Contributions to your Health Savings Account (HSA) is a great way to set funds aside for current medical expenses while also saving for expenses in the future. An HSA allows you to make contributions to help grow your savings, and if used for eligible health care expenses, do so tax-free.
If your employer sponsors your HSA plan, you may be able to set up payroll deferrals to contribute to your HSA plan automatically. If not, or you want to submit additional contributions outside of payroll.
Make contributions in just a few easy steps through your online account.
1. Log into your online account and go the Home page.
2. Select Contribute to HSA from the I Want To menu.
