Short answer: There is no official guideline for how much HSA money must remain in cash, but keeping a cash reserve helps cover unexpected medical expenses without liquidating investments at the wrong time.

Cash in an HSA: no set percentage

When it comes to your Health Savings Account (HSA), there is no specific requirement on how much of it has to be kept as cash and not invested. However, it's essential to have a portion of your HSA balance in cash to cover any immediate medical expenses that may arise. While there is no set percentage that needs to be kept as cash, it's good practice to have a buffer of readily available funds in your HSA.

In managing your Health Savings Account (HSA), it's important to know that while there's no official guideline on how much money should remain in cash, maintaining a cash reserve is crucial for handling any unexpected medical expenses. It’s wise to keep enough of your HSA funds in cash to ensure you can quickly cover these costs without needing to liquidate investments at the wrong time.

Investing HSA funds for tax-free growth

Investing a portion of your HSA balance can help you grow your savings over time, as any earnings on investments within the HSA are tax-free. By keeping some money invested, you can benefit from the potential for higher returns compared to leaving it all in cash.

How to decide your HSA cash buffer

Here are a few key points to consider when deciding how much of your HSA to keep as cash:

  • Having a cash buffer in your HSA allows you to pay for medical expenses without having to sell investments at potentially unfavorable times.
  • Consider your typical medical expenses and adjust the cash balance accordingly. If you have ongoing medical needs, keeping more cash may be beneficial.
  • Review your investment options within the HSA and choose a mix that aligns with your risk tolerance and financial goals.
