Can You Overdraft an HSA Card? What to Know
Clarify how HSA cards work with your healthcare savings. Understand if overdrafts are possible and how to manage your account funds.
Health Savings Accounts (HSAs) offer a tax-advantaged way for individuals to save and pay for qualified medical expenses. These accounts are typically paired with a high-deductible health plan, allowing contributions to grow tax-free and withdrawals for eligible healthcare costs to be tax-exempt. To facilitate convenient access to these funds, most HSAs come with a dedicated debit card, which serves as a direct payment method for various healthcare-related services and products.
Understanding HSA Card Mechanics
An HSA debit card operates much like a standard debit card, drawing funds directly from the available balance within the linked Health Savings Account. When using the card, the payment is instantly deducted from the account. Unlike credit cards, an HSA card does not extend a line of credit, relying solely on existing funds. Most HSA custodians do not offer built-in overdraft protection features. Transactions are approved only if the account holds sufficient funds.
Consequences of Insufficient Funds
HSA cards typically cannot be overdrawn like a checking account that allows transactions to go through and charges an overdraft fee. Instead, if a transaction is attempted with insufficient funds, it will usually be declined at the point of sale.
An instance where an HSA balance goes negative, even due to a fee or an oversight, can be considered a “prohibited transaction” by the Internal Revenue Service (IRS). Under IRS rules, such as IRC Section 4975, if an account holder engages in a prohibited transaction, the HSA may cease to be recognized as an HSA retroactively to the first day of that year. This can lead to the entire account balance at the start of that year being treated as a taxable distribution, and it may also be subject to an additional 20% penalty tax if the account holder is under age 65. While the HSA custodian generally avoids charging an overdraft fee due to these IRS implications, a merchant or healthcare provider might impose their own fees for returned payments or declined transactions.
Managing Your HSA Balance
Effective management of your HSA balance is important to ensure funds are available when needed and to avoid declined transactions. Regularly checking the account balance before making purchases is a practical step. Most HSA custodians provide convenient ways to monitor funds, such as through online portals or mobile applications, with real-time balances and transaction history.
It is also advisable to consider pending transactions that may not yet be fully reflected in the available balance. Estimating anticipated healthcare expenses and contributing adequately to the HSA can help maintain a healthy balance for expected costs. If an eligible medical expense is incurred when the HSA does not have sufficient funds, individuals can pay for the expense out-of-pocket and then reimburse themselves from the HSA once funds become available.
