What Is a Health Savings Account (HSA)?

by

A Health Savings Account (HSA) is a powerful financial tool that can help individuals save money for medical expenses while also offering significant tax advantages. Whether you’re dealing with high-deductible health plans (HDHPs) or simply looking to maximize your healthcare savings, understanding what an HSA is and how it works is essential for making the most of your healthcare budget.

In this article, we’ll explore everything you need to know about Health Savings Accounts, including how they work, the benefits they provide, eligibility requirements, and how to use them effectively for both short-term medical expenses and long-term savings.

What is a Health Savings Account (HSA)?

A Health Savings Account (HSA) is a tax-advantaged account designed to help individuals save money for medical expenses. It allows individuals covered by a high-deductible health plan (HDHP) to set aside pre-tax dollars to pay for qualified medical expenses, both for themselves and their dependents. The money deposited into an HSA is tax-deductible, grows tax-free, and can be withdrawn tax-free for eligible medical expenses.

Unlike traditional health insurance accounts, an HSA is owned by the individual, not the employer or insurance company. This gives you greater control over your healthcare funds and allows you to carry the account with you if you change jobs or health insurance plans.

How Does an HSA Work?

An HSA works by allowing you to deposit money into the account, where it can be used for eligible medical expenses. The main components of how an HSA works are as follows:

  1. Eligibility: To open an HSA, you must be enrolled in a high-deductible health plan (HDHP). These plans typically have higher deductibles and lower premiums compared to traditional health insurance plans. However, the HDHP must meet certain criteria set by the IRS to qualify for HSA enrollment.
  2. Contributions: You can contribute money to your HSA up to annual contribution limits established by the IRS. For 2025, the contribution limit is $3,850 for individuals and $7,750 for families. Those 55 or older can make an additional “catch-up” contribution of $1,000 per year.
  3. Tax Advantages:
    • Tax-deductible contributions: Contributions to your HSA are made with pre-tax dollars, reducing your taxable income for the year.
    • Tax-free growth: The money in your HSA grows tax-free, meaning you won’t pay taxes on any interest, dividends, or capital gains earned within the account.
    • Tax-free withdrawals: As long as the funds are used for qualified medical expenses, withdrawals are tax-free.
  4. Qualified Medical Expenses: The IRS defines a broad range of medical expenses that can be paid for with HSA funds. These include:
    • Doctor visits
    • Prescription medications
    • Dental care
    • Vision care
    • Certain medical procedures
    However, it’s important to keep receipts and records of your HSA expenditures to ensure they’re eligible. Non-qualified withdrawals are subject to taxes and a 20% penalty (10% if you’re 65 or older).
  5. Portability: An HSA is yours to keep even if you change jobs, health insurance plans, or retire. Unlike other health benefits, the funds in your HSA roll over from year to year and can accumulate indefinitely, growing into a savings tool for future medical expenses.
  6. Investment Opportunities: Once your HSA balance reaches a certain threshold, many providers allow you to invest your funds in stocks, bonds, and mutual funds, much like an individual retirement account (IRA). This can help your balance grow over time and turn your HSA into an additional retirement savings tool.

Eligibility for an HSA

Not everyone is eligible to open an HSA. To qualify, you must meet the following requirements:

  • Enrolled in a high-deductible health plan (HDHP): As mentioned earlier, your health insurance plan must be classified as an HDHP by the IRS. For 2025, an HDHP is defined as a plan with a minimum deductible of $1,500 for an individual and $3,000 for a family. The maximum out-of-pocket expense for 2025 is $7,500 for an individual and $15,000 for a family.
  • Not enrolled in other health coverage: You cannot be enrolled in other health plans that aren’t considered HDHPs, including other health insurance plans or Medicare.
  • Not claimed as a dependent on someone else’s tax return: If you are a dependent on someone else’s tax return, you are not eligible to contribute to an HSA.
  • Not enrolled in Medicare: Once you enroll in Medicare, you can no longer contribute to an HSA, although you can continue to use the funds in your account.

Benefits of an HSA

A Health Savings Account provides numerous advantages that can help you save money on healthcare costs and even plan for the future. Here are the key benefits of having an HSA:

1. Triple Tax Advantage

An HSA offers a rare triple tax benefit:

  • Tax-deductible contributions: Reduce your taxable income for the year.
  • Tax-free growth: Earnings on the account grow without being taxed.
  • Tax-free withdrawals: Withdrawals for qualified medical expenses are tax-free.

This makes an HSA one of the most powerful financial tools for healthcare savings.

2. Long-Term Savings Potential

Unlike other health-related accounts, such as flexible spending accounts (FSAs), HSAs do not require you to spend the funds within a year. Any money you don’t use rolls over year after year. This allows you to accumulate funds over time, creating a large nest egg to cover medical expenses in the future.

As the HSA balance grows, you can use the funds for healthcare in retirement, where healthcare expenses are likely to increase.

3. Flexible Use for Future Health Costs

One of the most significant advantages of an HSA is its flexibility. If you don’t need to use the funds for medical expenses now, you can let them grow for the future. In fact, once you reach the age of 65, you can use your HSA funds for non-medical expenses without facing the 20% penalty—although you will pay regular income taxes if you use it for non-medical expenses.

4. Lower Premiums, Higher Deductibles

With an HDHP, you typically pay lower monthly premiums. This means you can allocate more money to your HSA, where it will grow over time and be used when you need it most.

5. No “Use It or Lose It” Rule

Unlike Flexible Spending Accounts (FSAs), which require you to use the funds within a certain time frame or risk losing them, HSAs have no such restrictions. The money stays in your account and grows tax-free indefinitely.

How to Use Your HSA Effectively

To maximize the benefits of an HSA, here are some strategies for effective use:

  1. Contribute the Maximum: Try to contribute the maximum allowed by the IRS each year to take full advantage of tax deductions and grow your savings.
  2. Save for the Future: If you can afford it, avoid withdrawing money from your HSA for minor medical expenses and let your funds grow over time. This way, you build up a larger balance for retirement healthcare costs.
  3. Invest Your Funds: Once your balance reaches a certain threshold, consider investing your HSA funds in mutual funds or stocks to allow your savings to grow faster.
  4. Keep Track of Qualified Expenses: Make sure that the expenses you withdraw for are qualified by the IRS to avoid penalties. Keep receipts and maintain good records.

Conclusion

A Health Savings Account (HSA) is one of the best financial tools available for managing healthcare costs and planning for future medical expenses. By offering tax deductions, tax-free growth, and tax-free withdrawals for qualified medical expenses, an HSA provides an excellent opportunity for individuals to save on healthcare costs in both the short term and the long term. Whether you’re looking to reduce your current tax burden or prepare for healthcare expenses in retirement, an HSA can be a smart financial decision.
