Understanding How an HSA Works and Its Limits

Health Savings Accounts (HSAs) are a valuable financial tool that can help individuals save for medical expenses while enjoying tax benefits. So, how does an HSA work and what are the limits?

An HSA works by allowing individuals to contribute money to the account, which can then be used to pay for qualified medical expenses. Here's how it typically works:

  • Individuals open an HSA through a qualified institution.
  • They contribute money to the account, which is tax-deductible.
  • The funds in the HSA can be used to pay for a wide range of medical expenses, from doctor visits to prescription drugs.
  • Any unused funds roll over from year to year, unlike Flexible Spending Accounts (FSAs).
  • There are limits to how much individuals can contribute to an HSA each year, which are set by the IRS.

For 2021, the contribution limits are $3,600 for individuals and $7,200 for families. Individuals who are 55 or older can make an additional catch-up contribution of $1,000. These limits are subject to change each year based on inflation.

It's important to note that HSAs must be paired with a high-deductible health plan (HDHP) to be eligible. This type of healthcare plan typically has lower premiums but higher deductibles.

By understanding how an HSA works and its limits, individuals can make informed decisions about saving for their healthcare expenses and taking advantage of the tax benefits it offers.


Health Savings Accounts (HSAs) are more than just a savings tool; they're an integral part of your financial strategy that promotes smart healthcare spending. With tax advantages and the ability to roll over unused funds year after year, HSAs can take the stress out of unexpected medical bills.
