Does an HSA Expire? Rollover, Portability, and Age 65 Rules

No, an HSA does not expire. Money in a Health Savings Account rolls over automatically every year, stays in your name for life, and belongs to you regardless of job changes, retirement, or shifts in your insurance.¹ The balance itself has no deadline, but the rules around adding to it, spending it, and passing it on do change at certain points in your life.

The Balance Rolls Over Every Year

A Health Savings Account works differently from a Flexible Spending Account. An FSA generally follows a use-it-or-lose-it rule; an HSA does not. The IRS confirms that contributions stay in the account until you use them, and any amount left at year-end carries over on its own.¹ There is no government deadline to spend the funds.

Because prior-year balances never count against the next year’s contribution cap, the account can grow for decades. Interest and investment earnings inside the account accumulate tax-free.¹ Many account holders pay current medical bills out of pocket and leave the balance to compound.

The Account Follows You, Not Your Employer

The account is portable. If you change jobs or leave the workforce, the HSA goes with you, and a former employer cannot close it or reclaim deposited funds.¹ You keep full access for tax-free withdrawals on qualified medical expenses no matter where you work.

If you want to consolidate an old HSA into a new one, a trustee-to-trustee transfer moves the funds directly and is not taxed. You can also take the money personally and redeposit it into another HSA within 60 days, though that indirect method is limited to once every 12 months and must be reported on your return.¹

When You Can No Longer Contribute

The balance keeps rolling over, but the right to add new money depends on your health coverage. You can only contribute while enrolled in a qualifying high-deductible health plan. If your next job’s insurance is not an HDHP, you can still spend the existing balance tax-free on medical costs; you simply cannot put more in.

Medicare ends contributions entirely. Once you enroll in Medicare Part A or Part B, your HSA contribution limit drops to zero for that month and every month after, even if you are still working and covered by an HDHP.² The existing balance is untouched and stays available for tax-free medical spending.

One trap catches people who delay Medicare past 65. When you eventually enroll, Part A coverage is typically backdated up to six months (but no earlier than your 65th birthday), and the IRS treats any HSA contributions made during that retroactive period as excess contributions.¹ Signing up for Social Security after 65 triggers automatic Part A enrollment and the same lookback. Stop contributing at least six months before you plan to enroll to avoid a 6% penalty on the excess.

What Changes at Age 65

The balance itself does not change at 65, but two rules loosen. First, the list of qualified expenses expands to cover most health insurance premiums. Medicare Part B, Part D, and Medicare Advantage premiums qualify; Medigap (Medicare supplemental) premiums do not.² Long-term care insurance premiums and out-of-pocket costs for dental, vision, and other medical care remain qualified.³

Second, the 20% penalty on non-medical withdrawals disappears. Before 65, using HSA funds for anything other than qualified medical expenses triggers that 20% penalty on top of regular income tax.² After 65, non-medical withdrawals are still taxed as ordinary income, but the penalty is gone. The account then functions much like a traditional retirement account for non-medical spending.

What Happens to the Account When You Die

The closest an HSA comes to expiring is at the account holder’s death, and even then the outcome depends on who inherits it.

A Spouse Beneficiary

If your surviving spouse is the named beneficiary, the HSA becomes theirs. They step in as the account holder with the same tax advantages: tax-free withdrawals for medical expenses, continued investment growth, and the ability to make new contributions if they have qualifying HDHP coverage.²

Anyone Else

If a non-spouse inherits, the HSA loses its tax-advantaged status as of the date of death. The fair market value of the account becomes taxable income to the beneficiary in the year the account holder died.² The beneficiary can reduce that taxable amount by paying any of the deceased’s qualified medical expenses incurred before death, as long as the bills are paid within one year of the date of death.

No Beneficiary on File

Without a named beneficiary, the balance goes to the deceased’s estate and is included on the final tax return.⁴ Keeping the beneficiary designation current is what keeps the account out of probate.

Fees Can Chip Away at a Dormant Account

The rules do not shrink your balance, but fees can. Some HSA administrators charge monthly maintenance fees, paper statement fees, transfer fees, and account closure fees that may exceed the interest the account earns.⁵ If you have an old account from a former employer sitting with a modest balance, compare the fee schedule against what you earn. A trustee-to-trustee transfer to a lower-cost provider preserves the balance and triggers no tax.

Keep Your Receipts Longer Than You Think

Since there is no deadline to reimburse yourself, you can pay a medical bill today and pull the reimbursement out years later. That flexibility only works if you can prove the withdrawal matched a qualified expense. Every year you take a distribution, you report it on Form 8889.⁶

The IRS asks you to keep records supporting your return for the period of limitations, generally three years from the date you filed.⁷ If you plan to reimburse yourself for old expenses, hold those receipts indefinitely. The three-year clock starts from the return that reports the withdrawal, not the year you paid the bill.
