How Does an HSA Work? Understanding the Basics of Health Savings Accounts

Health Savings Accounts (HSAs) are a valuable tool for managing healthcare expenses while saving for the future. An HSA works by allowing individuals to set aside pre-tax dollars in a special account to be used for qualified medical expenses. Here's how it works:

Key features of an HSA:

  • Contributions are made with pre-tax dollars, reducing your taxable income.
  • The funds in the HSA can be invested, allowing them to grow over time.
  • Withdrawals for qualified medical expenses are tax-free.
  • The account is portable, meaning it goes with you even if you change jobs or health plans.

Additional details on how an HSA works:

  • To be eligible for an HSA, you must be enrolled in a high-deductible health plan (HDHP).
  • Employers or individuals can contribute to the account up to annual limits set by the IRS.
  • Unused funds roll over from year to year, unlike Flexible Spending Accounts (FSAs).
  • HSAs can be used to pay for a wide range of medical expenses, including deductibles, copayments, prescriptions, and more.

By understanding the basics of how an HSA works, individuals can take advantage of the tax benefits and savings opportunities it offers.


Health Savings Accounts (HSAs) provide individuals with a smart way to manage healthcare expenses while also setting aside money for future needs. By allowing you to deposit pre-tax dollars into an HSA, you not only lower your taxable income, but also create a fund specifically for qualified medical expenses.

Some notable features of HSAs include:

  • Contributions can come from individuals or employers, enhancing your savings potential.
  • Investing your HSA funds can lead to significant growth over time, particularly if you don't tap into it right away.
  • Tax-free withdrawals for qualified medical costs mean that every dollar you save stretches that much further.
  • Your HSA is yours for life and is portable, easily moving with you even when you switch jobs.

To be eligible for an HSA, you must have a high-deductible health plan (HDHP), and contributions are subject to IRS limits each year. Additionally, unlike Flexible Spending Accounts (FSAs), any unused money rolls over annually, making HSAs a great long-term healthcare savings option.

HSAs can cover a multitude of medical expenses beyond just deductibles and copayments, including dental and vision care, offering you flexibility in how you use your account.
