Severance weeks stack with health accounts: FSA balances die at termination, HSA pays premiums tax-free, and monthly severance reads as wages in SGA and state offsets. The year-end audit is the family bill. The premium comparison is in the marketplace guide , the cash order in the 30-day plan , and the comp archive in the records guide .

Severance weeks stack with health accounts: FSA balances die at termination, HSA pays premiums tax-free, and monthly severance reads as wages in SGA and state offsets. The year-end audit is the family bill.

The Lines

  • FSA: spend-down before the last day; grace rules vary; balances end with employment (see the exit checklist).
  • HSA: qualified premiums (COBRA, ACA) come out tax-free; the triple advantage lives at irs.gov (see the COBRA accounts guide).
  • SGA & offsets: monthly severance as wages, state suspensions, and the SGA test (see the SGA guide and the structure guide).
  • Year-end: W-2 stacking, 1095-A reconciliation, and the January file (see the reconciliation guide and the new-year guide).

The premium comparison is in the marketplace guide, the cash order in the 30-day plan, and the comp archive in the records guide.

The FSA Countdown In Your Last Weeks

Direct answer: a health FSA balance is forfeited when you lose eligibility, and eligibility usually ends on your last day. Contributions are made pre-tax across the year, but the full elected amount is available early, so leaving mid-year means you keep the money you spent and lose the rest. Your two jobs are to spend down eligible items before the last day and to find out whether the plan continues under COBRA.

  • Get the plan year dates in writing. Ask for the plan year start, the run-out or grace period your plan offers, whether a carryover is allowed and in what amount, and whether separation is listed as a forfeiture event.
  • Confirm COBRA eligibility for the FSA. A health FSA can be a COBRA-qualified benefit. If it is, you may elect continuation and keep spending the balance you already funded; the election window is the same 60 days described in the COBRA entry, and the COBRA Election Notice generator documents it.
  • Do not raise your election in open enrollment if you are leaving. A higher election buys a bigger early-access pool, but the unspent part is lost on your last day. Take the enrollment snapshot before you change anything; see open enrollment.
  • Buy eligible items in the order they last. Prescriptions and 90-day supplies, vision and dental work, glasses and contacts, and durable medical equipment beat gift cards and speculative purchases. Keep every receipt with the date on it.
  • Ask about the post-separation claim route. Some administrators pay claims incurred before separation after the last day if they are submitted inside the run-out window. Get the deadline and the submission address in writing.

HSA as the premium payer

If your plan is a qualifying high-deductible health plan, an HSA does the work an FSA cannot. The account is yours, it survives separation, and the IRS treats qualified medical withdrawals as untaxed. That is why it is often the best source of money for the coverage you buy after you leave.

  • COBRA premiums and marketplace premiums are qualified expenses. Paying continuation coverage from an HSA keeps those months cheaper than after-tax cash. Compare the premium in the COBRA Cost Calculator before you elect.
  • Employer HSA contributions follow the account agreement. Money the employer promised is not automatically yours on separation. Read the vesting and forfeiture language, then put any unpaid contribution in the final settlement demand alongside wages.
  • Stop contributing when eligibility ends. Contributions require a qualifying plan, so the month your coverage ends is usually the month contributions stop. Prorate the year and correct an over-contribution promptly.
  • Keep the receipts for reimbursement later. Unspent HSA money rolls forward indefinitely, so you can pay now and reimburse yourself in a future year. That option is worth more than an FSA balance during a job search.

Severance Weeks, SGA, And The January Reconciliation

How severance is paid changes the records several agencies read. Monthly salary continuation looks like wages in the weeks it covers, which matters to a state workforce agency that treats continuation differently than a lump sum, and to a disability determination that looks at earnings against substantial gainful activity. Rules that were not re-verified in this build are shown as not verified on the site, so ask the agency rather than asserting a week count; see the SGA entry and the Washington unemployment page where allocation is the stated rule.

  1. Write down your coverage end date; the marketplace enrollment window starts on that date, per ACA special enrollment.
  2. In January, reconcile the forms against each other: the W-2 wage lines, the 1095-C months coverage was offered, and any 1095-A from the marketplace. The Form 1095-C entry explains the missing-month problem when two employers split the year.
  3. Report the FSA forfeiture and any employer HSA contribution to whoever prepares your return, so the pre-tax lines on the W-2 match reality.
  4. Keep one folder for the year: election confirmations, run-out notices, receipts, and both coverage forms.

Frequently Asked Questions

What happens to my FSA balance when I leave?
Unspent funds are normally forfeited when eligibility ends, because the balance is funded by contributions you made pre-tax. The plan document sets the run-out period, grace rule, and carryover, and some plans allow continuation under COBRA. Read it before you spend.
Can I keep using my FSA after my last day?
Sometimes. If the health FSA is a COBRA-qualified benefit, electing continuation can let you keep submitting claims for expenses incurred while covered. Ask the administrator for the eligibility end date and the claim submission deadline in writing before you sign anything.
Is an HSA better than an FSA if I am job searching?
Usually, yes. An HSA is portable, keeps unspent money across years, and can pay COBRA or marketplace premiums as a qualified expense. An FSA forfeits what you do not spend, so it suits a year with predictable, front-loaded medical costs.
Does monthly severance affect disability or unemployment records?
It can. Salary continuation looks like wages in the weeks it covers, which some agencies count and others ignore. Rules not re-verified in this build are shown as not verified, so ask your agency how installments are treated before you file or certify.

FSA forfeiture is a plan rule with a use-it-before-termination line, and the continuation window that keeps a post-separation claim route open is a state rule graded in this build. Confirm the forfeiture date with the plan administrator, confirm the continuation length with the state agency named on the state rule pages, and keep receipts after you leave with the record described in the HSA portability entry.
