Is an HSA Subject to Social Security Tax? Explained

Health Savings Accounts (HSAs) have gained popularity as a way to save money for medical expenses while enjoying tax benefits. However, many are still unsure about how HSAs are treated when it comes to taxes like Social Security tax.

So, the burning question is: Is an HSA subject to Social Security tax? The simple answer is no, contributions to an HSA are exempt from Social Security tax. This means that the money you put into your HSA is not subject to Social Security tax deductions.

Here are some key points to keep in mind when it comes to HSAs and Social Security tax:

  • Contributions to an HSA are not subject to Social Security tax deductions.
  • Employers' contributions to employees' HSAs are also exempt from Social Security tax.
  • Withdrawals used for qualified medical expenses are tax-free, including from Social Security tax.
  • If you withdraw money for non-medical expenses before retirement age, you may be subject to income tax and an additional 20% penalty, but not Social Security tax.

HSAs offer a valuable way to save for healthcare costs and reduce your taxable income. Knowing how they are treated in terms of taxes, including Social Security tax, can help you make the most of this financial tool.


Health Savings Accounts (HSAs) are an excellent tool for planning your healthcare finances, providing not just excellent tax benefits but also freedom from Social Security tax.
