What Happens to Your HSA Money at the End of the Year

Yes, HSA funds roll over to the next year with no time limit

Money in a Health Savings Account does not disappear at the end of the calendar year. Unlike a Flexible Spending Account (FSA), which operates on a "use it or lose it" basis, an HSA carries your balance forward indefinitely. If you put $2,000 into your HSA in January and spend only $500 by December 31, the remaining $1,500 stays in your account and remains yours to use in future years.

This rollover feature is one of the core differences between an HSA and an FSA. Because HSA funds never expire, you can build a balance over time and use it strategically — either to cover medical costs now or to let it grow as a long-term savings vehicle for healthcare expenses later in life.

Key Takeaways

HSA funds roll over automatically each year with no expiration date, unlike FSA funds which are forfeited if unused.
You can accumulate HSA money across multiple years and use it whenever you need it for may have access to medical expenses.
If you change jobs or leave your employer, your HSA remains yours and you keep the full balance in your account.
Some HSA providers charge monthly maintenance fees that reduce your balance even if you do not withdraw funds.
After age 65, you can withdraw HSA funds for any reason without penalty, though non-medical withdrawals are taxed as income.

How the rollover works in practice

When your plan year ends (usually December 31 for most employers), your HSA custodian does not close your account or forfeit unused money. Instead, your balance simply carries into the next year. You continue to own that money and can use it to pay for may have access to medical expenses at any point — whether that is next month, next year, or ten years from now.

The only requirement is that you remain enrolled in an HSA-may be able to access high-deductible health plan (HDHP) to make new contributions. If you switch to a different type of health insurance, you stop being able to add new money to the HSA, but the money already in the account stays there and remains usable for may have access to medical expenses for life.

What happens if you change jobs or insurance

Your HSA is portable — it belongs to you, not your employer. If you leave your job, your HSA balance goes with you. You keep every dollar in the account regardless of whether you were there for one year or ten years.

If you switch to a new employer's health plan, you can continue using your existing HSA as long as the new plan is also an HDHP. Some people maintain the same HSA account; others open a new one with a different custodian. Either way, the money in your old account does not disappear. You can keep both accounts open, or you can roll the balance from one HSA to another (this is called an HSA-to-HSA transfer and does not count as a taxable event).

If you leave an HDHP and enroll in a different type of health insurance — such as a standard PPO or HMO — you can no longer make new contributions to the HSA. However, the balance you have already accumulated remains in the account and you can continue to use it for may have access to medical expenses indefinitely.

Account fees and how they affect your balance

While your HSA balance does not expire, some custodians charge monthly maintenance fees, annual fees, or per-transaction fees. These fees are deducted from your account balance whether or not you withdraw money. Over time, even small monthly fees can reduce what you have saved.

Before opening an HSA or choosing a custodian, ask about all fees: monthly maintenance charges, fees for debit card transactions, fees for paper statements, or fees for transferring money. Some custodians waive fees if you maintain a minimum balance (often $1,000 to $2,500). If your current HSA charges high fees, you can transfer your balance to a different custodian with lower costs — this is a free HSA-to-HSA transfer and does not affect your money.

Using your HSA as a long-term savings tool

Because HSA funds never expire and you can invest them (many custodians offer investment options similar to a 401(k)), some people treat the HSA as a retirement savings account. You can let the money grow tax-free for decades and withdraw it to pay for medical expenses whenever you need it.

This strategy works because may have access to medical expenses are not limited to current-year costs. You can pay for a medical bill from 2020 using HSA funds in 2025. You can also save receipts for past medical expenses and reimburse yourself from your HSA years later, as long as the expense was incurred after you opened the account.

After age 65, HSA rules change. You can withdraw money for any reason without the 20% penalty that applies to non-medical withdrawals before age 65. Withdrawals for non-medical reasons are taxed as ordinary income, but the penalty disappears. This makes the HSA function similarly to a traditional IRA at that point.

What counts as a may have access to medical expense

You can use HSA funds to pay for a wide range of healthcare costs: doctor visits, prescription medications, dental work, vision care, mental health treatment, and medical equipment. The IRS maintains a detailed list of may have access to expenses. If you are unsure whether a specific cost qualifies, check the IRS Publication 502 or ask your HSA custodian.

You cannot use HSA funds for health insurance premiums (with narrow exceptions for COBRA, Medicare, or long-term care insurance), cosmetic procedures, or over-the-counter medications without a prescription. If you withdraw money for a non-may have access to expense, you owe income tax on that amount plus a 20% penalty — unless you are over 65.

Keeping records for future withdrawals

Because you can use HSA funds years after you incur an expense, it is important to keep medical receipts and documentation. If you reimburse yourself from your HSA for a medical bill from three years ago, you should have proof that the expense was real and may have access to. The IRS does not require you to submit receipts when you withdraw money, but you must be able to produce them if audited.

Many people keep a folder of medical receipts separate from their HSA account. Others photograph receipts and store them digitally. The key is being able to match a withdrawal to a legitimate medical expense if needed.
