require employers to calculate the tax based on the employee's highest marginal tax bracket. In high-tax states like California or New York, this can result in state withholdings of 9% to 13%, effectively stacking the state tax burden on top of the federal 22%.
Strategies to Manage the Tax Impact
Employees receiving severance do have options to manage the immediate tax burden, though they require careful planning. One common strategy is to roll the severance into the final payroll alongside the last regular paycheck. While this can sometimes lower the supplemental rate, it risks bumping the total income into a higher bracket for that specific pay period. A more effective method is to request that the employer use the "aggregate method," where the severance is combined with the last regular paycheck, or to specifically instruct payroll to use a flat rate that aligns with the employee's actual tax bracket, if allowed by company policy.
The Lump Sum and Annual Tax Reconciliation
It is important to understand that the high withholding rate is an estimate, not the final tax bill. The 22% flat rate is simply the amount pulled from the check and sent to the government upfront. When the employee files their annual tax return, the severance income is added to their total taxable income for the year. If the total taxes paid throughout the year—including the withholding on the severance—exceed the actual tax liability, the employee will receive a refund for the difference. Conversely, if the withholding was insufficient, the employee will owe the remaining balance.
