More and more human resources and employee benefits professionals are calling Health Savings Accounts (HSAs) Medical 401(k)s. That’s because HSAs offer many 401(k)-like benefits, but also offer additional savings and flexibility not available with a 401(k).
5 Big HSA Advantages
1. Triple Tax Savings
An HSA offers triple tax advantages:
- Your contributions are tax deductible, reducing your taxable income.
- Funds grow tax-free.
- Withdrawals for qualified medical, dental, and vision care expenses are tax-free.
That’s a benefit no 401(k) can match. A 401(k) offers only tax-deferred growth. Your contributions are tax-free, but your withdrawals are taxed as ordinary income.
To qualify for an HSA, you must be enrolled in a High-Deductible Health Plan (HDHP). The minimum deductible is $1,700 for self-only coverage and $3,400 for family coverage. The maximum out-of-pocket (excluding premiums) is $8,500 for self-only coverage and $17,000 for family coverage. Maxing out your contributions effectively gives you a 25-30% discount on future health care costs.

2. Payroll/FICA Tax Savings
Your contributions via payroll deduction avoid the 7.65% Social Security and Medicare tax. Contributions to a 401(k) do not.
3. No Required Minimum Distribution
A 401(k) requires most participants to begin to take money out (and pay taxes on the distributions) starting at age 73 or 75, depending on your birth date.
Keep in mind, a 25% penalty could apply for funds not taken on schedule – annually by December 31.
An HSA has no required minimum distribution. You can let funds compound and grow tax-free throughout your lifetime. Even at age 75, you can leave money in place to continue to grow and compound. For long-term savers, that flexibility is powerful.
4. No “Use It or Lose It”
HSA funds are not forfeited at the end your plan or calendar year. You keep them and they roll over year after year. Even if you retire or move to another job, your HSA funds continue to be available to you. That makes HSAs especially attractive if you value ownership and long-term planning.
5. Retirement Flexibility
After age 65, you can withdraw HSA funds for non-medical expenses without a penalty. Only income tax applies, just like with a 401(k).
You can use funds to pay Medicare Part B, Part D, or Medicare Advantage premiums. That can’t be done with 401(k) funds unless taxes are paid on those funds first. This could save you thousands annually.

HSAs vs. 401(k)s
Having an HSA or a 401(k) is not an either/or situation. Both deliver outstanding benefits. Their appeal depends on your retirement goals and the health insurance options available to you.
