When you’re new to Health Savings Accounts (HSAs), it’s easy to get excited by all the tax benefits. However, before adding money into your account, it’s important to understand the basic rules, including annual contribution limits. This guide covers HSA rules and explains what to do if you overcontribute to your HSA.
What is an HSA?
An HSA allows you to set aside money tax-free* to pay for eligible medical expenses for yourself, your spouse, and your tax dependents. HSAs offer several tax advantages:
Tax-free contributions
Tax-free growth
Tax-free distributions for eligible medical expenses
HSA Eligibility Requirements and Contribution Limits
To contribute to an HSA, you must be covered by a qualified high-deductible health plan (HDHP).
To qualify as an HSA-compatible HDHP, your qualified HDHP must meet the minimum deductible and maximum out-of-pocket requirements, which are indexed annually.
You (and your spouse if you have family coverage) cannot be covered by disqualifying health coverage, including but not limited to Medicare, a general-purpose Healthcare Flexible Spending Account (HCFSA), a non-qualifying HDHP, or Tricare. There are also some instances where receiving benefits from Indian Health Services will make you ineligible to contribute to an HSA. Your qualified HDHP must be active for each month you make contributions.
Once you’re eligible, you can contribute up to the allowed maximum amount for that tax year.
If you’re 55 or older, you can also make a catch-up contribution each year until retirement. You may also consider making an Individual Retirement Account (IRA) to HSA rollover. This rollover is allowed only once in your lifetime, and you must be enrolled in a qualified HDHP to make the transfer. Keep in mind that the amount you transfer counts toward your HSA contribution limit for that year.

Penalties for Excess Contributions
While it may be unintentional, contributing more than allowed can result in penalties. If you contribute more than the yearly limit:
The excess contributions are not tax-deductible
Employer contributions above the limit become taxable income and are reported on your Form W-2
There may be a 6% excise tax if excess contributions and any earnings are not distributed and properly taxed within the same tax year
What To Do if You Overcontribute to Your HSA
You have some options when you're in a situation where you may have overcontributed to your HSA. The timing of the contributions, interest earned, amount invested, and other factors can affect your next steps. Your options may include:
Withdrawing the excess contributions
Moving the excess contributions to the next year
Paying taxes on the excess contributions and earnings
It is important to gather all the details about your contributions and discuss the best method for your specific situation with your tax professional or legal advisor.
Be Proactive with Your HSA
Whether you’re actively contributing to your HSA or just taking advantage of employer contributions, it's your responsibility to monitor your account and the contributions. To avoid excess contribution penalties, start by knowing the annual limits, which may change from year to year. If you’re making monthly HSA contributions, you can divide your yearly limit by twelve payments to see the maximum you may be able to contribute per month. Eligibility is determined monthly, so you should monitor not only the amount you're contributing but also whether you're still eligible to contribute to a particular month.
Keep an eye on your HSA balance to help you stay within your annual contribution limit and meet your savings goals. Many HSA providers make this easy through mobile apps or online dashboards. And remember that you can only contribute while you are eligible, meaning you’re covered by a qualified HDHP and meet IRS requirements. If your coverage changes, you’ll need to stop contributing and be sure to notify your employer if they are contributing to your account or if you are handling your contributions through your employer via salary deductions. Remember, even if you stop making contributions, you can still use your existing funds for eligible expenses.
Additionally, HSAs are portable. You can take your HSA with you when you leave your job, and there is no deadline to spend the money. With so much flexibility, some HSA owners invest the money and plan to use the funds for healthcare expenses in retirement.
With a little planning and attention, you can enjoy all the advantages your HSA has to offer — and worry less about excess contributions. As always, please consult a licensed tax professional for appropriate advice given your individual situation.
