Can I Still Use My HSA From a Previous Employer?

Yes — you can still use an HSA from a previous employer, and nothing about leaving the job changes your access to the money. The balance is yours, every dollar of it, including any amount your former employer contributed. You can spend it on qualified medical expenses whenever you want, keep contributing if you enroll in a qualifying high-deductible plan, and move the account to a different custodian if you don’t like where it lives. What changes when you leave is administrative: payroll deductions stop, and the account is no longer tied to your former employer’s benefits system.

The Account Is Yours, Not Your Employer’s

Federal law defines an HSA as an individual trust or custodial account under Internal Revenue Code Section 223.¹ You hold the title. Your employer could facilitate payroll deductions and make contributions on your behalf while you worked there, but once the money landed in the account it belonged to you. No vesting schedule, no waiting period, no forfeiture clause. This is the sharpest line between an HSA and a Flexible Spending Account, where unused balances can vanish at year-end or when you leave.

The account survives every employment change. Quit, get laid off, retire, go freelance, take a year off, and the balance just sits there, continuing to grow tax-free through interest or investment earnings.² Your former employer has no mechanism to reclaim any portion of the funds.

Spending the Balance After You Leave

You can use HSA funds for qualified medical expenses whether or not you still work for the employer that set up the account. Qualifying expenses include doctor visits, prescriptions, dental work, vision care, mental health services, and medical equipment, among others.³ There is no deadline for spending. Unlike an FSA, HSA funds carry over indefinitely. You can pay for a procedure tomorrow or save the balance for healthcare costs in retirement.

You also do not need to be enrolled in any health plan to spend down an existing balance. Someone between jobs with no insurance can still swipe their HSA debit card at the pharmacy. The only requirement is that the expense itself qualifies.

Premiums You Can Pay During a Job Gap

HSA money generally cannot cover health insurance premiums, but four exceptions matter, and two of them are directly relevant when you leave a job:²

COBRA continuation coverage after leaving your job.
Health insurance premiums paid while you are collecting unemployment compensation.
Long-term care insurance, up to age-based limits set by the IRS each year.
Medicare Parts A, B, C, and D premiums after age 65. Medigap premiums do not qualify.

COBRA is the big one for people between jobs. Those premiums can be steep because you pay the full cost your employer used to subsidize, and being able to tap your HSA for that makes the gap far less painful.

Keep Records of Every Withdrawal

The IRS does not require you to submit receipts when you take a distribution, but you are expected to keep records proving each withdrawal paid for a qualified medical expense.⁴ If you get audited and cannot substantiate a distribution, it gets reclassified as taxable income, plus a 20% penalty if you are under 65. Hang onto medical bills, pharmacy receipts, and explanation-of-benefits statements. There is no time limit on when you can reimburse yourself for a past expense, so some people pay out of pocket now and reimburse themselves years later, letting the balance grow tax-free in the meantime. That strategy only works if you still have the receipt when you eventually take the distribution.

Can You Keep Contributing After You Leave?

Spending existing HSA money requires nothing more than a qualified expense. Contributing new money is where the rules tighten. To make deposits for 2026, you must meet all of the following on the first day of a given month:

Coverage under a High Deductible Health Plan with a minimum annual deductible of at least $1,700 for self-only coverage or $3,400 for family coverage. The plan’s out-of-pocket maximum cannot exceed $8,500 (self-only) or $17,000 (family).⁵
No disqualifying coverage. You cannot be enrolled in Medicare, Medicaid, a general-purpose FSA, or a spouse’s non-HDHP that covers you.
You are not claimed as a tax dependent by anyone else.

The HDHP does not have to come from an employer. If you buy an HDHP on the individual market during a gap between jobs, you remain eligible to contribute. If your next employer offers only a traditional plan, contributions have to stop, but your existing balance is unaffected.

For 2026, annual contribution limits are $4,400 for self-only HDHP coverage and $8,750 for family coverage.⁵ If you are 55 or older, you can add another $1,000 as a catch-up contribution. These limits include both your personal contributions and anything an employer puts in. They are not separate buckets.

Mid-Year Changes Prorate Your Limit

If you switch from an HDHP to a traditional plan (or vice versa) partway through the year, your contribution limit is prorated. Take the annual limit, divide by 12, and multiply by the number of months you were eligible. Eligibility is determined on the first day of each month, so if you had HDHP coverage on June 1 but switched to a traditional plan effective July 1, June counts and July does not.²

Watch for Double Contributions

A common problem when you change employers: both HR departments end up making payroll deductions in the same year, and together they push you past the annual limit. The IRS charges a 6% excise tax on the excess for every year it stays in the account.² You can avoid the tax entirely by withdrawing the excess, plus any earnings on it, before your tax filing deadline including extensions. The withdrawn earnings count as taxable income for the year you pull them out. Miss that deadline and the 6% keeps accruing each year until you either remove the excess or absorb it into a future year’s limit.

Moving Your HSA to a Different Custodian

When you leave, your HSA might be parked at a custodian you didn’t pick, sometimes with fees or investment options you don’t love. You are free to move it. There are two ways, and they work very differently.

Trustee-to-Trustee Transfer

The cleaner option. You ask your new HSA custodian to pull the funds directly from the old one. The money never touches your hands, so there is no tax reporting on the movement and no risk of accidentally triggering a taxable event. You can do unlimited trustee-to-trustee transfers with no once-per-year restriction. Fill out a transfer form with the new custodian, who coordinates with the old one. Expect two to six weeks.

60-Day Rollover

With a rollover, the old custodian sends you a check or deposits the money into your personal bank account, and you have 60 days to get it into the new HSA. Miss that window and the entire amount becomes a taxable distribution, potentially with a 20% penalty on top. The IRS limits you to one rollover in any 12-month period, so a rollover in March blocks another until the following March.⁶ Trustee-to-trustee transfers do not count against this limit.¹ For almost everyone, the transfer is the better choice.

Fees Before You Move

Most custodians charge a closing or transfer-out fee, often deducted from your balance before the money moves. These are typically modest, somewhere in the $20 to $50 range. Check your custodian’s fee schedule before initiating anything so the deduction doesn’t surprise you. Some custodians also charge monthly maintenance fees that quietly erode a small balance, which is another reason to consolidate an orphaned HSA into a provider you have chosen deliberately.

You Still Have to File Form 8889

Even if you did nothing unusual with the account during the year, you still have a filing obligation. Anyone who had an HSA at any point during the tax year must file Form 8889 with their federal return.⁷ The form reports contributions, calculates your deduction, and accounts for any distributions.

Your custodian sends two documents to help. Form 1099-SA reports all distributions made from the account during the previous year, and Form 5498-SA reports total contributions.⁸ The 5498-SA may arrive as late as May because you can make prior-year contributions up until the April tax deadline.

At Age 65, the Rules Loosen

If you are leaving a job on the way to retirement, one shift is worth flagging. Once you turn 65, the 20% penalty for non-medical withdrawals disappears.² You still owe ordinary income tax on any amount not used for qualified medical expenses, which makes the account function like a traditional IRA for non-medical spending. The tax-free benefit for medical expenses remains fully intact. Note that enrolling in Medicare disqualifies you from making new contributions, but has no effect on your ability to spend down the existing balance.

A Note on State Taxes

Most states follow the federal treatment. California and New Jersey are the notable exceptions. Both tax HSA contributions as regular income and tax the interest and investment earnings inside the account. If you live or work in either state, your W-2 will reflect higher state taxable wages than federal taxable wages by the amount of your HSA contributions, and you will need to report the account’s earnings on your state return. Residents of every other state generally receive the same triple tax benefit at the state level that they get federally.
