If you’ve ever heard someone say,

👉 “You should be using an HSA…”

…but had no idea what that actually means — you’re not alone.

Let’s break it down simply.


What Is an HSA?

An HSA (Health Savings Account) is a special type of savings account that allows you to:

  • Set aside money for medical expenses
  • Potentially reduce your taxable income
  • Grow funds over time

👉 Think of it as a healthcare account with built-in tax advantages


Who Can Open an HSA?

Not everyone is eligible.

To open and contribute to an HSA, you must:

  • Be enrolled in a qualified High Deductible Health Plan (HDHP)
  • Not be enrolled in Medicare
  • Not be claimed as a dependent on someone else’s taxes 


What Can You Use an HSA For?

HSA funds can be used for a wide range of qualified medical expenses, including:

  • Doctor visits
  • Prescriptions
  • Dental and vision care
  • Certain over-the-counter items

Why People Are Using HSAs Differently Today

Traditionally, people used HSAs like a checking account:

Put money in → Spend it → Repeat

But more people are starting to treat HSAs as a long-term financial tool instead.

Why?

Because of something called the triple tax advantage.

Important: HSAs and Medicare

One of the biggest mistakes we see is people continuing to contribute to an HSA once they become Medicare-eligible.

👉 That can create tax issues if not handled correctly.
