Laid Off With a December 31 End Date: What to Do Before the Year Ends

The notice says your last day is December 31. That gives you about eight weeks of paychecks, a calendar full of holidays, and a long list of things you suddenly need to figure out. It's a strange spot to be in: you still have a job, but you also don't.

You're not alone in it. Comcast just told Pennsylvania regulators it's laying off 634 employees at its Philadelphia headquarters, with the layoffs set to begin taking effect December 31, and it notified regulators of 119 more cuts in New Jersey, 159 in Washington state, and 82 in California (The Philadelphia Inquirer). Microsoft employees who accept its voluntary exit offer will also leave on December 31 (CNBC).

The good news: a year-end exit date gives you something most laid-off workers don't get, which is time. Here's how to use the weeks between now and December 31 so you walk into January with a plan, a budget, and health coverage that doesn't lapse.

Questions Answered

What should you check first in your layoff notice?
How much will your severance be after taxes, and how long will it last?
Does it matter if severance is paid in December or January?
What happens to your health insurance on January 1?
What should you do about PTO, your 401(k), and your FSA?
When should you file for unemployment?

Why You Got a Notice Weeks Ahead

If you work for a large employer, the advance notice usually isn't a courtesy. The federal WARN Act generally requires employers with 100 or more employees to give affected workers at least 60 calendar days' notice before a plant closing or mass layoff (U.S. Department of Labor). That's one reason a notice filed in late October can carry a December 31 date.

Those weeks are yours to use. Keep doing good work, but start working on your own plan now, not on January 2.

Step 1: Read Your Notice (and Get the Details in Writing)

Before you do any math, pull out your notice or separation letter and find these answers. If something isn't there, ask HR and ask for the answer in writing.

Your exact last day and whether you're expected to work through it or are on paid leave until then
Your severance formula: how many weeks, and whether it's a lump sum or paid out over time
When severance is paid: with your last paycheck, in December, or after you sign a release in January
When your health coverage ends: December 31, or the end of January
How unused PTO, your bonus, and any unvested stock are handled
How long you have to review the release. If you're 40 or older and part of a group layoff, federal law gives you at least 45 days to consider the agreement and 7 days to change your mind after you sign (EEOC).

Don't sign anything on the spot. You have time, so use it.

Step 2: Run Your Severance Numbers

Your severance is probably the biggest number on that letter, and it's also the one that's easiest to misread. Severance is wages: it's included in your income and subject to income tax withholding, Social Security, and Medicare (IRS Publication 525). Employers can withhold federal income tax on it at a flat 22% supplemental rate (IRS Publication 15).

So the number that hits your bank account is smaller than the number in the letter. Our free severance calculator does that math for you. Here's its default example:

Example: $80,000 salary, 10 weeks of severance	Amount
Weekly pay ($80,000 ÷ 52)	$1,538
Gross severance (10 weeks)	$15,385
Estimated withholding (22% federal, 6.2% Social Security, 1.45% Medicare)	$4,562
Estimated take-home	$10,823

That's about 30% less than the headline number, before any state tax. Withholding isn't your final tax bill, so you could owe more or get some back when you file, but the take-home figure is the one to plan around.

The calculator also handles the extras that often come with a year-end exit. Turn on unused PTO, a prorated bonus, or months of employer-paid COBRA under "More options," and it adds them to the package. Your numbers stay in your browser, and there's nothing to sign up for.

Step 3: Find Out How Long the Money Lasts

Knowing your take-home is half the picture. The other half is your runway: how many months your severance, savings, and any unemployment benefits can cover your bills.

Click Add runway in the calculator and enter your monthly spending and savings. In the same example, with $12,000 in savings, $4,000 a month in spending, and a December 31 separation date, the money lasts about 5.7 months, until around June 2027 (see this example).

Turn on unemployment and add, say, $500 a week for 26 weeks, and the same runway stretches to about 9 months, into September 2027 (see this example). Your state's actual benefit could be higher or lower, so swap in your own number once you know it.

If your runway comes out shorter than your field's typical job search, that's not a reason to panic. It's a reason to trim spending in November instead of in April, and to start applying now.

Step 4: Ask Whether Severance Lands in December or January

With a December 31 end date, timing matters more than usual. Individuals generally pay tax on income in the year they actually or constructively receive it (IRS Publication 538). A severance check paid on December 31 counts toward 2026. The same check paid on January 15 counts toward 2027.

