What Is a Health Savings Account (HSA)?

Healthcare in the U.S. can be costly and complex, especially if you’re enrolled in a high-deductible health plan. That’s where a Health Savings Account (HSA) comes in—a powerful financial tool that helps you manage medical expenses and save money on taxes. But what is a Health Savings Account, really?

In this guide, we’ll explain everything you need to know about HSAs, including how they work, who qualifies, their benefits and limitations, and how to use them to your advantage.

What Is a Health Savings Account?

A Health Savings Account (HSA) is a tax-advantaged savings account designed for individuals enrolled in a high-deductible health plan (HDHP). It allows you to set aside money—pre-tax—to pay for qualified medical expenses.

The key benefits? Contributions are tax-deductible, the money grows tax-free, and withdrawals for eligible expenses are also tax-free. It’s a triple tax advantage that can help reduce your healthcare burden both now and in the future.

How Does an HSA Work?

An HSA functions much like a personal savings account but is specifically for medical costs. Here’s how it works:

• Open an Account: You can open an HSA through banks, credit unions, or HSA administrators if you’re enrolled in an HDHP.

• Make Contributions: Contributions can be made by you, your employer, or even a family member.

• Spend on Medical Expenses: Use your HSA funds to pay for doctor visits, prescriptions, dental, vision care, and more.

• Funds Rollover: Unused funds roll over each year, unlike Flexible Spending Accounts (FSAs).

• Investment Options: Many HSAs allow you to invest your balance once it reaches a certain amount.

Who Is Eligible for a Health Savings Account?

To open and contribute to an HSA in 2025, you must meet these criteria:

• Be covered under a high-deductible health plan (HDHP)

• Have no other non-HDHP coverage

• Not be enrolled in Medicare

• Not be claimed as a dependent on someone else’s tax return

What Qualifies as a High-Deductible Health Plan (HDHP)?

For 2025, the IRS defines HDHPs as follows:

• Minimum deductible: $1,650 for individuals / $3,300 for families

• Maximum out-of-pocket: $8,300 for individuals / $16,600 for families

These thresholds are adjusted annually to reflect inflation and healthcare costs.

2025 HSA Contribution Limits

The IRS sets annual contribution limits, and for 2025 they are:

• Individual coverage: $4,150

• Family coverage: $8,300

• Catch-up contribution (age 55 and older): Additional $1,000

You can contribute up until April 15, 2026, for the 2025 tax year.

The Triple Tax Advantage of an HSA

HSAs are unique because they offer three levels of tax savings:

1. Pre-Tax Contributions – Reduce your taxable income.

2. Tax-Free Growth – Investment earnings and interest grow without tax.

3. Tax-Free Withdrawals – As long as you use the funds for qualified medical expenses.

This makes HSAs one of the most tax-efficient savings tools available today.

What Can You Use an HSA For?

You can use HSA funds for a wide range of qualified medical expenses, including:

• Doctor visits and co-pays

• Prescription drugs

• Dental treatments

• Eye exams, glasses, and contact lenses

• Mental health therapy

• Chiropractic care

• Durable medical equipment

• Long-term care services

• Certain insurance premiums (e.g., COBRA or Medicare Part B after age 65)

For a full list, consult IRS Publication 502.

What Happens If You Misuse HSA Funds?

Using HSA money for non-qualified expenses before age 65 triggers:

• A 20% penalty

• Income tax on the withdrawn amount

After age 65, the 20% penalty is waived. You can withdraw funds for any reason, though non-medical uses will still be taxed as income.

Benefits of a Health Savings Account

1. Triple Tax Advantage

Few financial tools offer tax savings at every stage—contribution, growth, and withdrawal.

2. Rollover Feature

Unlike FSAs, you never lose unused HSA funds. They roll over year after year.

3. Investment Opportunities

Grow your savings by investing in mutual funds, ETFs, or stocks once you meet the provider’s minimum balance requirement.

4. Portability

Your HSA stays with you even if you change jobs, insurance plans, or retire.

5. Retirement Flexibility

After 65, you can use HSA funds for non-medical expenses without penalty—similar to a traditional IRA.

Drawbacks and Limitations

1. HDHP Requirement

You must have a high-deductible health plan to open or contribute to an HSA, which may not be ideal for everyone.

2. High Out-of-Pocket Costs

HDHPs come with high deductibles, which can be financially stressful for people with ongoing medical needs.

3. Risk with Investments

Investing HSA funds comes with market risk, including the possibility of losing money.

4. Penalties for Misuse

Incorrect use of HSA funds can lead to tax penalties and headaches if not properly documented.

How to Open an HSA

Opening an HSA is a straightforward process:

1. Choose a Provider: Banks, credit unions, and online platforms all offer HSAs.

2. Compare Features: Look at fees, interest rates, and investment options.

3. Submit Your Application: Provide ID and proof of HDHP enrollment.

4. Make Contributions: Fund your account via payroll deductions, transfers, or employer contributions.

Tips for Maximizing Your HSA

• Keep Receipts: Maintain detailed records in case you’re audited.

• Max Out Contributions: Take full advantage of the annual limits.

• Invest for the Future: Let your funds grow tax-free through investing.

• Use HSA Debit Cards: Pay for qualified expenses conveniently.

• Think Long-Term: Save your HSA for retirement healthcare costs.

HSA vs FSA vs HRA: What’s the Difference?

Understanding these differences is key to choosing the right account for your healthcare strategy.

Real-Life Example: How HSAs Pay Off

Example: Sarah, 30, opens an HSA and contributes $3,000 a year while enrolled in an HDHP. She invests her funds, and after 10 years, the account grows to $45,000. She uses $5,000 for a surgery and continues saving the rest. By retirement, she has a robust tax-free fund for medical costs—saving thousands compared to traditional savings.
