What an HSA Is and Why It Matters

This lesson introduces the Health Savings Account as more than a place to park medical cash. Students learn what an HSA is, who it is designed for, how it connects to a high-deductible health plan, and why its tax treatment makes it unusually powerful.

The lesson focuses on the basic structure and purpose of HSAs, not yet on investment selection, contribution strategy, reimbursement tactics, or retirement planning. By the end, students should understand why an HSA can function as both a healthcare reserve and a long-term wealth planning account when used carefully.
