Do HSA Funds Roll Over?
If you have a Health Savings Account, or HSA, you may worry about the same deadline that applies to a Flexible Spending Account. The good news is simple: an HSA has no year end deadline. The money does not vanish on December 31.
This guide explains what happens to HSA money at the end of the year, what happens if you change jobs or retire, and what changes when you stop being eligible to add new money. Every rule comes from IRS Publication 969.
The short answer
Yes. Money in a Health Savings Account, or HSA, rolls over from year to year. There is no use it or lose it deadline, and there is no limit on how much can roll over. The balance stays yours if you change jobs or retire, and it keeps growing until you use it for qualified medical expenses.
What is an HSA, in one minute
An HSA is a Health Savings Account. You can only open and use one if you have a high deductible health plan, known as an HDHP. Money goes into the account before tax, and you use it to pay for qualified medical expenses.
The account belongs to you, not to your employer. That fact is the key to everything in this guide. Because the account is yours, the money in it is yours, and it stays yours when your job or your health plan changes.
Yes, the money rolls over
IRS Publication 969 states the rule in plain words: ‘Amounts that remain at the end of the year are generally carried over to the next year.’ That is the whole answer. Unspent money does not expire, and it does not need to be used by a date.
The same publication says, ‘The contributions remain in your account until you use them.’ There is no cap on the rollover. Whether you have $100 left or $10,000 left, the full amount carries over to the next year.
Earnings on the money in the account are also protected. Publication 969 says, ‘Earnings on amounts in an HSA aren’t included in your income while held in the HSA.’ The balance can keep growing while it waits for a medical cost.
The money stays yours
Publication 969 calls an HSA portable, and it says, ‘An HSA is portable. It stays with you if you change employers or leave the work force.’ If you leave a job, the account goes with you. If you retire, the account stays yours.
You can also take money out at any time. Publication 969 says, ‘You are permitted to take a distribution from your HSA at any time; however, only those amounts used exclusively to pay for qualified medical expenses are tax free.’
That freedom is the big difference from an employer plan that ends when the job ends. An HSA is not tied to one employer or one year. It is a long term account that follows you.
What happens if you stop being eligible
To add new money to an HSA, you must be an eligible individual. Publication 969 says you must be covered under a high deductible health plan on the first day of the month, have no other health coverage except what the rules allow, not be enrolled in Medicare, and not be claimed as a dependent on someone else’s tax return.
If you stop meeting those tests, for example by moving to a health plan that is not a high deductible plan, or by enrolling in Medicare, you cannot add new money to the HSA. The account itself does not close, and the money in it does not go away.
You can still use the balance you already have to pay for qualified medical expenses. The rule that stops is the rule for adding money, not the rule for using money. That is why the balance keeps its value even after you lose eligibility.
How an HSA differs from an FSA
An FSA, or Flexible Spending Account, works the other way round. FSAs are generally use it or lose it plans. Money that is not used by the end of the plan year is normally lost, unless the plan offers a grace period or a carryover.
The grace period can be up to 2 and a half months after the end of the plan year. If the plan allows a carryover instead, the amount is capped. For 2025, Publication 969 says the maximum carryover amount is $660, and the FSA salary reduction limit for 2025 was $3,300.
An HSA has neither of those limits. There is no grace period to watch, because there is no deadline at all. There is no carryover cap, because the whole balance rolls over. Our FSA guide explains the FSA rules in full.
The 2026 limits
The IRS sets a limit each year on how much can be added to an HSA. For 2026, Publication 969 says you can contribute up to $4,400 if you have self only HDHP coverage, and up to $8,750 if you have family HDHP coverage.
That limit is about adding money, not about keeping money. It does not cap the rollover. If your balance is already above the yearly limit, that is fine, because the limit only applies to new contributions in that year.
Worked example: three years of rollover
Example only. This example uses simple round numbers to show how a balance rolls over year after year. It is not a real person, and it is not a promise.
Suppose you add $100 a month to your HSA. That is $100 times 12, which is $1,200 in a year. In year 1, you spend $300 on qualified medical costs. $1,200 minus $300 leaves $900, and that $900 rolls over to year 2.
In year 2, you add another $1,200. $900 plus $1,200 is $2,100. You spend $500. $2,100 minus $500 leaves $1,600, and that $1,600 rolls over to year 3.
In year 3, you add another $1,200. $1,600 plus $1,200 is $2,800. You spend nothing. The full $2,800 rolls over to year 4. No deadline forced you to spend it, and no cap cut it down.
Mistakes to avoid
- Treating an HSA like an FSA, and rushing to spend the balance before year end.
- Adding new money after you stop being eligible, for example after enrolling in Medicare.
- Using HSA money for a cost that is not a qualified medical expense, and paying tax on it.
- Leaving the account behind when you change jobs, and forgetting it exists.
- Not checking the yearly contribution limit before you add money.
The fix is simple: know the rules in Publication 969, and let the balance roll over.
Quick answers
Yes. Amounts that remain at the end of the year are generally carried over to the next year, with no deadline and no cap on the rollover.
No. An HSA is portable. It stays with you if you change employers or leave the work force, and the money in it stays yours.
No. You must be an eligible individual to add new money. But you can still use the balance you already have for qualified medical expenses.