Why that can matter:

Your tax bracket. If you'll earn less in 2027 because you're between jobs for part of the year, severance paid in January may be taxed at a lower rate when you file. If you expect to land a new role quickly, it may make little difference.
Social Security withholding. The 6.2% Social Security tax only applies to wages up to $184,500 in 2026, and the cap rises to $192,300 for wages paid in 2027 (Social Security Administration). If you've already earned past the 2026 cap this year, a December payment may skip that 6.2%, while a January payment starts the count over.
Marketplace health insurance savings. Savings on Marketplace plans are based on your estimated income for the year you need coverage (HealthCare.gov). Severance paid in January counts toward your 2027 income.

You often won't get to choose when severance is paid, but it's worth asking HR so you can plan. For big packages, a quick consult with a tax pro is money well spent.

Step 5: Lock In Health Coverage for January 1

This is the step with the hardest deadlines, so put it on your calendar this week.

Open Enrollment is happening right now. The HealthCare.gov Marketplace opened for 2027 coverage on November 1. Enroll by December 15 for coverage that starts January 1, and Open Enrollment ends January 15 (HealthCare.gov). Losing job-based coverage also qualifies you for a Special Enrollment Period if you lost coverage in the past 60 days or expect to lose it in the next 60 days (HealthCare.gov).

COBRA is the other option. It lets you keep your employer's group health plan for a limited time, but you may have to pay the full premium, up to 102% of the plan's cost (U.S. Department of Labor). You have at least 60 days to decide whether to elect it, counted from the later of the date you get the election notice or the date your coverage would end (U.S. Department of Labor).

A simple way to decide:

Get your COBRA premium quote from HR or the plan administrator.
Price a Marketplace plan for 2027 using your estimated 2027 income.
Plug the cheaper monthly premium into the calculator's COBRA premium field (and any months your employer covers) to see how health insurance changes your runway.

One more year-end detail: if you've already met this year's deductible, it may make sense to schedule any appointments, refills, or procedures before your coverage ends. Check your plan's dates first.

Step 6: Sort Out PTO, Your 401(k), and Your FSA

Unused PTO. Whether your employer has to pay out unused vacation depends on your state's law and your company's policy. Check your handbook, then your state labor office (U.S. Department of Labor state labor office directory). If your PTO won't be paid out, use it before December 31. If it will be, add the days in the calculator so you see what they're worth.

Your 401(k). Look for a vesting date or a year-end employer match you'd miss by leaving on December 31, and ask HR how contributions from your final paychecks and any severance are handled. You usually don't need to roll your account over right away.

Your FSA. If you have a health or dependent care FSA, ask how much is left and what the deadline is for using it once your employment ends. Rules vary by plan, and money left behind can be lost.

Step 7: Plan to File for Unemployment Right After Your Last Day

You generally can't collect unemployment while you're still employed and getting paid, so plan to file as soon as you're eligible after December 31. Bookmark your state's unemployment site now so you aren't hunting for it during the holidays. CareerOneStop's unemployment benefits finder links to every state's office.

Two things to check ahead of time:

Severance can affect benefits. In some states, it can delay or reduce unemployment depending on how and when it's paid. Check your state's rules before you count on benefits in your budget.
Gather your paperwork: your notice, your last pay stub, your employer's address, and your dates of employment.

Our guide on how to claim unemployment benefits walks through the application step by step.

Step 8: Use the Overlap to Job Hunt (Including Internally)

Eight weeks of overlap is a real advantage. You can apply while you still have a current title, a paycheck, and coworkers who'll vouch for you.

Look inside first. Layoffs and hiring often happen at the same time. Comcast, for example, plans to hire for more than 1,100 new positions as part of its restructuring, including more than 500 in Philadelphia, according to its notice (The Philadelphia Inquirer). Ask HR or your manager whether laid-off employees can apply internally.
Refresh your resume now, while your wins and numbers are fresh. Our quick resume writing wins can help.
Line up references before people scatter for the holidays.
Ask about outplacement. Many packages include career transition support. Here's what outplacement is and how to use it.
Don't write off December. Hiring slows around the holidays, but it doesn't stop, and a message sent in mid-December is one less thing to do in January.

When your last day comes, our first 7 days after a layoff plan picks up from there.

Your Year-End Layoff Timeline

When	What to do
This week	Read your notice, get open questions answered in writing, and run your numbers in the severance calculator
By late November	Get a COBRA quote, price a 2027 Marketplace plan, and check your PTO, 401(k), and FSA rules
By December 15	Enroll in a Marketplace plan if you want coverage that starts January 1
Before December 31	Use any PTO that won't be paid out, schedule care if you've met your deductible, and line up references
After your last day	File for unemployment and start your first-week plan
By January 15	Last day of Marketplace Open Enrollment for 2027 coverage

Just a note: this is general career guidance, not legal, tax, or financial advice. For big-dollar decisions, a quick consult with an employment attorney, a tax pro, or a financial planner can be well worth it.
