Severance Pay Tax: 6 Things to Settle Before You Sign

Severance Pay Tax: 6 Things to Settle Before You Sign

Severance pay tax catches people because the check looks smaller than the offer. A lump sum is generally treated as wages, so income tax, Social Security and Medicare taxes come out of it. The withholding is often a flat percentage unrelated to your actual bracket, so the real bill can arrive in April.

Here are six things to settle before you sign. It is a checklist, not a ranking. If you want a CPA's view of the package, Doug Johnson CPA is a Los Angeles firm that lists equity compensation among its specialties. Doug Johnson CPA is a paid featured member of Sam's List.

1. Treat Severance Pay Tax as Wage Tax, Not a Bonus

Severance is generally wages for tax purposes. Your employer withholds federal and, in most states, state income tax, and both of you owe Social Security and Medicare taxes. The Supreme Court held in United States v. Quality Stores (2014) that severance payments are generally subject to FICA. It appears on your W-2, not a 1099.

The limitation: this is the general rule, and a payment can be structured differently, for example as a settlement of a legal claim.

2. Check Severance Supplemental Withholding Against Your Real Bracket

Employers commonly withhold on severance at a flat supplemental rate, which has been 22% for supplemental wages up to $1 million in a year. Confirm the current figure with payroll. Above $1 million, a higher mandatory rate generally applies. An employer may instead combine severance with regular pay and withhold on the total.

Severance supplemental withholding is only a prepayment. Your actual tax is figured on your return, at your bracket. If your marginal rate is above the flat rate, you may owe more at filing; if below, you may get some back.

Illustrative $50,000 severance	Federal withheld at 22%	Tax at that marginal rate	Gap at filing
Taxed at 12%	$11,000	$6,000	$5,000 refund
Taxed at 24%	$11,000	$12,000	$1,000 owed
Taxed at 32%	$11,000	$16,000	$5,000 owed

The table is made up and federal only. It assumes the whole amount lands in one bracket and leaves out state and payroll taxes.

The limitation: a projection depends on your other income, filing status and any new job's pay, so treat it as a range.

3. Compare a Lump Sum With 409A Severance Installments

Timing can move income between tax years: a lump sum paid in December lands in this year, the same amount paid in January in the next. Installments spread income, which may keep more of it in a lower bracket.

Installments can also raise a Section 409A question. Section 409A governs many forms of deferred compensation, and severance paid on a schedule can fall under it. Many arrangements are structured to fit an exception, such as the short-term deferral or separation pay exception, but that depends on the exact wording. A violation can mean extra taxes and penalties.

The limitation: an exception can apply and still not suit you, and a delay can mean income you could have used. Have a professional read the plan language.

4. Find Out What Happens to Equity at Separation

Unvested restricted stock units are generally forfeited at separation unless the award agreement or severance terms say otherwise. Vested options usually have a limited exercise window. Incentive stock options generally must be exercised within three months of leaving to keep ISO treatment, and after that are commonly treated as nonstatutory.

The limitation: equity is often the most valuable and most plan-specific part of a package, and share value can fall before you sell.

5. Read the Rest of the Package: PTO, Health Coverage and Release Terms

Accrued PTO payout depends on your state and employer policy, and a payout is generally wages. Health coverage may continue under COBRA, usually at your own cost plus a small fee, so ask whether the company will pay premiums.

Then read the release and any non-compete or non-disparagement terms. Those are legal questions for an employment attorney. If you are 40 or older, federal law generally gives you at least 21 days to consider a release and 7 days to revoke it after signing.

The limitation: the offer deadline may be short. Ask for more time in writing, though an employer is not always obliged to grant it.

6. Ask Before You Sign: What a CPA and an Employment Attorney Each Answer

Two professionals answer two halves of the package. A CPA can model severance pay tax, check withholding and plan around the tax year and your equity. An employment attorney reads the release and negotiates terms. Bring the full offer letter and equity award documents; once you sign, many terms are fixed.

The limitation: advice costs money and the deadline may be close. Book the CPA call first, since the numbers shape what the attorney negotiates.

Frequently Asked Questions

Is severance pay taxed?

Yes, generally. Severance is commonly treated as wages, so federal income tax, Social Security and Medicare taxes apply, and most states tax it too. The amount withheld may not match what you owe, so project your actual tax.

How is severance supplemental withholding calculated?

Employers commonly withhold a flat supplemental rate, which has been 22% for supplemental wages up to $1 million; confirm the current figure. Some combine severance with regular pay instead. Withholding is a prepayment, and your return settles the real tax.

Are 409A severance installments a problem?

Not necessarily. Many severance plans fit a 409A exception, such as the short-term deferral or separation pay exceptions. Whether yours does depends on the wording, payment timing and any release. A failure can trigger extra tax on you, so ask a CPA or attorney to review before you sign.

Should I take a lump sum or installments?

It depends on your other income, the tax year and whether you need the cash now. A lump sum is simple but may push income into a higher bracket. Installments spread income but add 409A questions. Model both with a CPA.

If you want a CPA to look at your offer, you can browse accountants on Sam's List, including the firm above, and ask each whether it will review severance terms before your deadline.
