Investing in Your HSA vs. Your 401(k) (2024)

Health Savings Accounts (HSAs) and 401(k) plans are offered by many employers in the United States. Both HSAs and 401(k) plans can offer tax benefits, but these two types of accounts have distinct purposes and rules. What is the difference between your HSA and your 401(k)?

How an HSA Works

An Health Savings Account (HSA) is a savings account paired with a high-deductible health plan (HDHP). In 2022, HDHPs have an annual deductible of $1,400 or more for individuals and $2,800 or more for families.The health plan also must have limits on out-of-pocket medical expenses. In 2022, out-of-pocket expenses cannot exceed $7,050 for individual coverage and $14,100 for family coverage. In 2023, HDHPs annual deductible increases to $1,500 or more for individuals and $3,000 or more for families.Also, out-of-pocket expenses limit increases to $7,500 for individual coverage and $15,000 for family coverage.

To make HSA contributions, you must have an HDHP. Additionally, you cannot have other health coverage or be enrolled in Medicare. You also cannot be claimed as a dependent on someone else’s tax return.

Typically, you cannot use your HSA to pay for premiums. The funds in the account can be used to pay for expenses like your deductible, co-payments, and co-insurance.

The money in the account accrues tax free, and you have the option of investing HSA funds to potentially increase your returns.

How a 401(k) Works

A 401(k) is a retirement savings plan that allows employees to contribute money, often through payroll deductions, to an investment account. Employers can elect to match all or some of employees’ 401(k) contributions. You typically have the option to choose from different investment types, often mutual funds, for your 401(k).

Traditional and Roth are the two main types of 401(k) plans, and tax treatment is the primary difference between these two options. With a traditional 401(k), you will wait to pay taxes until you withdraw money from the account, typically in your retirement years. With a Roth 401(k), you contribute money after taxes, which means that withdrawals in your retirement years will be tax free.

What Are the Contribution Limits?

Each year, the Internal Revenue Service (IRS) sets contribution limits for HSAs and 401(k)s. In 2022, individuals can contribute up to $3,650 to their HSAs. Individuals with family health coverage can contribute up to $7,300. For 2023, the contribution limits increase to $3,850 and $7,750 respectively.

Individuals who are age 55 or older can make an annual catch-up contribution, an additional $1,000. These limits include any contributions made by the individual and the employer.

If you make HSA contributions that exceed the limit set by the IRS, the excess amount will generally be subject to a 6% excise tax.

In 2022, the IRS set the maximum 401(k) contribution as $20,500 (rising to $22,500 in 2023). If you are 50 or older, you are also eligible to make an additional catch-up contribution of $6,500 (rising to $7,500 in 2023). In 2022, the IRS limits employer and employee contributions to $61,000 (rising to $66.000 in 2023).

If you over-contribute to your 401(k), the excess amount needs to be returned to you. That amount will be considered taxable earnings, and they are subject to a 10% early distribution tax if not withdrawn before annual tax filings are due.

What Are the Tax Benefits and Considerations?

HSAs are considered tax-advantaged accounts. Your contributions to an HSA are tax deductible, and any contributions that your employer makes are not included in your gross income. Additionally, the earnings from your HSA are not taxable, and the distributions that you use to pay for qualified medical expenses are also tax free. You are able to make tax-free withdrawals to pay for qualified medical expenses at any age.

While your HSA may be set up with the help of your employer, it is not tied to them. You are able to take the account and all of the funds in it with you if you change jobs or retire. You can continue to leverage the account during your retirement to pay for medical expenses in retirement. Once you turn age 65, you can begin using your HSA funds for non-qualified expenses without paying a tax penalty. Instead, you will simply pay income tax on the funds used for non-qualified expenses.

Tax deferral is one of the main benefits of a traditional 401(k). The money that you contribute is pretax, which means your taxable income is less for that year. You do not have to pay taxes on the money in your traditional 401(k) until you begin making withdrawals during your retirement years. 401(k)s, unlike HSAs, come with required minimum distributions (RMDs).

Money is contributed to a Roth 401(k) after income taxes, which means that you do not have any tax deductions during the years when you make contributions. When you make withdrawals during retirement, you will not have to pay any taxes.

Keep in mind that withdrawing money from your 401(k) before you reach the age of 59½ means that you will incur a 10% additional income tax. If you qualify for a hardship withdrawal, you can avoid the 10% penalty, but you will still owe taxes.

The Bottom Line

You can have both an HSA and a 401(k). You can leverage the former to help you cover medical expenses, while the latter will help you to save up for retirement. Typically, you can opt for a certain amount of each paycheck to go into your HSA and your 401(k). Your employer may also make contributions to both accounts, depending on your benefits package. You can use both your HSA and your 401(k) as retirement planning tools.
