When Can I Enroll in an HSA? Tips for Understanding Health Savings Accounts

Enrolling in a Health Savings Account (HSA) can be a great way to save for medical expenses while enjoying tax benefits. If you're wondering when you can enroll in an HSA, here's what you need to know.

Generally, you can enroll in an HSA if you have a high-deductible health plan (HDHP). This type of health insurance plan typically has a higher deductible but lower premiums compared to other plans. To enroll in an HSA, you must:

  • Be covered by an HDHP on the first day of the month
  • Not be covered by other health insurance that is not an HDHP
  • Not be enrolled in Medicare

Additionally, you cannot be claimed as a dependent on someone else's tax return if you want to contribute to an HSA. It's important to consider these factors before enrolling in an HSA to ensure you are eligible.

Enrollment in an HSA typically occurs during your employer's open enrollment period. This is when you can choose your health insurance plan for the upcoming year, including opting for an HDHP and enrolling in an HSA. If you're self-employed or your employer does not offer an HSA, you can still open one through a financial institution that offers HSA services.

Keep in mind that the annual contribution limits for an HSA are set by the IRS and can change each year. For 2021, the contribution limit for individuals is $3,600 and $7,200 for families. These contributions are tax-deductible and can be used to pay for qualified medical expenses tax-free.


Understanding the importance of a Health Savings Account (HSA) is crucial for managing your healthcare expenses. You can enroll in an HSA if you hold a high-deductible health plan (HDHP), which is characterized by lower premiums paired with higher deductibles. To be eligible, make sure you:

  • Are enrolled in an HDHP as of the first day of the month
  • Don't have other non-HDHP health insurance
  • Are not currently on Medicare

Also, you can't be a dependent under someone else’s tax return to contribute to an HSA. The enrollment process usually aligns with your employer's open enrollment period, where you can select your health insurance plan, including the HDHP option. If you do not have an employer-sponsored HSA, consider opening one at a bank or credit union that supports HSAs. Remember, annual contribution limits apply, which for 2021 were $3,600 for individuals and $7,200 for families, and these contributions provide valuable tax deductions as well as the ability to withdraw tax-free for eligible medical expenses.
