A Health Savings Account, or HSA, is a type of savings account designed to help people pay for healthcare costs.

HSAs have been available since 2003 and are offered through many employers and financial institutions. According to the Employee Benefit Research Institute, approximately 32 million Americans had HSA coverage in 2023. These accounts are paired with high-deductible health plans, which are a specific type of health insurance. The combination can help people manage both their insurance costs and their out-of-pocket medical expenses.

This guide explains how contributions work, what you can use HSA funds for, tax considerations, and rules that govern these accounts. It also discusses how HSAs differ from other types of savings accounts like Flexible Spending Accounts (FSAs). Understanding these details can help you determine whether an HSA might fit your financial situation and healthcare needs.

The information in this guide is meant to be educational. HSA rules can be complex, and your specific situation may involve details not covered here. Many people find it helpful to review this information alongside conversations with their employer's benefits team, a tax professional, or their insurance provider to understand how these accounts work in their particular circumstances.

Practical Takeaway: Use this guide as a starting point to understand what an HSA is and how it functions. Keep in mind that HSA rules are set by federal law, and these rules can change. Checking current resources from the IRS or your financial institution can help you stay informed about any updates.

Understanding HSA Contribution Limits and Rules

HSA contribution limits change each year based on inflation adjustments set by the IRS. For 2024, individuals can contribute up to $4,150 per year to an HSA if they have individual coverage under a high-deductible health plan. For families, the limit is $8,300 per year. For 2025, these limits are expected to increase to $4,300 for individuals and $8,550 for families. These are the maximum amounts you can put into an HSA during a calendar year, whether the money comes from your paycheck, your employer, or you contribute it yourself.

There's an important exception called the "catch-up contribution." If you're age 55 or older, you can contribute an additional $1,000 per year beyond the standard limit. This allows older workers to build up more savings for healthcare expenses they may face in retirement. For example, a 58-year-old individual with individual HSA coverage could contribute $5,150 in 2024 ($4,150 plus the $1,000 catch-up amount).

Contributions can come from several sources. Your employer might contribute money directly to your HSA as part of your benefits package. You might also make contributions directly from your own money. If you receive contributions from multiple sources—say your employer contributes $1,500 and you contribute $1,000—the total must still stay within the annual limit. Any money contributed over the limit may be subject to taxes and penalties, so tracking contributions throughout the year matters.

Timing rules also apply to HSA contributions. Generally, you must contribute during the calendar year or by the tax filing deadline (typically April 15) to count the contribution for that tax year. There's a special rule called the "last-month rule" that allows people who establish an HSA in December to contribute the full year's amount, as long as they maintain HSA coverage for the following year. Understanding these timing windows can help you plan your contributions effectively.

Practical Takeaway: Track your HSA contributions from all sources to make sure you don't exceed the annual limit. Write down what your employer contributes and what you contribute yourself. Check the IRS website each year for updated contribution limits, as these amounts change annually.

How Money in Your HSA Grows and What You Can Use It For

One significant feature of an HSA is that unused money stays in the account from year to year. This is different from Flexible Spending Accounts, where you typically lose any money you don't use within a calendar year. If you contribute $3,000 to your HSA in 2024 and only spend $1,500 on medical expenses, the remaining $1,500 stays in your HSA and can be used in future years. This makes HSAs useful for long-term healthcare savings.

HSA accounts held at banks or financial institutions can earn interest, similar to a regular savings account. The interest rate varies depending on where your HSA is held and current economic conditions. Some people also invest HSA funds in stocks, bonds, or mutual funds through investment options offered by their HSA provider. When you invest HSA money, the potential for growth increases, but so does the risk. The money you've invested could go up or down in value depending on market conditions.

The list of qualified medical expenses that you can pay for with HSA funds is long. Common examples include health insurance premiums (in certain situations), doctor visit copays, prescription medications, dental work, vision care, hearing aids, and mental health services. According to the IRS, there are thousands of qualified expenses. HSA funds can also pay for over-the-counter items like pain relievers, allergy medication, and bandages if prescribed by a doctor. Physical therapy, laboratory tests, and medical equipment like wheelchairs or crutches are also covered.

However, some healthcare-related expenses are not covered. Cosmetic surgery, gym memberships, and general wellness products usually aren't covered. If you use HSA funds for non-qualified expenses before age 65, you pay taxes on the withdrawal plus a 20% penalty. After age 65, if you use HSA funds for non-qualified expenses, you pay the taxes but not the penalty—though this makes the account similar to a regular retirement savings account. Understanding what qualifies helps you avoid penalties and use your HSA funds wisely.

Practical Takeaway: Keep receipts for all medical expenses. Even if you pay for something with your regular bank account instead of your HSA card, you can reimburse yourself from your HSA later, as long as you have documentation. This flexibility lets you use your HSA strategically for long-term healthcare savings.

Tax Advantages and What They Mean for Your Finances

One major advantage of HSAs is their tax treatment. If your employer contributes money to your HSA, that money is not counted as taxable income to you. This means you don't pay federal income tax on your employer's contributions. For example, if your employer contributes $2,000 to your HSA and your salary would normally be $50,000, your taxable income is treated as $48,000 for tax purposes. This can result in real savings on your taxes, especially if you're in a higher tax bracket.

Money you contribute to your HSA yourself may also provide tax advantages, depending on how the contributions are made. If you contribute through a payroll deduction at work (before taxes are taken out), you avoid paying payroll taxes and income taxes on that money. If you contribute directly to your HSA outside of payroll, you can deduct those contributions on your tax return, reducing your taxable income. Either way, the money you put in isn't taxed when it goes into the account.

When you withdraw money from your HSA to pay for qualified medical expenses, those withdrawals are tax-free. This is different from a regular savings account, where the interest you earn is taxable, or a regular investment account where gains may be taxable. Over time, this can add up to meaningful tax savings. A person who contributes $3,000 per year for 20 years and uses the money only for qualified medical expenses avoids taxes on the full $60,000 contributed plus any interest or investment gains earned.

However, it's important to keep good records because the tax advantages only apply if you follow the rules. When you withdraw money, keep documentation showing that the expense was a qualified medical cost. The IRS can request this proof during a tax audit. Some people track their receipts in a folder or use apps designed to organize medical expense documentation. Many HSA providers also offer online tools to track your accounts and expenses.

It's worth noting that tax laws can change. What applies today may be different in future years. Tax situations are also unique to each person, so consulting with a tax professional about how an
