Can You Apply HSA Spent in 2018 for 2017? - Understanding HSA Rules and Contributions

When it comes to Health Savings Accounts (HSAs), understanding the rules and contributions is essential for maximizing the benefits. One common question that arises is, can you apply HSA spent in 2018 for 2017?

The straightforward answer is no, you cannot apply HSA funds spent in 2018 for expenses incurred in 2017. HSA contributions and withdrawals must align with the same calendar year to avoid any tax implications. However, there are some important details to keep in mind when managing your HSA:

  • HSAs offer a triple tax advantage - contributions are tax-deductible, earnings grow tax-free, and withdrawals for qualified medical expenses are tax-free.
  • Contributions to an HSA can be made until the tax filing deadline for that year, usually April 15 of the following year.
  • Unused HSA funds rollover from year to year, allowing you to build a substantial account for future medical expenses.
  • Qualified medical expenses can be incurred in the current year or in the future, as long as they were not reimbursed from another source.

In summary, while you cannot retroactively apply HSA funds spent in a subsequent year for expenses from a previous year, proper planning and understanding of HSA rules can help you make the most of your account.


When considering Health Savings Accounts (HSAs), it's vital to grasp the rules governing contributions and expenditures. A frequent query is, can HSA funds spent in 2018 be applied to expenses from 2017? The answer is a definitive no.
