Is an HSA Worth It for Young Adults?

A Health Savings Account (HSA) is a specialized savings account designed to help individuals save for healthcare expenses on a tax-advantaged basis. It is paired with a specific type of health insurance plan, allowing account holders to manage medical costs while building long-term savings. For young adults, an HSA offers advantages that extend beyond immediate healthcare needs, supporting both current and future financial well-being.

HSA Fundamentals and Eligibility

To be eligible to contribute to an HSA, an individual must be enrolled in a High Deductible Health Plan (HDHP). This type of health plan is characterized by a higher deductible than traditional insurance plans, which generally results in lower monthly premiums.

For the calendar year 2025, an HDHP must have a minimum annual deductible of $1,650 for self-only coverage or $3,300 for family coverage. Additionally, the annual out-of-pocket expenses, which include deductibles, co-payments, and co-insurance but not premiums, cannot exceed $8,300 for self-only coverage or $16,600 for family coverage. These thresholds are adjusted periodically by the Internal Revenue Service (IRS).

Beyond the HDHP requirement, an individual cannot be enrolled in Medicare, nor can they be claimed as a dependent on someone else’s tax return. If these conditions are met, an individual can open and contribute to an HSA for qualified medical expenses.

The Triple Tax Advantage

A primary appeal of Health Savings Accounts lies in their unique “triple tax advantage.” The first advantage is that contributions made to an HSA are tax-deductible. This means that the money contributed reduces an individual’s taxable income for the year, potentially lowering their overall tax liability.

The second advantage is that the funds within an HSA grow tax-free. Similar to retirement accounts, any interest, dividends, or capital gains earned on the investments held within the HSA are not subject to taxes while they remain in the account. This allows the money to compound more rapidly over time, increasing its growth potential.

The third and particularly beneficial aspect is that withdrawals from an HSA are tax-free when used for qualified medical expenses. This includes a wide range of costs such as doctor visits, prescription medications, dental care, vision care, and even certain over-the-counter medical supplies. Examples of qualified medical expenses also include acupuncture, chiropractic services, and long-term care insurance premiums up to certain limits.

Strategic Use for Young Adults

For young adults, an HSA can serve as more than just a savings vehicle for immediate healthcare costs; it can become a powerful long-term investment tool. Young adults often have relatively low current medical expenses, which allows them to contribute to their HSA with the goal of investing the funds rather than immediately spending them. This strategy leverages the tax-free growth component of the HSA over a long time horizon.

The funds in an HSA roll over from year to year, meaning they do not expire like funds in a Flexible Spending Account (FSA). This rollover feature enables sustained growth of the account balance, which can accumulate substantially over decades. By investing HSA funds, young adults can build a significant nest egg that can be used for future healthcare expenses, including those in retirement. After age 65, HSA funds can be withdrawn for any purpose without penalty, though withdrawals not used for qualified medical expenses will be subject to ordinary income tax. This transforms the HSA into a supplemental retirement account for healthcare, a significant and often unpredictable expense in later life.

Setting Up and Managing an HSA

Establishing and managing an HSA involves a few straightforward steps. HSAs can be opened through various financial institutions, including banks, credit unions, and investment firms, or often through an employer’s benefits program. It is advisable to compare providers based on fees, investment options, and ease of access to funds.

Contributions to an HSA can be made in several ways, such as pre-tax payroll deductions if offered by an employer, or direct contributions made after-tax which can then be deducted on an individual’s tax return. For 2025, the annual contribution limit for an individual with self-only HDHP coverage is $4,300, and for those with family HDHP coverage, it is $8,550. Individuals age 55 and older can contribute an additional $1,000 annually as a catch-up contribution.

Using HSA funds for qualified medical expenses is typically convenient; many providers issue a debit card linked directly to the account for immediate payment at the point of service. Alternatively, individuals can pay for expenses out-of-pocket and then reimburse themselves from their HSA, keeping detailed records for tax purposes.
