Is HSA Deferral from Pay Exempt from Social Security Taxes Too?

Health Savings Accounts (HSAs) are a great way to save for medical expenses while enjoying tax benefits. One common question that arises is whether HSA deferrals from pay are exempt from Social Security taxes as well.

When it comes to HSA contributions, the good news is that they are indeed exempt from Social Security (6.2%) and Medicare (1.45%) taxes. This means that the money you contribute to your HSA account is deducted from your gross income before these taxes are calculated.

Here are some key points to remember about HSA contributions and their tax implications:

  • Contributions to your HSA are tax-deductible, reducing your taxable income.
  • HSA funds can be invested and grow tax-free, as long as they are used for qualified medical expenses.
  • Withdrawals for non-medical expenses are subject to income tax and a 20% penalty if taken before age 65.
  • HSA contributions made through payroll deductions are not subject to Social Security or Medicare taxes.

Ultimately, HSAs offer a triple tax advantage: tax-deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses. By taking advantage of these benefits, you can save money on taxes and prepare for future healthcare costs.


If you're considering using a Health Savings Account (HSA) to manage your healthcare costs, it's essential to know about the tax benefits that accompany it. One of the most frequently asked questions is whether HSA deferrals from your paycheck are exempt from Social Security taxes, and the answer is a resounding yes. In fact, contributions made to your HSA are not only exempt from Social Security taxes (6.2%) but also from Medicare taxes (1.45%). This essentially means you get to set aside more money for your healthcare needs without paying these additional taxes.
