Are Pretax HSA Contributions Subject to FICA and Medicare Taxes?

When it comes to Health Savings Accounts (HSAs), one common question that arises is whether pretax contributions to an HSA are subject to FICA and Medicare taxes. The short answer is no, pretax HSA contributions are not subject to FICA or Medicare taxes. This is one of the key advantages of using an HSA to save for medical expenses.

Here's a breakdown of why pretax HSA contributions are not subject to FICA and Medicare taxes:

  • HSAs are funded with pretax dollars, which means that the money you contribute to your HSA is deducted from your gross income before taxes are calculated.
  • Since the contributions are made before taxes, they are not considered part of your taxable income. As a result, they are not subject to FICA (Federal Insurance Contributions Act) taxes or Medicare taxes.
  • By contributing to an HSA with pretax dollars, you can lower your taxable income, reduce the amount of taxes you owe, and ultimately save more money for healthcare expenses.
  • It's important to note that while pretax HSA contributions are not subject to federal taxes, they may still be subject to state income taxes in some states. Be sure to check with your tax professional or advisor to understand the tax implications in your specific situation.

In conclusion, pretax HSA contributions offer a valuable tax advantage by allowing you to save for medical expenses with money that is not subject to FICA and Medicare taxes. This can result in significant cost savings over time and make an HSA a powerful tool for managing healthcare costs.


Understanding Health Savings Accounts (HSAs) can feel overwhelming, but one crucial aspect is whether pretax contributions are subject to FICA and Medicare taxes. The good news is that these contributions are not subject to such taxes, allowing you to maximize your savings for future health-related expenses.
