How Severance Pay Is Taxed
Severance pay is treated as ordinary wages — same as your salary. It's reported on Form W-2 (Box 1 wages) and subject to federal income tax, FICA (Social Security and Medicare), and state income tax. The character isn't different; it's just income, taxed at your marginal rate.
Withholding on severance: employers usually withhold federal tax at the supplemental wage rate of 22% (the standard for bonuses and other supplemental pay). For high earners in the 32-37% bracket, this severely under-withholds, creating a tax bill at filing.
Concrete example: $100K severance to a former $200K earner. Federal withholding at 22% = $22,000. Actual federal tax on the marginal $100K (at 32-35% rate stack) = approximately $33,000. The under-withholding gap is $11,000 — a surprise tax bill. State tax adds to this.
Strategic move: ask the employer to withhold at a higher rate (some allow), or make an estimated tax payment within 30-60 days of receiving the severance. The estimated payment fills the withholding gap and avoids underpayment penalty.
Multi-year severance: some severance packages spread payment over 6-24 months. This can be tactically valuable — receiving a portion in December and the rest in January splits income across two tax years, potentially keeping you in lower brackets in each year. If your employer is flexible, request payment timing that optimizes your tax situation.
The Unique Tax Opportunity of a Low-Income Year
Years of reduced income are tax-strategic windows. Even with severance, your total annual income may be lower than your normal salary. This creates opportunities for tax moves that wouldn't make sense in a peak-earning year.
Roth conversions: convert Traditional IRA assets to Roth at lower marginal rates. If your normal bracket is 32% but during a job-loss year you're in the 22% bracket, converting $50K saves $5,000 of federal tax (10 percentage points × $50K). Calculate exactly how much you can convert without spilling into higher brackets.
Capital gain harvesting in 0% LTCG bracket: if your taxable income drops below $48,350 single / $96,700 MFJ, long-term capital gains are taxed at 0%. Sell appreciated investments and immediately rebuy (no wash sale rule for gains) to step up basis without paying tax. Future sales will have higher basis and lower gains.
Tax-loss harvesting against severance income: if your investment portfolio has unrealized losses, harvest them. Excess losses (above $3,000 ordinary income offset) carry forward indefinitely, but using them in a high-bracket year (where the severance pushed you up) can be more valuable than using them later when your income normalizes.
Backdoor Roth IRA: if your income normally exceeds the Roth contribution limit ($165K single / $246K MFJ in 2026), but during a job-loss year drops below the threshold, you can make a direct Roth contribution. Skip the Backdoor Roth complexity entirely.
Unemployment Compensation Taxation
Unemployment benefits are taxable as ordinary income at the federal level. The state tax treatment varies: 13 states don't tax UI benefits, including California, New Jersey, Pennsylvania, and Virginia. Most states do tax them.
Unlike wages, UI benefits don't have FICA withheld. Federal withholding is optional (you have to request it via Form W-4V — 10% flat rate). Most UI recipients don't withhold, creating tax surprise at filing.
Maximum benefit varies by state. State maximum weekly benefits range from $235 (Mississippi) to $974 (Massachusetts). Most states cap UI duration at 26 weeks, though some states have shorter caps (12-20 weeks).
Strategic tax move: request the 10% federal withholding on UI benefits to avoid surprise tax bills. Set aside 5-15% additional for state tax if your state taxes UI. Since UI is typically much less than your previous salary, the absolute dollar withholding is small but prevents tax-time anxiety.
Special CARES Act provisions (2020-2021): excluded the first $10,200 of UI from federal tax for AGI under $150K. This was temporary and doesn't apply to 2026 UI. All UI benefits are now fully taxable federally.
ACA Health Insurance Subsidies
Losing employer health insurance creates urgent decisions. The most overlooked option: ACA marketplace insurance with premium tax credits (subsidies) based on income. For lower-income years, ACA subsidies can be substantial.
Subsidy calculation: based on Modified Adjusted Gross Income (MAGI) as a percentage of the Federal Poverty Level (FPL). The Inflation Reduction Act eliminated the income cliff at 400% FPL through 2025 (extended through 2026), so subsidies phase down gradually rather than disappearing at a threshold.
Concrete example: a single person with $50,000 of MAGI in 2026 ($30,000 income + $20,000 severance) qualifies for substantial premium tax credits — the second-cheapest Silver plan is capped at 4-6% of income, around $2,500-$3,000/year. Without subsidies, the same plan might cost $7,000-$10,000.
MAGI manipulation: deductible IRA contributions reduce MAGI (subject to income limits). HSA contributions reduce MAGI. Pre-tax 401(k) contributions reduce MAGI. Strategically reducing MAGI to fall into a higher subsidy bracket can save thousands in premiums.
Repayment risk: subsidies are estimated based on your projected income. If you underestimate (and earn more than projected), some or all of the subsidy must be repaid at tax time via Form 8962. Update Marketplace estimates whenever income changes significantly.
COBRA and Health Insurance Decisions
COBRA continuation: federal law allows you to keep your former employer's health insurance for up to 18 months (sometimes 36 months for special circumstances). You pay the full premium plus a 2% admin fee — typically $700-$2,000/month for individual coverage, $2,000-$4,000/month for family.
COBRA premiums are NOT deductible from federal taxes (unless self-employed and the COBRA premium is part of qualifying health insurance). For most employees, COBRA is just an expensive option — but it's the only way to maintain your existing doctors and prescriptions if you're mid-treatment.
ACA marketplace usually beats COBRA on cost for low-to-moderate income (with subsidies) but COBRA may be better for: those mid-treatment for serious conditions, those with deeply non-standard coverage that ACA Bronze/Silver can't replicate, or those with sufficient short-term liquidity to absorb the cost.
Self-employed health insurance deduction: if you become self-employed after job loss, your health insurance premiums (including COBRA, if you elect it) become deductible above-the-line. This is a meaningful benefit that can offset the cost of going freelance.
Short-term decision matrix: if you have 4+ months of expenses saved, ACA marketplace is usually right. If you're starting a new job within 60 days with health benefits, possibly skip insurance entirely (penalty-free since 2019) or use COBRA as a bridge. If you have serious medical needs in progress, COBRA's continuity is worth the cost.
Strategic Moves to Consider
Roll over your 401(k) carefully. You have several options: (1) leave it at the former employer's plan (usually fine, but limits future contribution access), (2) roll to your IRA (gives you investment flexibility but creates Backdoor Roth pro-rata complications later), (3) roll to your new employer's plan (if you have a new job and the plan accepts incoming rollovers — keeps the IRA pro-rata clean for Backdoor Roth).
Vested equity decisions. If your former employer had stock options or RSUs, check the post-termination exercise window (usually 90 days for ISOs to maintain qualifying treatment, sometimes longer). If you have NSOs, you'll owe ordinary income tax on exercise — coordinate with the rest of your tax situation.
Severance vs unemployment timing. Receiving severance prevents UI eligibility in some states or reduces benefits for others. Check your state's rules — sometimes structuring severance as 'salary continuation' has different UI implications than a lump sum.
State residency considerations. If you're considering relocating to a no-tax state, the year of unemployment can be ideal — your income is lower, simplifying the tax math, and you have flexibility to time the move around income recognition. Just be aware of trailing-tax sourcing rules on RSUs, options, and severance.
